Charles LaBine was born in 1888 at Westmeath, a small community in the Ottawa Valley near Pembroke, Ontario. Charles was the elder brother of Gilbert LaBine. After working for several years in the silver mines of northern Ontario, Charles and Gilbert LaBine began prospecting for themselves. They founded Eldorado Gold Mines Ltd. in the 1920s following the discovery of gold in Manitoba. Charles LaBine was responsible for managing the financial aspects of the mining operation. Though Eldorado Gold didn’t succeed as hoped, it provided the LaBine brothers with the finances needed mto conduct further prospecting activities.
Investigating the mining potential around Great Bear Lake that had been documented by James McIntosh Bell of the Geological Survey of Canada, the LaBine brothers began prospecting along the shores of Great Bear Lake. In the spring of 1930, Gilbert LaBine discovered a deposit of pitchblende, another name for uranium ore. The discovery was made on the shore of Echo Bay. The development of a viable mining operation faced significant financing and logistical challenges, as the mine was more than 2000 km from the nearest railway. Although Charles was not with Gilbert when the pitchblende was found, it was his job to follow up and solve the financing and logistical problems of moving equipment to the mine site and the ore south for processing. In order to finance the development, the LaBines mined the silver that lay in the same area of Great Bear Lake.
The operation began as a radium mine in 1932, extracting radium from pitchblende. Mined materials were shipped by barge and air plane to Fort McMurray, Alberta, then by train to a radium refinery in Port Hope, Ontario. The company secured a contract with the United States military early in 1942. The Eldorado Mine at Port Radium was transferred to the Canadian Government in 1944 and renamed Eldorado Mining and Refining Limited. Uranium ore from the mine was used in the atomic bomb developments of 1945.
In the 1950s, uranium was discovered along the shores of Lake Athabasca. There the Labine brothers founded Gunnar Mines, the first Canadian producer of uranium that returned a profit to its shareholders. Gilbert was president and Charles the vice-president of Gunnar. Charles retired from the management in 1955.
The contribution of the LaBine brothers to the advancement of medical science as a result of their work was recognized at home and abroad. The brothers received the Curie medal from the governing body of the International Union Against Cancer. The citation accompanying the medal to Charles LaBine said that the Pierre and Marie Curie medal, which had been struck in 1938 on the occasion of the 40th anniversary of the discovery of radium, was conferred upon him “for the distinguished services that you have rendered to science and to humanity.” Charles LaBine died in 1969 at the age of 81.
