8,000 Metre Drill Program Begins on West Timmins' Thunder Creek Gold Property

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 4, 2007) - West Timmins Mining Inc. (the "Company") (TSX:WTM) announced today that drilling has begun testing the Rusk Gold Occurrence on the Thunder Creek Gold Property, located approximately 1,000 metres south of Lake Shore Gold's 1.29 million ounce (indicated) Timmins West gold deposit.

Lake Shore Gold Corp., operator of the Thunder Creek Property, has informed the Company that it plans to complete a minimum of 8,000 metres of drilling to further test two zones of gold mineralization intersected by previous drilling and trenching.

"The target zones on the Thunder Creek Property share a number of geological and geophysical similarities with Lake Shore Gold's deposit located immediately to the north," said Darin Wagner, President of West Timmins Mining. "Lake Shore Gold has planned a very aggressive drill program to follow-up the positive results from the surface trenching completed in late 2006 on the Thunder Creek Property as they prepare to begin shaft construction and underground exploration on their adjacent Timmins West gold deposit."

The principal target of the Thunder Creek drill program will be the Rusk Gold Occurrence, which lies on the same volcanic-sedimentary contact which hosts the Timmins West deposit. Surface sampling by Lake Shore Gold has returned values ranging from below detection to 71.90 g/t gold, while drill testing in 2004 intersected a 25 metre wide zone of gold mineralization including 2.05 metres grading 5.84 g/t gold.

The Thunder Creek Property is 100% owned by West Timmins Mining. Lake Shore Gold has an option to earn a 60% interest in the Thunder Creek Property by making cash and share payments of C$370,000 and 100,000 common shares of Lake Shore Gold in favour of WTM, and by completing C$1,705,000 in exploration expenditures on the Property over a five year period. The Thunder Creek Property agreement is current in its third year.

Quality Control and Assurance

Geochemical results reported were supplied to the Company by Lake Shore Gold Corp. Drilling results were previously reported (see Lake Shore Gold Corp. news release dated Feb. 14, 2005). Channel sample results for the Rusk discovery were from saw-cut, continuous channel samples collected by Lake Shore from the stripped and washed trenches.

Individual channel samples were sealed on site and transported to the preparation facilities of Swastika Laboratories in Swastika, Ontario under the care and control of the staff of Lake Shore Gold Corp. Samples were assayed for gold by standard fire assay-ICP finish with a 30 gram charge. Mr. Jacques Samson (P.
