Quality Is Everything

When you choose an OREAS® Certified Reference Material, you can trust that our practices, products, and services will meet your specifications and all regulatory requirements. We guarantee the homogeneity and stability of every material, ensuring that any anomalies in QC data are due to laboratory measurement errors, not CRM sampling errors.

The use of CRMs isn’t just QA/QC best practice; they’re mandatory for publicly listed mining companies, improving confidence in ore reserves, drill target selection and company aptitude. Inaccurate or unreliable assay results can lead to misinterpretation of ore grades, financial losses, poor decision-making and damage to a company’s reputation.

OREAS® CRMs are meticulously prepared to be the gold standard, offering unparalleled accuracy and reliability. Every reference material, whether from our OREAS® range or Custom CRMs, is manufactured to the highest world-class standards.

OREAS is the only manufacturer to test and guarantee the homogeneity of gold (and PGE) in all our CRMs, irrespective of the presence of coarse gold in source materials.

Our proprietary processing technology ensures the homogeneity of all materials, overcoming challenges posed by difficult source materials.
