High-Grade Gold Intersected on West Timmins' Thunder Creek Property, Ontario

(Vancouver, August 1, 2007)��West Timmins Mining Inc. (TSX: WTM)announced today that it has been informed by project operator Lake Shore Gold Corp. (TSX: LSG) ("Lake Shore") that a new zone of high-grade gold mineralization has been intersected on the Thunder Creek property near Timmins, Ontario. The Thunder Creek property and new gold zone are immediately adjacent to Lake Shore's Timmins West property, which hosts 1.3 million ounces of gold in the measured and indicated category and another 200,000 ounces in the inferred category[1]. The character of the mineralization in this new gold zone is similar to the Ultramafic zones that hosts the majority of the gold mineralization at Timmins West.

Hole TC07-30 returned 10.91 g/t gold over 3.65 metres, including 14.68 g/t gold over 2.65 metres from the new UM1 zone. The high-grade intercepts are hosted within a 6.80-metre wide structural zone of strong alteration and mineralization. A second new zone of gold mineralization (UM2) located 8.75 metres further down the hole returned 5.43 g/t gold over 1.20 metres. Both of these mineralized zones are hosted within a large ultramafic body, identical to the host of the Ultramafic zones on the Timmins West property. These two zones appear to be sub-parallel to the Rusk Zone which returned 27.60 g/t gold over 0.50 metres from a visible gold bearing intercept lower in the same hole. The Rusk Zone is located within another intensely altered shear zone along the southeast contact between the ultramafic body and adjacent sedimentary lithologies.

Lake Shore President and CEO Brian Booth noted the new mineralized zones at Thunder Creek are shallow, at 280 metres below surface, and remains open along strike and at depth. "For the first time at Thunder Creek we have hit ultramafic-style gold mineralization that is similar to the Ultramafic zones at Timmins West," said Booth. "This intersection confirms the potential of the Thunder Creek ultramafic intrusion to host high-grade gold mineralization with significant upside potential. The new intersections are located only 865 metres southwest of the location of the planned Timmins West shaft. If the discovery proves to be of sufficient size it may be accessible from the Timmins West shaft." He added that one rig will continue to drill at Thunder Creek to determine the geometry of the new zones prior to making the decision to add additional drills.�

"The discovery of high-grade gold zones within the ultramafic sequence at Thunder Creek continues to demonstrate the potential of the West Timmins District," said Darin Wagner, President and CEO of West Timmins Mining. "The ultramafic body which hosts the new discovery can be traced for over 8,000 metres through our 114 square kilometre West Timmins Gold Project. This sequence is clearly a priority target for ongoing drill testing on our 100% owned and joint venture properties."

Lake Shore Gold may earn a 60% interest in Thunder Creek Property pursuant to an option agreement with West Timmins Mining Inc. through a series of cash and share payments and by completing $1.7 million in exploration expenditures on the property over a five-year period ending in September 2008. Approximately $1 million in expenditures have been incurred to date.

Quality Control

The following information is supplied by the project operator with respect to the information contained herein. Lake Shore Gold has implemented a quality-control program to ensure best practice in the sampling and analysis of the drill core.�Assays have been completed using a standard fire assay with a 50g aliquot. For samples that return a value greater than 3 grams per tonne gold, another pulp is taken and fire assayed with a gravimetric finish. Zones with visible gold were conducted by pulp metallic analysis. NQ size drill core is saw cut and half the drill core is sampled in standard intervals. The remaining half of the core is stored in a secure location. The drill core is transported in security-sealed bags for preparation at ALS Chemex Prep Lab located in Timmins, Ontario, and the pulps shipped to ALS Chemex Assay Laboratory in Vancouver, B.C. ALS Chemex is an ISO 9001-2000 registered laboratory preparing for ISO 17025 certification.

Lake Shore's Qualified Person ("QP") for the Thunder Creek property is Mr. Jacques Samson, P.Geo. As QP he has prepared or supervised the preparation of the scientific or technical information for the property.
