The
Echo Bay Mines Limited company was organized in 1964 to develop a
silver deposit at
Great Bear Lake,
Northwest Territories, which became known as the Echo Bay Mine. The company leased the old
Port Radium settlement from
Eldorado Mining and Refining Limited and used the old camp and mill to recover silver and
copper values. Production in the Echo Bay workings ceased in 1975. The company then reopened the old Eldorado Mine workings and produced more silver and copper until 1981 when low silver prices closed the mine for good. Echo Bay Mines Limited was busy opening a new gold mine by that point -
Lupin Mine, in what was then the
Northwest Territories and is today in
Nunavut. It entered production in 1982. Echo Bay Mines Limited developed numerous other properties mostly in the
United States, including the McCoy/Cove and Round Mountain mines in Nevada, and the Kettle River mine in Washington. Corporate headquarters were in Englewood Colorado.
The company became a subsidiary of Kinross Gold Corporation in 2003 and has been delisted from the stock exchange.
