Nov 12, 2014 (K R Kettles) - The occurrence is underlain by metasedimentary units (greywacke, argillite,chert) which overlie massive to foliated mafic flows. Two chert units, separated by a thin lense of argillite, returned the best assays. The chert contained approximately 2 to 3% pyrite, and 1% pyrrhotite in blebs, disseminations and fracture fillings, and up to 40% pyrrhotite in brecciated zones.
