Aug 07, 2012 (A Wilson) - The host rock is fine- to medium-grained olivine gabbro with sporadic pods of melanocratic material. The gabbro intrudes argillites of the Rove Formation. The property is underlain by sub-horizontal greywackes and shales of the Rove Formation crosscut by a northeast trending vertical dipping diabase dike. The greywacke is grey to grey brown, fine- to medium-grained massive and contains carbonate filled fractures. The shale is black to dark grey, fine- to very fine-grained, massive and finely bedded. The sedimentary bedding ranges form centimeter to tens of centimeters in thickness. The greywacke locally exhibits graded bedding indicating tops to be upward. The diabase dike rangesfrom black to dark grey fine- to medium-grained with minor pegmatitic sections. The contact of the diabase dike to the sediments is a hybrid zone of disrupted sediments either as fragments within the diabase or amphibole facies metamorphic grade greywacke.

Aug 07, 2012 (A Wilson) - Grab samples collected by geologists from the ODM assayed 0.72% Cu and 0.07% Ni; 0.19% Cu and 0.06% Ni. Sulphide mineralization within the dike ranges from 1% fine-grained disseminated pyrrhotite to 40% irregular immiscible blebs of pyrrhotite with 1% chalcopyrite on fracture planes within the pyrrhotite. Samples collected from the vicinity of the old trench by staff of the Thunder Bay Resident Geologist office assayed: 0.04% Cu and 0.17% Ni; 0.33% Cu and 0.12% Ni; 0.50% Cu and 0.24% Ni; 0.32% Cu and 0.10% Ni.
