OREAS 63

SKU: 63

OREAS 63 is a gold–silver certified reference material prepared from Cerro
Moro ores, composited from Low Ag–Au ore, with minor additions of High Ag ore
and High Au ore.
Designed for calibration and routine QA/QC of Au–Ag assay methods (fire
assay/ICP-OES-MS) and multi-element geochemical suites, OREAS 63 provides a
realistic matrix for epithermal lode-style materials.
OREAS 63 has been characterized using the following methods:

Gold via 25-50g fire assay with AAS or gravimetric finish
Silver via 25-50g fire assay with Gravimetric finish
Silver via 4-Acid digestion with AAS finish
Certified values for applicable analytes are operationally defined for each
method, with results under OREAS ISO 17034 scope of
accreditation.
