The Lac Windfall Mine Project would have an ore production capacity of approximately 1,900 tonnes per day over a period of up to 10 years. Additional project components would include an ore processing plant, a tailings pond, ore, waste rock and overburden storage areas, two operating ramps and the widening of a bridge.
