Jun 25, 2010 (A Wilson) - The workings of the Bruce section consist of numerous shafts and openings which extend along the strike of the vein for a distance of 2300 feet and probably to a depth of 300 feet. The veins strike N30-65W and dip vertically. The main vein is characterized by horse-tailing and off shooting veinlets which penetrate the walls on either side of the main veins. Old workings may be traced along this section for a strike length of 1500 feet. The vein system is arcuate with a strike of 100° at the west end, curving to 145° at the east end

Jun 25, 2010 (A Wilson) - Total mine production from the Bruce Mines 47,593 tons of concentrates having an average grade of 20% derived from an estimated 400,000 tons mined (300,000 tons milled with 60% recovery); yielding 9850 tons of copper. The copper content of the ore is estimated to have been 4.5% Cu. There are no accurate production records for the Bruce Mines properties. Production cannot be attributed to individual sections. Total recorded shipments of siliceous ore shipped by Mond Nickel Company Limited was 161,683 tons (MRC 12, p. 53)
