PART I

Item 1. Business

For information regarding the organization of our business segments and our significant customers, see Note 4 of Notes to Consolidated Financial Statements.

Information set forth in Items 1A and 2 below are incorporated by reference into this Item 1.

Introduction

Hecla Mining Company and its subsidiaries have provided precious and base metals to the U.S. and the world since 1891 (in this report, “we” or “our” or “us” refers to Hecla Mining Company and our affiliates and subsidiaries, unless the context requires otherwise). We discover, acquire and develop mines and other mineral interests and produce and market (i) concentrates containing silver, gold, lead, zinc and copper, (ii) carbon material containing silver and gold, and (iii) unrefined doré containing silver and gold. In doing so, we intend to manage our business activities in a safe, environmentally responsible and cost-effective manner.

The silver, zinc and precious metals concentrates and carbon material we produce are sold to custom smelters, metal traders and third-party processors, and the unrefined doré we produce is sold to refiners or further refined before sale of the metals to traders. We are organized and managed in four segments that encompass our operating mines and significant assets being Greens Creek, Lucky Friday, Keno Hill and Casa Berardi.

Our current business strategy is to focus our financial and human resources in the following areas:

---

Metals Prices

Our operating results are substantially dependent upon the prices of silver, gold, lead and zinc, which can fluctuate widely. The volatility of such prices is illustrated in the following table, which sets forth our average realized prices and the high, low and average daily closing market prices for silver, gold, lead, zinc and copper over the last three years. The sources for the market prices are the London Market Fixing prices from the London Bullion Market Association for silver and gold and the Cash Official prices from the London Metals Exchange for lead, zinc and copper.

		2024				2023				2022
Silver (per oz.):
Realized average		$	28.58			$	23.33			$	21.53

The prices of the metals we produce are affected by numerous factors beyond our control. See Item 1A. Risk Factors – A substantial or extended decline in metals prices would have a material adverse effect on us for information on a number of the factors that can impact prices of the metals we produce. Our 2024 realized average prices for all metals we sold, except lead, were higher compared to 2023. In 2023, realized average prices for all metals we sold, except zinc, were higher compared to 2022. We are unable to predict fluctuations in prices for metals and have limited control over the timing of our concentrate shipments which also impacts our realized prices. However, we utilize financially-settled forward contracts for the metals we produce with the objective of managing the exposure to changes in prices of those metals contained in our concentrate shipments between the time of sale and final settlement. In addition, at times we utilize a similar program to manage the exposure to changes in prices of zinc and lead contained in our forecasted future concentrate shipments. See Note 10 of Notes to Consolidated Financial Statements for more information on our base and precious metal forward contract programs.

A comprehensive discussion of our financial results for the years ended December 31, 2024, 2023 and 2022, individual operation performance and other significant items can be found in Item 7. Management’s Discussion and Analysis of Consolidated Financial Condition and Results of Operations , as well as the Consolidated Financial Statements and Notes thereto.

Products and Segments

Our segments are differentiated by geographic region located in North America. We produce silver, zinc, and precious metals flotation concentrates at Greens Creek and silver and zinc flotation concentrates at Lucky Friday, each of which we sell to custom smelters and metal traders. The flotation concentrates produced at Greens Creek and Lucky Friday contain payable silver, zinc and lead, and at Greens Creek they also contain payable gold and at times copper. At Greens Creek, we also produce gravity concentrate containing payable silver, gold and lead. Unrefined bullion (doré) is produced from the gravity concentrate by a third-party processor, and shipped to a refiner before sale of the metals to precious metal traders. Keno Hill is currently in ramp-up and producing silver and precious metal flotation concentrates, but at less than what we consider to be commercial production levels. We also produce unrefined gold and silver bullion bars (doré) and loaded carbon and precipitates at Casa Berardi, which are shipped to refiners before sale of the metals to precious metal traders. At times, we sell loaded carbon and precipitates directly to refiners. Payable metals are those included in our products which we are paid for by smelters, metal traders and refiners. Our segments as of December 31, 2024 included:

Effective January 2024, we revised our internal reporting provided to our Chief Operating Decision Maker, who is our President and Chief Executive Officer to no longer include any financial performance information for our Nevada assets ("Nevada"), reflecting the current status of Nevada being on care and maintenance. General corporate activities not associated with operating mines and their various exploration activities, idle properties and environmental remediation services in the Yukon, Canada, and the previously separately reported Nevada assets are presented as “Other". The presentation of the prior period information discussed in Item 7. Management’s Discussion and Analysis of Consolidated Financial Condition and Results of Operations, and Consolidated Financial Statements and Notes has been revised to reflect this change.

The contributions to our total metals sales by our significant operations in 2024 were 46.4% from Greens Creek, 23.1% from Casa Berardi, 22.3% from Lucky Friday and 8.2% from Keno Hill.

Governmental Regulation

The following is a summary of governmental regulation compliance areas which we believe are significant to our business and may have a material effect on our consolidated financial statements, earnings and/or competitive position.

Health and Safety

We are subject to the regulations of the Mine Safety and Health Administration (“MSHA”) in the United States, the Commission of Labor Standards, Pay Equity and Occupational Health and Safety in Quebec, Workers' Safety and Compensation Board in the Yukon and the Mexico Ministry of Economy and Mining, and work with these agencies to address issues outlined in any investigations and inspections and continue to evaluate our safety practices. We strive to achieve excellent mine safety and health performance, and attempt to implement reasonable best practices with respect to mine safety and emergency preparedness. Achieving and maintaining compliance with regulations is challenging and may increase our operating costs. See Human Capital - Health and Safety below and Item 1A. Risk Factors – We face substantial governmental regulation, including the Mine Safety and Health Act, various environmental laws and regulations and the 1872 Mining Law .

---

Environmental

Our operations are subject to various environmental laws and regulations at the federal and state/provincial/territorial level. Compliance with environmental regulations, and litigation based on environmental laws and regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities. For example, since acquiring the Keno Hill mine in September 2022, the site has experienced permit exceedances involving the quality of water discharged into the environment. We are working to assess and improve the existing infrastructure and the environmental management system that was put in place by the previous owners. As part of this process, we have submitted plans to the Yukon Department of Energy, Mines and Resources to upgrade the water treatment plant at the Bermingham mine within our Keno Hill operations and in the interim have made other upgrades to water treatment at the site. See Note 16 of Notes to Consolidated Financial Statements .

Keno Hill is located at a site in the Yukon Territory where extensive historical mining activity occurred. The mining claims and rights that comprise our Keno Hill mine are owned by two of our indirect, wholly-owned subsidiaries, Alexco Keno Hill Mining Company and Elsa Reclamation & Development Company Ltd. (“ERDC”). ERDC and Alexco are parties to the Amended and Restated Subsidiary Agreement (“ARSA”) dated July 18, 2013, among them and Her Majesty the Queen in right of Canada (“Canada”) which addresses the pre-existing environmental condition and the environmental care and maintenance and reclamation of the historical Keno Hill site. Under the ARSA and related documents, ERDC, as a paid contractor for the Yukon Government, is responsible for the development and eventual implementation of the district wide reclamation and closure plan (“Reclamation Plan”) which addresses the historic environmental liabilities of the district from past mining activities pre-dating Hecla’s (and Alexco's) acquisition of the Keno Hill project, as well as for carrying out care and maintenance at various locations within the historical Keno Hill site until the Reclamation Plan is implemented. Hecla’s predecessor, Alexco, previously deposited CDN$10 million in a trust which funds ERDC’s maximum contribution toward implementing the Reclamation Plan, and agreed to a 1.5% net smelter royalty capped at CAD$4 million, of which approximately CAD$2.8 million has been paid or accrued for as of December 31, 2024. ERDC receives agreed-to commercial contractor rates when retained by Canada to provide environmental services in the historical Keno Hill site outside the scope of care and maintenance and closure and reclamation planning under the ARSA (in the latter case, for which ERDC receives an annual fee of CAD$900,000 from Canada, adjustable for material changes in scope). The potential liabilities associated with the pre-existing environmental conditions at Keno Hill are indemnified by Canada under the terms and conditions of the ARSA, subject to the requirement for ERDC to develop, permit, and implement the Reclamation Plan, or if Hecla and Canada agree to transfer portions of the historic area to active mining operations within the Keno Hill unit, then such indemnification ceases to the extent of such transferred area. Completing the Reclamation Plan is expected to take approximately 5 more years and is currently estimated to cost approximately CAD$348 million over that time, for which we expect ERDC to be reimbursed for all material costs incurred. However, we are at risk for any variance in timing between expending funds by ERDC and reimbursement by Canada, as well as for any disputed or otherwise non-reimbursed costs (for example if ERDC were to act outside of the scope of the ARSA). In addition, ERDC is responsible for sharing with Canada (i) under certain circumstances, care and maintenance costs pending implementation of the Reclamation Plan, (ii) detailed design and engineering costs to support the Reclamation Plan and (iii) under certain circumstances, post active reclamation costs (i.e. in the event Hecla has brought a historical area with pre-existing environmental conditions into active operations at the Keno Hill unit), which, in each case and in the aggregate, we do not anticipate will have a material impact on our financial results as a whole.

Mine closure and reclamation regulations impose substantial costs on our operations and include requirements that we provide financial assurance supporting those obligations. We currently have $213.6 million of financial assurances, primarily in the form of surety bonds, for reclamation company-wide. We anticipate approximately $7.3 million in expenditures in 2025 for environmental permit compliance and idle property management. We also plan to invest approximately $3.5 million for on-going reclamation work at the former Troy Mine in Montana. The projected remaining cost for reclamation at the site is included in our accrued reclamation and closure costs liability. See Item 1A. Risk Factors – We face substantial governmental regulation, including the Mine Safety and Health Act, various environmental laws and regulations and the 1872 Mining Law ; Our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations ; Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities; Mine closure and reclamation obligations impose substantial costs on our operations; Our environmental and asset retirement obligations may exceed the provisions we have made ; and New federal and state laws, regulations and initiatives could impact our operations .

Licenses, Permits and Claims/Concessions

We are required to obtain various licenses and permits to operate our mines and conduct exploration and reclamation activities. See Item 1A. Risk Factors – We are required to obtain governmental permits and other approvals in order to conduct mining operations . We can only engage in exploration at our exploration sites such as the Hollister and Hatter Graben (Nevada) and Libby Exploration (Montana) projects if we are successful in obtaining necessary permits. Similarly, mining at our planned open pits at Casa Berardi requires permits we have not yet received. At the Libby Exploration project (formerly known as Montanore), in February 2022, we submitted a new Plan of Operations to the United States Forest Service limited to underground exploration and evaluation activities that is currently under an Environmental Assessment review (“EA”) under the National Environmental Policy Act (“NEPA”). Upon

---

successful completion of the EA process, and if subsequent data collection and analysis activities suggest development of a mine is feasible, then it is anticipated that a new Plan of Operations for the construction and development of a mine at the Libby Exploration site would be submitted for approval. See Item 1A. Risk Factors – We are required to obtain governmental permits and other approvals in order to conduct mining operations and Legal challenges could prevent our projects in Montana from ever being developed .

In addition, our operations and exploration activities in Canada are conducted pursuant to claims granted by the host government, and are subject to claims renewal and minimum work commitment requirements, which are subject to certain political risks associated with foreign operations. See Item 1A. Risk Factors – Our foreign activities are subject to additional inherent risks , Our operations and properties in Canada expose us to additional political risks and Certain of our mines and exploration properties are located on land that is or may become subject to traditional territory, title claims and/or claims of cultural significance, and such claims and the attendant obligations of the federal government to those tribal communities and stakeholders may affect our current and future operations.

Taxes and Royalties

We are subject to various taxes and government royalties in the jurisdictions where we operate, including those specific to mining activities. These include: federal income taxes; state/provincial income taxes; county/city and bureau property taxes and sales and use tax in the U.S.; goods and services tax in Canada; value added tax in Mexico; mining-specific taxes in Alaska, Idaho, Nevada, Quebec and the Yukon; and mining royalties in Alaska, Nevada and Canada. Accrual and payment of taxes and accounting for deferred taxes can involve significant estimates and assumptions and can have a material impact on our consolidated financial statements. Tax rates and the calculations of taxes can change significantly and are influenced by changes in political administrations and other factors. See Item 1A. Risk Factors – Our accounting and other estimates may be imprecise ; Our ability to recognize the benefits of deferred tax assets related to net operating loss carryforwards and other items is dependent on future cash flows generating taxable income ; Our foreign activities are subject to additional inherent risks ; and We face substantial governmental regulation, including the Mine Safety and Health Act, various environmental laws and regulations and the 1872 Mining Law . Also, s ee Note 7 of Notes to Consolidated Financial Statements for more information on income and mining taxes.

Physical Assets

Our business is capital intensive and requires ongoing capital investment for the replacement, modernization and expansion of equipment and facilities and to develop new mineral reserves. At December 31, 2024, the book value of our properties, plants, equipment and mine development, net of accumulated depreciation, was approximately $2.7 billion. For more information see Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. We maintain insurance policies against property loss and business interruption. However, such insurance contains exclusions and limitations on coverage, and there can be no assurance that claims would be paid under such insurance policies in connection with a particular event. When we do experience insurable losses – such as with the fire at the Lucky Friday in August and September of 2023 – it can take a long period of time before we receive any or all insurance proceeds. See Item 1A. Risk Factors – Our operations may be adversely affected by risks and hazards associated with the mining industry that may not be fully covered by insurance .

Human Capital

As of December 31, 2024, we had approximately 1,830 employees, of which approximately 1,070 were employed in the United States, 750 in Canada, and 10 in Mexico. The vast majority of our employees are full-time. Approximately 260 of our employees at the Lucky Friday were covered by a collective bargaining agreement.

The attraction, development and retention of people is critical to delivering our business strategy. Key areas of focus for us include:

Health and Safety

The safety and health of our employees is of paramount importance. Our goal is to achieve world-class safety and health performance by promoting a deeply rooted value-based culture of safety and utilizing technology and innovation to continually improve the safety at our operations. We know that employees' and contractors' safety awareness is fundamental to making our workplace as safe as possible. Therefore, we invest in training and workforce development programs that focus on safety first. All employees and contractors receive training that complies with or exceeds the applicable safety and health regulations as set by the governing body in the jurisdiction in which each operation is located. As part of our commitment to safety, we track a variety of safety performance indicators, including injuries, near misses, observations, and equipment damages. Our goal is to reduce safety incidents. Our All Injury Frequency Rate (“AIFR”) is calculated as the number of incidents in the period multiplied by 200,000 hours and divided by the number of hours worked in the period. Company-wide, our AIFR was 1.86 for 2024.

---

Compensation and Benefits

We are among the largest private-sector employers in the communities in which we operate providing a compensation and benefits package that attracts, motivates, and retains employees. In addition to competitive base wages, and incentive compensation, we offer retirement benefits, health insurance plans and paid time off.

Retention and Employee Development

We are committed to hiring talented people, developing effective leaders, providing an inclusive workplace and retaining a large portion of the workforce for long periods of time. The mining workforce of the future, like most industries, will see a continual change in the jobs and skill sets required as we adopt new technologies and make our workplace safer and more efficient. We are also committed to helping employees update their skills. For example, in conjunction with a trade school in Val-d’Or, Quebec, the leadership at our Casa Berardi mine has developed a customized training program for new and existing supervisors to develop their skills in the areas of leadership, communications, roles and responsibilities, and health and safety. In addition, we have long supported the Pathways to Mining Careers program, a career training partnership with the University of Alaska Southeast in Juneau. We also offer a reimbursement program to assist with educational expenses for employees who are interested in furthering their education. Advanced education can improve job performance and increase advancement opportunities for the employee, while providing flexibility to our company by increasing the employee’s knowledge base and skill set.

Annual employee surveys are conducted to gauge employee concerns and morale. The results of the surveys, and any responsive measures, are shared with our Board of Directors. Strategic talent reviews and succession planning reviews are conducted periodically across all business areas, and our training programs are adapted accordingly. The Chief Executive Officer (“CEO”), senior level company leadership and the Board of Directors periodically review our top talent. Creating more opportunities for women and indigenous people are among our priorities for employee development. We also strive to maintain an inclusive workplace and provide periodic training to employees to help meet that goal. Our employees are required to abide by our Code of Conduct, which is provided to employees upon being hired and thereafter annually, and is available on our website, to promote the conduct of our business in a consistently legal and ethical manner. Among other provisions, the Code of Conduct reflects our policy and practice not to discriminate against any employee because of race, color, religion, national origin, sex, sexual orientation, gender identity or expression, age, or physical or other disability. We expect our leaders to set the example by being positive role models and good mentors for our employees.

Our Senior Vice President - Chief Administrative Officer is responsible for developing and executing our human capital strategy. The position is an executive-level position to reflect the priority we place on utilizing our human capital resources to meet our business strategy.

Item 1A. Risk Factors

The following risks and uncertainties, together with the other information set forth in this report, should be carefully considered by those who invest in our securities. Any of the following material risk factors could adversely affect our business, financial condition or operating results and could decrease the value of our common or preferred stock or other outstanding securities. These are not all of the risks we face, and other factors not presently known to us or that we currently believe are immaterial may also affect our business if they occur.

Financial Risks

A substantial or extended decline in metals prices would have a material adverse effect on us.

Our revenue is derived primarily from the sale of concentrates and doré containing silver, gold, lead, zinc and copper and, as a result, our earnings are directly related to the prices of these metals. Silver, gold, lead, zinc and copper prices fluctuate widely and are affected by numerous factors, including:

These factors are largely beyond our control and are difficult to predict. If the market prices for these metals fall below our production or development costs for a sustained period of time, we will experience losses and may have to discontinue exploration, development or operations, and we may also incur asset write-downs at one or more of our properties. See Item 1. Business - Introduction for information on the average, high, and low daily closing prices for silver, gold, lead, zinc and copper for the last three years. On February 7, 2025, the closing prices for silver, gold, lead, zinc and copper were $31.78 per ounce, $2,860.10 per ounce, $0.90 per pound, $1.28 per pound, and$ 4.16 per pound, respectively.

An extended decline in metals prices, an increase in operating or capital costs or treatment charges, mine accidents or closures, increasing regulatory obligations, or our inability to convert resources or exploration targets to reserves may cause us to record write-downs, which could negatively impact our results of operations.

When events or changes in circumstances indicate the carrying value of our long-lived assets may not be recoverable, (a "triggering event") we review the recoverability of the carrying value by estimating the future undiscounted cash flows expected to result from the use and eventual disposition of the asset. Impairment must be recognized when the carrying value of the asset exceeds these cash flows. Recognizing impairment write-downs could negatively impact our results of operations. Metals price estimates are a key component used in the evaluation of the carrying values of our assets, as the evaluation involves comparing carrying values to the probability weighted estimated undiscounted cash flows resulting from operating plans using various metals price scenarios. Our estimates of undiscounted cash flows for our long-lived assets also include an estimate of the market value of the resources and exploration targets beyond the current operating plans.

We determined no impairments was required for a triggering event identified during 2024. For more discussion, see the below risk factors, “ We may not realize all of the anticipated benefits from our acquisitions, including our 2022 acquisition of Alexco" and “ Issues we have faced at certain segments could require us to write-down the carrying value of associated long-lived assets. We could face similar issues at our other operations. Such write-downs may adversely affect our results of operations and financial condition. ” If the prices of the metals we produce decline for an extended period of time, if we fail to control production or capital costs, if regulatory issues increase costs or decrease production, or if we do not realize the mineable mineral reserves, resources or exploration targets at our mining properties, we may be required to recognize asset write-downs in the future. In addition, the perceived market value of the resources and exploration targets of our properties is dependent upon prevailing metals prices as well as our ability to discover economic ore. A decline in metals prices for an extended period of time or our inability to convert resources or exploration targets to reserves could significantly reduce our estimates of the value of the resources or exploration targets at our properties and result in asset write-downs.

---

We have a substantial amount of debt that could impair our financial health and prevent us from fulfilling our obligations under our existing and future indebtedness.

As of December 31, 2024, we had total indebtedness of approximately $558.7 million, primarily in the form of our Senior Notes and borrowings under our amended revolving credit agreement. Our level of debt, debt service obligations and covenant requirements may have adverse effects on our business, financial condition, cash flows or results of operations, including:

We and our subsidiaries may incur substantial additional indebtedness in the future. Although the indenture governing our Senior Notes contains restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of significant qualifications and exceptions and, under certain circumstances, the amount of additional indebtedness that could be incurred in compliance with these restrictions could be substantial. In May 2024, we entered into an amended revolving credit agreement (the "Credit Agreement") which increased borrowing capacity to $225 million. Like the indenture, the credit agreement governing the revolving credit facility also has restrictions on the incurrence of additional indebtedness but with a number of significant qualifications and exceptions. If new debt is added to our and our subsidiaries’ existing debt levels, the risks associated with such debt that we currently face would increase. In addition, the indenture governing the Senior Notes does not prevent us from incurring additional indebtedness under the indenture.

We have had losses that could reoccur in the future.

We have experienced volatility in our net income (loss) reported in the last three years, as shown in our Consolidated Statement of Operations and Comprehensive Income (Loss) , including net income of $35.8 million in 2024, net losses of $84.2 million and $37.3 million in 2023 and 2022, respectively. A comparison of operating results over the past three years can be found in Results of Operations in Item 7. Management ’ s Discussion and Analysis of Financial Condition and Results of Operations.

Many of the factors affecting our operating results are beyond our control, including, but not limited to, the volatility of metals prices; smelter terms; rock and soil conditions; seismic events; cybersecurity attacks; availability of hydroelectric power; diesel fuel prices; interest rates; foreign exchange rates; global or regional political or economic policies; inflation; availability and cost of labor; economic developments and crises; governmental regulations; continuity of orebodies; ore grades; recoveries; performance of equipment; uninsured losses; price speculation by certain investors; and purchases and sales by central banks and other holders and producers of gold and silver in response to these factors. We cannot assure you that we will not experience net losses in the future.

Our accounting and other estimates may be imprecise.

Preparing consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts and related disclosure of assets, liabilities, revenue and expenses at the date of the consolidated financial statements and reporting periods. The more significant areas requiring the use of management assumptions and estimates relate to:

---

Future estimates and actual results may differ materially from these estimates as a result of using different assumptions or conditions. For additional information, see Critical Accounting Estimates in Item 7. Management ’ s Discussion and Analysis of Financial Condition and Results of Operations , Note 2 of Notes to Consolidated Financial Statements, and the risk factors set forth below: “ Our costs of extending existing reserves or development of new orebodies and other capital costs may be higher and provide less return than we estimated, ” “ Our mineral reserve and resource estimates may be imprecise, ” “ We are currently involved in ongoing legal disputes that may materially adversely affect us, ” and “ Our environmental and asset retirement obligations may exceed the provisions we have made. ”

Commodity and currency risk management activities could prevent us from realizing possible revenues or lower costs or expose us to losses.

We periodically engage in risk management activities to manage the exposure to changes in prices of silver, gold, lead and zinc contained in our concentrate shipments between the time of sale and final settlement and manage the exposure to changes in the prices of lead and zinc contained in our forecasted future shipments. Such activities are utilized in an attempt to partially insulate our operating results from changes in prices for those metals. However, such activities may prevent us from realizing revenues in the event that the market price of a metal exceeds the price stated in a forward contract, and may also result in significant mark-to-market fair value adjustments, which may have a material adverse impact on our reported financial results. In addition, we are exposed to credit risk with our counterparties, and we may experience losses if a counterparty fails to purchase under a contract when the contract price exceeds the spot price of a commodity.

We also use financially-settled forward contract programs to manage exposure to fluctuations in the exchange rates between the U.S. dollar (“USD”) and the Canadian dollar (“CAD”) and the impact on our future operating costs denominated in CAD. We use a similar program related to future development costs denominated in CAD. As with our metals derivatives, when utilized, such activities may prevent us from realizing possible lower costs on a USD-basis in the event that the USD strengthens relative to the CAD compared to the exchange rates stated in the forward contracts, and also expose us to counterparty credit risk.

See Note 10 of Notes to Consolidated Financial Statements for more information on these forward contract programs.

Our ability to recognize the benefits of deferred tax assets related to net operating loss carryforwards and other items is dependent on future cash flows generating taxable income.

We recognize the expected future tax benefit from deferred tax assets when the tax benefit is considered to be more likely than not of being realized. Otherwise, a valuation allowance is applied against deferred tax assets, reducing the value of such assets. Assessing the recoverability of deferred tax assets requires management to make significant estimates related to expectations of future taxable income. Estimates of future taxable income are based on forecasted income from operations and the application of existing tax laws in each jurisdiction. Metal prices, reserves, production and cost estimates are key components to determine the expected future benefit of our deferred tax assets. To the extent that future taxable income differs significantly from estimates as a result of a decline in metals prices or other factors, our ability to realize the deferred tax assets could be impacted. Additionally, significant future issuances of common stock or common stock equivalents, or changes in the direct or indirect ownership of our common stock or common stock

---

equivalents, could limit our ability to utilize our net operating loss carryforwards pursuant to Section 382 of the Internal Revenue Code. Future changes in tax law or changes in ownership structure could limit our ability to utilize our recorded tax assets. Our deferred tax assets as of December 31, 2024 were $252.7 million, net of $115.1 million in valuation allowances. See Note 7 of Notes to Consolidated Financial Statements for further discussion of our deferred tax assets.

Returns for investments in pension plans and pension plan funding requirements are uncertain.

We maintain defined benefit pension plans for most U.S. employees, which provide for defined benefit payments after retirement for those employees. Canadian and Mexican employees participate in public retirement systems for those countries and are not eligible to participate in the defined benefit pension plans that we maintain for U.S. employees. The ability of the pension plans maintained for U.S. employees to provide the specified benefits depends on our funding of the plans and returns on investments made by the plans. Returns, if any, on investments are subject to fluctuations based on investment choices and market conditions. In addition, we have a supplemental excess retirement plan which was funded as of December 31, 2024. A sustained period of low returns or losses on investments, or future benefit obligations that exceed our estimates, could require us to fund the pension plans to a greater extent than anticipated. See Note 6 of Notes to Consolidated Financial Statements for more information on our pension plans.

Operation, Climate, Development, Exploration and Acquisition Risks

Natural disasters, public health crises, political crises, and other catastrophic events or other events outside of our control may materially and adversely affect our business or financial results.

If any of our facilities or the facilities of our suppliers, third-party service providers, or customers is affected by natural disasters, such as earthquakes, floods, fires, power shortages or outages, public health crises (such as pandemics and epidemics), political crises (such as terrorism, war, political instability or other conflict), or other events outside of our control, our operations or financial results could suffer. Any of these events could materially and adversely impact us in a number of ways, including through decreased production, increased costs, decreased demand for our products due to reduced economic activity or other factors, or the failure by counterparties to perform under contracts or similar arrangements. For example, the COVID-19 pandemic impacted our operations and financial results between 2020 and 2022.

Our operations are subject to a range of risks related to climate change and transitioning the business to meet regulatory, societal and investor expectations for operating in a low-carbon economy.

Climate change is expected to create more extreme weather patterns that can increase frequency or severity of forest fires (such as our Casa Berardi unit experienced in summer 2023) and droughts and sudden heavy rainfall (such as our Greens Creek unit has periodically experienced). These latter two events require careful water management. Potential key material physical risks to Hecla from climate change include, but are not limited to:

Such events can temporarily slow or halt operations due to physical damage to assets, unavailability of power, reduced worker productivity for safety protocols on site related to extreme weather events, and difficulties transporting workers, materials or supplies to or from sites. Additional financial impacts could include increased capital or operating costs to (i) increase water storage and treatment capacity, (ii) obtain or develop maintenance and monitoring technologies, (iii) increase resiliency of facilities and (iv) establish supplier climate resiliency and contingency plans. The occurrence of weather and climate events have in the past and could in the future cause us to incur unplanned costs, which may be material, to address or prevent resulting damage. See the below Risk Factors “We may be subject to a number of unanticipated risks related to inadequate infrastructure” and “Our operations may be adversely affected by risks and hazards associated with the mining industry that may not be fully covered by insurance."

---

In addition, we have identified opportunities and potential risks for Hecla as we shift toward a low-carbon economy. Technologies that support decarbonization include renewable energy sources, electric vehicles, and energy storage, all of which require the metals we produce. However, renewable energies currently may not have the same reliability as conventional energy sources. Thus, as we transition toward renewable energy sources, we could experience a possible curtailment of our energy supply, and these new energy sources may cost more in the future than our current supplies, which could negatively impact our financial performance. Further, transitioning to a lower-carbon economy will require significant investment and may entail extensive policy, legal, technology, and market changes to address mitigation and adaptation requirements related to climate change. Depending on the nature, speed, focus and jurisdiction of these changes, transition risks may pose varying levels of financial and reputational risk to our business.

Policy and regulatory risk related to actual and proposed changes in climate and water-related laws, regulations and taxes developed to regulate the transition to a low-carbon economy may result in increased costs for our operations, third-party smelters and refiners and our suppliers, including increased energy, capital equipment, environmental monitoring and reporting and other costs to comply with such regulations. Regulatory uncertainty may cause higher costs and lower economic returns than originally estimated for new development projects and operations, including closure reclamation and remediation obligations.

The development and deployment of technological improvements or innovations will be required to support the transition to a low-carbon economy, which could result in write-offs and early retirement of existing assets, increased costs to adopt and deploy new practices and processing including planning and design for mines, development of alternative power sources, site level efficiencies and other capital investments.

A failure to meet our climate strategy commitments and/or societal or investor expectations could also result in damage to our reputation, decreased investor confidence and challenges in maintaining positive community relations, which can pose additional obstacles to our ability to conduct our operations and develop our projects, which may result in a material adverse impact on our business, financial position, results of operations and growth prospects.

Mining accidents or other adverse events at an operation could decrease our anticipated production or otherwise adversely affect our operations.

Production may be reduced below our historical or estimated levels for many reasons, including, but not limited to, mining accidents; unfavorable ground or shaft conditions; extreme weather events; fire, influx of water or other insured and uninsured events; work stoppages or slow-downs; lower than expected ore grades; cybersecurity attacks; unexpected regulatory actions; if the metallurgical characteristics of ore are less economic than anticipated; or because our equipment or facilities fail to operate properly or as expected. Our mines are subject to risks relating to ground instability, including, but not limited to, pit wall failure, crown pillar collapse, seismic events, backfill and stope failure or the breach or failure of a tailings or other impoundment. Both the Lucky Friday and Casa Berardi mines have a history of ground instability underground and related incidents which in the past have resulted in loss of production at these facilities and some of the other effects described below. The occurrence of an event such as those described above could result in loss of life or temporary or permanent cessation of operations, any of which could have a material adverse effect on our financial condition and results of operations. Other closures or impacts on operations or production may occur at any of our mines at any time, whether related to accidents, changes in conditions, changes to regulatory policy, or as precautionary measures. See “Our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations. Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities.”

In addition, our operations are typically in remote locations, where conditions can be inhospitable, including with respect to weather, surface conditions, interactions with wildlife or otherwise in or near dangerous conditions. In the past we have had employees, contractors, or employees of contractors get injured, sometimes fatally, while working in such challenging locations. An accident or injury to a person at or near one of our operations could have a material adverse effect on our financial condition and results of operations.

At the Lucky Friday mine we are mining ever deeper deposits and have been utilizing our patented Underhand Closed Bench (“UCB”) mining method. See Item 2. Properties - Lucky Friday for a description of the UCB method. We started testing the UCB method in 2020 and it was used for approximately 86%, 87% and 88% of the tons mined at Lucky Friday in 2024, 2023 and 2022, respectively. The UCB method has not been used at other mines. Although we believe the testing has resulted in better management of the Lucky Friday mine’s seismicity, which increases as we mine deeper, we cannot predict unknown hazards that the UCB method or our deeper mining activities might cause.

Our operations may be adversely affected by risks and hazards associated with the mining industry that may not be fully covered by insurance.

---

Our business is capital intensive, requiring ongoing investment for the replacement, modernization or expansion of equipment and facilities. Our mining and milling operations are subject to risks of process disruptions and equipment malfunctions. Equipment and supplies may from time to time be unavailable on a timely basis. Our business is subject to a number of other risks and hazards including:

Such risks could result in:

---

We maintain insurance to protect against losses that may result from some of these risks, such as property loss and business interruption, in amounts we believe to be reasonably consistent with our historical experience, industry practice and circumstances surrounding each identified risk. Such insurance, however, contains exclusions and limitations on coverage, particularly with respect to environmental liability, political risk and seismic events. We cannot assure you that claims would be paid under such insurance policies in connection with a particular event. Insurance specific to environmental risks is generally either unavailable or, we believe, cost prohibitive, and we therefore we maintain limited environmental insurance. Occurrence of events for which we are not insured may have an adverse effect on our business.

Our costs of extending existing reserves or development of new orebodies and other capital costs may be higher and provide less return than we estimated.

Capitalized development projects may cost more and provide less return than we estimate. If we are unable to realize a return on these investments, we may incur a related asset write-down that could adversely affect our financial results or condition.

Our ability to sustain or increase our current level of metals production partly depends on our ability to develop new orebodies and/or expand existing mining operations. Before we can begin a development project, we must first determine whether it is economically feasible to do so. This determination is based on estimates of several factors, including:

Many of these estimates are based on geological and other interpretive data, which may be imprecise. As a result, actual operating and capital costs and returns from a development project may differ substantially from our estimates, and, as such, it may not be economically feasible to continue with a development project.

---

Our mineral reserve and resource estimates may be imprecise.

Our mineral reserve figures are primarily estimates and are not guarantees that we will recover the indicated quantities of these metals. You are cautioned not to place undue reliance on estimates of reserves (or resource estimates or exploration targets). Reserves are estimates made by our professional technical personnel of the amount of metals that they believe could be economically and legally extracted or produced at the time of the reserve determination. No assurance can be given that the estimated amount of metal or the indicated level of recovery of these metals will be realized. Reserve and resource estimation is an interpretive process based upon available data and various assumptions. Our reserve and resource estimates may change. Reserves are valued based on estimates of costs and metals prices, which may not be consistent among our properties or across the industry. The estimated quantities and economic value of mineral reserves may be adversely affected by:

Furthermore, short-term operating factors relating to our mineral reserves, such as the need to sequentially develop orebodies and the processing of new or different ore grades, may adversely affect our cash flow.

If the prices of metals that we produce decline substantially below the levels used to calculate reserves for an extended period, we could experience:

Additionally, reserve estimates are subject to further development and preproduction drilling, resource estimates and exploration targets are subject to further exploration and development, and are, therefore, subject to considerable uncertainty. Despite our history of converting resources and exploration targets to reserves through additional drilling and study work, we cannot be certain that any part or parts of resources or exploration targets will ever be confirmed or converted into reserves as defined by the SEC.

Efforts to expand the finite lives of our mines may not be successful or could result in significant demands on our liquidity, which could hinder our growth.

---

One of the risks we face is that mines are depleting assets. Thus, in order to maintain or increase production we must continually replace depleted mineral reserves by locating and developing additional ore. Our ability to expand or replace mineral reserves primarily depends on the success of our exploration programs. Mineral exploration, particularly for silver and gold, is highly speculative and expensive. It involves many risks and is often non-productive. Even if we believe we have found a valuable mineral deposit, it may be several years before production from that deposit is possible. During that time, it may become no longer feasible to produce those minerals for economic, regulatory, political or other reasons. As a result of high costs and other uncertainties, we may not be able to expand or replace our existing mineral reserves as they are depleted, which would adversely affect our business and financial position in the future.

Our ability to market our metals production depends on the availability of smelters and/or refining facilities and our operations and financial results may be affected by disruptions or closures or the unavailability of smelters and/or refining facilities for other reasons.

We sell our metals products to smelters and metal traders. Our doré bars are sent to refiners for further processing before being sold to metal traders. Access to refiners and smelters on terms which are economic is critical to sell our products to buyers and generate revenues. If smelters or refiners are unavailable or unwilling to accept our products, or we are otherwise unable to sell our products to customers on acceptable commercial and legal terms, our operations and financial results could be adversely affected. See Note 4 of Notes to Consolidated Financial Statements for more information on the distribution of our sales and our significant customers.

We derive a significant amount of revenue from a relatively small number of customers and occasionally enter into concentrate spot market sales with metal traders.

For the fiscal year ended December 31, 2024, our three largest customers accounted for approximately 28%, 19% and 17%, respectively, of our total revenues. Given our operations produce unique qualities of concentrates, which a limited number of smelters can process effectively, we enter into long-term benchmark contracts for a majority of our total concentrates production. We expose lesser portions of our concentrates production to spot market sales to metal traders to benefit from favorable spot market sales terms from time to time. Our results of operations, financial condition and cash flows could be materially adversely affected if one or more of our long-term customers were to decide to interrupt or curtail their activities, terminate their contracts with us or fail to renew existing contracts. Additionally, if spot market conditions deteriorate rapidly, we could have difficulty selling a portion of our concentrates, and metal traders could refuse to perform under existing contracts, which could also result in materially adverse effects on our results of operations, financial conditions and cash flows. See Note 4 of Notes to Consolidated Financial Statements for more information on the distribution of our sales and our significant customers.

Shortages of critical parts and equipment may adversely affect our operations and development projects.

We have been impacted, from time to time, by increased demand for critical resources such as input commodities, drilling equipment, trucks, shovels and tires. These shortages have, at times, impacted the efficiency of our operations, and resulted in cost increases and delays in construction of projects; thereby impacting operating costs, capital expenditures and production and construction schedules.

Our foreign activities are subject to additional inherent risks.

We currently have operations in Canada (and limited activities in Mexico), and we expect to continue to conduct operations there and possibly other international locations in the future. Because we conduct operations internationally, we are subject to political, social, legal and economic risks such as:

---

The occurrence of any one or combination of these events, many of which are beyond our control, could materially adversely affect our financial condition or results of operations.

Our operations and properties in Canada expose us to additional political risks.

Our properties in Canada may be of particular interest or sensitivity to one or more interest groups, including aboriginal groups (which are generally referred to as “First Nations”). We have mineral projects in Quebec, the Yukon and British Columbia that are or may be in areas with a First Nations presence. The nature and extent of First Nation rights and title remains the subject of active debate, claims and litigation in Canada. Intergovernmental relations between First Nation authorities and federal, provincial and territorial authorities are evolving. It is our practice to work closely with and consult with First Nations in areas in which our projects are located or which could be impacted by our activities. However, it is possible that our permitting activities, profitable production, exploration or development activities on our Canadian properties could be delayed, interrupted or otherwise adversely affected in the future by political uncertainty, native land claims entitlements, expropriations of property, financial arrangements, changes in applicable law, governmental policies and policies of relevant interest groups, including those of First Nations. Any changes in law or relations or shifts in political conditions may be beyond our control, or we may enter into agreements with First Nations, all of which may adversely affect our business and operations and if significant, may result in the impairment or loss of mineral concessions or other mineral rights, or may make it impossible to continue our mineral production, exploration or development activities in the applicable area, any of which could have an adverse effect on our financial condition and results of operations.

Certain of our mines and exploration properties are located on land that is or may become subject to traditional territory, title claims and/or claims of cultural significance, and such claims and the attendant obligations of the federal government to those tribal communities and stakeholders may affect our current and future operations.

Indigenous interests and rights as well as related consultation issues may impact our ability to pursue exploration, development and mining at certain of our properties in Nevada, Montana, Alaska, British Columbia, the Yukon and Quebec. There is no assurance that claims or other assertion of rights by tribal communities and stakeholders or consultation issues will not arise on or with respect to our properties or activities. These could result in significant costs and delays or materially restrict our activities. Opposition by tribal communities and stakeholders to our presence, operations or development on land subject to their traditional territory or title claims or in areas of cultural significance could negatively impact us in terms of permitting delay, public perception, costly legal proceedings, potential blockades or other interference by third parties in our operations, or court-ordered relief impacting our operations. In addition, we may be required to, or may voluntarily, enter into certain agreements with such tribal communities in order to facilitate development of our properties, which could reduce the expected earnings or income from any future production. For example, although our Keno Hill

---

subsidiary is a party to a Cooperation and Benefits Agreement with the First Nation of Na-Cho Nyäk Dun (“FNNND”), in whose traditional territory Keno Hill is located, the agreement does not address wealth sharing, and instead the parties have deferred such discussions. We expect in the future the parties will negotiate the wealth sharing requirement of the agreement, and thus Keno Hill will likely make future and ongoing payments to the FNNND.

In June 2024, in the aftermath of the Victoria Gold Eagle Mine heap leach pad failure in the Yukon, Canada, the Yukon Government (“YG”) and the FNNND was focused on response and cleanup activities required as a result of the incident. As a result, we experienced and continue to experience delays on permitting matters at our Keno Hill mine which, although not a heap leach operation, is located not far from the Eagle Mine (the YG is obligated to consult with FNNND on permitting matters). These delays could have an adverse impact on our Keno Hill operations and will delay reaching increased production levels at the mine. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Results of Operations – Keno Hill.

We may be subject to a number of unanticipated risks related to inadequate infrastructure.

Mining, processing, development, exploration and other activities depend on adequate infrastructure. Reliable roads, bridges, ports, power sources, internet access and water supply are important to our operations, and their availability and condition affect capital and operating costs. Unusual, infrequent or extreme weather phenomena, sabotage, amount or complexity of required investment, or other interference in the maintenance or provision of such infrastructure, or government intervention, could adversely affect our mining operations. For example, Yukon Energy, the provider of electricity to Keno Hill, recently experienced a turbine failure at its hydroelectric plant in Whitehorse. That failure, combined with cold temperatures in the Yukon, has caused Yukon Energy to reduce power to Keno Hill, which does not have sufficient backup generation capacity to fully power the mine and the mill. As a result, on several occasions in late 2024 and early 2025, Keno Hill has had insufficient power to run the mine and the mill. Although such power disruptions have not yet had a material impact on Keno Hill’s operations, we expect that power interruptions will continue throughout the cold weather months of 2025 until the turbine is repaired by Yukon Energy (currently expected in summer 2025), and such interruptions could have a material adverse impact on the financial condition of and results of operations at Keno Hill.

We face inherent risks in acquisitions of other mining companies or properties that may adversely impact our growth strategy.

We actively evaluate opportunities to expand our mineral reserves and resources by acquiring other mining companies or properties. Although we are pursuing opportunities that we feel are in the best interest of our stockholders, these pursuits are costly and distracting.

There is a limited supply of desirable mineral properties available in the United States and in foreign countries where we would consider conducting exploration and/or production activities. For those that exist, we face strong competition from other mining companies, many of which have greater financial resources than we do. Therefore, we may be unable to acquire attractive companies or mining properties on terms that we consider acceptable.

Furthermore, there are inherent risks in any acquisition we may undertake which could adversely affect our current business and financial condition and our growth. For example, we may not realize the expected value of the companies or properties that are acquired due to declines in metals prices, lower than expected quality of orebodies, inability to achieve the expected or minimum level of operating performance, failure to obtain permits, labor problems, changes in regulatory environment, failure to achieve anticipated synergies, an inability to obtain financing, and other factors described in these risk factors. Acquisitions of other mining companies or properties may also expose us to new legal, geographic, political, operating, and geological risks.

See the risk factor below, “ We may not realize all of the anticipated benefits from our acquisitions, including our 2022 acquisition of Alexco. ”

We may be unable to successfully integrate the operations of the properties we acquire.

Integration of the businesses or the properties we acquire with our existing business, including the Keno Hill project acquired as part of the Alexco acquisition in September 2022, is a complex, time-consuming and costly process. Failure to successfully integrate the acquired properties and operations in a timely manner may have a material adverse effect on our business, financial condition, results of operations and cash flows. The difficulties of combining the acquired operations with our existing business include, among other things:

---

The process of integrating operations could cause an interruption of, or a slowdown in, the activities of our business. Members of our senior management may be required to devote considerable amounts of time to this integration process, which will decrease the time they will have to manage other parts of our business. If our senior management is not able to effectively manage the integration process, or if any business activities are interrupted as a result of the integration process, our business could suffer. See the risk factor below, “ We may not realize all of the anticipated benefits from our acquisitions, including our 2022 acquisition of Alexco. ”

Issues we have faced at certain segments could require us to write-down the carrying value of associated long-lived assets. We could face similar issues at our other operations. Such write-downs may adversely affect our results of operations and financial condition.

We review our long-lived assets for recoverability pursuant to the Financial Accounting Standard Board’s Accounting Standards Codification Section 360. Under that standard, we review the recoverability of our long-lived assets, such as our mining properties, upon a triggering event. Such review involves comparing an asset’s carrying value to its fair value. When the carrying value of the asset exceeds its fair value (which is based on estimating the future undiscounted cash flows expected to result from the use and eventual disposition of the asset or a market value approach), an impairment must be recognized. We conduct a review of the financial performance of our mines in connection with the preparation of our financial statements for each reporting period and determine whether any triggering events are indicated.

We identified a triggering event at Casa Berardi due to the operation's gross loss for the year ended December 31, 2024. Although we concluded the carrying value assessment indicated no impairment at the time the analysis was undertaken, each analysis was, and any future analysis will be, based on estimates, judgments and assumptions which may turn out to be incorrect or inaccurate. Though production remains suspended at our Nevada assets, we did not identify a triggering event for our Nevada long-lived assets in 2024, as our budgeted exploration program for 2025 has significantly increased compared to the level of exploration expenditures incurred in 2024.

The estimates, judgments and assumptions we use in any fair value/impairment assessment of our long-lived assets relate to factors impacting the future cash flows estimated at any of our operations, including, but not limited to: (i) metals to be extracted and recovered from proven and probable mineral reserves and, to some extent, identified mineralization beyond proven and probable reserves, (ii) future operating and capital costs, and (iii) future metals prices. These estimates, judgments and assumptions are made in good faith and using management's best judgments; however, there can be no assurance that any of them will prove to be accurate. Evaluation of the possibility of a future impairment loss, as well as the calculation of the amount of any impairment loss, involve significant estimates, judgment and assumptions, and no assurance can be given as to whether or not we will recognize an impairment loss in the future, or if the amount of loss would be within any estimated range we may disclose. As a result, in future periods we could face another triggering event which could lead to an impairment charge, and any such impairment charge could be material.

We may not realize all of the anticipated benefits from our acquisitions, including our 2022 acquisition of Alexco.

We may not realize all (or any) of the anticipated benefits from any acquisition, such as increased earnings, cost savings and revenue enhancements, for various reasons, including difficulties integrating operations and personnel, higher than expected acquisition and operating costs or other difficulties, unknown liabilities which may be significant, inaccurate reserve estimates, unrealized exploration targets, ore grades or mill recoveries that are lower than required for portions of the orebodies to be economic, and fluctuations in market prices.

At Nevada, mine production at Fire Creek continued through the first half of 2021, and was then suspended as we continue studies of hydrology, mining and milling. Revenues exceeded total capital and production costs in 2020 and 2021. However, we anticipate incurring care-and-maintenance costs in the future unless and until we have enough exploration success and development to resume mining operations. In September 2022, we completed the acquisition of Alexco and gained ownership of the Keno Hill project in the Yukon Territory, Canada. Although we produced silver at that mine in 2024, permitting and other delays and the lack of energy provided by Yukon Energy have prevented us from reaching anticipated production levels, which we estimate as 130,000 ounces during 2024. Further, the mine has required capital expenditures higher than we anticipated. As a result of the foregoing factors and their economic impacts, it is possible that we may have to suspend production and other operations at Keno Hill and place Keno Hill on care and maintenance until such time as conditions improve sufficiently to allow us to approach or reach profitability at the site.

factors above, “ An extended decline in metals prices, an increase in operating or capital costs or treatment charges, mine accidents or closures, increasing regulatory obligations, or our inability to convert resources or exploration targets to reserves may cause us to record write-downs, which could negatively impact our results of operations, ” “Certain of our mines and exploration properties are located on land that is or may become subject to traditional territory, title claims and/or claims of cultural significance, and such claims and the attendant obligations of the federal government to those tribal communities and stakeholders may affect our current and future operations,” "We may be subject to a number of unanticipated risks related to inadequate infrastructure" and “ Issues we have faced at certain segments could require us to write-down the associated long-lived assets. We could face similar issues at our other operations. Such write-downs may adversely affect our results of operations and financial condition. ”

The properties we may acquire may not produce as expected, and we may be unable to determine reserve potential, identify liabilities associated with the acquired properties or obtain protection from sellers against such liabilities.

The properties we acquire in any acquisition, including Keno Hill, may not produce as expected, may be in an unexpected condition and we may be subject to increased costs and liabilities, including environmental liabilities. Although we review properties prior to acquisition in a manner consistent with industry practices, such reviews are not capable of identifying all existing or potential adverse conditions. Generally, it is not feasible to review in depth every individual property involved in each acquisition. Even a detailed review of records and properties may not necessarily reveal existing or potential problems or permit a buyer to become sufficiently familiar with the properties to fully assess their condition, any deficiencies, and development potential. See the risk factors above, “ We may not realize all of the anticipated benefits from our acquisitions, including our 2022 acquisition of Alexco, ” “ Certain of our mines and exploration properties are located on land that is or may become subject to traditional territory, title claims and/or claims of cultural significance, and such claims and the attendant obligations of the federal government to those tribal communities and stakeholders may affect our current and future operations ” and “ An extended decline in metals prices, an increase in operating or capital costs or treatment charges, mine accidents or closures, increasing regulatory obligations, or our inability to convert resources or exploration targets to reserves may cause us to record write-downs, which could negatively impact our results of operations .”

We face risks relating to transporting our products from our mines, as well as transporting employees and materials at our Greens Creek, Casa Berardi and Keno Hill sites.

Certain of the products we ship to our customers are subject to regulatory requirements regarding shipping, packaging, and handling of products that may be considered dangerous to human health or the environment. Although we believe we are currently in compliance with all material regulations applicable to shipping, packaging, and handling our products, the chemical properties of our products or existing regulations could change and cause us to fall out of compliance or force us to incur substantial additional expenditures to maintain compliance with applicable regulations. Further, we do not ship our own products but instead rely on third party carriers to ship our products to our customers. To the extent that any of our carriers are unable or unwilling to ship our products in accordance with applicable regulations, including because of difficulty in obtaining, or increased cost of, insurance, or are involved in accidents during transit, we could be forced to find alternative shipping arrangements, assuming such alternatives would be available, and we could face liability as a result of any accident. Any such changes to our current shipping arrangements or accidents involving the shipment of our products could have a material adverse impact on our operations and financial results.

In addition, each of Greens Creek, Casa Berardi and Keno Hill are in remote locations. Greens Creek operates on an island and is substantially dependent on various forms of marine transportation for the transportation of employees and materials to the mine and for the export of its products from the mine. Further, Keno Hill requires its employees to fly in to its remote location. Casa Berardi can only be accessed by a long motor vehicle ride over a gravel road. Any disruption to these forms of marine, air and surface transportation could adversely impact mine operations, and possible effects could include suspension of operations.

Legal, Regulatory and Compliance Risks

We face substantial governmental regulation, including in the United States the Mine Safety and Health Act, various environmental laws and regulations and the 1872 Mining Law.

Our business is subject to extensive U.S. and foreign federal, state, provincial and local laws and regulations governing environmental protection, natural resources, prospecting, development, production, post-closure reclamation, taxes, labor standards and occupational health and safety laws and regulations, including mine safety, toxic substances and other matters. The costs associated with compliance with such laws and regulations are substantial. Possible future laws and regulations, or more restrictive interpretations of current laws and regulations by governmental authorities, could cause additional expense, capital expenditures, restrictions on or suspensions of operations and delays in the development of new properties.

---

U.S. mines like those at our Lucky Friday, Greens Creek and Nevada assets are inspected at least quarterly by MSHA, which inspections often lead to notices of violation under the Mine Safety and Health Act. Any of our U.S. mines could be subject to a temporary or extended shutdown as a result of a violation alleged by MSHA.

In addition, we have been and are currently involved in lawsuits or regulatory actions in which allegations have been made that we caused environmental damage, are responsible for environmental damage caused by others, or violated environmental laws or permits, and we may be subject to similar lawsuits or actions in the future. Moreover, such environmental matters have involved both our current and historical operations as well as the historical operations of entities and properties we have acquired. See the risk factors below titled “ Our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations, ” “ Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities ,” and “ Our environmental and asset retirement obligations may exceed the provisions we have made .”

We cannot assure you that we will at all times be in compliance with applicable laws, regulations and permitting requirements. Failure to comply with applicable laws, regulations and permitting requirements may result in lawsuits or regulatory actions, including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, which may require corrective measures including capital expenditures, installation of additional equipment or remedial actions. Any one or more of these liabilities could have a material adverse impact on our financial condition.

In addition to existing regulatory requirements, legislation and regulations may be adopted, regulatory procedures modified, or permit limits reduced at any time, any of which could result in additional exposure to liability, operating expense, capital expenditures or restrictions and delays in the mining, production or development of our properties. Mining accidents and fatalities or toxic waste releases, whether or not at our mines or related to metals mining, may increase the likelihood of additional regulation or changes in law or enhanced regulatory scrutiny. In addition, enforcement or regulatory tools and methods available to regulatory bodies such as MSHA or the U.S. Environmental Protection Agency (“EPA”), which have not been or have infrequently been used against us or the mining industry, in the future could be used against us or the industry in general.

From time to time, the U.S. Congress considers proposed amendments to the 1872 Mining Law, which governs mining claims and related activities on federal lands. The extent of any future changes is not known and the potential impact on us as a result of U.S. Congressional action is difficult to predict. Changes to the 1872 Mining Law, if adopted, could adversely affect our ability to economically develop mineral reserves on federal lands. For example, from time to time the U.S. Congress debates imposing royalties on minerals extracted from federal lands. Although such legislation has not passed as of the date of this report, it is possible that in the future royalties or taxes will be imposed on mining operations conducted on federal land, which could adversely impact our financial results.

Our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations. Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities.

Our operations, both in the United States and internationally, are subject to extensive environmental laws and regulations governing wastewater discharges; remediation, restoration and reclamation of environmental contamination; the generation, storage, treatment, transportation and disposal of hazardous substances; solid waste disposal; air emissions; protection of endangered and protected species and designation of critical habitats; mine closures and reclamation; and other related matters. In recent years, each of our Greens Creek, Lucky Friday, Casa Berardi and Keno Hill units have had compliance challenges and alleged violations of the Resource Conservation and Recovery Act (“RCRA”), the Clean Water Act (“CWA”) and similar Yukon regulations, respectively. Compliance challenges remain, and it is possible that we could again experience regulatory actions alleging violations of various environmental laws. For example, in May, 2023, the wall of an impoundment dam storing mixed waste material (i.e. clay, till, and rock, but not tailings or other deleterious materials) stripped during open pit mining at Casa Berardi experienced a slip resulting in the waste material being mobilized downstream. Although this incident has not yet had a material impact on operations, it could in the future, and it has caused us to begin a process that will involve analyzing all embankment structures at Casa Berardi, including their design and construction processes. Such analysis could cause us to implement embankment redesign and supplemental construction actions, which could be costly (with one estimate of $35 million if the extreme option of relocating the escaped material and the impoundment is required or chosen) . Although there has been none to date, it is possible that this incident could result in a regulatory action by federal or provincial authorities. Failure to resolve pending or avoid future alleged permit exceedances or other legal violations could have a material negative impact on operations or financial performance.

In addition for continuing our current operations, we must obtain regulatory permits, permit modifications or other approvals to start and expand operations. New or revised environmental regulatory requirements are frequently proposed, many of which result in substantially increased costs for our business. See the risk factor above, “ We are required to obtain governmental permits and other

---

approvals in order to conduct mining operations ” and the risk factor below, “ Mine closure and reclamation regulations impose substantial costs on our operations, and include requirements that we provide financial assurance supporting those obligations. These costs could significantly increase and we might not be able to provide financial assurance .”

Our U.S. operations are subject to the CWA, which requires permits for certain discharges into waters of the United States. Such permitting has been a frequent subject of litigation and enforcement activity by environmental advocacy groups and the EPA, which has resulted in declines in such permits or extensive delays in receiving them, as well as the imposition of penalties for permit violations. Adverse outcomes in lawsuits challenging permits or failure to comply with applicable regulations or permits could result in the suspension, denial, or revocation of required permits, or the imposition of penalties, any of which could have a material adverse impact on our cash flows, results of operations, or financial condition. See Note 16 of Notes to Consolidated Financial Statements .

Some of the mining wastes from our U.S. mines currently are exempt to a limited extent from the extensive set of EPA regulations governing hazardous waste under RCRA. If the EPA were to repeal this exemption, and designate these mining wastes as hazardous under RCRA, we would be required to expend additional amounts on the handling of such wastes and to make significant expenditures to construct hazardous waste storage or disposal facilities. In addition, if any of these wastes or other substances we release or cause to be released into the environment cause or has caused contamination in or damage to the environment at a U.S. mining facility, that facility could be designated as a “Superfund” site under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”). Under CERCLA, any present owner or operator of a Superfund site or the owner or operator at the time of contamination may be held jointly and severally liable regardless of fault and may be forced to undertake extensive remedial cleanup action or to pay for the cleanup efforts. The owner or operator also may be liable to federal, state and tribal governmental entities for the cost of damages to natural resources, which could be substantial. Additional regulations or requirements also are imposed on our tailings and waste disposal areas in Alaska under the CWA. See Note 16 of Notes to Consolidated Financial Statements .

Legislative and regulatory measures to address climate change and greenhouse gas emissions are in various phases of consideration. If adopted, such measures could increase our cost of environmental compliance and also delay or otherwise negatively affect efforts to obtain permits and other regulatory approvals with regard to existing and new facilities. Proposed measures could also result in increased cost of fuel and other consumables used at our operations, including the diesel generation of electricity at our Greens Creek operation, used when we are unable to access hydroelectric power. Climate change legislation may also affect our smelter customers that burn fossil fuels, resulting in fewer customers or increased costs to us, and may affect the market for the metals we produce with effects on prices that are not possible for us to predict.

Adoption of these or similar new environmental regulations or more stringent application of existing regulations may materially increase our costs, threaten certain operating activities and constrain our expansion opportunities.

Some of our facilities are located in or near environmentally sensitive areas such as salmon fisheries, endangered species habitats, wilderness areas, national monuments and national forests, and we may incur additional costs to mitigate potential environmental harm in such areas.

In addition to evolving and expanding environmental regulations providing governmental authorities with the means to make claims against us, private parties have in the past and may in the future bring claims against us based upon damage to property and injury to persons resulting from the environmental, health and safety impacts of prior and current operations (including for exposure to or contamination by lead). Laws in the U.S. such as CERCLA and similar state laws may expose us to joint and several liability or claims for contribution made by the government (state or federal) or private parties. Moreover, exposure to these liabilities arises not only from our existing but also from closed operations, operations sold to third parties, or operations in which we had a leasehold, joint venture, or other interest. Because liability under CERCLA is often alleged on a joint and several basis against any property owner or operator or arranger for the transport of hazardous waste, and because we have been in operation since 1891, our exposure to environmental claims may be greater because of the bankruptcy or dissolution of other mining companies which may have engaged in more significant activities at a mining site than we but which are no longer available for governmental agencies or other claimants to make claims against or obtain judgments from. Similarly, there is also the potential for claims against us based on agreements entered into by certain affiliates and predecessor companies relating to the transfer of businesses or properties, which contained indemnification provisions relating to environmental matters. In each of the types of cases described in this paragraph, the government (federal or state) or private parties could seek to hold us liable for the actions of our subsidiaries or predecessors.

The laws and regulations, changes in such laws and regulations, and lawsuits and enforcement actions described in this risk factor could lead to the imposition of substantial fines, remediation costs, penalties and other civil and criminal sanctions against us. Further, substantial costs and liabilities, including for restoring the environment after the closure of mines, are inherent in our operations. There is no assurance that any such law, regulation, enforcement or private claim, or reclamation activity, would not have a material adverse effect on our financial condition, results of operations or cash flows.

---

Mine closure and reclamation regulations impose substantial costs on our operations and include requirements that we provide financial assurance supporting those obligations. These costs could significantly increase and we might not be able to provide financial assurance.

We are required by U.S. federal and state laws and regulations and by laws and regulations in the foreign jurisdictions in which we operate to reclaim our mining properties. The specific requirements may change and vary among jurisdictions, but they are similar in that they aim to minimize long term effects of exploration and mining disturbance by requiring the control of possible deleterious effluents and re-establishment to some degree of pre-disturbance land forms and vegetation. In some cases, we are required to provide financial assurances as security for reclamation costs, which may exceed our estimates for such costs. Similarly, our reclamation costs may exceed the financial assurances in place and those assurances may ultimately be unavailable to us. We often satisfy financial assurance requirements by posting surety bonds or cash collateral however, we may be unable to obtain the required surety bonds or may not have the resources to provide cash collateral, and the bonds or collateral may not fully cover the cost of reclamation and any such shortfall could have a material adverse impact on our financial condition. Further, when we use the services of a surety company to provide the required bond for reclamation, the surety companies often require us to post collateral with them. Currently we utilize letters of credit issued under our revolving credit facility as the source of such collateral, and as a result, there are less funds available for us to borrow under the facility for other purposes. In the event that we are unable to obtain necessary bonds or to post sufficient collateral, we may experience a material adverse effect on our operations or financial results. See the risk factors below, “Our existing stockholders are effectively subordinated to the holders of our Senior Notes", “Any downgrade in the credit ratings assigned to us or our debt securities could increase future borrowing costs, adversely affect the availability of new financing and may result in increased collateral requirements under our existing surety bond portfolio,” and “Mine closure and reclamation regulations impose substantial costs on our operations, and include requirements that we provide financial assurance supporting those obligations. These costs could significantly increase, and we might not be able to provide financial assurance.”

The EPA and other state, provincial or federal agencies may also require financial assurance for investigation and remediation actions that are required under settlements of enforcement actions under CERCLA or equivalent state or foreign regulations. Currently there are no financial assurance requirements for active mining operations under CERCLA, and a lawsuit filed by several environmental organizations which sought to require the EPA to adopt financial assurance rules for mining companies with active mining operations was dismissed by a federal court. In the future, financial assurance rules under CERCLA, if adopted, could be financially material and adverse to us. See the risk factors, “ Our operations are subject to complex, evolving and increasingly stringent environmental laws and regulations. Compliance with environmental regulations, and litigation based on such regulations, involves significant costs and can threaten existing operations or constrain expansion opportunities ” and “ We are required to obtain governmental permits and other approvals in order to conduct mining operations .”

We are required to obtain governmental permits and other approvals in order to conduct mining operations.

In the ordinary course of business, mining companies are required to seek governmental permits and other approvals for continuation or expansion of existing operations or for the commencement of new operations. Obtaining the necessary governmental permits is a complex, time-consuming and costly process. The duration and success of our efforts to obtain permits are contingent upon many variables not within our control. Obtaining environmental permits, including the approval of reclamation plans, may increase costs and cause delays or halt the continuation of mining operations depending on the nature of the activity to be permitted and the interpretation of applicable requirements established by the permitting authority. Interested parties, including governmental agencies and non-governmental organizations or civic groups, may seek to prevent issuance of permits and intervene in the process or pursue extensive appeal rights. Past or ongoing violations of laws or regulations involving obtaining or complying with permits could provide a basis to revoke existing permits, deny the issuance of additional permits, or commence a regulatory enforcement action, each of which could have a material adverse impact on our operations or financial condition. In addition, evolving reclamation or environmental concerns may threaten our ability to renew existing permits or obtain new permits in connection with future development, expansions and operations. We cannot assure you that all necessary approvals and permits will be obtained and, if obtained, that the costs involved will not exceed those that we previously estimated. It is possible that the costs and delays associated with the compliance with evolving standards and regulations could become such that we would not proceed with a particular development or operation.

Specific examples of where we face permitting risk include the following:

---

See the risk factors above, “ Certain of our mines and exploration properties are located on land that is or may become subject to traditional territory, title claims and/or claims of cultural significance, and such claims and the attendant obligations of the federal government to those tribal communities and stakeholders may affect our current and future operations ” and “ Legal challenges could prevent our projects in Montana from ever being developed .”

We are currently involved in ongoing legal disputes that may materially adversely affect us.

There are several ongoing legal disputes in which we are involved, including a putative class action lawsuit filed against us and certain current and former directors and officers involving our Nevada Operations. Further, we have experienced in the past, and could experience in the future, claims regarding environmental damage or compliance, safety conditions or other matters at our mines. The outcomes of these pending and potential claims are uncertain. We may not resolve these claims favorably. Depending on the outcome, these actions could cause adverse financial effects or reputational harm to us. If any of these disputes result in a substantial monetary judgment against us, are settled on terms unfavorable to us, or otherwise impact our operations (such as by limiting our ability to obtain permits or approvals), our financial results or condition could be materially adversely affected. For a description of some of the lawsuits and other claims in which we are involved, see Note 16 of Notes to Consolidated Financial Statements .

Our environmental and asset retirement obligations may exceed the provisions we have made.

We are subject to significant environmental obligations. At December 31, 2024, we had accrued $124.9 million as a provision for environmental and asset retirement obligations. We cannot assure you that we have accurately estimated these obligations, and in the future our accrual could materially change and we could voluntarily incur expenditures in excess of our accrual. Our environmental and asset retirement obligations and voluntary expenditures could have a material adverse impact on our cash flows, results of operations, or financial condition. For information on our potential environmental liabilities and asset retirement obligations, see Note 5 and Note 16 of Notes to Consolidated Financial Statements .

New federal and state laws, regulations and initiatives could impact our operations.

In recent years there have been several proposed or implemented ballot initiatives that sought to directly or indirectly curtail or eliminate mining in certain states, including Alaska, where our Greens Creek mine operates, and Montana, where we are seeking to explore at the Libby Exploration project, and possibly develop depending on the results of exploration activities, and may in the future seek to explore or develop the Rock Creek project. While both a salmon initiative in Alaska and a water treatment initiative in Montana were defeated by voters in November 2018, in the future similar or other initiatives that could impact our operations may be on the ballot in these states or other jurisdictions (including local or international) in which we currently or may in the future operate. To the extent any such initiative was passed and became law, there could be a material adverse impact on our financial condition, results of operations or cash flows.

---

Legal challenges could prevent our projects in Montana from ever being developed.

A joint final Environmental Impact Statement with respect to the Libby Exploration project in Montana was issued in December 2015 by the USFS and the Montana Department of Environmental Quality (“DEQ”), and each agency issued a Record of Decision (“ROD”) in February 2016 providing approval for development of the Libby project. However, private conservation groups have taken and may in the future take actions to oppose or delay activities at the Libby project. On May 30, 2017, the Montana Federal District Court issued Opinions and Orders in three lawsuits challenging previously granted environmental approvals for the Libby project. The Orders overturned the approvals for the project granted by the USFS and the United States Fish and Wildlife Service (“USFWS”), and in each case remanded the ROD and associated planning documents for further review by the agencies consistent with the Court’s Opinions. In June 2017, the Court vacated the agencies’ approvals for the project. In addition, the Libby project's updated water discharge permit under Montana law was found to be invalid by the Montana Supreme Court in November 2020. As a result, the site is operating under the previously issued permit as authorized by law, while a new permit is pending.

In 2022, our subsidiary withdrew the Plan of Operations for the Libby Exploration project from USFS consideration and submitted a new Plan of Operations proposing only underground exploration and evaluation activities at the site. In conjunction with this narrower scope of activity, the USFS withdrew its previously issued Supplemental Environmental Impact Statement (“SEIS”). The proposed exploration activities are currently undergoing an Environmental Assessment under the National Environmental Policy Act (NEPA).

The proposed development of our Rock Creek site, also located in Montana, has been challenged by several regional and national conservation groups at various times since the USFS issued its initial ROD in 2003 approving Revett Mining Company’s plan of operation (Revett is now our wholly-owned subsidiary, named Hecla Montana, Inc.). In February 2022, our subsidiary withdrew the Plan of Operations for Rock Creek from USFS consideration. Nonetheless, we report inferred mineral resources at Rock Creek below in Item 2. Properties and we expect that should we resume permitting at that project, it would again be met with litigation by non-governmental organizations.

As a result of the legal challenges and other circumstances related to our Montana projects, we are now focused on obtaining the permits necessary to conduct underground exploration and evaluation activities at the Libby Exploration site and are not currently engaged in permitting activities for Rock Creek. Generally speaking, permitting has been delayed and further delays are likely, along with increased costs, and ultimately, we may be prevented from ever fully permitting or exploring or developing a project at either of the two sites.

The titles to some of our properties may be defective or challenged.

Unpatented mining claims constitute a significant portion of our undeveloped property holdings in the United States. For our operations in Canada and Mexico, we hold mining claims, mineral concession titles and mining leases that are obtained and held in accordance with the laws of the respective countries, which provide us the right to exploit and explore the properties. The validity of the claims, concessions and leases could be uncertain and may be contested. Although we have conducted title reviews of our property holdings, title review does not necessarily preclude third parties (including governments) from challenging our title. In accordance with mining industry practice, we do not generally obtain title opinions until we decide to develop a property. Therefore, while we have attempted to acquire satisfactory title to our undeveloped properties, some titles may be defective.

Risks Relating to Our Common Stock and Our Indebtedness

We may be unable to generate sufficient cash to service all of our debt and meet our other ongoing liquidity needs and may be forced to take other actions to satisfy our obligations, which may be unsuccessful.

Our ability to make scheduled payments or to refinance our debt obligations and to fund our planned capital expenditures and other ongoing liquidity needs depends on our financial and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. There can be no assurance that our business will generate sufficient cash flow from operations or that borrowings will be available to us to pay the principal, premium, if any, and interest on our debt or to fund our other liquidity needs. Throughout a significant portion of 2024, we were in a negative cash position, which means the cash and cash equivalents disclosed on our consolidated balance sheets, was the result of borrowings under our revolving credit facility. Absent price increases for the metals we produce or financing transactions such as asset sales or equity offerings, including under our “at-the-market” ("ATM") equity program, it is likely that we will be in a negative cash position at various time throughout 2025, and we will be dependent on borrowings under our revolving credit facility for our cash and cash equivalents balance on our consolidated balance sheet to be positive. See the below risk factor “ The terms of our debt impose restrictions on our operations. ” We may need to refinance all or a portion of our debt on or before maturity. We may be unable to refinance any of our debt on commercially reasonable terms or at all.

---

In addition, we conduct substantially all of our operations through our subsidiaries. Accordingly, repayment of our debt is dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, debt repayment or otherwise. Certain of our subsidiaries are not guarantors of our debt and thus do not have any obligation to pay amounts due on our debt or to make funds available for that purpose. Our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our debt. Each subsidiary is a distinct legal entity and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. While the credit agreement governing our revolving credit facility and the indenture governing our Senior Notes limit the ability of our subsidiaries to incur consensual restrictions on their ability to pay dividends or make other intercompany payments to us, these limitations are subject to qualifications and exceptions. In the event that we do not receive distributions from our subsidiaries, we may be unable to make required principal and interest payments on our debt.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments, capital expenditures and exploration efforts or to sell assets, seek additional capital or restructure or refinance our debt. Our ability to restructure or refinance our debt will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The terms of existing or future debt instruments and the indenture governing our Senior Notes may restrict us from adopting some of these alternatives. Further, these alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. In addition, any failure to make payments of interest and principal on our outstanding debt on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional debt.

The price of our stock has a history of volatility and could decline in the future.

Shares of our common and outstanding preferred stock are listed on the New York Stock Exchange (“NYSE”). The market price for our stock has been volatile, often based on:

The market price of our stock at any given point in time may not accurately reflect our value, and may prevent stockholders from realizing a profit on, or recovering, their investment.

We may not be able to pay common or preferred stock dividends in the future.

Since January 2010, we have paid all regular quarterly dividends on our Series B preferred stock. The annual dividend payable on the Series B preferred stock is currently $0.6 million. Prior to 2010, there were numerous occasions when we did not declare dividends

---

on the Series B Preferred Stock, but instead deferred them. We cannot assure you that we will continue to pay preferred stock dividends in the future.

Our Board of Directors adopted a common stock dividend policy that has two components: (1) a dividend that links the amount of dividends on our common stock to our average quarterly realized silver price in the preceding quarter, and (2) a minimum annual dividend of $0.015 per share of common stock, in each case payable quarterly, when declared. See Note 12 of Notes to Consolidated Financial Statements for more information on our common stock dividend policy.

From the fourth quarter of 2011 through and including the fourth quarter of 2024, our Board of Directors has declared a common stock dividend under the policy described above. The declaration and payment of common stock dividends, whether pursuant to the policy or in addition thereto, is at the sole discretion of our Board of Directors, and we cannot assure you that we will continue to declare and pay common stock dividends in the future, and our Board of Directors make revise or revoke the current common stock dividend policy at any time and without advance notice. In addition, the indenture governing our Senior Notes limits our ability to pay dividends.

Our existing stockholders are effectively subordinated to the holders of our Senior Notes.

In the event of our liquidation or dissolution, stockholders’ entitlement to share ratably in any distribution of our assets would be subordinated to the holders of our Senior Notes. Any rights that a stockholder may have in the event of bankruptcy, liquidation or a reorganization of us or any of our subsidiaries, and any consequent rights of stockholders to realize on the proceeds from the sale of any of our or our subsidiaries’ assets, will be effectively subordinated to the claims of the holders of our Senior Notes.

The issuance of additional shares of our preferred or common stock in the future could adversely affect holders of common stock.

The market price of our common stock may be influenced by any preferred or common stock we may issue. Our Board of Directors is authorized to issue additional classes or series of preferred stock without any action on the part of our stockholders. This includes the power to set the terms of any such classes or series of preferred stock that may be issued, including voting rights, dividend rights and preferences over common stock with respect to dividends or upon the liquidation, dissolution or winding up of the business and other terms. If we issue preferred stock in the future that has preference over our common stock with respect to the payment of dividends or upon liquidation, dissolution or winding up, or if we issue preferred stock with voting rights that dilute the voting power of our common stock, the rights of holders of the common stock or the market price of the common stock could be adversely affected.

The provisions in our certificate of incorporation, our by-laws and Delaware law could delay or deter tender offers or takeover attempts.

Certain provisions in our restated certificate of incorporation, our by-laws and Delaware law could make it more difficult for a third party to acquire control of us, even if that transaction could be beneficial to stockholders. These impediments include:

---

In addition, amendment of most of the provisions described above requires approval of at least 80% of the outstanding voting stock.

The terms of our debt impose restrictions on our operations.

The indenture governing our Senior Notes includes several significant covenants. These covenants could adversely affect us by limiting our ability to plan for or react to market conditions or to meet our capital needs. These covenants, among other things:

These restrictions may affect our ability to grow in accordance with our strategy. Further, our financial results, our substantial indebtedness and our credit ratings could adversely affect the availability and terms of any financing.

In addition, our revolving credit facility requires us to comply with various covenants, including certain financial ratios, that restrict management’s discretion to operate our business in certain circumstances. For example, these restrictions include limitations that could affect our ability to incur additional indebtedness, place liens or mortgages on our assets, sell assets or release collateral. These restrictions could make it more difficult for us to obtain additional financing or take advantage of business opportunities. Furthermore, a breach of any of these covenants could result in an event of default under the agreement governing our revolving credit facility that, if not cured or waived, could give our lenders the right to terminate commitments to lend and cause all amounts outstanding with respect to the debt to be due and payable immediately. Acceleration of any of our debt could result in cross-defaults under our other debt instruments, including the indenture governing our Senior Notes, as well as certain forward sales contracts which may be outstanding from time to time. Our assets and cash flow may be insufficient to repay borrowings fully under all of our outstanding debt instruments if any of our debt instruments are accelerated upon an event of default, which could force us into bankruptcy or liquidation. In such an event, we may be unable to repay our debt obligations. In addition, in some instances, this would create an event of default under the indenture governing our Senior Notes.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our indebtedness service obligations to increase significantly.

Borrowings under our credit facility are at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our indebtedness, would correspondingly decrease. Assuming all revolving loans currently available to us were fully drawn, each one percentage point change in interest rates would result in a $2.2 million change in annual cash interest expense on our credit facility.

General Risk Factors

---

Global financial events or developments impacting major industrial or developing countries may have an impact on our business and financial condition in ways that we currently cannot predict.

The COVID-19 pandemic and 2008 credit crisis and related turmoil in the global financial system and ensuing recession had an impact on our business and financial position, and similar events in the future could also impact us. The re-emergence of a financial crisis or recession or reduced economic activity in the United States, China, India and other industrialized or developing countries, or disruption of key sectors of the economy such as oil and gas, may have a significant effect on our results of operations or limit our ability to raise capital through credit and equity markets. The prices of the metals that we produce are affected by a number of factors, and it is unknown how these factors may be impacted by a global financial event or developments impacting major industrial or developing countries.

Tariffs, other potential changes to tariff and import/export regulations, or trade disputes between the United States and other jurisdictions may have a negative effect on global economic conditions and on our business, financial results and financial condition.

Starting in 2018, and continuing to today, the United States imposed tariffs on certain items imported from certain countries, including China and Canada (as discussed below). In response, a number of markets, including China - where we have in the past and may in the future sell our products - have implemented tariffs on U.S. imports, or have threatened to impose tariffs on U.S. imports or to take other measures in response to these U.S. trade actions. These developments may have a material adverse effect on global economic conditions and the stability of global financial markets, and they may significantly reduce global trade and, in particular, trade between China and the United States. Any of these factors could depress economic activity, impact U.S. dollar/foreign currency exchange rates (which we are subject to), restrict our access to customers and have a material adverse effect on our business, financial condition and results of operations. In addition, any actions by foreign markets to implement further trade policy changes, including limiting foreign investment or trade, increasing regulatory scrutiny or taking other actions which impact U.S. companies’ ability to obtain necessary licenses or approvals could negatively impact our business.

In September 2018, in response to tariffs on Chinese goods implemented by the United States, China imposed a 10% tariff on lead concentrates and a 20% tariff on silver concentrates, which we produce and ship to China from time to time. However, tariff exemptions were granted to a number of smelters in China in 2024, 2023 and 2022, and we sold silver concentrates to China representing approximately 20%, 15%, and 19% of our total metals sales for 2024, 2023 and 2022, respectively. These sales were not subject to Chinese tariffs due to the exemptions. While to date the direct impact of tariffs has been immaterial on our sales and treatment charges, they could have an impact on our sales and treatment charges outside of China, and there can be no assurance that the Chinese tariff exemptions will continue.

Since beginning his second term in office on January 20, 2025, President Trump has announced new tariffs on China and Canada, another nation where we sell our products. In response, both countries adopted retaliatory tariffs on goods imported from the U.S. Subsequently, both Canada and the U.S. have delayed the implementation of their respective tariffs. We do not believe that the recently announced Chinese tariffs affect our products, but the situation is fluid and products that we have in the past and may in the future ship to China, could be subject to new tariffs which, absent applicable exemptions, could have a material adverse impact on our business, financial condition and results of operations. Further, any materials that we import to the U.S. from countries subject to tariffs, could become more expensive if subject to a tariff, which could also have a material adverse impact on our business, financial condition and results of operations

Our profitability could be affected by inflation, including the prices of other commodities.

Our profitability is sensitive to cost inflation, including, but not limited to the costs of commodities such as fuel (in particular as used at Greens Creek to generate electricity when hydropower is unavailable, as is the case from time to time, particularly in periods with low precipitation), steel, and cement, as well as other consumables and labor. Recently the prices we pay for commodities and consumables have increased which has increased the operating costs at our mine sites. In addition, labor costs have increased, including under the terms of our new labor agreement with the union at the Lucky Friday mine. Increased or persistent inflation or other upward pressures could continue to increase our costs, and could have a material impact on our results of operations.

Our business depends on availability of skilled miners and good relations with employees.

We are dependent upon the ability and experience of our executive officers, managers, employees, contractors and their employees, and other personnel, and we cannot assure you that we will be able to retain such employees or contractors. We compete with other companies both in and outside the mining industry in recruiting and retaining qualified employees and contractors knowledgeable about the mining business. From time to time, we have encountered, and may in the future encounter, difficulty recruiting skilled mining personnel at acceptable wage and benefit levels in a competitive labor market, and may be required to utilize contractors, which can be more costly. Temporary or extended lay-offs due to mine closures may exacerbate such issues and result in vacancies or

---

the need to hire less skilled or efficient employees or contractors. The loss of skilled employees or contractors or our inability to attract and retain additional highly skilled employees and contractors could have an adverse effect on our business and future operations.

We or our contractors may experience labor disputes, work stoppages or other disruptions in production that could adversely affect our business and results of operations. Currently, the Lucky Friday mine is our only operation where some of our employees are subject to a collective bargaining agreement, however, there have been union organizing efforts at our other operations. The unionized employees at Lucky Friday were on strike from March 13, 2017 until January 7, 2020, when the union ratified a new collective bargaining agreement (“CBA”), which expired on January 6, 2023 (a new six year CBA was approved by the union in January 2023). The strike significantly impacted production at the Lucky Friday and caused significant costs and expenses during each year of the strike. Any future strikes or other labor or related disruptions could adversely affect our financial condition and results of operations.

Our information technology systems may be vulnerable to disruption which could place our systems at risk from data loss, operational failure, or compromise of confidential information.

We rely on various information technology systems and on third party developers and contractors in connection with operations, including production, equipment operation and financial support systems. While we regularly monitor the security of our systems, they remain vulnerable to disruption, damage or failure from a variety of sources, including errors by employees or contractors, computer viruses, cyber-attacks including phishing, ransomware and similar malware, misappropriation of data by outside parties, and various other threats all of which have been amplified through the proliferation of artificial intelligence ("AI"), particularly generative AI. In particular, we use cloud systems which could be vulnerable to external intrusions. Techniques used to obtain unauthorized access to or sabotage our systems are under continuous and rapid evolution, and we may be unable to detect efforts to disrupt our data and systems in advance. Breaches and unauthorized access carry the potential to cause losses of assets or production, operational delays, equipment failure that could cause other risks to be realized, inaccurate recordkeeping, or disclosure of confidential information, any of which could result in financial losses and regulatory or legal exposure, and could have a material adverse effect on our cash flows, financial condition or results of operations.

We could also be adversely affected by system or network disruptions due to disasters or if new or upgraded information technology systems are defective, not installed properly or not properly integrated into our operations. For example, we are in the process of migrating to a new enterprise resource planning (“ERP”) software platform which we ultimately expect will improve our operational efficiency. However, the project is complex, time-consuming and costly, and there is no assurance we will efficiently or successfully implement the new ERP platform. Additionally, disaster recovery failure or system modification failures could have a material adverse effect on our business, financial position and results of operations and could, if not successfully implemented, adversely impact the effectiveness of our internal controls over financial reporting.

Competition from other mining companies may harm our business.

We compete with other mining companies, some of which have greater financial resources than we do or other advantages, in various areas which include:

Additional issuances of equity securities by us would dilute the ownership of our existing stockholders and could reduce our earnings per share.

We may issue securities in the future in connection with raising capital, acquisitions, strategic transactions or for other purposes. To the extent we issue any additional equity securities (or securities convertible into equity), the ownership of our existing stockholders would be diluted and our earnings per share could be reduced.

---

If a large number of shares of our common stock are sold in the public market, the sales could reduce the trading price of our common stock and impede our ability to raise future capital.

We cannot predict what effect, if any, future issuances by us of our common stock or other equity will have on the market price of our common stock. Any shares that we may issue may not have any resale restrictions, and therefore could be immediately sold by the holders. The market price of our common stock could decline if certain large holders of our common stock, or recipients of our common stock, sell all or a significant portion of their shares of common stock or are perceived by the market as intending to sell these shares other than in an orderly manner. In addition, these sales could also impair our ability to raise capital through the sale of additional common stock in the capital markets.

Any downgrade in the credit ratings assigned to us or our debt securities could increase future borrowing costs, adversely affect the availability of new financing and may result in increased collateral requirements under our existing surety bond portfolio.

As of February 7, 2025, our Senior Notes were rated “BB-” by Standard & Poor’s and “B2” by Moody’s Investors Service. We cannot assure you that any rating currently assigned by Standard & Poor’s or Moody’s to us or our debt securities (including the Senior Notes) will remain unchanged for any given period of time or that a rating will not be lowered if, in that rating agency’s judgment, future circumstances relating to the basis of the rating so warrant. If we are unable to maintain our outstanding debt and financial ratios at levels acceptable to the credit rating agencies, or should our business prospects or financial results deteriorate, including as a result of declines in silver and gold prices or other factors beyond our control, our ratings could be downgraded by the rating agencies. Downgrading the credit rating of our debt securities or placing us on a watch list for possible future downgrading would likely adversely impact us, including our ability to obtain financing on favorable terms, if at all, increase borrowing costs, result in increased collateral requirements under our surety bond portfolio, and have an adverse effect on the market price of our securities, including our Senior Notes.

Damage to our reputation may result in decreased investor confidence, challenges in maintaining positive community relations and can pose additional obstacles to our ability to develop our projects, which may result in a material adverse impact on our business, financial position, results of operations and growth prospects.

Damage to our reputation can be the result of the actual or perceived occurrence of a variety of events and circumstances, and could result in negative publicity (for example, with respect to handling of environmental, safety and security matters, dealings with local community organizations or individuals, community commitments, handling of cultural sites or resources, and various other matters).

We have also provided greater transparency on environmental, social and governance performance in response to stakeholder engagement and requests in recent years, and provide supplemental disclosures in our annual Sustainability Report and other sustainability reports on our website in connection with stakeholder concerns and issues. Such increased transparency may result in greater scrutiny and impact how we are perceived.

The growing use of social media to generate, publish and discuss community news and issues and to connect with others has made it significantly easier, among other things, for individuals and groups to share their opinions of us and our activities, whether true or not. We do not have direct control over how we are perceived by others and any resulting loss of reputation could have a material adverse effect on our business, financial position and results of operations.

Greens Creek is within the Admiralty Island National Monument, an environmentally sensitive area. The Greens Creek property includes 440 unpatented lode mining claims, 58 unpatented millsite claims, 21 patented lode claims and one patented millsite. In addition, the Greens Creek site includes properties under lease from the USFS for a road right-of-way, mine waste area and tailings storage facility. The USFS leases have varying expiration terms. Greens Creek also has title to mineral rights on 7,301 acres of federal land acquired through a land exchange with the USFS. We are currently exploring, but not mining, on such federal land. The claims and leases above comprise a total area of approximately 24 square miles.

The Greens Creek deposit is a volcanogenic massive sulfide deposit with a relatively high precious metal content compared to other deposits of its type. The host rock consists predominantly of marine sedimentary and mafic to ultramafic volcanic and plutonic rocks, which have been subjected to multiple periods of deformation. These deformational episodes imposed intense tectonic fabrics and folds within the rock. The deposits occur at the contact between Mississippian-age mafic meta-volcanic footwall and a hanging wall of Triassic-age argillite and basalt. Extensive hydrothermal alteration occurred within the meta-volcanic footwall prior to and during ore deposition, converting the basalts to sericite-rich, phyllitic schist. At ore deposition, thick and extensive lenses of base and precious metals, with pyrite and barite, formed at the footwall-hanging wall contact. Major sulfide minerals include pyrite, sphalerite, galena, and tetrahedrite/tennantite.

Greens Creek consists of the mine, an ore concentrating mill, a tailings storage area, a ship-loading facility, camp facilities, a ferry dock, and other related infrastructure. The map below illustrates the location and access to Greens Creek:

Greens Creek is an underground mine accessed by a ramp from surface which produces approximately 2,300 to 2,600 tons of ore per day. The primary mining methods are cut and fill and longhole stoping. The Greens Creek ore processing facility includes a SAG/ball mill grinding circuit to grind the run of mine ore to liberate the minerals and produce a slurry suitable for differential flotation of mineral concentrates. A gravity circuit recovers free gold that exists as electrum, a gold/silver alloy in the ore. Gravity concentrates are produced from this circuit prior to flotation. Three flotation concentrates are produced: a silver concentrate which contains most of the silver recovered; a zinc concentrate which is low in precious metals content; and a zinc-rich precious metals concentrate that contains gold, silver, zinc, and lead and must be marketed to a smelter utilizing an Imperial Smelting Furnace (ISF) which can simultaneously produce both zinc and lead. Doré is produced from the gravity concentrate by a third-party processor and further refined and sold to precious metal traders. The concentrate products are sold to a number of smelters and traders worldwide. See Note 4 of Notes to Consolidated Financial Statements for information on the significant customers for Greens Creek’s products. Concentrates are shipped from the Hawk Inlet marine terminal about nine miles from the mill.

Lucky Friday

We have owned and operated the Lucky Friday mine since 1958, which we have wholly owned since 1964. Lucky Friday is a deep underground silver, lead and zinc mine located in the Coeur d’Alene Mining District in northern Idaho at 47°28'15.70”N Latitude, 115°47'0.44”W Longitude (WGS84). Lucky Friday is one-quarter mile east of Mullan, Idaho, and is adjacent to U.S. Interstate 90. We report Lucky Friday as a separate segment in our consolidated financial statements. See Note 4 of Notes to Consolidated Financial Statements and Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations - Lucky Friday for information on its financial performance.

The Lucky Friday mine is comprised of 710 acres consisting of 43 patented mining claims and fee lands and 535 acres consisting of 53 unpatented mining claims. We also own or control approximately 26 square miles of mineral interests, which include patented mining and millsite claims, fee lands, and unpatented mining claims, that are adjacent to the Lucky Friday mine property. Below is a map illustrating the location and access to Lucky Friday:

The principal mineral-bearing structure at the Lucky Friday Mine through 1997 was the Lucky Friday Vein, a fissure vein typical of many in the Coeur d’Alene Mining District. The Revett Formation (quartzite) of late Precambrian age hosts the productive portion of the vein. The Lucky Friday Vein strikes northeast and dips nearly vertical with an average width of six to seven feet. Its principal ore minerals are galena and tetrahedrite with minor amounts of sphalerite and chalcopyrite. The ore occurs as a single, continuous ore zone in, and along the Lucky Friday Vein. In 1991, Hecla discovered several mineralized veins containing some high-grade silver ores in the Gold Hunter property, located about 5,000 feet northwest of the Lucky Friday Vein workings. Hecla finished a feasibility study in 1997 and achieved full production in 1998. The Gold Hunter veins are hosted in a 200-foot-thick siliceous lens within the Wallace Formation (quartzite, limestone, and argillite) that transitions to the St Regis Formation (quartzite and argillite) below the 5900-level. The veins are sub-parallel, and perhaps ‘en-echelon’ along strike and dip. The strike of the vein system is west-northwest with a dip of 85 degrees to the south. While the veins share many characteristics with the Lucky Friday Vein, there are some mineralogical and rock mechanics differences that currently make mining at Gold Hunter more attractive.

Access to the mining horizons from the surface is by shaft access. Once underground, trackless drifts and ramps are utilized to reach the mining areas. An internal, hoisting shaft was completed in 2017 to extend access at depth in the Gold Hunter area. The principal mining methods in use at Lucky Friday consist of underhand systems with integral paste fill and varying degrees of mechanization. In 2021, we tested and implemented the underhand closed bench ("UCB") mining method. The UCB method is a new and patented productive mining method developed by Hecla for proactive control of fault-slip seismicity in deep, high-stress, narrow-vein mining. The method uses bench drilling and blasting methods to fragment significant vertical and lateral extents of the vein beneath a top cut taken along the strike of the vein and under engineered backfill. The method is accomplished without the use of drop raises or lower mucking drives which may result in local stress concentrations and increased exposure to seismic events. Large blasts using up to 35,000 lbs. of pumped emulsion and programmable electronic detonators fragment up to 350 feet of strike length to a depth of approximately 30 feet. These large blasts proactively induce fault-slip seismicity at the time of the blast and shortly after it. This blasted corridor is

then mined underhand for two cuts. As these cuts are mined, little to no blasting is done to advance them. Dilution is controlled by supporting the hanging wall and footwall as the mining progresses through the blasted ore. The entire cycle repeats and stoping advances downdip, under fill, and in a destressed zone. The method allows for greater control of fault-slip seismic events significantly improving safety. In conjunction, a notable productivity increase has been achieved by reducing seismic delays and utilizing bulk mining activities. In 2024, 2023 and 2022, 86%, 87% and 88%, respectively of the tons mined were produced through the UCB method. The underhand cut and fill method was also utilized in 2024, 2023 and 2022. Under this method, once a cut is taken along the strike of the vein, it is backfilled with cemented tailings and the next cut is accessed below from the ramp system. Both methods utilize rubber-tired equipment to access the veins through ramps developed outside of the ore body.

Ore at Lucky Friday is processed using a conventional lead/zinc flotation flowsheet, and the plant capacity currently is estimated at 1,165 tons per day. During August 2023, the production at the mine was suspended due to a fire that occurred while repairing an unused station in the #2 ventilation shaft, which is also the secondary egress (required by MSHA regulations). By early September, the fire had been extinguished, normal ventilation was reestablished and the workforce recalled. Following evaluation of alternatives, it was determined that in order to safely bring the mine back into production in the most rapid and cost-effective way, a new secondary egress needed to be developed to bypass the damaged portion of the #2 shaft. The new egress involved extending an existing ramp 1,600 feet, installing a 290-foot-long manway raise, and developing an 850-foot ventilation raise. This work resulted in operations being suspended for the remainder of 2023, with the mine restarting production on January 9, 2024, and ramping up to full production during the first quarter.

For more information, see Exhibit 96.2, the Technical Report Summary on the Lucky Friday Mine, Idaho, U.S.A., prepared for the Company by the QP, SLR, with an effective date of December 31, 2021.

At December 31, 2024, there were 431 employees at Lucky Friday. The United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial, and Service Workers International Union is the bargaining agent for Lucky Friday’s 323 hourly employees as of December 31, 2024. During early January 2023, the bargaining agent ratified a six-year labor agreement that expires in May 2029. Following a strike that started in March 2017 and ended in early January 2020, re-staffing of the mine and ramp-up activities were completed during 2020, with a return to full production starting in the fourth quarter of 2020.

As of December 31, 2024, we have recorded a $11.0 million asset retirement obligation for reclamation and closure costs. The net book value of the Lucky Friday property and its associated plant, equipment and mineral interests was approximately $559.0 million as of December 31, 2024. The vintage of the facilities at Lucky Friday ranges from the 1950s to 2024.

K eno Hill

The Keno Hill unit is located in the central Yukon Territory, Canada, and covers an area of approximately 15,000 hectares (37,000 acres) in central Yukon (63° 54' 32" N, 135° 19’ 18” W; NTS 105M/14 and 105M/13). The operations are located in the traditional territory of the First Nation of Na-Cho Nyäk Dun (FNNND). We report Keno as a separate segment in our consolidated financial statements. See Note 4 of Notes to Consolidated Financial Statements and Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations - Keno Hill for information on its financial performance.

The total Hecla Keno Hill mineral claims as of December 31, 2024, covers an area of 238.12 square kilometers (92 square miles) and comprises 717 quartz mining leases, 867 quartz mining claims and two Crown Grants. Below is a map illustrating the location and access to Keno Hill:

The Keno Hill property is a polymetallic silver-lead-zinc vein district with characteristics similar to other well-known mining districts in the world. Examples of this type of mineralization include the Kokanee Range (Slocan), British Columbia; Coeur d’Alene, Idaho; Freiberg and the Harz Mountains, Germany; and Príbram, Czech Republic.

The local geology is dominated by the Mississippian Keno Hill Quartzite comprising the Basal Quartzite Member and conformably overlying Sourdough Hill Member. Silver predominantly occurs in argentiferous galena and argentiferous tetrahedrite (freibergite). In some assemblages, silver is also found as native silver, in polybasite, stephanite, and pyrargyrite. Lead occurs in galena and zinc in sphalerite. Other sulfides include pyrite, pyrrhotite, arsenopyrite, and chalcopyrite. In general, common gangue minerals include siderite and, to a lesser extent, quartz, and calcite.

Keno Hill ore is mined with a mechanized cut and fill method ("MCF"). Where the ore width is wider than can be safely extracted in one cut, the ore will be mined in adjacent drifts. Lenses are predominantly mined in a bottom-up sequence and filled with cemented rock fill ("CRF") with a 3%-8% binder content. CRF is used to introduce temporary sill levels or to fill initial drifts when multiple adjacent drifts are required. Temporary sill levels form a sequence interrupting pillar which allows for multiple mining fronts to be active on one lens at a time. The remainder of the lifts will be backfilled with unconsolidated rock fill ("URF"). This mining method was chosen due to the narrow steeply dipping nature of the mineral bodies and to maximize safety and productivity. The various deposits require the use of mining methods that can adequately support the vein and that are flexible and selective while minimizing the direct mining costs. In the MCF method, an attack ramp is developed from the main ramp at a gradient of -15%. Upon reaching the orebody, an intersection is developed, and a lift is developed in both directions along strike, following the geological contact of the orebody. At the end of the lens, the void is backfilled using a Load Haul Dump ("LHD") machine. The LHD utilizes a bulldozer-like plate to push waste tight to the back of the drift. Once the level has been completely backfilled, the next lift above the previously mined lift is accessed by slashing down the back of the attack ramp and working off the muck pile/horizon. MCF drift sizes are on average 3.5 meters high x 3.5 meters wide. For areas wider than development equipment, a second parallel drift will be mined beside the backfilled drift to fully extract the material prior to accessing the lift above. In this situation, the first drift will be completely backfilled with cemented rock fill to ensure a stable wall to allow adjacent mining activity. The lifts are generally sequenced from the bottom-up within each panel.

The Keno Hill mill is based on a conventional sequential flotation process producing silver and zinc concentrates. The silver concentrates are high in lead which typically accounts for approximately 90% to 95% of the mill feed silver values since given that is strongly associated with lead minerals. Overall, silver represents 70% to 80% of the value of the ores in the district.

For more information, see Exhibit 96.4, the Technical Report Summary on the Keno Hill Operations, Yukon, Canada, prepared for the Company by Mining Plus Canada Ltd., with an effective date of December 31, 2023.

At December 31, 2024, there were 252 employees at Keno Hill.

As of December 31, 2024, we have recorded a $3.5 million asset retirement obligation for reclamation and closure costs. The net book value of the Keno Hill property and its associated plant, equipment and mineral interests was approximately $373.9 million as of December 31, 2024. The active infrastructure in place at Keno Hill ranges from the 1980s to 2024.

The current mine plan at Keno Hill utilizes estimates of reserves and resources for approximately 13 years of production, through 2037.

C asa Berardi

We have wholly owned and operated Casa Berardi since June 2013. Casa Berardi is located 95 kilometers (59 miles) north of La Sarre in the Abitibi Region of northwestern Quebec, Canada at 49°34'0.72”N Latitude, 79°15'56.05”W Longitude (WGS84). The property borders Ontario to the west and covers parts of Casa Berardi, Dieppe, Raymond, D'Estrees, and Puiseaux townships. We report Casa Berardi as a separate segment in our consolidated financial statements. See Note 4 of Notes to Consolidated Financial Statements and Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations - Casa Berardi for information on its financial performance.

The Casa Berardi Property is in the northern part of the Abitibi Sub province, a subdivision of the Superior Province, the Archean core of the Canadian Shield. The regional geology is characterized by a mixed assemblage of mafic volcanic rocks, flysch-type sedimentary rocks, iron formation, and graphitic mudstone that are limited by a large granodioritic to granitic batholith. Structurally, the property is enclosed in the Casa Berardi Tectonic Zone, a 15 km wide corridor that can be traced over 200 km. Mineralized zones are closely associated with the Casa Berardi Fault and are found on both sides of the fault and are currently restricted to a 500 m wide corridor. Gold mineralization is primarily located in quartz veining in the form of veins of 1 m to multi-meter widths, small-scale veins, or veinlet networks/stockworks. Veins contain only minor sulfides (1% to 3%); sulfides include arsenopyrite, pyrite, and traces of sphalerite, chalcopyrite, pyrrhotite, tetrahedrite, galena, and gold. Arsenopyrite is the main gold-bearing sulfide present in all veins of the deposit

The mine and mill complex are permitted to process 1,600,000 dry metric tonnes (approximately 1,764,000 tons) of ore per year (4,900 tons per day). The mining operations consist of underground and open pit mines. The surface infrastructures include a cyanidation processing mill (carbon-in-leach), tailings impoundment areas, and other support facilities and infrastructure. The map below illustrates the location and access to Casa Berardi:

---

Current reserves at the Casa Berardi mine comprise eight zones at the West Mine, spread over a moderate horizontal distance from each other and located at different mine elevations.

The ore at Casa Berardi is extracted using a combination of underground and open pit mining methods. The mill utilizes a combination of gravity recovery for coarse gold and cyanidation for fine gold. The ore is crushed and ground to produce a slurry suitable for the subsequent recovery processes. Crushing and grinding is accomplished by a jaw crusher followed by a SAG mill and ball mill. Coarse gold reports to the gravity circuit consisting of Knelson concentrators followed by high intensity leaching and electrowinning. Fine gold reports to the cyanide leach train. Due to the presence of naturally occurring organic carbon in the ore, the Carbon-In-Leach (“CIL”) approach is used in a cyanidation circuit. Gold is adsorbed onto carbon in the leach train and later desorbed for electrowinning. Sludge from the electrowinning cells is melted in a furnace to produce doré, the final product produced at Casa Berardi. In 2024, the mill processed 1,523,420 tons, for an average of 4,174 tons per day.

For more information, see Exhibit 96.3, the Technical Report Summary on the Casa Berardi Mine, Northwestern Québec, Canada, prepared for the Company by the QP, RESPEC, with an effective date of December 31, 2023.

The employees at Casa Berardi are employees of Hecla Quebec Inc., our wholly-owned subsidiary, and are not represented by a bargaining agent. There were 483 employees at Casa Berardi at December 31, 2024. We also utilize third-party contractors, which use their employees and equipment, for some of the mining activities at Casa Berardi.

The current mine plan at Casa Berardi utilizes estimates of reserves and resources for approximately 12 years of active production by underground and open pit methods of mining.

The net book value of the Casa Berardi property and its associated plant, equipment and mineral interests was approximately $629.0 million as of December 31, 2024. As of December 31, 2024, we have recorded a $17.0 million asset retirement obligation for reclamation and closure costs at Casa Berardi. We maintain a surety bond as financial guarantee for future reclamation and closure work.

Exploration and development drilling programs are performed using Industry Standard quality control methods for drilling, sampling, and analytical procedures. Standard operating procedure manuals for geology logging, sampling, and assaying are kept at the operations and updated as required. A secure sample chain-of-custody is established to promote the security of samples during transport from the projects to the analytical facilities. All primary analytical laboratories are ISO 9001 certified and sample preparation and analytical procedures are Industry Standard methods for the metals of interest.

Sample batches sent for analysis are controlled by a system of reference samples of known grade inserted into the sample stream and other control samples. Coarse and fine ‘blank,’ sterile, sample materials are used to monitor contamination at the sample preparation and analytical stages; Standard Reference Materials (“SRM”) of known grades are used to measure accuracy of the analytical results; and pulp duplicate samples and coarse reject duplicate samples are used to monitor precision of the analytical results. Blanks and SRM are inserted according to the analytical batch size and overall number of samples but normally result in a 1:10 to 1:20 insertion rate. Duplicate samples are inserted or requested using a similar 1:10 to 1:20 inclusion rate. As a final measure of assay quality, 5% to 10% of the original samples are sent to a second analytical laboratory for check analysis. Periodically, the Company retains experts to perform audits of the commercial laboratories used in the United States, Mexico and Canada.

The main operating properties store data in SQL-based relational database utilities with built-in logic checks that are implemented as new data is imported. Accurate data entry into the database is confirmed by verification upon data entry/import and again before use in final geology interpretation and resource modeling with checks of new data collected during yearly drilling programs.

Geology and mineral control interpretations, grade estimation parameters, grade and density models, reserve estimation parameters, and modifying factors are peer reviewed within the company. Resource grade models are validated using Industry Standard methods and appropriate documentation and reporting are completed to summarize methods and results. All resource and reserve tabulations at the operations are approved by the local management, with their own sets of controls, and then are compiled by the corporate office which also performs its own set of checks on the final numbers.

All personnel responsible for the management of mineral resource and mineral reserve modeling and approval and reporting of mineral resource and mineral reserve statements are QPs with relevant experience in the type of mineralization and deposit under consideration and in the specific type of activity undertaken for the company. All are eligible members or licensees in good standing of a recognized professional organization based on their academic qualifications and experience and comply with professional standards of competence and ethics. We encourage continuing professional development and training for current QPs as well as others in the Company to develop other QPs within the various departments.

As projects advance toward development and production, data density and the geological understanding of the mineral deposit increases. The Company’s internal controls limit some risk in the resource estimation process, but there is inherent risk in resource modeling due to mineral deposit heterogeneity, sample size and distribution, mining style and mining factor assumptions, and mineral processing issues. Independent audits of reserve models from an outside specialist are arranged on a periodic basis for an operating property. The senior technical staff can also determine when changes in mineral resource and reserve models or negative mine reconciliations are material and recommend internal or external auditing of the models and modifying factors.

The following Management’s Discussion and Analysis (“MD&A”) provides information that management believes is relevant to an assessment and understanding of the consolidated financial condition and results of operations of Hecla Mining Company and its subsidiaries (collectively the “Company,” “our,” or “we”). We use certain non-GAAP financial performance measures in our MD&A. For a detailed description of these measures, please see “Non-GAAP Financial Performance Measures” at the end of this item. This item should be read in conjunction with our Consolidated Financial Statements and the notes thereto included in this annual report.

Over view

Hecla Mining Company stands as North America's leading silver producer, with a rich heritage dating back to 1891. Our operations at Greens Creek and Lucky Friday, produced 45% of 2023 U.S. silver production, complemented by significant gold production from Casa Berardi and Greens Creek. We began ramp-up of the Keno Hill mill during the second quarter of 2023. Our strategic positioning in the stable jurisdictions of U.S. and Canada provides us with distinct operational advantages and reduced political risk compared to our global peers. Our operational and strategic framework centers on three core pillars:

2024 Highlights

Operational Achievements:

Financial Performance:

Our average realized prices for silver, gold and zinc increased in 2024 compared to 2023 while lead decreased. Our average realized silver, gold and lead increased while zinc decreased in 2023 compared to 2022. See the Consolidated Results of Operations section below for information on our average realized metals prices for 2024, 2023 and 2022. Lead and zinc represent important by-products at our Greens Creek and Lucky Friday segments, and gold is also a significant by-product at Greens Creek. Copper is a minor by-product credit at Greens Creek, in addition to lead and zinc at Keno Hill.

Key Issues Impacting our Business

Our current business strategy is to focus our financial and human resources in the following areas:

We strive to achieve excellent mine safety and health performance. We seek to implement this goal by: training employees in safe work practices; establishing, following and improving safety standards; investigating accidents, incidents and losses to avoid recurrence; involving employees in the establishment of safety standards; and participating in the National Mining Association’s CORESafety program. We seek to implement reasonable best practices with respect to mine safety and emergency preparedness. We respond to issues outlined in investigations and inspections by MSHA, the Commission of Labor Standards, Pay Equity and Occupational Health and Safety in Quebec, the Workers' Safety and Compensation Board in the Yukon and the Mexico Ministry of Economy and Mining and continue to evaluate our safety practices. There can be no assurance that our practices will mitigate or eliminate all safety risks. Achieving and maintaining compliance with regulations will be challenging and may increase our operating costs. See Item 1A. Risk Factors - We face substantial governmental regulation, including the Mine Safety and Health Act, various environmental laws and regulations and the 1872 Mining Law.

A number of key factors may impact the execution of our strategy, including regulatory issues, metals prices and inflationary pressures on input costs. Metals prices can be very volatile and are influenced by a number of factors beyond our control (except on a limited basis through the use of derivative contracts). See Item 7. Critical Accounting Estimates and Note 10 of Notes to Consolidated Financial Statements . While we believe longer-term global economic and industrial trends could result in continued demand for the metals we produce, prices have been volatile and there can be no assurance that current prices will continue.

Volatility in global financial markets and other factors can pose a significant challenge to our ability to access credit and equity markets, should we need to do so. We utilize forward contracts to manage exposure to declines in the prices of (i) silver, gold, zinc and lead contained in our concentrates that have been shipped but have not yet settled, and (ii) from time to time zinc and lead that we forecast for future concentrate shipments. In addition, we have in place a $225.0 million revolving credit agreement. As of December 31, 2024, $29.2 million of the facility was utilized, with $6.2 million being used for letters of credit, $23.0 million was drawn on the facility, leaving approximately $195.8 million available for borrowing.

Another challenge for us is the risk associated with environmental litigation and ongoing reclamation activities. As described in Item 1A. Risk Factors and in Note 16 of Notes to Consolidated Financial Statements, it is possible that our estimate of these liabilities may change in the future, affecting our strategic plans. We are involved in various environmental legal matters and the estimate of our environmental liabilities and liquidity needs, as well as our strategic plans, may be significantly impacted as a result of these matters or new matters that may arise. We strive to ensure that our activities are conducted in compliance with applicable laws and regulations and attempt to resolve environmental litigation on terms as favorable to us as possible.

Reserve and resource estimation is a major risk inherent in mining. Our reserve and resource estimates, which underlie (i) our mining and investment plans, (ii) the valuation of a significant portion of our long-term assets and (iii) depreciation, depletion and

---

amortization expense, may change based on economic factors and actual production experience. Until ore is mined and processed, the volumes and grades of our reserves and resources must be considered as estimates. Our reserves are depleted as we mine. Reserves and resources can also change as a result of changes in economic and operating assumptions. See Item 1A. Risk Factors - Our mineral reserve and resource estimates may be imprecise.

Consolidated Results of Operations

Total metal sales for the years ended December 31, 2024, 2023 and 2022, and the approximate variances attributed to differences in metals prices, sales volumes and smelter terms, were as follows:

(in thousands)		Silver				Gold				Base metals				Less: smelter and refining charges				Total sales of products
2022		$	265,054			$	298,910			$	206,441			$	(51,973	)		$	718,432

2024		$	413,980			$	318,256			$	218,406			$	(41,273	)		$	909,369

Average market and realized metals prices for 2024, 2023 and 2022 were as follows:

				Average price for the year ended December 31,
				2024				2023				2022
Silver		Realized price per ounce		$	28.58			$	23.33			$	21.53
		London PM Fix ($/ounce)			28.24				23.39				21.75
Gold		Realized price per ounce			2,403				1,939				1,803
		London PM Fix ($/ounce)			2,387				1,943				1,801
Lead		Realized price per pound			0.97				1.03				1.01
		LME Final Cash Buyer ($/pound)			0.94				0.97				0.98
Zinc		Realized price per pound			1.37				1.35				1.41
		LME Final Cash Buyer ($/pound)		$	1.26			$	1.20			$	1.58
Copper		Realized price per pound			4.20				—				—
		LME Final Cash Buyer ($/pound)		$	4.15			NA				NA

Average realized prices differ from average market prices primarily because concentrate sales are generally recorded as revenues at the time of shipment at forward prices for the estimated month of settlement, which differ from average market prices. Due to the time elapsed between shipment of concentrates and final settlement with customers, we must estimate the prices at which sales of our metals will be settled. Previously recorded sales are adjusted to estimated settlement metals prices each period through final settlement. For 2024 and 2023, we recorded net positive price adjustments to provisional settlements of $22.9 million and $18.2 million, respectively, and $20.8 million in net negative price adjustments to provisional settlements in 2022. The price adjustments related to silver, gold, zinc and lead contained in our concentrate sales were partially offset by gains and losses on forward contracts for those metals for each year (see Note 10 of Notes to Consolidated Financial Statements for more information). The gains and losses on these contracts are included in revenues and impact the realized prices for silver, gold, lead and zinc. Realized prices are calculated by dividing gross revenues for each metal (which include the price adjustments and gains and losses on the forward contracts discussed above) by the payable quantities of each metal included in products sold during the period.

Total metals production and sales volumes for each period are shown in the following table:

				Year Ended December 31,
				2024				2023				2022
Silver -		Ounces produced			16,169,930				14,342,863				14,182,987
		Payable ounces sold			14,485,158				12,955,006				12,311,595
Gold -		Ounces produced			141,923				151,259				175,807
		Payable ounces sold			132,442				141,602				165,818
Lead -		Tons produced			52,515				40,347				48,713
		Payable tons sold			44,795				35,429				41,423
Zinc -		Tons produced			66,308				60,579				64,748

Copper -		Tons produced			1,874				1,823				1,904
		Payable tons sold			50				—				—

The difference between what we report as “ounces/tons produced” and “payable ounces/tons sold” is attributable to the difference between the quantities of metals contained in our products versus the portion of those metals actually paid for by our customers pursuant to of our sales contract terms. Differences can also arise from inventory changes incidental to shipping schedules, or variances in ore grades which impact the amount of metals contained in concentrates produced and sold.

While revenue from zinc, lead and gold by-products is significant, we believe that identification of silver as the primary product of Greens Creek, Lucky Friday, and Keno Hill is appropriate because:

Accordingly, we believe the identification of gold, lead, zinc and copper as by-product credits at Greens Creek, Lucky Friday and Keno Hill is appropriate because of their lower economic value compared to silver and due to the fact that silver is the primary product we intend to produce at those locations. In addition, we have not consistently received sufficient revenue from any single by-product metal to warrant classification of such as a co-product.

We periodically review our revenues to ensure that reporting of primary products and by-products is appropriate. Because for Greens Creek, Lucky Friday and Keno Hill we consider zinc, lead, gold and copper to be by-products of our silver production, the values of these metals from Greens Creek and Keno Hill only offset operating costs within our calculations of Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce. We currently do not report Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for our Keno Hill operation as it is in the production ramp-up phase and has not met our definition of commercial production. We define an operation as being in commercial production upon achievement of the following criteria:

Determination of when these criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies.

As Keno Hill has not yet been determined to be in commercial production, it's costs and by-product credits are excluded from our consolidated Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce because (i) by definition it has not reached the sustaining stage and (ii) including its costs and by-product credits we believe would distort consolidated Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce of our operating silver mines that are in commercial production and operating as designed, and not facilitate a meaningful comparison of our performance versus that of our peers.

We believe the identification of silver as a by-product credit is appropriate at Casa Berardi because of its lower economic value compared to gold and due to the fact that gold is the primary product we intend to produce. In addition, we do not receive sufficient revenue from silver at the Casa Berardi to warrant classification of such as a co-product. Because we consider silver to be a by-product of our gold production at Casa Berardi, the value of silver offsets operating costs within our calculations of Cash Cost, After By-product Credits, per Gold Ounce and AISC, After By-product Credits, per Gold Ounce.

Gross profit increased by $28.8 million to $153.4 million in 2024 from $124.6 million in 2023, due to higher realized prices for all metals sold other than lead, partly offset by lower sales volumes for all metals, except zinc, and higher production costs which primarily consist of higher labor and contractor costs and higher equipment maintenance. See Item 1A. Risk Factors - Our profitability could be affected by inflation, including the prices of other commodities for a discussion of certain risks related to our operations profitability.

Gross profit increased by $22.3 million to $124.6 million in 2023 from $102.3 million in 2022, as higher realized prices for all metals sold other than zinc and higher payable metal quantities for all metals sold compared to 2022, was offset by higher production costs reflecting more tons milled, and related higher labor, maintenance and consumables costs. See Item 1A. Risk Factors - Our profitability could be affected by inflation, including the prices of other commodities for a discussion of certain risks related to our operations profitability.

Capital additions increased by $4.3 million in 2024 to $47.8 million compared to 2023. Significant components of the 2024 capital additions were $15.1 million on mobile equipment, a $5.3 million increase over 2023, $16.9 million on mine and primary ore access development, $6.5 million of definition drilling, and $3.8 million towards a concentrator .

During August 2023, the production at the mine was suspended due to a fire that occurred while repairing an unused station in the #2 ventilation shaft, which is also the secondary egress (required by MSHA regulations). By early September, the fire had been extinguished, normal ventilation was reestablished and the workforce recalled. Following evaluation of alternatives, it was determined that in order to safely bring the mine back into production in the most rapid and cost effective way, a new secondary egress needed to be developed to bypass the damaged portion of the #2 shaft. The new egress involved extending an existing ramp 1,600 feet, installing a 290-foot-long manway raise, and developing an 850 foot ventilation raise. This work resulted in operations being suspended for the remainder of 2023, with the mine restarting production on January 9, 2024, and ramping up to full production during the first quarter. The Company has property and business interruption insurance coverage with an underground sub-limit of $50.0 million, and received the full coverage amount of $50.0 million in 2024. The discussion of Lucky Friday's results below for the years ended December 31, 2024 and 2023 has been impacted by this prior suspension of operations.

Gross profit in 2024 of $58.7 million, was $26.6 million higher than 2023, primarily due to higher realized prices for silver, and higher sales volumes for all metals produced due to the suspension of mining operations mentioned above. For the year ended December 31, 2024, $2.2 million of site specific suspension costs were included within Ramp-up and suspension costs on our consolidated statements of operations and comprehensive income (loss), compared to $25.5 million in 2023.

---

Gross profit in 2023 of $32.1 million, was $0.9 million higher than 2022, due to higher grades, higher realized silver and lead prices and higher tons milled per day prior to the shutdown in August 2023 compared to 2022. As mentioned above, in 2023, $25.5 million of site specific suspension costs were included within Ramp-up and suspension costs.

Total capital additions decreased by $15.7 million in 2024 to $49.6 million compared to 2023 as the prior year contained investments made to support sustained higher throughput and costs incurred to build the secondary egress following the August 2023 fire. Capital expenditures decreased as the prior year included expenditures for the installation of a service hoist, coarse ore bunker and shaft and related infrastructure.

We have not disclosed cost per ounce statistics for the Keno Hill operation as it is in the production ramp-up phase and has not met our definition of commercial production. See above "Consolidated Results of Operations" for our definition of commercial production. Determination of when those criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies.

We acquired our Keno Hill operations as part of the Alexco acquisition in September 2022 and have focused on development activities and began ramp-up of the mill during the second quarter of 2023. The average throughput during the year ended December 31, 2024, was 299 tons per day (the mine is currently permitted to a maximum of an average of 440 tons per day), with silver grades milled of 26.2 ounces per ton. Mill throughput was negatively impacted by events beginning in late August, 2024, and continuing into 2025 as described below.

From commencement of production until late August, 2024, ore production and mill throughput generally increased as planned, leading to increased levels of production (though still not reaching profitability or the permitted capacity at the mill). However, production was paused between August 27 and October 26 as a consequence of the heap leach failure at Victoria Gold’s Eagle Mine in late June 2024. This failure had several immediate and ongoing impacts on our operations. The primary impact was we were forced to suspend milling operations at Keno Hill on August 27 due to delays in receiving an authorization for mill construction and a permit modification Keno Hill’s dry stack tailings storage facility (“DSTF”). The delayed authorization and permit were a result of the focus of the Yukon Government (“YG”) and the First Nation of Na-Cho Nyäk Dun (“FNNND”) on Eagle Mine incident response and not on routine permitting matters. Mill operations resumed on October 26, 2024 after receiving the authorization and modification and completing related design and construction work on the DSTF. A second impact of the Eagle Mine incident was the expression of strong positions by the FNNND on continuing and future mining activities at projects within their Traditional Territory, where Keno Hill (and Eagle Mine) is located, including a call to halt mining production. We are committed to responsible and sustainable mining that governments and local communities support, including the FNNND. As such, we project that the matters described in this paragraph will impact production at Keno in 2025 as discussed below.

In late October 2024, Yukon Energy experienced a turbine failure at its hydroelectric plant in Whitehorse that it does not expect to repair until summer 2025. In published reports, the failed turbine is responsible for meeting as much as 40% of the winter demand for power in the Yukon Territory. That failure, combined with cold temperatures in the Yukon (and the resulting increase in demand for power), has caused Yukon Energy to throttle power to Keno Hill, which does not have sufficient backup generation capacity to fully

power the mine and the mill. As a result, on several occasions in late 2024, Keno Hill had insufficient power to run the mine and the mill. We estimate that this caused us in the fourth quarter to incur (i) a loss of approximately 130,000 ounces of silver production and (ii) labor costs for idled employees of approximately $500,000.

Power curtailment at Keno Hill has persisted into 2025, resulting in at least 8 days of operational stoppage as of the date of this report. We anticipate these disruptions will continue through the first quarter of 2025 due to cold temperatures and regional power supply constraints. Considering these power challenges, along with ongoing discussions with the YG and the FNNND regarding the Eagle Mine incident, we project 2025 silver production to remain comparable to 2024 levels, with growth expected to resume in 2026. In 2025, the Company's environmental remediation services group is also expected to increase construction activities, adding incremental demand on Keno Hill's infrastructure and resources. The projected flat production levels at Keno Hill for 2025 should allow us to focus on stakeholder outreach and ensuring we have local support for increasing production levels by 2026, as well as permitting, infrastructure and capital projects.

As stated above, Keno Hill has not been profitable for us at current throughput rates and prices. We estimate that to become profitable at current metals prices, throughput rates would need to reach approximately 500 to 600 tons per day, which would require permit modifications or new permits and significant capital expenditures. See Item 1A. Risk Factors - We may not realize all of the anticipated benefits from our acquisitions, including our 2022 acquisition of Alexco .

During the year ended December 31, 2024, Keno Hill recorded sales and total cost of sales of $75.0 million, related to the concentrate produced and sold during the ramp up. During the year ended December 31, 2024, $26.8 million of site specific ramp up costs were included within Ramp-up and suspension costs and $7.8 million of site specific exploration costs were included within Exploration and pre-development as reported on our consolidated statements of operations and comprehensive income (loss). During the year ended December 31, 2024, Keno Hill recorded capital additions of $54.9 million, of which $28.1 million related to mine development, $8.8 million related to the DSTF, $5.9 million related to mine mobile equipment, $3.2 million for camp upgrades and $2.9 million for the surface backfill plant.

During the year ended December 31, 2023, Keno Hill recorded sales and total cost of sales of $35.5 million, related to the concentrate produced and sold during the ramp up. During the year ended December 31, 2023, $29.8 million of site specific ramp up costs were included within Ramp-up and suspension costs and $4.7 million of site specific exploration costs were included within Exploration and pre-development as reported on our consolidated statements of operations and comprehensive (loss) income. During the year ended December 31, 2023, Keno Hill recorded capital additions of $44.7 million, of which $29.6 million related to mine development and $11.3 million to mobile equipment purchases, crusher modifications and camp upgrades.

As part of the transition of the Casa Berardi mine from a combined underground and open pit operation to an open pit only operation, mining is ongoing at the 160 open pit, but the lower margin east mine underground operations were closed in July 2023 and, the only underground mining since July 2023 has been at the higher margin stopes of the west underground mine, which will be mined until they are exhausted (expected to occur in mid-2025), at which time most underground activity is expected to cease. Following the halt to underground mining, Casa Berardi is expected to only produce gold from the 160 open pit, and at lower volumes than historic production levels, with production expected to conclude at the 160 open pit in 2027. We forecast a gap in production commencing in 2027 and lasting until 2032 or later, when no ore is expected to be mined and no revenue is expected. During this hiatus, our focus is expected to be on investing in infrastructure and equipment, permitting and de-watering and stripping two expected new open pits, Principal and West Mine Crown Pillar. If we are able to successfully permit, design and construct the new open pits, then upon conclusion of the hiatus, the mine is expected to generate significant free cash flow at current gold prices.

Gross loss decreased by $29.7 million to $13.9 million in 2024 compared to $43.7 million in 2023. The decrease in gross loss primarily relates to an increase in realized gold prices, partly offset by lower gold sales volumes. For 2024, the benefit of lower production costs due to the closure of the east mine in July 2023, was largely offset by increased depreciation expense from the accelerated amortization of the west underground mine in the first half of 2024. See Item 1A. Risk Factors - Our profitability could be affected by inflation, including the prices of other commodities for a discussion of certain risks related to our operation's profitability.

Gross loss increased by $29.9 million to $43.7 million in 2023 compared to $13.8 million in 2022 as higher average realized gold prices did not offset the impact of lower gold production. This increase in gross loss includes $12.7 million in product inventory net realizable value write downs due to a combination of higher direct production costs and higher depreciation, depletion and amortization expense effective July 2023, reflecting the accelerated amortization of the west underground mine. The increase in gross loss was also due to the processing of lower grade ore tonnage from both the underground and surface operations, higher costs related to mill maintenance and optimization activities, higher underground maintenance costs resulting from repairs and replacements of major components for the production fleet, and higher fuel and other consumables costs, compared to 2022. Suspension costs amounted to $2.2 million for 2023, as Casa Berardi's operations were suspended for 20 days in June, due to wildfires in Quebec which resulted in the

Quebec Ministry of Natural Resources and Forests closing certain forest lands and access roads. No production or sales took place during the suspension period. See Item 1A. Risk Factors - Our profitability could be affected by inflation, including the prices of other commodities for a discussion of certain risks related to our operation's profitability.

Although Casa Berardi generated gross profits during the third and fourth quarter of 2024, it has generated gross losses for the last three years (including 2024) and for eight of the last ten quarters. This lack of profitability, the expected hiatus in future production discussed above, the uncertainty surrounding permitting and pit design and construction, and the time involved to resolve these uncertainties, has caused us to undertake a review of how Casa Berardi fits into the Company's future strategy. While it is possible we may continue down the path towards future production at the Principal and West Mine Crown Pillar pits, we are also examining potential strategic alternatives.

Total capital additions decreased by $9.4 million in 2024 compared to 2023 as the prior year contained a significant amount of purchases of new surface fleet equipment as the mine transitioned from an underground to an open pit operation. The majority of 2024 capital expenditures consisted of tailings dam construction costs. Total capital additions increased by $30.4 million in 2023 compared to 2022 primarily due to purchases of new surface fleet equipment, as mentioned above, and the construction of tailings storage facilities. Significant components of 2023 capital expenditures were tailings dam construction costs of $41.0 million, $18.2 million on machinery and equipment, and $11.2 million on development.

The chart below illustrates the factors contributing to Cash Cost, After By-product Credits, Per Gold Ounce for 2024, 2023 and 2022:

By-product credits per gold ounce			(8	)			(6	)			(5	)
AISC, After By-product Credits, per Gold Ounce		$	1,990			$	2,048			$	1,773

The increase in Cash Cost, After By-product Credits, per Gold Ounce for 2024 compared to 2023 and 2022 was primarily driven by lower gold production, partly offset by lower production costs due to the cessation of underground mining of the east mine in July 2023. The decrease in AISC, After By-product Credits, per Gold Ounce for 2024 compared to 2023 is primarily due to sustaining capital expenditures that were $16.0 million lower, primarily resulting from lower deferred development costs.

Corporate Matters

Employee Benefit Plans

Our defined benefit pension plans, while providing a significant benefit to our employees, have historically represented a significant liability to us. During 2024, the funded status of our plans assets decreased to $16.3 million at December 31, 2024 from $27.5 million at December 31, 2023. We do not expect to be required to contribute to our defined benefit plans in 2025, but we may choose to do so. See Note 6 of Notes to Consolidated Financial Statements for more information. We periodically examine the defined benefit pension plans and supplemental excess retirement plan for affordability and competitiveness.

Income and Mining Taxes

Our deferred tax assets and liabilities are measured at the currently enacted tax rates that are expected to apply in years in which they are expected to be paid for or realized. Each reporting period we assess the realizability of our tax assets. In assessing the need for a valuation allowance, we evaluate all significant available positive and negative evidence, including historical operating results, estimates of future sources of taxable income, carry-forward periods available, the existence of prudent and feasible tax planning strategies and other relevant factors.

Our organizational structure requires us to have two U.S. tax groups that do not consolidate. Hecla Mining Company and subsidiaries (“Hecla U.S. Group”) has a net deferred tax liability of $21.7 million at December 31, 2024 compared to a net deferred tax asset of $2.9 million at December 31, 2023. The decrease of $24.6 million is primarily related to utilization of tax loss carryforwards.

Klondex Mines Ltd (“Klondex”) is a separate U.S. tax group (“Nevada U.S. Group”) that has a net deferred tax liability of $30.8 million and $30.8 million at December 31, 2024 and 2023, respectively.

Our net Canadian deferred tax liability at December 31, 2024 was $57.8 million, a decrease of $16.3 million from the $74.1 million net deferred tax liability at December 31, 2023. The decrease was due to current period activity.

Our Mexican net deferred tax asset at December 31, 2024 remains at zero with no change from December 31, 2023. The valuation allowance decreased to $11.6 million due to utilization and expiration of deferred tax assets at our operations in Mexico.

As a result of the Tax Cuts and Jobs Act (“TCJA”) enacted in December 2017, under Internal Revenue Code Section 174, a requirement to capitalize and amortize research and experimental expenditures for tax years beginning after December 31, 2021 is now effective. This modification has not had a material impact.

As discussed in Note 7 of Notes to Consolidated Financial Statements , our effective tax rate for 2024 was 46%, reflecting a tax expense of $30.4 million on pre-tax income of $66.2 million, compared to a negative 1% for 2023, reflecting a tax expense of $1.2 million on a pre-tax loss of $83.0 million. We are subject to income taxes in the United States and other foreign jurisdictions. The overall effective tax rate will continue to be dependent upon the geographic distribution of our earnings in different jurisdictions, the U.S. deduction for percentage depletion, fluctuation in foreign currency exchange rates and deferred tax asset valuation allowance changes. As a result, the 2025 effective tax rate could vary significantly from that of 2024. The other relevant provisions of the TCJA that became effective in 2018 consist of global intangible low-taxed income tax and base erosion and anti-abuse tax; however, these provisions have not had a material impact.

Reconciliation of Total Cost of Sales to Cash Cost, Before By-product Credits and Cash Cost, After By-product Credits (non-GAAP) and All-In Sustaining Cost, Before By-product Credits and All-In Sustaining Cost, After By-product Credits (non-GAAP)

The tables below present reconciliations between the most comparable GAAP measure of total cost of sales to the non-GAAP measures of (i) Cash Cost, Before By-product Credits, (ii) Cash Cost, After By-product Credits, (iii) AISC, Before By-product Credits and (iv) AISC, After By-product Credits for our operations and for the Company for the years ended December 31, 2024, 2023 and 2022.

Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce are measures developed by precious metals companies (including the Silver Institute and the World Gold Council) in an effort to provide a uniform standard for comparison purposes. There can be no assurance, however, that these non-GAAP measures as we report them are the same as those reported by other mining companies.

Cash Cost, After By-product Credits, per Ounce is an important operating statistic that we utilize to measure each mine's operating performance. We use AISC, After By-product Credits, per Ounce as a measure of our mines' net cash flow after costs for reclamation and sustaining capital. This is similar to the Cash Cost, After By-product Credits, per Ounce non-GAAP measure we report, but also includes reclamation and sustaining capital costs. Current GAAP measures used in the mining industry, such as cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce also allow us to benchmark the performance of each of our mines versus those of our competitors. As a silver and gold mining company, we also use these statistics on an aggregate basis - aggregating the Greens Creek and Lucky Friday mines to compare our performance with that of other silver mining companies. Similarly, these statistics are useful in identifying acquisition and investment opportunities as they provide a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics.

We have not disclosed cost per ounce statistics for the Keno Hill operation as it is in the production ramp-up phase and has not met our definition of commercial production. See above "Consolidated Results of Operations" for our definition of commercial production. Determination of when those criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies.

Cash Cost, Before By-product Credits and AISC, Before By-product Credits include all direct and indirect operating cash costs related directly to the physical activities of producing metals, including mining, processing and other plant costs, third-party refining expense, on-site general and administrative costs, royalties and mining production taxes. AISC, Before By-product Credits for each mine also includes reclamation and sustaining capital costs. AISC, Before By-product Credits for our consolidated silver properties also includes corporate costs for general and administrative expense and sustaining capital costs. By-product credits include revenues earned from all metals other than the primary metal produced at each unit. As depicted in the tables below, by-product credits comprise an essential element of our silver unit cost structure, distinguishing our silver operations due to the polymetallic nature of their orebodies.

In addition to the uses described above, Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce provide management and investors an indication of operating cash flow, after consideration of the average price received from production. We also use these measurements for the comparative monitoring of performance of our mining operations period-to-period from a cash flow perspective.

Casa Berardi reports Cash Cost, After By-product Credits, per Gold Ounce and AISC, After By-product Credits, per Gold Ounce for the production of gold, their primary product, and by-product revenues earned from silver, which is a by-product at Casa Berardi. Only costs and ounces produced relating to units with the same primary product are combined to represent Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce. Thus, the gold produced at Casa Berardi is not included as a by-product credit when calculating Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver

---

Ounce for the total of Greens Creek and Lucky Friday, our combined silver properties. Similarly, the silver produced at our other three units is not included as a by-product credit when calculating the gold metrics for Casa Berardi

Financial Liquidity and Capital Resources

Liquidity overview

We have a disciplined cash management strategy of maintaining financial flexibility to execute our capital priorities and provide long-term value to our stockholders. Consistent with that strategy, we aim to maintain an acceptable level of net debt and sufficient liquidity to fund debt service costs, operations, capital expenditures, exploration and pre-development projects, while returning cash to stockholders through dividends and potential share repurchases.

At December 31, 2024, we had $26.9 million in cash and cash equivalents, of which $2.4 million was held in foreign subsidiaries' local currency that we anticipate utilizing for near-term operating, exploration or capital costs by those foreign subsidiaries. At December 31, 2024, we had utilized $29.2 million drawn on our credit facility with $6.2 million for letters of credit, and the remaining $23.0 million as borrowings. We also have USD cash and cash equivalent balances held by our foreign subsidiaries that, if repatriated, may be subject to withholding taxes. We expect that there would be no additional tax burden upon repatriation after considering the cash cost associated with the withholding taxes. We believe that our liquidity and capital resources from our U.S. operations are adequate to fund our U.S. operations and corporate activities.

Pursuant to our common stock dividend policy described in Note 12 of Notes to Consolidated Financial Statements , our Board of Directors declared and paid dividends on common stock totaling $24.9 million in 2024, $15.2 million in 2023 and $12.4 million in 2022. Until February 2025, our dividend policy had a silver-linked component which tied the amount of declared common stock dividends to our realized silver price for the preceding quarter (our dividend policy was recently revised, see discussion below). Another component of our common stock dividend policy, which remains in place, anticipates paying an annual minimum dividend. We realized silver prices of $24.77, $29.77, $29.43 and $30.19 in the first, second, third and fourth quarters of 2024, respectively, thus satisfying the criterion for the silver-linked dividend component of our common stock dividend policy. As a result, on May 8, 2024, August 6, 2024, November 6, 2024, and February 7, 2025 our Board of Directors declared quarterly cash dividends of $0.00625 per share of common stock, consisting of $0.00375 per share for the minimum dividend component and $0.0025 per share for the now discontinued silver-linked dividend component of our dividend policy, for the first and second quarters of 2024, and quarterly cash dividends of $0.01375 per share of common stock, consisting of $0.00375 per share for the minimum dividend component and $0.010 per share for the silver linked dividend component for the third and fourth quarters of 2024.

In early February 2025, we revised our common stock dividend policy to eliminate the silver-linked component. We intend to maintain the annual common stock dividend, however the declaration and payment of dividends remain in the sole discretion of our Board of Directors, and there can be no assurance it will declare any future dividend.

As discussed in Note 12 of Notes to Consolidated Financial Statements , pursuant to an equity distribution agreement dated February 18, 2021, we may offer and sell up to 60 million shares of our common stock from time to time to or through sales agents in “at-the-market” (ATM) offerings. Sales of the shares, if any, will be made by means of ordinary brokers transactions or as otherwise agreed between the Company and the agents as principals. Whether or not we engage in sales from time to time may depend on a variety of factors, including share price, our cash resources, customary black-out restrictions, and whether we have any material inside information. The agreement can be terminated by us at any time. Any sales of shares under the equity distribution agreement are registered under the Securities Act of 1933, as amended, pursuant to a shelf registration statement on Form S-3. During the year ended December 31, 2024, we sold 9,339,287 shares under the agreement for proceeds of $58.4 million, net of commissions and fees of approximately $0.9 million. As of December 31, 2024, we have sold a total of 23,843,684 shares under the agreement for proceeds of $132.3 million, net of commissions and fees of $2.1 million.

As a result of our current cash balances, the performance of our current and expected operations, current metals prices, proceeds from potential at-the-market sales of common stock, and availability under our Credit Agreement (refer to Note 9 of Notes to Consolidated Financial Statements) , we believe we will be able to meet our obligations and other potential cash requirements during the next 12 months from the date of this report. Our obligations and other uses of cash may include, but are not limited to: debt service obligations related to the Senior Notes and our Series 2020-A Senior Notes due July 9, 2025 (the “IQ Notes”) issued to Investissement Québec, a financing arm of the Québec government, which have total principal of CAD$48.2 million and bear interest at a rate of 6.515%; principal and interest payments under our Credit Agreement; deferral of revenues, ramp-up and suspension costs at certain of our operations; capital expenditures at our operations; potential acquisitions of other mining companies or properties; regulatory matters; litigation; potential repurchases of our common stock under the program described above; and payment of dividends on common stock, if declared by our Board of Directors. We currently estimate a range of approximately $222 to $242 million will be spent in 2025 on capital expenditures, primarily for equipment, infrastructure, and development at our mines, before any lease financing. We also estimate exploration and pre-development expenditures will total approximately $28 million in 2025. Our expenditures for these items and our

---

related plans for 2025 may change based upon our financial position, metals prices, and other considerations. Our ability to fund the activities described above will depend on our operating performance, metals prices, our ability to estimate revenues and costs, sources of liquidity available to us, including the revolving credit facility, and other factors. A sustained downturn in metals prices, significant increase in operational or capital costs or other uses of cash, our inability to access the credit facility or the sources of liquidity discussed above, or other factors beyond our control could impact our plans. See Item 1A. Risk Factors - An extended decline in metals prices, an increase in operating or capital costs, or treatment charges, mine accidents or closures, increasing regulatory obligations, or our inability to convert resources or exploration targets to reserves may cause us to record write-downs, which could negatively impact our results of operations and We have a substantial amount of debt that could impair our financial health and prevent us from fulfilling our obligations under our existing and future indebtedness.

We may defer some capital expenditures and/or exploration and pre-development activities, engage in asset sales or secure additional capital if necessary to maintain liquidity. We also may pursue additional acquisition opportunities, which could require additional equity issuances or other forms of financing. We cannot assure you that such financing will be available to us.

Our liquid assets excluding restricted cash and cash equivalents include (in millions):

		December 31, 2024				December 31, 2023				December 31, 2022
Cash and cash equivalents held in U.S. dollars		$	24.5			$	98.8			$	86.8

Marketable equity securities			33.2				32.3				24.0
Total cash, cash equivalents and investments		$	60.1			$	138.7			$	128.7

Cash and cash equivalents decreased by $79.5 million in 2024, for the reasons discussed below. Cash and cash equivalents held in foreign currencies primarily represents balances in CAD, and decreased by $5.2 million in 2024 due to a decrease in CAD held at our Canadian operations. The value of marketable equity securities at the end of 2024 was consistent with the prior year.

		Year Ended December 31,
		2024				2023				2022
Cash provided by operating activities (in millions)		$	218.3			$	75.5			$	89.9

Cash provided by operating activities increased by $142.8 million in 2024 compared to 2023. The increase was due to higher income, adjusted for non-cash items, which increased by $172.2 million, partly offset by the negative impact of working capital and other operating asset and liability changes. Income, adjusted for non-cash items, was higher due to higher realized prices for all metals, except lead, and higher volumes sold, except for gold. Higher volumes sold resulted from the current year containing a full year of production from Keno Hill and Lucky Friday (which had suspended operations for 5 months of the year due to the 2023 fire). Negative working capital and other operating asset and liability changes contributed to a cash decrease of $29.5 million in 2024 compared to 2023. Significant variances in working capital changes between 2024 and 2023 resulted from negative movements in accounts receivables as Lucky Friday operations were suspended at December 31, 2023.

Cash provided by operating activities decreased by $14.4 million in 2023 compared to 2022. The decrease was due to lower income, adjusted for non-cash items, further compounded by the negative impact of working capital and other operating asset and liability changes. Income, adjusted for non-cash items, was lower by $4.8 million primarily due to increased loss from operations, which was mainly a result of higher ramp-up and suspension costs associated with continued ramp-up at Keno Hill and suspension of operations at Lucky Friday. Working capital and other operating asset and liability changes resulted in a net cash decrease of $9.6 million in 2023 compared to 2022. Significant variances in working capital changes between 2023 and 2022 resulted from lower cash flows from changes in other current and non-current assets and accrued payroll and related benefits.

		2024				2023				2022
Cash used in investing activities (in millions)		$	(212.9	)		$	(231.3	)		$	(187.3	)

Capital expenditures, excluding $5.6 million in net non-cash finance lease additions, were $214.5 million in 2024, which was $9.4 million lower than 2023, primarily due to the prior year containing costs related to Lucky Friday making investments to support sustained higher throughput and building the secondary egress following the August 2023 fire, partly offset by higher capital investments at Keno Hill.

---

Capital expenditures, excluding $16.1 million in non-cash finance lease additions, were $223.9 million in 2023, which was $74.5 million higher than 2022. The major components of this increase were from an increase of $30.4 million at Casa Berardi primarily due to purchases of new surface fleet equipment as the mine transitions from an underground to an open pit operation and the construction of tailings storage facilities, an increase of $24.9 million at Keno Hill related to mine development, mobile equipment purchases, crusher modifications and camp upgrades, and an increase of $14.3 million at Lucky Friday as investments were made to support sustained higher throughput and costs were incurred to build the secondary egress following the August 2023 fire. During 2023, we acquired investments in other mining companies and short term investments for a total of $9.0 million.

During 2024, we drew down a cumulative $279 million and repaid a cumulative $384 million on our Credit Agreement. We drew down a cumulative $239 million and repaid a cumulative $111 million and drew down and repaid $25.0 million on our Credit Agreement during 2023 and 2022, respectively. In 2024, 2023 and 2022, we paid total cash dividends on our common and preferred stock of $25.3 million, $15.7 million and $12.9 million, respectively. We made payments on our finance leases of $10.5 million, $10.6 million, and $7.6 million in 2024, 2023, and 2022, respectively. We issued stock under our ATM program described above for net proceeds of $58.4 million, $56.7 million and $17.3 million in 2024, 2023 and 2022, respectively. During 2024, 2023 and 2022, we also purchased shares of our common stock for $1.2 million, $2.0 million and $3.7 million, respectively, as a result of our employees' election to utilize net share settlement to satisfy their tax withholding obligations related to incentive compensation paid in stock and vesting of restricted stock units. See Note 12 of Notes to Consolidated Financial Statements for more information.

Exchange rate fluctuations between the U.S. dollar and the Canadian dollar and Mexican peso resulted in a decrease in our cash balance of $1.1 million, an increase of $1.1 million, and a decrease of $0.3 million, during 2024, 2023 and 2022, respectively.

Contractual Obligations and Contingent Liabilities and Commitments

The table below presents our fixed, non-cancelable contractual obligations and commitments primarily related to our Senior Notes, IQ Notes, revolving credit facility, outstanding purchase orders and certain service contract commitments, and lease arrangements as of December 31, 2024 (in thousands):

We record liabilities for estimated costs associated with mine closure, reclamation of land and other environmental matters. At December 31, 2024, our liabilities for these matters totaled $124.9 million. Future expenditures related to closure, reclamation and environmental expenditures at our other sites are difficult to estimate, although we anticipate we will incur expenditures relating to these obligations over the next 30 years. For additional information relating to our environmental obligations, see Note 5 of Notes to Consolidated Financial Statements and Item 1A. Risk Factors – Our environmental obligations may exceed the provisions we have made . As discussed in Note 16 of Notes to Consolidated Financial Statements , we are involved in various other legal proceedings which may result in obligations in excess of provisions we have made.

Critical Accounting Estimates

Our significant accounting policies are described in Note 2 of Notes to Consolidated Financial Statements. As described in such Note 2 , we are required to make estimates and assumptions that affect the reported amounts and related disclosures of assets, liabilities, revenue, and expenses. Our estimates are based on our experience and our interpretation of economic, political, regulatory, and other factors that affect our business prospects. Actual results may differ significantly from our estimates.

We believe that our most critical accounting estimates are related to future metals prices; obligations for environmental, reclamation, and closure matters; mineral reserves and resources; valuation of deferred tax assets and assumptions used in accounting for our pension plans, as they require us to make assumptions that are highly uncertain at the time the accounting estimates are made and changes in them are reasonably likely to occur from period to period. Management has discussed the development and selection of these critical accounting estimates with the Audit Committee of our Board of Directors, and the Audit Committee has reviewed the disclosures presented below. In addition, there are other items within our financial statements that require estimation, but are not deemed to be critical. However, changes in estimates used in these and other items could have a material impact on our financial statements.

Future Metals Prices

Metals prices are key components in estimates that determine the valuation of some of our significant assets and liabilities, including properties, plants, equipment and mine development, deferred tax assets, and certain accounts receivable. Metals prices are also an important component in the estimation of reserves and resources. As shown above in Item 1. – Business , metals prices have historically been volatile. Silver demand arises from investment demand, particularly in exchange-traded funds, industrial demand, and consumer demand. Gold demand arises primarily from investment and consumer demand. Investment demand for silver and gold can be influenced by several factors, including: the value of the U.S. dollar and other currencies, changing U.S. budget deficits, widening availability of exchange-traded funds, interest rate levels, the health of credit markets, and inflationary expectations. Uncertainty related to (i) the political environment in the U.S., (ii) U.S. and global trading policies (including tariffs), (iii) a global economic recovery, and (iv) recent uncertainty in China, could result in continued investment demand for precious metals. Industrial demand for silver is closely linked to world Gross Domestic Product growth and industrial fabrication levels, as it is difficult to substitute for silver in industrial fabrication. Consumer demand is driven significantly by demand for jewelry and other retail products. We believe that long-term industrial and economic trends, including demand for metals to decarbonize the economy and urbanization and growth of the middle class in countries such as China and India, will result in continued consumer demand for silver and gold and industrial demand for silver. There can be no assurance whether these trends will continue or how they will impact prices of the metals we produce. In the past, we have recorded impairments to our asset carrying values because of low prices, and we can offer no assurance that prices will either remain at their current levels or increase.

Processes supporting valuation of our assets and liabilities that are most significantly affected by metals prices include analysis of asset carrying values, depreciation, reserves and resources, and deferred income taxes. On at least an annual basis - and more frequently if circumstances warrant - we examine our depreciation rates, reserve estimates, and the valuation allowances on our deferred tax assets. We examine the carrying values of our assets as changes in facts and circumstances warrant. In our evaluation of carrying values and deferred taxes, we apply several pricing views to our forecasting model, including current prices, analyst price estimates, forward-curve prices, and historical prices (see Mineral Reserves and Resources , below, regarding prices used for reserve and resource estimates). Using applicable accounting guidance and our view of metals markets, we use the probability-weighted average of the various

---

methods to determine whether the values of our assets are fairly stated, and to determine the level of valuation allowances, if any, on our deferred tax assets. In addition, estimates of future metals prices are used in the valuation of certain assets in the determination of the purchase price allocations for our acquisitions.

Sales of concentrates sold directly to customers are recorded as revenues upon completion of the performance obligations and transfer of control of the product to the customer (generally at the time of shipment) using estimated forward metals prices for the estimated month of settlement. Due to the time elapsed between shipment of concentrates to the customer and final settlement with the customer, we must estimate the prices at which sales of our metals will be settled. Previously recorded sales and trade accounts receivable are adjusted to estimated settlement prices until final settlement by the customer. Changes in metals prices between shipment and final settlement result in changes to revenues and accounts receivable previously recorded upon shipment. As a result, our trade accounts receivable balances related to concentrate sales are subject to changes in metals prices until final settlement occurs. For more information, see Note 4 of Notes to Consolidated Financial Statements .

We utilize financially-settled forward contracts to manage our exposure to changes in prices for silver, gold, zinc and lead. See Item 7A. – Quantitative and Qualitative Disclosures About Market Risk - Commodity-Price Risk Management below for more information on our contract programs. Changes in silver, gold, zinc and lead prices between the dates that the contracts are entered into and their settlements will result in changes to the fair value asset or liability associated with the contracts, with a corresponding gain or loss for silver and gold contracts recognized in earnings and gain or loss for lead and zinc contracts deferred to accumulated other comprehensive income (loss).

Obligations for Environmental, Reclamation and Closure Matters

Accrued reclamation and closure costs can represent a significant and variable liability on our balance sheet. We have estimated our liabilities under appropriate accounting guidance; however, the ranges of liability could exceed the liabilities recognized. If substantial damages were awarded, claims were settled, or remediation costs incurred in excess of our accruals, our financial results or condition could be materially adversely affected.

Mineral Reserves and Resources

Critical estimates are inherent in the process of determining our reserves and resources. Our reserves and resources are affected largely by our assessment of future metals prices, as well as by engineering and geological estimates of ore grade, accessibility, future recoveries, capital expenditures and production costs. See Item 2. – Properties above for the metals price assumptions used in our estimates of reserves and resources as of December 31, 2024, 2023 and 2022. Our assessment of reserves and resources occurs at least annually. Periodically we utilize external specialists to perform independent audits of our operating properties reserves and resources.

Reserves and resources are a key component in the valuation of our properties, plants and equipment. Reserve estimates are used in determining appropriate rates of units-of-production depreciation, with net book value of many assets depreciated over remaining estimated reserves. Reserves and resources are also a key component in forecasts, with which we compare future cash flows to current asset values in an effort to ensure that carrying values are reported appropriately. Our forecasts are also used in determining the level of valuation allowances on our deferred tax assets. Reserves and resources also play a key role in the valuation of certain assets in the determination of the purchase price allocations for acquisitions. Annual reserve and resource estimates are also used to determine conversions of resources and exploration targets beyond the known reserve resulting from business combinations to depreciable reserves, in periods subsequent to the business combinations. Reserves and resources are a culmination of many estimates and are not guarantees that we will recover the indicated quantities of metals or that we will do so at a profitable level.

Valuation of Deferred Tax Assets

Our deferred income tax assets include certain future tax benefits. We record a valuation allowance against any portion of those deferred income tax assets when we believe, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income tax asset will not be realized. We review the likelihood that we will realize the benefit of our deferred tax assets and therefore the need for valuation allowances on a quarterly basis, or more frequently if events indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results of the legal entity or consolidated group recording the net deferred tax asset is considered, along with all other available positive and negative evidence.

Certain categories of evidence carry more weight in the analysis than others based upon the extent to which the evidence may be objectively verified. We look to the nature and severity of cumulative pretax losses (if any) in the current three-year period ending on the evaluation date or the expectation of future pretax losses and the existence and frequency of prior cumulative pretax losses.

---

We utilize a rolling twelve quarters of pre-tax income or loss as a measure of our cumulative results in recent years. Concluding that a valuation allowance is not required is difficult when there is significant negative evidence which is objective and verifiable, such as cumulative losses in recent years. However, a cumulative three year loss is not solely determinative of the need for a valuation allowance. We also consider all other available positive and negative evidence in our analysis.

Other factors considered in the determination of the probability of the realization of the deferred tax assets include, but are not limited to:

The Company assesses available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. A significant piece of objective negative evidence is recent pretax losses and/or expectations of future pretax losses. Such objective evidence limits the ability to consider other subjective evidence including projections for future growth. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as our projections for growth.

See Note 7 of Notes to Consolidated Financial Statements for additional detail on the valuation allowance.

Pension Plan Accounting Assumptions

We are required to make a number of assumptions in estimating the future benefit obligations for, and fair value of assets included in, our pension plans, which impact the amount of liability and net periodic pension cost recognized related to our plans. These include assumptions for applicable discount rates, the expected rate of return on plan assets and the rate of future employee compensation increases. See Note 6 of Notes to Consolidated Financial Statements for more information on the accounting for our pension plans and the related assumptions.

New Accounting Pronouncements

Accounting Standard Updates that Became Effective in the Current Period

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, amending reportable segment disclosure requirements to include disclosure of incremental segment information on an annual and interim basis. Among the disclosure enhancements are new disclosures regarding significant segment expenses that are regularly provided to the chief operating decision-maker and included within each reported measure of segment profit or loss, as well as other segment items bridging segment revenue to each reported measure of segment profit or loss. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, and are applied retrospectively. We retrospectively adopted the segment disclosures required under these amended in the year ended December 31, 2024 consolidated financial statements, with no changes to our previously disclosed reportable segments.

Accounting Standard Updates to Become Effective in Future Periods

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures, amending income tax disclosure requirements for the effective tax rate reconciliation and income taxes paid. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024 and are applied prospectively. Early adoption and retrospective application of the amendments are permitted. As the amendments apply to income tax disclosures only, the Company does not expect adoption to have a material impact on our consolidated financial statements and disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures, which includes amendments to require the disclosure of certain specific costs and expenses that are included

---

in a relevant expense caption on the face of the income statement. Specific costs and expenses that would be required to be disclosed include: purchases of inventory, employee compensation, depreciation and intangible asset amortization. Additionally, a qualitative description of other items is required, equal to the difference between the relevant expense caption and the separately disclosed specific costs. The amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, and are applied retrospectively. The Company is evaluating the impact of the amendments on our consolidated financial statements and disclosures.

Guaran tor Subsidiaries

Presented below are Hecla’s condensed consolidating financial statements as required by Rule 3-10 of Regulation S-X of the Securities Exchange Act of 1934, as amended, resulting from the guarantees by certain of Hecla's subsidiaries of the Senior Notes and IQ Notes (see Note 9 of Notes to Consolidated Financial Statements for more information). As of December 31, 2024, the Guarantors consist of the following Hecla 100%-owned subsidiaries: Hecla Limited; Silver Hunter Mining Company; Rio Grande Silver, Inc.; Hecla MC Subsidiary, LLC; Hecla Silver Valley, Inc.; Burke Trading, Inc.; Hecla Montana, Inc.; Revett Silver Company; RC Resources, Inc.; Troy Mine Inc.; Revett Exploration, Inc.; Revett Holdings, Inc.; Mines Management, Inc.; Newhi, Inc.; Montanore Minerals Corp.; Hecla Alaska LLC; Hecla Greens Creek Mining Company; Hecla Admiralty Company; Hecla Juneau Mining Company; Klondex Holdings Inc.; Klondex Gold & Silver Mining Co.; Klondex Midas Holdings Limited; Klondex Aurora Mine Inc.; Klondex Hollister Mine Inc.; Hecla Quebec, Inc.; and Alexco Resource Corp. We completed the offering of the Senior Notes on February 19, 2020 under our shelf registration statement previously filed with the SEC. We issued the IQ Notes in four equal tranches between July and October 2020.

The condensed consolidating financial statements below have been prepared from our financial information on the same basis of accounting as the consolidated financial statements set forth elsewhere in this report. Investments in the subsidiaries are accounted for under the equity method. Accordingly, the entries necessary to consolidate Hecla, the Guarantors, and our non-guarantor subsidiaries are reflected in the eliminations column. In the course of preparing consolidated financial statements, we eliminate the effects of various transactions conducted between Hecla and its subsidiaries and among the subsidiaries. While valid at an individual subsidiary level, such activities are eliminated in consolidation because, when taken as a whole, they do not represent business activity with third-party customers, vendors, and other parties. Examples of such eliminations include the following:

---

Separate financial statements of the Guarantors are not presented because the guarantees by the Guarantors are joint and several and full and unconditional, except for certain customary release provisions, including: (1) the sale or disposal of all or substantially all of the assets of the Guarantor; (2) the sale or other disposition of the capital stock of the Guarantor; (3) the Guarantor is designated as an unrestricted entity in accordance with the applicable provisions of the indenture; (4) Hecla ceases to be a borrower as defined in the indenture; and (5) upon legal or covenant defeasance or satisfaction and discharge of the indenture.

Forward-Looking Statements

---

The foregoing discussion and analysis, as well as certain information contained elsewhere in this report, contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act, and are intended to be covered by the safe harbor created thereby. See the discussion in Special Note on Forward-Looking Statements included prior to Item 1 .

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The following discussion about our exposure to market risks and risk-management activities includes forward-looking statements that involve risk and uncertainties, as well as summarizes the financial instruments held by us at December 31, 2024 which are sensitive to changes in commodity prices, foreign exchange rates and interest rates and are not held for trading purposes. Actual results could differ materially from those projected in the forward-looking statements. In the normal course of business, we also face risks that are either non-financial or non-quantifiable (see Item 1A. Risk Factors above).

Metals Prices

Changes in the market prices of silver, gold, lead and zinc can significantly affect our profitability and cash flow. As discussed in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Estimates , metals prices can fluctuate due to numerous factors beyond our control. As discussed below, we utilize financially-settled forward and put option contracts to manage our exposure to changes in prices for silver, gold, zinc and lead.

Provisional Sales

Sales of all metals products sold directly to customers, including by-product metals, are recorded as revenues when all performance obligations have been completed and the transaction price can be determined or reasonably estimated. For concentrate sales, revenues are generally recorded at the time of shipment at forward prices for the estimated month of settlement. Due to the time elapsed between shipment to the customer and the final settlement with the customer we must estimate the prices at which sales of our metals will be settled. Previously recorded sales are adjusted to estimated settlement metals prices until final settlement by the customer. Changes in metals prices between shipment and final settlement will result in changes to revenues previously recorded upon shipment. Metals prices can and often do fluctuate widely and are affected by numerous factors beyond our control (see Item 1A. Risk Factors – A substantial or extended decline in metals prices would have a material adverse effect on us ). At December 31, 2024, metals contained in concentrate sales and exposed to future price changes totaled approximately 1.5 million ounces of silver, 2,000 ounces of gold, 39,150 tons of zinc, and 52,350 tons of lead. If the price for each metal were to change by 10%, the change in the total value of the concentrates sold would be approximately $28.6 million. However, as discussed in Commodity-Price Risk Management below, at times, subject to management's discretion, we utilize a program designed and intended to mitigate the risk of price adjustments with limited mark-to-market financially-settled forward contracts for our silver, gold, zinc and lead sales. Therefore, the impact of changes in prices on the value of concentrates sold would be substantially offset by a gain or loss on forward contracts to the extent such contracts are utilized.

Commodity-Price Risk Management

We may at times use commodity forward sales commitments, commodity swap contracts and commodity put and call option contracts to manage our exposure to fluctuation in the prices of certain metals we produce. Contract positions are designed to ensure that we will receive a defined minimum price for certain quantities of our production, thereby partially offsetting our exposure to fluctuations in market prices. Our risk management policy allows for up to 75% of our planned metals price exposure for five years into the future, with certain other limitations, to be covered under such programs that would establish a ceiling for prices to be realized on future sales. These instruments do, however, expose us to (i) credit risk in the event of non-performance by counterparties for contracts in which the contract price exceeds the spot price of a commodity and (ii) price risk to the extent that the spot price exceeds the contract price for quantities of our production covered under contract positions.

We are currently using financially-settled forward contracts to manage the exposure to changes in prices of silver, gold, zinc and lead contained in our concentrate shipments between the time of shipment and final settlement. In addition, we are using financially-settled forward contracts to manage the exposure to changes in prices of zinc and lead (but not silver and gold) contained in our forecasted future concentrate shipments. The following tables summarize the quantities of metals committed under forward sales contracts at December 31, 2024 and 2023:

We designate the contracts for lead and zinc contained in our forecasted future shipments as hedges for accounting purposes, with gains and losses deferred to accumulated other comprehensive loss until the hedged product ships. The forward contracts for silver and gold contained in our concentrate shipments have not been designated as hedges and are marked-to-market through earnings each period.

At December 31, 2024 and 2023, we recorded the following balances for the fair value of forward contracts held at that time (in millions):

		December 31, 2024												December 31, 2023
Balance sheet line item:		Contracts in an asset position				Contracts in a liability position				Net asset (liability)				Contracts in an asset position				Contracts in a liability position				Net asset (liability)
Other current assets		$	11.5			$	—			$	11.5			$	3.1			$	—			$	3.1
Other non-current assets		$	6.6			$	—			$	6.6			$	1.5			$	—			$	1.5
Current derivatives liability		$	—			$	—			$	—			$	—			$	(0.1	)		$	(0.1	)

Net realized and unrealized gains of approximately $13.4 million related to the effective portion of the contracts designated as hedges were included in accumulated other comprehensive loss as of December 31, 2024. Realized and unrealized gains and losses will be transferred from accumulated other comprehensive loss to current earnings as the underlying forecasted sales transaction is recognized. We estimate approximately $7.9 million in net realized and unrealized gains included in accumulated other comprehensive loss as of December 31, 2024 will be reclassified to current earnings in the next twelve months. The realized gains arose due to cash settlement of zinc and lead contracts in 2023 and zinc contracts in 2022 prior to maturity for cash proceeds of $8.5 million and $17.4 million, respectively.

We recognized a net gain of $1.3 million, including a $11.4 million gain transferred from accumulated other comprehensive income (loss), during 2024 on the contracts utilized to manage exposure to prices of metals in our concentrate shipments, which is included in sales. The net gain recognized on the contracts offsets loss related to price adjustments on our provisional concentrate sales, both of which resulted from changes to silver, gold, lead and zinc prices between the time of sale and final settlement. The net losses and gains recognized on the contracts offset gains and losses related to price adjustments on our provisional concentrate sales due to changes to silver, gold, lead and zinc prices between the time of sale and final settlement.

We recognized a net gain of $19.7 million during 2023, including a $20.6 million gain transferred from accumulated other comprehensive income (loss), on the contracts utilized to manage exposure to prices of metals in our concentrate shipments, which is included in sales. The net gain recognized on the contracts offsets loss related to price adjustments on our provisional concentrate sales, both of which resulted from changes to silver, gold, lead and zinc prices between the time of sale and final settlement.

We recognized a net loss of $5.8 million, including a $6.0 million loss transferred from accumulated other comprehensive income (loss), during 2022 on the contracts utilized to manage exposure to prices of metals in our concentrate shipments, which is included in sales of products and other income. The net loss recognized on the contracts offsets gains related to price adjustments on our provisional concentrate sales, both of which resulted from changes to silver, gold, lead and zinc prices between the time of sale and final settlement.

Foreign Currency

We operate or have mining interests in Canada, which exposes us to risks associated with fluctuations in the exchange rates between the USD and CAD. We have determined the functional currency for our Canadian operations is the USD. As such, foreign exchange gains and losses associated with the re-measurement of monetary assets and liabilities from CAD to USD are recorded to earnings each period. For the year ended December 31, 2024, we recognized a net foreign exchange gain of $7.6 million. Foreign currency exchange rates are influenced by a number of factors beyond our control. A 10% change in the exchange rate between the USD and CAD from the rate at December 31, 2024 would have resulted in a change of approximately $7.5 million in our net foreign exchange gain or loss.

We utilize a program to manage our exposure to fluctuations in the exchange rate between the USD and CAD and the impact on our future operating costs denominated in CAD. In November 2021, we initiated a similar program related to future development costs denominated in CAD, and have used a similar program, on a limited basis, related to interest payments on our IQ Notes (see Note 9 of Notes to Consolidated Financial Statements). The programs utilize forward contracts to buy CAD. Each contract related to operating costs is designated as a cash flow hedge, while contracts related to development and interest costs have not been designated as hedges as of December 31, 2024. Our risk management policy allows for up to 75% of our planned cost exposure for five years into the future to be covered under such programs, and for potential additional programs to manage other foreign currency-related exposure areas. These instruments do, however, expose us to (i) credit risk in the form of non-performance by counterparties for contracts in which the contract exchange rate exceeds the spot exchange rate of a currency and (ii) exchange rate risk to the extent that the spot exchange rate exceeds the contract exchange rate for amounts of our operating costs covered under contract positions. As of December 31, 2024, we have a total of 378 forward contracts outstanding to buy a total of CAD $279.3 million having a notional amount of USD$206.6 million with CAD-to-USD exchange rates ranging between 1.2816 and 1.4223, with the following exposures from 2025-2026:

As of December 31, 2024 and 2023, we recorded the following balances for the fair value of the contracts (in millions):

		December 31,

Other current assets		$	—			$	2.7
Other non-current assets		$	—			$	2.0

Net unrealized losses of approximately $8.0 million related to the effective portion of the hedges were included in accumulated other comprehensive income (loss) as of December 31, 2024. Unrealized gains and losses will be transferred from accumulated other comprehensive loss to current earnings as the underlying operating expenses are recognized. We estimate approximately $6.0 million in net unrealized losses included in accumulated other comprehensive income (loss) as of December 31, 2024 would be reclassified to current earnings in the next twelve months.

Net realized losses of approximately $3.8 million on contracts related to underlying expenses which have been recognized were transferred from accumulated other comprehensive loss and included in cost of sales and other direct production costs for the year ended December 31, 2024. Net unrealized losses of approximately $5.7 million related to contracts not designated as hedges and no net unrealized gains or losses related to ineffectiveness of the hedges were included in fair value adjustments, net on our consolidated statements of operations and comprehensive (loss) income for the year ended December 31, 2024.

Net realized losses of approximately $3.6 million on contracts related to underlying expenses which have been recognized were transferred from accumulated other comprehensive loss and included in cost of sales and other direct production costs for the year ended December 31, 2023. Net unrealized gains of approximately $1.2 million related to contracts not designated as hedges and no net unrealized gains or losses related to ineffectiveness of the hedges were included in fair value adjustments, net on our consolidated statements of operations and comprehensive (loss) income for the year ended December 31, 2023.

Net realized gains of approximately $0.8 million on contracts related to underlying expenses which have been recognized were transferred from accumulated other comprehensive loss and included in cost of sales and other direct production costs for the year ended December 31, 2022. Net unrealized gains of approximately $0.1 million related to contracts not designated as hedges and no net unrealized gains or losses related to ineffectiveness of the hedges were included in fair value adjustments, net on our consolidated statements of operations and comprehensive income (loss) for the year ended December 31, 2022.

Interest Rates

We have a $225.0 million credit facility, and amounts drawn on the facility are subject to variable rates of interest based on a spread over the London Interbank Offered Rate or an alternative base rate. Interest rates fluctuate due to economic factors beyond our control. As of December 31, 2024, we had $23.0 million drawn under the facility and $6.2 million for letters of credit. Assuming all revolving loans currently available to us were fully drawn, each one percentage point change in interest rates would result in a $2.2 million change in annual cash interest expense on our credit facility. See Note 9 of Notes to Consolidated Financial Statements for more information on our credit facility.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over our financial reporting, which is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America.

---

Because of its inherent limitations, any system of internal control over financial reporting, no matter how well designed, may not prevent or detect misstatements due to the possibility that a control can be circumvented or overridden or that misstatements due to error or fraud may occur that are not detected. Also, because of changes in conditions, internal control effectiveness may vary over time.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2024, using criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and concluded that we have maintained effective internal control over financial reporting as of December 31, 2024, based on these criteria.

Our internal control over financial reporting as of December 31, 2024 has been audited by BDO USA, P.C., an independent registered public accounting firm, as stated in the attestation report which is included herein.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Indepen dent Registered Public Accounting Firm

Shareholders and Board of Directors

Hecla Mining Company

Coeur d’Alene, Idaho

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Hecla Mining Company (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations and comprehensive income (loss), changes in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2024, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and our report dated February 13, 2025 expressed an unqualified opinion thereon.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Impairment of Long-Lived Assets – Casa Berardi

As described in Notes 2 and 15 to the consolidated financial statements, management reviews and evaluates the net carrying value of all properties and facilities, including idle facilities, upon the occurrence of events or changes in circumstances that indicate that the related carrying amounts may not be recoverable. Tests for recoverability of the property is based on the probability adjusted undiscounted expected future cash flows that will be generated from operations.

We identified the assessment of the recoverability of the Company’s properties and facilities at Casa Berardi as a critical audit matter, specifically certain assumptions used in the underlying estimate of probability adjusted undiscounted expected future cash flows. These assumptions include metals to be recovered from proven and probable mineral reserves, future production, potential estimated sales value and estimated metals prices over the estimated remaining mine life. Auditing these assumptions involved especially challenging and subjective auditor judgment due to the nature and extent of audit effort required to address this matter. The audit effort also involved the use of professionals with specialized skill and knowledge to assist in performing these procedures and evaluating the audit evidence obtained.

The primary procedures we performed to address this critical audit matter included:
