OREAS 80 is a nickel sulphide Certified Reference Material prepared from a suite of natural ores and geological materials sourced from several world-class mining and exploration operations. The blend incorporates low- and high-grade nickel sulphide ores from Leinster region (Western Australia), supplemented by ultramafic hosted PGE ores from the UG2 Reef (South Africa), and gabbro-norite material from Black Hill (South Australia).
OREAS 80 has been characterized using the following methods:
Certified values for applicable analytes are operationally defined for each method, with results under OREAS ISO 17034 scope of accreditation.
