We achieve complete homogenisation even with coarse gold in challenging source materials

When it comes to gold assay accuracy, consistency is everything. That’s why OREAS remains the only Certified Reference Material (CRM) manufacturer to rigorously test and guarantee the homogeneity of gold and platinum group elements (PGEs) across its entire product range.

Using proprietary processing technology, OREAS achieves complete homogenisation, even with coarse gold in challenging source materials. The result is unmatched consistency and reliability in every laboratory sample, providing analysts total confidence in their assay data.

To meet the diverse analytical requirements of mining laboratories worldwide, OREAS® gold CRMs are certified across multiple methodologies, including:

  • Fire Assay
  • Aqua Regia Digestion
  • Cyanide Leach
  • PhotonAssay™
  • Bismuth Fire Assay (Bi FA)

This breadth of certification ensures OREAS® CRMs remain compatible with both established and emerging assay techniques, helping laboratories maintain accuracy, consistency and confidence in every result.
