Echo Bay Mines

Echo Bay Mines Limited is a Canadian company which was organized in 1964 by Northwest Explorers Limited to develop a silver deposit at Great Bear Lake, Northwest Territories,Canada, which had been staked in 1930 by tne Canadian Mining and Smelting Company.^[2] 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 from what became known as the Echo Bay Mine. 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.
