Uranium mining in the Elliot Lake area
Uranium mining in the Elliot Lake area (prior to 1955, more commonly known as the Blind River area) represents one of two major uranium-producing areas in Ontario, and one of seven in Canada. In the mid-1950s, the influx of people to Elliot Lake seeking uranium was described by engineer A. S. Bayne in a 1977 report as the "greatest uranium prospecting rush in the world".
