Showings : # 1- about 500 ft W are pits in the slope of a hill for 200 ft. # 2 - about 250 ft SE of the camp is a cut 10 x 10 and 5 ft deep. #3 - about 800 ft NE of the camp is a square pit 15 ft across and 20 ft deep. # 4 - the main showing is in the S half of lot 9, about 1,100 ft NE of the camp . An L-shaped group of workings consist of an open pit (100 x 10-30 x 6-15 ft deep, E-W); a small drift 50 ft E of the pit (8 ft high, 10-20 ft across and 15 ft long down-dip); to the E of the drift is an open cut (80 x 25 x 10-15 ft deep).
1919-20 : Opeongo Mica Mines Ltd (T.A.Low) originally worked the property and removed 65 tons of rough mica.
