6061ppm Sn + 324ppm Bi + 2453ppm Cu (smectite clay) OREAS 141 - 10g

CAD$3.90 each

OREAS 141 is a medium grade Sn oxide ore certified reference material (CRM) prepared by Ore Research & Exploration. The material was sourced from the Doradilla Project located in north central NSW. The project area consists of a large Sn laterite deposit underlain by Sn silicate skarn with potential for copper, nickel, indium and zinc mineralisation. The skarn horizon has a strike length of 16km with zones of oxide, supergene and primary Sn mineralization. Compositionally OREAS 141 is dominated by smectite clay with minor quartz, kaolin and goethite. Sn mineralization occurs as varlamoffite [(Sn,Fe)(O,OH)2] with some relict cassiterite. OREAS 141 is one of three tin CRMs prepared from oxide material and characterised for Ag, As, Bi, Cu, In, Mo, Pb, Zn and Sn.
