Mineralization Comments

Sep 26, 2017 (R Tuomi) - Best intersection from the 1968 DDH returned 0.07% Cu over 1.2 m.


Nov 23, 2017 (Therese Pettigrew) - A grab sample of malachite-stained talcose sericite schist locally occurring gin the shear zone that strikes southeast through Cameron Lake was collected by Kaye (1973) and returned an assay of 0.16% Cu and a trace of gold. Copper and nickel mineralization occurs in rhyolite flows and tuff bands. Assays from the 1968 drill hole include 0.07% Cu over 4 feet, and 0.03% Cu and 0.02% Ni over 5 feet.
