Goldcorp Inc. and Wheaton River Minerals Ltd.: Goldcorp Acquires Berme

    News Editors

    VANCOUVER, British Columbia--(BUSINESS WIRE)--March 22, 2005--Goldcorp Inc. (TSX:G)(NYSE:GG), and Wheaton River Minerals Ltd. (TSX:WRM)(AMEX:WHT) (together "Goldcorp"), are pleased to announce the acquisition by their Mexican operating arm, Luismin, of the 2.4 million ounce Bermejal Gold Deposit in Mexico for cash consideration of US$70 million. Closing of the acquisition, from Minera El Bermejal, S. de R.L. de C.V. ("Minera Bermejal"), a joint venture of Industrias Penoles S.A. de C.V. ("Penoles") and Newmont Mining Corporation ("Newmont"), is expected by March 31, 2005.

    In order to finance the acquisition, Goldcorp will sell its inventory of gold bullion early in the second quarter of 2005. Furthermore, given Goldcorp's intent to continue to grow by way of accretive acquisitions, the Company intends to discontinue its previous practice of stockpiling one third of its production from the Red Lake Mine.

    Ian Telfer, President and Chief Executive Officer of Goldcorp, said, "This transaction is a key step in consolidating control of the Guerrero Gold Belt, a significant part of our growth strategy in Mexico. This purchase increases Goldcorp's current measured and indicated mineral resources in this district to nearly 6 million ounces of gold. The immediate proximity to our Los Filos Gold Deposit will allow the use of a joint processing facility for ore from both deposits, which will provide considerable economies of scale. The acquisition of Bermejal will turn our Los Filos project into the largest gold mining operation in Mexico, with average annual production expected to exceed 300,000 ounces.

    By financing this acquisition through the sale of our gold bullion inventory, we are converting 240,000 ounces of gold in the bank vault into 2.4 million ounces of gold in the ground. This is accretive by any measure."

    The Bermejal Gold Deposit is located 2 kilometres south of Goldcorp's Los Filos Gold Deposit, where feasibility studies are nearing completion. Testwork completed by both Minera Bermejal and Goldcorp during due diligence indicates run of mine heap leaching is the preferred processing method.

    With the acquisition, the main design effect on the Los Filos feasibility study will be a change in the proposed heap leach pad location to a more central location in order to provide enough capacity to process material from both open pittable deposits. Geotechnical and design studies have already commenced on the new pad location. With the majority of Bermejal ore run of mine heap leached, the already designed Los Filos crushing / agglomeration plant will not change in scope.

    Goldcorp plans to immediately commence further metallurgical, geotechnical, and engineering studies towards developing both Bermejal and Los Filos into one comprehensive mining operation.

    Reserves and Resources for Goldcorp's interests in the Guerrero Gold Belt are reported as follows;
