Report summary

Since the privately-owned company Montana Resources Inc. re-opened the mine in 2003 copper and molybdenum concentrates have been produced from ore mined from the Continental pit.  Additional copper precipitate production is derived from water pumped from the Berkeley pit that was previously mined between 1955 and 1982.
