Tailored To The Highest Standards
When deposits or materials feature challenging matrices, specific grade ranges, or analytical requirements not adequately covered by catalogue products, OREAS® Custom Certified Reference Materials (CRMs) provide solutions tailored to the technical requirements of your project.
From refractory gold and polymetallic systems to battery metals, rare earths, and tightly constrained grade ranges, OREAS Custom CRMs support reliable QA/QC monitoring and greater confidence in analytical performance across your selected methods.
Material Preparation & Homogeneity
Custom CRMs can be produced from:
- Client-supplied materials
- OREAS source materials
- Custom blends of both
With more than 500 tonnes of characterised source materials warehoused onsite, OREAS can develop CRM blends that closely reflect the composition, mineralisation style, and grade profile of your target orebody.
Production Scale
Available in batch sizes from 50 kg to 12,000 kg, supporting the full project lifecycle from early-stage exploration and feasibility studies through to mine production, downstream metallurgical processing, and long-term operational QA/QC.
Certification Framework
All OREAS Custom CRMs are produced under the same rigorous framework applied to OREAS catalogue products.
Certification is conducted in accordance with internationally recognised guidelines and under OREAS’ ISO 17034 accredited systems, providing confidence in traceability, statistical validity, documentation integrity and auditability.
OREAS works with leading analytical laboratories worldwide to ensure appropriate analytical methods are selected for your commodity and matrix. We select laboratories based on technical capability, accreditation, and suitability for the specific analytical requirements of the project.
Certificate of Analysis
Each Custom CRM is supplied with a comprehensive Certificate of Analysis including:
- Certified values and their 95% expanded uncertainties
- 95% tolerance intervals (a measure of homogeneity)
- Performance gates (based on standard deviations)
- Graphical round robin data for key analytes
- Tabulated full laboratory results
Development Timeline
Typical development timelines range from 3–6 months following receipt of source materials, depending on analytical scope, laboratory scheduling, and certification complexity.
