Southwestern Resources Corp.: Drilling Continues to Expand Boka 1 Zone and Intersect High Grade Gold Mineralization Boka Gold Project, Yunnan Province, China

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 7, 2005) - Southwestern Resources Corp. (TSX:SWG) is pleased to announce that results have been received for a further 23 in-fill and step out drillholes from the Boka Gold Project located in Yunnan Province, China. Southwestern has a 90% interest in the Boka Gold Project, which is comprised of 153 square kilometres of exploration concessions and mining leases, located 265 kilometres by paved and gravel road north of the capital city of Kunming. The Company is also pleased to announce that regional exploration work in the southwest corner of the Project area has identified an extensive copper-gold zone hosted in limestones adjacent to active mining operations in the Dongchuan Copper Belt.

Highlights of the latest drill results from Boka 1 North and Boka 1 South include a 23.30 metre intersection of 6.3 grams per tonne gold in hole B05-108, a 99.7 metre intersection of 4.2 grams per tonne gold in hole B05-111 and a 27.10 metre intersection of 3.8 grams per tonne gold in hole B05-127. Several holes intersected high grade gold mineralization including a 7.8 metre intersection of 14.1 grams per tonne gold in hole B05-108, a 10.0 metre intersection of 20.6 grams per tonne gold in hole B05-111, a 5 metre intersection of 34.0 grams per tonne gold in hole B05-112, a 4.0 metre intersection of 21.7 grams per tonne gold in hole B05-114 and a 2.10 metre intersection of 17.3 grams per tonne gold in hole B05-117.

The latest drilling has also extended the mineralization at Boka 1 North downdip 400 metres in hole B05-122 and 450 metres downdip at Boka 1 South in hole B05-114.

At present, there are eight drill rigs operating on the Property. It is planned to continue the drilling at Boka 1 with five rigs, initiate grid drilling at Boka 7 with two rigs and start testing of the Boka 7 Lower Zone with one rig.

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

Regional Exploration

The Company has completed a detailed regional evaluation program in the southern area of the Project. As a result of this program, an extensive copper-gold zone located 100 metres north of the operating Dongchuan copper mine has been identified. The copper-gold zone is hosted by limestone and extends for 800 metres along strike and is up to 50 metres in width. Surface outcrop in this zone contains copper oxides. The zone is being trenched and sampled in detail to bring to the drilling stage.

Pre-feasibility Study

A pre-feasibility study has been initiated on Boka 1 and Boka 7 and environmental studies and logistical studies have commenced.

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 Project's qualified person as defined under National Instrument 43-101.

Corporate

The Company advises that its over-allotment option to the underwriters under its prospectus dated September 30, 2005, as amended, is terminated and therefore the Company's shares are no longer in distribution.

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.
