Makwa


A copper-nickel property located 160 km NE of Winnipeg in SE Manitoba.
1976: Maskwa Nickel and Chrome Mines (MNCM) Mined 332,000 t averaging 1.16% Ni and 0.20% Cu by open pit. Ore was trucked to Gordon Lake, Ontario for milling.

1969-1973: MNCM: Entered into an agreement with Consolidated Canadian Faraday Limited to mine the nearby Dumbarton deposit and the F-Zone, which produced approximately 1,540,000 t of ore averaging 0.81% Ni and 0.30% Cu. Ore was trucked to Gordon Lake, Ontario for milling.
