Highest Performance. Trusted Worldwide.
When accuracy matters, OREAS Gold Certified Reference Materials (CRMs) set the standard. With over 35 years of experience, we create Certified Reference Materials to closely match your field samples, ensuring commutability across fire assay, fusion, ICP-MS, ICP-OES, PhotonAssay and other analytical methods.
Our portfolio includes 130+ CRMs spanning all major gold deposit types and grade ranges, from orogenic and epithermal (high/low sulphidation) to porphyry, IOCG, Carlin, Witwatersrand, VMS, and magmatic systems. This breadth ensures your QA/QC program is always supported by fit-for-purpose standards, regardless of deposit or matrix complexity.
Every OREAS Gold CRM undergoes rigorous homogeneity testing using INAA at ANSTO (Australia) or Actlabs (Canada). This non-destructive, highly precise method quantifies within- and between-unit consistency, even on subsamples as small as 85 mg — giving labs confidence that each unit delivers reliable, reproducible results. For further information, see our technical note.
To streamline monitoring, each CRM comes with a Certificate of Analysis and DataPack, providing complete transparency of preparation, characterisation, and uncertainty. Backed by ISO 17034 accreditation and trusted by labs worldwide, OREAS Gold CRMs give you the assurance that your QA/QC data is accurate, robust, and globally recognised.
