QUEBEC – Montreal-based Osisko Mining has chosen a site near Lebel-sur-Quevillon for the future mill that will treat ore from the Windfall Lake gold project. Information about the proposed location will be used as the company prepares an environmental assessment and a feasibility study for the Windfall project.
If the site in Lebel-sur-Quevillon is chosen to process ore from the Windfall Lake project, the mill could serve several other gold mines in the region.
The site is near the former Domtar pulp and paper mill, about 11 km from the town and 103 km via existing all-weather gravel roads from the mine site. There are a Hydro-Quebec substation and a water pumping station adjacent to the property. The land is owned by the Crown, but Osisko holds the mineral rights.
Osisko cites several reasons to choose the Lebel-sur-Quevillon site rather than build a mill at the mine site:
- Limiting Windfall Lake infrastructure to underground mining activity greatly reduces the environmental footprint.
- Access to existing grid power and the Hydro-Quebec electrical substation will eliminate the construction and costs of a 103-km power line to Windfall Lake as well as the corresponding environmental permitting along the power corridor.
- The existing water pumping station has ample capacity for a gold milling complex.
- Having a regional work force at Lebel-sur-Quevillon reduces the need for a large construction and operations camp at Windfall Lake, and the rotational work force will be reduced.
- The cost savings on transportation and construction/operations logistics from existing rail and road access to Lebel-sur-Quevillon will offset the cost of transportation of ore.
- There is also the potential for the mill to treat ore from other gold deposits within trucking distance of Lebel-sur-Quevillon.
