Toronto Stock Exchange: G New York Stock Exchange: GG Goldcorp Announces Expansion Of Cerro Negro Project; Proven And Probable Gold Reserves Double VANCOUVER, BRITISH COLUMBIA, April 5, 2011 � GOLDCORP INC.

(TSX: G, NYSE: GG) today announced the results of a feasibility study update for the Company�s recently acquired Cerro Negro project in the Santa Cruz province of Argentina.� Highlights Average annual gold production during first 5 years of approximately 550,000 ounces. Average cash costs of less than $200 per ounce of gold during first 5 years. Mine life of approximately 12 years; initial gold production planned for mid-2013. Throughput of 4,000 tonnes per day. Total capital cost of $750 million to full production. Total proven and probable gold reserves increase 100% to 4.3 million ounces. Vein extensions and new vein targets support strong potential for additional reserve growth in 2011.
�The positive results in this feasibility study confirm our expectations that Cerro Negro will contribute tremendous value for shareholders as Goldcorp�s next cornerstone gold mine,� said Chuck Jeannes, Goldcorp President and Chief Executive Officer.��Capital cost estimates reflect more than a doubling of throughput, and the straightforward nature of the project design should result in a smooth construction period toward first gold production in just over two years.�This is an extremely robust project as now configured; however, with all of the identified veins remaining open and numerous additional veins already identified, we are excited by the potential for future expansion of gold reserves and near-term upside to the production profile.�Cerro Negro will be a key driver of Goldcorp�s peer-leading low cash cost profile and 60% gold production growth over the next five years.� Recent Vein Discoveries Drive Higher Throughput The new development plan details more than doubling the plant throughput to 4,000 tonnes per day, contributing to an average of 550,000 ounces of gold production per year over the first five full years.�Average cash costs during the first five years of production are expected to be less than $200 per ounce of gold.

Over the full 12 year mine life, based only on existing reserves, annual production is expected to average 340,000 ounces per year at cash costs of approximately $290 per ounce.

The mining of multiple veins creates significant flexibility for optimization of the mine plan as additional reserves are developed.

The increase in throughput and production from the original feasibility study is facilitated by the simultaneous mining of multiple, near-surface veins.�The six currently identified sources of gold reserves (Eureka, Mariana Central, Mariana Norte, San Marcos, Bajo Negro and Vein Zone) are in some cases physically separated by several kilometers.�The Vein Zone is planned as an open pit and each of the other areas are underground deposits to be accessed by separate declines from the surface.�The Eureka, Mariana Central and Mariana Norte veins will comprise the initial sources of ore production.�Development of the decline at the Eureka vein has already been advanced to more than 900 metres in length.

The declines at Mariana Central and Mariana Norte are expected to commence in the fourth quarter of 2011 following the issuance of necessary permits.

Total capital expenditures to first production in mid-2013 are expected to be approximately $750 million, including $130 million in 2011.

This amount includes approximately $500 million of direct costs for the expanded mining, process facilities and infrastructure, with the remainder in indirect costs including EPCM (Engineering, Procurement and Construction Management), owner�s costs and contingency.

Several important milestones have already been achieved since acquiring the Cerro Negro project.�In December 2010, the Environmental Impact Assessment permit was received which enabled construction on the project to begin.

Site access work is currently underway, the camp is being expanded, geotechnical drilling in the tailings and plant facilities is progressing and the powerline design and routing studies continue.

With the completion of the updated feasibility study, an update to pertinent parts of the Environmental Impact Assessment will now be presented to appropriate authorities.

Exploration to Accelerate Exploration drilling is ramping up to a total of 10 drill rigs on site in the second quarter with an updated budget of approximately $19 million for 2011.�The immediate focus of drilling will be on expansion of the Eureka, Mariana Central and Mariana Norte veins.�Reserve additions from these three veins have the potential to augment the near term production profile at Cerro Negro.

An additional near term focus of exploration will be on testing several new veins with known gold mineralization on the western portion of the property.

Proven and Probable Gold Reserves Double On February 9th 2011, Goldcorp announced a near-doubling of total gold resources at Cerro Negro.

Following the results of the feasibility study, the total proven and probable reserves have grown by more than 100% to 4.3 million ounces as shown in Table 1, resulting in a net addition of 2.2 million ounces to Goldcorp�s total proven and probable reserves, now at 62.3 million ounces.�A total of 36.2 million silver ounces have also been added to proven and probable reserves.
