May 12, 2010 Lake Shore Gold Announces Changes to Board of Directors TORONTO, ONTARIO--(Marketwire - May 12, 2010) - Lake Shore Gold Corp. (TSX:LSG) ("Lake Shore Gold" or "the Company") today announced changes to the Company's Board of Directors. Joining the Board is Gianflavio Carozzi, Corporate Treasurer of Hochschild Mining Plc. Departures from the Board include Sethu Raman, Michael Winn, Wayne O'Connor, who did not stand for re-election at the Company's recent annual meeting, and Ignacio Rosado, who has left the Board following his resignation as Chief Financial Officer of Hochschild. Mr. Carozzi joined Hochschild in 2007 and has been Corporate Treasurer since that time. Before joining Hochschild, Mr. Carozzi served as Manager of Global FX and Commodities at General Motors' Treasurer's Office in New York from 2003 to 2007, performed a number of finance-related roles at Nextel Peru between 2000 and 2001 and, prior to that, worked for Telefonica del Peru from 1998 to 2000. Gianflavio holds an MBA and BSc. in Economics. Sethu Raman joined Lake Shore Gold's Board on December 31, 2004 following the acquisition by the Company of all outstanding shares of Holmer Gold Mines Limited through a plan of arrangement. From 1986 to 2004, Dr. Raman was President and CEO of Holmer where he played a leading role in the initial discovery of the Timmins gold deposit and the recognition of the potential of the Timmins West gold trend. Michael Winn joined Lake Shore Gold's Board at the time of the Company's reverse take-over transaction with Aurora Platinum Corp. in 2002 and has made a valuable contribution to developing corporate strategy and helping the Company grow its business. He is President of Terrasearch Inc., a consulting company that provides analysis on mining and energy companies, has worked in the oil and gas industry since 1992, and participates on a number of boards in the mining and oil and gas sectors. Wayne O'Connor joined Lake Shore Gold's Board in November 2009 following completion of the Company's acquisition of West Timmins Mining Inc., where he served as Chairman. Mr. O'Connor was instrumental in assembling the extensive land package on the west side of Timmins that ultimately was held by West Timmins and is currently wholly-owned by Lake Shore Gold, including the Thorne, 144 and Thunder Creek properties. Ignacio Rosado joined Lake Shore Gold's Board in February 2008 following Hochschild's initial investment in the Company. Mr. Rosado played an important role in Hochschild's decision to establish and grow its investment in Lake Shore Gold. Alan Moon, Chairman of Lake Shore Gold, commented: "We are very pleased to welcome Gianflavio to the Board and look forward to working with him as Lake Shore Gold moves forward. We would also like to recognize those leaving the Board. Sethu Raman committed much of his career to establishing and pursuing the potential of the Timmins Mine property and we will forever be grateful for his perseverance and commitment. Michael Winn has been with the Company since its beginning and Lake Shore Gold has benefited greatly from his leadership, advice and counsel. Like Sethu, Wayne O'Connor is a veteran of the Timmins Camp and his work has helped us to establish the very attractive land position we have today. Finally, Ignacio Rosado has been a valued director as we have grown our very productive relationship with Hochschild. These directors have made a significant contribution to the success and growth of Lake Shore Gold. They have served shareholders well and we wish to thank them for all of their efforts."
