Gunnar Uranium Mine & Mill Site Remediation

Located on the north shore of Lake Athabasca, approximately 25 kilometres southwest of Uranium City, Saskatchewan

Project Scope

Year: 2016–2021
Client: Saskatchewan Research Council
Project Scope Performed Under: Fond du Lac Nuna Joint Venture (FDLN JV), a partnership with Fond du Lac First Nation Development Limited Partnership

 

The mine was in operation from 1955 to 1963 and officially closed in 1964.

Fond du Lac Nuna Joint Venture (FDLN JV), a partnership with Fond du Lac First Nation Development Limited Partnership, mobilized to the Gunnar site in September 2016 to carry out a 5-year contract to reduce the risks from the abandoned site.

FDLN JV’s scope is similar to that of the Lorado project and involves remediation of 3 major tailings deposits by covering them with over 800,000 cubic metres of waste rock, 430,000 cubic metres of medium textured till, and over 280,000 cubic metres of coarse textured till. The project also involves construction of a drainage channel through the entire site, lined with riprap and armour along the entire shoreline adjacent to Langley Bay, and haul road construction. All materials used for the project will be generated from on-site borrows developed and maintained by FDLN JV.

As prime contractor, FDLN JV is responsible for all aspects of the project, including site health and safety policies, landing strip, charter flights, fuel supply and storage, and — although SRC maintains and operates the camp — owning or subcontracting all on-site equipment.
