VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 24, 2013) - The Board of Directors of Aurizon Mines Ltd. (TSX:ARZ)(NYSE MKT:AZK) ("Aurizon" or the "Company") announced today that Institutional Shareholder Services Inc. ("ISS") has recommended that its clients vote FOR a special resolution approving the proposed transaction whereby Hecla Mining Company ("Hecla") will acquire all of the issued and outstanding common shares of Aurizon, in exchange for CAD$4.75 per Aurizon 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 (the "Hecla Arrangement").

ISS is a leading independent international corporate governance analysis and proxy advisory firm. ISS makes its recommendation after carefully considering what is in the best interests of shareholders. Its recommendations assist shareholders in making voting choices regarding proxy voting decisions.

In making its recommendation that Aurizon shareholders vote FOR the resolution pertaining to the Hecla Arrangement, ISS said:

"It appears that the Hecla Arrangement represents a superior proposal to the prior Alamos offer. The Arrangement provides a maximum Cash Consideration of approximately $513.6 million, 68% higher than the maximum $305 million cash that was available under the Alamos offer. In light of the improved transaction terms, the significant premium and no significant governance concerns, a vote FOR this resolution is warranted."*

The board of directors of Aurizon 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.

Said David Hall, Chairman of Aurizon: "We are pleased that ISS has affirmed our recommendation that Aurizon securityholders vote in favour of the Hecla Arrangement at the Special Meeting in person or by proxy.
