| Description: OREAS 684 is a platinum group element (PGE) ore certified reference material (CRM) prepared and certified by Ore Research & Exploration Pty Ltd. OREAS 684 has been prepared from PGE ores sourced from Merensky Reef ores from the Bushveld Complex, from sites owned and operated by Anglo American Platinum, South Africa. The common minerals of economic importance within a pegmatitic pyroxenite host are sulphides of iron, nickel, copper and alloys of the PGE's. OREAS 684 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.
