Vancouver, British Columbia: January 24, 2005 -- Wheaton River Minerals Ltd. (TSX:WRM) (AMEX:WHT) announced that the take-over bid made by Goldcorp Inc. for all of the common shares of Wheaton River on the basis of 0.25 of a Goldcorp common share for each Wheaton River common share has been extended to 5:00 p.m. (Vancouver time) on February 14, 2005.

The board of directors of Goldcorp has recommended that Goldcorp shareholders reject the unsolicted offer for Goldcorp by Glamis Gold Ltd. and that Goldcorp shareholders vote in favour of the Wheaton River transaction.  As described in Goldcorp's take-over bid circular mailed to Wheaton River shareholders in December 2004, Goldcorp's bid is conditional on Goldcorp shareholder approval.  The Goldcorp shareholders meeting is now scheduled for February 10, 2005.

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.

"We are pleased that Goldcorp has reaffirmed its commitment to create the world's lowest cost, million ounce gold producer with us and rejected the Glamis offer " said Ian Telfer, Chairman and Chief Executive Officer of Wheaton River.

New Goldcorp will:

• own the world class Red lake mine, one of the richest gold mines in the world;
  
  
• be NYSE and TSX listed, and have significantly enhanced trading liquidity;
  
  
• have a stronger financial position, providing a solid foundation for future growth;
  
  
• be an increasingly diversified leading gold producer with a balanced risk profile;
  
  
• have closely aligned core principles, values and strategic plans; and
  
  
• be guided by Wheaton River's highly experienced and proven management team, which will continue its growth plans.

Wheaton River has retained BMO Nesbitt Burns Inc. to act as an additional financial advisor in connection with Goldcorp's offer.
