Terms defined in the Offering Circular shall have the same meaning in this Amended Statement. To the extent this Amended Statement contains information not contained in the Offering Circular, the information herein amends the Offering Circular. The Offering Circular, as amended hereby, and the Letter of Transmittal, as they may be further amended or supplemented, together constitute the "Offer." Hecla Mining Company announced the final results of the Offer, which expired at 12:00 Midnight, New York City time, on February 20, 2004. Based on a final count by American Stock Transfer & Trust Company, the Exchange Agent for the Offer, 273,961 shares were properly tendered and not withdrawn. Hecla has accepted all of the properly tendered shares. Delivery of shares of Hecla common stock in exchange for accepted shares is being made by American Stock Transfer & Trust Company. Hecla commenced the Offer on January 9, 2004, at which time there were 464,777 shares of Series B Cumulative Convertible Preferred stock issued and outstanding. As a result of the completion of the exchange offer, Hecla has 190,816 shares of Series B Cumulative Convertible Preferred stock issued and outstanding as of the time immediately following issuance of the exchanged shares. As a result of the exchange, the outstanding shares of common stock increased from 115,756,505 to 117,931,742. Hecla will be required to take a one-time noncash dividend charge against earnings in the first quarter in the amount of $9.6 million as a result of the tender offer. Accounting principles require the disclosure and presentation on the income statement of the fair market value of the additional shares exchanged above the original exchange ratio of 3.2154 shares of common stock for each share of Preferred B stock. This dividend is noncash and does not impact the total equity on the company's balance sheet. 1 SIGNATURE After due inquiry and to the best of my knowledge and belief, I certify that the information set forth in this Amended Statement is true, complete and correct.
