MONTREAL, QUEBEC (FRANKFURT: EWX) is pleased to announce that has received the final approval of the Toronto Stock Exchange (TSX) to list the common shares of Osisko on the TSX. Osisko will have its common shares commence trading on the TSX on Thursday, November 15, 2007 under the symbol OSK. On commencement of exchange trading, Osisko's shares will be delisted and cease trading on the TSX Venture Exchange.

Sean Roosen, President and CEO of Osisko stated: "The move up to the TSX is an important milestone for Osisko as it progresses towards its goal of becoming a mid-tier gold producer with the development of the Canadian Malartic Project. The TSX is a premier global exchange for the mining industry and the TSX listing of Osisko should provide the company with improved liquidity, improved access to capital and broader market exposure".
