West Timmins Mining Inc.: Montana de Oro Project Update, Sonora, Mexico

Drilling Resumes at La Dura East El Rodeo Gold-Silver Zone Extended to 850 Metres High-grade Gold-Silver Intersected (35.60 g/t Au, 90 g/t Ag over 1.45 metres) at Don Pancho Gold-Silver Zone Intersected at Fronteriza (including 12.20 g/t Au, 120 g/t Ag over 1.70 metres)

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 25, 2007) - West Timmins Mining Inc. (TSX:WTM) provides the following updates on exploration activities on its 100% owned Montana de Oro Project located in southern Sonora State, Mexico. The Montana de Oro Project covers 557 square kilometres at the heart of the Three Corners Mining District of the Sierra Madre Belt. Exploration to date on the Montana de Oro Project has identified over 20 occurrences of gold-silver and related base metal mineralization which are currently undergoing initial drill testing.

La Dura East Polymetallic Zone

Drilling has now resumed on the northern extension of the La Dura East skarn-breccia trend. The current phase of drilling will initially test high-grade surface discoveries, which returned 1.14 to 10.94% combined lead + zinc (NR07-19, June 26, 2007), located 1,600 metres north of discovery hole LD07-01.

The Company has received and confirmed results from drill holes LD07-03 and LD07-04. Hole LD07-04 collared from the same set-up as LD07-01, but at a steeper angle (70 vs. 55 degrees), intersected 30.55 metres grading 0.82% combined lead and zinc, 2.61 g/t Ag (see cross-section at http://www.westtimminsmining.com/main/?laDura). Drill hole LD07-03 targeted a Cu-Au bearing shear system 1.10 kilometres south of hole LD07-01, outside the main La Dura mineralized trend.

El Rodeo Gold-Silver Zone

Drilling has extended the El Rodeo Zone to 850 metres along strike and to a vertical depth of 65 metres. The El Rodeo Zone remains open along strike to the south and to depth. A high-grade copper-silver intercept (11.30% copper, 429 g/t silver over 0.30 metres) at a vertical depth of approximately 100 metres in hole ER07-16 is distinct from the mineralization intersected to date and may indicate the presence of a previously unrecognized zone of mineralization in the El Rodeo area.

Don Pancho Gold Zone

Shallow testing of the Don Pancho vein system has intersected 1.45 metres grading 35.60 g/t gold and 93.00 g/t silver in hole DP07-06. Hole DP07-06 undercut hole DP07-05 from the same set-up, which returned 0.50 metres grading 0.38 g/t gold and 2.70 g/t silver from the up-dip portion of the same structure. Both intercepts lie above the 50 metre vertical level.

Drill holes DP07-09 and DP07-10 (107 metres west of holes DP07-05 and DP07-06) intersected a zone of fault-associated gold-silver-copper mineralization. Hole DP07-09 intersected 4.13 metres grading 0.28% copper, 1.06 g/t gold and 37.20 g/t silver at the northern contact between diorite and feldspar porphyry. Hole DP07-10B failed to intersect the northern contact but intersected 29.42 metres grading 0.34% copper and 2.91 g/t silver at the southern contact of the porphyry. Hole DP07-10 was lost at a depth of 26.70 metres and hole DP07-10B drilled from the same set up at a steeper angle.

Fronteriza Gold-Silver Zone

Three holes were collared in the north-eastern portion of the Fronteriza gold-silver system, proximal to hole FR06-02 (13.60 metres grading 0.79 g/t gold, 5.19 g/t silver (NR 07-09, March 5, 2007)). FR07-06 drilled 30 metres southwest of hole FR06-02 returned 1.70 metres grading 12.20 g/t gold and 120.00 g/t silver within a 22.85 metre interval grading 1.04 g/t gold and 10.77 g/t silver. Holes FR07-05 and FR07-07, collared 200 metres northeast and 80 metres southwest of hole FR06-02 respectively, both returned only weakly anomalous mineralization. The reported intercepts are interpreted to be 120% of true thickness.

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 by ALS-Chemex. Gold values in excess of 3 g/t were re-analyzed by fire assay with gravimetric finish for greater accuracy. Silver, copper and lead values in excess of 100 ppm, 1% and 1% respectively were repeated 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. Analytical discrepancies were identified by the Company's quality control program but have been resolved to the satisfaction of the Company and the qualified person prior to this release. Mr. Darin Wagner (M.Sc., P.Geo.), the Company's President, has acted as qualified person for this news release. The qualified person has examined the drill core from the majority of the holes reported, reviewed the sampling procedures and the analytical data and the results of the quality control program.
