| Comments | Location, tonnage and grade of inferred resource from Geoscience Australia (2010). Porphyry Cu-Au mineralization related to porphyritic monzodioritic stocks, plugs and dikes. Deposit is covered by 50 m of alluvium; drill intercepts: 206 m at 0.37% Cu and 0.51 g/t Au; 50 m at 0.5% Cu and 0.8 g/t Au. Locally overprinted by albite-sericite-pyrite assemblage associated with Devonian orogenic gold veins. |
