Vancouver, British Columbia: February 14, 2005 – Wheaton River Minerals Ltd. (TSX:WRM) (AMEX:WHT) announced today the following:

Goldcorp Offer is Successful

Goldcorp's offer for outstanding Wheaton common shares has been successfully completed.  As at 5:00 p.m. (Toronto time) on February 14, 2005, 396,603,552 Wheaton River common shares representing approximately 69% of the outstanding shares were tendered to the Goldcorp offer, more than satisfying the two-thirds minimum tender condition.  As all other conditions to the Goldcorp offer have been satisfied, Goldcorp has taken up all of the Wheaton River common shares tendered to the offer.  Payment for the Wheaton River common shares will be made on February 17, 2005 and registered shareholders will receive Goldcorp share certificates representing payment for their Wheaton River shares shortly thereafter.  Shareholders whose Wheaton River common shares are registered in the name of a nominee should contact their broker, bank, trust company or other nominee for payment confirmation. 

Goldcorp Offer Extended to Give Shareholders More Time to Tender

The Goldcorp offer has been extended to 5:00 p.m. (Toronto time) on February 28, 2005 in response to requests from Wheaton River shareholders who did not have sufficient time to tender their Wheaton River shares.

The period beginning at 5:00 p.m. (Vancouver time) on February 14, 2005 and ending at 5:00 p.m. (Toronto time) on February 28, 2005 is a “subsequent offering period” under Rule 14d-11 of the United States Securities Exchange Act of 1934, as amended.  During the subsequent offering period, Goldcorp  will accept for payment and promptly pay for Wheaton River common shares as they are tendered.  Wheaton River shareholders who tender Wheaton River shares during such period will be paid the same per share consideration of 0.25 of a Goldcorp share paid to Wheaton River shareholders who tendered their Wheaton River common shares prior to 5:00 p.m. (Vancouver time) on February 14, 2005.

Goldcorp to Acquire Remaining Shares by Mid-April

Wheaton River common shares not tendered by February 28, 2005 will be acquired by Goldcorp in mid-April 2005 for the same per share consideration of 0.25 of a Goldcorp share offered under the Goldcorp offer.  A special meeting of Wheaton River shareholders will be held on April 12, 2005 in Vancouver, B.C. to approve this transaction.   Goldcorp will own sufficient Wheaton River common shares to approve this acquisition assuming no additional Wheaton River shares are issued.  Wheaton River shares are expected to be delisted from the TSX and AMEX upon the completion of this transaction.

No Further Action Required by Wheaton River Warrantholders

Wheaton River warrantholders do not need to take any further action to benefit from the Goldcorp Offer.  Once all of the Wheaton River shares have been acquired by Goldcorp in mid-April, Wheaton River warrants will become exercisable for Goldcorp shares.  As a result:

• Each four regular warrants and each four Series A warrants of Wheaton River, which have an exercise price of C$1.65 and expire on May 30, 2007, will entitle warrantholders to purchase one Goldcorp share at an exercise price of C$6.60.
    
• Each four Series B warrants of Wheaton River, which have an exercise price of $3.10 and expire on August 25, 2008, will entitle warrantholders to purchase one Goldcorp share at an exercise price of $12.40.
  

For example, a warrantholder with 400 Wheaton River warrants which are exercisable for 400 Wheaton River shares at an exercise price of C$1.65 will be entitled to exercise those warrants for 100 Goldcorp shares at an exercise price of C$6.60 after the completion of the second step acquisition transaction.

Until then, Wheaton River warrants will continue to trade on the TSX and be exercisable for Wheaton River shares.
