Bancroft continues to be known for gems and mineralogy, and has three decommissioned uranium mines and one that is undergoing rehabilitation. Mining resumed when uranium prices rose during the 1970s energy crisis, but this was not long lasting. : 1 By 1963, the federal government had purchased more than $1,500 million of uranium from Canadian producers, but soon thereafter the global supply of uranium increased, prices fell and the government cancelled all contracts to buy. By 1958, Canada had become one of the world's leading producers of uranium the $274 million of uranium exports that year represented Canada's most significant mineral export. Mining activities were conducted during two periods, 1956–19–1982, when uranium prices made underground hard-rock mining of the ores economically viable.Īs a result of activities at its four major uranium mines, Bancroft experienced rapid population and economic growth throughout the 1950s. Bayne in a 1977 report as the "greatest uranium prospecting rush in the world". Activity in the mid-1950s was described by engineer A. S. In the context of mining, the "Bancroft area" includes Haliburton, Hastings, and Renfrew counties, and all areas between Minden and Lake Clear. Uranium mining in Bancroft represents one of two major uranium-producing areas in Ontario, and one of seven in Canada, all located along the edge of the Canadian Shield.
