Tailored To The Highest Standards

When deposits feature unconventional mineralogy, complex matrices, or require tighter grade matching than off-the-shelf Certified Reference Materials (CRMs) can provide, OREAS Custom CRMs deliver purpose-built standards tailored to the defining attributes of your project.

From complex polymetallic systems and refractory gold to battery metals, rare earths, or narrow grade ranges, OREAS Custom CRMs are engineered to closely replicate your material, ensuring accurate QA/QC across your selected analytical methods.

Material Preparation & Homogeneity

Custom CRMs may be prepared from:

• Client-supplied materials
• OREAS stock materials
• Engineered blends of both

We guarantee the homogeneity of all Custom CRMs produced from client-supplied materials, providing confidence in post-analysis quality control and ongoing performance monitoring.

With more than 500 tonnes of characterised source materials available, OREAS can design blended materials that closely reflect the composition, mineralisation style, and grade distribution of your target orebody.

Production Scale

OREAS Custom CRMs can be produced in batch sizes ranging from 100 kg to 12,000 kg, suitable for exploration, feasibility, production, and long-term site QA/QC programs.

Certification Framework

All Custom CRMs are produced under the same stringent framework applied to our catalogue products.

Certification is undertaken in accordance with ISO guidelines and structured under our ISO 17034-accredited systems, ensuring internationally recognised traceability, statistical robustness, and documentation integrity.

We work with leading analytical laboratories worldwide to ensure access to appropriate analytical methods for your material and commodity type.

Production Timeline

Typical timelines for Custom materials range from 3 to 6 months after receipt of supplied materials, depending on analytical scope, laboratory scheduling, and certification complexity.

Certificate of Analysis

Each Custom CRM is supported by a comprehensive Certificate of Analysis including:

• Certified Values
• Performance Gates (standard deviations)
• 95% Confidence Intervals
• 95% Tolerance Intervals
• Graphical statistical analyses
• Full tabulation of laboratory results

CRMs You Can Rely On

CRMs can be prepared in batch sizes from 100kg to 12,000kg, packed in unit sizes from 5g to 200kg (± inert gas) and certified in a rigorous round robin program for your analytes of interest.

Every reference material, whether from our OREAS range or Custom CRMs, is manufactured to the highest world class standards. Our quality control protocols ensure meticulous attention to detail at every stage, supported by long-standing experts in the field to assist you throughout your entire quality program.

We are the only manufacturer that both test and provide a guarantee* of homogeneity of gold (and PGE) across all OREAS and Custom CRMs irrespective of the presence of coarse gold in the source materials.

*Quality Assurance Guarantee – a coefficient of variation (1RSD) of < 1% when calculated for a typical 30g fire assay using the results from 20 x≤1g INAA results and the Sampling Constant (as per the known relationship between SD and sample mass following Ingamells & Switzer, 1973).
