OREAS 620 was prepared from Zn and Cu VHMS ores sourced from the Gossan Hill deposit at Golden Grove located 338km NNE of Perth in the Murchison Province of the Archaen Yilgarn Craton, Western Australia. The VHMS deposits are hosted within and underlain by a layered rhyodacitic volcanoclastic succession. The Gossan Hill ores have been blended with fresh, barren rhyodacite material sourced from a quarry approximately 30km east of Melbourne, Australia to achieve the desired grades. The main mineralisation assemblage consists of sphalerite, chalcopyrite and lesser galena with a gangue of pyrite, pyrrhotite and magnetite. Smith et al. (as cited in Smith, 2003) noted the ore shoots contain many chalcophile, or partly chalchophile elements namely Fe, S, Cu, Pb, Zn, Co, As, Sb, Bi, Cd, In, Mo, Ag, Sn, Ge, Se, Te, Hg and Au. OREAS 620 is one of a suite of five CRMs ranging in grades from 0.18-3.10% Cu, 1.0-10.2% Zn, 0.25-2.21% Pb, 22-103ppm Ag and 0.68-1.85ppm Au.
