Ore is hoisted from l)oth shafts by steam hoists. A small Ingersoll-Kandsteam-driven compressor supplies air for three drills. The mill is driven hy Goldie and McCulloch, Wheelock condensing engine. The boiler plantincludes one and one return tubular boiler. Eock is hoisted from the mine by a skip at No. 1 shaft and a cage at No. 2and dumped into ore bins. From the bins it passes over a grizzly to a Championjaw crusher, followed by a Sturtevant fine crusher. The ore then passes througha steam dryer and a pair of Sturtevant rolls to the tube-mill bins. It is ground.

Four grades are turned mill has a capacity of 100 tons per day. Products are sold to Canadian trades,but the greater part of the output is shipped to the United States. A waterpower plant is being installed on the Moira river, which passes throughthe property within 200 feet of the mill. The plant comprises a concrete dam withstop-log sluice and flume; two little giant turbines and the necessarytransmission shafting, gears, etc., to carry power from the wheels direct to the mill. A second mill, to grind gratalc, a special product obtained from a largedeposit of dark grey talc lying east of the white deposit, is being erected inconnection with the powerhouse.
