Reference information

Comments Intercept at 0.28% average Cu-equivalent grade. Location from Geoscience Australia (2010); estimated Cu-equivalent grade from Ford and others (1976). Fracture-bound and disseminated ore minerals. Ore area 3.0 square km, alteration A axis 5.9 km alteration B axis 2.5 km, Alteration area 2.6 square km, sulfide A axis 4.1 km, sulfide B axis 2.0 km. Explored 1961-1969; less than or equal to0.5%Cu equivalent (includes Mo); apparently low-grade. Fracturing weak to moderate, locally strong. Middle to upper part exposed. Secondary enrichment weak to moderate, locally strong.
