Southwestern Resources Corp.: Drilling Continues to Expand Boka 1 Gold Zone Boka Gold Project, Yunnan Province, China

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - July 6, 2005) - Southwestern Resources Corp. (TSX:SWG) is pleased to report that assay results have been received for a further 13 diamond drill holes from the Boka 1 Gold Zone. The Company has a 90% interest in the Boka Gold Project located in northern Yunnan Province, China and comprised of 163 square kilometres of exploration permits and mining permits.

The latest drill results continue to define strong gold mineralization within the Boka 1 North and Boka 1 South gold zones. Highlights of the latest drill results include an intersection of 5.8 grams per tonne gold over a 63.15 metre intersection in hole B05-80.

Gold mineralization is associated with quartz carbonate and sulphide stockworks/veins in black carbonaceous shales, sandstone, and gabbro in shallow east dipping shear zones. The mineralization is stratiform in nature and remains open in all directions although the lack of any significant mineralization in holes B05-95 and B05-96 suggest a change in trend of mineralization from northwest to north.

There are presently nine diamond drill rigs operating at Boka 1 with the main objective to drill the Boka 1 Gold Zone on 100 metre by 50 metre centres.

Drill holes B05-91, B05-93, B05-94, B05-97 to B05-105 and B05-111 have been completed and assay results for these holes will be released when received.

Details of the latest drill results are listed in the following table. For drill hole locations and data please visit our website at www.swgold.com.

Quality Control

Southwestern has implemented a quality control program to ensure best practice in lithogeochemical sampling and analysis of soil, rock chips, trench, tunnel and drill core samples.

All drill core samples (approximately two metres one-half core composites) are shipped directly in security sealed bags to the SGS-China Laboratories preparation facility in Kunming. The entire composite is prepped to -10 mesh and a 500 gram split is sent to the SGS-CSTC Standards Technical Services Ltd. facility in Tianjan for conventional fire assay rising a 50 gram charge. Other elements are analyzed using ICP methods at the SGS Canada Inc. facilities in Mississauga.

Exploration samples (rockchip, soil, trench, tunnel) are shipped directly in security sealed bags to the assay laboratory of the Northwest Non-Ferrous Geology Reasearch Institute (ISO 9002) located in Xian, Shanxi Province, China and are digested in an aqua regia acid digestion and analyzed for gold and various other elements using atomic absorption.

The Company submits its own standards as a measure of the accuracy of the analysis. Field duplicates and pulp duplicates are routinely analyzed for precision. Routine assay checks from drill core are made at various North American laboratories. Sample results are received in batches and not as assays for an entire drill hole.

The exploration program is being carried out by John Zhang, Project Manager for Southwestern in China. John Paterson, President, Southwestern Resources Corp. and a member of AUSIMM is the qualified person as defined under National Instrument 43-101.

Southwestern Resources Corp. is exploring in several countries for precious and base metals. The Company has a number of significant projects including the Boka Gold Project in China with Team 209, the Liam Gold-Silver Project in Peru with Newmont Peru Limited, and the Antay Porphyry Copper-Gold Project in Peru with Anglo American Exploration Peru S.A., as well as the 100% owned Accha Zinc Project in Peru. The Company is also exploring for porphyry copper-gold in a large area of southwestern Yunnan Province, China under a Joint Venture with Newmont Overseas Exploration Limited.

Statements in this release that are forward-looking statements are subject to various risks and uncertainties concerning the specific factors disclosed under the heading "Risk Factors" and elsewhere in the Corporation's periodic filings with Canadian securities regulators.
