STP Southern Pacific Resource Corp.

Southern Pacific Resource Corp. ("Southern Pacific" or the "Company") (TSX VENTURE: STP) is pleased to announce that Mr. Ron Clarke has agreed to join the Company as Chief Operating Officer. This new position reflects Southern Pacific's advanced preparations for construction of its first oil sands project in McKay, Alberta. Project approval is expected by the end of the summer.

Mr. Clarke is a professional engineer who worked with Suncor Energy Inc. for more than 26 years in many facets of the bitumen, oil and natural gas business in Western Canada. He has spent the past three years working on Suncor's Firebag steam-assisted gravity drainage (SAGD) project, serving most recently as General Manager of the Firebag Asset Team. Mr. Clarke led the reservoir, geology and production engineering activities for both the base assets and the resource development strategy. Prior to this position, Mr. Clarke was the General Manager of Field Operations in Firebag where he led the well and gathering system operations of the commercial SAGD project. Mr. Clarke has held several other production and operational management positions over his career.

"We are extremely pleased to have someone with the background of Ron join our team," said Byron Lutes, President and CEO of the Company. "His experience in SAGD operations and management skills will be a valuable asset to Southern Pacific as we prepare to begin the construction and operation of our first SAGD project in the Athabasca oil sands, the STP-McKay Thermal Project." The Company expects approval of this project by the end of August 2010, with construction commencing in the fall of 2010.

In conjunction with Mr. Clarke's acceptance of employment, Southern Pacific has granted him 500,000 options to purchase shares of the Company at $1.02 per common share. This represents the closing price of Southern Pacific's shares on May 25, 2010. The options expire on May 25, 2015.
