Trusted Since 1988

OREAS supports the global mining industry with high-quality geochemical Certified Reference Materials (CRMs) designed to improve analytical accuracy and confidence in assay results. As exploration increasingly targets more complex and remote mineral systems, the need for reliable geochemical data continues to grow.

With deep expertise in geochemistry and certification, OREAS produces reference materials that support laboratories and mining professionals in monitoring analytical performance and maintaining robust QA/QC programs. Our CRMs, produced under our ISO 17034 accreditation, are used across the resource development lifecycle from early-stage exploration through to production and resource evaluation.

Unlike synthetic standards, OREAS materials are derived from real ore source materials, ensuring they closely reflect the geological complexity encountered throughout the mining industry.

Based in Melbourne, Australia, and part of the AnalytiChem Group, OREAS combines large-scale manufacturing capability with global distribution. As the world’s largest stockists of ready-made geochemical reference materials, with more than 500 tonnes of CRM inventory available, OREAS supports rapid supply to laboratories and mining operations worldwide. Our offering spans widely used OREAS catalogue CRMs and matrix-matched Custom CRMs, each developed to reflect the geological complexity of specific ore bodies and mining environments.
