PRESS RELEASE

GOLDCORP BOARD REJECTS GLAMIS OFFER AS INADEQUATE
GOLDCORP SHAREHOLDERS GIVEN MORE TIME — URGED TO VOTE FOR WHEATON

Toronto, January 21, 2005 — GOLDCORP INC. (GG: NYSE; G: TSX) has announced that the Board of Directors recommends that Goldcorp shareholders (1) REJECT the unsolicited hostile take-over offer by Glamis Gold Ltd. for Goldcorp and (2) VOTE IN FAVOUR of the Wheaton River Minerals Ltd. transaction.

Upon finishing its independent review, the Board re-affirmed its original position that the Wheaton transaction is in the best interests of Goldcorp’s shareholders.

“The due diligence process undertaken by the Goldcorp Board and Special Committee once again demonstrates that Goldcorp’s Board is comprised of independent individuals with a commitment to continue to provide for the best interests of our shareholders. This is consistent with the highest degree of corporate governance and further validates the Goldcorp/Wheaton combination as the very best value for our shareholders. This is the right deal for Goldcorp,” said Rob McEwen, Goldcorp Chairman and CEO.

Rejection of Glamis Offer

The Board carefully reviewed and considered the Glamis offer and the recommendations of the Special Committee. The Special Committee recommended that the Board recommend that shareholders reject the Glamis offer and vote in favour of the Goldcorp/Wheaton combination. In forming those recommendations, the Special Committee, received, among other things, advice from the Special Committee’s financial and legal advisors, Morgan Stanley Canada Limited and Torys LLP, respectively, including a financial opinion from Morgan Stanley Canada Limited that the exchange ratio pursuant to the Glamis offer was inadequate from a financial point of view to holders of Goldcorp shares.

The Board unanimously recommends that Goldcorp shareholders vote in favour of the Goldcorp/Wheaton combination. The Board also recommends, with two abstentions, that Goldcorp shareholders reject the Glamis offer and not tender their shares to the Glamis offer. A Director’s Circular providing details of the recommendations will be mailed to shareholders shortly.

In making their determinations, the Special Committee and the Board carefully considered a number of factors and identified the following as being most relevant:

     Financial Terms

     Business Risk

     Management Quality

Goldcorp Shareholders Given More Time

CEO Rob McEwen also said that the decisions Goldcorp shareholders will be asked to make in the next few weeks will be of critical importance to the value of their investment in Goldcorp and he believes that it is important to provide sufficient time and information for investors to be as fully informed as possible in making their decisions.

The special meeting of shareholders scheduled for January 31, 2005 to authorize the issuance of common shares in connection with the offer for Wheaton has been rescheduled for February 10, 2005. This extension is being made to ensure Goldcorp shareholders have ample time to review all pertinent information.

The record date for the special meeting of shareholders will not change and all votes cast to-date will be counted towards the February 10, 2005 special meeting, subject to revocation rights. The deadline for receiving proxies is extended to February 8, 2005 at 9:00 a.m. (Toronto time). The meeting will be held at 9:00 a.m. (Toronto time) on February 10, 2005 at Le Royal Meridien King Edward Hotel (details to follow) in Toronto.
