VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 12, 2013) - The Board of Directors of Aurizon Mines Ltd. ("Aurizon" or the "Company") (TSX:ARZ)(NYSE MKT:AZK) announced today that the previously announced special meeting (the " Meeting ") of the shareholders (" Aurizon Shareholders ") and optionholders of Aurizon (" Aurizon Optionholders ") and (together with Aurizon Shareholders, " Aurizon Securityholders ") will be held on May 9, 2013 at The Vancouver Club, in the University Room, 3 ^rd Floor, 915 West Hastings Street, Vancouver, BC, V6C 1C6 at 1:00 p.m. PST, and that it has mailed the Management Information Proxy Circular (the " Proxy Circular ") dated April 10, 2013 to Aurizon Securityholders in connection with the Meeting.

At the Meeting, Aurizon Securityholders will be asked to consider and, approve a special resolution (the " Arrangement Resolution ") with respect to the proposed transaction (the " Hecla Arrangement ") whereby a wholly-owned subsidiary of Hecla Mining Company (" Hecla ") will acquire all of the issued and outstanding common shares of Aurizon (the " Aurizon Shares ").

The board of directors of Aurizon (the "Aurizon Board") unanimously recommends that Aurizon Securityholders vote to approve the Hecla Arrangement, and each of the directors and senior officers of Aurizon has agreed to support the Hecla Arrangement.

David P. Hall, Chairman of Aurizon said: "The Hecla Arrangement offers attractive value, including a substantial cash component, and the compelling opportunity to participate in a North American focused precious metals company with operating mines in Alaska, Idaho and Quebec and significant exploration potential and upside. The Aurizon Board unanimously agrees that this arrangement is fair to Aurizon Securityholders and recommends that Aurizon Securityholders vote in favour of the Arrangement Resolution."

Added Mr. Hall: "We encourage all Securityholders, no matter how many securities they hold, to review the Management Information Proxy Circular, and vote in favour of the Hecla Arrangement either at the Special Meeting or by proxy."

In making its recommendation, the Aurizon Board considered a number of factors as described in the Proxy Circular, including those set out under the heading "The Arrangement-Recommendation of the Aurizon Board".

About the Hecla Arrangement

Under the terms of the Hecla Arrangement Aurizon Shareholders may elect to receive, in exchange for each Aurizon Share, $4.75 or 0.9953 of a share of Hecla common stock (a " Hecla Share ") or a combination of both, subject in each case to pro-ration based on a maximum cash consideration of approximately $513.6 million and a maximum share consideration of 57 million Hecla Shares. Assuming that all Aurizon Shareholders elect to receive either cash or Hecla Shares, the consideration will be fully pro-rated with each Aurizon Shareholder being entitled to receive $3.11 in cash and 0.3446 of a Hecla Share for each Aurizon Share.

In addition, each option to purchase Aurizon Shares ("Aurizon Options") that has an exercise price of less than $4.75 per share will, without any further action by or on behalf of any Aurizon Optionholder, be deemed to be fully vested and transferred and disposed of by the holder thereof to Aurizon (free and clear of all liens, claims and encumbrances) and cancelled in exchange for the Option Consideration, as described in the Proxy Circular. Aurizon Shares received as Option Consideration will be subject to the election and pro-ration provisions of the Arrangement. Aurizon Options that have an exercise price that is greater than $4.75 per share will be cancelled.
