WTM Identifies High Grade Copper-Silver Vein System at La Bufa

Sample Returns 7.20% Copper, 1,470 g/t Silver

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 17, 2007) - West Timmins Mining Inc. (TSX:WTM) announced today that it has identified a high-grade copper-silver vein system on its La Bufa Project in Chihuahua, Mexico. A grab sample of vein material, exposed over a width of 3.00 metres, collected during a regional stream sediment program, returned 7.20% copper, 1,470 g/t silver and 0.05 g/t gold. West Timmins has staked an additional 40 square kilometres in the La Bufa area to cover the strike projection of this new vein system and a parallel system identified one kilometre to the east which returned 0.49% copper, 4.80 g/t silver and 2.24 g/t gold. Several multi-element (copper-gold-silver) stream sediment anomalies have also been identified within the project area.

The new discoveries are located 3.00 kilometres east of the former producing Carmen copper-gold-silver deposit owned by WTM. The Carmen (La Bufa) Mine produced approximately 1,000,000 tonnes at an average grade of 2.50% copper, 2.80 g/t silver and 2.90 g/t gold between 1947 and 1958. The steeply dipping Carmen vein system was traced for over 800 metres along strike and mined from 16 levels over widths of 2.0 to 6.0 metres. Recent sampling by the Company has confirmed the presence of anomalous gold mineralization (0.40 to 18.70 g/t gold) hosted in low sulphide, silicified zones in the hanging wall to the main structure at Carmen. West Timmins wholly owned Mexican subsidiary, Minera Golondrina S.de R.L. de C.V., purchased a 100% interest in the Carmen Mine and surrounding exploration property in 2006.

A systematic sampling program of the Carmen Mine area and follow-up sampling of the new discoveries are anticipated to commence within the next six weeks.

WTM's La Bufa Project is located in The Three States Mineral District of south-western Chihuahua State, Mexico which also hosts the Company's Montana de Oro and Lluvia de Oro projects. The La Bufa Project is road accessible and is located 25 kilometres east of Goldcorp's El Sauzal Gold Mine and 75 kilometres east of WTM's Montana de Oro Project.

Quality Control and Assurance

Geochemical results reported herein are from grab samples collected from surface on the Company's La Bufa Project. Sampling was conducted on site by trained personnel and sealed samples were transported to ALS-Chemex's preparation facilities in Chihuahua, Mexico by employees of consulting firm Minera Cascabel S.A. de C. V. on behalf of West Timmins Mining Inc.

All samples were assayed for gold by standard fire assay- ICP finish with a 50 gram charge. Samples additionally underwent 34 element ICP-MS analysis. Gold values in excess of 3.00 g/t were re-analyzed by fire assay with gravimetric finish for greater accuracy. Silver and copper values in excess of 100 ppm and 1% respectively were also repeated by fire assay. For quality control purposes blank and analytical control standards were inserted into the sample sequence at regular intervals - no discrepancies are reported. Mr. Darin Wagner (M.Sc., P.Geo.), the Company's President, has acted as non-independent qualified person for this news release. The qualified person has visited the project site and independently verified some, but not all, of the analytical results reported.
