KLONDEX MINES INVESTOR ALERT by the Former Attorney General of Louisiana: Kahn Swick & Foti, LLC Investigates Adequacy of Price and Process in Proposed Sale of Klondex Mines Ltd.

Former Attorney General of Louisiana Charles C. Foti, Jr., Esq. and the law firm of Kahn Swick & Foti, LLC (“KSF”) are investigating the proposed sale of Klondex Mines Ltd. (“Klondex” or the “Company”) (NYSE: KLDX) to Hecla Mining Company (“Hecla”) (NYSE: HL). Under the terms of the proposed transaction, shareholders of Klondex may elect to receive $2.47 in cash OR 0.6272 of a Hecla share for each share of Klondex that they own. If all Klondex shareholders elect either the cash alternative or the share alternative, each Klondex shareholder would be entitled to receive $0.8411 in cash and 0.4136 Hecla shares. Further, Klondex shareholders who fail to make an election will automatically receive $0.8411 in cash and 0.4136 of a Hecla share. KSF is seeking to determine whether this consideration and the process that led to it are adequate, or whether the consideration undervalues the Company.

If you believe that this transaction undervalues the Company and/or if you would like to discuss your legal rights regarding the proposed sale, you may, without obligation or cost to you, e-mail or call KSF Managing Partner Lewis S. Kahn (lewis.kahn@ksfcounsel.com) toll free at any time at 855-768-1857, or visit https://www.ksfcounsel.com/cases/nyse-kldx/ to learn more.
