WHEATON ACHIEVES RECORD

RESERVE / RESOURCE LEVELS

Vancouver, BC - Wheaton River Minerals Ltd. (“Wheaton”) (TSX: WRM; AMEX: WHT), recently acquired by Goldcorp Inc (TSX: G; NYSE GG), is pleased to report record levels of gold reserves and resources as of December 31, 2004, summarized as follows:

Proven and Probable gold reserves have increased to 5.1 million ounces;

Measured and Indicated resources have increased to 3.7 million ounces; and

Inferred resources have increased to 5.1 million ounces.

Ian Telfer, Chairman & Chief Executive Officer of the Company said: “Nearly one million gold ounces were added to the reserve base during 2004, almost double the year’s production of 513,000 ounces. Wheaton has also exceeded 5 million ounces of Proven and Probable gold reserves for the first time in company history. When you combine this organic growth in reserves and resources with our record gold production and cost achievements of 2004, the strength of our operating team stands out.”

Data shown is Wheaton River’s share of reserves and resources.

All Mineral Resources are exclusive of Mineral Reserves.

Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability.

Qualified Persons for the Mineral Reserve and Mineral Resource estimates as defined by the National Instrument 43-101 are as follows:

Luismin - San Dimas and San Martin reserves and resources

Reynaldo Rivera, AusIMM, Luismin S.A. de C.V.

Luismin – Nukay reserves and resources

Gary Giroux. P.Eng., Micon Consultants

Los Filos resources

Neil Burns, P.Geo., Snowden Mineral Industry Consultants

El Limon resources

6. Mineral Reserves and Mineral Resources are estimated using appropriate recovery rates and commodity prices as follows;

San Dimas, San Martin, Nukay, Peak, Amapari - US$ 375 per ounce of gold, US$ 5.50 per ounce of silver (where applicable), and US$ 0.95 per pound of copper (where applicable)

Alumbrera reserves - US$ 350 per ounce of gold, US$ 0.90 per pound of copper

Los Filos, El Limon, Alumbrera resources – wholly contained within an optimization shell defined by using US$ 400 per ounce of gold and US$ 1.00 per pound of copper (where applicable)

Reserve and Resource Growth

Luismin

For the first time ever the prolific San Dimas camp has exceeded one million gold equivalent ounces in proven and probable reserves. Surface and underground drilling continues to define a high grade east-west regional trend through the centre of this district, and the new tunnel to access these vein systems at depth is advancing ahead of schedule. At the San Martin operation, development of the Cuerpo 31 orebody is progressing on schedule and first ore was delivered from this orebody during 2004. Drilling from both surface and underground continues to define and expand the northern and depth extents of this orebody.

Los Filos

The December 31, 2004 resource is reported within a US$ 400 gold optimized pit shell, and includes crush/leach resources of 51 million measured and indicated tonnes grading 1.28 grams of gold per tonne for a total of 2.1 million ounces. In addition, metallurgical testing during the year has shown that a large amount of lower grade material previously defined as uneconomic can be profitably run-of-mine leached. Since acquisition, drilling and metallurgical improvements have increased the global measured and indicated resource ounces at Los Filos by 41%.

El Limon

During 2004 drilling was focused on defining the limits of the Guajes West orebody and testing extensions to the south of the Limon Sur deposit. Over the year, inferred resources at this deposit were increased by 63% to over 3 million ounces, all contained within a US$ 400 gold pit optimization shell. An infill drilling campaign is expected to begin during 2005.

Peak

Since the acquisition of Peak in mid 2003, gold ounces contained in resources have now more than doubled. 2005 drilling will focus on advancing these resource ounces into the reserve base.

Alumbrera

A significant drilling program was conducted during 2004, adding more than two years of operating life to this world class operation. At the end of 2004, another 30 million tonnes were added as measured and indicated resources.

Amapari

Since acquisition in January 2004 the Company has conducted a successful infill and step-out drilling program. Studies have demonstrated that open pit mining of a portion of the sulphide reserves is feasible, and the consequent decrease in operating costs per tonne has resulted in a significant amount of lower grade material becoming economically mineable. Cash costs are expected to remain in line with previous projections of US$ 137 per ounces of gold. Production is expected to commence in Q3 2005.

In February 2005, Goldcorp announced that it’s offer for Wheaton River Minerals was successful and this merger is expected to be finalized in April 2005. The combined company, which will continue as Goldcorp, creates the world’s lowest cost, million ounce gold producer, with 2005 gold production expected to exceed 1.1 million ounces of gold at a cash cost of less than US$60 per ounce. By 2007, gold production is expected to grow to 1.5 million ounces with commencement of operation at Los Filos and Amapari and the expansion at Red Lake Mine. The combined company will have a strong balance sheet with over $500 million in cash and gold bullion, and no debt.
