LOI On The Hog Ranch Property 

VANCOUVER, BC - Pacific Rim Mining Corp. has signed a Letter of Intent ("LOI") with ICN Resources Ltd. ("ICN") and Washoe Gold Inc. ("WGI") (collectively with the Company and PREx, the "Parties") to acquire a 65% interest in the Hog Ranch Property located in Washoe County, Nevada.

"The Hog Ranch Property offers an excellent opportunity for the discovery of high-grade gold mineralization in a pro-mining jurisdiction," said Tom Shrake, President and CEO of Pacific Rim. "We are extremely excited to have this opportunity to apply our unique technical perspective exploring the feeder zones of low-sulfidation epithermal gold systems, where we have had significant past successes. Hog Ranch has been historically mined for bulk mineable, near-surface, heap-leachable deposits. Our focus will be on Hog Ranch's high-grade underground deposit potential. Our exploration strategy is to seek out exploration projects with the best odds of success. We are thrilled to have identified another project that meets our high standards of above-average exploration potential combined with low environmental risk. We look forward to completing our due diligence and moving forward exploring Hog Ranch with an outstanding partner at our side." As per the LOI, the Parties intend to enter into a Definitive Agreement on or before June 1, 2011 (subject to approval of the board of directors of Pacific Rim and ICN, and regulatory approval, including the approval of the TSX and the TSX Venture Exchange), which will provide for the grant to PREx of an option to acquire a 65% interest (the "Interest") in the Hog Ranch Property through the expenditure of an aggregate of US$8 million in exploration expenditures and the issuance of an aggregate of 1 million common shares of Pacific Rim, with annual extensions dependent on results of our exploration, according to the following schedule. The company's address is 1050 - 625 Howe Street, Vancouver, BC V6C 2T6, (604) 689-1976, fax: (604) 689-1978, email: [email protected].
