Business Wire, Dec 13, 2007

COEUR D'ALENE, Idaho -- Hecla Mining Company (NYSE:HL) today announced that it has set the price for the public offering of 1.75 million shares of 6.5% mandatory convertible preferred stock ("Preferred Stock") at $100.00 per share. The Preferred Stock will pay, when declared by the Board of Directors, dividends at a rate of 6.5% per annum, payable quarterly. Hecla Mining Company (Hecla) will pay dividends in cash, common stock or a combination of cash and common stock. The first dividend payment date will be April 1, 2008. The underwriters have an option to purchase up to an additional 262,500 shares of Preferred Stock to cover over-allotments, if any.

The estimated net proceeds to Hecla from the Preferred Stock offering (assuming the exercise in full of the underwriters' over-allotment option) are expected to be approximately $194.7 million. Hecla currently intends to use the net proceeds from this offering for general corporate purposes, including possible acquisitions of other businesses, securities, assets, properties or mining projects, claims or interests, as further described in the prospectus supplement for the offering.

Each share of the Preferred Stock will automatically convert on January 1, 2011, into between approximately 8.4502 and 10.3093 shares of Hecla common stock if not converted earlier. The conversion rates will be subject to anti-dilution adjustments in certain circumstances. Holders may elect to convert at any time prior to January 1, 2011, at a conversion rate equal to 8.4502 shares of common stock for each share of Preferred Stock, subject to adjustments. Hecla may cause the conversion of all of the shares of Preferred Stock at its option at any time on or prior to July 1, 2008, unless it has completed a material transaction involving the acquisition of assets or a business with a purchase price of $100 million or more on or prior to that date. The conversion at the company's option prior to July 1, 2008, can be to common stock, to cash or a combination of both.
