Dec 02, 2014 (Mark Puumala) - The following geological description of the Commerce Nickel East occurrence is excerpted from OFR 6285: The serpentinized ultramafic rock generally has a bleached grey-white colour on weathered surfaces and is green on fresh surfaces. In places, the serpentinite contained anastomosing centimetre-scale seams of magnetite. This magnetite was formed as a result of the serpentinization process and the seams generally strike easterly, approximately parallel to the regional structural trends. Magnetite in the Puddy Lake ultramafic intrusion had previously been reported to be nickeliferous (Whittaker 1986; SR 055). This was confirmed by assay data for a grab sample of magnetite-rich material that was collected during this site visit at UTM Zone 16, 319433E, 5537918N (Sample MP-12-010), which returned 5954 ppm Ni. This sample also contained anomalous concentrations of precious metals (642 ppb Au, 123 ppb Pd, and 130 ppb Pt; Resident Geologist’s Files, Thunder Bay South District, Thunder Bay).
