Aurizon Enters into Definitive Agreement with Hecla

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 4, 2013) - The Board of Directors of Aurizon Mines Ltd. (TSX:ARZ)(NYSE MKT:AZK) ("Aurizon" or the "Company") today announced that it has entered into a definitive agreement pursuant to which Hecla Mining Company (NYSE:HL) will acquire all of the outstanding diluted common shares of Aurizon for approximately CAD$796 million. The transaction will be implemented by way of a plan of arrangement (the "Arrangement") under the Business Corporations Act (British Columbia).

Under the terms of the Arrangement, Aurizon shareholders may elect to receive in exchange for each Aurizon Share, CAD$4.75 per share or 0.9953 of a Hecla share or a combination of both, subject in each case to pro-ration based on a maximum cash consideration of approximately CAD$513.6 million and a maximum of approximately 57,000,000 Hecla shares. Assuming that all shareholders elect to receive either cash or Hecla shares, the consideration will be fully pro-rated with each shareholder being entitled to receive CAD$3.11 in cash and 0.3446 of a Hecla share for each Aurizon share.

The CAD$4.75 per share offer price represents an approximately 12% premium to the current implied CAD$4.26 per share value of the Alamos Offer based on the closing share price of Alamos Gold Inc. on March 1, 2013 and assuming that all shareholders elected to receive cash or shares.

George Brack, Chair of the Special Committee of the Aurizon Board of Directors said: "We are pleased that our rigorous process to seek value-maximizing alternatives has resulted in an agreement with Hecla which resulted in additional value for Aurizon shareholders. The agreement with Hecla provides Aurizon shareholders with an attractive premium, value certainty through a substantial cash consideration component and an opportunity to participate in the upside potential of a combined CAD$1.6 billion company with a world class asset portfolio located in politically stable and proven mining jurisdictions."

The Board of Directors of Aurizon, acting on the recommendation of its special committee of independent directors, after consultation with its financial and legal advisors, has determined that the transaction is fair to Aurizon's securityholders and in the best interests of Aurizon. Scotia Capital Inc. and CIBC World Markets Inc. have each delivered an opinion to the Aurizon Board of Directors and Special Committee, respectively, that, based upon and subject to the assumptions, limitations and qualifications set forth in the opinion, the consideration offered by Hecla pursuant to the Arrangement is fair, from a financial point of view to the Aurizon shareholders other than Hecla and its affiliates.

The Arrangement will require the approval of 66 2/3% of the votes cast by the affected securityholders of Aurizon voting as a single class and the approval of 66 2/3% of the votes cast by the Aurizon Shareholders at a special meeting which is expected to take place in May, 2013. Assuming Aurizon securityholders approve the transaction at the special meeting and all court and regulatory approvals are obtained, the transaction is expected to close in the second quarter of 2013.

The Arrangement Agreement provides for, among other things, a non-solicitation covenant on the part of Aurizon (subject to customary fiduciary out provisions). The Arrangement Agreement also provides Hecla with a "right to match" any competing offer which constitutes a superior proposal and the Arrangement Agreement requires Aurizon to pay a termination fee of CAD$27.2 million or to reimburse Hecla's expenses in certain circumstances.

Details of the Arrangement, including a summary of the terms and conditions of the Arrangement Agreement, will be disclosed in a Management Information Circular of Aurizon which will be mailed to Shareholders and other affected security holders of Aurizon.

The Board of Directors of Aurizon unanimously recommends to Aurizon Securityholders that they vote to approve the Arrangement and continues to recommend that shareholders REJECT the previously announced offer by Alamos Gold Inc.
