COEUR D'ALENE, Idaho (Business Wire) -- Hecla Mining Company (NYSE:HL) (“Hecla”) has posted to its website (www.hecla-mining.com) an investor presentation regarding its offers to acquire all of the outstanding common shares of U.S. Silver Corporation (TSX:USA) (“U.S. Silver”) for CDN$1.80 per common share in cash and to acquire each outstanding common share purchase warrant for CDN
.205 (its “in the money” amount based on such price per common share) (together, the “Hecla Offer”).

More specifically, the presentation outlines the benefits of the Hecla Offer, the risks associated with the proposed U.S. Silver-RX Gold and Silver (“RX”) transaction and the steps that U.S. Silver shareholders need to take to vote against the proposed RX transaction prior to the voting deadline.

The Hecla Offer is conditional upon the proposed RX transaction not proceeding or such transaction otherwise terminating; U.S. Silver shareholders need to REVOKE proxies voted for the RX Proposal (if your shares have been previously voted for it) and vote AGAINST it immediately, before the August 2, 2012 proxy voting deadline.

Instructions for Beneficial U.S. Silver Shareholders

If you are a beneficial U.S. Silver Shareholder, call your investment advisor, stockbroker, bank, trust company, other nominee or intermediary through which you hold your U.S. Silver shares immediately and instruct them to vote AGAINST the proposed RX transaction. Brokers and other intermediaries each have their own voting instructions, which need to be carefully followed to ensure that your instructions are counted. It is also important to note that your broker or other intermediary may have a deadline that falls before August 2, 2012. Therefore, it is imperative that you act immediately.
