                                                           For Immediate Release

           PAN AMERICAN TO DEVELOP THE MANATIAL ESPEJO SILVER PROJECT
                  (all amounts in $US unless otherwise stated)

Vancouver, Canada - Pan American Silver Corp. (PAAS: NASDAQ; PAA: TSX) is
pleased to announce that it has received approval from the Province of Santa
Cruz Argentina for the Environmental Impact Statement on its 100% owned
Manantial Espejo silver project and plans to immediately proceed with the
development and construction of the mine. The Company also signed an agreement
with the Federal Government of Argentina and the Province of Santa Cruz to bring
grid electrical power to the town of Gobernador Gregores with a sub-connection
to Manantial Espejo.

The recently completed feasibility study for Manantial Espejo estimates that the
project will produce on average 4.3 million ounces of silver and 62,000 ounce of
gold annually over a mine life of 8.5 years, based on current proven and
probable reserves. Capital costs for the project are expected to be $112.3
million including working capital and normal construction contingencies, plus
$18.1 million in Argentine Value Added Tax which will be refundable once the
mine is in production.

At the feasibility study price assumptions of US$6.75 per ounce for silver and
US$475 per ounce for gold, the mine will generate an undiscounted after tax net
present value of $72.6 million, an internal rate of return of 12% and a capital
payback of 3.5 years. Average life of mine cash costs will be $0.02 per ounce,
net of gold byproduct credits. At today's prices the undiscounted after tax net
present value of the project would be $169 million, the internal rate of return
increases to 25% and the capital payback period would be approximately 2.3
years.

Basic engineering for the project has been initiated and construction is
expected to take 18-20 months. Existing mineral reserves are concentrated in
four zones: the Maria, Karina Union, Melissa and Concepcion deposits which will
be developed using both open pit and underground mining methods. Silver and gold
recovery will be by conventional milling and leaching at a rate of 2,000 tonnes
per day. The feasibility study estimates that the recovery rates for silver and
gold will be 93% and 94%, respectively. Pan American is currently exploring
financing options for the project.

According to Pan American Chairman Ross Beaty; "Development of 100% of Manantial
Espejo secures Pan American's future as the world's number one primary silver
producer. Together with this project, the completion of our new Alamo Dorado
mine in the fourth quarter of this year and the expansion of our San Vicente and
Morococha mines, we expect to double our current annual production to more than
25 million ounces of silver by the end of 2008. We have received great
co-operation from the Argentine government at the federal and provincial levels,
and particularly from the local community of Gobernador Gregores. I look forward
to a successful mine development at Manantial Espejo for the benefit of
Argentina, the local community and of course our shareholders."
