OREAS 507b was prepared from a blend of porphyry copper-gold ore, barren granodiorite and a minor quantity of Cu-Mo concentrate. The ore was sourced from the Northparkes Mine 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:
20 x 85mg subsamples was also undertaken at ANSTO, Australia to confirm homogeneity.
