Pacific Rim Mining Corp.: Final Agreement on Andacollo
Sale Signed

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 30, 2005) - A formal
final agreement to sell Pacific Rim Mining Corp.'s ("Pacific Rim")
(TSX:PMU)(AMEX:PMU) wholly owned subsidiary DMC Cayman Inc. to a private
arms-length investor has been signed by both parties. The sale will
close within a further 30 days, pending regulatory and court approval.
DMC Cayman Inc.'s primary holding is the Andacollo gold mine in Chile,
which was officially shut down in December 2000 by Pacific Rim's
predecessor company Dayton Mining Corporation.

The purchaser has deposited in escrow both the US $900,000 payment
required upon signing of a final agreement under the terms of the
January 27, 2005 Letter of Intent, and the US $1 million payment due
June 1, 2005. This is in addition to a US $100,000 non-refundable down
payment deposited on January 27, 2005. All payments will be released to
Pacific Rim upon closing of the sale, expected on or before April 28,
2005. Future payments under the terms of the agreement include: US $1
million 18 months after closing; US $1 million 30 months after closing;
and, $1 million 36 months after closing.

"We are very pleased to have finalized the sale of our Andacollo asset
and look forward to closing the sale next month," states Tom Shrake,
CEO. "The sale proceeds will allow the Company to move forward
aggressively on a number of exploration and market education
initiatives. Our primary, short-term objectives are to expedite our
South Minita definition drilling program with the addition of two new
drill rigs. When completed, the South Minita drilling will lead to a
resource estimate for this new discovery, expected by mid-2005, to be
followed by a scoping study that will consider an expanded underground
operation based on the Minita deposit pre-feasibility results recently
reported. South Minita has the potential to significantly improve upon
the rate of return cited in the Minita pre-feasibility study by
expanding throughput, lowering costs and reducing the payback period. We
intend to meet these immediate objectives as quickly and efficiently as
