NEWS RELEASE

SOUTHWESTERN RESOURCES APPOINTS INTERIM PRESIDENT AND CEO

July 4, 2007

Vancouver, BC – Southwestern Resources Corp. (SWG-TSX) (“Southwestern” or “the Company”) today named Timo Jauristo as interim President and CEO, effective immediately.

Mr. Jauristo is a geologist with more than 26 years experience in the mining industry. He joined Southwestern in 2005 as Vice President, Corporate Development and was named to the Board of Directors in 2006. Mr. Jauristo will continue to fulfill his responsibilities as President and CEO of Zincore Metals Inc., the Vancouver-based zinc company that was spun out of Southwestern in 2006.

As part of its ongoing governance practices, Southwestern’s Board has formed a Special Committee of independent Directors to identify and help the Board select a permanent President and CEO and review the reasons and practices that resulted in the delay of the Boka pre-feasibility report. The Company has also retained a leading global executive search firm to assist in identifying suitable CEO candidates.

On Mr. Jauristo’s appointment, Southwestern’s Chairman David Black said: “The Board is pleased Timo has accepted this responsibility. His expertise in geology and in-depth knowledge of the Company and its assets positions him well to lead the organization through this transition period. We will now turn our focus to the search process to ensure we find the best candidate to lead the Company through its next phase of growth.”
