West Timmins Mining and Trelawney Resources Expand La Bufa Copper-Gold Project, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 4, 2007) - West Timmins Mining Inc. (" West Timmins") (TSX:WTM), on behalf of its wholly owned Mexican subsidiary Minera Golondrina S. De R.L. De C.V., and Trelawney Resources Inc. ("Trelawney") (TSX VENTURE:TRR) announced today that they have jointly entered into a Letter of Intent to acquire a combined 100% interest in the La Bufa Azteca Property. The 135 square kilometre La Bufa Azteca Property adjoins West Timmins La Bufa Property where Trelawney can earn a 50% interest as announced November 26, 2007 (see NR07-39). The La Bufa Azteca Property hosts the former producing Caballero Azteca gold zone and a number of similar copper-gold occurrences. The La Bufa area is located in south-western Chihuahua State, Mexico, 25 kilometres east of Goldcorp's El Sauzal Gold Mine and 75 kilometres east of West Timmins' Montana de Oro Project.

Historically reported sampling of the Caballero Azteca gold zone by Francisco Gold (now Goldcorp) and COREMI (the Mexican Geological Survey) returned between 0.30 and 50.00 g/t gold and 6.65 to 29.70 g/t silver from grab samples of both in-situ and dump material. Recent chip sampling by the property vendor of silicified breccias in the walls of the Caballero Azteca gold zone returned 4.04 g/t gold over 6.00 metres. The Caballero Azteca gold zone is interpreted to represent the upper, gold-rich portion of a vertically zoned copper-gold system similar to the Carmen Mine on the adjacent La Bufa Property. Historical records indicate that the Carmen Mine produced approximately 1 mT of copper and gold ore at average grades of 2.50% copper, 2.90 g/t gold and 2.80 g/t silver.

"We are very pleased to be able to significantly expand our holdings in the La Bufa area at minimal cost to the Company," said Darin Wagner, President and CEO of West Timmins Mining. "The similarities between a number of the mineralized zones on the newly acquired property and the historically productive Carmen Mine are numerous and indicate the presence of a large copper-gold system."

Under the terms of the Letter of Intent with vendor Minera Cascabel S.A de C.V. ("Cascabel"), West Timmins and Trelawney will have the right to earn a 100% interest in the La Bufa Azteca Property by making a series of cash payments and issuing payments of common shares over four years, and annually completing twice the minimum annual work expenditures on the Property required under Mexican mining legislation. West Timmins may vest its 50% interest in the Property by making cash payments totalling CDN$135,000 in years three and four of the agreement and issuing 225,000 commons shares over four years. West Timmins will be the operator of the La Bufa Project.

Trelawney will fund the initial US$1,000,000 in exploration expenditures on the combined La Bufa and La Bufa Azteca Property position (the "La Bufa Project"). Upon successful vesting of their respective 50% interests West Timmins and Trelawney will grant to Cascabel a 1% NSR royalty on base metal and a 2% NSR royalty on precious metal production from the La Bufa Azteca Property. West Timmins will also, subject to successful vesting of its La Bufa Azteca interest, grant to Cascabel a 1% NSR royalty on base and precious metal production from its adjacent La Bufa Property. The Letter of Intent and contemplated option agreement are subject to final board and regulatory approvals.
