Centre Lake Mine


Owned by Macassa Gold Mines, Ltd., Bicroft Division.

In pegmatite dykes cutting biotite gneiss and amphibolite.

"This mine was the second largest producer of uranium in the Bancroft area.

"The deposit was discovered in 1952 by G.W. Burns of Peterborough. Centre Lake Uranium Mines Limited began exploration of the deposit in 1953. By 1955 when the company was amalgamated with Croft Uranium Mines Limited to form Bicroft Uranium Mines Limited, exploration work consisted of surface cuts, a 53.4-m adit and a 71.4-m shaft. The newly formed company erected a mill, sank another shaft to a depth of 562 meters and brought the mine into production in 1956. From then until operations were terminated in 1963, 2,016,693 kg of U3O8 were recovered from 2,233,055 tons of ore."
