Item 1.01 – Entry into a Material Definitive Agreement

On July 4, 2022, Hecla Mining Company (the “Company” or “Hecla”) entered into an Arrangement Agreement (the “Alexco Agreement”) with Alexco Resources Corp. (“Alexco”). Under the terms of the Alexco Agreement, Hecla will acquire all of the outstanding shares of Alexco, and Alexco’s shareholders will receive 0.116 of a share of Hecla common stock per Alexco share, representing total consideration with a value of US$0.47 per Alexco share (based on the companies’ 5-day volume weighted average price on the New York Stock Exchange (“NYSE”) and NYSE American on July 1, 2022). As part of the Alexco Agreement, Hecla has agreed to:

• provide a loan to Alexco in the amount of up to $30 million to bridge Alexco’s operations from signing to closing; and

• subscribe for and purchase 8,984,100 Alexco common shares at CDN$0.50 per share, having an aggregate value of US$3,593,640. Following such purchase, Hecla and its affiliates will own 9.9% of the outstanding Alexco shares.

The Alexco Agreement is attached hereto as Exhibit 2.1, and is incorporated herein by reference.

Concurrently with entering into the Alexco Agreement, the Company entered into a Stream Termination Agreement (the “WPM Agreement” and together with the Alexco Agreement, the “Agreements”) with Wheaton Precious Metals Corp. (“WPM”). Under the WPM Agreement, after the closing of the Alexco acquisition, the Company will issue shares of its common stock valued at US$135 million based on Hecla’s 5-day volume-weighted average price immediately prior to the closing in exchange for the termination of WPM’s silver streaming interest in Alexco’s Keno Hill silver mine located in the Yukon Territory, Canada.

The Alexco Agreement has been incorporated by reference herein to provide you with information regarding its terms. It is not intended to provide any other factual information about us. Such information can be found elsewhere in other public filings we have made with the Securities and Exchange Commission, which are available without charge at www.sec.gov.

The Agreements contain representations and warranties the Company, Alexco and WPM made. The assertions embodied in the Alexco representations and warranties are qualified by information in a confidential disclosure letter that Alexco has exchanged in connection with signing the Alexco Agreement. While the Company does not believe that it contains information securities laws require us to publicly disclose other than information that has already been so disclosed, the disclosure letter does contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Agreement. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts, since they are modified in important part by the disclosure letter. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the Alexco Agreement, which subsequent information may or may not be fully reflected in public disclosures.

The information disclosed under Item 8.01 is incorporated herein by reference.

Item 3.02 – Unregistered Sales of Equity Securities

The description of the consideration to be received by Alexco shareholders set forth in Item 1.01 above is incorporated herein by reference. The shares of common stock of Hecla to be issued under the Alexco Agreement will be issued pursuant to an exemption from registration under Section 3(a)(10) of the Securities Act of 1933. The Company anticipates that the exemption will be available because the Agreement provides that the transactions contemplated by the Agreement will be implemented by way of a court-approved plan of arrangement. Exhibit 2.1 attached hereto is incorporated herein by reference.

The description of the consideration to be received by WPM set forth in Item 1.01 above is incorporated herein by reference. The shares of common stock of Hecla to be issued under the WPM Agreement will be issued pursuant to an exemption from registration under Section 4(2) of the Securities Act of 1933. The Company anticipates that the exemption will be available because in the WPM Agreement, WPM represents to Hecla that it is an accredited investor as that term is defined under the Securities Act of 1933, and WPM has acknowledged and agreed that the shares of Hecla common stock it would receive upon the closing of the transaction will be restricted for a minimum of 6 months from the date of issuance.

Item 8.01 Other Events

On July 5, 2022, the Company issued a news release with respect to the Agreements. A copy of the news release is attached hereto as Exhibit 99.1, and is incorporated herein by reference. As announced in the release, the Company and Alexco will hold a conference call to discuss the transaction at 8:30 a.m. (Eastern Time) on July 5, 2022. A slide presentation that will be made in connection with the conference call is attached hereto as Exhibit 99.2 to this Form 8-K, and is incorporated herein by reference.

(b) Alexco has been, and continues to be, in compliance with its obligations under this Section 7.2 in all material respects;

(c) Alexco or its Representatives have delivered to Hecla the information required by Section 7.2.4 and a written notice of the determination of Alexco Board that such Acquisition Proposal constitutes a Superior Proposal and of the intention of Alexco Board to make Alexco Change in Recommendation and/or terminate this Agreement pursuant to Section 8.2.1(d)(i) to concurrently enter into Alexco Proposed Agreement with respect to such Superior Proposal, as applicable, together with a written notice from the Alexco Board regarding the value that the Alexco Board, in consultation with an Alexco Financial Advisor, has determined should be ascribed to any non-cash consideration offered under such Acquisition Proposal (collectively, the “Superior Proposal Notice”);

(d) in the case of Alexco Board exercising its rights under clause (2) of this Section 7.2.7, Alexco or its Representatives have provided Hecla a copy of Alexco Proposed Agreement and all supporting materials, including any financing documents with customary redactions supplied to Alexco in connection therewith;

(e) five Business Days (the “Hecla Response Period”) shall have elapsed from the date on which Hecla has received Superior Proposal Notice and all documentation referred to in Section 7.2.7(c) and Section 7.2.7(d);

(f) during any Hecla Response Period, Hecla has had the opportunity (but not the obligation) in accordance with Section 7.2.8, to offer to amend this Agreement and the Plan of Arrangement in order for such Acquisition Proposal to cease to be a Superior Proposal;

(g) after the Hecla Response Period, the Alexco Board (A) has determined in good faith, after consultation with its outside legal counsel and financial advisors, that such Acquisition Proposal continues to constitute a Superior Proposal (if applicable, compared to the terms of the Arrangement as proposed to be amended by Hecla under Section 7.2.8) and (B) has determined in good faith, after consultation with its outside legal counsel, that the failure by Alexco Board to make an Alexco Change in Recommendation and/or to cause Alexco to terminate this Agreement to enter into Alexco Proposed Agreement, as applicable, would be inconsistent with its fiduciary duties; and

(h) in the case of Alexco Board exercising its rights under clause (2) of this Section 7.2.7, prior to or concurrently with terminating this Agreement pursuant to Section 7.2.7, Alexco enters into such Alexco Proposed Agreement and concurrently pays to Hecla the amounts required to be paid pursuant to Section 7.3.

7.2.8 During Hecla Response Period, or such longer period as Alexco may approve in writing for such purpose: (i) Alexco Board shall review any offer made by Hecla under Section 7.2.7(f) to amend the terms of this Agreement and the Plan of Arrangement in good faith in order to determine whether such proposal would, upon acceptance, result in Acquisition Proposal previously constituting a Superior Proposal ceasing to be a Superior Proposal; and (ii) if Alexco determines that an Acquisition Proposal previously constituting a Superior Proposal would cease to be a Superior Proposal, Alexco shall negotiate in good faith with Hecla to make such amendments to the terms of this Agreement and the Arrangement as would enable Hecla to proceed with the transactions contemplated by this Agreement on such amended terms. If Alexco Board determines that such Acquisition Proposal would cease to be a Superior Proposal, Alexco shall immediately so advise Hecla, and Alexco and Hecla shall amend this Agreement to reflect such offer made by Hecla, and shall take and cause to be taken all such actions as are necessary to give effect to the foregoing.

7.2.9 Each successive amendment or modification to any Acquisition Proposal or Alexco Proposed Agreement that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by Alexco Shareholders or other material terms or conditions thereof shall constitute a new Acquisition Proposal for the purposes of this Section 7.2, and Hecla shall be afforded a new five Business Day Hecla Response Period from the date on which Hecla has received the notice and all documentation referred to in Section 7.2.7(c) and Section 7.2.7(d) with respect to the new Superior Proposal from Alexco.

7.2.10 Alexco Board shall promptly reaffirm Alexco Board Recommendation by press release after Alexco Board determines that any Acquisition Proposal that is publicly announced is not a Superior Proposal or Alexco Board determines that a proposed amendment to the terms of this Agreement as contemplated under Section 7.2.8 would result in an Acquisition Proposal that has been previously announced no longer being a Superior Proposal, and the Agreement has been so amended. Alexco shall provide Hecla and its outside legal counsel with a reasonable opportunity to review the form and content of any such press release and shall make all reasonable amendments to such press release as requested by Hecla and its counsel.

7.2.11 In circumstances where Alexco provides Hecla with notice of a Superior Proposal and all documentation contemplated by Section 7.2.7(c) and Section 7.2.7(d) on a date that is less than seven Business Days prior to the scheduled date of Alexco Meeting, Alexco may either proceed with or postpone Alexco Meeting to a date that is not more than 10 Business Days after the scheduled date of such Alexco Meeting, and shall postpone Alexco Meeting to a date that is not more than 10 Business Days after the scheduled date of such Alexco Meeting if so directed by Hecla.

7.3.3 For the purposes of this Agreement, “Termination Fee” means US$10,000,000.

7.3.4 For the purposes of this Agreement, “Termination Fee Event” means the termination of this Agreement:

(i) within 12 months following the date of such termination Alexco enters into a definitive agreement in respect of an Acquisition Proposal (whether or not such Acquisition Proposal is the same Acquisition Proposal referred to above) and such Acquisition Proposal is later consummated (whether or not within such 12 month period); or

(ii) within 12 months following the date of such termination an Acquisition Proposal is consummated (whether or not such Acquisition Proposal is the same Acquisition Proposal referred to above);

provided that for purposes of this Section 7.3.4(c), the term “Acquisition Proposal” shall have the meaning ascribed to such term in Section 1.1 except that each reference to “20%” therein shall be deemed to be a reference to “50%”.

Any Termination Fee payable pursuant to this Section 7.3.5 shall be paid by wire transfer of immediately available funds.

7.3.6 Each of the Parties acknowledges that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated in this Agreement and that, without those agreements, the Parties would not enter into this Agreement. Each Party acknowledges that all of the payment amounts set out in this Section 7.3 are payments of liquidated damages which are a genuine pre-estimate of the damages which the Party entitled to such damages will suffer or incur as a result of the event giving rise to such damages and the resultant termination of this Agreement and are not penalties. Each of the Parties irrevocably waives any right it may have to raise as a defense that any such liquidated damages are excessive or punitive. For greater certainty, each Party agrees that, upon any termination of this Agreement under circumstances where a Party is entitled to a Termination Fee and such Termination Fee is paid in full, the Party receiving the Termination Fee shall be precluded from any other remedy against the other Party at law or in equity or otherwise (including an order for specific performance), and shall not seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against the other Party or any of its subsidiaries or any of their respective directors, officers, employees, partners, managers, members, shareholders or affiliates in connection with this Agreement or the transactions contemplated hereby.

7.3.7 Nothing in this Section 7.3 shall relieve or have the effect of relieving any Party in any way from liability for damages incurred or suffered by a Party as a result of an intentional or wilful breach of this Agreement.

7.3.8 Nothing in this Section 7.3 shall preclude a Party from seeking injunctive relief to restrain any breach or threatened breach of the covenants or agreements set forth in this Agreement or otherwise to obtain specific performance of any such covenants or agreements, without the necessity of posting bond or security in connection therewith.

7.3.9 For greater certainty, except as provided in Section 7.3.8, a Party shall not be obligated to make more than one payment pursuant to this Section 7.3.

7.4 Access to Information; Confidentiality

(a) From the date hereof until the earlier of the Effective Time and the termination of this Agreement pursuant to its terms, subject to compliance with applicable Laws and COVID-19 Measures and the terms of any existing Contracts, Alexco shall, and shall cause its Representatives to, afford to Hecla and its Representatives, upon reasonable notice, such access as Hecla may reasonably require at all reasonable

Neither Hecla nor any of its Representatives will contact directors, officers, employees, customers, suppliers or other business partners of Alexco or any of its subsidiaries except after receiving the prior written consent of the Chief Executive Officer or Chief Financial Officer of Alexco; provided, however, that the foregoing shall not restrict Hecla from ordinary course business communications and dealings that are unrelated to the Arrangement.

(b) Hecla and Alexco acknowledge and agree that information furnished pursuant to this Section 7.4 shall be subject to the terms and conditions of the Confidentiality Agreement.

Furthermore, this Section 7.5 shall survive the termination of this Agreement as a result of the occurrence of the Effective Date for a period of six years.

This Agreement and the Plan of Arrangement may, at any time and from time to time before or after the holding of the Alexco Meeting but not later than the Effective Time, be amended by mutual written agreement of the Parties and any such amendment may, subject to the Interim Order and the Final Order and applicable Law, without limitation:

- 84 -

breach of this Agreement by a Party, the non-breaching Party will be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance, and the Parties shall not object to the granting of injunctive or other equitable relief on the basis that there exists an adequate remedy at law.

9.4 Time of Essence

Time shall be of the essence in this Agreement.

9.5 Entire Agreement, Binding Effect and Assignment

Hecla may assign all or any part of its rights under this Agreement to, and its obligations under this Agreement may be assumed by, an affiliate of Hecla, provided that if such assignment and/or assumption takes place, Hecla shall continue to be liable jointly and severally with such affiliate for all of its obligations hereunder. Hecla shall provide Alexco with written notice of such assignment on or before 5:00 p.m. (Vancouver time) on the Business Day following such assignment. This Agreement shall be binding on and shall enure to the benefit of the Parties and their respective successors and permitted assigns.

This Agreement (including the exhibits and schedules hereto and the Alexco Disclosure Letter) and the Confidentiality Agreement constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, between the Parties, or any of them, with respect to the subject matter hereof and thereof and, except as expressly provided herein, this Agreement is not intended to and shall not confer upon any person other than the Parties any rights or remedies hereunder. Except as expressly permitted by the terms hereof, neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned by either of the Parties without the prior written consent of the other Party.

9.6 Severability

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law or public policy, that provision will be severed from this Agreement and all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

9.7 Further Assurances

Each Party shall use all commercially reasonable efforts do all such things and provide all such reasonable assurances as may be required to consummate the transactions contemplated by this Agreement, and each Party shall provide such further documents or instruments as reasonably required by any other Party as necessary or desirable to effect the purpose of this Agreement and carry out its provisions, whether before or after the Effective Date.

9.10 Counterparts, Execution

This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument.

Any such certificate formerly representing Alexco Shares not duly surrendered on or before the sixth anniversary of the Effective Date shall:

Hecla, Alexco and the Depositary (in this section, the “payor”), shall each be entitled to deduct and withhold from any Consideration or other amount payable (whether in cash or in kind) or otherwise deliverable to any holder or former holder of Alexco Securities such amounts as the payor may be required to deduct and withhold therefrom under any applicable law in respect of taxes. To the extent that any amounts are so deducted, withheld and remitted to the appropriate governmental entity when required by law, such amounts shall be treated for all purposes under this Plan of Arrangement as having been paid to the person to whom such amounts would otherwise have been paid. To the extent that the amount required to be deducted or withheld from any payment to any holder or former holder of Alexco Shares of the Consideration otherwise payable to such holder, Hecla, Alexco or the Depositary, as applicable, may sell or otherwise dispose of such portion of the Consideration or other amount otherwise payable to such holder or former holder in the form of Hecla Shares as is necessary to provide sufficient funds to enable the payor to comply with such deduction and/or withholding requirements.

NEWS RELEASE

HECLA ACQUIRES ALEXCO RESOURCE

America’s largest and highest-grade silver producer adding

Canada’s largest and highest-grade silver reserve

FOR IMMEDIATE RELEASE

July 5, 2022

COEUR D’ALENE, IDAHO – Hecla Mining Company (NYSE:HL) (Hecla) and Alexco Resource Corp. (NYSE American:AXU; TSX:AXU) (Alexco) are pleased to announce a definitive agreement for Hecla to acquire all of the outstanding common shares of Alexco that Hecla does not already own. Each outstanding common share of Alexco will be exchanged for 0.116 of a share of Hecla common stock implying consideration of US$0.47 per Alexco common share and a premium of 23% based on the companies’ 5-day volume weighted average price on the NYSE and NYSE American on July 1, 2022. In addition, Hecla will (i) provide interim financing to provide working capital and ensure the development and exploration at Keno Hill continues to be advanced and (ii) subscribe for additional common shares bringing its ownership stake to 9.9%.

Hecla has also entered into an agreement with Wheaton Precious Metals Corporation (WPM) to terminate its silver streaming interest at Alexco’s Keno Hill property in exchange for US$135 million of Hecla common stock conditional upon the completion of Hecla’s acquisition of Alexco.

Benefits to Hecla Shareholders

• A large, high-grade silver property in the Yukon, a top 10 rated jurisdiction by the Fraser Institute

• A fully permitted property with infrastructure that includes a 400 tonne per day mill, on-site camp facility, all-season highway access, and connection to the hydropower grid

• Increases Hecla’s silver exposure by increasing proven and probable silver reserves 19% to 237 million ounces, measured and indicated resources 24% to 257 million ounces and inferred resources 7% to 523.7 million ounces

• Potential to be Canada’s largest silver producer

Benefits to Alexco Shareholders

• Delivers an immediate up-front premium to Alexco shareholders

• Allows advancement of Keno Hill’s development with an immediate and non-dilutive interim financing

• Partners with the United States’ largest silver producer

• Transitions from a single asset and its development risk to a diversified production base of long-lived mines and a portfolio of high-quality exploration projects

• A strong balance sheet to invest in Keno Hill and continue its history of resource expansion

• Enhanced capital markets profile with increased analyst coverage and trading liquidity

“At Hecla, we have followed the Keno Hill project closely for a number of years, as it is one of the very few deposits that fit seamlessly into Hecla’s strategy of owning and operating high-grade properties in tier one jurisdictions,” said Phillips S. Baker Jr., President and CEO. “As the United States’ largest silver producer, producing over 40% of silver mined in the U.S., it is natural that Hecla acquires Keno Hill which could also make Hecla Canada’s largest silver producer. Silver is a critical element to decarbonize the economy and the need for domestic supply is growing. Acquiring Keno Hill allows Hecla to further meet this need with a secure high-grade silver development and exploration project that has a small environmental footprint.”

“This transaction delivers significant benefits to our stakeholders,” said Clynton Nauman, Chairman and CEO of Alexco. “By partnering with Hecla, an industry leader in high-grade narrow vein silver mining, we further position Keno Hill to achieve its full potential. There is no doubt that we have fallen well behind the development and production plan at Keno Hill – and our original estimate of achieving commercial production in early 2022. There are myriad reasons for those challenges, but fundamentally, they all led to an increasing level of stress across our business, which was having a negative impact on the share price, our finances, our employees, and other stakeholders. As a much larger business, Hecla has the organizational expertise and financial strength to build Keno Hill to the level and capacity required, while being able to continue to invest in exploration across the district, something that we, as Alexco, independently would likely struggle to achieve. Frankly, the opportunity now afforded to our employees, to the First Nation of Na-Cho Nyäk Dun and the wider Yukon community as a whole is superior to anything Alexco could offer in the short term. I look forward to working with Phil and his team at Hecla to close this transaction in September 2022.”

Terms of the Transaction

The agreement provides Alexco shareholders with 0.116 of a Hecla share for each Alexco common share they hold as of the effective date of the agreement. Hecla will issue approximately 18 million common shares to Alexco shareholders. Upon completion of the transactions with both WPM and Alexco, and assuming the July 1, 2022 5-day volume weighted average price of Hecla’s shares of US$4.13, WPM and Alexco shareholders will own approximately 5.6% and 3.0%, respectively, of the outstanding common shares of Hecla. The exact number of Hecla common shares to be issued to WPM will be calculated immediately before the closing date.

Hecla is providing Alexco with a US$30 million secured loan facility and is purchasing 8,984,100 Alexco Shares at C$0.50 per share, having an aggregate value of C$4,492,050, which will result in 9.9% of Alexco Shares being held by Hecla or its affiliates. A portion of the loan will be immediately drawn and the remainder available on a revolving basis, and the use of proceeds will be for agreed upon working capital and capital expenditures purposes according to a plan jointly approved by Alexco and Hecla. The loan and share purchase are intended to provide Alexco with immediate working capital to continue development work at Keno Hill and are not conditional upon the completion of the transaction.

Board of Directors’ Recommendations

The Board of Directors of Alexco and Hecla have both unanimously approved the transaction. The Board of Directors of Alexco unanimously recommends that Alexco shareholders vote in favor of the transaction. Alexco’s directors and officers support the transaction and have entered into customary voting support agreements with Hecla agreeing to vote their Alexco shares in favor of the transaction. WPM has also entered into a voting support agreement with Hecla to vote its Alexco shares in favor of the transaction, resulting in approximately 4.9% of Alexco’s outstanding common shares being subject to voting support agreements to support the transaction.

Cormark Securities Inc. provided an opinion to the Alexco Board of Directors that the transaction is fair from a financial point of view to Alexco shareholders as of the date of the arrangement agreement, and subject to the assumptions, limitations and qualifications in the opinion.

Transaction Conditions and Timing

The transaction will be implemented by a Court-approved plan of arrangement under the Business Corporations Act (British Columbia) and requires the approval of: (i) 66 2/3% of the votes cast by the holders of Alexco’s common shares, (ii) 66 2/3% of the votes cast by the affected securityholders of Alexco voting as a single class, and (iii) if applicable, a majority of the votes cast by the holders of Alexco’s common shares after excluding any votes of Hecla and other persons required to be excluded under Canadian Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions, all at a special meeting.

Cautionary Statements to Investors on Reserves and Resources

This news release uses the terms “mineral resources,” “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources.” Mineral resources that are not mineral reserves do not have demonstrated economic viability. You should not assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. Further, inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically, and an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve. On October 31, 2018, the SEC

adopted new mining disclosure rules (“S-K 1300”) that is more closely aligned with current industry and global regulatory practices and standards, including National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) which Hecla complies with because it also is a “reporting issuer” under Canadian securities laws. While S-K 1300 is more closely aligned with NI 43-101 than the prior SEC mining disclosure rules, there are some differences. NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all resource and reserve estimates contained in this press release have been prepared in accordance with NI 43-101, as well as S K 1300.

Qualified Person (QP)

Kurt D. Allen, MSc., CPG, VP – Exploration of Hecla Mining Company and Keith Blair, MSc., CPG, Chief Geologist of Hecla Limited, who serve as a Qualified Person under S-K 1300 and “NI 43-101”, supervised the preparation of the scientific and technical information concerning Hecla’s mineral projects in this news release.

⁽¹⁾ The term “reserve” means an estimate of tonnage and grade or quality of indicated and measured resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is an economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. The term “proven reserves’ means the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource. Reserves are reported in accordance with Section 1300 of Regulation S-K of the Securities Act of 1933, as amended and NI 43-101. See footnotes 7 and 8 below.

⁽²⁾ Mineral reserves are based on $17/oz silver, $1600/oz gold, $0.90/lb lead, $1.15/lb zinc, unless otherwise stated.

⁽³⁾ The reserve NSR cut-off grades for Greens Creek are $215/ton for all zones at Greens Creek except the Gallagher Zone at $220/ton; metallurgical recoveries (actual 2021): 81.26% silver, 72.34% gold, 82.29% lead, 89.58% zinc

⁽⁴⁾ The reserve NSR cut-off grades for Lucky Friday are $216.19 for the 30 Vein and $230.98 for the Intermediate Veins; metallurgical recoveries (actual 2021): 95.18% silver, 94.62% lead, 89.97% zinc

⁽⁵⁾  The average reserve cut-off grades at Casa Berardi are 0.101 oz/ton gold (3.47 g/tonne) for underground and 0.037 oz/ton (1.27 g/tonne) for open pit. Metallurgical recovery (actual 2021): 84.82% gold; US$/CAN$ exchange rate: 1:1.275.

⁽⁶⁾  The term “probable reserves” means the economically mineable part of an indicated and, in some cases, a measured mineral resource. See footnotes 8 and 9 below.

Note: All estimates are in-situ except for the proven reserves at Greens Creek which are in surface stockpiles. Mineral resources are exclusive of reserves.

⁽⁷⁾ The term “mineral resources” means a concentration or occurrence of material of economic interest in or on the Earth’s crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled. Resources are reported in accordance with Section 1300 of Regulation S-K of the Securities Act of 1933, as amended and NI 43-101.

⁽⁸⁾ The term “measured resources” means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors, as defined in this section, in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

⁽⁹⁾ The term “indicated resources” means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.

⁽¹⁰⁾  The term “inferred resources” means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve.

ALEXCO ACQUISITION America’s Largest Silver Miner To Become Canada’s Largest July 5, 2022 RESPONSIBLE. SAFE. INNOVATIVE. Exhibit 99.2

CAUTIONARY STATEMENTS RESPONSIBLE. SAFE. INNOVATIVE. l Cautionary Statement Regarding Forward-Looking Statements This presentation contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which are intended to be covered by the safe harbor created by such sections and other applicable laws, including Canadian securities laws. When a forward-looking statement expresses or implies an expectation or belief as to future events or results, such expectation or belief is expressed in good faith and believed to have a reasonable basis. However, such statements are subject to risks, uncertainties and other factors, which could cause actual results to differ materially from future results expressed, projected or implied by the forward-looking statements. Forward-looking statements often address our expected future business and financial performance and financial condition and often contain words such as “anticipate,” “intend,” “plan,” “will,” “could,” “would,” “estimate,” “should,” “expect,” “believe,” “project,” “target,” “indicative,” “preliminary,” “potential” and similar expressions. Forward-looking statements in this news release may include, without limitation statements or information regarding the (i) completion of Hecla’s acquisition of Alexco and that it will close in the third quarter, (ii) the termination of WPM’s stream on the Keno Hill project, (iii) the listed “benefits to Hecla shareholders,” (iv) the listed “benefits to Alexco shareholders,” and (v) that Hecla has the organizational expertise and financial strength to build Keno Hill to the level and capacity required, while being able to continue to invest in exploration across the district. The material factors or assumptions used to develop such forward-looking statements or forward-looking information include that the Company’s plans for development and production will proceed as expected and will not require revision as a result of risks or uncertainties, whether known, unknown or unanticipated, to which the Company’s operations are subject. Estimates or expectations of future events or results are based upon certain assumptions, which may prove to be incorrect, which could cause actual results to differ from forward-looking statements. Such assumptions, include, but are not limited to: (i) there being no significant change to current geotechnical, metallurgical, hydrological and other physical conditions; (ii) permitting, development, operations and expansion of the Company’s projects being consistent with current expectations and mine plans; (iii) political/regulatory developments in any jurisdiction in which the Company operates being consistent with its current expectations; (iv) the exchange rate for the USD/CAD and USD/MXN, being approximately consistent with current levels; (v) certain price assumptions for gold, silver, lead and zinc; (vi) prices for key supplies being approximately consistent with current levels; (vii) the accuracy of our current mineral reserve and mineral resource estimates; (viii) the Company’s plans for development and production will proceed as expected and will not require revision as a result of risks or uncertainties, whether known, unknown or unanticipated; (ix) counterparties performing their obligations under hedging instruments and put option contracts; (x) sufficient workforce is available and trained to perform assigned tasks; (xi) weather patterns and rain/snowfall within normal seasonal ranges so as not to impact operations; (xii) relations with interested parties, including Native Americans, remain productive; (xiii) economic terms can be reached with third-party mill operators who have capacity to process our ore; (xiv) maintaining availability of water rights; (xv) factors do not arise that reduce available cash balances; and (xvi) there being no material increases in our current requirements to post or maintain reclamation and performance bonds or collateral related thereto. In addition, material risks that could cause actual results to differ from forward-looking statements include, but are not limited to: (i) gold, silver and other metals price volatility; (ii) operating risks; (iii) currency fluctuations; (iv) increased production costs and variances in ore grade or recovery rates from those assumed in mining plans; (v) community relations; (vi) conflict resolution and outcome of projects or oppositions; (vii) litigation, political, regulatory, labor and environmental risks; (viii) exploration risks and results, including that mineral resources are not mineral reserves, they do not have demonstrated economic viability and there is no certainty that they can be upgraded to mineral reserves through continued exploration; (ix) the failure of counterparties to perform their obligations under hedging instruments; (x) we take a material impairment charge on our Nevada operations; (xi) we are unable to remain in compliance with all terms of the credit agreement in order to maintain continued access to the revolver, and (xii) we are unable to refinance the maturing senior notes. For a more detailed discussion of such risks and other factors, see the Company’s 2021 Form 10-K, filed on February 23, 2022, with the Securities and Exchange Commission (SEC), as well as the Company’s other SEC filings. The Company does not undertake any obligation to release publicly revisions to any “forward-looking statement,” including, without limitation, outlook, to reflect events or circumstances after the date of this presentation or to reflect the occurrence of unanticipated events, except as may be required under applicable securities laws. Investors should not assume that any lack of update to a previously issued “forward-looking statement” constitutes a reaffirmation of that statement. Continued reliance on “forward-looking statements” is at investors’ own risk. Cautionary Statement to Investors on Reserves and Resources This news release uses the terms “mineral resources,” “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources.” Mineral resources that are not mineral reserves do not have demonstrated economic viability. You should not assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. Further, inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically, and an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve. On October 31, 2018, the SEC adopted new mining disclosure rules (“S-K 1300”) that is more closely aligned with current industry and global regulatory practices and standards, including National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) which Hecla complies with because it also is a “reporting issuer” under Canadian securities laws. While S-K 1300 is more closely aligned with NI 43-101 than the prior SEC mining disclosure rules, there are some differences. NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure NI 43-101

ALEXCO RESERVES & RESOURCE SUMMARY RESPONSIBLE. SAFE. INNOVATIVE. l MINERAL RESERVES MINERAL RESOURCES

PROVEN & PROBABLE MINERAL RESERVES(1) RESPONSIBLE. SAFE. INNOVATIVE. l (On December 31, 2021 unless otherwise noted) Investors are cautioned that Reserves and Resources are as of December 31, 2021, and are dynamic during the year due to mining depletion, changing metal prices, changing costs or project economics, and new drill or mining information. These factors can impact Reserves and Resources either positively or negatively.

MEASURED AND INDICATED MINERAL RESOURCES RESPONSIBLE. SAFE. INNOVATIVE. l (On December 31, 2021 unless otherwise noted) Investors are cautioned that Reserves and Resources are as of December 31, 2021, and are dynamic during the year due to mining depletion, changing metal prices, changing costs or project economics, and new drill or mining information. These factors can impact Reserves and Resources either positively or negatively.

INFERRED MINERAL RESOURCES RESPONSIBLE. SAFE. INNOVATIVE. l (On December 31, 2021 unless otherwise noted) Investors are cautioned that Reserves and Resources are as of December 31, 2021, and are dynamic during the year due to mining depletion, changing metal prices, changing costs or project economics, and new drill or mining information. These factors can impact Reserves and Resources either positively or negatively.

MINERAL RESOURCES FOOTNOTES RESPONSIBLE. SAFE. INNOVATIVE. l (7) The term "mineral resources" means a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled. Resources are reported in accordance with Section 1300 of Regulation S-K of the Securities Act of 1933, as amended and NI 43-101. (8) The term "measured resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors, as defined in this section, in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve. (9) The term "indicated resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve. (10) The term "inferred resources" means that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve. (11) Mineral resources are based on $1700/oz gold, $21/oz silver, $1.15/lb lead, $1.35/lb zinc and $3.00/lb copper, unless otherwise stated. (12) The resource NSR cut-off grades for Greens Creek are $215/ton for all zones at Greens Creek except the Gallagher Zone at $220/ton; metallurgical recoveries (actual 2021): 81.26% silver, 72.34% gold, 82.29% lead, 89.58% zinc. (13) The resource NSR cut-off grades for Lucky Friday are $170.18 for the 30 Vein, $184.97 for the Intermediate Veins and $207.15 for the Lucky Friday Vein; metallurgical recoveries (actual 2021): 95.18% silver, 94.62% lead, 89.97% zinc. (14) The average resource cut-off grades at Casa Berardi are 0.089 oz/ton gold (3.06 g/tonne) for underground and 0.036 oz/ton (1.22 g/tonne) for open pit; metallurgical recovery (actual 2021): 84.82% gold; US$/CAN$ exchange rate: 1:1.275. (15) Indicated resources for most zones at San Sebastian based on $1500/oz gold, $21/oz silver, $1.15/lb lead, $1.35/lb zinc and $3.00/lb copper using a cut-off grade of $90.72/ton ($100/tonne); $1700/oz gold used for Toro, Bronco, and Tigre zones. Metallurgical recoveries based on grade dependent recovery curves: recoveries at the mean resource grade average 89% silver and 84% gold for oxide material and 85% silver, 83% gold, 81% lead, 86% zinc, and 83% for copper for sulfide material. Resources reported at a minimum mining width of 8.2 feet (2.5m) for Middle Vein, North Vein, and East Francine, 6.5ft (1.98m) for El Toro, El Bronco, and El Tigre, and 4.9 feet (1.5 m) for Hugh Zone and Andrea. (16) Mineral resources for Fire Creek, Hollister and Midas are reported using $1500/oz gold and $21/oz silver prices, unless otherwise noted. A minimum mining width is defined as four feet or the vein true thickness plus two feet, whichever is greater. (17) Fire Creek mineral resources are reported at a gold equivalent cut-off grade of 0.283 oz/ton. Metallurgical recoveries: 90% gold, 70% silver. (18) Hollister mineral resources, including the Hatter Graben are reported at a gold equivalent cut-off grade of 0.238 oz/ton.
