Jul 31, 2017 (A Wilson) - Northwestern striking Keewatin rocks, cut by Haileyburian lamprophyre dikes are intruded by Nipissing diabase sill, about 1100 ft. thick. The sill forms the northwest limb of the northeast trending New Lake Diabase Basin. The northwest trending Columbus diabase dike of Keweenawan age intrudes Keewatin and Nipissing rocks. The Columbus Fault Striking NW with 60º northeast dip bisects the property. Two vein systems occur: on strikes NE, parallel to the long axis of the New Lake Basin; the other strikes at right angles to the axis. Silver-cobalt production is restricted to the northwest-trending veins particularly in the vicinity of the Keewatin-Upper Nipissing contact. Base metal mineralization occurs as disseminated sulphides in the Keewatin volcanics.
