Los Filos Gold Project Feasibility Study

05/17/2005

Vancouver, British Columbia: May 17, 2005 – Goldcorp Inc. (TSX: G; NYSE: GG) is pleased to announce that the stand alone Los Filos feasibility study has been completed, however, with the recent acquisition of the Bermejal gold deposit new studies are underway focusing on the integration of the two deposits. Final results on the stand alone Los Filos feasibility study are summarized as follows;

Los Filos Mineable Reserves		Tonnage (million tonnes)	Grade (grams Au/tonne)	Contained Gold (million ounces)
	Proven	18.33	0.85	0.50
	Probable	45.57	1.05	1.54
	Proven and Probable	63.90	0.99	2.04

Los Filos Mineral Reserves		Tonnage (million tonnes)	Grade (grams Au/tonne)	Contained Gold (million ounces)
	Measured	2.34	0.50	0.04
	Indicated	21.97	0.62	0.44
	Measured and Indicated	24.31	0.62	0.48
	Inferred	11.26	0.7	0.26

Minimal inferred resources were also contained within the design open pit.

The Los Filos deposit will be developed as an open pit heap leach operation, with two different methods of ore processing. Higher grade materials will be crushed to ¾” and agglomerated before being conveyor stacked and heap leached. Lower grade materials will be truck hauled from the open pit to the leach pad and run-of-mine heap leached. The recovered solution will be treated to produce a final dore product on site. The entire district has ready access to a paved highway system, water supplies, electrical power and nearby towns with a supply of skilled local labour. Mining has always been an important part of the culture in the area, and strong support for the Los Filos development has been received from the local communities and government agencies. As announced on March 31, 2005, Goldcorp acquired the Bermejal gold deposit, with studies now underway to combine the Los Filos and Bermejal deposits and fully optimize the potential economies of scale. As a result, a feasibility study combining the two deposits is expected to be completed in the 4^th quarter of 2005. Construction is already underway on some of the primary infrastructure and this work will be utilized in the mining of the combined deposits. Metallurgical testing for Bermejal together with geotechnical testing and design work for the revised and now centrally located heap leach pad will be carried out in the months ahead. With these delays, gold production is now expected to commence in late 2006. In order to reflect some successful step-out drilling at the northern boundary of the deposit, a resource and reserve update on Los Filos will also be completed during the second half of 2005 and incorporated into the comprehensive feasibility study. Goldcorp is 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 over 1.6 million ounces. Goldcorp has a strong balance sheet with approximately US$450 million in cash and equivalents, and no debt. Notes:

All Mineral Reserves and Mineral Resources have been calculated as of May 10, 2004, and are reported within the resource model completed by Snowden Mineral Consultants for the December 31, 2004 mineral resource statement, in accordance with the standards of the Canadian Institute of Mining, Metallurgy and Petroleum and National Instrument 43-101.
All Mineral Resources are exclusive of Mineral Reserves.
Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability.
A gold price of US$ 400 per ounce was used.
Mike Hester, P.E. of Independent Mining Consultants, Tucson is the Qualified Person for the feasibility study as defined by the National Instrument 43-101.
Neil Burns, P.Geo. of Snowden Mining Consultants Inc., Vancouver is the Qualified Person for the Mineral Resource estimates. Mineral Resources are reported within an optimized pit shell but outside the design open pit.
