OREAS 160 is a copper blank certified reference material (CRM) prepared and certified by Ore Research & Exploration Pty Ltd. The material was sourced from Xstrata's Mt Isa copper deposits located near the township of Mt Isa in north-west Queensland. The deposits are hosted by brecciated siliceous and dolomitic rock masses within the Urquhart Shale comprising complex and dissociated veins with chalcopyrite, pyrite and pyrrhotite with grades of 3-4% copper. OREAS 160 is sourced from barren copper material and is one of a suite of seven CRMs characterised for Cu, Fe, S, CaO, MgO, Al2O3, SiO2, Ag, Pb, Zn and Co by both sodium peroxide fusion ICP and 4-acid ICP methods.
