WTM Reports Highest Grade, Widest Intercepts to Date from La Dura West Discovery

31.16 Metres Grading 6.05% Zinc, 0.94% Copper, 51.48 g/t Silver and 0.80 g/t Gold

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 28, 2007) - West Timmins Mining Inc. (TSX:WTM) announced today that drill hole LC07-15 has intersected 31.16 metres (102.23 feet) grading 6.05% zinc, 0.94% copper, 51.48 g/t silver and 0.80 g/t gold starting at a depth of only 44 metres below surface. These results are the highest grade, widest and deepest intercepts to date from the La Dura West Discovery which remains open down dip and along strike. The La Dura West Discovery is one of several zones of mineralization currently being drill tested on the Company's 100% owned Montana de Oro Project located in the Sierra Madre Belt, Mexico.

"The grade and thickness of the latest intercepts clearly warrant a significantly expanded drill program at La Dura West. When combined with the shallow depths and high value of the metal basket we are very excited by the potential for this discovery," said Darin Wagner, President and CEO of West Timmins Mining.

The zinc grade for hole LC07-15 is preliminary in nature as six samples, ranging from 0.30 to 0.60 metres in width, exceeded the maximum detection limit for fire assay of 30% zinc. Additional analysis are being undertaken to accurately determine the zinc content of these very high-grade intercepts and are expected to take 4-6 weeks to complete. Assay results from the lower 400 metres of hole LC07-15 remain pending. Cross sections and locations maps for the La Dura West Discovery are available on the Company's website at http://www.westtimminsmining.com/main/?laDura.

The La Dura West Discovery is one of a number of zones of mineralization related to a large, multi-stage intrusive system which can be traced over several kilometres within the Montana de Oro Project area. Drilling continues at La Dura West and on the nearby La Dura East zinc-lead-silver discovery.

The La Dura discoveries are located in the south-central portion of West Timmins 100% owned, 557 square kilometre Montana de Oro Project. The Montana de Oro Project sits at the heart of the Three States District, less than 50 kilometres from six new mines or mine development projects including Goldcorp's lowest cost gold producer - the El Sauzal deposit, Palmarejo Silver and Gold's Palmarejo-Trogan deposit and Pan American Silver's Alamo Dorado silver mine.

Quality Control and Assurance

Geochemical results reported herein are from halved drill core samples collected from the Company's Montana de Oro project. Core sampling is conducted on site by trained personnel and sealed samples are transported to ALS-Chemex's preparation facilities in Hermosillo, Mexico by employees of consulting firm Minera Cascabel S.A. de C. V. on behalf of West Timmins Mining. Samples were assayed for gold by standard fire assay-ICP finish with a 30 gram charge. Samples additionally underwent 34 element ICP-MS analysis. Silver, zinc, copper and lead values in excess of 100 ppm, 1%, 1% and 1% respectively were re-analyzed by fire assay. The remaining half of the drill core is stored in a secure facility on the project site. For quality control purposes blank and analytical control standards were inserted into the sample sequence at regular intervals. Mr. Darin Wagner (M.Sc., P.Geo), the Company's President, has acted as qualified person for this news release. The qualified person has visited the project site, reviewed the available technical information for the project and has verified that there were no discrepancies with the respect to the quality control samples submitted for analysis along with the drill core.
