As at 30 June 2010, the Copernicus Project Mineral Resource (100%) stood at 812,000 tonnes at 1.23% nickel, 0.82% copper and 0.04% cobalt for 10,000 tonnes contained nickel, 6,700 tonnes contained copper and 360 tonnes contained cobalt. The Mineral Resource is largely classified as Measured and Indicated due to the good continuity of the main mineralised zone, the adequate drill hole spacing, and the confidence gained from data validation. Small zones of isolated mineralisation have been classified as Inferred due to uncertainties in continuity of grade and extent. Within the confines of the open pit, the resource is classified as Measured due to the greater density of drilling, and forms the basis of the Project Mining Ore Reserve.
The Copernicus Mineral Resource (Measured category) has been converted into a Proven (open pit) Ore Reserve (100%) of 365,000 tonnes at 1.03% nickel, 0.63% copper and 0.04% cobalt for 3,800 tonnes contained nickel, 2,300 tonnes contained copper and 100 tonnes contained cobalt.
