OREAS 149
OREAS 149 is a certified reference material (CRM) prepared from spodumene-rich pegmatite ore blended with granodiorite and with minor additions of Sn oxide ore and Nb concentrate. The pegmatite was sourced from the Greenbushes Mine located just south of the town of Greenbushes in the south-western corner of Western Australia. Sn lateritic ore material was sourced from the Doradilla Project located in north central NSW and the Nb concentrate was sourced from Anglo American Brasil Catalão’s niobium mine in Goiás, Brazil.
OREAS 149 is one of three CRMs ranging 0.49 – 2.2% L2O and contains 113 certified values (and 60 indicative values) including majors and traces by fusion XRF, fusion ICP and 4-acid digestion.
