Dear Coeur Shareholder:

        Please find enclosed additional proxy material relating to the Adjourned Annual Meeting scheduled to be held on June 3, 2005 at 9:30am, Pacific Standard Time, at our office located at 505 Front Street, Coeur d’ Alene, Idaho 83816.

        Due to recent changes enacted by the New York Stock Exchange, brokers can no longer vote for share incentive plans, and shareholders must vote their own shares to approve such plans. To date, although the overwhelming majority of votes cast have been in favor of the proposed share plan, we have not yet obtained the necessary majority of outstanding shares voting on the proposal needed to pass Proposal #2 relating to the 2005 Non-Employee Directors’ Equity Incentive Plan as stated in the 2005 Notice of Annual Meeting.

        Your shares may not be voted on this issue without your specific voting instructions. Accordingly, we are furnishing you an additional Voting Instruction Form to enable you to instruct your broker how you wish your shares to be voted. The quickest way to have your shares counted is to vote via the telephone or the internet. Instructions on how to vote over the phone or internet are enclosed in this package.

        Your shares cannot be represented at the Adjourned Annual Meeting with respect to Proposal #2 unless you either sign and return the enclosed voting form or vote by telephone or over the internet.

        If you sign and return the enclosed from without indicating a choice of “for”, “against” or “abstain”, your shares will be voted as recommended by your Board of Directors. Adjournments result in additional costs to the company, so please help us achieve this vote. To ensure your shares are counted at the adjourned annual meeting we urge you to vote today.

        If you have questions or need help voting your shares, please call our proxy solicitation firm, Morrow & Co., Inc. at 800-607-0088.

  Regards,
 
/s/ Dennis E. Wheeler
