         schedule for early 2011.

     "Over the course of its construction and production ramp-up, Penasquito
has achieved every significant operational milestone on schedule, culminating
in today's declaration of commercial production," said Steve Reid, Executive
Vice President and Chief Operating Officer of Goldcorp. "Concentrates from
both process lines are now being routinely produced and sold as expected to
our smelter partners around the world. As this successful ramp-up continues,
our shareholders are well-positioned to reap the benefits in the form of
rapidly accelerating cash flows over the next several years.
     "The ability of our mine development team to complete this important
project on schedule and on budget illustrates the skills and expertise of our
mine-building team. We will apply these skills to our industry-leading suite
of growth projects which include Cochenour at Red Lake, Eleonore in Quebec, El
Morro in Chile, the Noche Buena and Camino Rojo satellite projects near
Penasquito and the recently-acquired Cerro Negro project in Argentina."
     Penasquito has a designed processing capacity of 130,000 tonnes per day,
consisting of two 50,000 tonne per day capacity sulphide processing lines
(Lines 1 and 2) and the 30,000 tonne per day capacity HPGR circuit. Line 1 is
consistently operating at design capacity and Line 2 is ramping up, already
reaching a peak daily throughput of 56,170 tonnes. Construction of the HPGR
circuit is well advanced, with commissioning due to commence in early October.
     Gold production is expected to ramp up throughout the remainder of 2010,
on track with issued guidance of 180,000 ounces. Penasquito is expected to
reach full design capacity in early 2011. Over its 23-year mine life, the
operation is expected to produce an annual average of 500,000 ounces of gold,
28 million ounces of silver, 450 million pounds of zinc, and 200 million
pounds of lead at net negative by-product cash costs.
     The Company continues to advance a number of initiatives to further
enhance the economics at Penasquito and develop exploration projects in the
district. The potential for significant supplemental gold production from the
Noche Buena satellite oxide deposit continues to grow, with a scoping study
expected to be completed by year-end. Permitting and ore body analysis
continues at Camino Rojo, another potential source of satellite gold
production. Deep drilling at Penasquito has recently intersected a new
sulphide manto deposit on the east side of the Penasco pit that demonstrates
similar characteristics to existing high grade manto resources. The results
continue to support the potential for a concurrent high grade underground
operation with an opportunity to further supplement core Penasquito
production. Progress has continued on the in-pit crushing and conveying (IPCC)
system that is expected to provide significant capital and operating savings
compared to conventional truck-only haulage, with completion remaining on
track for 2013.
     Goldcorp is North America's fastest growing senior gold producer. Its
low-cost gold production is located in safe jurisdictions in the Americas and
remains 100% unhedged.
