Goldcorp/Wheaton Transaction Recommended by Proxy Advisory Firm

    News Editors

    VANCOUVER, British Columbia--(BUSINESS WIRE)--Feb. 4, 2005--Wheaton River Minerals Ltd. (TSX:WRM) (AMEX:WHT) announced that Glass, Lewis & Co, a U.S. independent proxy advisory firm, has recommended that its clients who hold Goldcorp shares vote for Goldcorp's proposed merger with Wheaton River at Goldcorp's shareholders meeting to be held on February 10, 2005.

    The Glass, Lewis Report summarizes its conclusions as follows: "In our opinion, the Wheaton transaction creates substantial shareholder value; indeed, we believe that Glamis' own slides - purporting to demonstrate that the Wheaton deal is destructive of shareholder value - themselves demonstrate rather the benefits of the deal. The Glamis acquisition proposal, by contrast, is approximately value neutral to Goldcorp shareholders. We therefore recommend that shareholders vote FOR (the Goldcorp/ Wheaton transaction)."

    Ian Telfer, Chairman and CEO of Wheaton River, said "We are pleased that another independent proxy advisory firm has come out recommending the Goldcorp/Wheaton transaction. Glass, Lewis & Co's conclusions confirm our belief that the merger offers the best value and opportunity for shareholders of both Wheaton River and Goldcorp".

    The board of directors of Wheaton River continues to recommend that Wheaton River shareholders accept Goldcorp's offer and tender their common shares to Goldcorp's offer. There is no risk for Wheaton River shareholders in tendering their shares prior to the Goldcorp shareholders meeting, as tendered shares will be returned in the event that Goldcorp's offer does not proceed.

    Glass, Lewis & Co. is an analytical research firm that uses proprietary research and extensive analysis to objectively evaluate the corporate integrity and financial trans-parency of public companies.
