West Timmins Mining Intersects Massive Sulphide Zone at Montana de Oro: Drilling Extends El Rodeo Gold-Silver Zone, Discovers New Zone of Gold Mineralization

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 26, 2007) - West Timmins Mining Inc. (TSX:WTM) announced today that it has intersected a nine metre massive sulphide zone on its 100% owned, 495 square kilometre Montana de Oro Project in the Sierra Madre Belt of Sonora, Mexico. Ongoing drilling has also discovered two new zones of gold mineralization and confirmed the extension of the El Rodeo Gold-Silver Zone. The Montana de Oro Project sits at the heart of the Three State 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 Trogan Deposit and Pan American Silver's Alamo Dorado silver mine.

La Concepcion (LC) Gold System

Drill hole LC07-07 has intersected a nine metre zone of massive sulphide (pyrite (iron)-sphalerite (zinc)-chalcopyrite (copper)) mineralization which cores a 36.60 metre wide silica-sulphide breccia zone within the large La Concepcion (LC) mineralized system. The La Concepcion system is located within the south-central portion of the Montana de Oro project area, approximately 5.45 kilometres southwest of the El Rodeo discovery. Photos of the massive sulphide zone can be viewed on WTM's website at www.westtimminsmining.com. Assay results from the new discovery are pending.

Drill hole LC07-07 was collared to follow up the discovery anomalous gold mineralization in hole LC07-02 collared 40 metres to the south. The upper 25.50 metres of LC07-02 returned an average grade of 0.61 g/t gold, 4.56 g/t silver and 0.03% copper. The uppermost sample in LC07-02 returned 2.50 g/t Au over 1.50 metres. Mineralization in LC07-02 is associated with a zone of moderate silicification and sulphide mineralization (1-5% pyrite, trace chalcopyrite). The silicified breccia zone in hole LC07-07, surrounding the massive sulphide intercept, exhibits both stronger sulphide mineralization and more intense silicification.

Drill hole LC07-03, collared from the same set-up, but at a steeper angle than LC07-02, (-50 vs. -75 degrees, respectively) intersected only weakly anomalous gold values (less than 300 ppb gold) and minor sulphide mineralization. Drill hole LCNE07-01 was drilled to test a copper oxide bearing shear zone, 460 metres to the northeast of holes 02, 03 and 07, and intersected a 35.75 metre interval, from the collar of the hole, which returned weakly anomalous gold, copper and molybdenum values.

El Rodeo Gold-Silver Zone

Two drill holes, collared 250 and 300 metres south of discovery hole ER06-01 (4.80 metre grading 9.58 g/t gold, 122 g/t silver) have confirmed the continuity of the El Rodeo gold-silver zone to the south of the discovery area. Hole ER07-05 intersected 2.56 g/t gold and 157 g/t silver over 0.80 metres and hole ER07-06 intersected 3.52 gold and 86.90 g/t silver over 0.65 metres (see Table 2). Both holes tested the zone at vertical depths of less than 30 metres. Additional drill testing has intersected the mineralized quartz-breccia system over a total strike length of 1,000 metres and it remains open in all directions. In total 18 holes have now been completed in the El Rodeo Zone with 14 of the 18 holes intersecting the mineralized quartz breccia system. The El Rodeo Zone varies in width from 0.40 to 5.80 metres and has only been tested to date to vertical depths of less than 80 metres.

Don Pancho Discovery

Ongoing mapping by WTM has identified a number of historic pits, trenches and small underground workings in the area immediately north of the FR gold zone, approximately 2.50 kilometres southeast of the El Rodeo discovery. Initial drill testing of the Don Pancho vein system has intersected a strongly altered vein system which returned an intercept of 12.75 g/t over 0.70 metres in hole DP07-01 at a vertical depth of less than 45 metres. Drill hole DP07-03, collared 50 metres to the east returned several gold mineralized intervals including an intercept which returned 3.64 g/t gold and 9.40 g/t silver over 1.50 metres (see Table 3).

Holes DP07-02 and DP07-04 were drilled at steeper angles, from the same collar locations as DP07-01 and DP07-03 respectively, and failed to intersect the mineralized zone indicating that the zone dips steeply to the north.

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. Gold values in excess of 3.00 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 also 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. One standard, from hole DP07-02, failed to produce an acceptable value and the related sample batch will be re-analyzed.
