Port Radium is a mining area on the eastern shore of Great Bear Lake, Northwest Territories, Canada.[1][2] It included the settlement of Cameron Bay as well as the Eldorado (also called Port Radium) and Echo Bay mines. The name Port Radium did not come into use until 1936 and at the time it was in reference to the region as a whole. The Eldorado mine site at LaBine Point adopted the name for its settlement in the 1940s and it has generally stuck.
