GLASS LEWIS, INDEPENDENT VOTING ADVISORY FIRM, SUPPORTS
GOLDCORP/WHEATON

Toronto, February 4, 2005 — GOLDCORP INC. (GG: NYSE; G: TSX) today announced that Glass, Lewis & Co., a leading independent voting advisory firm in the U.S., recommended that its clients, including institutional investment firms, mutual funds and other fiduciaries VOTE FOR THE GOLDCORP/WHEATON TRANSACTION.

“We are very pleased that, after an independent and comprehensive review, Glass, Lewis has confirmed the benefits of the Goldcorp/Wheaton River transaction for Goldcorp shareholders,” said Rob McEwen, Goldcorp Chairman and CEO. “The Glass Lewis recommendation is in keeping with the opinion of our entire Board of Directors: Wheaton is the right deal for all Goldcorp shareholders. Our shareholders are smart, and have always sought value in their investments” added McEwen.

In making its recommendation, Glass, Lewis said,

“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 [Wheaton] deal.”*

In preparing its analysis, Glass Lewis also said that, “We also used Glamis’ own numbers to calculate an implied valuation for new Glamis”*...and concluded that:

“Given these analyses, we find it relatively easy to agree with the unanimous [Goldcorp] board recommendation: the Wheaton deal appears to offer Goldcorp shareholders substantial value, while the Glamis deal appears to be roughly a push...

‘Ultimately, we believe that this is a quantitative decision for Goldcorp shareholders. We believe there is more value in a Goldcorp — Wheaton transaction than in the Glamis — Goldcorp transaction.”

Goldcorp continues to urge its shareholders to VOTE FOR THE GOLDCORP/WHEATON TRANSACTION TODAY by signing, dating and returning the GREEN proxy or following the easy directions on the GREEN proxy to vote by telephone or Internet.

The special meeting of shareholders will be held February 10, 2005 at 9:00 a.m. Toronto time at the Windsor Ballroom, Le Royal Meridien King Edward Hotel, 37 King Street East, Toronto, Ontario, Canada. The deadline for receiving proxies is February 8, 2005 at 9:00 a.m. Toronto time.
