OREAS® Gold CRMs
Our proprietary processing technology is a game changer – we provide quality assurance on the homogeneity of all CRMs produced, regardless of the nature of source materials, including ‘nuggety’ gold ores.
Our procedures do not involve any compositional change to the ore other than grain size reduction.There is no removal of coarse gold particles by sieving or any addition of fine-grained ‘gold minerals’. The OREAS® range is entirely sourced from naturally occurring ore deposits from various mineralisation styles and when appropriate, blended with geologically matching waste rock to achieve target grades.
