OREAS 62f was prepared from coarse reject splits of gold-silver ore samples blended with barren andesite. The gold-silver ore was sourced from the Cracow mine located 500km northwest of Brisbane in Queensland, Australia. The barren andesite was sourced from the Carboniferous Blair Duguid Hypersthene Andesite intrusive, located 70kms northwest of Newcastle, Australia. Cracow is a low sulphidation epithermal deposit hosted by meta-andesitic volcanics. High grade gold mineralisation occurs within fissure quartz veins and is associated with zones of silicification, present as quartz lode breccia and as quartz vein breccia. OREAS 62f is one of a suite of three CRMs ranging in gold content from 2.47 to 9.71ppm.
