Southwestern Resources Corp.: Positive Drill Results, Boka Gold Project, Yunnan Province, China

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Aug. 31, 2005) - Southwestern Resources Corp. (TSX:SWG) is pleased to announce that results have been received for a further 11 infill and step-out diamond drillholes from the Boka Project, located in Yunnan Province, China. Southwestern has a 90% interest in the Boka Gold Project which is comprised of 162 square kilometers of exploration concessions and mining leases located 265 kilometres by paved and gravel road north of the capital city of Kunming.

Highlights of the latest drill results from Boka 1 North and Boka 1 South include a 40.7 metre intersection of 3.7 grams per tonne gold in hole B05-102 and a 54.55 metre intersection of 3.6 grams per tonne gold in drillhole B05-105.

The latest drill results continue to define strong gold mineralization associated with quartz-carbonate-sulphide stockworks in carbonaceous slate, sandstone and conglomerate. As a result of a contractor change, there are presently six diamond drill rigs operating at Boka 1 with two additional rigs being mobilized. Drillholes B05-106 to B05-121, B05-123 and B05-126 have been completed and results are pending.

Results for the latest drillholes are listed in the following table. For drillhole locations, please see the Company's website at www.swgold.com.

The Company has commenced a pre-feasibility study on the Boka Project and has started environmental baseline studies, as well as step-out drilling and infill drilling to upgrade indicated/inferred resources to measured resources. Further metallurgical testing is also being carried out at SGS Lakefield Laboratories in Ontario.

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 metre, 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 using 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 Research 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 ALS Chemex in Vancouver, B.C. 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.
