Aug 02, 2017 (A Wilson) - Keewatin volcanics striking northwest are intruded by Nipissing quartz-diabase sill. Thickness of overlying Keewatin remnant is 50’ and of the sill 1100’. Northeast corner of claim is crossed by northwest-trending, O’Brien-Violet fault. Two vein systems exist: those with northwest strike that were productive within proximity of lower contact of sill and associated with faults; those veins with northeast strike that parallel the axis of the Peterson lake diabase basin and were productive within proximity of the upper contact.
