Press Release

COEUR COMMENTS ON WHEATON RIVER BOARD ANNOUNCEMENT

COEUR OFFERS SUPERIOR PROPOSAL

     Coeur d’Alene, Idaho – May 31, 2004 – Coeur d’Alene Mines Corporation (NYSE:CDE) today made the following statement regarding Wheaton River Minerals Ltd.’s (TSX:WRM, AMEX:WHT) comments today:

     “The combination of Coeur and Wheaton River is compelling and provides superior value – and the market agrees, based on the trading since our announcement,” said Dennis E. Wheeler, Chairman and Chief Executive Officer of Coeur. “For Wheaton River shareholders, this transaction offers higher total value, the only cash component, greater trading liquidity, and superior organic growth in the Americas. We have received a positive reception from Wheaton River shareholders and will continue to meet with them to inform them of our proposal.

     “We are continuing to pursue this as a friendly transaction and we have offered to meet with the Wheaton River Board to discuss our premium offer and respond to any questions they may have. We are surprised and disappointed that Wheaton River’s Board has made a recommendation to its shareholders without conducting any due diligence on Coeur or its properties. While we are disappointed that Wheaton River’s Board has decided to proceed with a transaction that provides its shareholders with significantly less value than Coeur’s offer, Wheaton River shareholders will have the opportunity to make their own decision at their shareholder meeting on June 8, 2004,” Mr. Wheeler added.

     “On January 1, 2004, Coeur completed its restructuring. We eliminated C$394 (US$284) million of high interest debt, and Coeur today is a company with cash of C$322 (US$235) million and no net debt. The market has recognized our successful transformation making Coeur’s shares among the best performing in the market place; and Coeur’s past losses are no longer relevant,” Mr. Wheeler concluded.

     In its offer to Wheaton River, Coeur provided a point-by-point comparison of Coeur’s offer with the pending IAMGOLD transaction. The comparison clearly demonstrates the superiority of the Coeur offer, and is repeated here:
