The role of Certified Reference Materials
in mining and exploration projects
OREAS® Certified Reference Materials
As an official distributor of OREAS® Australia, our products cover the entire range of certified reference materials (CRMs) used in mining and exploration projects across West Africa.
What are Certified Reference Materials?
Certified Reference Materials (CRMs) are stipulated by the legal requirements in mining and exploration worldwide. In essence, a CRM represents a known grade composition control sample and is used to test and validate mineral samples extracted in mining and exploration projects during an assay process.
The actual application of CRMs in the industry is divided into two core categories. Geologists use them for grassroots exploration, mine site exploration, resource definition, and grade control. On the other hand, chemists use them to calibrate analytical equipment, validate various analytical methods and QA/QC processes.
What defines quality Certified Reference Materials
for mining and exploration in West Africa
What is the application of Certified Reference Materials
The core application of CRMs in mining and exploration is to estimate and monitor the level of bias in the analysis of various geological samples. In practice, a CRM would be inserted in the sample stream at a frequency of 1 in 20/30 and then used to compare the laboratory test results against the certified values of the inserted CRM.
Put simply; a quality Certified Reference Material could significantly and proactively improve the quality of the assumptions and decisions made at various stages of drilling operations.
