WTM Intercepts Additional High-Grade Zinc-Copper Mineralization at La Dura West

- 11.14% Zinc, 0.64% Copper, 24.26 g/t Silver and 0.37 g/t Gold over 4.93 Metres and - 6.00% Zinc, 0.31% Copper, 17.82 g/t Silver and 0.23 g/t Gold over 7.54 Metres

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 9, 2007) - West Timmins Mining Inc. (TSX:WTM) announced today that drill hole LC07-09, collared 75 metres west of previously announced hole LC07-07, has cut two intervals of zinc-copper-silver-gold mineralization in the La Dura West area of the Company's 100% owned Montana de Oro Project in Sonora, Mexico.

The lower intercept in hole LC07-09 returned 11.14% zinc, 0.64% copper, 24.26 g/t silver and 0.37 g/t gold over 4.93 metres (16.17 feet) and the upper intercept returned 6.00% zinc, 0.31% copper, 17.82 g/t silver and 0.23 g/t gold over 7.54 metres (24.73 feet). The two sulphide-rich intervals are separated by a quartz diorite dyke which hosts a gold-enriched zone grading 0.87 g/t gold and 8.51 g/t silver over 10.35 metres (33.95 feet) (see cross-section at www.westtimminsmining.com).

"The polymetallic mineralization at La Dura West continues to demonstrate good grade and thickness," said Darin Wagner, President and CEO of West Timmins Mining. "The quartz diorite dyke in hole LC-09 bisects two zones of higher grade polymetallic mineralization within a 34.48 metre wide mineralized interval. The lower intercept in hole LC-09 returned the highest zinc grades encountered to date within the large La Dura system."

Drill hole LC07-08, drilled from the same collar location as LC07-07, but rotated 30 degrees to the west, intercepted a 16.75 metre (54.94 foot) wide mineralized zinc-copper-silver-gold stockwork (See Table 1) before terminating in the same quartz diorite dyke intersected in hole 09. The stockwork zone in hole -08 is similar to that observed in the hanging wall of the main zone in hole 07. Drilling is expected to resume in the La Dura East and West areas within the next several days.

Drill hole LC07-06, collared prior to the La Dura West discovery and drilled 160 metres to the south of the mineralized zone intersected a multi-phase diorite intrusion hosting weakly anomalous copper and gold mineralization.

The La Dura East and West discoveries are located in the south-central portion of West Timmins 100% owned, 557 square kilometre Montana de Oro Project in the Sierra Madre Belt of Sonora, Mexico. The Montana de Oro Project sits at the heart of the Three States District, less than 50 kilometres from seven 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 verified that there were no discrepancies with the respect to the quality control samples submitted for analysis along with the drill core.
