Special Note on Forward-Looking Statements

Certain statements contained in this report (including information incorporated by reference) are “forward-looking statements” and are intended to be covered by the safe harbor provided for under Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended ("Exchange Act"). Our forward-looking statements include our current expectations and projections about future production, results, performance, prospects and opportunities, including reserves and other mineralization. We have tried to identify these forward-looking statements by using words such as “may,” “might,” “will,” “expect,” “anticipate,” “believe,” “could,” “intend,” “plan,” “estimate” and similar expressions. These forward-looking statements are based on information currently available to us and are expressed in good faith and believed to have a reasonable basis. However, our forward-looking statements are subject to a number of risks, uncertainties and other factors that could cause our actual production, results, performance, prospects or opportunities, including reserves and mineralization, to differ materially from those expressed in, or implied by, these forward-looking statements.

These risks, uncertainties and other factors include, but are not limited to, those set forth under Item 1A. Risk Factors and Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. Given these risks and uncertainties, readers are cautioned not to place undue reliance on our forward-looking statements. Projections and other forward-looking statements included in this report have been prepared based on assumptions, which we believe to be reasonable, but not in accordance with United States generally accepted accounting principles (“GAAP”) or any guidelines of the Securities and Exchange Commission (“SEC”). Actual results may vary, perhaps materially. You are strongly cautioned not to place undue reliance on such projections and other forward-looking statements. All subsequent written and oral forward-looking statements attributable to Hecla Mining Company or to persons acting on our behalf are expressly qualified in their entirety by these cautionary statements. Except as required by federal securities laws, we disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

PART I

Item 1. Business

For information regarding the organization of our business segments and our significant customers, see Note 11 of Notes to Consolidated Financial Statements.

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

Introduction

Hecla Mining Company and our subsidiaries have provided precious and base metals to the U.S. and worldwide 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, develop, and produce silver, gold, lead and zinc. In doing so, we intend to manage our business activities in a safe, environmentally responsible and cost-effective manner.

We produce lead, zinc and bulk concentrates, which we sell to custom smelters and brokers, and unrefined precipitate and bullion bars (doré) containing gold and silver, which are further refined before sale to precious metals traders. We are organized and managed in four segments that encompass our operating units: the Greens Creek, Lucky Friday, Casa Berardi, and San Sebastian units.

Table of Contents

The map below shows the locations of our operating units and our exploration and pre-development projects, as well as our corporate offices located in Coeur d’Alene, Idaho, Vancouver, British Columbia and Val d'Or, Quebec.

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

| • | Operating our properties safely, in an environmentally responsible manner, and cost-effectively.

| • | Continue optimizing and improving operations at our Greens Creek, Lucky Friday, Casa Berardi, and San Sebastian units.

| • | Expanding our proven and probable reserves and production capacity at our operating properties.

| • | Conducting our business with financial stewardship to preserve our financial position in varying metals price environments.

| • | Advancing permitting of the Rock Creek and Montanore projects. We acquired Rock Creek as part of the acquisition of Revett Mining Company ("Revett") in June 2015, and we acquired Montanore through the acquisition of Mines Management, Inc. ("Mines Management") in September 2016.

| • | Maintaining and investing in exploration and pre-development projects in the vicinities of six mining districts and projects we believe to be under-explored and under-invested: North Idaho's Silver Valley in the historic Coeur d'Alene Mining District; our Greens Creek unit on Alaska's Admiralty Island located near Juneau; the silver-producing district near Durango, Mexico; the Abitibi region of north-western Quebec, Canada; the Rock Creek and Montanore projects in northwestern Montana; and the Creede district of Southwestern Colorado.

| • | Continuing to seek opportunities to acquire and invest in mining and exploration properties and companies.

Below is a summary of net income (loss) for each of the last five years (in thousands):

|  | Year Ended December 31, |

See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Results of Operations for a summary of average market and realized prices for each of the three years ended December 31, 2016, 2015 and 2014. Our results of operations are significantly impacted by fluctuations in the prices of silver, gold, lead and zinc, which are affected by numerous factors beyond our control. See Item 1A. Risk Factors – Financial Risks – A substantial or extended decline in metals prices would have a material adverse effect on us for information on a number of the various factors that can impact prices of the metals we produce. Our average realized prices for silver, gold, zinc and lead were higher in 2016 compared to 2015, and were lower in 2015 compared to 2014. Market metal price trends are a significant factor in our operating and financial performance. We are unable to predict fluctuations in prices for metals and have limited control over the timing of our concentrate shipments which impacts our realized prices. However, we utilize financially-settled forward contracts for lead and zinc with the objective of managing the exposure to changes in prices of lead and zinc contained in our concentrate shipments between the time of sale and final settlement. In addition, we utilize a similar program for silver and gold with the objective of managing exposure to changes in prices for those metals contained in our concentrate shipments. See Note 10 of Notes to Consolidated Financial Statements for more information on our base and precious metal forward contract programs.

| • | Cost of sales and other direct production costs of $339.0 million in 2016, $293.6 million in 2015, $304.4 million in 2014, $235.3 million in 2013 and $134.1 million in 2012. Cost of sales and other direct production costs in 2016 were impacted by commencement of sales at our San Sebastian unit in the first quarter of 2016. During 2012 and 2013, costs of sales and other direct production costs were impacted by the temporary suspension of production at the Lucky Friday mine during most of 2012 and by the acquisition of the Casa Berardi mine during 2013. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Results of Operations for more information.

| • | $25.3 million in suspension-related costs at our Lucky Friday unit in 2012, including $6.3 million in depreciation, depletion, and amortization. We recognized suspension-related income of $1.4 million in 2013 due to the receipt of business interruption insurance proceeds related to the suspension period. Limited production recommenced at the Lucky Friday unit in the first quarter of 2013, and the mine resumed full production in September 2013.

Table of Contents

| • | Exploration and pre-development expenditures totaling $17.9 million, $22.0 million, $19.7 million, $37.7 million and $49.7 million for the years ended December 31, 2016, 2015, 2014, 2013 and 2012, respectively.

| • | Provision for closed operations and environmental matters of $5.7 million, $12.2 million, $10.1 million, $5.4 million and $4.7 million for the years ended December 31, 2016, 2015, 2014, 2013, and 2012, respectively.

| • | Net gains on base metal forward contracts of $4.4 million in 2016, $8.3 million in 2015, $9.1 million in 2014, and $18.0 million in 2013, and a net loss of $10.5 million in 2012. These losses and gains are related to financially-settled forward contracts on forecasted zinc and lead production as part of a risk management program initiated in 2010. See Note 10 of Notes to Consolidated Financial Statements for more information on our derivatives contracts.

| • | Our acquisition of Aurizon Mines Ltd. ("Aurizon") for $714.5 million in June 2013, which was partially funded by the issuance of 6.875% Senior Notes due 2021 ("Senior Notes") in April 2013 for net proceeds of $490.0 million. We recognized expenses relating to the Aurizon acquisition of $26.4 million in 2013. In addition, in 2016, 2015 and 2014, respectively, we recorded interest expense related to the Senior Notes, including amortization of issuance costs, of $20.1 million, $22.7 million and $24.6 million, net of $16.2 million, $13.5 million and $11.8 million in capitalized interest.

| • | Our acquisition of Mines Management for $52.1 million in September 2016. We recognized expenses related to the acquisition of $2.7 million in 2016. See Note 15 of Notes to Consolidated Financial Statements for more information.

| • | Our acquisition of Revett for $20.1 million in June 2015. We recognized expenses related to the acquisition of $2.2 million in 2015. See Note 15 of Notes to Consolidated Financial Statements for more information.

| • | Foreign exchange loss in 2016, and gains in 2015, 2014, and 2013, of $2.9 million, $24.6 million, $11.5 million and $3.0 million, respectively, primarily due to increased exposure to exchange fluctuations between the U.S. dollar and Canadian dollar as a result of our acquisition of Aurizon.

| • | Income tax provisions of $27.4 million, $56.3 million and $8.9 million in 2016, 2015 and 2012, respectively, and income tax benefits of $5.2 million and $9.8 million in 2014 and 2013, respectively. The provision in 2016 was primarily the result of reporting pre-tax net income, partially offset by a benefit from a reduction in the valuation allowance for deferred tax assets. See Note 5 of Notes to Consolidated Financial Statements for more information.

| • | An increase in the number of shares of our common stock outstanding, which impacts our income (loss) per common share.

A comprehensive discussion of our financial results for the years ended December 31, 2016, 2015 and 2014, individual operating unit performance, general corporate expenses 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. We produce zinc, lead and bulk flotation concentrates at our Greens Creek unit and lead and zinc flotation concentrates at our Lucky Friday unit, each of which we sell to custom smelters and brokers on contract. The flotation concentrates produced at our Greens Creek and Lucky Friday units contain payable silver, zinc and lead, and at Greens Creek they also contain payable gold. At Greens Creek, we also produce gravity concentrate containing silver, gold and lead. Unrefined bullion (doré) is produced from the gravity concentrate by a third party processor and sold to a precious metal refiner. We also produce unrefined gold and silver bullion bars (doré) at Casa Berardi and San Sebastian, which are shipped to refiners before sale of the metals to precious metals traders. Payable metals are those included in our products which we are paid for by smelters, brokers and refiners. Our segments as of December 31, 2016 included:

| • | The Greens Creek unit located on Admiralty Island, near Juneau, Alaska. Greens Creek is 100% owned and has been in production since 1989, with a temporary care and maintenance period from April 1993 through July 1996.

| • | The Lucky Friday unit located in northern Idaho. Lucky Friday is 100% owned and has been a producing mine for us since 1958. Production at the Lucky Friday unit returned to historical levels in September 2013 following a period of rehabilitation and no production in 2012.

| • | The Casa Berardi unit located in the Abitibi region of north-western Quebec, Canada. Casa Berardi is 100% owned and was acquired on June 1, 2013 with the purchase of all issued and outstanding common shares of Aurizon. Aurizon had operated and produced from the Casa Berardi mine since late 2006 and began various mine enhancements in an effort to improve operational efficiency, including a shaft deepening project completed in 2014 and a new paste fill facility completed in 2013.

| • | The San Sebastian unit located in the state of Durango, Mexico. San Sebastian is 100% owned, and had previously produced for us from underground mines between 2001 and 2005. Recent near-surface exploration discoveries in the vicinity of the past producing area led to the decision in the third quarter of 2015 to develop shallow open pit mines there. Production commenced from the open pits in the fourth quarter of 2015.

The contributions to our consolidated sales by our operating units in 2016 were 40.3% from Greens Creek, 27.4% from Casa Berardi, 17.6% from San Sebastian, and 14.7% from Lucky Friday. Commercial production commenced at San Sebastian in the fourth quarter of 2015, with the first sales made there in the first quarter of 2016.

The table below summarizes our production for the years ended December 31, 2016, 2015 and 2014. Zinc and lead production quantities are presented in short tons (“tons”).

|  | Year |
|  | 2016 |  |  | 2015 |  |  | 2014 |
Silver (ounces) |  |  | 17,177,317 |  |  |  | 11,591,603 |  |  |  | 11,090,506 |
Gold (ounces) |  |  | 233,929 |  |  |  | 189,327 |  |  |  | 186,997 |

Zinc (tons) |  |  | 68,516 |  |  |  | 70,073 |  |  |  | 67,969 |

Licenses, Permits and Claims/Concessions

We are required to obtain various licenses and permits to operate our mines and conduct exploration and reclamation activities. The suspension in production at the Lucky Friday unit during 2012 was pursuant to an order from the Federal Mine Safety and Health Administration. See Item 1A. Risk Factors - Legal, Market and Regulatory Risks - We are required to obtain governmental permits and other approvals in order to conduct mining operations. Further, each of our Rock Creek and Montanore projects can only be developed if we are successful in obtaining the necessary permits. See Item 1A. Risk Factors - Legal, Market and Regulatory Risks - Legal challenges could prevent the Rock Creek or Montanore projects from ever being developed. In addition, our operations and exploration activities at our Casa Berardi and San Sebastian units are conducted pursuant to claims or concessions granted by the host government, and otherwise 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 - Operation, Development, Exploration and Acquisition Risks - Our foreign activities are subject to additional inherent risks.

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 ore reserves. At December 31, 2016, the book value of our properties, plants, equipment and mineral interests, net of accumulated depreciation, was approximately $2.0 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. See Item 1A. Risk Factors - Operation, Development, Exploration and Acquisition Risks - Our operations may be adversely affected by risks and hazards associated with the mining industry that may not be fully covered by insurance.

Employees

As of December 31, 2016, we employed 1,396 people, and we believe relations with our employees are generally good.

Many of the employees at our Lucky Friday unit are represented by a union. The most recent collective bargaining agreement with workers at our Lucky Friday unit expired on April 30, 2016, and on February 19, 2017, the unionized employees voted against our contract offer. We expect further discussions with the union but it is possible that an agreement will not be reached, in which case we cannot predict what might happen next, including what actions we or the union might take in response to failing to reach an agreement.

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 risks could materially adversely affect our business, financial condition or operating results and could decrease the value of our common or preferred stock or other outstanding securities.

Financial Risks

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

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

| • | speculative activities;

Table of Contents

| • | relative exchange rates of the U.S. dollar;

| • | global and regional demand and production;

| • | political instability;

| • | inflation, recession or increased or reduced economic activity; and

| • | other political, regulatory and economic conditions.

These factors are largely beyond our control and are difficult to predict. If the market prices for these metals fall below our production, exploration or development costs for a sustained period of time, we will experience losses and may have to discontinue exploration, development or operations, or 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 and zinc for the last five years. On February 20, 2017, the closing prices for silver, gold, lead and zinc were $18.06 per ounce, $1,238 per ounce, $1.03 per pound and $1.30 per pound, respectively.

We have had losses that could reoccur in the future.

We have had volatility in our net income (loss) reported in the last five years, as shown in Item 6. Selected Financial Data, including net losses of $87.0 million in 2015 and $25.1 million in 2013. 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; 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; 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 foresee whether our operations will continue to generate sufficient revenue in order for us to generate net cash from operating activities. There can be no assurance that we will not experience net losses in the future.

Our level of debt could impair our financial health and prevent us from fulfilling our obligations under our current debt obligations.

As of December 31, 2016, we had total debt of approximately $512.9 million and our total cash and cash equivalents was $169.8 million. We had net income of $69.5 million in 2016, which included $21.8 million incurred for debt service obligations, net of amounts capitalized, which was primarily for interest on our Senior Notes. Our level of debt and our debt service obligations could:

| • | make it difficult for us to satisfy our current debt obligations;

| • | reduce the amount of funds available to finance our operations, capital expenditures and other activities;

| • | increase our vulnerability to economic downturns and industry conditions;

7

Table of Contents

• limit our flexibility in responding to changing business and economic conditions, including increased competition;

| • | place us at a disadvantage when compared to our competitors that have lower leverage;

| • | increase our cost of borrowing; and

| • | limit our ability to borrow additional funds.

We and/or our subsidiaries may be able to incur substantial additional debt in the future. Although the indenture governing our outstanding Senior Notes contains restrictions on the incurrence of additional debt, these restrictions are subject to a number of significant qualifications and exceptions and, under certain circumstances, the amount of additional debt that could be incurred in compliance with these restrictions could be substantial. In addition, we have $100 million in available capacity to be drawn from our revolving credit facility, which is separate and apart from our Senior Notes indenture and also contains limitations on our ability to incur additional debt.

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. See the risk factors below under the heading “Risks Related to Our Debt.”

An extended decline in metals prices, an increase in operating or capital costs, mine accidents or closures, increasing environmental obligations, or our inability to convert exploration potential 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, 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, and recognizing impairment write-downs could negatively impact our results of operations. Metal 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 average 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 exploration potential beyond the current operating plans. We determined there were no events or changes in circumstances indicating the carrying value of our long-lived assets may not be recoverable as of December 31, 2016. However, if the prices of silver, gold, zinc and lead 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 ore reserves or exploration potential at our mining properties, we may be required to recognize asset write-downs in the future. In addition, the perceived market value of the exploration potential 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 exploration potential to reserves could significantly reduce our estimates of the value of the exploration potential at our properties and result in asset write-downs.

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 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 continuation or re-emergence of the 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.

Table of Contents

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

We periodically enter into risk management activities, such as financially-settled forward sales contracts, to manage the prices received on the metals we produce. 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 possible revenues in the event that the market price of a metal exceeds the price stated in a forward sale contracts. In addition, 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 utilize financially-settled forward contract programs to manage the exposure to changes in silver, gold, lead and zinc prices contained in our concentrate shipments between the time of sale and final settlement, and also utilize such programs to manage the exposure to changes in the prices of lead and zinc contained in our forecasted future concentrate shipments.

In 2016, we also initiated financially-settled forward contract programs to manage exposure to fluctuations in the exchange rates between the U.S. dollar ("USD") and Canadian dollar ("CAD") and Mexican peso ("MXN") and the impact on our future operating costs denominated in CAD and MXN. However, 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 or MXN compared to the exchange rates stated in the forward contracts.

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

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

Our profitability is sensitive to the costs of commodities such as fuel (in particular as used at Greens Creek to generate electricity when hydropower is unavailable), steel, and cement. While the recent prices for such commodities have been stable or in decline, prices have been historically volatile and material increases in commodity costs could have a significant effect on our results of operations.

Our accounting and other estimates may be imprecise.

Preparing 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:

| • | mineral reserves, mineralized material, and other resources that are the basis for future income and cash flow estimates and units-of-production depreciation, depletion and amortization calculations;

| • | future ore grades, throughput and recoveries;

| • | future metals prices;

| • | future capital and operating costs;

| • | environmental, reclamation and closure obligations;

| • | permitting and other regulatory considerations;

| • | asset impairments;

| • | valuation of business combinations;

9

Table of Contents

| • | future foreign exchange rates, inflation rates and applicable tax rates;

| • | reserves for contingencies and litigation; and

| • | deferred tax asset valuation allowance.

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 1 of Notes to Consolidated Financial Statements, and the risk factors set forth below: “Our costs of development of new orebodies and other capital costs may be higher and provide less return than we estimated,” “Our ore reserve estimates may be imprecise,” “Our environmental obligations may exceed the provisions we have made,” and “We are currently involved in ongoing legal disputes that may materially adversely affect us.”

Our ability to recognize the benefits of deferred tax assets is dependent on future cash flows and 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 price and production estimates are key components used in the determination of our ability to realize 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. We currently do not have deferred tax valuation allowances for certain amounts related to U.S. and foreign net operating loss carryforwards, and our deferred tax assets as of December 31, 2016 were $151.7 million, net of $99.6 million in valuation allowances. During 2016, the valuation allowance on our deferred tax assets decreased by approximately $16.2 million. See Note 5 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 most U.S. employees. Canadian employees participate in Canada's public retirement system, 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. A sustained period of low returns or losses on investments could require us to fund the pension plans to a greater extent than anticipated. See Note 8 of Notes to Consolidated Financial Statements for more information on our pension plans.

Risks Relating to Our Debt

The terms of our debt impose restrictions on our operations.

The indenture governing our Senior Notes includes a number of significant restrictive 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:

| • | make it more difficult for us to satisfy our obligations with respect to our Senior Notes and our other debt;

10

Table of Contents

| • | limit our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general corporate requirements, or require us to make divestitures;

| • | require a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, acquisitions and other general corporate purposes;

| • | increase our vulnerability to general adverse economic and industry conditions;

| • | limit our flexibility in planning for and reacting to changes in the industry in which we compete;

| • | place us at a disadvantage compared to other, less leveraged competitors; and

| • | increase our cost of borrowing additional funds.

In addition, utilization of our revolving credit facility would require us to comply with various covenants. 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 the holders of the defaulted debt 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. 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.

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 under our debt, 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. 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, certain of which are not guarantors of our debt. 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. Unless they are guarantors of our debt, our subsidiaries 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.

11

Table of Contents

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures 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.

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

Borrowings under our revolving credit facility would be at variable rates of interest and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate debt would increase even though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our debt, would correspondingly decrease. Assuming all revolving loans were fully drawn, each one percentage point change in interest rates would result in a $1.0 million change in annual cash interest expense on our credit facility.

Our Senior Notes and the guarantees thereof are effectively subordinated to any of our and our guarantors' secured debt to the extent of the value of the collateral securing that debt.

The Senior Notes and the guarantees thereof are not secured by any of our assets or the assets of our subsidiaries. The indenture governing the Senior Notes permits us to incur secured debt up to specified limits. As a result, the Senior Notes and the guarantees are effectively subordinated to our and our guarantors' future secured debt with respect to the collateral that secures such debt, including any borrowings under our revolving credit facility. Upon a default in payment on, or the acceleration of, any of our secured debt, or in the event of bankruptcy, insolvency, liquidation, dissolution, reorganization or other insolvency proceedings involving us or a guarantor, the proceeds from the sale of collateral securing any secured debt will be available to pay obligations on the Senior Notes only after such secured debt has been paid in full. As a result, the holders of the Senior Notes may receive less, ratably, than the holders of secured debt in the event of a bankruptcy, insolvency, liquidation, dissolution, reorganization or other insolvency proceeding involving us or a guarantor.

Our current credit facility allows us to draw up to $100 million on a revolving basis, all of which would be secured debt.

Our Senior Notes are structurally subordinated to all liabilities of our non-guarantor subsidiaries.

The Senior Notes are structurally subordinated to the debt and other liabilities of our subsidiaries that do not guarantee the Senior Notes, which include all of our non-domestic subsidiaries and certain other subsidiaries. These non-guarantor subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the Senior Notes, or to make any funds available therefor, whether by dividends, loans, distributions or other payments. Any right that we or the guarantors have to receive any assets of any of the non-guarantor subsidiaries upon the liquidation or reorganization of those subsidiaries, and the consequent rights of holders of Senior Notes to realize proceeds from the sale of any of those subsidiaries' assets, will be effectively subordinated to the claims of those subsidiaries' creditors, including trade creditors and holders of any preferred equity interests of those subsidiaries. Accordingly, in the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, these non-guarantor subsidiaries will pay the holders of their debts, holders of any preferred equity interests and their trade creditors before they will be able to distribute any of their assets to us or any guarantor. Unless they are guarantors of the Senior Notes or our other debt, our subsidiaries do not have any obligation to pay amounts due on the Senior Notes or our other debt or to make funds available for that purpose.

For the year ended December 31, 2016, our non-guarantor subsidiaries represented 45% of our sales of metals and 43% of our operating expenses. As of December 31, 2016, our non-guarantor subsidiaries represented 36% of our total assets and 20% of our total liabilities, including trade payables, deferred tax liabilities and royalty obligations but excluding intercompany liabilities.

Key terms of the Senior Notes will be suspended if the Senior Notes achieve investment grade ratings and no default or event of default has occurred and is continuing.

Many of the covenants in the indenture governing the Senior Notes will be suspended if the Senior Notes are rated investment grade by Standard & Poor's and Moody's, provided at such time no default or event of default has occurred and is continuing, including those covenants that restrict, among other things, our ability to pay dividends, incur debt and to enter into certain other transactions. There can be no assurance that the Senior Notes will ever be rated investment grade. However, suspension of these covenants would allow us to engage in certain transactions that would not be permitted while these covenants were in force, and the effects of any such transactions will be permitted to remain in place even if the Senior Notes are subsequently downgraded below investment grade.

We may be unable to repurchase Senior Notes and any outstanding loans under our revolving credit facility could be accelerated in the event of a change of control as required by the indenture.

Upon the occurrence of certain change of control events specified in the indenture governing the Senior Notes, holders of the Senior Notes will have the right to require us to repurchase all of the Senior Notes at a repurchase price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of repurchase. Any change of control also would constitute a default under our revolving credit facility. Therefore, upon the occurrence of a change of control, the lenders under our revolving credit facility would have the right to accelerate any outstanding loans and, if so accelerated, we would be required to repay all of our outstanding obligations under such facility. We may not be able to pay the Senior Note holders the required price for their notes at that time because we may not have available funds to pay the repurchase price. In addition, the terms of other existing or future debt may prevent us from paying the Senior Note holders. There can be no assurance that we would be able to repay such other debt or obtain consents from the holders of such other debt to repurchase the Senior Notes. Any requirement to offer to purchase any Senior Notes may result in us having to refinance our outstanding debt, which we may not be able to do. In addition, even if we were able to refinance our outstanding debt, such financing may be on terms unfavorable to us.

Holders of the Senior Notes may not be able to determine when a change of control giving rise to their right to have the Senior Notes repurchased has occurred following a sale of "substantially all" of our assets.

The definition of change of control in the indenture governing the Senior Notes includes a phrase relating to the sale of "all or substantially all" of our assets. There is no precise established definition of the phrase "substantially all" under applicable law. Accordingly, the ability of a holder of Senior Notes to require us to repurchase its notes as a result of a sale of less than all our assets to another person may be uncertain.

Federal and state fraudulent transfer laws may permit a court to void the Senior Notes or any of the guarantees thereof, and if that occurs, holders of the Senior Notes may not receive any payments.

Federal and state fraudulent transfer and conveyance statutes may apply to the issuance of the Senior Notes and the incurrence of any guarantees of the Senior Notes. Under federal bankruptcy law and comparable provisions of state fraudulent transfer or conveyance laws, which may vary from state to state, the Senior Notes or any guarantees thereof could be voided as a fraudulent transfer or conveyance if we or any existing or future subsidiary guarantors, as applicable, (a) issued the Senior Notes or incurred such guarantee with the intent of hindering, delaying or defrauding creditors or (b) received less than reasonably equivalent value or fair consideration in return for either issuing the Senior Notes or incurring the guarantee and, in the case of (b) only, one of the following is also true at the time thereof:

| • | we or the subsidiary guarantor, as applicable, were insolvent or rendered insolvent by reason of the issuance of the Senior Notes or the incurrence of the guarantee;

13

Table of Contents

| • | the issuance of the Senior Notes or the incurrence of the guarantee left us or the subsidiary guarantor, as applicable, with an unreasonably small amount of capital or assets to carry on the business; or

| • | we or the subsidiary guarantor intended to, or believed that we or such subsidiary guarantor would, incur debts beyond our or such subsidiary guarantor's ability to pay as they mature.

As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or a valid antecedent debt is satisfied. A court would likely find that any subsidiary guarantor did not receive reasonably equivalent value or fair consideration for its guarantee to the extent such subsidiary guarantor did not obtain a reasonably equivalent benefit from the issuance of the Senior Notes.

We cannot be certain as to the standards a court would use to determine whether or not we or any subsidiary guarantor were insolvent at the relevant time or, regardless of the standard that a court uses, whether the Senior Notes or any guarantees would be subordinated to our or any subsidiary guarantor's other debt. In general, however, a court would deem an entity insolvent if:

| • | the sum of its debts, including contingent and unliquidated liabilities, was greater than the fair saleable value of all of its assets;

| • | the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or

| • | it could not pay its debts as they became due.

The subsidiary guarantees contain a "savings clause" intended to limit the subsidiary guarantor's liability to the maximum amount that it could incur without causing the incurrence of obligations under its subsidiary guarantee to be a fraudulent transfer. This provision may not be effective to protect any subsidiary guarantees from being avoided under fraudulent transfer law. Furthermore, in Official Committee of Unsecured Creditors of TOUSA, Inc. v Citicorp North America, Inc., the U.S. Bankruptcy Court in the Southern District of Florida held that a savings clause similar to the savings clause used in the indenture was unenforceable. As a result, the subsidiary guarantees were found to be fraudulent conveyances. The United States Court of Appeals for the Eleventh Circuit recently affirmed the liability findings of the Bankruptcy Court without ruling directly on the enforceability of savings clauses generally. If the TOUSA decision were followed by other courts, the risk that the guarantees would be deemed fraudulent conveyances would be significantly increased.

To the extent that any subsidiary guarantee is avoided, then, as to that subsidiary, the guaranty would not be enforceable.

If a court were to find that the issuance of the Senior Notes or the incurrence of any guarantee was a fraudulent transfer or conveyance, the court could void the payment obligations under the Senior Notes or such guarantee, could subordinate the Senior Notes or such guarantee to presently existing and future debt of ours or of the related subsidiary guarantor or could require the holders of the Senior Notes to repay any amounts received with respect to such guarantee. In the event of a finding that a fraudulent transfer or conveyance occurred, holders of the Senior Notes may not receive any repayment. Further, the avoidance of the Senior Notes could result in an event of default with respect to our and our subsidiaries' other debt that could result in acceleration of that debt.

Finally, as a court of equity, the bankruptcy court may subordinate the claims in respect of the Senior Notes to other claims against us under the principle of equitable subordination if the court determines that (1) the holders of the Senior Notes engaged in some type of inequitable conduct, (2) the inequitable conduct resulted in injury to our other creditors or conferred an unfair advantage upon the holders of Senior Notes and (3) equitable subordination is not inconsistent with the provisions of the Bankruptcy Code.

Table of Contents

Our credit ratings may not reflect all risks associated with an investment in our Senior Notes.

Credit rating agencies rate our debt securities on factors that include our results of operations, actions that we take, their view of the general outlook for our industry and their view of the general outlook for the economy. Actions taken by the rating agencies can include maintaining, upgrading, or downgrading the current rating or placing us on a watch list for possible future downgrading. At February 20, 2017, our Senior Notes were rated “B-" with a positive outlook by Standard and Poor’s, and were rated “B3" with a stable outlook by Moody’s Investors Service. In February 2016, Standard and Poor's lowered their rating of our Senior Notes from a previous "B" rating. In January 2016, Moody's indicated that they had placed us, along with other mining companies, on review for downgrade. Downgrading the credit rating of our debt securities or placing us on a watch list for possible future downgrading would likely increase our cost of financing, limit our access to the capital markets and have an adverse effect on the market price of our securities, including our Senior Notes. We cannot be assured that our credit ratings will not be downgraded in the future.

Operation, Development, Exploration and Acquisition Risks

Mining accidents or other adverse events at an operation could decrease our anticipated production.

Production may be reduced below our historical or estimated levels as a result of mining accidents; unfavorable ground or shaft conditions; work stoppages or slow-downs; lower than expected ore grades; 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 or stope failure. Both the Lucky Friday and Casa Berardi mines have a history of ground instability and related incidents. 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.

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 upsets 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:

| • | environmental hazards;

| • | unusual or unexpected geologic formations;

| • | rock bursts, ground falls, or pit wall failures;

| • | seismic activity;

| • | underground fires or floods;

| • | unanticipated hydrologic conditions, including flooding and periodic interruptions due to inclement or hazardous weather conditions;

15

Table of Contents

| • | political and country risks;

| • | civil unrest or terrorism;

| • | industrial accidents;

| • | disruption, damage or failure of technology systems related to operation of equipment and other aspects of our mine operations;

| • | labor disputes or strikes; and

| • | our operating mines have tailing ponds which could fail or leak as a result of seismic activity, unusual weather or for other reasons.

Such risks could result in:

| • | personal injury or fatalities;

| • | damage to or destruction of mineral properties or producing facilities;

| • | environmental damage and financial penalties;

| • | delays in exploration, development or mining;

| • | monetary losses;

| • | asset impairment charges;

| • | legal liability; and

| • | temporary or permanent closure of facilities.

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 and political risk. There can be no assurance 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, too expensive for us, and we therefore do not maintain environmental insurance. Occurrence of events for which we are not insured may have an adverse effect on our business.

Our costs of 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:

| • | ore reserves;

16

Table of Contents

| • | expected ore grades and recovery rates of metals from the ore;

| • | future metals prices;

| • | facility and equipment costs;

| • | availability of adequate staffing;

| • | availability of affordable sources of power and adequacy of water supply;

| • | exploration and drilling success;

| • | capital and operating costs of a development project;

| • | environmental and closure, permitting and other regulatory considerations and costs;

| • | adequate access to the site, including competing land uses (such as agriculture);

| • | applicable tax rates;

| • | foreign currency fluctuation and inflation rates; and

| • | availability of financing.

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 ore reserve estimates may be imprecise.

Our ore reserve figures and costs are primarily estimates and are not guarantees that we will recover the indicated quantities of these metals. You are strongly cautioned not to place undue reliance on estimates of reserves (or mineralized material or other resource estimates). Reserves are estimates made by our professional technical personnel, and no assurance can be given that the estimated amount of metal or the indicated level of recovery of these metals will be realized. Reserve estimation is an interpretive process based upon available data and various assumptions. Our reserve estimates may change based on actual production experience. Further, reserves are valued based on estimates of costs and metals prices, which may not be consistent among our properties or across the industry. The economic value of ore reserves may be adversely affected by:

| • | declines in the market price of the various metals we mine;

| • | increased production or capital costs;

| • | reduction in the grade or tonnage of the deposit;

| • | increase in the dilution of the ore;

| • | future foreign currency rates, inflation rates and applicable tax rates;

| • | reduced metal recovery; and

| • | changes in environmental, permitting or other regulatory requirements.

Short-term operating factors relating to our ore 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:

| • | delays in new project development;

| • | net losses;

| • | reduced cash flow;

| • | reductions in reserves;

| • | write-downs of asset values; and

| • | mine closure.

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 and decrease the value of our stock.

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 ore reserves by locating and developing additional ore. Our ability to expand or replace ore 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 ore reserves as they are depleted, which would adversely affect our business and financial position in the future.

Our joint development and operating arrangements may not be successful.

We have entered into joint venture arrangements in order to share the risks and costs of developing and operating properties. In a typical joint venture arrangement, the partners own proportionate shares of the assets, are entitled to indemnification from each other and are only responsible for any future liabilities in proportion to their interest in the joint venture. If a party fails to perform its obligations under a joint venture agreement, we could incur liabilities and losses in excess of our pro-rata share of the joint venture. We make investments in exploration and development projects that may have to be written off in the event we do not proceed to a commercially viable mining operation. See Note 15 of Notes to Consolidated Financial Statements.

Our ability to market our metals production may be affected by disruptions or closures of smelters and/or refining facilities.

We sell our metallic concentrates to smelters and brokers. Our doré bars are sent to refiners for further processing before being sold to metal traders. If smelters or refiners are unavailable or unwilling to accept our products, or we are otherwise unable to sell our products to customers, our operations could be adversely affected. See Note 11 of Notes to Consolidated Financial Statements for more information on the distribution of our sales and our significant customers.

Our business depends on finding skilled miners and maintaining good relations with our employees.

We are dependent upon the ability and experience of our executive officers, managers, employees and other personnel, and there can be no assurance that we will be able to retain such employees. We compete with other companies both in and outside the mining industry in recruiting and retaining qualified employees 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. The loss of these persons or our inability to attract and retain additional highly skilled employees could have an adverse effect on our business and future operations.

We may experience labor disputes, work stoppages or other disruptions in production that could adversely affect our business and results of operations. The Lucky Friday mine is our only operation where some of our employees are subject to a collective bargaining agreement, and the most recent agreement expired on April 30, 2016. On February 19, 2017, the unionized employees voted against out contract offer. We expect further discussions with the union but it is possible that an agreement will not be reached, in which case we cannot predict what might happen next, including what actions we or the union might take in response to failing to reach an agreement. If we do not successfully negotiate a new collective bargaining agreement with our union workers, we may incur prolonged strikes and other work stoppages at our mining operations, which could adversely affect our financial condition and results of operations. Additionally, if we enter into a new labor agreement with any union that significantly increases our labor costs relative to our competitors, our ability to compete may be materially and adversely affected.

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 obtain and develop solutions to 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. 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 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.

Our foreign activities are subject to additional inherent risks.

We currently have foreign operations in Mexico and Canada, 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, legal and economic risks such as:

| • | the effects of local political, labor and economic developments and unrest;

| • | significant or abrupt changes in the applicable regulatory or legal climate;

| • | significant changes to regulations or laws or the interpretation or enforcement of them, including with respect to tax and profit sharing matters arising out of the use of outsourced labor and other services at our San Sebastian operation in Mexico;

| • | exchange controls and export restrictions;

19

Table of Contents

| • | expropriation or nationalization of assets with inadequate compensation;

| • | unfavorable currency fluctuations, particularly in the exchange rate between the U.S. dollar and the Canadian dollar and Mexican Peso;

| • | repatriation restrictions;

| • | invalidation and unavailability of governmental orders, permits or agreements;

| • | property ownership disputes;

| • | renegotiation or nullification of existing concessions, licenses, permits and contracts;

| • | criminal activity, corruption, demands for improper payments, expropriation, and uncertain legal enforcement and physical security;

| • | failure to maintain compliance with corruption and transparency statutes, including the U.S. Foreign Corrupt Practices Act;

| • | disadvantages of competing against companies from countries that are not subject to U.S. laws and regulations;

| • | fuel or other commodity shortages;

| • | illegal mining;

| • | laws or policies of foreign countries and the United States affecting trade, investment and taxation;

| • | opposition to our presence, operations, properties or plans by governmental or non-governmental organizations or civic groups;

| • | civil disturbances, war and terrorist actions; and

| • | seizures of assets.

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 Quebec, Canada expose us to additional political risks.

Our presence in Quebec, Canada, and more specifically our properties there, 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 that may be in areas with a First Nations presence. 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, there is no assurance that relationships with such groups will be positive. Accordingly, it is possible that our production, exploration or development activities on these properties could be interrupted or otherwise adversely affected in the future by political uncertainty, native land claims entitlements, expropriations of property, 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 and 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 conditions and results of operations.

Table of Contents

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

Mining, processing, development and exploration activities depend on adequate infrastructure. Reliable roads, bridges, power sources, internet access and water supply are important to our operations, and their availability and condition affect capital and operating costs. Unusual or infrequent weather phenomena, sabotage, other interference in the maintenance or provision of such infrastructure, or government intervention, could adversely affect our mining operations.

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, including in the following areas:

| • | attracting and retaining key executives, skilled labor, and other employees;

| • | for the services of other skilled personnel and contractors and their specialized equipment, components and supplies, such as drill rigs, necessary for exploration and development; and

| • | for rights to mine properties.

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

We are actively seeking to expand our mineral reserves 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 often unproductive.

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

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, 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 risks factors. Acquisitions of other mining companies or properties may also expose us to new geographic, political, operating, and geological risks.

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 will be 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 include, among other things:

| • | operating a larger organization;

| • | operating in multiple legal jurisdictions;

21

Table of Contents

| • | coordinating geographically and linguistically disparate organizations, systems and facilities;

| • | adapting to additional political, regulatory, legal and social requirements;

| • | integrating corporate, technological and administrative functions; and

| • | diverting management's attention from other business concerns.

The process of integrating our 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.

We may not realize all of the anticipated benefits from our acquisitions.

We may not realize all of the anticipated benefits from any acquisitions, 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 and fluctuations in market prices.

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 acquisitions 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 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.

Legal, Regulatory and Market Risks

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, and additional actions may be filed against us. We may be subject to future claims, including those relating to environmental damage, safety conditions at our mines, and other matters. The outcomes of these pending and potential claims are uncertain. We may not resolve these claims favorably. Depending on the outcome, these actions could have adverse financial effects or cause reputational harm to us. If any of these disputes result in a substantial monetary judgment against us, are settled on terms in excess of our current accruals, or otherwise impact our operations, 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 7 of Notes to Consolidated Financial Statements.

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 implemented 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. There can be no assurance 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 such standards and regulations could become such that we would not proceed with a particular development or operation. We are often required to post surety bonds or cash collateral to secure our reclamation obligations and 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.

Legal challenges could prevent the Rock Creek or Montanore projects from ever being developed.

The proposed development of our Rock Creek project has been challenged by several regional and national conservation groups at various times since the U.S. Forest Service ("USFS") issued its initial Record of Decision ("ROD") in 2003 approving Revett Mining Company’s plan of operation (Revett is now our wholly-owned subsidiary, named Hecla Montana, Inc.). Some of these challenges have alleged violations of a variety of federal and state laws and regulations pertaining to Revett’s permitting activities at Rock Creek, including the Endangered Species Act, the National Environmental Policy Act, the General Mining Law of 1872 ("1872 Mining Law"), the Federal Land Policy Management Act, the Wilderness Act, the National Forest Management Act, the Clean Water Act, the Clean Air Act, the Forest Service Organic Act of 1897, and the Administrative Procedure Act. Although Revett successfully addressed most of these challenges, Revett was directed by the Montana Federal District Court in May 2010 to produce a Supplemental Environmental Impact Statement (“SEIS”) to address National Environmental Policy Act procedural deficiencies that were identified by the court. We cannot predict how possible future challenges will be resolved. Possible new court challenges in the future to the final SEIS and ROD may delay the planned development at Rock Creek. If we are successful in completing the SEIS and defending any challenges to Rock Creek, we would still be required to comply with a number of requirements and conditions as development progresses, failing which could make us unable to continue with development activities.

A joint final Environmental Impact Statement on the Montanore project was issued in December 2015 by the USFS and Montana Department of Environmental Quality, and each agency issued a Record of Decision in February 2016 providing approval for development of the Montanore project. However, private conservation groups have taken and may in the future take actions to oppose or delay the Montanore project, and there are currently three pending lawsuits challenging environmental permits that have been granted. In addition, there are three lawsuits pending which involve potential defects in title or limiting our access to the properties comprising the Montanore project. A development or outcome from one of these or any other lawsuit could limit our ability to access, develop or operate the Montanore project.

Rock Creek and Montanore are significant assets obtained in the acquisitions of Revett and Mines Management in 2015 and 2016, respectively. However, even if Rock Creek and Montanore are permitted, there is no assurance that they will be successfully developed or operated, including, among other reasons, because financing necessary to develop the projects may be unavailable.

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

Our business is subject to extensive U.S. and foreign, federal, state 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.

23

Table of Contents

U.S. surface and underground mines like the Lucky Friday and Greens Creek mines are continuously inspected by the U.S. Mine Safety and Health Administration (“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 we have been accused of causing environmental damage, violating environmental laws, or violating environmental 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 environmental obligations may exceed the provisions we have made and 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.

There can be no assurance 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. Although we are not currently mining on federal land, we do explore, and future mining could occur, on federal land.

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 U.S. 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 addition, we must obtain regulatory permits and approvals to start, continue and expand operations.

New or revised environmental regulatory requirements are frequently proposed, many of which result in substantially increased costs for our business, which could be the case under the proposed financial assurance regulations discussed in 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.

24

Table of Contents

We are subject to the Clean Water Act, 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, respectively, which has resulted in declines in such permits or extensive delays in receiving them, as well as the imposition of penalties for permit violations. Recently the regulatory definition of “waters of the United States” that are protected by the Clean Water Act was expanded by the EPA, thereby imposing significant additional restrictions on waterway discharges and land uses. These changes could increase litigation involving water discharge permits, which may result in delays in, or in some instances preclude, the commencement or continuation of development or production operations. Enforcement actions by the EPA could also result. 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 7 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 the Resource Conservation and Recovery Act (“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 causes 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 federal Clean Water Act.

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 who 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.

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 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 or 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 Hecla Limited or Hecla Mining Company liable for the actions of their subsidiaries or predecessors.

25

Table of Contents

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.

We are required by U.S. federal and state laws and regulations to reclaim our mining properties. The specific requirements vary among jurisdictions. In some cases, we are required to provide financial assurances as security for reclamation costs, which may exceed our estimates for such costs. Conversely, our reclamation costs may exceed the financial assurances in place and those assurances may ultimately be unavailable to us.

The EPA and state agencies may also require financial assurance for investigation and remediation actions that are required under settlements of enforcement actions under CERCLA or equivalent state regulations. Currently there are no financial assurance requirements for active mining operations under CERCLA, but in January 2017, in response to a lawsuit filed previously by several environmental organizations, the EPA proposed rules for financial assurance regulations under CERCLA governing the hard rock mining industry, which includes us. The proposed rules are now subject to a public comment period lasting until March 13, 2017 (unless extended). It is uncertain how the new requirements, if adopted, will affect the amount and form of our existing and future financial assurance obligations or the extent to which they will supplement or replace state requirements. However, based on the current draft of the proposed rules, the new requirements may be financially material and adverse to us.

Our environmental obligations may exceed the provisions we have made.

We are subject to significant environmental obligations. At December 31, 2016, we had accrued $85.6 million as a provision for environmental obligations. There can be no assurance that we have accurately estimated these environmental obligations, and in the future our accrual could materially change. Our environmental obligations could have a material adverse impact on our cash flows, results of operations, or financial condition. For information on our potential environmental liabilities, see Note 4 and Note 7 of Notes to Consolidated Financial Statements.

We face risks relating to transporting our products, as well as transporting employees and materials at Greens Creek.

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 such 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.

26

Table of Contents

In addition, 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. Any disruption to these forms of marine transportation could adversely impact mine operations, and possible effects could include suspension of operations.

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 U.S. 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 Hecla 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.

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. The market price for our stock has been volatile, often based on:

| • | changes in metals prices, particularly silver and gold;

| • | our results of operations and financial condition as reflected in our public news releases or periodic filings with the SEC;

| • | fluctuating proven and probable reserves;

| • | factors unrelated to our financial performance or future prospects, such as global economic developments, market perceptions of the attractiveness of particular industries, or the reliability of metals markets;

| • | political and regulatory risk;

| • | the success of our exploration, pre-development, and capital programs;

| • | ability to meet production estimates;

| • | environmental, safety and legal risk;

| • | the extent and nature of analytical coverage concerning our business; and

| • | the trading volume and general market interest in our securities.

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.

Our Series B preferred stock has a liquidation preference of $50 per share or $7.9 million.

If we were liquidated, holders of our preferred stock would be entitled to receive approximately $7.9 million (plus any accrued and unpaid dividends) from any liquidation proceeds before holders of our common stock would be entitled to receive any proceeds, but after holders of all notes issued under the indenture governing our Senior Notes received any proceeds.

27

Table of Contents

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. There can be no assurance 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 $0.01 per share of common stock, in each case payable quarterly, when declared. See Note 9 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 2016, our board of directors has declared a common stock dividend under the policy described above (although in some cases only a minimum dividend was declared and none relating to the average realized price of silver due to the prices not meeting the policy threshold). 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 there can be no assurance that we will continue to declare and pay common stock dividends in the future. 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.

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.

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.

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.

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 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:

| • | the classification of our board of directors into three classes serving staggered three-year terms, which makes it more difficult to quickly replace board members;

| • | the ability of our board of directors to issue shares of preferred stock with rights as it deems appropriate without stockholder approval;

| • | a provision that special meetings of our board of directors may be called only by our chief executive officer or a majority of our board of directors;

| • | a provision that special meetings of stockholders may only be called pursuant to a resolution approved by a majority of our board of directors;

| • | a prohibition against action by written consent of our stockholders;

| • | a provision that our board members may only be removed for cause and by an affirmative vote of at least 80% of the outstanding voting stock;

| • | a provision that our stockholders comply with advance-notice provisions to bring director nominations or other matters before meetings of our stockholders;

| • | a prohibition against certain business combinations with an acquirer of 15% or more of our common stock for three years after such acquisition unless the stock acquisition or the business combination is approved by our board prior to the acquisition of the 15% interest, or after such acquisition our board and the holders of two-thirds of the other common stock approve the business combination; and

| • | a prohibition against our entering into certain business combinations with interested stockholders without the affirmative vote of the holders of at least 80% of the voting power of the then outstanding shares of voting stock.

If we cannot meet the New York Stock Exchange continued listing requirements, the NYSE may delist our common stock.

Our common stock is currently listed on the NYSE. In the future, if we are not be able to meet the continued listing requirements of the NYSE, which require, among other things, that the average closing price of our common stock be above $1.00 over 30 consecutive trading days, our common stock may be delisted. Our closing stock price on February 20, 2017 was $6.58.

If we are unable to satisfy the NYSE criteria for continued listing, our common stock would be subject to delisting. A delisting of our common stock could negatively impact us by, among other things, reducing the liquidity and market price of our common stock; reducing the number of investors willing to hold or acquire our common stock, which could negatively impact our ability to raise equity financing; decreasing the amount of news and analyst coverage of us; and limiting our ability to issue additional securities or obtain additional financing in the future. In addition, delisting from the NYSE might negatively impact our reputation and, as a consequence, our business.

OPERATING PROPERTIES

The Greens Creek Unit

Various of our subsidiaries collectively own 100% of the Greens Creek mine, located on Admiralty Island near Juneau in southeast Alaska. Admiralty Island is accessed by boat, float plane, or helicopter. On the island, the mine site and various surface facilities are accessed by 13 miles of all-weather gravel roads. The Greens Creek mine has been in production since 1989, with a temporary care and maintenance period from April 1993 through July 1996. Since the start of production, Greens Creek has been owned and operated through various joint venture arrangements. For approximately 15 years prior to April 16, 2008, our wholly-owned subsidiary, Hecla Alaska LLC, owned an undivided 29.7% joint venture interest in the assets of Greens Creek. On April 16, 2008, we completed the acquisition of all of the equity of two Rio Tinto subsidiaries holding a 70.3% interest in the Greens Creek mine, and which previously operated the mine, for approximately $758.5 million. The acquisition gave various of our subsidiaries control collectively of 100% of the Greens Creek mine.

The Greens Creek orebody contains silver, zinc, gold and lead, and lies within the Admiralty Island National Monument, an environmentally sensitive area. The Greens Creek property includes 440 unpatented lode mining claims, 58 unpatented millsite claims, 17 patented lode claims and one patented millsite. In addition, the Greens Creek site includes properties under lease from the U.S. Forest Service ("USFS") for a road right-of-way, mine portal and mill site access, camp site, mine waste area and tailings impoundment. 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 project consists of the mine, an ore concentrating mill, a tailings impoundment 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:

The Greens Creek deposit is a polymetallic, stratiform, massive sulfide deposit. The host rock consists of predominantly marine sedimentary, and mafic to ultramafic volcanic and plutonic rocks, which have been subjected to multiple periods of deformation. These deformational episodes have imposed intense tectonic fabrics on the rocks. Mineralization occurs most often along the contact between a structural hanging wall of quartz mica carbonate phyllites and a structural footwall of graphitic and calcareous argillite. Major sulfide minerals are pyrite, sphalerite, galena, and tetrahedrite/tennanite.

Pursuant to a 1996 land exchange agreement, the joint venture transferred private property equal to a value of $1.0 million to the U.S. Forest Service and received exploration and mining rights to approximately 7,500 acres of land with mining potential surrounding the existing mine. Any production from new ore discoveries on the exchanged lands will be subject to a federal royalty included in the land exchange agreement. The royalty is only due on any production from reserves that are not part of Greens Creek’s extralateral rights. Thus far, there has been no production triggering payment of the royalty. The royalty is 3% if the average value of the ore during a year is greater than the benchmark, and 0.75% if the value is equal to or less than the benchmark. The benchmark of $120 per ton is adjusted annually in July according to the Gross Domestic Product (GDP) Implicit Price Deflator until the year 2016, and at December 31, 2016, was at approximately $161 per ton when applying the latest GDP Implicit Price Deflator.

Greens Creek is an underground mine accessed by a ramp from surface which produces approximately 2,100 to 2,300 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 lead concentrate which contains most of the silver recovered; a zinc concentrate which is low in precious metals content; and a zinc-rich bulk concentrate that contains gold, silver, zinc, and lead and must be marketed to an imperial smelter. Doré is produced from the gravity concentrate by a third party processor and further refined and sold to precious metal traders and other concentrate products are sold to a number of smelters worldwide. See Note 11 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.

Table of Contents

In 2016, ore was processed at an average rate of approximately 2,229 tons per day and total mill recovery was approximately 78% for silver, 88% for zinc, 81% for lead and 68% for gold. The processing facility was originally constructed in 1988, with the first production commencing in 1989. Various modifications and upgrades have been made since that time. Changes to the flotation circuit have included: installation of regrind mills in 1992; mill recommissioning in 1996; expansion of concentrate cleaning equipment in 2000 and 2001; addition of a swing cell option in 2004, allowing for a reduction in bulk concentrate production; addition of an on-stream analyzer in 2006; expansion of lead rougher equipment in 2007; retrofit of 2 column sparge systems in 2010 and 2011; replacement of the carbon flotation columns complete with sparger upgrades in 2012 and 2013; installation of a replacement on-stream analyzer with an additional multiplexer in 2013 and 2014; and replacement of the sulfuric acid system with a carbon dioxide system for pH control in 2015. Significant changes to the grinding circuit since original construction have included a new motor, two stage screening, and various internal lining modifications for the SAG mill, and replacement of the primary cyclones and the addition of a trommel magnet in the ball mill.

Electricity for the Greens Creek unit is provided through the purchase of surplus hydroelectric power from Alaska Electric Light and Power Company (“AEL&P”), to the extent it is available after the power needs of Juneau and the surrounding area are met. When weather conditions are not favorable to maintain lake water levels sufficient for all of the power needs at Greens Creek to be met by available hydroelectric power, the mine relies on power provided by on-site diesel generators.

The employees at Greens Creek are employees of Hecla Greens Creek Mining Company, our wholly-owned subsidiary, and are not represented by a bargaining agent. There were 414 employees at the Greens Creek unit at December 31, 2016.

Definition drilling in 2016 focused on refining mineralized material at the Northwest West, 9A, and Deep 200 South zones. After applying economic analysis to these drilling results, and incorporating them into the life of mine plan, we expect this mineralized material to be converted into reserves. Other zones that were targeted by definition drilling included the East Ore and Upper Southwest zones. Underground exploration activities at Greens Creek in 2016 continued to define new mineralization along trend of the 9A, Deep 200 South and Southwest Bench zones. Additional exploration included drilling Gallagher Zone, Mine Syncline, and 5250 Zone targets.

In 2017, underground definition drilling is expected to begin on a multi-year project to refine known East Ore resources along the mineralized horizon. The Upper Plate, Deep 200 South, Gallagher, Deep Southwest, and West zones are expected to be advanced by definition drilling as well. Underground exploration in 2017 is expected to resume testing down plunge targets of the Deep 200 South, Gallagher, and Gallagher Fault Block zones after the advancement of the M390 exploration drift is complete. Surface drilling in 2017 is expected to concentrate on targets south of the 9A, 5250 and East Ore orebodies, and up-dip of the 5250 and Gallagher West zones.

As of December 31, 2016, we have recorded a $39.0 million asset retirement obligation for reclamation and closure costs. We maintained a $68.9 million reclamation and long-term water treatment bond for Greens Creek as of December 31, 2016. The net book value of the Greens Creek unit property and its associated plant, equipment and mineral interests was approximately $631.0 million as of December 31, 2016.

(1) | Includes by-product credits from gold, lead and zinc production. Cash Cost, After By-product Credits, Per Silver Ounce represents a measurement that is not in accordance with GAAP that management uses to monitor and evaluate the performance of our mining operations. We believe Cash Cost, After By-product Credits, Per Silver Ounce provides an indicator of economic performance and efficiency at each location and on a consolidated basis, as well as providing a meaningful basis to compare our results to those of other mining companies and other operating mining properties. A reconciliation of cost of sales and other direct production costs and depreciation, depletion and amortization, the most comparable GAAP measure, to this non-GAAP measure can be found in Item 7.

(2) | Proven and probable ore reserves are calculated and reviewed in-house and are subject to periodic audit by others, although audits are not performed on an annual basis. Cutoff grade assumptions vary by ore body and are developed based on reserve metals price assumptions, anticipated mill recoveries and smelter payables, and cash operating costs. Due to multiple ore metals, and complex combinations of ore types, metal ratios and metallurgical performances at Greens Creek, the cutoff grade is expressed in terms of net smelter return (“NSR”), rather than metal grade. The cutoff grade at Greens Creek is $190 per ton NSR. Our estimates of proven and probable reserves are based on the following metals prices:

|  | December 31, |
|  | 2016 |  |  | 2015 |  |  | 2014 |
Silver (per ounce) |  | $ | 14.50 |  |  | $ | 14.50 |  |  | $ | 17.25 |
Gold (per ounce) |  | $ | 1,200 |  |  | $ | 1,100 |  |  | $ | 1,225 |
Lead (per pound) |  | $ | 0.90 |  |  | $ | 0.90 |  |  | $ | 0.95 |
Zinc (per pound) |  | $ | 1.05 |  |  | $ | 0.90 |  |  | $ | 0.90 |

(3) | Reserves are in-place materials that incorporate estimates of the amount of waste that must be mined along with the ore and expected mining recovery. The 2016 reserve model assumes average total mill recoveries of 78% for silver, 68% for gold, 88% for zinc and 81% for lead.

(4) | The changes in reserves in 2016 versus 2015 are due to the addition of data from new drill holes, partially offset by continued depletion of the deposit through production. The changes in reserves in 2015 versus 2014 were due to continued depletion of the deposit through production and lower metals price assumptions, partially offset by the addition of data from new drill holes.

(5) | Probable reserves at the Greens Creek unit are based on average drill spacing of 50 to 100 feet. Proven reserves typically require that mining samples are partly the basis of the ore grade estimates used, while probable reserve grade estimates can be based entirely on drilling results. The proven reserves reported for Greens Creek for 2016 represent stockpiled ore.

(6) | Greens Creek ore reserve estimates were prepared by Robert Callaghan, Chief Geologist, and Kerry Lear, Senior Resource Geologist (contractor) at the Greens Creek unit and reviewed by Keith Blair, Senior Resource Geologist at Hecla Limited and Dean McDonald, Senior Vice President of Exploration.

The Lucky Friday Unit

Since 1958, we have owned and operated the Lucky Friday mine, a deep underground silver, lead and zinc mine located in the Coeur d’Alene Mining District in northern Idaho. Lucky Friday is one-quarter mile east of Mullan, Idaho, and is adjacent to U.S. Interstate 90. The mine site and various surface facilities are accessed by paved roads from U.S. Interstate 90. Below is a map illustrating the location and access to the Lucky Friday unit:

There have been two ore-bearing structures mined at the Lucky Friday unit. The first, mined through 2001, was the Lucky Friday Vein, a fissure vein typical of many in the Coeur d’Alene Mining District. The ore body is located in the Revett Formation, which is known to provide excellent host rocks for a number of ore bodies in the Coeur d’Alene Mining District. The Lucky Friday Vein strikes northeasterly and dips steeply to the south 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 body in and along the Lucky Friday Vein. The major part of the ore body has extended from 1,200 feet to 6,020 feet below surface.

The second ore-bearing structure, known as the Lucky Friday Expansion Area, or Gold Hunter, has been mined since 1997 pursuant to an operating agreement with Silver Hunter Mining Company (“Silver Hunter”), our wholly owned subsidiary. During 1991, we discovered several mineralized structures containing some high-grade silver ores in an area known as the Gold Hunter property, approximately 5,000 feet northwest of the then existing Lucky Friday workings. This discovery led to the development of the Gold Hunter property on the 4900 level. At approximately 4,900 feet below surface, the Gold Hunter Veins are hosted in a 200-foot thick siliceous lens within the Wallace Formation that transitions to the St. Regis Formation below 5,900 feet. The veins are sub-parallel, and are numbered consecutively from the hanging wall of the favorable horizon to the footwall. The strike of the vein system is west-northwest with a dip of 85 degrees to the south. The 30 Vein, which has been demonstrated to contain higher silver grades, represents approximately 70% of our current proven and probable ore reserve tonnages, while the remaining 30% of our reserves are contained in various intermediate veins having lower silver grades than 30 Vein. While the veins share many characteristics with the Lucky Friday Vein, the Gold Hunter area possesses some mineralogical and rock mechanics differences that make it more favorable to mine at this time. On November 6, 2008, we, through Silver Hunter, completed the acquisition of substantially all of the assets of Independence Lead Mines Company, which held an interest in the Gold Hunter property. The acquisition included all future interests or royalty obligations to Independence and the mining claims pertaining to the operating agreement with Hecla Limited that was assigned to Silver Hunter.

The principal mining method at the Lucky Friday unit is ramp access, cut and fill. This method utilizes rubber-tired equipment to access the veins through ramps developed outside of the ore body. Once a cut is taken along the strike of the vein, it is backfilled with cemented tailings and the next cut is accessed, either above or below, from the ramp system.

In 2016, production averaged 803 tons milled per day, and total mill recovery was approximately 95% for silver, 96% for lead, and 94% for zinc. Ore at the Lucky Friday is processed using a conventional lead/zinc flotation flowsheet, with process control guided by a real-time, on-line analyzer. Run of mine ore is crushed in a conventional three stage crushing plant consisting of a primary jaw crusher, and a secondary crushing circuit, and tertiary cone crushing stage. Crushed ore is ground in a ball mill, and the ground slurry reports to the lead flotation circuit. The lead circuit tailings report to the zinc flotation circuit. Lead and zinc concentrates are thickened and filtered, and final concentrate products are shipped to smelters for final processing. The original flotation mill was constructed in 1960 and had a capacity of 750 tons per day. Various modifications and upgrades have been made since that time, including: installation of a 1,000 ton course ore bin and replacement of the ball mill in 1984 to increase processing capacity to 1,000 tons per day; replacement of the double-deck crushing screen with a triple-deck screen, installation of a tertiary cone crushing stage, lead concentrate flash flotation equipment, four ball mill cyclones, a mill feed sampler, and lead concentrate column cleaners and thickeners in 2005; addition of dust collection equipment in the crushing plant in 2006; installation of zinc concentrate flash flotation, conditioning, and column cleaner equipment, and an on-stream analyzer in 2007; construction of two new water treatment plants in 2008, with ongoing enhancements to those facilities since that time; addition of a discharge event pond in 2009; sand cyclone and reagent equipment in 2011; and various refurbishments made during the temporary suspension period in 2012 discussed below. Current processing capacity of the Lucky Friday facility is approximately 1,000 tons per day. All lead and zinc concentrate production during 2016 was shipped to Teck Resources Limited's smelter in Trail, British Columbia, Canada.

During 2008, we initiated engineering, procurement and development activities relating to construction of #4 Shaft, which, upon completion, would provide access from the 4900 level down to the 8600 level. The project was temporarily placed on hold in the fourth quarter of 2008 due to then prevailing metals prices. However, detailed engineering, long lead time procurement, and other early-stage activities for the internal shaft project resumed in 2009. The #4 Shaft sinking activities were temporarily suspended until certain rehabilitation work in the Silver Shaft was completed in early 2013. The #4 Shaft project has been completed, with commissioning finalized in January 2017. Activities related to the project as of December 31, 2016 have included engineering, detailed shaft design, excavation of the hoist room and off shaft development access to shaft facilities, installation of the hoist and head works, placement and receipt of orders for major equipment purchases, advancement of a geotechnical drill hole, 3,690 feet of vertical excavation to its final depth, shaft furnishing, installation of permanent conveyances, and other construction activities. Completion of #4 Shaft and associated development should allow us to mine mineralized material below our current workings and provide deeper platforms for exploration.

During 2014, Lucky Friday continued implementation of an Environmental Management System and completed installation of remote stream gauging stations. These stations assist in performing daily monitoring activities in nearby receiving waters as required by our effluent discharge permit. Additionally, we have completed reclamation activities on the 26 acre Mine Tailing Impoundment Structure ("MTIS") 4 borrow site and achieved final stabilization of the site prior to onset of winter conditions. In 2015, closure plans and costs were updated and developed for MTIS 3 and 4. The closure cost for MTIS 3 is based on the closure design and cost estimate developed by a third-party firm in conjunction with cost estimates prepared by Lucky Friday personnel to complete necessary associated work to facilitate the closure of the impoundment. The closure cost for MTIS 4 is based on the most recent closure cap design and was prepared for us by a consultant. At December 31, 2016, an asset retirement obligation of approximately $9.2 million had been recorded for closure of MTIS 3 and 4, reclamation and closure of the mine and mill upon the end of the known mine life based on a revised plan developed in 2016, and ongoing monitoring and maintenance.

The net book value of the Lucky Friday unit property and its associated plant, equipment and mineral interests was approximately $431.3 million as of December 31, 2016. The age of the facilities at Lucky Friday ranges from the 1950s to 2016.

At December 31, 2016, there were 310 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 the Lucky Friday’s 240 hourly employees. As further discussed in Item 1A. Risk Factors, the current labor agreement expired on April 30, 2016.

Avista Corporation supplies electrical power to the Lucky Friday unit.

Exploration drilling resumed at Lucky Friday in the fourth quarter of 2016 after a suspension of such activity since 2013. This represented the first exploration effort since 2011. Four holes tested for a westerly continuation of 30 Vein mineralization beyond the modeled boundary of mineralized material. This boundary had been defined by a fault segment, in what is described as the Silver Fault Zone. Each hole intercepted mineralization beyond the bounding fault, but the vein interpretation will require additional infill definition drilling east of, and along the margin of the current boundary of mineralized material to better define the resource. This infill definition drilling program began in December of 2016 and is expected to continue into 2017.

Definition drilling in 2017 is expected to occur from the 6350-52 Ramp West, 6500 East Lateral, and 6500 Far East to test the 30 Vein and a portion of the 30 Vein offset by the Silver Fault. Drilling is also expected to refine the intermediate vein package at the 6500 level and upgrade 30 Vein resources on the eastern end of the deposit. These adjacent veins are roughly defined as intermediate veins which have become an increasingly significant component of the mine’s production mix within the life of mine plan.

Exploration may resume again late in 2017 on the far-east end of the Lucky Friday Extension deposit. The goal of this exploration drilling is to define vein extensions for the 30 Vein and intermediate veins.

(2) | Proven and probable ore reserves are calculated and reviewed in-house and are subject to periodic audit by others, although audits are not performed on an annual basis. Cutoff grade assumptions vary by ore body and are developed based on reserve metals price assumptions, anticipated mill recoveries and smelter payables, and cash operating costs. Due to multiple ore metals, and complex combinations of ore types, metal ratios and metallurgical performances at Lucky Friday, the cutoff grade is expressed in terms of net smelter return (“NSR”), rather than metal grade. The cutoff grade at Lucky Friday ranges from $161 per ton NSR to $171 per ton NSR. Our estimates of proven and probable reserves are based on the following metals prices:

The Casa Berardi Unit

In 2013, as a result of our acquisition of Aurizon Mines Ltd. ("Aurizon"), we acquired the Casa Berardi mine, located 95 kilometers north of La Sarre in the Abitibi Region of northwestern Quebec, Canada. The mining site is reached via a 38 kilometer all season gravel road which connects with the provincial and national paved roads grid. The property is limited to the west by the Quebec/Ontario border and covers parts of Casa Berardi, Dieppe, Raymond, D'Estrees, and Puiseaux townships. The project area extends east-west for more than 37 kilometers and reaches 3.5 kilometers in width. The Casa Berardi mine gold deposits are located along a 5 kilometer east-west mineralized corridor.

The Casa Berardi mine is located in the northern part of the Abitibi sub-province, a subdivision of the Superior province, within the Canadian Shield. The Casa Berardi area belongs to the Harricana-Turgeon Belt, which is a part of the North Volcanic Zone. The regional geology is characterized by a mixed assemblage of mafic volcanics, flysch-type sedimentary iron formations, and graphitic mudrocks that are limited by a large granodioritic to granitic batholith. Structurally, the area is enclosed in the Casa Berardi Tectonic Zone, a 15 kilometers wide corridor that can be traced over 200 kilometers. A network of east-west to east-southeast and west-northwest ductile high strain zones mainly follows the lithological contacts.

Casa Berardi can be classified as an Archean sedimentary-hosted orogenic gold deposit. Mineralization is found in large low-sulphide quartz veins developed against the Casa Berardi fault, and in disseminated sulfides and stockworks lenses associated with strongly carbonate-sericite altered ductile deformation zones obliquely oriented to the Casa Berardi fault, and extending a few hundred metres on both sides of the fault following northwest and northeast orientations. Gold mineralization emplacement was coeval with the fault`s evolution and shows a strong structural control and vertical extension, even if other factors such as the nature of some host rocks and lithological contacts seem to have favored gold deposition.

The Casa Berardi Fault is defined by a stratigraphic contact between a graphite-rich sediment sequence at the base of the Taïbi domain, a northern continuous intermediary fragmental volcanic unit, and a southern polymictic conglomerate unit. The mineralization system is composed of large, low-sulfide quartz veins and low-grade stockworks and carbonate-mica replacement zones forming in the West Mine and Principale area. On the north side of the Fault, a thick sequence of very homogeneous wacke belonging to the Taïbi Group is affected by an amphibolites metamorphic grade. One kilometer further north is the easterly elongated Recher batholith, which is part of the north-western boundary of the Abitibi greenstone belt.

Aurizon acquired the claims, leases and infrastructure comprising the Casa Berardi mine project in 1998 from TVX Gold Inc. Aurizon engaged in exploration programs beginning in 1998, and production began in late 2006.

The nearest commercial airport to the Casa Berardi mine is located at Rouyn-Noranda. La Sarre can be reached from Rouyn-Noranda via provincial roads 101 and 111. The 38 kilometer all-season gravel road to the mine site branches off from the paved Route des Conquérants road, which runs north from its intersection with road 393 north of La Sarre and passes through the village of Villebois. The branch is approximately 21 kilometers north of Villebois. A gravel road links the East Mine and the West Mine (which roughly represent the east-west boundaries of the mine), and a number of forestry roads provide access to the rest of the project area, from east and west.

Hecla Quebec Inc., Hecla’s wholly owned subsidiary, owns a 100% interest in the mineral titles and mining leases comprising the current Casa Berardi mine. The Casa Berardi mine is composed of 69 contiguous claims, covering 3,148.3 hectares (7,779.6 acres) and two mining leases covering 481.4 hectares (1,189.7 acres). The Casa Berardi property area totals 3,629.75 hectares (8,969.3 acres). All the claims and leases are in good standing. We own an additional approximately 29,000 acres of exploration property located adjacent to the current Casa Berardi mine and comprised of approximately 230 claims, most of which are subject to a 1% NSR royalty in favor of Lake Shore Gold Corp.

We also hold a non-exclusive lease BNE 25938 for a sand and gravel pit, tailings lease 70218, and an additional 12 acres of land contiguous to mining lease BM 768 for rock waste material storage.

Under the Quebec Mining Act, claims are required to be renewed every two years. Statutorily prescribed minimum work commitments apply to all claims and leases. As of December 31, 2016, the claims and leases comprising part of the Casa Berardi mine have excess work credits of CAD$47.5 million.

The project consists of an underground mine and the East Mine Crown Pillar open pit mine. The underground mine has two shafts; the West Mine shaft reaching a vertical depth of 1096 meters, and the unused East Mine shaft located 4.3 kilometers to the east, and going down to a vertical depth of 379 meters. A system of declines and drifts connecting both shafts provide access and underground services to ore zones. The surface infrastructures include a cyanidation processing mill (carbon-in-leach), tailings impoundment areas, and other facilities and infrastructures. Power supply to the site is provided by a 55 kilometer, 120kV power line from the Hydro-Québec transformation station located in the town of Normétal. The map below illustrates the location and access to Casa Berardi:

Prior to Aurizon’s ownership, the Casa Berardi underground mine operated from 1988 to 1997, producing approximately 3.9 million tons of ore at an average gold grade of 0.2 ounces per ton from two sites, the West Mine and the East Mine. Aurizon’s operations from 2006 to 2012 produced approximately 4.5 million tons of ore at an average gold grade of 0.3 ounces per ton. A total of 1,625,500 ounces of gold were recovered by the previous operators prior to 2013. The mineral deposits cover a distance of more than 5.0 kilometers.

The underground mine at Casa Berardi is a trackless mine accessed by declines and a shaft, which produces approximately 2,300 tons of ore per day. The mining methods are longhole transversal stoping in 10 metres or more mineralization width, and longitudinal retreat stoping in narrower ore bodies. The mineralized zones put in reserves are of varying thickness, ranging from a few tenths of meters to 3 metres, which is the minimum mining width. Most of the hanging walls are sub-vertical (55° to 85°), with typically the graphitic Casa Berardi fault at the footwall.

In 2014, we completed a project initiated by Aurizon to deepen the West Mine Shaft and construct the associated shaft infrastructure, including loading pockets, shaft lining, services and steel.

The gold recovery process is based on CIL (carbon in leach) technology where gold is dissolved in a cyanide solution, and precipitated on activated carbon grains put in suspension. The product is doré bars poured in the mill’s refinery. Construction of the processing facility, consisting of a crushing plant, a 2,400 tons per day ore processing plant and tailings facility, was completed in 1988 by Inco Gold and Golden Knight Resources Inc., and ore processing began in September 1989, and during the next 9 years the mill processed 3.9 million tons at an average grade of 0.2 ounces per ton. Production at Casa Berardi was suspended in 1997 and the mill was put on care and maintenance until 2005, when major rehabilitation work was initiated by Aurizon. Beginning in the third quarter of 2005, upgrades including refurbishing of the crushing, grinding circuits, conveyors, and leach circuits, the addition of gravity circuits, and construction of an assay laboratory were performed, resulting in an increase of mill capacity. The mill facility was commissioned in November of 2006 and the processing rate ramped up to reach commercial production in May of 2007. During 2016, modifications were made to the plant to increase capacity to accommodate ore production from the open pit mines. In 2016, total mill recovery of gold was approximately 88%.

Current reserves at the Casa Berardi mine comprise seven zones at the West Mine, spread over a moderate horizontal distance from each other and located at different mine elevations, plus open pit and underground areas at the East Mine. Zone 113, Lower Inter Zone, 118, 121,123, the Principal Zones (open pit and underground) and the East Mine (open pit and underground) comprise the bulk of the deposit tonnage. The zones are of varying thickness, ranging from over 50 meters to less than three meters, which is the minimum mining width. Most of the hanging walls are sub-vertical (55º to 85º) and exhibit similar wall characteristics with the exception of the Lower Inter Zone, which in a number of places has relatively shallow hanging wall configurations (less than 45º).

A transverse blasthole open stoping mining method was selected for the Casa Berardi mine to provide the desired production rate. Timely supply of both cemented and unconsolidated backfill plays a crucial role in controlling dilution and maintaining a short stoping cycle. We believe this mining method satisfies all of the geotechnical requirements and constraints and, as a non-entry mining method, has proven to be safe and reliable in similar operations.

A very small part of the mineral reserves is planned for longitudinal sequencing, limited to the fringes of the small zones. Longitudinal methods have the advantage of lower waste development requirements; however, there is much less flexibility in sequencing and in access, should ground instabilities occur.

The transverse mining method is used in areas with wide mineralization (10 meters wide or more) and good access from nearby development. The blasthole longitudinal mining method will be used in areas with narrow mineralization, or long distances from development infrastructure.

In early 2016, we made the decision to move forward with construction of the East Mine Crown Pillar ("EMCP") open pit, which is situated between the East Mine and West Mine. Stripping and development of the EMCP pit is planned to take place over five stages. The first stage was completed in the first half of 2016, and processing of ore from the EMCP pit began in July 2016. Stripping and development has been ongoing. The EMCP pit, as currently designed, is a smaller scale operation using conventional open pit mining methods, and is expected to run for approximately 5.5 years of production. The average amount of material to be moved every six months is anticipated to be approximately 160,000 to 260,000 tons of ore, with variable quantities of waste.

The Principale Zone open pit, as currently designed, would be mined using conventional open pit mining methods. The Principale Zone open pit is expected to commence production after the EMCP pit is depleted and to run for approximately 4 full years of production. The average amount of material to be moved every six months is expected to approximate 450,000 tons of ore, with variable quantities of waste.

The mine and mill complex are permitted to process 1,250,000 dry metric tonnes (approximately 1,378,000 tons) of ore per year at a rate of 3,775 tons per day. Difficult ground conditions and bottlenecks in stope preparation have limited underground production to levels below the designed capacity. In 2016, the mill processed approximately 997,579 tons, for an average of 2,726 tons per day. During the fourth quarter of 2016, the mill processed approximately 3,307 tons per day, with the increase due primarily to the addition of ore from the EMCP pit. The current life of mine plan is based on an average milling rate of approximately 3,500 tons per day, with the inclusion of material from the surface mines, for the remaining mine life.

Based on current ore reserve estimates, the known life of mine plan totals 13.6 million tons of ore grading 0.11 ounces of gold per ton, with production for approximately 11 years.

At Casa Berardi, in-stope drilling refines orebody shapes and gold grade distributions within the orebodies for mine planning. Underground definition drilling involves evaluating along strike or down plunge projections of the existing ore zones. Exploration drilling evaluates similar trends but beyond currently defined mineralization and also evaluates previously untested targets identified along major structural trends such as the Casa Berardi Fault and a number of other structures or zones that may be mineralized. During 2016, up to six drills operated underground and up to two drills operated on the surface to refine stope designs, upgrade and expand known mineralization to reserves and identify new mineralization in the 104, 113, 118, 123, 124, 134, Lower Inter and North Domain Zones.

Table of Contents

The proposed 2017 underground in-stope and definition drilling programs are expected to appraise the high grade ore shoots of the 113, 118, 123 Principale Zones and Lower Inter area. Surface definition drilling is also expected to occur at the 160 Zone to potentially reclassify the resources to reserves. Surface and underground exploration drilling in 2017 is expected to evaluate extensions of the 104, 118, 123, 124, 134, North Domain, South Domain, West Mine area, North West, and Lower Inter Zones. A surface program is also expected to evaluate new targets to the west, but along trend of the Casa Berardi Mine.

We expect the mine plan will continually be modified as new mineralization is discovered and upgraded to reserves.

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 559 employees at the Casa Berardi unit at December 31, 2016.

Hecla acquired Aurizon on June 1, 2013 for approximately CAD$740.8 million (US$714.5 million), and has operated the Casa Berardi mine since the acquisition. The net book value of the Casa Berardi unit property and its associated plant, equipment and mineral interests was approximately $764.5 million as of December 31, 2016. As of December 31, 2016, we have recorded a $5.5 million asset retirement obligation for reclamation and closure costs. We maintain a surety bond as financial guarantee for future reclamation and closure work.

The San Sebastian Unit

The San Sebastian mine is located approximately 60 miles northeast of the city of Durango, Mexico, on concessions acquired in 1999. Access to San Sebastian is via Mexico highway 40, approximately 6 miles east of Guadalupe Victoria, and then approximately 15 miles of paved rural road through the towns of Ignacio Allende and Emiliano Zapata.

Table of Contents

Our concession holdings cover approximately 160 square miles, including the Francine Vein, East Francine Vein, Middle Vein, North Vein, and the Andrea Vein and multiple outlying active exploration areas. Mineral concession titles are obtained and held under the laws of Mexico, and are valid for 50 years with the possibility of extending another 50 years. There are work assessment and tax requirements that are variable and increase with the time that the concession is held. The map below illustrates the location and access to San Sebastian:

Mineralization at the project occurs as low and intermediate sulfidation epithermal veins within the Saladillo valley area. Economically, the most important veins at the project are the Francine, East Francine, Middle and North veins located at the north end of the Saladillo valley and the Andrea Vein located 4 miles to the south. The veins are hosted within a series of shales with interbedded fine-grained sandstones interpreted to belong to the Cretaceous Caracol Formation. Most of the veins strike to the west-northwest and vein dips vary from steep toward the west to shallow toward the east. True vein widths range from 5 to 30 feet, and the average true width of the veins in the district is 8 feet.

Mineralization occurs in an epithermal setting at various paleo-depths. High-grade gold and silver occur both in the very shallow epithermal environment in the upper 1,000 feet of the crust as well as in deep silver-gold-lead-zinc root zones of the system at depths between 2,000 and 3,500 feet below the paleo-water table. Hypogene minerals include sphalerite, galena, argentite, pyrite, chalcopyrite, native silver and gold in electrum. The veins are oxidized down to approximately 300 feet below surface and the oxidized portions of the veins contain limonite, hematite, silver halides and various copper carbonates. Matrix minerals include fine-grained to coarsely crystalline quartz bands and chlorite-quartz-adularia bands and late calcite fill. Mineralization within the vein structures is generally deposited in high-grade “shoots” bound both laterally and horizontally by sharp gradients in grade-thickness.

Hecla operated the San Sebastian underground mine from 2001 to 2005. The historical life-of-mine production from the Francine and Don Sergio veins over four years was 11.2 million ounces of silver and 155,937 ounces of gold. Access to both underground workings was through ramps from the surface connecting one or more levels. Ore was mined by the cut-and-fill stoping method and extracted from the stopes using rubber-tired equipment and hauled to the surface in trucks.

Recent exploration success on the Middle, North, and East Francine veins and completion of a Preliminary Economic Assessment lead to the decision in the third quarter of 2015 to develop shallow open pit mines on those veins, with development commencing in the fourth quarter of 2015. Ore production from the Middle and East Francine veins commenced late in the fourth quarter of 2015, and from the North Vein in the first quarter of 2016. The pits are expected to extend to a maximum of approximately 270 feet in depth. Near-surface material is excavated, with drill and blast techniques used for deeper material. Ore production is anticipated to run for approximately 6 months at the East Francine and North veins and 16 months at the Middle Vein. Total production from the three pits is anticipated to range from 7,000 to 29,000 tons of ore per month over approximately 16 months, with variable quantities of waste, for total ore production of approximately 300,000 tons. Production is achieved through excavating and drilling and blasting the shallow-dipping, high-grade silver veins which carry significant gold credits.

In January 2017, work commenced to build a new underground decline and rehabilitate historical underground workings at the San Sebastian mine, in order to mine deeper ore from the Middle Vein. We expect underground production to commence by the end of 2017. Underground production is anticipated to total approximately 142,000 tons over 15 months. We expect to mine ore by the cut-and-fill stoping method and extracted from the stopes using rubber-tired equipment and hauled to the surface in trucks.

Run of mine ore is hauled in trucks by contractors to a processing facility near Velardeña, Durango, Mexico, which is located approximately 60 miles from the San Sebastian mine site. We previously owned the Velardeña mill, but now use it to process ore under a lease arrangement. Processing of ore from the open pits averaged approximately 391 tons per day in 2016, with recovery of approximately 94% silver and gold. As of December 31, 2016, we have the ability to extend the lease through 2018. The mill is a conventional leach, counter-current decantation and Merrill Crowe precipitation circuit capable of processing up to approximately 550 tons per day, depending on ore hardness. The ore is crushed in a two-staged crushing plant consisting of a primary jaw, a secondary cone crusher and a double-deck vibrating screen. The grinding circuit includes a primary ball mill and cyclone classifiers. The ground ore is thickened followed by agitated leaching and four stages of counter-current decantation to wash solubilized silver and gold from the pulp. The solution bearing silver and gold is clarified, deaerated and zinc dust added to precipitate silver and gold that is recovered in plate and frame filters. The precious metal precipitate is smelted and refined into doré, and is then shipped to a third-party refiner. Since construction of the mill in 1994, two leach tanks were added in 2001, a filter press was added in 2002, and the Merrill Crowe system and Autojet Filters were expanded and modified in 2012. In addition, rehabilitation of various components of the mill was completed in 2015 prior to the start of processing of the ore from the open pits.

At December 31, 2016, the net book value of the San Sebastian unit property and its associated plant and equipment was $6.7 million. Infrastructure includes a water supply system, maintenance shop, warehouse, laboratory, leased mill and related improvements, and various offices. Equipment and facilities are in good condition. December 31, 2016, $5.6 million has been accrued for reclamation and closure costs. All permits required for mining of the open pits and operation of the mill are in place.

There were a total of 52 employees at the San Sebastian unit as of December 31, 2016, with most of them employed by our subsidiary that provides certain specialized services to another subsidiary that owns the mine.. These employees are not represented by a bargaining agent. We currently primarily use third-party contractors for mining and operation of the processing facility. The hourly employees of the lessor of the processing facility are represented by the Sindicato Nacional de Trabajadores Mineros, Metalúrgicos, Siderúrgicos y Similares de la República Mexicana (a Mexico national union) as bargaining agent.

Electric power is purchased from Comisiòn Federal de Electricidad (a Mexico federal electric company).

Drilling success over the past three and a half years on the near-surface East Francine, Middle and North veins at the San Sebastian property has lead to open pit mine production on all three veins. The Francine, Andrea, Middle and North veins now define over 5.0 miles of mineralized strike length and are open along strike and at depth. The Francine Vein has currently been traced for over 7,000 feet along strike and to 600 feet of depth. The Middle Vein has been traced for nearly 9,000 feet along strike and to a depth of over 1,000 feet. Exploration and in-fill drilling of the western extension of the Middle Vein confirmed the continuity of the vein mineralization with design for exploitation from underground being finalized. The North Vein has a mineralized trend that extends over 4,000 feet along strike and 1,000 feet to depth and remains open along strike in both directions and at depth.

Exploration core drilling in 2017 is expected to initially concentrate on defining shallow high grade mineralization along northwest extensions of the North, Middle, and Francine veins and southeastern extension of the Francine and Middle veins,. Later in 2017, drilling is expected to also test for deeper, high grade mineralization within these same vein systems. Additional exploration drilling is expected to occur at the Esperanza Vein located approximately 1.5 miles west of the mine area. Other exploration activities in 2017 are expected to include reverse circulation ("RC") drilling to test gold and silver anomalies generated by previous rotary air blast drilling. These RC targets are primarily south of the mine site as well as along the La India and Zapata Norte veins located west of the mine site. As in previous years, these drill programs may be expanded with continued success.

(1) | Includes by-product credits from gold production. Cash Cost, After By-product Credits, Per Silver Ounce represents a measurement that is not in accordance with GAAP that management uses to monitor and evaluate the performance of our mining operations. We believe Cash Cost, After By-product Credits, Per Silver Ounce provides an indicator of economic performance and efficiency at each location and on a consolidated basis, as well as providing a meaningful basis to compare our results to those of other mining companies and other operating mining properties. A reconciliation of cost of sales and other direct production costs and depreciation, depletion and amortization, the most comparable GAAP measure, to this non-GAAP measure can be found in Item 7. — Management’s Discussion and Analysis of Financial Condition and Results of Operations, under Reconciliation of Cost of Sales and Other Direct Production Costs and Depreciation, Depletion and Amortization (GAAP) to Cash Cost, Before By-product Credits and Cash Cost, After By-product Credits (non-GAAP).

(2) | Proven and probable ore reserves are calculated and reviewed in-house and are subject to periodic audit by others, although audits are not performed on an annual basis. Cutoff grade assumptions vary by ore body and are developed based on reserve metals price assumptions, anticipated mill recoveries and refiner payables, and cash operating costs. Due to multiple ore metals, and complex combinations of ore types, metal ratios and metallurgical performances at San Sebastian, the cutoff grade is expressed in terms of net smelter return, rather than metal grade. The cutoff grade at San Sebastian is assumed to be $100 per ton NSR. The average prices used for the San Sebastian unit were:

|  | December 31, |
|  | 2016 |  |  | 2015 |
Silver (per ounce) |  | $ | 14.50 |  |  | $ | 14.50 |
Gold (per ounce) |  | $ | 1,200 |  |  | $ | 1,100 |

(3) | Reserves are in-place materials that incorporate estimates of the amount of waste that must be mined along with the ore. Metal recoveries vary by mine zone and ore grade. The 2016 reserve model assumes average total mill recoveries of approximately 94% for silver and gold.

(4) | The decrease in silver and gold reserves in 2016 compared to 2015 is the result of depletion of the deposit through production, including higher grade portions, partially offset by inclusion of definition drilling information.

(5) | San Sebastian ore reserve estimates were prepared by Keith Blair, Senior Resource Geologist at Hecla Limited, and reviewed by Dean McDonald, Senior Vice President of Exploration.

In September 2011 and February 2012, 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 $0.01 per share of common stock, in each case, payable quarterly, when declared. See Note 9 of Notes to Consolidated Financial Statements for more information on potential dividend amounts under the first component of the policy at various silver prices. The following table summarizes the quarterly common stock dividends declared by our board of directors for the years 2014, 2015 and 2016 and the first quarter of 2017:

Because the average realized silver price for each quarter of 2014, 2015 and 2016 was below the minimum threshold of $30 according to the policy, no silver-price-linked component was declared or paid. Prior to 2011, no dividends had been declared on our common stock since 1990. We cannot pay dividends on our common stock if we fail to pay dividends on our Series B preferred stock. 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 there can be no assurance that we will continue to declare and pay common stock dividends in the future.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

Established in 1891 in northern Idaho’s Silver Valley, we believe we are the oldest operating precious metals mining company in the United States and the largest silver producer in the U.S. Our corporate offices are in Coeur d’Alene, Idaho and Vancouver, British Columbia. Our production profile includes:

| • | silver, gold, lead, and zinc contained in concentrates shipped to various smelters or sold to brokers; and

| • | doré containing gold and silver, which is further refined before sale of the metals to precious metal traders.

Our operating properties comprise our four business segments for financial reporting purposes: the Greens Creek operating unit on Admiralty Island in Alaska, the Lucky Friday operating unit in Idaho, the Casa Berardi operating unit in Quebec, Canada, and the San Sebastian operating unit in Durango, Mexico. Since our operating mines are located in the U.S., Canada, and Mexico, we believe they have low or relatively moderate political risk, and less economic risk than mines located in other parts of the world. Our exploration interests are also in the United States, Canada, and Mexico, and are located in historically successful mining districts.

Our operating and strategic framework is based on expanding our production and locating and developing new resource potential. In 2016, we

| • | Reported sales of products of $646.0 million, which was a new record and 29% higher than our previous record in 2014 in spite of lower average prices for all metals we produce compared to that year.

| • | Achieved record silver production, which was 48% higher than our previous record in 2015, and gold production that was 24% higher compared to 2015. The higher silver production is due to having a full year of production at San Sebastian after commencing ore processing there in the fourth quarter of 2015, and improved ore grades and recoveries at Greens Creek and Lucky Friday. The increase in gold production is primarily the result of the addition of San Sebastian and higher throughput at Casa Berardi.

| • | Generated $225.3 million in net cash flows from operating activities, representing a 112% increase compared to 2015. See the Financial Liquidity and Capital Resources section below for further discussion.

| • | Realized excellent operating results at our San Sebastian unit after making the decision to develop a mine there in the third quarter of 2015 (discussed further below).

| • | Committed a significant level of capital expenditures (including lease additions, capitalized interest, and other non-cash items) of approximately $181.8 million, including $44.8 million at Lucky Friday, $42.0 million at Greens Creek, $67.6 million at Casa Berardi, and $6.0 million at San Sebastian.

| • | Substantially completed the #4 Shaft at Lucky Friday, the largest capital project in our history, which started in 2008.

| • | Commenced development of the EMCP open pit project at Casa Berardi, with processing of ore from EMCP beginning in July 2016.

| • | Maintained overall proven and probable reserves at December 31, 2016, with silver reserves remaining within 2% of its level in 2015, which was the highest in our history, and gold reserves remaining within 3% of its level in 2015. The slight decrease in reserves in 2016 was primarily due to depletion through production at San Sebastian. See Item 2. Property Descriptions for additional information on proven and probable reserves at each of our operating units.

| • | Performed exploration and pre-development activities during the year, drilling targets at our land packages in Alaska, Quebec, and Mexico.

| • | Acquired Mines Management, giving us ownership of the Montanore project in northwestern Montana as discussed below.

| • | Achieved the above milestones while maintaining a cash and short-term investments balance of $198.9 million as of December 31, 2016, an increase of $43.7 million during the year.

Silver, gold, lead, and zinc prices increased to annual averages of $17.10, $1,248, $0.85, and $0.95, respectively, for 2016, from average prices of $15.70 for silver, $1,160 for gold, $0.81 for lead, and $0.88 for zinc for 2015. However, average prices for all four metals were lower for 2016 compared to their annual averages for 2014, which were $19.08 for silver, $1,266 for gold, $0.95 for lead, and $0.98 for zinc. 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 and San Sebastian.

The factors driving metals prices are beyond our control and are difficult to predict. As noted above, prices have been highly volatile in the last three years and could be so in the future. Average prices in 2016 compared to those in 2015 and 2014 are illustrated in the Results of Operations section below. Additionally, the metal grades of ore mined are impacted by geology and mine planning efficiencies and operations, which has the potential to create constraints on production. Also, ore transportation and smelting schedules impact the timing of sales and final settlement.

See the Results of Operations section below for a discussion of the factors impacting income applicable to common stockholders for the three years ended December 31, 2016, 2015 and 2014.

Key Issues

We intend to achieve our long-term strategy of increasing production and expanding our proven and probable reserves through development and exploration, as well as by acquisitions. Our strategic plan requires that we manage several challenges and risks inherent in conducting mining, development, exploration and metal sales at multiple locations.

One such risk involves metals prices, over which we have no control except, on a limited basis, through the use of derivative contracts. As discussed in the Critical Accounting Estimates section below, metals prices are influenced by a number of factors beyond our control. Average market prices of silver, gold, zinc and lead in 2016 were lower than their levels in 2015, as illustrated by the table in Results of Operations below. While we believe 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.

On June 1, 2013, we completed the acquisition of all of the issued and outstanding common shares of Aurizon for total consideration of CAD$740.8 million (US$714.5 million). The acquisition gave us 100% ownership of the producing Casa Berardi gold mine, along with interests in various gold exploration properties in the Abitibi region of northwestern Quebec, Canada. As further discussed in Item 7A. Quantitative and Qualitative Disclosures About Market Risk, the acquisition has increased our exposure to risks associated with exchange fluctuations between the U.S. dollar and Canadian dollar. The acquisition was partially funded by $490 million in net proceeds from our issuance of Senior Notes in April 2013 (see Note 6 of Notes to Consolidated Financial Statements). As discussed in the Financial Liquidity and Capital Resources section below, we believe that we will be able to meet the obligations associated with the acquisition of Aurizon and the related debt; however, a number of factors could impact our ability to meet the debt obligations and fund our other projects.

Table of Contents

We make our strategic plans in the context of significant uncertainty about future availability of ore to mine and process. To sustain operations, we must find new opportunities that require many years and substantial expenditures from discovery to production. We approach this challenge by investing in exploration and capital in districts with known mineralization. On June 15, 2015, we completed the acquisition of Revett, giving us 100% ownership of the Rock Creek project, a significant undeveloped silver and copper deposit in northwestern Montana. In addition, on September 13, 2016, we completed the acquisition of Mines Management, giving us 100% ownership of the Montanore project, another significant undeveloped silver and copper deposit located approximately 10 miles from our Rock Creek project. See Note 15 of Notes to Consolidated Financial Statements for more information on these acquisitions. Development of Rock Creek and Montanore has been challenged by conservation groups at various times, and there can be no assurance that we will be able to obtain the permitting required to develop these projects. In Risk Factors, see Legal challenges could prevent the Rock Creek or Montanore projects from ever being developed for more information.

Volatility in global financial markets poses a significant challenge to our ability to access credit and equity markets, should we need to do so, and to predict sales prices for our products. We utilize forward contracts to manage exposure to declines in the prices of silver, gold, zinc and lead contained in our concentrates that have been shipped but have not yet settled, and zinc and lead contained in our forecasted future concentrate shipments. In addition, we have in place a $100 million revolving credit agreement under which there were no borrowings during 2016 or as of the filing date of this report.

During the third quarter of 2015, we made a development decision to mine near surface, high grade portions of silver and gold deposits at our San Sebastian project in Mexico. Ore production commenced in the fourth quarter of 2015 and has continued since that time. In addition, work began in the first quarter of 2017 to develop and rehabilitate underground access which would allow us to mine deeper portions of the deposits at San Sebastian. See the San Sebastian Segment section below for more information. We generated positive cash flows at San Sebastian in 2016, and we believe that we will continue to do so over the next approximately two years. However, our ability to generate positive cash flows at San Sebastian may be impacted by changes in estimated costs, precious metals prices, or other factors, and there can be no assurance that we will be able to develop and operate San Sebastian as anticipated.

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 attempt to implement reasonable best practices with respect to mine safety and emergency preparedness. We work with MSHA to address issues outlined in its investigations and inspections and continue to evaluate our safety practices.

As a result of industry-wide fatal accidents in recent years, primarily at underground coal mines, there has been an increase in mine regulation. In addition, under the Dodd-Frank Wall Street Reform and Consumer Protection Act, the SEC was directed to issue rules regarding the disclosure of mine safety data. Our ability to achieve and maintain compliance with MSHA 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 rules and regulations and the 1872 Mining Law.

Another challenge we face is the risk associated with environmental matters and ongoing reclamation activities. As described in Risk Factors and Note 7 of Notes to Consolidated Financial Statements, it is possible that our estimate of these liabilities (and our ability to estimate liabilities in general) may change in the future, affecting our strategic plans. We are involved in various environmental legal matters with no assurance that the estimate of our environmental liabilities or liquidity needs, or our strategic plans, will not 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 as favorable terms as possible.

Reserve estimation is a major risk inherent in mining. Our reserve estimates, which drive our mining and investment plans, the valuation of a significant portion of our long-term assets, and 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 must be considered as estimates. Our reserves are depleted as we mine. Reserves can also change as a result of changes in economic and operating assumptions.

Results of Operations

Sales of products by metal for the years ended December 31, 2016, 2015 and 2014 were as follows:

|  | Year Ended December 31, |

For the year ended December 31, 2016, we reported income applicable to common stockholders of $69.0 million compared to a loss of $87.5 million in 2015 and income of $17.3 million in 2014. The following factors led to those differences:

| • | Gross profit at our San Sebastian unit in 2016 of $82.7 million, with no profit or loss reported there in 2015 or 2014 as metal sales commenced there in the first quarter of 2016. In addition, gross profit at Greens Creek in 2016 of $69.1 million was higher than $32.6 million in 2015 and $45.5 million in 2014. At Casa Berardi, gross profit of $21.4 million in 2016 was higher than $4.9 million in 2015 and $17.8 million in 2014. In addition, gross profit at Lucky Friday of $18.3 million in 2016 was higher than gross profit of $1.1 million in 2015, but lower than gross profit of $21.9 million in 2014. See the Greens Creek Segment, Lucky Friday Segment, Casa Berardi Segment, and San Sebastian Segment sections below.

| • | Average realized silver, gold, lead and zinc prices in 2016 were higher compared to 2015, but were lower than in 2014. These price variances are illustrated in the table below.

|  |  | Average price for the year ended December 31, |
|  |  | 2016 |  |  | 2015 |  |  | 2014 |
Silver — | London PM Fix ($/ounce) |  | $ | 17.10 |  |  | $ | 15.70 |  |  | $ | 19.08 |
| Realized price per ounce |  |  | 17.16 |  |  |  | 15.57 |  |  |  | 18.46 |
Gold — | London PM Fix ($/ounce) |  |  | 1,248 |  |  |  | 1,160 |  |  |  | 1,266 |
| Realized price per ounce |  |  | 1,245 |  |  |  | 1,150 |  |  |  | 1,262 |
Lead — | LME Final Cash Buyer ($/pound) |  |  | 0.85 |  |  |  | 0.81 |  |  |  | 0.95 |

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 metal prices each period through final settlement. For 2016, we recorded net negative price adjustments to provisional settlements of $0.9 million compared to net positive price adjustments to provisional settlements of $0.6 million in 2015 and net negative adjustments of $2.3 million in 2014. The price adjustments related to silver, gold, zinc and lead contained in our concentrate sales were largely 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 concentrate and doré shipped during the period.

| • | Provision for closed operations and environmental matters decreased to $5.7 million in 2016 from $12.2 million in 2015 and $10.1 million in 2014. The 2015 provision includes a net $8.7 million charge for potentially resolving the exposure to liability at the South Dakota and Colorado Superfund Sites Related to CoCa Mines, Inc., which is in addition to $1.2 million in charges recognized in prior years. The 2014 provision includes a $5.6 million increase to the liability for the Johnny M site in New Mexico (See Note 7 of Notes to Consolidated Financial Statements for more information).

| • | Interest expense, net of amounts capitalized, of $21.8 million in 2016 compared to $25.4 million in 2015 and $26.8 million in 2014. The interest is primarily related to our Senior Notes issued in April 2013, with the net proceeds used to partially fund the acquisition of Aurizon, and additional issuances in 2014 to satisfy the funding requirements for one of our defined benefit pension plans (see Notes 6 and 16 of Notes to Consolidated Financial Statements).

| • | Exploration and pre-development expense decreased to $17.9 million in 2016 from $22.0 million in 2015 and $19.7 million in 2014. Our activity in 2016 included a continuation of extensive exploration work at our Greens Creek unit, on our land package near Durango, Mexico, and at the Casa Berardi mine and other projects on our land package in Quebec, Canada. "Pre-development expense" is defined as costs incurred in the exploration stage that may ultimately benefit production, such as underground ramp development, which are expensed due to the lack of proven and probable reserves. We advanced pre-development work at the San Sebastian property in Mexico during 2014 and 2015, resulting in the decision to develop a mine there in the third quarter of 2015.

| • | Reclassifications of $1.0 million, $3.0 million and $2.4 million in unrealized losses on certain marketable securities from other comprehensive income to current earnings in 2016, 2015 and 2014, respectively. The losses were recognized in current earnings in each period because the securities were deemed to be other than temporarily impaired.

| • | Costs related to the acquisition of Mines Management of $2.7 million in 2016 and the acquisition of Revett of $2.2 million in 2015.

| • | General and administrative costs, which increased to $45.0 million in 2016 from $34.2 million in 2015 and $31.5 million in 2014 primarily due to increased incentive compensation.

| • | Net mark-to-market gains on base metal forward contracts of $4.4 million in 2016, $8.3 million in 2015 and $9.1 million in 2014. These gains are related to financially-settled forward contracts on forecasted zinc and lead production as part of a risk management program, and resulted from decreases in zinc and lead prices during each period. We do not include silver and gold in this program.

57

Table of Contents

| • | Net foreign exchange loss of $2.9 million in 2016 compared to gains of $24.6 million in 2015 and $11.5 million in 2014. As discussed in Note 10 of Notes to Consolidated Financial Statements, in 2016 we initiated hedging programs to manage our exposure to fluctuations in the exchange rate between the U.S. dollar and Canadian dollar and Mexican peso and the impact on our future operating costs at our Casa Berardi and San Sebastian units.

| • | Income tax provision of $27.4 million in 2016 compared to an income tax provision of $56.3 million in 2015 and a benefit of $5.2 million in 2014. The provision in 2016 is primarily related to pre-tax net income, partially offset by a decrease in the valuation allowance for U.S. deferred tax assets. The provision in 2015 is primarily the result of an increase in the valuation allowance for U.S. deferred tax assets, partially offset by a decrease in the valuation allowance for Mexican deferred tax assets. The benefit in 2014, in spite of reporting income before income taxes of $12.6 million for the year, is the result of book-versus-tax differences for certain items in Canada and the U.S. See Corporate Matters and Note 5 of Notes to Consolidated Financial Statements for more information.

The $36.6 million increase in gross profit for 2016 compared to 2015 was primarily due to higher silver production as a result of higher ore grades, improved silver recoveries and higher silver prices. Higher gold, zinc and lead prices, partially offset by lower quantities sold for gold, zinc and lead, also impacted gross profit. The $23.7 million increase in gross profit for 2016 compared to 2014 was primarily the result of higher quantities sold for silver, gold and lead, partially offset by lower average prices for all four metals and less zinc sold. Average realized prices for silver, gold, zinc and lead for 2016 were higher than in 2015 by 9%, 8%, 9% and 2% respectively, and lower than in 2014 by 7%, 1%, 4% and 13% respectively.

Gross profit was also impacted by negative price adjustments to revenues of $0.8 million in 2016, positive price adjustments of $0.5 million in 2015 and negative price adjustments of $1.3 million in 2014. Price adjustments to revenues result from changes in metals prices between transfer of title of concentrates to buyers and final settlements during the period, and are partially offset by gains and losses on forward contracts related to concentrates that have been shipped.

Depreciation, depletion and amortization expense was 7% and 17% less in 2016 compared to 2015 and 2014, respectively, due primarily to the effect on units-of-production depreciation of an increase in the estimated life of mine.

The Greens Creek operation is partially powered by diesel generators, and production costs have historically been affected by fluctuations in fuel prices and hydroelectric power availability. Installed infrastructure allows hydroelectric power to be supplied to Greens Creek by Alaska Electric Light and Power (AEL&P) via a submarine cable from North Douglas Island, near Juneau, to Admiralty Island, where Greens Creek is located. This has reduced production costs at Greens Creek to the extent power has been available. During 2016, 2015 and 2014, Greens Creek received approximately 94%, 96% and 97%, respectively, of its electricity from hydroelectric power from AEL&P due to higher precipitation levels in southeastern Alaska. When weather conditions are not favorable to maintain lake water levels, the mine relies on diesel generated power. Fuel costs were approximately $3.3 million (3% of total production costs) at Greens Creek in 2016 compared to $4.7 million (4% of production costs) in 2015 and $5.5 million (5% of production costs) in 2014. The cost of hydroelectric power was $8.4 million (7% of production costs) in 2016, $7.3 million (6% of production costs) in 2015, and $7.2 million (6% of production costs) in 2014. The increase in cost of hydroelectric power is the result of a price increase per kwh purchased from $0.10 to $0.16 in September 2016.

Mining costs per ton decreased in 2016 by 3% compared to 2015 and were relatively unchanged compared to 2014. The lower mining costs were primarily the result of lower maintenance, labor and fuel costs. Milling costs per ton increased 5% compared to both 2015 and 2014 due to higher power costs, along with an increase in costs for labor, maintenance and reagents.

The chart below illustrates the factors contributing to the variances in Cash Cost, After By-product Credits, Per Silver Ounce for 2016 compared to 2015 and 2014:

Cash Costs, After By-product Credits, per Silver Ounce were lower in 2016 compared to 2015 due to lower mining, milling, treatment and other costs on a per-ounce basis and higher silver production, partially offset by lower by-product credits by $5.69 per ounce. The increase in Cash Costs, After By-product Credits, per Silver Ounce in 2016 compared to 2014 was the result of lower by-product credits by $8.93 per ounce, partially offset by lower mining, milling, treatment, and other costs on a per-ounce basis.

Mining costs decreased in 2016 compared to 2015 and 2014 due primarily to higher silver production resulting from improved silver recoveries and grades, as well as lower production costs year over year. Milling costs decreased in 2016 compared to 2015 and 2014 on a per-ounce basis, despite increasing on a per-ton basis as discussed above, due primarily to higher silver production.

Other costs for 2016 were lower compared to 2015 due to the effect of higher silver production, partially offset by higher mine license tax. Other costs for 2016 compared to 2014 were lower due to the effect of higher silver production and lower mine license tax.

Treatment costs were lower in 2016 compared to 2015 and 2014 as a result of higher silver production and improved payment terms from smelters. Treatment costs were also impacted by silver prices, as treatment costs include the value of silver not payable to us through the smelting process. The silver not payable to us is either recovered by the smelters through further processing or ultimately not recovered and included in the smelters' waste material. Treatment costs also include a price adjustment component that fluctuates with changes in base metal prices.

By-product credits per ounce were lower in 2016 compared to 2015 due to lower gold, zinc and lead production and higher silver production, partially offset by higher prices for silver, gold, zinc and lead. By-product credits per ounce were lower in 2016 compared to 2014 due to lower gold and zinc production and higher silver production, as well as lower prices for all four metals.

The difference between what we report as "production" and "payable metal quantities sold" is attributable to the difference between the quantities of metals contained in the concentrate we produce versus the portion of those metals actually paid for by our customers according to the terms of our sales contracts. 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. The differences in payable quantities sold for 2016 compared to 2015 and 2014 were due mainly to timing of concentrate shipments.

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

| • | silver has historically accounted for a higher proportion of revenue than any other metal and is expected to do so in the future;

| • | we have historically presented Greens Creek as a producer primarily of silver, based on the original analysis that justified putting the project into production, and believe that consistency in disclosure is important to our investors regardless of the relationships of metals prices and production from year to year;

| • | metallurgical treatment maximizes silver recovery;

| • | the Greens Creek deposit is a massive sulfide deposit containing an unusually high proportion of silver; and

| • | in most of its working areas, Greens Creek utilizes selective mining methods in which silver is the metal targeted for highest recovery.

Likewise, we believe the identification of gold, lead and zinc as by-product credits 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. In addition, we do not receive 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 we consider zinc, lead and gold to be by-products of our silver production, the values of these metals offset operating costs within our calculations of Cash Cost, After By-product Credits, per Silver Ounce.

In early 2014 we were engaged in negotiations with the U.S. Forest Service and state agencies on their proposed revisions to our previously-submitted reclamation and closure plan. In 2014, we updated our asset retirement obligation ("ARO") at Greens Creek to reflect a revised reclamation and closure plan having estimated undiscounted costs of approximately $96.7 million, an increase from the $73.9 million in the previous plan, which was primarily the result of a new requirement to include perpetual water treatment in the closure plan. This resulted in an increase to the ARO asset and liability of $2.2 million after discounting the estimated costs to present value. As part of the revised closure plan, we increased our reclamation bonding from $30 million to approximately $68.9 million in 2014. In the fourth quarter of 2016, we revised our ARO to reflect estimated undiscounted costs of approximately $100.1 million and expected timing of expenditures. This resulted in a decrease to the ARO asset and liability of $5.0 million due to the impact of discounting and the change in expected timing of expenditures.

The increase in gross profit for 2016 compared to 2015 was due to higher silver, lead, and zinc production due to higher ore grades, and higher average prices for all three metals. The lower grades in 2015 were a result of failure of the underground booster fan, which reduced the ventilation capacity of the mine, leading to the temporary closure of a higher-grade production stope. Production during most of the third quarter of 2015 came from lower grade material until the fan was replaced and other ventilation infrastructure completed. The decrease in gross profit in 2016 compared to 2014 was due primarily to reduced ore throughput and lower metals prices.

Gross profit was also impacted by depreciation expense, which increased in 2016 by 5% and 25% compared to 2015 and 2014, respectively, due to an increase in assets in service.

Mining costs per ton increased in 2016 by 9% and 12% compared to 2015 and 2014, respectively, and milling costs per ton in 2016 were 12% higher compared to both 2015 and 2014. The increase in per-ton costs was primarily the result of lower ore production and higher labor costs.

The chart below illustrates the factors contributing to the variances in Cash Cost, After By-product Credits, Per Silver Ounce for 2016, 2015 and 2014:

The decrease in Cash Cost, After By-product Credits, per Silver Ounce for 2016 compared to 2015 and 2014 was due to increased silver production as a result of higher grades. The variance compared to 2015 was also a result of higher by-product credits in 2016.

Mining and milling costs per ounce decreased slightly in 2016 compared to 2015 and 2014 as a result of higher silver production.

By-product credits increased in 2016 compared to 2015 due to higher lead and zinc production, as a result of improved grades, and higher average prices for those metals. However, by-product credits were lower in 2016 compared to 2014 due to lower lead and zinc prices.

Similar to the Greens Creek segment, the difference between what we report as “production” and “payable metal quantities sold” is due essentially to the difference between the quantities of metals contained in the concentrates we produce versus the portion of those metals actually paid for by our customers according to the terms of our sales contracts. Differences can also arise from inventory changes incidental to the timing of concentrate shipments, or variances in ore grades which impact the amount of metals contained in concentrates produced and sold.

While value from lead and zinc is significant, we believe that identification of silver as the primary product of the Lucky Friday unit is appropriate because:

| • | silver has historically accounted for a higher proportion of revenue than any other metal and is expected to do so in the future;

63

Table of Contents

| • | this mining district is long associated with silver production; and

| • | selective mining methods target silver production.

Likewise, we believe the identification of lead and zinc as by-product credits is appropriate because of their low economic value compared to silver and due to the fact that silver is the primary product we intend to produce. In addition, we do not receive 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 we consider zinc and lead to be by-products of our silver production, the values of these metals offset operating costs within our calculations of Cash Cost, After By-product Credits, per Silver Ounce.

The #4 Shaft project, an internal shaft at the Lucky Friday mine, is expected to provide deeper access which should in turn extend the mine's operational life and expand silver production. We commenced engineering and construction activities on the #4 Shaft in late 2008, and our Board of Directors gave its final approval of the project in August 2011. The #4 Shaft project, including excavation of the shaft to its final depth at 9,600 feet below surface, was completed in January 2017. Development to access ore from #4 Shaft is expected to continue through 2017.

Many of the employees at our Lucky Friday unit are represented by a union. The most recent collective bargaining agreement with the union expired on April 30, 2016, and on February 19, 2017, the unionized employees voted against our contract offer. We expect further discussions with the union but it is possible that an agreement will not be reached, in which case we cannot predict what might happen next, including what actions we or the union might take in response to failing to reach an agreement.

See Note 7 of Notes to Consolidated Financial Statements for more information about contingencies related to various accidents and other events that occurred at the Lucky Friday mine in prior periods.

Gross profit increased in 2016 compared to 2015 and 2014 primarily due to higher gold production as a result of increased mill throughput. Average gold prices were higher in 2016 compared to 2015, but were lower compared to 2014.

Gross profit for each year was also affected by depreciation expense, which increased in 2016 by 8% and 24% compared to 2015 and 2014, respectively, due to an increase in assets placed in service and the impact of higher throughput on units-of-production depreciation.

Mining costs per ton for 2016 were 6% lower than in 2015 and 14% lower than in 2014. The decrease is primarily due to higher ore production and foreign exchange differences between the periods, as the U.S. dollar strengthened relative to the Canadian dollar in 2016 and 2015, partially offset by stripping costs incurred for the EMCP pit starting in the third quarter of 2016 as discussed below. Foreign exchange differences impacted mining costs per ton in 2016 by approximately 3% compared to 2015 and 17% compared to 2014.

Milling costs per ton decreased by 4% in 2016 compared to 2015 and by 10% compared to 2014 mainly due to higher ore production and exchange rate differences.

In 2015, we made the decision to develop the EMCP project, a new open pit mine at Casa Berardi. Processing of ore from the EMCP pit began in July 2016, and approximately 8,500 gold ounces were produced from the pit in 2016. Costs for stripping of the EMCP pit were capitalized prior to the start of ore production, and have been expensed since that time. The EMCP pit is expected to contribute between 20,000 and 30,000 ounces of gold production for each of the approximately five years remaining on the project.

The chart below illustrates the factors contributing to Cash Cost, After By-product Credits, Per Gold Ounce for 2016, 2015 and 2014:

The decrease in Cash Cost, After By-product Credits, per Gold Ounce for 2016 compared to 2015 and 2014 was primarily the result of higher gold production and the continued strengthening of the U.S. dollar relative to the Canadian dollar, partially offset by the addition of EMCP pit stripping costs starting in the third quarter of 2016. Higher gold production impacted costs by approximately $96 per ounce and $100 per ounce in 2016 compared to 2015 and 2014, respectively. Foreign exchange differences impacted costs by approximately $26 per ounce and $137 per ounce in 2016 compared to 2015 and 2014, respectively.

The difference between what we report as "production" and "payable metal quantities sold" is mainly attributable to inventory changes incidental to the timing of sales of refined metals and shipping schedules.

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 there. In addition, we do not receive sufficient revenue from silver at 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.

The San Sebastian Segment

In the third quarter of 2015, we made the development decision to mine near surface, high grade portions of silver and gold deposits from shallow open pits at our San Sebastian unit in Mexico. We previously produced silver and gold from underground mines at San Sebastian from 2001 to 2005. A Preliminary Economic Assessment was completed, and development of the pits and mine production commenced in the fourth quarter of 2015. Mill production started in December 2015 with the ore processed at a leased mill. The first sales did not occur until early 2016 and included production from December 2015.

The ore processed in 2016 had considerably higher average grades than anticipated over the remaining mine life, which is currently expected to be approximately 24 months.

In January 2017, we started development of a new underground portal and work to rehabilitate historic underground infrastructure which, when completed, would allow us to mine deeper portions of the deposits at San Sebastian. We expect underground ore production to begin by the end of 2017.

The chart below illustrates the factors contributing to Cash Cost, After By-product Credits, Per Silver Ounce for the year ended December 31, 2016 and the 22 day period ended December 31, 2015:

The difference between what we report as "production" and "payable metal quantities sold" is mainly attributable to inventory changes incidental to the timing of sales of refined metals and shipping schedules.

We believe the identification of gold as a by-product credit is appropriate at San Sebastian because of its anticipated lower economic value compared to silver over the life of the mine. In addition, we will not receive sufficient revenue from gold at San Sebastian 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 we consider gold to be a by-product of our silver production at San Sebastian, the value of gold offsets operating costs within our calculations of Cash Cost, After By-product Credits, per Silver Ounce. In addition to the impact of the by-product credits from gold, because the orebody at San Sebastian is near surface and has higher precious metal grades, it has lower Cash Cost, Before By-product Credits, per Silver Ounce than our other silver mines, which also contributes to lower Cash Cost, After By-product Credits, per Silver Ounce.

Corporate Matters

Employee Benefit Plans

Our defined benefit pension plans, while affording a significant benefit to our employees, also represent a significant liability. During 2016, the funded status of our plans changed from a liability of $46.9 million at the first of the year to a liability of $44.9 million at the end of the year. The decreased liability was attributable to returns on plan assets and our contributions that, collectively, exceeded service costs, interest costs, and amortization of actuarial losses. We contributed approximately $2.6 million in shares of our common stock and cash to our defined benefit plans in February 2016, and $6.1 million in shares of our common stock in July 2016, with no additional contributions made in 2016. We expect to contribute a total of $4.0 million in shares of our common stock and cash to our defined benefit plans in 2017. See Note 8 of Notes to Consolidated Financial Statements for more information. While the economic variables which will determine future cash requirements are uncertain, we expect contributions to increase in future years under current plan provisions, and we periodically examine the plans for affordability and competitiveness.

Income Taxes

Each reporting period we assess our deferred tax assets utilizing long-range forecasts to provide reasonable assurance that they will be realized through future earnings. We continue to have a net deferred tax asset in the U.S. and a net deferred tax liability in Canada. Our net deferred tax asset in Mexico was fully utilized in 2016.

Our U.S. net deferred tax asset at December 31, 2016 totaled $35.8 million, or 2% of total assets, a decrease of $7.1 million from the $42.9 million net deferred tax asset at December 31, 2015. The largest component of the deferred tax asset is net operating loss carryforwards. The next largest component is deferred foreign exchange losses. In 2015, we determined that we are indefinite Alternative Minimum taxpayers, resulting in additional valuation allowance primarily related to forecasted utilization of regular net operating loss carryforwards and the effect of reducing the carrying value of the net temporary deferred tax assets measured at 35% to a net realizable tax rate of 20%. During the fourth quarter of 2016, we determined that we are eligible to take a different income tax position relating to the timing of deductions for #4 Shaft development costs at Lucky Friday. We filed with the Internal Revenue Service ("IRS") a request for approval to use this method and we believe the request will be approved during 2017, but we cannot be assured that it will. The change would result in additional deductions of approximately $188 million and $95 million for regular tax and AMT, respectively. We would reflect the effect of these changes to taxes payable and deferred taxes during the period in which the request is approved. At December 31, 2016, we retained a valuation allowance on U.S. deferred tax assets of $96.1 million, primarily for net operating loss carryforwards.

Our net Canadian deferred tax liability at December 31, 2016 was $122.9 million, an increase of $2.6 million from the $120.3 million net deferred tax liability at December 31, 2015. The deferred tax liability is the result of the acquisition of Aurizon completed on June 1, 2013 and is primarily related to the excess of the fair market value of the assets acquired over the tax bases of those assets for Canadian tax reporting, with the majority of that value allocated to mineral resources and reserves.

Our net Mexican deferred tax asset at December 31, 2016 was zero, a decrease of $11.7 million from the balance at December 31, 2015. The decrease resulted from San Sebastian having sufficient income in 2016 to utilize its net operating loss carryforwards. During the fourth quarter of 2016, we filed with the IRS a request for approval to change our tax treatment of exploration expenditures incurred in Mexico for purposes of calculating earnings and profits. We believe the request will be approved during 2017, but we cannot be assured that it will. The change would increase the cumulative earnings and profits balance by approximately $55 million. We would reflect the effect of this change, if any, during the period in which the request is approved. A $3.5 million valuation allowance remains on deferred tax assets in foreign jurisdictions.

As discussed in Note 5 of Notes to Consolidated Financial Statements, our effective tax rate for 2016 was 28% compared to negative 184% for 2015. The change in effective tax rate for 2016 was primarily the result of the change in the valuation allowances described above, the U.S. deduction for percentage depletion, and the impact of taxation in foreign jurisdictions, the impacts of which were amplified in 2015 by relatively low worldwide pre-tax book income. 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, and fluctuation in foreign currency exchange rates. As a result, the 2017 effective tax rate could vary significantly from that of 2016.

For the years 2016, 2015 and 2014, we had no unremitted foreign earnings. See Note 5 of Notes to Consolidated Financial Statements for more information.

Reconciliation of Cost of Sales and Other Direct Production Costs and Depreciation, Depletion and Amortization (GAAP) to Cash Cost, Before By-product Credits and Cash Cost, After By-product Credits (non-GAAP)

The tables below present reconciliations between the GAAP measure of cost of sales and other direct production costs and depreciation, depletion and amortization and the non-GAAP measures of Cash Cost, Before By-product Credits and Cash Cost, After By-product Credits at the Greens Creek, Lucky Friday, San Sebastian, and Casa Berardi units for the years ended December 31, 2016, 2015 and 2014. With commercial production beginning in late 2015, the San Sebastian unit's information is not applicable for 2014.

Cash Cost, After By-product Credits is an important operating statistic that we utilize to measure each mine's operating performance. It also allows us to benchmark the performance of each of our mines versus those of our competitors. As a primary silver mining company, we also use the statistic on an aggregate basis - aggregating the Greens Creek, Lucky Friday and San Sebastian mines, but not Casa Berardi, which is a primary gold mine - to compare our performance with that of other primary silver mining companies. Similarly, the statistic is useful in identifying acquisition and investment opportunities as it provides a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics.

Cash Cost, Before By-product Credits includes 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. By-product credits include revenues earned from all metals other than the primary metal produced at each unit. Cash Cost, After By-product Credits, per Ounce, provides management and investors an indication of operating cash flow, after consideration of the average price received from production. Management also uses this measurement for the comparative monitoring of performance of our mining operations period-to-period from a cash flow perspective. Cash Cost, After By-product Credits, per Ounce is a measure developed by precious metals companies (including the Silver Institute) in an effort to provide a uniform standard for comparison purposes. There can be no assurance, however, that our reporting of this non-GAAP measure is the same as that reported by other mining companies.

The Casa Berardi section below reports Cash Cost, After By-product Credits, per Gold Ounce for the production of gold, its 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. Thus, the gold produced at our Casa Berardi unit is not included as a by-product credit when calculating Cash Cost, After By-product Credits, per Silver Ounce for the total of Greens Creek, Lucky Friday and San Sebastian, our combined silver properties.

As depicted in the Greens Creek Unit, the Lucky Friday Unit, and the San Sebastian Unit 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.

Reconciliation of Net Income (Loss) (GAAP) to Earnings Before Interest, Taxes, Depreciation, and Amortization (non-GAAP)

The non-GAAP measure of earnings before interest, taxes, depreciation, and amortization ("EBITDA") is calculated as net income (loss) before the following items: interest expense, income tax provision (benefit), and depreciation, depletion, and amortization expense. Management believes that, when presented in conjunction with comparable GAAP measures, EBITDA is useful to investors in evaluating our operating performance. The table below presents reconciliations between the non-GAAP measure EBITDA to the GAAP measure of net income (loss) for the years ended December 31, 2016, 2015, 2014, 2013, and 2012 (in thousands).

| (1) | On April 12, 2013, we completed an offering of $500 million in aggregate principal amount of our Senior Notes due May 1, 2021, and issued additional Senior Notes in 2014 to fund one of our defined benefit pension plans. See Note 6 of Notes to Consolidated Financial Statements for more information. The Senior Notes bear interest at a rate of 6.875% per year from the date of original issuance or from the most recent payment date to which interest has been paid or provided for. Interest on the Senior Notes is payable on May 1 and November 1 of each year, commencing November 1, 2013.

Financial Liquidity and Capital Resources

Our liquid assets include (in millions):

|  | December 31, 2016 |  |  | December 31, 2015 |  |  | December 31, 2014 |
Cash and cash equivalents held in U.S. dollars |  | $ | 156.1 |  |  | $ | 137.0 |  |  | $ | 180.9 |
Cash and cash equivalents held in foreign currency |  |  | 13.7 |  |  |  | 18.2 |  |  |  | 28.8 |
Total cash and cash equivalents |  |  | 169.8 |  |  |  | 155.2 |  |  |  | 209.7 |
Marketable debt securities, current |  |  | 29.1 |  |  |  | — |  |  |  | — |
Marketable equity securities, non-current |  |  | 5.0 |  |  |  | 1.5 |  |  |  | 4.9 |
Total cash, cash equivalents and investments |  | $ | 203.9 |  |  | $ | 156.7 |  |  | $ | 214.6 |

Cash and cash equivalents increased in 2016, as discussed below. Cash held in foreign currencies represents balances in Canadian dollars and Mexican pesos, with the $4.2 million decrease in 2016 resulting primarily from a reduction in Canadian dollars held. Current marketable debt securities increased by $29.1 million (discussed below), and the value of non-current marketable equity securities increased by $3.5 million (discussed in Note 2 of Notes to Consolidated Financial Statements).

As discussed in Note 6 of Notes to Consolidated Financial Statements, on April 12, 2013, we completed an offering of Senior Notes in the total principal amount of US$500 million, which have a total principal balance of $506.5 million as of December 31, 2016. The Senior Notes are due May 1, 2021 and bear interest at a rate of 6.875% per year from the most recent payment date to which interest has been paid or provided for. Interest on the Senior Notes is payable on May 1 and November 1 of each year, commencing November 1, 2013, and we have made all interest payments payable to date.

In the third quarter of 2015, we made a development decision to mine near surface, high grade portions of the silver and gold deposits at our San Sebastian project in Mexico and commenced ore production at the end of 2015. As a result, San Sebastian generated positive cash flows in 2016. In January 2017, we initiated work to develop and rehabilitate underground access which, upon completion, would allow us to mine deeper portions of the deposits at San Sebastian. We anticipate San Sebastian will continue to generate positive cash flows in 2017 and 2018. However, our estimate of costs could change, and our ability to generate cash flow at San Sebastian could be impacted by changes in precious metals prices or other factors, and there can be no assurance that we will be able to develop and operate San Sebastian as anticipated.

As discussed in Note 9 of Notes to Consolidated Financial Statements, in February 2016 we entered into an equity distribution agreement under which we may issue and sell shares of our common stock from time to time having an aggregate offering price of up to $75 million, with the net proceeds available for general corporate purposes. 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, and the agreement can be terminated by us at any time. As of December 31, 2016, we had sold 2,780,087 shares through the at-the-market program for net proceeds of $8.1 million.

Pursuant to our common stock dividend policy described in Note 9 of Notes to Consolidated Financial Statements, our Board of Directors declared and paid dividends on common stock totaling $3.9 million in 2016, $3.7 million in 2015, and $3.5 million in 2014. On February 21, 2017, our Board of Directors declared a dividend on common stock totaling $1.0 million payable in March 2017. Our dividend policy has a silver-price-linked component which ties the amount of declared common stock dividends to our realized silver price for the preceding quarter. Another component of our common stock dividend policy anticipates paying an annual minimum dividend. The declaration and payment of dividends on common stock is at the sole discretion of our board of directors, and there can be no assurance that we will continue to declare and pay common stock dividends in the future.

On May 8, 2012, we announced that our board of directors approved a stock repurchase program. Under the program, we are authorized to repurchase up to 20 million shares of our outstanding common stock from time to time in open market or privately negotiated transactions, depending on prevailing market conditions and other factors. The repurchase program may be modified, suspended or discontinued by us at any time. Whether or not we engage in repurchases from time to time may depend on a variety of factors, including not only price and cash resources, but customary black-out restrictions, whether we have any material inside information, limitations on share repurchases or cash usage that may be imposed by our credit agreement or in connection with issuances of securities, alternative uses for cash, applicable law, and other investment opportunities from time to time. As of December 31, 2016, 934,100 shares have been purchased in prior periods at an average price of $3.99 per share, leaving 19.1 million shares that may yet be purchased under the program. The closing price of our common stock at February 20, 2017, was $6.58 per share.

We may defer some capital investment 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. There can be no assurance that such financing will be available to us.

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 full availability of our $100 million revolving credit facility, we believe our cash, cash equivalents, investments, projected cash from operations, and availability of financing (including equity issuances), if needed, will be adequate to meet our obligations and other potential cash requirements during the next 12 months. Our obligations and other uses of cash may include, but are not limited to: debt service obligations related to the Senior Notes, 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 that a total of between $120 million and $125 million will be spent on capital expenditures, primarily for equipment, infrastructure, and development at our mines, in 2017. We also estimate that exploration and pre-development expenditures will total between $20 million and $25 million in 2017. However, capital, exploration, and pre-development expenditures 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 costs, sources of liquidity available to us, and other factors. A sustained downturn in metals prices or significant increase in operational or capital costs, other uses of cash, or other factors beyond our control could impact our plans.

Cash provided by operating activities increased by $118.9 million in 2016 compared to 2015. The increase is due to income, adjusted for non-cash items, being higher by $106.0 million. The higher income is primarily due to gross profit generated at San Sebastian following commencement of production there in December 2015, improved metals production at Greens Creek, Lucky Friday, and Casa Berardi, and higher average metals prices. In addition, working capital and other operating asset and liability changes resulted in a net increase in cash flows of $22.5 million in 2016 compared to an increase of $9.6 million in 2015. Significant variances in working capital changes between 2016 and 2015 resulted from from settlement of the reclamation insurance policy for the Troy mine for cash proceeds of $16.0 million and higher incentive compensation accruals. These variances were partially offset by net payments totaling $9.9 million by CoCa Mines, Inc., our wholly-owned subsidiary, for settlement of response costs at the Gilt Edge and Nelson Tunnel/Commodore sites, higher accounts receivable and inventory balances, and lower accrued taxes.

Cash provided by operating activities increased by $23.3 million in 2015 compared to 2014. The increase in 2015 was due to working capital and other operating asset and liability changes that resulted in a net increase in cash flows of $9.6 million in 2015 compared to a decrease in cash flows of $51.1 million in 2014. Significant variances in working capital changes between 2015 to 2014 included payments of approximately $55.4 million in the third quarter of 2014 to satisfy the remaining obligation under the Coeur d'Alene Basin environmental litigation settlement, primarily with proceeds from the exercise of warrants to purchase our common stock (see Note 4 of Notes to Consolidated Financial Statements for more information), and higher accounts payable balances due to increased capital spending at the end of 2015. These variances were partially offset by an increased portion of incentive compensation related to prior-period performance paid in cash in 2015 rather than stock, and higher accounts receivable balances due to the timing of sales. In addition, income, as adjusted for non-cash items, was lower by $37.4 million in 2015 compared to 2014 due primarily to lower metals prices.

Capital expenditures, excluding non-cash lease additions of $2.3 million, were $164.8 million in 2016, which was $27.3 million higher than capital expenditures in 2015. The increase was primarily related to higher costs at Casa Berardi for development of the new EMCP pit, a tailings dam raise project, underground development, and machinery and equipment. We purchased marketable securities having a cost basis of $48.9 million during 2016, with all but $0.9 million related to purchases of bonds having maturities of greater than 90 days and less than 365 days. Bonds valued at $18.6 million matured during 2016. We had a net cash outflow of $3.9 million for the purchase of Mines Management in 2016, and $0.8 million for the purchase of Revett in 2015.

We invested $137.4 million in capital expenditures in 2015, excluding $5.1 million in non-cash capital lease additions, compared to $122.5 million, excluding $9.5 million in capital leases, in 2014. The increase was primarily related to tailings facility expansion at Greens Creek, higher costs incurred for the #4 Shaft project at Lucky Friday, and open pit development and mill rehabilitation costs in support of start-up at San Sebastian, partially offset by the completion of the shaft deepening project at Casa Berardi in 2014. During 2014, restricted investments related to reclamation bonding at the Casa Berardi unit decreased by $4.3 million, with no change to our restricted cash balances during 2015. We purchased marketable securities having a cost basis of $0.9 million and $0.6 million during 2015 and 2014, respectively.

We received $54.4 million in proceeds from the exercise of warrants during 2014, as discussed above. During 2016, 2015, and 2014, we paid cash dividends on our common stock totaling $3.9 million, $3.7 million, and $3.5 million, respectively. We also paid cash dividends of $0.6 million on our Series B preferred stock during each of those years. We made payments on our capital leases of $8.4 million, $10.0 million, and $9.1 million, in 2016, 2015, and 2014, respectively, and payments on debt of $2.7 million and $0.9 million in 2016 and 2015, respectively. We also purchased shares of our common stock for $4.4 million, $1.9 million, and $3.7 million in 2016, 2015, and 2014, respectively, with $1.5 million of the amount in 2014 related to our stock repurchase program discussed above, and the remaining amounts for each year primarily related to the election by employees to satisfy tax withholding obligations for the vesting of restricted stock units through net share settlement.

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, outstanding purchase orders, certain capital expenditures, our credit facility, and lease arrangements as of December 31, 2016 (in thousands):

|  | Payments Due By Period |
|  | Less than 1 year |  |  | 1-3 years |  |  | 3-5 years |  |  | After 5 years |  |  | Total |

(1) | Consist of open purchase orders of approximately $10.0 million at the Greens Creek unit, $0.7 million at the Lucky Friday unit and $2.1 million at the Casa Berardi unit.

(2) | We have a $100 million revolving credit agreement under which we are required to pay a standby fee of 0.5% per annum on undrawn amounts under the revolving credit agreement. There was no amount drawn under the revolving credit agreement as of December 31, 2016, and the amounts above assume no amounts will be drawn during the agreement's term. For more information on our credit facility, see Note 6 of Notes to Consolidated Financial Statements.

(3) | As of December 31, 2016, we were committed to approximately $0.4 million in expenditures for various items.

(4) | Includes scheduled capital lease payments of $4.2 million, $3.2 million and $4.7 million (including interest), respectively, for equipment at our Greens Creek, Lucky Friday and Casa Berardi units. These leases have fixed payment terms and contain bargain purchase options at the end of the lease periods. See Note 6 of Notes to Consolidated Financial Statements for more information.

(5) | We enter into operating leases in the normal course of business. Substantially all lease agreements have fixed payment terms based on the passage of time. Some lease agreements provide us with the option to renew the lease or purchase the leased property. Our future operating lease obligations would change if we exercised these renewal options and if we entered into additional operating lease arrangements.

(6) | We sponsor defined benefit pension plans covering substantially all U.S. employees and provide certain post-retirement benefits for qualifying retired employees, along with a supplemental executive retirement plan. These amounts represent our estimate of the future funding requirements for these plans. We believe we will have funding requirements related to our defined benefit plans beyond one year; however, such obligations are not fixed in nature and are difficult to estimate, as they involve significant assumptions. See Note 8 of Notes to Consolidated Financial Statements for more information.

(7) | On April 12, 2013, we completed an offering of $500 million in aggregate principal amount of our Senior Notes due May 1, 2021. See Note 6 of Notes to Consolidated Financial Statements for more information. The Senior Notes bear interest at a rate of 6.875% per year from the date of original issuance or from the most recent payment date to which interest has been paid or provided for. Interest on the Senior Notes is payable on May 1 and November 1 of each year, commencing November 1, 2013, and we have made all interest payments payable to date. Since the initial offering, we have issued an additional $6.5 million in aggregate principal amount of the Senior Notes to fund obligations under our defined benefit pension plans. See Note 6 and Note 8 of Notes to Consolidated Financial Statements for more information.

We record liabilities for costs associated with mine closure, reclamation of land and other environmental matters. At December 31, 2016, our liabilities for these matters totaled $85.6 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 4 of Notes to Consolidated Financial Statements and Item 1A. Risk Factors – Our environmental obligations may exceed the provisions we have made.

Off-Balance Sheet Arrangements

At December 31, 2016, we had no existing off-balance sheet arrangements, as defined under SEC regulations, that have or are reasonably likely to have a current or future effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Critical Accounting Estimates

Our significant accounting policies are described in Note 1 of Notes to Consolidated Financial Statements. As described in Note 1, 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 accounting for business combinations, as they require us to make assumptions that were highly uncertain at the time the accounting estimates were 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 and equipment, deferred tax assets, and certain accounts receivable. Metals prices are also an important component in the estimation of reserves. As shown under Item 1A. - Risk Factors, 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 is influenced by various 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 the change in presidency in the U.S., Britain's exit from the European Union and a global economic recovery, including 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 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. However, China has recently experienced a lower rate of economic growth which is ongoing and could continue in the near term. 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 value because of low prices, and we can offer no assurance that prices will either remain at their current levels or increase.

Table of Contents

Processes supporting valuation of our assets and liabilities that are most significantly affected by prices include analysis of asset carrying values, depreciation, reserves, 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, below, regarding prices used for reserve 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 (see Business Combinations below).

Sales of concentrates sold directly to customers are recorded as revenues when title and risk of loss transfer to the customer (generally at the time of shipment) at estimated forward metals prices for the estimated month of settlement. Due to the time elapsed between the time of 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 metals 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 part N. Revenue Recognition of Note 1 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. These contracts do not qualify for hedge accounting and are therefore marked-to-market through earnings each period. 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 recognized in earnings.

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, and on at least an annual basis - and more frequently if warranted - management reviews our liabilities with our Audit Committee. 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. See Item 1A. Risk Factors – Our environmental obligations may exceed the provisions we have made.

Mineral Reserves

Critical estimates are inherent in the process of determining our reserves. Our reserves are affected largely by our assessment of future metals prices, as well as by engineering and geological estimates of ore grade, accessibility and production cost. Metals prices are estimated at long-term averages, as described in Item 2. - Property Descriptions. Our assessment of reserves occurs at least annually, and periodically utilizes external audits.

79

Table of Contents

Reserves 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 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 also play a key role in the valuation of certain assets in the determination of the purchase price allocations for acquisitions (see Business Combinations below). Reserves 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.

Business Combinations

We are required to allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The valuation of assets acquired and liabilities assumed requires management to make significant estimates and assumptions, especially with respect to long-lived assets (including mineral assets beyond the known reserves); these include estimates of future metals prices and mineral reserves, as discussed above. Management may also be required to make estimates related to the valuation of deferred tax assets or liabilities as part of the purchase price allocation for business combinations. In some cases, we use third-party appraisers to determine the fair values and lives of property and other identifiable assets. In addition, costs related to business combinations are included in earnings as incurred, and our financial results for periods in which business combinations are pursued could be adversely affected as a result.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09 Revenue Recognition, replacing guidance currently codified in Subtopic 605-10 Revenue Recognition-Overall with various SEC Staff Accounting Bulletins providing interpretive guidance. The new ASU establishes a new five step principle-based framework in an effort to significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. In August 2015, the FASB issued ASU No. 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. ASU No. 2015-14 defers the effective date of ASU No. 2014-09 until annual and interim reporting periods beginning after December 15, 2017.

We have performed a preliminary assessment of the impact of implementation of ASU No. 2014-09, and do not believe it will change the timing of revenue recognition or amounts of revenue recognized compared to how we recognize revenue under our current policies. Our revenues involve a relatively limited number of types of contracts and customers. In addition, our revenue contracts do not involve multiple types of performance obligations. Revenues from doré are recognized, and the transaction price is known, at the time the metals sold are delivered to the customer. Concentrate revenues are generally recognized at the time of shipment. Concentrates sold at our Lucky Friday unit typically leave the mine and are received by the customer within the same day. There is a period of time between shipment of concentrates from our Greens Creek unit and their physical receipt by the customer. However, based on our assessment, we believe control of the concentrate parcels is generally obtained by the customer at the time of shipment.

Our concentrate sales involve variable consideration, as they are subject to changes in metals prices between the time of shipment and their final settlement. However, we are able to reasonably estimate the transaction price for the concentrate sales at the time of shipment using forward prices for the month of settlement, and we then adjust the values each period until final settlement. Also, it is unlikely a significant reversal of revenue for any one concentrate parcel will occur.

Table of Contents

During 2017, we plan to finalize our assessment of the impact of ASU No. 2014-09 on our revenue recognition, and assess the additional disclosure requirements under the new guidance.

In April 2015, the FASB issued ASU No. 2015-03 Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for fiscal years beginning after December 15, 2015. ASU No. 2015-03 did not have a material impact on our consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-11 Inventory (Topic 330): Simplifying the Measurement of Inventory. The update provides for inventory to be measured at the lower of cost and net realizable value, and is effective for fiscal years beginning after December 15, 2016. We do not expect this update to have a material impact on our consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17 Income Taxes - Balance Sheet Classification of Deferred Taxes (Topic 740). The update is designed to reduce complexity of reporting deferred income tax liabilities and assets into current and non-current amounts in a statement of financial position. ASU No. 2015-17 requires the presentation of deferred income taxes, changes to deferred tax liabilities and assets be classified as non-current in the statement of financial position. The update is effective for fiscal years beginning after December 15, 2016. ASU No. 2015-17. Our current deferred tax asset balance at December 31, 2016 was $12.3 million, which would be reclassified as non-current under ASU No. 2015-17.

In January 2016, the FASB issued ASU No. 2016-01 Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that are not accounted for under the equity method at fair value, with any changes in fair value included in current earnings, and updates certain disclosure requirements. The update is effective for fiscal years beginning after December 15, 2017. We are currently evaluating the impact of implementing this update on our consolidated financial statements. At December 31, 2016, we had net unrealized gains of $1.8 million related to equity investments included in accumulated other comprehensive loss.

In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842). The update modifies the classification criteria and requires lessees to recognize the assets and liabilities on the balance sheet for most leases. The update is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of implementing this update on our consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The update simplifies the accounting for stock-based compensation, including income tax consequences and balance sheet and cash flow statement classification of awards. The update is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the potential impact of implementing this update on our consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update provides guidance on classification for cash receipts and payments related to eight specific issues. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We do not expect this update to have a material impact on our consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash. The update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the potential impact of implementing this update on our consolidated financial statements.

81

Table of Contents

In January 2017, the FASB issued ASU No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business. The update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. We will apply the provisions of the update to potential future acquisitions occurring after the effective date.

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 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, 2016, which are sensitive to changes in commodity prices and foreign exchange 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).

Provisional Sales

Sales of all metals products sold directly to customers, including by-product metals, are recorded as revenues when title and risk of loss transfers to the customer. 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 concentrates 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, 2016, metals contained in concentrates and exposed to future price changes totaled approximately 1.4 million ounces of silver, 4,679 ounces of gold, 10,166 tons of zinc, and 4,052 tons of lead. If the price for each metal were to change by ten percent, the change in the total value of the concentrates sold would be approximately $5.9 million. However, as discussed in Commodity-Price Risk Management below, we utilize a program designed and intended to mitigate the risk of negative price adjustments with limited mark-to-market financially-settled forward contracts for our silver, gold, zinc and lead sales.

Commodity-Price Risk Management

At times, we may 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 which 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 the market. 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 hedged under such programs. 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.

Table of Contents

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. These contracts do not qualify for hedge accounting and are marked-to-market through earnings each period. At December 31, 2016, we recorded a current asset of $2.8 million, which is included in other current assets and is net of $0.7 million for contracts in a fair value current liability position. In addition, we recorded a non-current asset of $2.5 million at December 31, 2016 which is included in other non-current assets.

We recognized a $14.2 million net loss during 2016 on the contracts utilized to manage exposure to prices of metals in our concentrate shipments, which is included in sales of products. The net loss recognized on the contracts offsets gains 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 $4.4 million net gain during 2016 on the contracts utilized to manage exposure to prices for forecasted future concentrate shipments. The net gain on these contracts is included as a separate line item under other income (expense), as they relate to forecasted future shipments, as opposed to sales that have already taken place but are subject to final pricing as discussed in the preceding paragraph. The net gain for 2016 is the result of lower zinc and lead prices. This program, when utilized, is designed to mitigate the impact of potential future declines in lead and zinc prices from the price levels established in the contracts (see average price information below).

The following tables summarize the quantities of metals committed under forward sales contracts at December 31, 2016:

December 31, 2016 |  | Ounces/pounds under contract (in 000's) |  |  | Average price per ounce/pound |
|  | Silver |  |  | Gold |  |  | Zinc |  |  | Lead |  |  | Silver |  |  | Gold |  |  | Zinc |  |  | Lead |

Foreign Currency

We operate or have mining interests in Canada and Mexico, which exposes us to risks associated with fluctuations in the exchange rates between the U.S. dollar ("USD") and the Canadian dollar ("CAD") and Mexican peso ("MXN"). We have determined that the functional currency for our Canadian and Mexican operations is the USD. As such, foreign exchange gains and losses associated with the re-measurement of monetary assets and liabilities from CAD and MXN to USD are recorded to earnings each period. For the year ended December 31, 2016, we recognized a net foreign exchange loss of $2.9 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, 2016 would have resulted in a change of approximately $13.9 million in our net foreign exchange gain or loss. A 10% change in the exchange rate between the USD and MXN from the rate at December 31, 2016 would have resulted in an immaterial change in our net foreign exchange gain or loss.

In April 2016, we initiated 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 October 2016, we also initiated a program to manage our exposure to the impact of fluctuations in the exchange rate between the USD and MXN on our future operating costs denominated in MXN. The programs utilize forward contracts to sell CAD and MXN, and each contract is designated as a cash flow hedge. As of December 31, 2016, we have 130 forward contracts outstanding to sell CAD$290.1 million having a notional amount of US$222.9 million, and 24 forward contracts outstanding to sell MXN$202.5 million having a notional amount of US$10.3 million. The CAD contracts represent between 21% and 75% of our annual forecasted cash operating costs at Casa Berardi from 2017 through 2020 and have CAD-to-USD exchange rates ranging between 1.2787 and 1.3380. The MXN contracts represent 75% of our forecasted cash operating costs at San Sebastian for 2017 and have MXN-to-USD exchange rates ranging between 18.9975 and 21.000. Our risk management policy allows for up to 75% of our planned cost exposure for five years into the future to be hedged under such programs, and for potential additional programs to manage other foreign currency-related exposure areas.

Table of Contents

As of December 31, 2016, we recorded the following balances for the fair value of the contracts:

• a non-current asset of $27 thousand, which is included in other non-current assets;

• a current liability of $2.8 million, which is included in other current liabilities, and

• a non-current liability of $2.4 million, which is included in other non-current liabilities.

Net unrealized losses of approximately $5.2 million related to the effective portion of the hedges were included in accumulated other comprehensive income as of December 31, 2016, and are net of related deferred taxes. 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 $3.0 million in net unrealized losses included in accumulated other comprehensive income as of December 31, 2016 would be reclassified to current earnings in the next twelve months. Net unrealized losses of approximately $2 thousand related to ineffectiveness of the hedges were included in gain (loss) on derivatives contracts on our consolidated statements of operations and comprehensive income (loss) for the year ended December 31, 2016.

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.

85

Table of Contents

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016, 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, 2016, based on these criteria.

Our internal control over financial reporting as of December 31, 2016 has been audited by BDO USA, LLP, 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, 2016, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Hecla Mining Company

Coeur d’Alene, Idaho

We have audited Hecla Mining Company’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Hecla Mining Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A, Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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.

In our opinion, Hecla Mining Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Hecla Mining Company as of December 31, 2016 and 2015, and 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, 2016 and our report dated February 23, 2017 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

Hecla Mining Company

Coeur d’Alene, Idaho

We have audited the accompanying consolidated balance sheets of Hecla Mining Company (the “Company”) as of December 31, 2016 and 2015 and 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, 2016. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Hecla Mining Company at December 31, 2016 and 2015, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2016, 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), Hecla Mining Company’s internal control over financial reporting as of December 31, 2016, 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 23, 2017 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements

Note 1: Summary of Significant Accounting Policies

A. Principles of Consolidation — Our Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America, and include our accounts and our wholly-owned subsidiaries’ accounts. All significant inter-company balances and transactions have been eliminated in consolidation.

B. Assumptions and Use of Estimates — Preparing 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. We consider our most critical accounting estimates to be future metals prices; obligations for environmental, reclamation and closure matters; mineral reserves; and valuation of business combinations. Other significant areas requiring the use of management assumptions and estimates relate to reserves for contingencies and litigation; asset impairments, including long-lived assets and investments; valuation of deferred tax assets; and post-employment, post-retirement and other employee benefit assets and liabilities. We have based our estimates on historical experience and on various other assumptions that we believe to be reasonable. Accordingly, actual results may differ materially from these estimates under different assumptions or conditions.

C. Cash and Cash Equivalents — Cash and cash equivalents consist of all cash balances and highly liquid investments with a remaining maturity of three months or less when purchased and are carried at fair value. Cash and cash equivalents are invested in money market funds, certificates of deposit, U.S. government and federal agency securities, municipal securities and corporate bonds.

D. Investments and Securities Held for Sale — We determine the appropriate classification of our investments at the time of purchase and re-evaluate such determinations at each reporting date. Short-term investments include certificates of deposit and held to maturity debt securities, based on our intent and ability to hold the securities to maturity. Held to maturity securities are carried at amortized cost. Marketable debt and equity securities are categorized as available for sale and carried at fair market value.

Realized gains and losses on the sale of securities are recognized on a specific identification basis. Unrealized gains and losses are included as a component of accumulated other comprehensive income (loss), unless an other than temporary impairment in value has occurred or we have elected the fair value option accounting method when available for certain investments; in either of those cases, the unrealized gain or loss would be charged to current period net income (loss). The fair value option allows for the fair value measurement of specified assets or liabilities on a case-by-case basis. The fair value option may be elected when an investment becomes subject to the equity method of accounting. In determining whether our investments are subject to the equity method of accounting, we evaluate whether our ownership percentage and other factors indicate that we have the ability to exercise significant influence in the financial and/or operational decisions of the investee. We have elected the fair value option under such circumstances in the past and may do so in the future. Unrealized gains and losses originally included in accumulated other comprehensive income are reclassified to current period net income (loss) when the sale of securities, determination of an other than temporary impairment, or election of the fair value option accounting method occurs.

E. Inventories — Major types of inventories include materials and supplies and metals product inventory, which is determined by the stage at which the ore is in the production process (stockpiled ore and finished goods). Product inventories are stated at the lower of full cost of production or estimated net realizable value based on current metal prices. Materials and supplies inventories are stated at cost.

Stockpiled ore inventory represents ore that has been mined, hauled to the surface, and is available for further processing. Stockpiles are measured by estimating the number of tons added and removed from the stockpile, the amount of contained metal ounces or pounds (based on assay data) and the estimated metallurgical recovery rates (based on the expected processing method). Costs are allocated to a stockpile based on relative values of material stockpiled and processed using current mining costs incurred up to the point of stockpiling the ore, including applicable overhead, depreciation, depletion and amortization relating to mining operations, and removed at each stockpile’s average cost per recoverable unit.

Finished goods inventory includes doré and concentrates at our operations, doré in transit to refiners or at refiners waiting to be processed, and bullion in our accounts at refineries.

F. Restricted Cash — Restricted cash and investments primarily represent investments in money market funds, certificates of deposit, and bonds of U.S. government agencies and are restricted primarily for reclamation funding or surety bonds. Restricted cash balances are carried at fair value.

G. Properties, Plants and Equipment – Costs are capitalized when it has been determined an ore body can be economically developed. The development stage begins at new projects when our management and/or board of directors makes the decision to bring a mine into commercial production, and ends when the production stage, or exploitation of reserves, begins. Expenditures incurred during the development and production stages for new assets, new facilities, alterations to existing facilities that extend the useful lives of those facilities, and major mine development expenditures are capitalized, including primary development costs such as costs of building access ways, shaft sinking, lateral development, drift development, ramps and infrastructure developments. Costs to improve, alter, or rehabilitate primary development assets which appreciably extend the life, increase capacity, or improve the efficiency or safety of such assets are also capitalized.

The cost of removing overburden and waste materials to access the ore body at an open-pit mine prior to the production stage are referred to as "pre-stripping costs." Pre-stripping costs are capitalized during the development stage. Where multiple open pits exist at an operation utilizing common facilities, pre-stripping costs are capitalized at each pit. The production stage of a mine commences when salable materials, beyond a de minimis amount, are produced. Stripping costs incurred during the production stage are treated as variable production costs included as a component of inventory, to be recognized in cost of sales and other direct production costs in the same period as the revenue from the sale of inventory.

Costs for exploration, pre-development, secondary development at operating mines, including drilling costs related to those activities (discussed further below), and maintenance and repairs on capitalized property, plant and equipment are charged to operations as incurred. Exploration costs include those relating to activities carried out (a) in search of previously unidentified mineral deposits, (b) at undeveloped concessions, or (c) at operating mines already containing proven and probable reserves, where a determination remains pending as to whether new target deposits outside of the existing reserve areas can be economically developed. Pre-development activities involve costs incurred in the exploration stage that may ultimately benefit production, such as underground ramp development, which are expensed due to the lack of evidence of economic development, which is necessary to demonstrate future recoverability of these expenses. At an underground mine, secondary development costs are incurred for preparation of an ore body for production in a specific ore block, stope or work area, providing a relatively short-lived benefit only to the mine area they relate to, and not to the ore body as a whole.

Drilling and related costs are either classified as exploration or secondary development, as defined above, and charged to operations as incurred, or capitalized, based on the following criteria:

| • | whether the costs are incurred to further define mineralization at and adjacent to existing reserve areas or intended to assist with mine planning within a reserve area;

| • | whether the drilling costs relate to an ore body that has been determined to be commercially mineable, and a decision has been made to put the ore body into commercial production; and

| • | whether, at the time that the cost is incurred: (a) the expenditure embodies a probable future benefit that involves a capacity, singly or in combination, with other assets to contribute directly or indirectly to future net cash inflows, (b) we can obtain the benefit and control others’ access to it, and (c) the transaction or event giving rise to our right to or control of the benefit has already occurred.

F-8

Table of Contents

If all of these criteria are met, drilling and related costs are capitalized. Drilling costs not meeting all of these criteria are expensed as incurred. The following factors are considered in determining whether or not the criteria listed above have been met, and capitalization of drilling costs is appropriate:

| • | completion of a favorable economic study and mine plan for the ore body targeted;

| • | authorization of development of the ore body by management and/or the board of directors; and

| • | all permitting and/or contractual requirements necessary for us to have the right to or control of the future benefit from the targeted ore body have been met.

Drilling and related costs of approximately $6.8 million, $6.7 million, and $5.3 million for the years ended December 31, 2016, 2015 and 2014, respectively, met our criteria for capitalization listed above at our properties that are in the production stage.

When assets are retired or sold, the costs and related allowances for depreciation and amortization are eliminated from the accounts and any resulting gain or loss is reflected in current period net income (loss). Idle facilities placed on standby are carried at the lower of net carrying value or estimated net realizable value. The net carrying values of idle facilities on standby are written-down to salvage value upon reaching the end of the economic life. Therefore, with the exception of depreciation recorded on mobile equipment used in ongoing exploration and reclamation efforts at such properties, we do not record depreciation on idle facilities when they are not in operation.

Included in properties, plants, equipment and mineral interests on our consolidated financial statements are mineral interests, which are tangible assets that include acquired undeveloped mineral interests and royalty interests. Undeveloped mineral interests include: (i) mineralized material and other resources which are measured, indicated or inferred with insufficient drill spacing or quality to qualify as proven and probable reserves; and (ii) inferred material not immediately adjacent to existing proven and probable reserves but accessible within the immediate mine infrastructure. Residual values for undeveloped mineral interests represent the expected fair value of the interests at the time we plan to convert, develop, further explore or dispose of the interests and are evaluated at least annually.

We capitalize portions of interest costs incurred on our debt as a part of the cost of constructing or acquiring certain qualifying assets. The amount of interest capitalized represents the portion of interest cost incurred during the construction or acquisition periods that theoretically could have been avoided if expenditures for the qualifying assets had not been made, limited to the total interest cost actually incurred during the period. Qualifying assets include discrete projects constructed by us or by a third party for our use which required a period of time to prepare the assets for their intended use. Interest capitalization takes place when capital expenditures for qualifying assets have been incurred, activities to prepare the qualifying asset for its intended use are underway, and interest cost is being incurred.

H. Depreciation, Depletion and Amortization — Capitalized costs are depreciated or depleted using the straight-line method or unit-of-production method at rates sufficient to depreciate such costs over the shorter of estimated productive lives of such facilities or the useful life of the individual assets. Productive lives range from 1 to 22 years, but do not exceed the useful life of the individual asset. Determination of expected useful lives for amortization calculations are made on a property-by-property or asset-by-asset basis at least annually. Our estimates for reserves, mineralized material, and other resources are a key component in determining our units of production depreciation rates. Our estimates of proven and probable ore reserves, mineralized material, and other resources may change, possibly in the near term, resulting in changes to depreciation, depletion and amortization rates in future reporting periods.

Undeveloped mineral interests and value beyond proven and probable reserves are not amortized until such time as there are proven and probable reserves or the related mineralized material is converted to proven and probable reserves. At that time, the basis of the mineral interest is amortized on a units-of-production basis. Pursuant to our policy on impairment of long-lived assets (discussed further below), if it is determined that an undeveloped mineral interest cannot be economically converted to proven and probable reserves, the basis of the mineral interest is reduced to its net realizable value and an impairment loss is recorded to expense in the period in which it is determined to be impaired.

F-9

Table of Contents

I. Impairment of Long-lived Assets — Management reviews and evaluates the net carrying value of all facilities, including idle facilities, for impairment upon the occurrence of events or changes in circumstances that indicate that the related carrying amounts may not be recoverable. We estimate the net realizable value of each property based on the estimated undiscounted future cash flows that will be generated from operations at each property, the estimated salvage value of the surface plant and equipment, and the value associated with property interests.

Although management has made a reasonable estimate of factors based on current conditions and information, assumptions underlying future cash flows are subject to significant risks and uncertainties. Estimates of undiscounted future cash flows are dependent upon, among other factors, estimates of: (i) metals to be recovered from proven and probable ore reserves and, to some extent, identified mineralization and other resources beyond proven and probable reserves, (ii) future production and capital costs and (iii) estimated metals prices (considering current and historical prices, forward pricing curves and related factors) over the estimated remaining mine life. It is reasonably possible that changes could occur in the near term that could adversely affect our estimate of future cash flows to be generated from our operating properties. If estimated undiscounted cash flows are less than the carrying value of a property, an impairment loss is recognized for the difference between the carrying value and fair value of the property.

J. Proven and Probable Ore Reserves — At least annually, management reviews the reserves used to estimate the quantities and grades of ore at our mines which we believe can be recovered and sold economically. Management’s calculations of proven and probable ore reserves are based on financial, engineering and geological estimates, including future metals prices and operating costs. From time to time, management obtains external audits of reserves. An independent review of the modeling process at Greens Creek was performed during 2016.

Reserve estimates will change as existing reserves are depleted through production and as production costs and/or metals prices change. A significant drop in metals prices may reduce reserves by making some portion of such ore uneconomic to develop and produce. Changes in reserves may also reflect that actual grades of ore processed may be different from stated reserve grades because of variation in grades in areas mined, mining dilution and other factors. Our reserve estimates may change based on actual production experience. It is reasonably possible that certain of our estimates of proven and probable ore reserves will change in the near term, which could result in a change to estimated future cash flows, associated carrying values of the asset and amortization rates in future reporting periods, among other things.

Declines in the market prices of metals, increased production or capital costs, reduction in the grade or tonnage of the deposit or an increase in the dilution of the ore or reduced recovery rates may render ore reserves uneconomic to exploit. If our realized price for the metals we produce were to decline substantially below the levels set for calculation of reserves for an extended period, there could be material delays in the development of new projects, net losses, reduced cash flow, restatements or reductions in reserves and asset write-downs in the applicable accounting periods. Reserves should not be interpreted as assurances of mine life or of the profitability of current or future operations. No assurance can be given that the estimate of the amount of metal or the indicated level of recovery of these metals will be realized.

K. Pension Plans and Other Post-retirement Benefits — Accounting principles regarding employers’ accounting for defined benefit pension and other post-retirement plans, among other things, require us to:

| • | recognize the funded status of our defined benefit plans in our consolidated financial statements; and

| • | recognize as a component of other comprehensive income (loss) the actuarial gains and losses and prior service costs and credits that arise during the period but are not immediately recognized as components of net periodic benefit cost.

L. Income and Production Taxes — We provide for federal, state and foreign income taxes currently payable, as well as those deferred due to timing differences between reporting income and expenses for financial statement purposes versus tax purposes. Federal, state and foreign tax benefits are recorded as a reduction of income taxes, when applicable. We record deferred tax liabilities and assets for expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax bases of those assets and liabilities, as well as operating loss and tax credit carryforwards, using enacted tax rates in effect in the years in which the differences are expected to reverse.

F-10

Table of Contents

We evaluate uncertain tax positions in a two-step process, whereby (i) it is determined whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the related tax authority would be recognized.

We classify mine license taxes incurred in the states of Alaska and Idaho as other direct production costs reported in our gross profits. Resource taxes incurred in Quebec, Canada are classified as income taxes.

For additional information, see Note 5 — Income Taxes.

M. Reclamation and Remediation Costs (Asset Retirement Obligations) — At our operating properties, we record a liability for the present value of our estimated environmental remediation costs, and the related asset created with it, in the period in which the liability is incurred. The liability is accreted and the asset is depreciated over the life of the related assets. Adjustments for changes resulting from the passage of time and changes to either the timing or amount of the original present value estimate underlying the obligation are made in the period incurred.

At our non-operating properties, we accrue costs associated with environmental remediation obligations when it is probable that such costs will be incurred and they are reasonably estimable. Accruals for estimated losses from environmental remediation obligations have historically been recognized no later than completion of the remedial feasibility study for such facility and are charged to current earnings under provision for closed operations and environmental matters. Costs of future expenditures for environmental remediation are not discounted to their present value unless subject to a contractually obligated fixed payment schedule. Such costs are based on management’s current estimate of amounts to be incurred when the remediation work is performed, within current laws and regulations.

Future closure, reclamation and environmental-related expenditures are difficult to estimate in many circumstances, due to the early stage nature of investigations, uncertainties associated with defining the nature and extent of environmental contamination, the application of laws and regulations by regulatory authorities, and changes in reclamation or remediation technology. We periodically review accrued liabilities for such reclamation and remediation costs as evidence becomes available indicating that our liabilities have potentially changed. Changes in estimates at our non-operating properties are reflected in current period net income (loss).

It is reasonably possible the ultimate cost of reclamation and remediation could change in the future, and that changes to these estimates could have a material effect on future operating results as new information becomes known.

N. Revenue Recognition and Trade Accounts Receivable — Sales of all metals products sold directly to customers, including by-product metals, are recorded as revenues and accounts receivable when title and risk of loss transfer to the customer. For concentrate sales, revenues are generally recorded at the time of shipment at estimated forward prices for the anticipated month of settlement. Due to the time elapsed from shipment to the customer and the final settlement with the customer, we must estimate the prices at which sales of our concentrates will be settled. Previously recorded sales and accounts receivable are adjusted to estimated settlement metals prices until final settlement by the customer.

Sales and accounts receivable for concentrate shipments are recorded net of charges by the customers for treatment, refining, smelting losses, and other charges negotiated by us with the customers. Charges are estimated by us upon shipment of concentrates based on contractual terms, and actual charges typically do not vary materially from our estimates. Costs charged by customers include fixed treatment and refining costs per ton of concentrate, and also include price escalators which allow the customers to participate in the increase of lead and zinc prices above a negotiated baseline.

F-11

Table of Contents

Changes in metals prices between shipment of concentrates and final settlement will result in adjustments to revenues and accounts receivable related to sales of concentrate previously recorded upon shipment. Our concentrate sales and accounts receivable are based on provisional sales prices containing an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of the concentrates at the forward price at the time of the sale. The embedded derivative, which does not qualify for hedge accounting, is adjusted to market through earnings each period prior to final settlement.

At December 31, 2016, metals contained in concentrates and exposed to future price changes totaled 1.4 million ounces of silver, 4,679 ounces of gold, 10,166 tons of zinc, and 4,052 tons of lead. However, as discussed in P. Risk Management Contracts below, we seek to mitigate the risk of negative price adjustments by using financially-settled forward contracts for some of our sales.

Sales of metals in products tolled by refiners and sold directly by us, rather than sold to smelters, are recorded at contractual amounts when title and risk of loss transfer to the buyer.

Changes in the market price of metals significantly affect our revenues, profitability, and cash flow. Metals prices can and often do fluctuate widely and are affected by numerous factors beyond our control, such as political and economic conditions, demand, forward selling by producers, aggregation by metals speculators and others, expectations for inflation, central bank sales, custom smelter activities, the relative exchange rate of the U.S. dollar, investor sentiment, and global mine production levels. The aggregate effect of these factors is impossible to predict. Because our revenue is derived from the sale of silver, gold, lead, and zinc, our earnings are directly related to the prices of these metals.

O. Foreign Currency — The functional currency for our operations located in the U.S., Mexico and Canada was the U.S. dollar ("USD") for all periods presented. Accordingly, for the Casa Berardi unit in Canada and San Sebastian project in Mexico, we have translated our monetary assets and liabilities at the period-end exchange rate, and non-monetary assets and liabilities at historical rates, with income and expenses translated at the average exchange rate for the current period. All translation gains and losses have been included in the current period net income (loss). Expenses incurred at our foreign operations and denominated in Canadian dollars ("CAD") and Mexican pesos ("MXN") expose us to exchange rate fluctuations between those currencies and the USD. However, as discussed in P. Risk Management Contracts below, we seek to mitigate this exposure by using financially-settled forward contracts to sell CAD and MXN.

For the year ended December 31, 2016 we recognized a total net foreign exchange loss of $2.9 million. For the years ended December 31, 2015 and 2014, we recognized total net foreign exchange gains of $24.6 million and $11.5 million, respectively.

P. Risk Management Contracts — We use derivative financial instruments as part of an overall risk-management strategy utilized as a means of managing exposure to metals prices and exchange rate fluctuations between the USD and CAD and MXN. We do not hold or issue derivative financial instruments for speculative trading purposes. We measure derivative contracts as assets or liabilities based on their fair value. Amounts recognized for the fair value of derivative asset and liability positions with the same counterparty and which would be settled on a net basis are offset against each other on our consolidated balance sheets. Gains or losses resulting from changes in the fair value of derivatives in each period are recorded either in current earnings or other comprehensive income (“OCI”), depending on the use of the derivative, whether it qualifies for hedge accounting and whether that hedge is effective. Amounts deferred in OCI are reclassified to sales of products (for metals price-related contracts) or cost of sales (for foreign currency-related contracts). Ineffective portions of any change in fair value of a derivative are recorded in current period other operating income (expense). As of December 31, 2016, our foreign currency-related forward contracts qualified for hedge accounting, with unrealized gains and loss related to the effective portion of the contracts included in OCI. Our metals price-related forward contracts do not qualify for hedge accounting as of December 31, 2016, and all unrealized gains and losses are therefore reported in earnings.

See Note 10 for additional information on our foreign exchange and metal derivative contracts as of December 31, 2016.

Q. Stock Based Compensation — The fair values of equity instruments granted to employees and having vesting periods are expensed over the vesting periods on a straight-line basis. The fair values of instruments having no vesting period are expensed when granted. Stock-based compensation expense is recorded among general and administrative expenses, exploration and cost of sales and other direct production costs.

For additional information on our employee stock option and restricted stock unit compensation, see Note 9.

R. Legal Costs – Legal costs incurred in connection with a potential loss contingency are recorded to expense as incurred.

S. Basic and Diluted Income (Loss) Per Common Share — We calculate basic earnings per share on the basis of the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated using weighted average number of common shares outstanding during the period plus the effect of potential dilutive common shares during the period using the treasury stock and if-converted methods.

Potential dilutive common shares include outstanding stock options, unvested restricted stock awards, stock units, warrants and convertible preferred stock for periods in which we have reported net income. For periods in which we reported net losses, potential dilutive common shares are excluded, as their conversion and exercise would be anti-dilutive. See Note 13 for additional information.

T. Comprehensive Income (Loss) — In addition to net income (loss), comprehensive income (loss) includes certain changes in equity during a period, such as adjustments to minimum pension liabilities, adjustments to recognize the over-funded or under-funded status of our defined benefit pension plans, the change in fair value of derivative contracts designated as hedge transactions, and cumulative unrecognized changes in the fair value of available for sale investments, net of tax, if applicable.

U. Fair Value Measurements — We disclose the following information for each class of assets and liabilities that are measured at fair value:

| 1. | the fair value measurement;

| 2. | the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3);

| 3. | for fair value measurements using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following:

| a. | total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings, and a description of where those gains or losses included in earnings are reported in the statement of operations;

| b. | the amount of these gains or losses attributable to the change in unrealized gains or losses relating to those assets or liabilities still held at the reporting period date and a description of where those unrealized gains or losses are reported;

| c. | purchases, sales, issuances, and settlements (net); and

| d. | transfers into and/or out of Level 3.

| 4. | the amount of the total gains or losses for the period included in earnings that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date and a description of where those unrealized gains or losses are reported in the statement of operations; and

| 5. | in annual periods only, the valuation technique(s) used to measure fair value and a discussion of changes in valuation techniques, if any, during the period.

See Notes 8 and 12 for more information on the fair value measurement of our financial instruments.

V. Research and development — Costs related to research and development of technologies or equipment new to our operations are recorded to expense when it is uncertain whether future economic benefit will result from the costs. Such costs are capitalized if it can be determined they will result in future economic benefit through use of the new technology or equipment. Research and development costs to date as of December 31, 2016 include contractor fees.

W. New Accounting Pronouncements — In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09 Revenue Recognition, replacing guidance currently codified in Subtopic 605-10 Revenue Recognition-Overall with various SEC Staff Accounting Bulletins providing interpretive guidance. The new ASU establishes a new five step principle-based framework in an effort to significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. In August 2015, the FASB issued ASU No. 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. ASU No. 2015-14 defers the effective date of ASU No. 2014-09 until annual and interim reporting periods beginning after December 15, 2017.

We have performed a preliminary assessment of the impact of implementation of ASU No. 2014-09, and do not believe it will change the timing of revenue recognition or amounts of revenue recognized compared to how we recognize revenue under our current policies. Our revenues involve a relatively limited number of types of contracts and customers. In addition, our revenue contracts do not involve multiple types of performance obligations. Revenues from doré are recognized, and the transaction price is known, at the time the metals sold are delivered to the customer. Concentrate revenues are generally recognized at the time of shipment. Concentrates sold at our Lucky Friday unit typically leave the mine and are received by the customer within the same day. There is a period of time between shipment of concentrates from our Greens Creek unit and their physical receipt by the customer. However, based on our assessment, we believe control of the concentrate parcels is generally obtained by the customer at the time of shipment.

Our concentrate sales involve variable consideration, as they are subject to changes in metals prices between the time of shipment and their final settlement. However, we are able to reasonably estimate the transaction price for the concentrate sales at the time of shipment using forward prices for the month of settlement, and we then adjust the values each period until final settlement. Also, it is unlikely a significant reversal of revenue for any one concentrate parcel will occur.

During 2017, we plan to finalize our assessment of the impact of ASU No. 2014-09 on our revenue recognition, and assess the additional disclosure requirements under the new guidance.

In April 2015, the FASB issued ASU No. 2015-03 Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for fiscal years beginning after December 15, 2015. ASU No. 2015-03 did not have a material impact on our consolidated financial statements.

In July 2015, the FASB issued ASU No. 2015-11 Inventory (Topic 330): Simplifying the Measurement of Inventory. The update provides for inventory to be measured at the lower of cost and net realizable value, and is effective for fiscal years beginning after December 15, 2016. We do not expect this update to have a material impact on our consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17 Income Taxes - Balance Sheet Classification of Deferred Taxes (Topic 740). The update is designed to reduce complexity of reporting deferred income tax liabilities and assets into current and non-current amounts in a statement of financial position. ASU No. 2015-17 requires the presentation of deferred income taxes, changes to deferred tax liabilities and assets be classified as non-current in the statement of financial position. The update is effective for fiscal years beginning after December 15, 2016. Our current deferred tax asset balance at December 31, 2016 was $12.3 million, which would be reclassified as non-current under ASU No. 2015-17.

In January 2016, the FASB issued ASU No. 2016-01 Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that are not accounted for under the equity method at fair value, with any changes in fair value included in current earnings, and updates certain disclosure requirements. The update is effective for fiscal years beginning after December 15, 2017. We are currently evaluating the impact of implementing this update on our consolidated financial statements. At December 31, 2016, we had net unrealized gains of $1.8 million related to equity investments included in accumulated other comprehensive loss.

In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842). The update modifies the classification criteria and requires lessees to recognize the assets and liabilities on the balance sheet for most leases. The update is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of implementing this update on our consolidated financial statements. See Note 3 for information on our operating lease commitments as of December 31, 2016.

In March 2016, the FASB issued ASU No. 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The update simplifies the accounting for stock-based compensation, including income tax consequences and balance sheet and cash flow statement classification of awards. The update is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the impact of implementing this update on our consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update provides guidance on classification for cash receipts and payments related to eight specific issues. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the potential impact of implementing this update on our consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash. The update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the potential impact of implementing this update on our consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business. The update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. We will apply the provisions of the update to potential future acquisitions occurring after the effective date.

Note 2. Investments

Investments

Our current investments, which are classified as "available for sale" and consist of bonds having maturities of greater than 90 days and less than 365 days, had a fair value of $29.1 million at December 31, 2016. During 2016, we had purchases of such investments of $48.0 million and maturities of $18.6 million. We held no such investments as of December 31, 2015. Our current investments at December 31, 2016 consist of the following:

|  | Amortized cost |  |  | Unrealized loss |  |  | Fair market value |
Corporate bonds |  | $ | 22,100 |  |  | $ | (46 | ) |  | $ | 22,054 |

Total |  | $ | 29,166 |  |  | $ | (49 | ) |  | $ | 29,117 |

At December 31, 2016 and 2015, the fair value of our non-current investments was $5.0 million and $1.5 million, respectively. Our non-current investments consist of marketable equity securities which are carried at fair value, and are primarily classified as “available-for-sale.” The cost basis of our non-current investments was approximately $4.1 million and $4.0 million at December 31, 2016 and 2015, respectively. In each of 2016 and 2015, we acquired marketable equity securities having a cost basis of $0.9 million. In 2016 and 2015, we recognized impairment charges against current earnings of $1.0 million and $2.5 million, respectively, as we determined the impairments to be other-than-temporary.

On September 8, 2011, a Consent Decree (the “Consent Decree”) settling environmental litigation and related claims involving Hecla Limited pertaining to historic releases of mining wastes in the Coeur d'Alene Basin was approved and entered by the U.S. District Court in Idaho. The Consent Decree resolved all existing claims of the Plaintiffs against Hecla Limited and its affiliates under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”) (and certain other statutes) for past response costs, future environmental remediation costs, and natural resource damages related to historic releases of mining wastes in the Coeur d'Alene River Basin. The Consent Decree also resolved all remaining obligations of Hecla Limited under the 1994 Consent Decree relating to the “Box,” a rectangular 21-square-mile site located near Kellogg, Idaho within the Bunker Hill Superfund site. The Consent Decree contains comprehensive terms of settlement, including financial terms which required that Hecla Limited pay, in the aggregate, $264.4 million to the Plaintiffs over approximately three years following the settlement. Payments of approximately $168 million, $25 million, and $15 million (and related interest) were made in October 2011, 2012, and 2013, respectively, pursuant to the terms of the Consent Decree. In addition, a payment of approximately $14.1 million in proceeds from warrants exercised during the second quarter of 2014 was made in July 2014. Finally, a payment of approximately $41.3 million, consisting primarily of proceeds from the exercise of the remaining outstanding warrants, was made in August 2014, which satisfied Hecla Limited's remaining payment obligations under the Consent Decree.

In June 2015, we completed the acquisition of Revett, giving us 100% ownership of the Troy mine and other interests in northwestern Montana (see Note 15 for more information). As a result, we recorded a $17.5 million liability for the present value of estimated costs for reclamation and closure of the Troy mine. Revett held an environmental risk transfer program ("insurance policy") which would have funded costs incurred prior to the expiration date of March 29, 2020 for reclamation at the Troy mine up to a maximum limit of $16.8 million. In the third quarter of 2016, we reached a settlement on the insurance policy for cash proceeds to us of $16.0 million.

On each of June 15, 2016 and September 19, 2016, a Consent Decree settling environmental claims involving our wholly-owned subsidiary, CoCa Mines, Inc. ("CoCa") at the Nelson Tunnel/Commodore Waste Rock Pile site (Colorado) and Gilt Edge site (South Dakota) was approved and entered by the U.S. District Court in Colorado and South Dakota, respectively. Pursuant to the Consent Decrees, CoCa paid an aggregate of $6 million in August 2016 to the United States and the State of Colorado, and an aggregate of $3.9 million in November 2016 to the United States and the State of South Dakota (insurers and another potentially responsible party ("PRP") paid an additional $6.4 million to settle the Gilt Edge matter). As a result, CoCa has resolved the claims with respect to the Gilt Edge and Nelson Tunnel sites. During the negotiations leading up to these settlements, in the second quarter of 2015 we accrued $9.9 million by recording a liability for the total amount that would be paid by CoCa to settle these matters, and an asset for the amount to be recovered by CoCa from insurers and the other settling PRP with respect to the Gilt Edge site.

Asset Retirement Obligations

Below is a reconciliation as of December 31, 2016 and 2015 (in thousands) of the asset retirement obligations ("ARO") relating to our operating properties, which are included in our total accrued reclamation and closure costs of $85.6 million and $95.5 million, respectively, discussed above. The estimated reclamation and abandonment costs were discounted using credit adjusted, risk-free interest rates ranging from 6% to 14.5% from the time we incurred the obligation to the time we expect to pay the retirement obligation.

|  | 2016 |  |  | 2015 |
Balance January 1 |  | $ | 53,233 |  |  | $ | 46,539 |
Changes in obligations due to changes in reclamation plans |  |  | 2,760 |  |  |  | 4,112 |

In the third quarter of 2016, we updated our ARO at Lucky Friday to reflect a reclamation plan that includes estimated costs for reclamation and closure of the mine and mill upon the end of the known mine life, in addition to reclamation of existing tailings impoundments already considered. The previous plan contemplated stabilization, clean-up and ongoing monitoring and maintenance of the mine and mill site. The change to the reclamation plan resulted in an increase in total undiscounted costs of approximately $22.6 million, and an increase to the ARO asset and liability of $3.3 million after discounting the costs to present value.

In the third quarter of 2016, we updated the ARO at San Sebastian to include estimated costs for filling the open pits at the end of their known life, resulting in an increase in undiscounted costs of $4.3 million and in increase in the ARO asset and liability of $4.5 million.

In the fourth quarter of 2016, we revised the ARO at Greens Creek to include costs for reclamation of additional waste rock, along with updated timing of estimated reclamation costs. The change resulted in an increase in undiscounted costs of $3.7 million, but a decrease in the ARO asset and liability of $5.0 million due to the impact of discounting costs to present value and the change in estimated timing costs.

The ARO layers related to the changes described above were discounted using a credit adjusted, risk-free interest rate of 6.5% and inflation rates ranging from 2% to 3.25%.

We evaluated the positive and negative evidence available to determine the amount of valuation allowance required on our deferred tax assets. At December 31, 2016 and 2015, the balances of our valuation allowances were approximately $100 million and $116 million, respectively, primarily related to net operating losses and tax credit carryforwards. The amount of the deferred tax asset considered recoverable, however, could be reduced in the near term if estimates of future taxable income are reduced.

At December 31, 2016 and 2015, the net deferred tax liability was approximately $87 million and $66 million, respectively. The individual components of our net deferred tax assets and liabilities are reflected in the table below (in thousands).

We plan to permanently reinvest earnings from foreign subsidiaries, with the exception of Hecla Quebec Inc., our wholly-owned subsidiary which owns our Casa Berardi mine and other interests in Quebec, Canada, and Minera Hecla, our wholly-owned subsidiary which owns our San Sebastian mine and other interests in Durango, Mexico. For the years 2016, 2015 and 2014, we had no unremitted foreign earnings. Foreign net operating losses carried forward are shown above as a deferred tax asset, with a partial valuation allowance as discussed below.

We recorded a valuation allowance to reflect the estimated amount of deferred tax assets, which may not be realized principally due to the forecasted expiration of net operating losses and tax credit carryforwards. A portion of the valuation allowance relating to foreign net operating loss carryforwards was released in 2015 as we determined that it was more likely than not that a portion of the benefit of the net operating loss carryforwards would be realized as a result of operating activities at San Sebastian. There was also significant utilization of deferred tax assets in the U.S. and Mexico. As of December 31, 2016, a $96 million valuation allowance remains in U.S. jurisdictions, $2 million in Hecla Canada Limited and $1 million in Minera Hecla S.A. de C.V. There is no valuation allowance at Hecla Quebec, Inc. The changes in the valuation allowance for the years ended December 31, 2016, 2015 and 2014, are as follows (in thousands):

As of December 31, 2016, for U.S. income tax purposes, we have federal and state net operating loss carryforwards of $244 million and $84 million, respectively. These net operating loss carryforwards have a 20 year expiration period, the earliest of which could expire in 2020. We have foreign and provincial net operating loss carryforwards of approximately $4 million each, which expire between 2017 and 2036. We have approximately $20 million in alternative minimum tax credit carryforwards which do not expire and are eligible to reduce future U.S. tax liabilities. Our utilization of U.S. net operating loss carryforwards may be subject to annual limitations if there is a change in control as defined under Internal Revenue Code Section 382.

Table of Contents

At December 31, 2016 and 2015 we had $22 million and $20 million, respectively, of federal net operating loss carryovers relating to excess tax benefits from the exercise of employee stock options and the vesting of restricted stock awards. These amounts are not reflected in our deferred tax asset for net operating loss carryovers. We recognize the excess tax benefits from the exercise of employee stock options and the vesting of restricted stock awards in the period in which these tax benefits reduce income taxes payable, after net operating loss carryforwards are fully utilized.

We file income tax returns in the U.S. federal jurisdiction, various state and foreign jurisdictions. We are no longer subject to income tax examinations by U.S. federal and state tax authorities for years prior to 2000, or examinations by foreign tax authorities for years prior to 2010. We currently have no tax years under examination.

We had no unrecognized tax benefits as of December 31, 2016 or 2015. Due to the net operating loss carryover provision, coupled with the lack of any unrecognized tax benefits, we have not provided for any interest or penalties associated with any uncertain tax positions. If interest and penalties were to be assessed, our policy is to charge interest to interest expense, and penalties to other operating expense. It is not anticipated that there will be any significant changes to unrecognized tax benefits within the next 12 months.

As discussed in Note 15, we acquired Mines Management, Inc. in September 2016. In accounting for this acquisition, we adopted a policy to consider the recoverability of deferred tax assets acquired in the acquisition before considering the recoverability of the acquirer’s existing deferred tax assets.

Note 6: Senior Notes, Credit Facilities and Capital Leases

Senior Notes

On April 12, 2013, we completed an offering of $500 million in aggregate principal amount of our Senior Notes due May 1, 2021 in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended, and in 2014, an additional $6.5 million aggregate principal amount of the Senior Notes was issued to one of our pension plans. The Senior Notes were subsequently exchanged for substantially identical Senior Notes registered with the SEC. The Senior Notes are governed by the Indenture, dated as of April 12, 2013, as amended (the "Indenture"), among Hecla Mining Company ("Hecla") and certain of our subsidiaries and The Bank of New York Mellon Trust Company, N.A., as trustee. The net proceeds from the initial offering of the Senior Notes ($490 million) were used to partially fund the acquisition of Aurizon and for general corporate purposes, including expenses related to the Aurizon acquisition.

The Senior Notes are recorded net of a 2% initial purchaser discount totaling $10 million at the time of the April 2013 issuance and having an unamortized balance of $5.5 million as of December 31, 2016. The Senior Notes bear interest at a rate of 6.875% per year from the date of original issuance or from the most recent payment date on which interest has been paid or provided for. Interest on the Senior Notes is payable on May 1 and November 1 of each year, commencing November 1, 2013. During 2016 and 2015, interest expense related to the Senior Notes and amortization of the initial purchaser discount and fees related to the issuance of the Senior Notes, net of $16.2 million and $13.5 million, respectively, in capitalized interest, totaled $20.1 million and $22.7 million, respectively.

The Senior Notes are guaranteed on a senior unsecured basis by certain of our subsidiaries (the "Guarantors"). The Senior Notes and the guarantees are, respectively, Hecla's and the Guarantors' general senior unsecured obligations and are subordinated to all of Hecla's and the Guarantors' existing and future secured debt to the extent of the assets securing that secured debt. In addition, the Senior Notes are effectively subordinated to all of the liabilities of Hecla's subsidiaries that are not guaranteeing the Senior Notes, to the extent of the assets of those subsidiaries.

The Senior Notes became redeemable in whole or in part, at any time and from time to time after May 1, 2016, on the redemption dates and at the redemption prices specified in the Indenture, plus accrued and unpaid interest, if any, to the date of redemption.

Upon the occurrence of a change of control (as defined in the Indenture), each holder of Senior Notes will have the right to require us to purchase all or a portion of such holder's Senior Notes pursuant to a change of control offer (as defined in the Indenture), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase, subject to the rights of holders of the Senior Notes on the relevant record date to receive interest due on the relevant interest payment date.

Credit Facility

In May 2016, we entered into a $100 million senior secured revolving credit facility with a three year term. The credit facility is collateralized by the shares of common stock held in our material domestic subsidiaries and by our joint venture interests in the Greens Creek mine, all of our rights and interests in the joint venture agreement, and all of our rights and interests in the assets of the joint venture. This credit facility replaced our previous $100 million credit facility which had the same terms of collateral as described above. Below is information on the interest rates, standby fee, and financial covenant terms under our current credit facility:

Interest rates: |  |  |  |  |
Spread over the London Interbank Offer Rate |  | 2.25 | - | 3.25% |
Spread over alternative base rate |  | 1.25 | - | 2.25% |
Standby fee per annum on undrawn amounts |  | 0.50% |
Covenant financial ratios: |  |  |  |  |
Senior leverage ratio (debt secured by liens/EBITDA) |  | not more than 2.50:1 |
Leverage ratio (total debt less unencumbered cash/EBITDA) |  | not more than 4.00:1 |
Interest coverage ratio (EBITDA/interest expense) |  | not more than 3.00:1 |

(1) The leverage ratio was amended to be 5.00:1 for 2016, and reverted back to 4.00:1 effective January 1, 2017.

We are also able to obtain letters of credit under the facility, and for any such letters we are required to pay a participation fee of between 2.25% and 3.25% based on our total leverage ratio, as well as a fronting fee to each issuing bank of 0.20% annually on the average daily dollar amount of any outstanding letters of credit. There were $2.6 million in letters of credit outstanding as of December 31, 2016.

We believe we were in compliance with all covenants under the credit agreement and no amounts were outstanding as of December 31, 2016. We have not drawn funds on the current revolving credit facility as of the filing date of this report.

Capital Leases

We have entered into various lease agreements, primarily for equipment at our Greens Creek, Lucky Friday and Casa Berardi units, which we have determined to be capital leases. At December 31, 2016, the total liability associated with the capital leases, including certain purchase option amounts, was $11.5 million, with $5.7 million of the liability classified as current and $5.8 million classified as non-current. At December 31, 2015, the total liability balance associated with capital leases was $17.6 million, with $8.7 million of the liability classified as current and $8.8 million classified as non-current. The total obligation for future minimum lease payments was $12.0 million at December 31, 2016, with $0.6 million attributed to interest.

Note 7: Commitments, Contingencies, and Obligations

General

We follow the FASB ASC guidance in determining our accruals and disclosures with respect to loss contingencies, and evaluate such accruals and contingencies for each reporting period. Accordingly, estimated losses from loss contingencies are accrued by a charge to income when information available prior to issuance of the financial statements indicates that it is probable that a liability could be incurred and the amount of the loss can be reasonably estimated. Legal expenses associated with the contingency are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred.

Rio Grande Silver Guaranty

Our wholly-owned subsidiary, Rio Grande Silver Inc. (“Rio”), is party to a joint venture with Emerald Mining & Leasing, LLC (“EML”) and certain other parties with respect to a land package in the Creede Mining District of Colorado that is adjacent to other land held by Rio. Rio holds a 70% interest in the joint venture. In connection with the joint venture, we are required to guarantee certain environmental remediation-related obligations of EML to a third party up to a maximum liability to us of $2.5 million. As of December 31, 2016, we have not been required to make any payments pursuant to the guaranty. We may be required to make payments in the future, limited to the $2.5 million maximum liability, should EML fail to meet its obligations to the third party. However, to the extent that any payments are made by us under the guaranty, EML, in addition to other parties, has jointly and severally agreed to reimburse and indemnify us for any such payments. We have not recorded a liability relating to the guaranty as of December 31, 2016.

Lucky Friday Water Permit Matters

Over the last several years the Lucky Friday unit has experienced several regulatory issues relating to its water discharge permits and water management more generally. In December 2013, the EPA issued to Hecla Limited a notice of violation (“2013 NOV”) alleging certain storm water reporting violations under Lucky Friday’s Clean Water Act Multi-Sector General Stormwater Permit for Industrial Activities. The alleged violations were resolved. The 2013 NOV also contained a request for information under Section 308 of the Clean Water Act directing Hecla Limited to undertake a comprehensive groundwater investigation of Lucky Friday’s tailings pond no. 3 to evaluate whether the pond is causing the discharge of pollutants via seepage to groundwater that is discharging to surface water.

We completed the investigation mandated by the EPA and submitted a draft report to the agency in December 2015. We are waiting for the EPA’s response, and until such time as the process is complete, we cannot predict what the impact of the investigation will be.

Hecla Limited strives to maintain its water discharges at the Lucky Friday unit in full compliance with its permits and applicable laws, however, we cannot provide assurance that in the future it will be able to fully comply with the permit limits and other regulatory requirements regarding water management.

Johnny M Mine Area near San Mateo, McKinley County, New Mexico

In May 2011, the EPA made a formal request to Hecla Mining Company for information regarding the Johnny M Mine Area near San Mateo, McKinley County, New Mexico, and asserted that Hecla Mining Company may be responsible under CERCLA for environmental remediation and past costs the EPA has incurred at the site. Mining at the Johnny M was conducted for a limited period of time by a predecessor of our subsidiary, Hecla Limited. In August 2012, Hecla Limited and the EPA entered into a Settlement Agreement and Administrative Order on Consent for Removal Action (“Consent Order”), pursuant to which Hecla Limited agreed to pay (i) $1.1 million to the EPA for its past response costs at the site and (ii) any future response costs at the site under the Consent Order, in exchange for a covenant not to sue by the EPA. Hecla Limited paid the approximately $1.1 million to the EPA for its past response costs and in December 2014, submitted to EPA the Engineering Evaluation and Cost Analysis (“EE/CA”) for the site. The EE/CA evaluates three alternative response actions: 1) no action, 2) off-site disposal, and 3) on-site disposal. The range in estimated costs of these alternatives is $0 to $221 million. In the EE/CA, Hecla Limited recommended that EPA approve on-site disposal, which is currently estimated to cost $5.6 million, on the basis that it is the most appropriate response action under CERCLA. In June 2015, the EPA approved the EE/CA, with a few minor conditions. The EPA still needs to publish the EE/CA for public notice and comment, and the agency will not make a final decision on the appropriate response action until the public comment process is complete. It is anticipated that Hecla Limited will implement the response action selected by the EPA pursuant to an amendment to the Consent Order or a new order. Based on the foregoing, we believe it is probable that Hecla Limited will incur a liability for remediation at the site, and our best estimate of that liability as of the date of this report is $5.6 million, and we have accrued that amount. There can be no assurance that Hecla Limited’s liability will not be more than $5.6 million, or that its ultimate liability will not have a material adverse effect on Hecla Limited’s or our results of operations or financial position.

In September 2016, Hecla Limited was served with a lawsuit filed by an individual in state court in New Mexico alleging personal injury claims of several millions of dollars arising from alleged exposure to contaminants as a result of allegedly living on land adjacent to the Johnny M Mine site. The case was subsequently removed to federal court in New Mexico, and Hecla Limited filed a motion to dismiss. We do not yet have enough information to conclude if Hecla Limited has any liability or to estimate any loss that it may incur.

Carpenter Snow Creek Site, Cascade County, Montana

In July 2010, the EPA made a formal request to Hecla Mining Company for information regarding the Carpenter Snow Creek Superfund Site located in Cascade County, Montana. The Carpenter Snow Creek Site is located in a historic mining district, and in the early 1980s Hecla Limited leased 6 mining claims and performed limited exploration activities at the site. Hecla Limited terminated the mining lease in 1988.

F-25

Table of Contents

In June 2011, the EPA informed Hecla Limited that it believes Hecla Limited, among several other viable companies, may be liable for cleanup of the site or for costs incurred by the EPA in cleaning up the site. The EPA stated in the June 2011 letter that it has incurred approximately $4.5 million in response costs and estimated that total remediation costs may exceed $100 million. Hecla Limited cannot with reasonable certainty estimate the amount or range of liability, if any, relating to this matter because of, among other reasons, the lack of information concerning the site.

Senior Notes

On April 12, 2013, we completed an offering of $500 million aggregate principal amount of 6.875% Senior Notes due 2021. The net proceeds from the offering of the Senior Notes were used to partially fund the acquisition of Aurizon Mines Ltd. ("Aurizon") and for general corporate purposes, including expenses related to the Aurizon acquisition. Aurizon held our Casa Berardi mine and other interests in Quebec, Canada. In 2014, we completed additional issuances of our Senior Notes in the aggregate principal amount of $6.5 million, which were contributed to one of our pension plans to satisfy the funding requirement for 2014. Interest on the Senior Notes is payable on May 1 and November 1 of each year, commencing November 1, 2013. See Note 6 for more information.

Other Commitments

Our contractual obligations as of December 31, 2016 included approximately $0.4 million for various costs. In addition, our open purchase orders at December 31, 2016 included approximately $0.7 million, $2.1 million and $10.0 million, respectively, for various capital and non-capital items at the Lucky Friday, Casa Berardi and Greens Creek units. We also have total commitments of approximately $12.0 million relating to scheduled payments on capital leases, including interest, primarily for equipment at our Greens Creek, Lucky Friday and Casa Berardi units (see Note 6 for more information). As part of our ongoing business and operations, we are required to provide surety bonds, bank letters of credit, and restricted deposits for various purposes, including financial support for environmental reclamation obligations and workers compensation programs. As of December 31, 2016, we had surety bonds totaling $112.7 million in place as financial support for future reclamation and closure costs, self-insurance, and employee benefit plans. The obligations associated with these instruments are generally related to performance requirements that we address through ongoing operations. As the requirements are met, the beneficiary of the associated instruments cancels or returns the instrument to the issuing entity. Certain of these instruments are associated with operating sites with long-lived assets and will remain outstanding until closure of the sites. We believe we are in compliance with all applicable bonding requirements and will be able to satisfy future bonding requirements as they arise.

Other Contingencies

On April 12, 2013, the family of Larry Marek, an employee of Hecla Limited who was fatally injured in an April 2011 accident, filed a lawsuit against us and certain of our officers and employees in state court in Idaho (Kootenai County District Court) seeking damages for, among other claims, wrongful death and infliction of emotional distress. On April 21, 2015, the judge hearing the case granted Hecla’s motion for summary judgment and dismissed the case. The plaintiffs appealed the decision to the Idaho Supreme Court, which affirmed the lower court’s decision on November 18, 2016, ending the lawsuit.

On December 11, 2013, four employees of Hecla Limited who were injured in a December 2011 rock burst filed a lawsuit against us and certain of our employees in state court in Idaho (Kootenai County District Court) seeking damages for, among other claims, intentional and willful injury and infliction of emotional distress. On August 28, 2015, the judge hearing the case granted Hecla’s motion for summary judgment and dismissed the case. The plaintiffs appealed the decision to the Idaho Supreme Court, which affirmed the lower court’s decision on November 18, 2016, ending the lawsuit.

When we acquired Revett Mining Company, Inc. in June 2015 (now known as Hecla Montana, Inc.), it was the subject of a lawsuit filed in Montana state court by an employee of its wholly owned subsidiary, Troy Mine, Inc., alleging that Revett was responsible for injuries he suffered on the job. The case is continuing with plaintiff claiming injuries totaling several millions of dollars; however, we believe the claims are without merit and that the injured employee is limited under Montana law to recovery under workers’ compensation insurance. Although it is possible that Revett faces some liability in the case, we are unable to estimate the amount or range of any potential liability. Insurance is currently providing a defense to Revett, however there is no guarantee it would provide coverage for any losses incurred.

F-26

Table of Contents

We also have certain other contingencies resulting from litigation, claims, EPA investigations, and other commitments and are subject to a variety of environmental and safety laws and regulations incident to the ordinary course of business. We currently expect that the resolution of such contingencies will not materially affect our financial position, results of operations or cash flows. However, in the future, there may be changes to these contingencies, or additional contingencies may occur, any of which might result in an accrual or a change in the estimated accruals recorded by us, and there can be no assurance that their ultimate disposition will not have a material adverse effect on our financial position, results of operations or cash flows.

The benefit obligation and prepaid benefit costs were calculated by applying the following weighted average assumptions:

|  | Pension Benefits |
|  | 2016 |  |  | 2015 |
Discount rate: net periodic pension cost |  |  | 4.45 | % |  |  | 4.17 | %
Discount rate: projected benefit obligation |  |  | 4.14 | % |  |  | 4.45 | %
Expected rate of return on plan assets |  |  | 6.80 | % |  |  | 7.20 | %
Rate of compensation increase: net periodic pension cost |  |  | 2.00 | % |  |  | 2.00 | %
Rate of compensation increase: projected benefit obligation (1) |  | 0.00%/2.00 | % |  | 0.00%/2.00 | %

(1) 0% was assumed for years 2016 through 2018 and 2% was assumed thereafter.

The above assumptions were calculated based on information as of December 31, 2016 and December 31, 2015, the measurement dates for the plans. The discount rate is based on the yield curve for investment-grade corporate bonds as published by the U.S. Treasury Department. The expected rate of return on plan assets is based upon consideration of the plan’s current asset mix, historical long-term return rates and the plan’s historical performance. Our current expected rate on plan assets of 6.8% is based on historical returns over the past five years.

Net periodic pension cost for the plans consisted of the following in 2016, 2015, and 2014 (in thousands):

|  | Pension Benefits |
|  | 2016 |  |  | 2015 |  |  | 2014 |

"Company stock" asset category in the table above includes our common stock in the amounts of $6.3 million and $4.3 million at December 31, 2016 and December 31, 2015.

Each plan's statement of investment policy delineates the responsibilities of the board, the retirement/pension committee, the investment manager(s), and investment adviser/consultant, and provides guidelines on investment management. Investment objectives are established for each of the asset categories included in the pension plans with comparisons of performance against appropriate benchmarks. Each plan's policy calls for investments to be supervised by qualified investment managers. The investment managers are monitored on an ongoing basis by our outside consultant, with formal reporting to us and the consultant performed each quarter. The policy sets forth the following allocation of assets:

Each plan's statement of investment policy and objectives aspires to achieve the assumed long term rate of return on plan assets established by the plan’s actuary plus one percent.

Accounting guidance has established a hierarchy of assets measured at fair value on a recurring basis. The three levels included in the hierarchy are:

Level 1: quoted prices in active markets for identical assets or liabilities

Level 2: significant other observable inputs

Level 3: significant unobservable inputs

Generally, investments are valued based on information provided by fund managers to each plan's trustee as reviewed by management and its investment advisers. Mutual funds and equities are valued based on available exchange data. Commingled equity funds consist of publicly-traded investments. Fair value for real estate and private equity partnerships is primarily based on valuation methodologies that include third-party appraisals, comparable transactions, and discounted cash flow valuation models.

Capital Accumulation Plans

Our Capital Accumulation Plan ("Hecla 401(k) Plan") is available to all U.S. salaried and certain hourly employees and applies immediately upon employment. Employees may contribute from 1% to 50% of their annual compensation to the plan (subject to statutory limits). We make a matching contribution in the form of cash or stock of 100% of an employee’s contribution up to 6% of the employee’s earnings. Our matching contributions were approximately $3.5 million in 2016, $3.4 million in 2015, and $3.2 million in 2014.

Effective January 1, 2014, the Hecla 401(k) Plan was restated to allow for payment of matching contributions to be made in Hecla common stock on a quarterly basis. Prior to 2014, contributions were made in cash on a payroll-to-payroll basis.

We also maintain a 401(k) plan that is available to all hourly employees at the Lucky Friday unit after completion of six months of service. Employees may contribute from 2% to 50% of their compensation to the plan (subject to statutory limits). The matching contribution is 55% of an employee’s contribution up to, but not exceeding, 5% of the employee’s earnings. Our contributions were approximately $442,000 in 2016, $391,000 in 2015, and $292,000 in 2014.

Note 9: Stockholders’ Equity

Common Stock

We are authorized to issue 500,000,000 shares of common stock, $0.25 par value per share, of which 399,228,085 shares of common stock were issued as of December 31, 2016. All of our currently outstanding shares of common stock are listed on the New York Stock Exchange under the symbol “HL”.

Subject to the rights of the holders of any outstanding shares of preferred stock, each share of common stock is entitled to: (i) one vote on all matters presented to the stockholders, with no cumulative voting rights; (ii) receive such dividends as may be declared by the board of directors out of funds legally available therefor; and (iii) in the event of our liquidation or dissolution, share ratably in any distribution of our assets.

Dividends

In September 2011 and February 2012, 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 $0.01 per share of common stock, in each case, payable quarterly, when declared. For illustrative purposes only, the table below summarizes potential per share dividend amounts at different quarterly average realized price levels according to the first component of the policy:

Quarterly average realized silver price per ounce |  |  | Quarterly dividend per share |  |  | Annual dividend per share |

Because the average realized silver prices for all periods in 2014, 2015 and 2016 were below the minimum threshold of $30, according to the policy no silver-price-linked component was declared or paid. Prior to 2011, no dividends had been declared on our common stock since 1990. The declaration and payment of common stock dividends is at the sole discretion of our board of directors.

At-The-Market Equity Distribution Agreement

Pursuant to an equity distribution agreement dated February 23, 2016, we may issue and sell from time to time through ordinary broker transactions shares of our common stock having an aggregate offering price of up to $75 million, with the net proceeds available for general corporate purposes. The terms of sales transactions under the agreement, including trading day(s), number of shares sold in the aggregate, number of shares sold per trading day, and the floor selling price per share, are proposed by us to the sales agent. 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. The shares issued under the equity distribution agreement are registered under the Securities Act of 1933, as amended, pursuant to our shelf registration statement on Form S-3, which was filed with the SEC on February 23, 2016. As of December 31, 2016, we had sold 2,780,087 shares under the agreement for proceeds of approximately $8.1 million, net of commissions and fees of approximately $166 thousand.

Common Stock Repurchase Program

Under the program, we are authorized to repurchase up to 20 million shares of our outstanding common stock from time to time in open market or privately negotiated transactions, depending on prevailing market conditions and other factors. The repurchase program may be modified, suspended or discontinued by us at any time. As of December 31, 2016, 934,100 shares have been repurchased under the program, at an average price of $3.99 per share, leaving 19.1 million shares that may yet be purchased under the program.

The Series B preferred stock ranks senior to our common stock and any shares of Series A junior participating preferred stock (none of which have ever been issued) with respect to payment of dividends, and amounts due upon liquidation, dissolution or winding up.

While any shares of Series B preferred stock are outstanding, we may not authorize the creation or issuance of any class or series of stock that ranks senior to the Series B preferred stock as to dividends or amounts due upon liquidation, dissolution or winding up without the consent of the holders of 66 2/3% of the outstanding shares of Series B preferred stock and any other series of preferred stock ranking on a parity with the Series B preferred stock as to dividends and amounts due upon liquidation, dissolution or winding up, voting as a single class without regard to series.

Dividends

Series B preferred stockholders are entitled to receive, when, as and if declared by the board of directors out of our assets legally available therefor, cumulative cash dividends at the rate per annum of $3.50 per share of Series B preferred stock. Dividends on the Series B preferred stock are payable quarterly in arrears on October 1, January 1, April 1 and July 1 of each year (and, in the case of any undeclared and unpaid dividends, at such additional times and for such interim periods, if any, as determined by the board of directors), at such annual rate. Dividends are cumulative from the date of the original issuance of the Series B preferred stock, whether or not in any dividend period or periods we have assets legally available for the payment of such dividends. Accumulations of dividends on shares of Series B preferred stock do not bear interest.

All quarterly dividends on our Series B preferred stock for 2014, 2015 and 2016 were declared and paid in cash.

Redemption

The Series B preferred stock is redeemable at our option, in whole or in part, at $50 per share, plus all dividends undeclared and unpaid on the Series B preferred stock up to the date fixed for redemption.

Liquidation Preference

The Series B preferred stockholders are entitled to receive, in the event that we are liquidated, dissolved or wound up, whether voluntary or involuntary, $50 per share of Series B preferred stock plus an amount per share equal to all dividends undeclared and unpaid thereon to the date of final distribution to such holders (the “Liquidation Preference”), and no more. Until the Series B preferred stockholders have been paid the Liquidation Preference in full, no payment will be made to any holder of Junior Stock upon our liquidation, dissolution or winding up. The term “junior stock” means our common stock and any other class of our capital stock issued and outstanding that ranks junior as to the payment of dividends or amounts payable upon liquidation, dissolution and winding up to the Series B preferred stock. As of December 31, 2016 and 2015, our Series B preferred stock had a Liquidation Preference of $7.9 million.

Voting Rights

Except in certain circumstances and as otherwise from time to time required by applicable law, the Series B preferred stockholders have no voting rights and their consent is not required for taking any corporate action. When and if the Series B preferred stockholders are entitled to vote, each holder will be entitled to one vote per share.

Conversion

Each share of Series B preferred stock is convertible, in whole or in part at the option of the holders thereof, into shares of common stock at a conversion price of $15.55 per share of common stock (equivalent to a conversion rate of 3.2154 shares of common stock for each share of Series B preferred stock). The right to convert shares of Series B preferred stock called for redemption will terminate at the close of business on the day preceding a redemption date (unless we default in payment of the redemption price).

Stock Award Plans

We use stock-based compensation plans to aid us in attracting, retaining and motivating our employees, as well as to provide us with the ability to provide incentives more directly linked to increases in stockholder value. These plans provide for the grant of options to purchase shares of our common stock, the issuance of restricted stock units, and other equity-based awards.

Stock-based compensation expense amounts recognized for the years ended December 31, 2016, 2015 and 2014 were approximately $6.2 million, $5.4 million, and $5.0 million, respectively. Over the next twelve months, we expect to recognize approximately $3.2 million in additional compensation expense as outstanding restricted stock units vest.

Stock Incentive Plan

During the second quarter of 2010, our stockholders voted to approve the adoption of our 2010 Stock Incentive Plan and to reserve up to 20,000,000 shares of common stock for issuance under the plan. The board of directors has broad authority under the 2010 plan to fix the terms and conditions of individual agreements with participants, including the duration of the award and any vesting requirements. As of December 31, 2016, there were 8,302,326 shares available for future grant under the 2010 plan.

Directors’ Stock Plan

In 1995, we adopted the Hecla Mining Company Stock Plan for non-employee directors (the “Directors’ Stock Plan”), which may be terminated by our board of directors at any time. Each non-employee director is credited on May 30 of each year with that number of shares determined by dividing $24,000 by the average closing price for our common stock on the New York Stock Exchange for the prior calendar year. All credited shares are held in trust for the benefit of each director until delivered to the director. Delivery of the shares from the trust occurs upon the earliest of: (1) death or disability; (2) retirement; (3) a cessation of the director’s service for any other reason; or (4) a change in control. The shares of our common stock credited to non-employee directors pursuant to the Directors’ Stock Plan may not be sold until at least six months following the date they are delivered. A maximum of one million shares of common stock may be granted pursuant to the Directors’ Stock Plan. During 2016, 2015, and 2014, 68,462, 48,244, and 39,468 shares, respectively, were credited to the non-employee directors. During 2016, 2015 and 2014, $271,000, $150,000, and $109,000, respectively, was charged to general and administrative expense associated with the Directors’ Stock Plan. At December 31, 2016, there were 438,459 shares available for grant in the future under the plan.

In addition to the foregoing, in May of each year, each non-employee director is also granted additional common stock under our 2010 Stock Incentive Plan. For 2016, 2015, and 2014, 120,911, 186,888, and 110,910 shares, respectively, were credited to the non-employee directors, and $532,000, $456,000, and $366,000 respectively, was charged to operations associated with the 2010 Stock Incentive Plan.

Restricted Stock Units

Unvested restricted stock units granted by the board of directors to employees are summarized as follows:

|  | Shares |  |  | Weighted Average Grant Date Fair Value per Share |
Unvested, January 1, 2016 |  |  | 3,375,798 |  |  | $ | 2.73 |
Granted (unvested) |  |  | 1,138,669 |  |  | $ | 4.40 |
Canceled |  |  | (205,032 | ) |  | $ | 2.70 |
Distributed (vested) |  |  | (1,573,871 | ) |  | $ | 2.82 |
Unvested, December 31, 2016 |  |  | 2,735,564 |  |  | $ | 3.41 |

The 2,735,564 unvested units at December 31, 2016 are scheduled to vest as follows:

| 790,253 |  | in June 2017 |
| 650,137 |  | in July 2017 |
| 379,743 |  | in June 2018 |
| 579,437 |  | in July 2018 |
| 335,994 |  | in June 2019 |

Unvested units may be forfeited by participants through termination of employment in advance of vesting. Since the earliest grant date of unvested units (which was 2014), we have recognized approximately $4.8 million in compensation expense, including approximately $3.6 million recognized in 2016, and expect to record an additional $4.5 million in compensation expense over the remaining vesting period related to these units. The latest vesting date for unvested units as of December 31, 2016 is June 2019.

In connection with the vesting of restricted stock units and other stock grants, employees have in the past, at their election and when permitted by us, chosen to satisfy their tax withholding obligations through net share settlement, pursuant to which we withhold the number of shares necessary to satisfy such withholding obligations. Pursuant to such net settlements, in 2016 we repurchased 1,010,509 shares valued at approximately $3.5 million, or approximately $3.44 per share. In 2015, we withheld 613,698 shares valued at approximately $1.9 million, or approximately $3.05 per share. These shares become treasury shares unless we cancel them.

Note 10: Derivative Instruments

Foreign Currency

Our wholly-owned subsidiaries owning the Casa Berardi and San Sebastian mines are USD-functional entities which routinely incur expenses denominated in CAD and MXN, and such expenses expose us to exchange rate fluctuations between the USD and CAD and MXN. In April 2016, we initiated 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 October 2016, we also initiated a program to manage our exposure to the impact of fluctuations in the exchange rate between the USD and MXN on our future operating costs denominated in MXN. The programs utilize forward contracts to sell CAD and MXN, and each contract is designated as a cash flow hedge. As of December 31, 2016, we have 130 forward contracts outstanding to sell CAD$290.1 million having a notional amount of US$222.9 million, and 24 forward contracts outstanding to sell MXN$202.5 million having a notional amount of US$10.3 million. The CAD contracts represent between 21% and 75% of our annual forecasted cash operating costs at Casa Berardi from 2017 through 2020 and have CAD-to-USD exchange rates ranging between 1.2787 and 1.3380. The MXN contracts represent 75% of our forecasted cash operating costs at San Sebastian for 2017 and have MXN-to-USD exchange rates ranging between 18.9975 and 21.000. Our risk management policy allows for up to 75% of our planned cost exposure for five years into the future to be hedged under such programs, and for potential additional programs to manage other foreign currency-related exposure areas.

Table of Contents

As of December 31, 2016, we recorded the following balances for the fair value of the contracts:

• a non-current asset of $27 thousand, which is included in other non-current assets;

• a current liability of $2.8 million, which is included in other current liabilities, and

• a non-current liability of $2.4 million, which is included in other non-current liabilities.

Net unrealized losses of approximately $5.2 million related to the effective portion of the hedges were included in accumulated other comprehensive income as of December 31, 2016, and are net of related deferred taxes. 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 $3.0 million in net unrealized losses included in accumulated other comprehensive income as of December 31, 2016 would be reclassified to current earnings in the next twelve months. Net unrealized losses of approximately $2 thousand related to ineffectiveness of the hedges were included in gain (loss) on derivatives contracts on our consolidated statements of operations and comprehensive income (loss) for the year ended December 31, 2016.

Metals Prices

At times, we may 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 which 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 the market. 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 hedged under such programs. 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 currently use 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. These contracts are not designated as hedges and are marked-to-market through earnings each period. At December 31, 2016, we recorded a current asset of $2.8 million, which is included in other current assets and is net of $0.7 million for contracts in a fair value current liability position. In addition, we recorded a non-current asset of $2.5 million at December 31, 2016 which is included in other non-current assets.

We recognized a $14.2 million net loss during 2016 on the contracts utilized to manage exposure to prices of metals in our concentrate shipments, which is included in sales of products. The net loss recognized on the contracts offsets gains 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 $4.4 million net gain during 2016 on the contracts utilized to manage exposure to prices for forecasted future concentrate shipments. The net gain on these contracts is included as a separate line item under other income (expense), as they relate to forecasted future shipments, as opposed to sales that have already taken place but are subject to final pricing as discussed in the preceding paragraph. The net gain for 2016 is the result of decreasing zinc and lead prices. This program, when utilized, is designed to mitigate the impact of potential future declines in lead and zinc prices from the price levels established in the contracts (see average price information below).

Our concentrate sales are based on a provisional sales price containing an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of the concentrates at the forward price at the time of the sale. The embedded derivative, which does not qualify for hedge accounting, is adjusted to market through earnings each period prior to final settlement.

Credit-risk-related Contingent Features

We have agreements with certain counterparties that contain a provision whereby we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of December 31, 2016, we have not posted any collateral related to these agreements. The fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $6.4 million as of December 31, 2016. If we had breached any of these provisions at December 31, 2016, we could have been required to settle our obligations under the agreements at their termination value of $6.4 million.

Note 11: Business Segments and Significant Customers

We discover, acquire, develop, produce, and market concentrates and doré containing silver, gold, lead and zinc. Our products consist of both metal concentrates, which we sell to custom smelters and brokers, and unrefined bullion bars (doré), which may be sold as doré or further refined before sale to precious metals traders. We are currently organized and managed in four segments, which represent our operating units: the Greens Creek unit, the Lucky Friday unit, the Casa Berardi unit, and the San Sebastian unit. The San Sebastian unit, a historic operating property for Hecla, resumed commercial production in the fourth quarter of 2015 and was added as a new reporting segment in 2015.

General corporate activities not associated with operating units and their various exploration activities, as well as discontinued operations and idle properties, are presented as “other.” Interest expense, interest income and income taxes are considered general corporate items, and are not allocated to our segments.

The sales and income (loss) from operations amounts reported above include results from our Lucky Friday segment. The Lucky Friday mine is our only operation where some of our employees are subject to a collective bargaining agreement, and the most recent agreement expired on April 30, 2016. On February 19, 2017, the unionized employees voted against our contract offer. We expect further discussions with the union but it is possible that an agreement will not be reached, in which case we cannot predict what might happen next, including what actions we or the union might take in response to failing to reach an agreement. In the event of a prolonged strike or other event related to labor at the Lucky Friday, operations at Lucky Friday could be disrupted, which could adversely affect our financial condition and results of operations.

Note 12: Fair Value Measurement

The table below sets forth our assets and liabilities (in thousands) that were accounted for at fair value on a recurring basis and the fair value calculation input hierarchy level that we have determined applies to each asset and liability category. See Note 8 for information on the fair values of our defined benefit pension plan assets.

Cash and cash equivalents consist primarily of money market funds and are valued at cost, which approximates fair value, and a small portion consists of municipal bonds having maturities of less than 90 days, which are recorded at fair value.

Current available-for-sale securities consist of municipal and corporate bonds having maturities of more than 90 days, which are recorded at fair value.

Current and non-current restricted cash balances consist primarily of certificates of deposit, U.S. Treasury securities, and other deposits and are valued at cost, which approximates fair value.

Our non-current available for sale securities consist of marketable equity securities of companies in the mining industry which are valued using quoted market prices for each security.

Trade accounts receivable include amounts due to us for shipments of concentrates, doré and precipitate sold to customers. Revenues and the corresponding accounts receivable for sales of metals products are recorded when title and risk of loss transfer to the customer (generally at the time of loading on truck or ship). Sales of concentrates are recorded using estimated forward prices for the anticipated month of settlement applied to our estimate of payable metal quantities contained in each shipment. Sales are recorded net of estimated treatment and refining charges, which are also impacted by changes in metals prices and quantities of contained metals. We estimate the prices at which sales of our concentrates will be settled due to the time elapsed between shipment and final settlement with the customer. Receivables for previously recorded concentrate sales are adjusted to reflect estimated forward metals prices at the end of each period until final settlement by the customer. We obtain the forward metals prices used each period from a pricing service. Changes in metal prices between shipment and final settlement result in changes to revenues previously recorded upon shipment. The embedded derivative contained in our concentrate sales is adjusted to fair market value through earnings each period prior to final settlement.

We use financially-settled forward contracts to manage exposure to changes in the exchange rate between the U.S. dollar and Canadian dollar and Mexican peso, and the impact on Canadian dollar- and Mexican peso-denominated operating costs incurred at our Casa Berardi and San Sebastian units (see Note 10 for more information). These contracts qualify for hedge accounting, with unrealized gains and losses related to the effective portion of the contracts included in accumulated other comprehensive loss, and unrealized gains and losses related to the ineffective portion of the contracts included in earnings each period. The fair value of each contract represents the present value of the difference between the forward exchange rate for the contract settlement period as of the measurement date and the contract settlement exchange rate.

We use financially-settled forward contracts to manage the exposure to changes in prices of silver, gold, zinc and lead contained in our concentrate shipments that have not reached final settlement. We also use financially-settled forward contracts to manage the exposure to changes in prices of zinc and lead contained in our forecasted future concentrate shipments (see Note 10 for more information). These contracts do not qualify for hedge accounting, and are marked-to-market through earnings each period. The fair value of each contract represents the present value of the difference between the forward metal price for the contract settlement period as of the measurement date and the contract settlement metal price.

Our Senior Notes, which were recorded at their carrying value of $501.0 million, net of unamortized initial purchaser discount at December 31, 2016, had a fair value of $521.4 million at December 31, 2016. Third-party quotes, which we consider to be Level 2 inputs, are utilized to estimate fair values of the Senior Notes. See Note 6 for more information.

Note 13: Income (Loss) per Common Share

We are authorized to issue 500,000,000 shares of common stock, $0.25 par value per share. At December 31, 2016, there were 399,228,085 shares of our common stock issued and 3,941,210 shares issued and held in treasury, for a net of 395,286,875 shares outstanding.

We calculate basic earnings per share using, as the denominator, the weighted average number of common shares outstanding during the period. Diluted earnings per share uses, as its denominator, the weighted average number of common shares outstanding during the period plus the effect of potential dilutive common shares during the period using the treasury stock method for options, warrants, and restricted stock units, and if-converted method for convertible preferred shares.

Potential dilutive common shares include outstanding stock options, restricted stock unit awards, stock units, warrants and convertible preferred stock for periods in which we have reported net income. For periods in which we reported net losses, potential dilutive common shares are excluded, as their conversion and exercise would not reduce earnings per share. Under the if-converted method, preferred shares would not dilute earnings per share in any of the periods presented.

A total of 157,816 shares of preferred stock were outstanding at December 31, 2016, 2015 and 2014.

There were no outstanding options for the years ended December 31, 2016 and 2015. For the year ended December 31, 2014, options to purchase 259,342 shares of our common stock were excluded from the computation of diluted earnings per share, as the exercise price of the options exceeded the average price of our stock during those periods and therefore would not affect the calculation of earnings per share. For the years ended December 31, 2016 and 2014, respectively, 4,309,440 and 4,670,170 restricted stock units that were unvested or vested during the year were included in the calculation of diluted earnings per share. For the year ended December 31, 2015, all outstanding restricted stock units and warrants were excluded from the computation of diluted loss per share, as our reported net losses for that period would cause their conversion and exercise to have no effect on the calculation of loss per share.

Note 15: Acquisitions

Acquisition of Mines Management

On September 13, 2016, we completed the acquisition of Mines Management and its subsidiaries through the merger of a wholly owned subsidiary of ours with and into Mines Management, pursuant to which we acquired all of the issued and outstanding common stock of Mines Management for total consideration of $52.1 million. The acquired entities hold 100% ownership of the Montanore project in Northwest Montana, a significant undeveloped silver and copper deposit which we believe provides long-term production growth potential if permitted and developed. Montanore is approximately 10 miles away from our Rock Creek project acquired through our acquisition of Revett Mining Company, Inc. in June 2015. The consideration was comprised of $4.0 million in cash used to fund Mines Management's operating activities prior to completion of the merger and for settlement of outstanding warrants to purchase shares of Mines Management's common stock, and $48.1 million in Hecla common stock. In the merger, each outstanding common share of Mines Management was exchanged for 0.2218 of a share of our common stock. Mines Management had 36,498,625 outstanding common shares and outstanding options to purchase 963,079 shares of Mines Management common stock, resulting in 8,309,006 new shares of Hecla stock issued as consideration. The value of Hecla stock issued as consideration was based upon the closing price at the time of consummation of $5.79 per share.

The $68.0 million fair value for "Property, plants, equipment, and mineral interests" is comprised of $0.8 million for plant and equipment, $0.1 million for land, and $67.1 million for mineral interests.

The allocation of purchase price above is considered preliminary, as review by management of the valuation methodologies for mineral interests and the related deferred tax liability has not been finalized.

In September 2016, we issued 181,048 shares of our common stock for payment of approximately $1.0 million in acquisition-related costs, which are included in Acquisition costs on our Consolidated Statements of Operations and Comprehensive Income (Loss).

The unaudited pro forma financial information below represents the combined results of our operations as if the acquisition had occurred at the beginning of the periods presented.

Takeover Bid for Dolly Varden Silver Corporation

On June 27, 2016, we announced a takeover bid for all of the outstanding shares of Dolly Varden Silver Corporation ("Dolly Varden") not owned by us and our affiliates for cash of CAD$0.69 per share. Dolly Varden owns 100% of the Dolly Varden historic silver property in northwestern British Columbia, Canada. Our wholly owned subsidiary owns 4,478,087 Dolly Varden shares and warrants to purchase 1,351,762 Dolly Varden shares, representing approximately 18.5% of Dolly Varden's shares outstanding on a partially diluted basis. Based on Dolly Varden's outstanding shares and options and warrants to acquire Dolly Varden shares, and excluding shares and warrants held by us and our affiliates, total consideration would have been approximately CAD$13.6 million. In late July 2016, we withdrew the bid due to the failure of a required condition precedent to its consummation.

Acquisition of Revett Mining Company, Inc.

On June 15, 2015, we completed the acquisition of Revett through the merger of a wholly owned subsidiary of ours with and into Revett, pursuant to which we acquired all of the issued and outstanding common stock of Revett for total consideration of $20.1 million. The acquired entities hold 100% ownership of two properties and other interests in north-west Montana, including: the Troy Mine, which is on care-and-maintenance and which we intend to reclaim and close, and the Rock Creek project, a significant undeveloped silver and copper deposit which we believe provides long-term production growth potential if permitted and developed. The consideration was comprised of $0.9 million in cash used to fund Revett's operating activities prior to completion of the merger and $19.1 million in Hecla common stock. In the merger, each outstanding common share of Revett was exchanged for 0.1622 of a share of our common stock. Revett had 38,548,989 outstanding common shares, excluding 725,000 shares owned by our wholly-owned subsidiary which were canceled in the merger, resulting in 6,252,646 new shares of Hecla stock issued as consideration. The value of Hecla stock issued as consideration was based upon the closing price at the time of consummation of $3.06 per share.

The $17.6 million fair value for "Property, plants, equipment, and mineral interests" is comprised of $4.1 million for plant and equipment, $4.6 million for land, and $8.9 million for mineral interests.

The $17.5 million value for "Non-current reclamation liability" represents the present value of estimated costs for reclamation and closure of the Troy mine. Revett held an environmental risk transfer program ("insurance policy") which would have funded costs incurred prior to the expiration date of March 29, 2020 for reclamation at the Troy mine up to a maximum limit of $16.8 million. We therefore included the $16.8 million "Reclamation insurance" asset above for the fair value of the insurance policy at the time of acquisition. However, in the third quarter of 2016, we reached a settlement on the insurance policy for cash proceeds to us of $16.0 million. The $0.7 million difference between the settlement amount and the asset balance prior to settlement was recorded to expense.

The unaudited pro forma financial information includes adjustments to 1) eliminate acquisition-related costs totaling $2.4 million for the year ended December 31, 2015 which are non-recurring and 2) reflect the issuance of Hecla stock as consideration in the acquisition. A net loss by the acquired entities since the acquisition date of $1.7 million is included in our net loss reported for the year ended December 31, 2015.

Revett’s consolidated statement of operations and comprehensive income for the year ended December 31, 2014 included a $54.7 million expense for impairment of property, plant and equipment. Revett recognized the impairment as of December 31, 2014, with the estimated fair value of long-lived assets based on the merger agreement between Hecla and Revett. The impairment is not eliminated through an adjustment to the unaudited pro forma condensed combined statement of operations. However, it is a nonrecurring item and is not reflective of the operating results for the combined entities after consummation of the merger.

Note 16: Guarantor 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 (the "Guarantors") of the Senior Notes (see Note 6 for more information). The Guarantors consist of the following of Hecla's 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 Corp.; Montanore Minerals Corp.; Hecla Alaska LLC; Hecla Greens Creek Mining Company; Hecla Admiralty Company; and Hecla Juneau Mining Company. We completed the initial offering of the Senior Notes on April 12, 2013, and a related exchange offer for virtually identical notes registered with the SEC on January 3, 2014.

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 intercompany 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:

| • | Investments in subsidiaries. The acquisition of a company results in an investment in debt or equity capital on the records of the parent company and a contribution to debt or equity capital on the records of the subsidiary. Such investments and capital contributions are eliminated in consolidation.

| • | Capital contributions. Certain of Hecla's subsidiaries do not generate cash flow, either at all or sufficient to meet their capital needs, and their cash requirements are routinely met with inter-company advances from their parent companies. On an annual basis, when not otherwise intended as debt, the boards of directors of such parent companies declare contributions of capital to their subsidiary companies, which increase the parents' investment and the subsidiaries' additional paid-in capital. In consolidation, investments in subsidiaries and related additional paid-in capital are eliminated.

| • | Debt. Inter-company debt agreements have been established between certain of Hecla's subsidiaries and their parents. The related debt liability and receivable balances, accrued interest expense (if any) and income activity (if any), and payments of principal and accrued interest amounts (if any) by the subsidiary companies to their parents are eliminated in consolidation.

| • | Dividends. Certain of Hecla's subsidiaries which generate cash flow routinely provide cash to their parent companies through inter-company transfers. On an annual basis, the boards of directors of such subsidiary companies declare dividends to their parent companies, which reduces the subsidiaries' retained earnings and increases the parents' dividend income. In consolidation, such activity is eliminated.

| • | Deferred taxes. Our ability to realize deferred tax assets and liabilities is considered on a consolidated basis for subsidiaries within the United States, with all subsidiaries' estimated future taxable income contributing to the ability to realize all such assets and liabilities. However, when Hecla's subsidiaries are viewed independently, we use the separate return method to assess the realizability of each subsidiary's deferred tax assets and whether a valuation allowance is required against such deferred tax assets. In some instances, a parent company or subsidiary may possess deferred tax assets whose realization depends on the future taxable incomes of other subsidiaries on a consolidated-return basis, but would not be considered realizable if such parent or subsidiary filed on a separate stand-alone basis. In such a situation, a valuation allowance is assessed on that subsidiary's deferred tax assets, with the resulting adjustment reported in the eliminations column of the guarantor and parent's financial statements, as is the case in the financial statements set forth below. The separate return method can result in significant eliminations of deferred tax assets and liabilities and related income tax provisions and benefits. Non-current deferred tax asset balances are included in other non-current assets on the consolidating balance sheets and make up a large portion of that item, particularly for the guarantor balances.

Table of Contents

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.

Effective December 31, 2015, Hecla Limited (our wholly owned subsidiary) sold 100% of its ownership of Hecla Alaska LLC (its wholly owned subsidiary) to Hecla Mining Company for consideration totaling approximately $240.8 million.
