VANCOUVER, BC, Aug. 18, 2022 /PRNewswire/ - Alexco Resource Corp. (NYSE American: AXU) (TSX: AXU) ("Alexco" or the "Company") is pleased to announce that a second independent, third-party proxy advisory firm, Glass Lewis & Co. LLC ("Glass Lewis") has recommended Alexco shareholders ("Alexco Shareholders") vote "FOR" the proposed acquisition of Alexco by 1080980 B.C. Ltd. ("108"), a subsidiary of Hecla Mining Company ("Hecla") at the upcoming special meeting of securityholders to be held on Tuesday, August 30, 2022, at 10:00 a.m. (Pacific Time) (the "Meeting").

At the Meeting, securityholders will be asked to consider and, if deemed advisable, pass a special resolution (the "Arrangement Resolution") to approve an arrangement (the "Arrangement"), in accordance with the terms of an arrangement agreement entered into by the Company and Hecla on July 4, 2022, as assigned and amended (the "Arrangement Agreement") pursuant to which 108 will acquire all of the issued and outstanding common shares of Alexco (the "Alexco Shares") that it does not already own by way of a statutory plan of arrangement under the Business Corporations Act (British Columbia). Under the terms of the Arrangement, Alexco Shareholders will receive 0.116 common shares in the capital of Hecla (each common share, a "Hecla Share") for each Alexco Share held (the "Consideration").

In their report, Glass Lewis noted: "Based on the compelling rationale underpinning the proposed merger, as well as reasonable financial terms, we believe that the proposed merger warrants shareholder support."

Alexco's board of directors UNANIMOUSLY recommends that securityholders
VOTE FOR the Arrangement Resolution

In evaluating and unanimously approving the Arrangement, the special committee of independent Alexco directors (the "Special Committee") and the board of directors of Alexco (the "Board") gave careful consideration to the current position and condition and the expected and potential future position and condition of the business of the Company, and all terms of the Arrangement Agreement, including the conditions precedent, representations and warranties and deal protection provisions. The Special Committee and the Board considered a number of factors including, among others, the following:

• Premium. The Consideration to be received by Alexco Shareholders pursuant to the Arrangement represents a premium of 12% on a spot basis to the July 1, 2022 closing price, and 24% premium using the trailing 5-day volume weighted average trading price on the NYSE American for Alexco Shares and the NYSE for Hecla Shares as of market close on July 1, 2022.
• Liquidity. Based on the immediate financing requirements, the business, operations, financial condition and prospects of the Company, as well as the current and prospective environment in which the Company operates, including macroeconomic conditions in Canada and globally, there is a significant risk that the Alexco Shares could continue to trade below US$0.417, the closing price as at July 1, 2022, over the short to medium term. The Consideration provides Alexco Shareholders with immediate liquidity at a price that may not be available in the absence of the Arrangement.
• Strengths and Strategic Fit. If the Arrangement is completed, it is expected that Alexco Shareholders will benefit from:

Alexco Shareholders will also be able to continue to participate in the potential upside from any exploration and development success related to the properties of Alexco, as well as the other properties of Hecla. It is expected that Alexco Shareholders will hold approximately 3% of the Hecla Shares on an outstanding undiluted basis upon completion of the Arrangement.
• Process. The Arrangement with Hecla resulted from discussions that began months ago. During that time, the management and financial advisors of Alexco communicated with several other parties regarding potential transactions. Confidentiality agreements were entered into with seven potential acquirors or merger partners. Discussions were held with each. The Arrangement is the most attractive of those alternatives. All potential acquirors or merger partners expressed the view that existing silver purchase agreement between Wheaton Precious Metals Corp. ("Wheaton") and Alexco and certain of its subsidiaries (the "Wheaton Stream Agreement") would require amendment to ensure the financial viability of Alexco's conventional mining and milling of silver-lead-zinc ore from certain deposits in the Keno Hill District in Yukon, Canada (the "Keno Hill Project"). Of all of the parties the Company approached, only Hecla was successful in negotiating satisfactory arrangements with Wheaton with respect to the Wheaton Stream Agreement.
• Business and Industry Risks. The business, operations, assets, financial condition, operating results and prospects of Alexco are subject to significant uncertainty, including risks associated with Wheaton's silver purchase streaming rights on its Keno Hill Project, risks associated with a negative working capital position, and risks associated with obtaining financing on acceptable terms or at all. The Special Committee concluded that the Company immediately required additional financing and of the financing alternatives, the Arrangement provided a more favourable outcome to the Company and its stakeholders than any other option that was reasonably available. Further, the Special Committee determined that the Consideration under the Arrangement is more favourable to Alexco Shareholders than continuing with Alexco's current business plan in light of these risks and uncertainties.

The management information circular dated July 28, 2022 and related meeting materials (collectively, the "Meeting Materials") have been filed by the Company on SEDAR and EDGAR and are available under the Company's profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov. The Meeting Materials are also available on the Company's website at Alexco - Investors - Special Meeting (https://alexcoresource.com/investors/special-meeting-of-shareholders/).
