OREAS 13b was prepared from ores of platinum group elements (PGEs), copper, nickel and gold dispersed in a gabbro matrix.
The Gabbronorite was obtained from a mafic to ultramafic intrusion complex (Giles Complex) within Mesoproterozoic granulites of the Musgrave Province, about 120km west of Warburton, WA (Australia).
The nickel concentrate was sourced from Xstrata’s Cosmos mine (Western Australia), the copper concentrate from Glencore’s CSA Mine (New South Wales, Australia), the PGE ore from one of Anglo Platinum’s Merensky Reef mines (South Africa) and the gold ore from Newcrest’s Lihir mine (Papa New Guinea).
