June 30, 2003


               PAN AMERICAN SILVER COMPLETES LA COLORADA EXPANSION
                       AHEAD OF SCHEDULE AND UNDER BUDGET
               (all figures in US dollars unless otherwise stated)

Vancouver, Canada - Pan American Silver Corp (NASDAQ - PAAS; TSX - PAA) is
pleased to announce the substantial completion of a major expansion at its La
Colorada silver mine in Mexico. The expansion is expected to increase the mine's
annual silver production from 0.7 million to 3.8 million ounces at a cash cost
of $2.65/oz. The $20 million expansion was completed ahead of schedule and 5%
under budget.

The expansion included the construction of a 600 tonne/day oxide mill added to
the existing 200 tonne/day sulphide mill. Commissioning of the new mill has been
in progress for several weeks and production is expected to reach design
capacity over the next few months. With more than 90% of its revenues derived
from silver, La Colorada is one of the purest silver mines in the world.

Pan American Silver owns and operates three large primary silver mines and a
small stockpile silver operation. The La Colorada expansion, coupled with
successful development of two of Pan American's other assets, the Alamo Dorado
and Manantial Espejo projects, should see Pan American's production double from
more than 10 million ounces in 2003 to 20 million ounces of silver in 2005.
