Comments | Location, tonnage and grade of measured + inferred resources of Mount Cannindah + United Allies + Monument zones from Geoscience Australia (2010). Ewers and others (2002) reported 3 Mt at 1.31% Cu, 0.9 g/t Au, containing 39,000 t Cu, 2.7 t Au. Extensive porphyry-related breccia system, shear-controlled veins, skarn at porphyry contact; significant copper concentrations occur where infill of voids in breccia is >30%. Fracturing weak to moderate, locally strong. Middle to upper part exposed. Secondary enrichment weak to moderate, locally strong. Mineralized breccia contains angular clasts and voids filled with hydrothermal sulfides and gangue. |
