OREAS 501e was prepared from a blend of porphyry copper-gold ores, barren granodiorite and a minor quantity of Cu-Mo concentrate. The ores were sourced from the Cadia-Ridgeway Mines and Northparkes Mine. Both mining operations are located in the Central West of New South Wales, Australia. The barren granodiorite was sourced from the mafic, S-Type, Late Devonian Bulla Granodiorite complex located in northern Melbourne, Australia. Twenty-seven commercial analytical laboratories participated in the program to certify the following:
Gold by instrumental neutron activation analysis (INAA) on 20 x 85mg
subsamples was also undertaken at ANSTO, Australia to confirm
homogeneity.
