VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 29, 2007) - West Timmins Mining Inc. (TSX:WTM - News) announced today that initial drill testing of the La Dura (LD) base metal zone on the Montana de Oro Project has returned 95.75 metres (estimated 85 metres true thickness) grading 2.51% combined lead + zinc, 8.81 g/t silver and 0.08 g/t gold from hole LD07-01. The intercept includes two higher grade sections which returned 4.70 metres grading 0.63 g/t gold, 12.76 g/t silver, 8.75% combined lead + zinc and 8.95 metres grading 0.05 g/t gold, 27.59 g/t silver and 7.22% combined lead + zinc.

Hole LD07-01 is located 1.45 kilometres east of the disseminated and massive sulphide intercept (Hole LC07-07) announced April 26, 2007 for which assay results remain pending. The LD Zone is part of the same large, intrusive-related base-precious metal bearing system. Additional lead-zinc skarn occurrences are known in the La Dura area for over five hundred metres to the north, 900 metres to the south and 600 metres to the west of hole LD07-01, including surface occurrences of greater than 10% combined lead + zinc. Drilling in this area is continuing.

"The scale of the sulphide intercepts and surface mineral occurrences discovered to date in the La Dura area indicates the presence of a large base and precious metal bearing intrusive-related (porphyry-skarn) system that we are beginning to test," said Darin Wagner, President of West Timmins Mining.

The LD Zone is located in the south-central portion of West Timmins' 100% owned, 495 square kilometre Montana de Oro Project in the Sierra Madre Belt of Sonora, Mexico. The LD Zone is one of several mineralized zones currently being drill tested within the Project. 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 El Sauzal gold deposit, Palmarejo Silver and Gold's Palmarejo-Trogan deposit and Pan American Silver's Alamo Dorado silver mine.

Hole LD07-01 collared into skarn-hosted lead-zinc mineralization and terminated in a strongly altered quartz diorite intrusion. Two additional holes (LD07-02 and 03) have been completed to test zones of copper-gold skarn mineralization within the same system 1,300 and 1,100 metres south and southwest of LD07-01 respectively. Several unsourced precious and base metal stream sediment anomalies, including a 2.50 g/t gold in stream sediment anomaly, are present along the northern extension of the LD trend.

Also reported were the results of drill holes LC07-04 and LC07-05 which were drilled in the hanging wall of the La Concepcion (LC) Zone, 250 metres west-northwest of the massive sulphide intercept in hole LC07-07. Both holes intersected broad zones of silica alteration and weakly disseminated pyrite-chalcopyrite mineralization but only weakly anomalous precious and base metal values. Recently received airborne magnetic data indicates these two holes were drilled near the western margin of the intrusive-related system. For more information visit www.westtimminsmining.com.

Two drills continue to turn on the Montana de Oro project testing the La Dura system and the El Rodeo gold-silver zone 4.5 kilometres to the northeast. Drilling also continues on the Company's Yoquivo Gold-Silver Project located within the Sierra Madre Gold Belt.

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.
