Madawaska mine
From Wikipedia, the free encyclopedia
The Madawaska Mine was an underground uranium mine near the town of Bancroft, Ontario which produced 9,492,171 pounds of U3O8 during its two periods of production. From 1954 to 1964 it operated as the Faraday Mine, and after it reopened as the Madawaska mine in 1975, production continued to 1982.
The shaft into the uranium-bearing pegmatite reached a depth of 473m (1,537 feet).
The mine is currently decommissioned, and a mass of 4,000,000 tonnes of uranium tailings remains at the surface at the mine site.
