WHEATON RIVER UNNECESSARILY PROCEEDS WITH
STOCKHOLDER MEETING DESPITE
COURT-ORDERED POSTPONEMENT OF IAMGOLD MEETING

WHEATON RIVER BOARD AGAIN DENIES STOCKHOLDERS ADDITIONAL
TIME TO CONSIDER COEUR’S SUPERIOR PROPOSAL

WHEATON RIVER ANNOUNCED VOTE COUNT IGNORES
TRUE STOCKHOLDER SENTIMENT

          Coeur d’Alene, Idaho, June 8, 2004 – Coeur d’Alene Mines Corporation (NYSE:CDE) today issued the following statement regarding today’s Special Meeting of Stockholders of Wheaton River Minerals Ltd. (TSX:WRM, AMEX:WHT):

          Dennis E. Wheeler, Chairman and Chief Executive Officer of Coeur, said, “We are astounded – as were Wheaton River stockholders present at the meeting – that Wheaton River’s Board unnecessarily proceeded with its Stockholder Meeting today despite today’s ruling by the Ontario Superior Court of Justice requiring IAMGOLD Corporation (TSX:IMG, AMEX:IAG) to postpone its Stockholder Meeting. Wheaton River ignored the efforts of many stockholders to cast votes against the IAMGOLD transaction, including Wheaton River’s largest institutional investor. Had those votes been counted, we believe the outcome of today’s meeting would have been reversed. Wheaton River chose to accept the affirmative vote of only about one-third of its total shares as representative of the sentiment of all of its stockholders.

          “The decision by the Ontario Court provided Wheaton River an opportunity to give its stockholders three full weeks of additional time to consider our increased — and superior — proposal. The Wheaton River Board might also have used this time to more fully review our proposal, instead of relying on its previous token review and hasty rejection. We do not understand why Wheaton River failed to take advantage of this additional time to consider our superior proposal and further do not understand why the meeting was conducted in a manner that ultimately resulted in a vote that ignores the true sentiment of Wheaton River stockholders.”

          “The effect of Wheaton River’s vote today, if allowed to stand, will be that IAMGOLD stockholders will have a 21-day option on the transaction, while Wheaton River stockholders will have no choice. We question the agenda of the Wheaton River Chairman and Board and their reasons for proceeding with today’s stockholder vote.

          “In today’s world of heightened corporate governance standards, we would be shocked to see a public company employ any procedures that would have the effect of disenfranchising stockholders. We call upon Wheaton River to immediately make available all of the voting records from today’s meeting.

          “Coeur intends to continue to pursue its superior merger proposal. We are carefully considering all of our options,” concluded Mr. Wheeler.

          CIBC World Markets Inc. is acting as financial advisor to Coeur. Gibson, Dunn & Crutcher LLP and Stikeman Elliott LLP are acting as legal counsel to Coeur.

          Coeur d’Alene Mines Corporation is the world’s largest primary silver producer, as well as a significant, low-cost producer of gold. The Company has mining interests in Nevada, Idaho, Alaska, Argentina, Chile and Bolivia.
