FAIRVEST RECOMMENDS GOLDCORP-WHEATON
Fairvest, Canada’s Leading Independent Proxy Firm And An Affiliate of Institutional Shareholder
Services (ISS), Recommends Voting For The Goldcorp-Wheaton Transaction

Toronto, January 26, 2005 — GOLDCORP INC. (GG: NYSE; G: TSX) today announced that Fairvest, Canada’s leading independent proxy firm and an affiliate of Institutional Shareholder Services (ISS), recommended that its clients, including institutional investment firms, mutual funds and other fiduciaries throughout Canada, the US and the world, VOTE FOR GOLDCORP’S PROPOSED TAKE-OVER OF WHEATON.

In making its recommendation, Fairvest said, “owing to lower downside risk in the long run and greater certainty with respect to the realisation of projected long term performance, we opt to back the Wheaton-Goldcorp transaction.” The Fairvest analysis continued to add that on the basis of financial ratios, Goldcorp-Wheaton would present an “attractive pick” for investors. Fairvest also said ”Clearly on an EPS level Wheaton-Goldcorp trumps Glamis-Goldcorp comfortably.”*

“We are very pleased that, after an independent and comprehensive review, Fairvest recognizes the advantages of the Goldcorp/Wheaton transaction for Goldcorp shareholders,” said Rob McEwen, Goldcorp Chairman and CEO. “The Fairvest recommendation to vote for the Wheaton transaction, is the same as the recommendation issued by the independent Special Committee of our Board of Directors after consultation with their financial advisor, Morgan Stanley Canada Limited. It is good to see Fairvest confirming what management and the Board have recommended in a unanimous vote for the Wheaton transaction. Wheaton is the right deal for all Goldcorp shareholders,” added McEwen.

Fairvest Corporation is a leading authority on proxy voting and corporate governance issues in Canada. Fairvest now serves 75 institutional investors on all proxy proposals with financial implications for approximately 2,200 Canadian Companies.

Goldcorp-Wheaton Benefits

The Goldcorp-Wheaton transaction offers shareholders:

Both Goldcorp and Wheaton’s management teams performed extensive due diligence during a two-week period that focused on the financial, legal and technical aspects of each company, including detailed site visits. Goldcorp was very pleased with the results of the due diligence, in particular, as it pertained to Wheaton’s underground operating experience and Wheaton’s track record of increasing production and lowering costs quarter after quarter.

The combination of Goldcorp and Wheaton brings together two of the most successful and entrepreneurial CEOs in the world of mining: “We have been fortunate to enjoy tremendous success growing Goldcorp organically through Red Lake, while Ian Telfer has made several highly accretive acquisitions resulting in returns to Wheaton’s shareholders of more than 200% in just two years. Both Ian and I share the same vision for the future of the ‘New Goldcorp’, we are focused on continuing to build per share value,” McEwen said.

THE CHOICE IS CLEAR: THE WHEATON TRANSACTION IS CLEARLY BETTER FOR GOLDCORP!

Goldcorp’s Red Lake Mine is the richest gold mine in the world. The Company is in excellent financial condition: has NO DEBT, a Large Treasury, positive Cash Flow and Earnings and pays a Dividend twelve times a year! GOLDCORP is UNHEDGED and currently withholds one-third of annual gold production in anticipation of higher gold prices. Goldcorp’s shares are listed on the New York and Toronto Stock Exchanges under the trading symbols of GG and G, respectively, and its options trade on the American Stock Exchange (AMEX), the Chicago Board of Options Exchange (CBOE) and the Pacific Stock Exchange (PCX) in the United States and on the Montreal Exchange (MX) in Canada.
