TORONTO, ONTARIO--(Marketwire - Aug. 27, 2009) - Lake Shore Gold Corp. (TSX:LSG - News; "Lake Shore Gold" or the "Company") and West Timmins Mining Inc. (TSX:WTM - News; "West Timmins") today announced that they have signed a definitive business combination agreement under which Lake Shore Gold has agreed to acquire all of the outstanding common shares of West Timmins. The business combination will create the new large-scale, wholly-owned Timmins West Gold Mine Complex on the western Timmins mining trend, an extension of the world-class Timmins mining trend where approximately 70 million ounces of gold have been produced over the last century. The Timmins West Gold Mine Complex will consist of the Company's adjacent 100%-owned Timmins Mine, with existing mine infrastructure, the Thunder Creek Joint Venture ("Thunder Creek"), where high-grade intercepts have been reported within 800 metres of the Timmins shaft, and an extensive land package of adjacent exploration properties, giving Lake Shore Gold a dominant position in this highly prospective area.

Under terms of the agreement announced today:

- West Timmins shareholders will receive 0.73 of a Lake Shore Gold share per West Timmins share

- Pro forma the transaction, Lake Shore Gold will be owned 67% by current Lake Shore Gold shareholders and 33% by current West Timmins shareholders

- The transaction values West Timmins at approximately C$319 million based on current shares outstanding

- Three of 13 seats of the Lake Shore Gold Board will go to West Timmins

- Transaction was unanimously approved by the Boards of both companies, with the commitment of votes representing 5.3% of West Timmins common shares having been secured

- Transaction to be completed by way of a court-approved plan of arrangement

Tony Makuch, President and CEO of Lake Shore Gold, commented: "This is an exciting time for the shareholders of both Lake Shore Gold and West Timmins as we take a very important step towards building Canada's next mid-tier gold producer. Through this combination we are creating a dominant land position which covers about 130 square kilometers along the Timmins gold structure west of the Mattagami River Fault, where the geologic setting is very similar to the geology of past producing mines in Timmins. The discoveries at Timmins Mine and Thunder Creek confirm the exploration potential of this large land package and suggest that the potential for additional discoveries is excellent. We are also consolidating Thunder Creek and the Timmins Mine into one property, creating a wholly-owned mining complex with the potential for large-scale, long-life operations, well beyond what was originally envisioned at the Timmins Mine. We can also potentially expedite production from Thunder Creek by at least three years, and realize significant synergies, through the use of the Timmins Mine infrastructure, permits, closure plans, management and workforce. We may also realize the reserve and resource scale to justify a dedicated mill, providing the potential for further synergies."

Lake Shore Gold and West Timmins currently own 60% and 40% of Thunder Creek, respectively, with Lake Shore Gold's other Timmins assets comprised of projects nearing production, including the 100%-owned Timmins Mine and Bell Creek Complex (Bell Creek Mill and Mine and Vogel and Schumacher Properties). Lake Shore Gold is the operator of Thunder Creek. In addition to its 40% interest in Thunder Creek, West Timmins has approximately 120 square kilometres of prospective wholly-owned exploration property in close proximity to Thunder Creek. Among these properties are the Thorne Property, with a near 450,000 ounce inferred resource and recent encouraging drill results including 11.15 gpt over 7.30 metres on July 6, 2009, and the 144 Property, with 4.0 kilometres of the same volcanic/ultramafic, intrusive/sedimentary contact which hosts the Timmins and Thunder Creek deposits. In Mexico, West Timmins owns 100% of the high-grade Lluvia de Oro gold-silver and Montana de Oro projects.

Darin Wagner, President of West Timmins said: "This merger allows our shareholders to rapidly transition from an exploration to a near-term production scenario and still participate in the exploration upside of the combined assets of the two companies moving forward. The marriage of Thunder Creek with the Timmins Mine infrastructure, the Bell Creek Complex and the exploration potential of our assets in Timmins are all a natural fit. Through this transaction we reduce our effective interest in the Thunder Creek joint venture from 40% to 33%, in the combined company, and in doing so we add a significant interest in the Timmins Mine, the Bell Creek Complex and additional exploration potential. This business combination will allow for a rapid pace of development at Thunder Creek which provides an excellent opportunity to significantly increase the resource base and future production profile of the new company. The Board of Directors of West Timmins recommends that shareholders vote in favour of the transaction and the creation of a new aggressive, growth focused gold company."

Mr. Makuch added: "Once the transaction has been completed, we plan to commence an aggressive underground advanced exploration program at Thunder Creek, accessing mineralization at the 240 metre level (where results have included 24.61gpt over 7.0 metres) from the Timmins Mine ramp and deeper mineralization at the 650 metre level (where results have included 12.75gpt over 83.4 metres) from the Timmins Mine shaft. Based on our current schedule, we expect to be into the Thunder Creek mineralization by the fourth quarter of 2010 and to be bulk sampling before the end of the year. The Timmins Mine shaft has been designed to support a much larger operation than originally envisioned in the pre-feasibility study. We are also considering deepening the shaft from 710 metres to 1,200 metres. Furthermore, over the next year we will be deciding whether to undertake an expansion of our wholly-owned Bell Creek Mill from 1,500 tonnes per day currently to 3,000 tonnes per day, or to construct a new, stand-alone mill west of Timmins to process ore from our Timmins West Gold Mine Complex. We have made excellent progress with our growth plans to date, and by completing this transaction have taken another important step towards becoming Canada's next mid-tier gold producer."
