OREAS 111b

OREAS 111b is a medium grade Cu ore certified reference material (CRM) prepared from material sourced from the Tritton Copper Project near Nyngan, New South Wales. The deposit consists of sulphide ore bodies (massive pyrite and chalcopyrite breccias) underlying oxide ores. OREAS 111b has a pigeon pair with OREAS 111 which is ~4% lower in Cu grade. OREAS 111b is one of a suite of five CRMs and was prepared from massive pyrite ore material. All five CRMs have been characterised for Ag, As, Cd, Co, Cu, Fe, Pb, Sb and Zn by 4-acid ICP and sodium peroxide fusion ICP methods.
