3 Sunridge Gold – Highlights Feasibility underway at Debarwa. Option to mine and direct ship 18-20% copper material being studied. Estimated capital cost of “DSO” mine ~$15 million Prefeasibility Study on Northern Deposits (Emba Derho, Adi Nefas, Gupo, and overlap on Debarwa) deposits early in 2011 Definition drilling begun at Debarwa. Expansion drilling to start at Emba Derho and Adi Nefas in January 2011 Expansion drilling scheduled for late 2010/early 2011 at Adi Nefas and Debarwa “De-riskification” of region continues – Bisha Mine on track for com- missioning late 2010 Discovery of potential new VMS district in Madagascar – drilling to begin in spring 2011 Well funded to complete all studies and exploration work over next couple of years – over $28 million in treasury
