OREAS 47 is an augmented Canadian glacial basal till sourced from outside of Chibougamau, Quebec. The till composition reflects the geochemistry of the surrounding Archean greenstone belts and felsic intrusives with minor additions of various ores (PGE + REE + Li) and concentrates (base metals) to achieve anomalous concentration levels. Cobbles were removed prior to processing and all material has undergone sterilisation. A pure glacial till is also available (see OREAS 46).
