Pacific Rim Mining Announces Head Office Cutbacks

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 18, 2008) - Pacific Rim Mining Corp. (TSX:PMU)(AMEX:PMU) ("Pacific Rim" or "the Company") has made additional cuts to its overhead by significantly reducing staffing levels in the Vancouver office including Peter Neilans, COO and April Hashimoto, CFO. These cuts are a response to difficult market conditions and ongoing delays in obtaining environmental and mining permits for the El Dorado project. Both Mr. Neilans and Ms. Hashimoto will continue their relationship with the Company on a consulting basis, with Ms. Hashimoto transitioning the Company to a contract accounting firm and Mr. Neilans managing the completion of the El Dorado feasibility study.

"We must preserve capital," states Tom Shrake, President and CEO. Both Pete and April have contributed greatly to the Company over the past several years and will continue to lend their expertise going forward. We thank them for their service to the Company. We are tightening our belt as necessary and remain focused on securing the permits required to develop El Dorado so that the value we have built in the project can be realized by our shareholders."
