OREAS Geological Standards

Industry-Leading Certified Reference Materials

For over 35 years, the OREAS brand has been a global leader in Certified Reference Materials (CRMs) for the mining, exploration, and analytical sectors. Renowned for industry-leading homogeneity, particularly in course gold containing products, OREAS CRMs are meticulously tested to deliver unmatched accuracy and reliability. Each CRM undergoes a rigorous preparation process, including extensive inter-laboratory testing to meet internationally recognized standards set by the International Organization for Standardization (ISO). With a comprehensive portfolio covering a wide range of commodities and mineralization styles, OREAS CRMs play a vital role across multiple functions of the mining lifecycle.

Natural Ore CRMs for Maximum Data Integrity

OREAS CRMs are manufactured from natural ores sourced from mining deposits across Australia, Southeast Asia, North and South America, and Africa. These materials include various types of metals, such as refractory gold and other metals hosted in complex mineral structures. By relying on natural ore sources, OREAS CRMs exhibit consistent behavior during laboratory sample preparation, which is crucial in maintaining the integrity of analysis and delivering results that are accurately comparable to field data. When matrix-matched materials are preferred, we provide a comprehensive Custom CRM service under the OREAS brand using customer-supplied materials, backed by a guarantee of quality and homogeneity. In the mining industry, the importance of using CRMs cannot be overstated, particularly for publicly listed mining companies. The utilization of CRMs is mandated for ensuring compliance with regulatory standards and enhancing confidence in ore reserve estimates and drilling target selections. Inaccurate assay results can lead to significant financial repercussions, including poor decision-making and reputational damage. In exploration and early-stage sampling, CRMs are used to validate geochemical data quality, while during mine operations, they aid in grade control, ensuring the effective monitoring of ore quality. These materials are also critical for accurately characterizing ore deposits and confirming laboratory performance through proficiency testing. By choosing OREAS Certified Reference Materials, customers gain peace of mind, knowing their practices and products comply with all relevant specifications and regulatory requirements, reinforcing OREAS's position as a trusted partner in the mining industry.
