After a long hiatus, our popular Canadian glacial till CRMs are back. Introducing OREAS 48 and 49, the updated replacements for OREAS 46 and 47.
Sourced from glacial till in Ontario’s Rainy River District, these materials reflect a diverse geological mix of Precambrian granitoids, metavolcanics, metasediments, and Paleozoic sediments, capturing a wide range of felsic to mafic lithologies.
OREAS 49 is enhanced with trace additions of ore materials (base metals, PGE, REE, and Li) to provide elevated, anomalous levels. This combination of local and long-range glacial inputs makes them ideal for QAQC in geochemical exploration targeting background levels of gold, base metals, lithium, REE, and PGEs.
