Pacific Rim Receives NYSE Amex Notification

VANCOUVER, BRITISH COLUMBIA, Nov 12 (MARKET WIRE) --
Pacific Rim Mining Corp. ("Pacific Rim" or the "Company") (TSX: PMU)(NYSE
Amex: PMU) has received notice from the NYSE Amex LLC ("NYSE Amex" or the
"Exchange") that, based on their review of the Company's fiscal 2010
first quarter results, the Company is not in compliance with Section
1003(a)(iii) of the Company Guide, having at July 31, 2009 stockholders'
equity of less than $6,000,000 while sustaining losses from continuing
operations and net losses in its five most recent fiscal years.

In order to maintain listing of the Company's common shares on the NYSE
Amex, the Company must submit a plan to the Exchange by December 11, 2009
addressing how it intends to regain compliance with Section 1003(a)(iii)
by May 11, 2011.

The Company will submit a plan (the "Plan") before the deadline of
December 11, 2009. If the Exchange accepts the Plan, then the Company may
be able to continue its NYSE Amex listing during the Plan period, up to
May 11, 2011, during which time the Company will be subject to periodic
review to determine whether it is making progress consistent with the
Plan. If the Company fails to submit a Plan acceptable to the Exchange,
or even if accepted, if the Company is not in compliance with the
continued listing standards at the end of the Plan period or the Company
does not make progress consistent with the Plan during the period, then
the Exchange may initiate delisting proceedings.

"We intend to do everything in our power to rectify our non-compliance
issue and maintain our NYSE Amex listing," states Tom Shrake, President
and CEO of Pacific Rim. "Our current Exchange non-compliance is yet
another damage the Company has suffered due to the failure of the
Government of El Salvador to follow Salvadoran law and international law.
Our U.S. subsidiary, which holds our El Salvador assets, has filed a
claim against El Salvador under the Dominican Republic-Central
America-United States Free Trade Agreement and under El Salvador's
Investment Law, and this claim remains pending. We continue to seek a
resolution to the El Dorado permitting impasse and have been in regular
communication with the Government of El Salvador over the past several
months. We are hopeful that a resolution can be reached, and Technical
Secretary Alex de Segovia of the newly-elected Funes administration has
publicly stated the same. Upon resolution of the El Dorado permitting
issue, the Company intends to become an environmentally cutting-edge,
low-cost gold producer in El Salvador with significant exploration upside
in its numerous high-grade epithermal systems along the Central American
Mineral Belt."

The Company's common shares continue to trade on the NYSE Amex under the
symbol "PMU" but will shortly become subject to the trading symbol
extension "BC" to denote non-compliance with the Exchange's continued
listing standards. The Company's common shares also continue to be listed
on the Toronto Stock Exchange ("TSX") in Canada under the symbol "PMU"
and that listing is not expected to be affected by the NYSE Amex
notification.
