The Eldorado Mine became the only remaining operation in the Port Radium area after 1942. Port Radium was occupied from 1942 to 1960 while the Eldorado Mine was producing uranium, then again between 1964 and 1982 when Echo Bay Mines Limited produced silver from the so-called Echo Bay Mine, and the Eldorado Mine. When the mine finally closed in 1982, Echo Bay burned down the remaining buildings with few exceptions. In 2007, the Canadian Federal government completed the remediation at Port Radium by removing all remaining infrastructure.
