Location

Eldorado Mine is located at Port Radium, Northwest Territories, Canada. It is also known as Port Radium, a name adopted for use at this specific site after 1942. Before 1942, the name Port Radium was used in reference to the name of the government facilities at Cameron Bay (post office and wireless radio station).

History

During a field trip along the east arm of Great Bear Lake in August 1900, James McIntosh Bell of the Geological Survey of Canada noted evidences of iron, copper, uranium and cobalt in the vicinity of Echo Bay. 30 years later, on May 16, 1930, prospector Gilbert LaBine discovered high-grade pitchblende and silver at this site. His company was then known as Eldorado Gold Mines Limited (later renamed Eldorado Mining and Refining Limited. 1900 is a common year starting on Monday. ...

The Eldorado Mining and Refining Limited company was originally organized in 1927 as Eldorado Gold Mines Limited to develop a gold mine in Manitoba. ...

Eldorado started off as a radium mine in 1932, extracting radium from pitchblende. Radium ores were highly valued at the time because the price of radium salts, used in cancer treatment and then monopolized by Belgium, was US$70,000 per gram. The first concentration plant was erected at the site in 1933, with a radium refinery built at Port Hope, Ontario. Concentrates and cobbed material were shipped by barge and air plane to rail head at Fort McMurray, Alberta, then by train to Port Hope. 1932 is a leap year starting on a Friday. ... 1933 was a common year starting on Sunday (link will take you to calendar). ...

In 1940 the mine closed because of the closure of European markets for radium. In 1939, at the beginning of World War II, ore from Eldorado had been used in the first chain reaction experiments, and as soon as the scientists had found out that these ores contained a rich store of uranium oxide and were useful as a source of nuclear energy. Gilbert LaBine's company was able to secure a contract with the United States military early in 1942. The Eldorado Mine at Port Radium was secretly expropriated and transferred to the Canadian Government in 1943-1944 and renamed Eldorado Mining and Refining Limited.

Uranium mining continued after World War II due to the Cold War Crisis. The mine was expensive to operate and grade of the ore was declining, so new technology was brought in to make the isolated mine profitable. The discarded tailings were dredged from the bay when new machinery was installed to recover the uranium values. The underground workings were deepened and the crown corporation sought out additional deposits of uranium across Canada. But in 1960 the original Eldorado Mine was exhausted and closed.

In 1976 the Eldorado Mine was dewatered by Echo Bay Mines Limited to recover old silver and copper minerals. All activity ceased in 1982 and Eldorado Mine and the Port Radium settlement was burned and demolished. Only an old log cabin remains today. In 1999 the Canadian Government signed a commitment with the Deline Dene Band to have the estimated 1.7 million tonnes of radioactive mine tailings in Port Radium cleaned up. 1976 is a leap year starting on Thursday (link will take you to calendar). ... 1982 is a number and represents a common year starting on Friday of the Gregorian calendar Events January-February January 6 - William Bonin is convicted of being the freeway killer.
