Business Wire

COEUR D’ALENE, Idaho -- March 5, 2013

Hecla Mining Company (NYSE:HL) (Hecla) (Company) today reiterated the
superiority of its agreed-upon transaction with Aurizon Mines Ltd. (TSX:ARZ)
(NYSE:AZK) (Aurizon), announced on March 4, 2013, and strongly urges
shareholders to reject the Alamos offer.

President and Chief Executive officer, Phillips S. Baker, Jr. said, "Our offer
is superior to the Alamos offer by CAD$0.27, based on yesterday’s closing
prices, and includes a 68% higher cash component. Tendering to the Alamos
offer risks depriving Aurizon shareholders of the premium our offer represents
as well as the significant upside we see in a Hecla-Aurizon combination.As a
North America focused precious metals producer, we believethe combined
company will deliver increased value well into the future."

Hecla’s arrangement agreement is superior to the unsolicited Alamos offer for
many reasons, included but not limited to:

  *Implied value is superior – Implied value of Hecla’s offer of CAD$4.55,
    based on closing prices on March 4, 2013, represents a CAD$0.27 premium to
    the current implied value of Alamos offer of C$4.28
  *Larger cash component – Hecla’s agreement has a 68% higher cash component
    than the Alamos offer
  *Superior business logic – the combined company will have low cost
    operating mines with long lives in mining friendly jurisdictions
  *Reduced operating risk – 120 years of mining experience, most of it in
    underground mines similar to Casa Berardi
  *Growth opportunities – enhanced exposure to exploration and
    pre-development projects

Separately, Aurizon today reiterated its recommendation that shareholders
support the Hecla transaction and do not tender into the Alamos offer or
withdraw tenders already made. Aurizon urged shareholders who have tendered to
immediately withdraw tendered shares.

Mr. Baker continued, “We believe that the combination of Aurizon and Hecla
provides the best opportunity for operational synergies and the creation of
lasting value for shareholders. The new company will have three long life low
cost assets in mining friendly jurisdictions. We have followed Aurizon and
Casa Berardi for the past 7 years and believe strongly in the asset, its
exploration upside, and the benefits of where the project is located. We
invite the Aurizon shareholders to join us as we build a leading diversified
silver and gold producer.”
