WTM Extends La Dura Copper Zone to Over 1,000 Metres, Montana De Oro Project, Mexico

Intersects Copper-Gold Zone in Hole LC08-39

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 29, 2008) - West Timmins Mining Inc. (TSX:WTM) (the "Company") announced drill results from its 100% owned Montana de Oro Project located in Sonora, Mexico today which extend the La Dura Copper Zone to over 1,000 metres along the current north-south drill section. Copper mineralization has been intersected over down-hole widths of 61 to over 300 metres with grades ranging between 0.10% and 0.22% copper. Observed alteration and mineral zoning patterns continue to indicate that the recent intercepts sit in the outer, or propylitic, shell of a large porphyry copper system which opens under cover to the west, south and southwest.

A 20.35 metre interval of strongly anomalous (0.27 g/t) gold mineralization was also intersected at the top of the Copper Zone in Hole 08-39, the southernmost hole reported. The identification of a gold-enriched portion of the porphyry copper system is a particularly positive development. Drilling on the southern and western extension of the La Dura Copper Zone is currently anticipated to resume during the fourth quarter of 2008, once unusually high water levels in the Baboyahui River recede. Results from nine additional holes in the La Dura Copper Zone area remain pending.

"Drilling has rapidly expanded the scale of the La Dura Copper discovery consistent with the interpretation that we are sitting on the eastern margin of a large porphyry copper system," said Darin Wagner, President and CEO of West Timmins Mining Inc. "The identification of a gold-rich phase in the southern portion of this system adds significantly to the potential of this discovery, as does the identification of similar alteration and anomalous copper, lead, zinc and silver mineralization in drilling 3.5 kilometres to the southwest of the discovery hole."

In addition to the holes reported above two holes drilled over 3.5 kilometres to the south-southwest of discovery hole LC08-29, in the Dura Verde area (DV08-01, -02), have intersected similar host lithologies, strong propylitic alteration and locally anomalous copper and lead-zinc-silver mineralization, consistent with the regional zoning pattern typically associated with large porphyry systems.

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 irregular intervals. 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, examined sum but not all of the drill intercepts reported, reviewed the available technical information for the project, and has verified that there were no discrepancies with respect to the quality control samples submitted for analysis along with the drill core.
