OREAS 49
SKU: 49
OREAS 49 is sourced from glacial till from the Rainy River District, with
minor additions of ore materials (Base Metals, PGEs, REEs, and Li) to achieve
anomalous concentration levels. A pure glacial till is also available (see OREAS 48). This till,
predominantly of Late Wisconsinan age, is typically classified as an unsorted
diamicton. Its composition reflects both the local Precambrian Shield bedrock
including granitoid rocks, metavolcanics, and metasedimentary rocks, and
Paleozoic sedimentary formations. The material contains a mix of felsic to mafic
lithologies with mineral constituents such as quartz, feldspar, amphibole, and
biotite, along with occasional sulphide minerals. The till’s combined local and
long-range glacial provenance makes it a reliable matrix for geochemical
exploration, particularly for QAQC applications targeting anomalous
concentrations of gold, PGE, REE, lithium, and base metals.
Twenty commercial analytical laboratories participated in the program to
certify the elements reported below:
Gold by 15-50g fire assay with ICP-OES, ICP-MS or AAS finish
Gold by aqua regia digestion (10-50g sample weight) with ICP-OES,
ICP-MS or AAS finish
Lithium borate fusion or sodium peroxide fusion for full ICP-OES and
ICP-MS elemental suites
Full ICP-OES and ICP-MS elemental suites by 4-acid (HNO3-HF-HClO4-HCl)
digestion
Full ICP-OES and ICP-MS elemental suites by aqua regia digestion
To confirm homogeneity, the repeatability of gold was evaluated using high
precision INAA.
