OREAS 680

OREAS 680 is a copper-nickel-platinum group element (PGE) ore certified reference material (CRM) prepared and certified by Ore Research & Exploration Pty Ltd. OREAS 680 has been prepared from PGE-rich ore blended with barren gabbro-norite and high grade copper and nickel ores. The PGE ore was sourced from the Dishaba mine site owned and operated by Anglo American Platinum Ltd. The Dishaba mine is located in the west of Limpopo province, South Africa, approximately 250 kilometres north of Johannesburg. The common minerals of economic importance within a pegmatitic pyroxenite host are sulphides of iron, nickel, copper and alloys of the PGE’s. The barren gabbro-norite was sourced from the Late Cambrian Black Hill Norite Complex located 85km east of Adelaide, Australia. The high grade nickel ores were sourced from the komatiite-hosted Prospero & Tapinos deposits within the Agnew-Wiluna portion of the Norseman-Wiluna greenstone belt, Western Australia. The high grade copper ore was sourced from the Sepon copper deposit located in south-central Laos. OREAS 680 is one of a suite of five PGE ore CRMs ranging in 4E concentrations (4E = 4 elements; platinum (Pt), palladium (Pd), rhodium (Rh) and gold (Au)) from 0.82 to 6.1ppm.
