ITEM 1.           Name and Address of Company

                  Pan American Silver Corp. (the "Company")
                  1500 - 625 Howe Street
                  Vancouver, British Columbia  V6C 2T6

ITEM 2.           Date of Material Change

                  March 23, 2006

ITEM 3.           News Release

                  A press release was issued by the Company on March 23, 2006 at
                  Vancouver, British Columbia and distributed through the
                  facilities of Canada NewsWire.

ITEM 4.           Summary of Material Change

                  The Company announced that it has received clearance from the
                  Province of Santa Cruz Argentina for the Environmental Impact
                  Assessment on its 100% owned Manantial Espejo silver project
                  and plans to immediately proceed with the development and
                  construction of the mine.

ITEM 5.           Full Description of Material Change

                  The Company announced that it has received clearance from the
                  Province of Santa Cruz Argentina for the Environmental Impact
                  Assessment on its 100% owned Manantial Espejo silver project
                  and plans to immediately proceed with the development and
                  construction of the mine. In addition, 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. 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 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. Mineralization
                  is 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. The Company is currently exploring
                  financing options for the project.
