The OREAS range of CRMs are prepared from natural ore and rock samples sourced from deposits throughout Australia, southeast Asia, South America and Africa and cover a spectrum of concentrations and mineralisation styles. Developed exclusively for the mining industry, they are distributed worldwide in over 60 countries. Packaging is predominantly in 10 and 60g single-use units using robust laminated foil pouches or in bulk form in lots of 500g to 25kg. Sulphide-bearing materials are packaged under inert gas or vacuum packed to ensure long term stability.
Sophisticated proprietary technology ensures high levels of homogeneity, with industry-leading repeatability demonstrated for all gold ores down to a 0.5 gram analytical subsample. All CRMs are prepared and certified to ISO standards and are supplied with comprehensive documentation.
