NYSE Amex Accepts Pacific Rim Mining's Compliance Plan

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 11, 2010) - Pacific Rim Mining Corp. ("Pacific Rim" or the "Company") (TSX:PMU)(NYSE Amex:PMU) received notice of acceptance by the NYSE Amex LLC ("NYSE Amex" or the "Exchange") of the Company's listing compliance plan (the "Plan"). The Plan was submitted to the NYSE Amex in response to notification from the Exchange in late November, 2009 of the Company's non-compliance with Section 1003(a)(iii) of the NYSE Amex Company Guide, having stockholders' equity of less than $6,000,000 at July 31, 2009, while sustaining losses from continuing operations and net losses in its five most recent fiscal years.

With the Exchange's acceptance of the Plan, the Company's NYSE Amex listing is expected to continue during the Plan period, up to May 11, 2011, subject to periodic review to determine whether the Company is making progress consistent with the Plan and conditions of NYSE Amex. If the Company is not in compliance with the continued listing standards at the end of the Plan period, or if the Company does not make progress consistent with the Plan during the period, then the Exchange may initiate delisting proceedings.

The Company's common shares continue to trade on the NYSE Amex under the symbol "PMU" with the trading symbol extension "BC" to denote non-compliance with the Exchange's continued listing standards while the Plan period is in effect. The Company's common shares also continue to be listed on the Toronto Stock Exchange ("TSX") in Canada under the symbol "PMU".
