| Description: OREAS 683 is a platinum group element (PGE) ore certified reference material (CRM) prepared and certified by Ore Research & Exploration Pty Ltd. OREAS 683 has been prepared from PGE ores blended with barren gabbro-norite. The PGE ores were sourced from the Dishaba mine, 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. OREAS 683 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.
