The Exchange issued its conditional approval of the Business Combination on April 21, 2011. Silver Ridge has obtained the written consent of the majority of its shareholders to the Business Combination in accordance with the rules of the TSX Venture Exchange (the "TSX-V"). Pursuant to the Master Agreement, Silver Ridge's wholly owned subsidiary, 7595158 Canada Ltd. has amalgamated with NMC. Silver Ridge has issued 55,633,873 common shares in exchange for the 59,633,873 issued and outstanding shares of NMC, which have been cancelled. The amalgamated company (called NMC Mining Corp.) has become a wholly-owned subsidiary of Silver Ridge. In connection with the completion of the Business Combination, Silver Ridge has changed its name to PNG Gold Corporation. The Business Combination is subject to final acceptance from the TSX-V. PNG will issue a news release once the TSX-V has issued its final Exchange Bulletin.

Through NMC, PNG holds a 50% interest in the Normanby and Sehulea Properties in Papua New Guinea, and an option to acquire the remaining 50%. NMC's Normanby Property is the focus of exploration efforts.
