STP Southern Pacific Resource Corp.

Southern Pacific Resource Corp. ("Southern Pacific" or the "Company") (TSX VENTURE: STP) is pleased to announce that it has closed the acquisition of Bounty Developments Ltd.'s 20% working interest in 59 sections of land in McKay, Alberta. The acquisition gives Southern Pacific an undivided 100% working interest in all of its McKay lands, including the 10.5-section STP-McKay Steam-Assisted Gravity Drainage ("SAGD") project 45 km northwest of Fort McMurray. As part of the agreement, first announced on March 19, 2010, Southern Pacific has also purchased a 20% working interest in 32 sections of land at Ells River adjacent to and near Southern Pacific's MacKenzie block (the "Acquisition").

The entire package of reserves, resources and undeveloped land was closed on June 1, 2010 for a total of $33.0 million, consisting of 20% equity ($6.6 million) and 80% cash ($26.4 million). The 20% equity will be issued as common shares of the Company at a price equivalent to the applicable 10-day volume weighted average trading price of the shares, which equals approximately 6.47 million shares at a price of $1.02 per share. All of the shares issued in connection with the Acquisition are subject to a four-month hold period in accordance with applicable securities laws. Following the completion of the Acquisition, the Company has 316.2 million common shares issued and outstanding.

Southern Pacific's STP-McKay SAGD project is a 12,000 bbl/d in-situ thermal project that is in the application approval process. Southern Pacific submitted the application to Alberta Environment and the Alberta Energy Resources Conservation Board in May 2009 with approval expected by the end of August 2010. Construction of the project is expected to commence this fall immediately after regulatory approval is obtained.

As noted above, within the Acquisition Southern Pacific also acquired a 20% working interest in 32 sections of land at Ells River formerly operated by Patch International Ltd. Twelve sections of these lands are adjacent to Southern Pacific's 18-section MacKenzie block (100% working interest). These 12 sections have had coreholes drilled and contingent resources have been assigned by an independent reserves auditor. The acquired lands will allow additional proprietary technical data to be incorporated into the Company's records and facilitate lower cost exploration around its 100% working interest MacKenzie block, which has not yet been explored.

Southern Pacific is also pleased to announce that the Toronto Stock Exchange has approved the Company's application to graduate from the TSX Venture Exchange to the TSX. The Company's shares are expected to cease trading on the TSX Venture Exchange and begin trading on the TSX on June 3, 2010. The shares will continue to trade under the symbol STP.

"The TSX listing represents another milestone in our development as a Company," said Byron Lutes, President and CEO of Southern Pacific. "We expect the visibility and prestige of Canada's largest stock exchange to provide current and future shareholders with increased liquidity and to provide the Company with enhanced access to capital to facilitate our continued growth."

Readers' Advisory

Barrel of Oil Equivalent: Where amounts are expressed on a barrel of oil equivalent ("boe") basis, natural gas volumes have been converted to boe at a ratio of 6,000 cubic feet of natural gas to one barrel of oil equivalent. This conversion ratio is based upon an energy equivalent conversion method primarily applicable at the burner tip and does not represent value equivalence at the wellhead. Boe figures may be misleading, particularly if used in isolation.

Definitions

"Contingent Resources" means those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. Contingencies may include factors such as economic, legal, environmental, political, and regulatory matters or a lack of markets. It is also appropriate to classify as contingent resources the estimated discovered recoverable quantities associated with a project in the early evaluation stage.
