Pan american silvers huaron mine on strike
Vancouver, B.C.

- April 13, 2010 - Pan American Silver Corp.

("Pan American" or the "Company"), (NASDAQ: PAAS; TSX: PAA) today announced that an illegal strike declared by the union of mine workers has resulted in a work stoppage at the Companys Huaron mine in Peru.

The illegal strike started on Saturday April 10, 2010 and all production activities at the mine have now been shut down.


The union is disputing the amount of the 2009 workers profit-sharing payment.

Huarons profits in 2009 and the workers share were negatively affected by the economic downturn in the first half of last year.

In addition, there was a negative impact on profits due to the, as yet unrecovered amounts owed to the Company by the Doe Run Peru smelter which was forced to close in the first quarter of 2009 and has yet to reopen.


Profit sharing concerns and related work stoppages are not isolated to the Huaron mine and have arisen at a number of other operations in Peru in recent weeks.

At this time, the Huaron mine is the only Pan American mine affected by the strike.

The Company is continuing its efforts to resolve the dispute with the Huaron union.
Depending on its duration, the strike could have a negative impact on the annual production forecast for the Huaron mine.
