In 1949,
athabascaite was discovered by S. Kaiman while he was researching
radioactive materials around Lake Athabasca near Uranium City. In 1952, the provincial government decided to establish a community to service the mines in the
Beaverlodge uranium area developed by
Eldorado Mining and Refining, a federal
crown corporation. In 1954, the local newspaper,
The Uranium Times, noted that 52 mines were operating and 12
open-pit mines were next to Beaverlodge Lake. Initially, most of the residences in Uranium City were simply tents. Some of the
mines operating in the area included the
Gunnar Mine, the
Lorado Mine, and the Fay-Ace-Verna Mine in
Eldorado, Saskatchewan. Two options were considered for communities in the region: small communities near the mine site or larger more centralized communities with adequate services. Not wanting to replicate some of the problems associated with small mining towns at the time in
Northern Ontario, the government pushed for the second option and modelled Uranium City after the community of
Arvida, Quebec. In 1956, the provincial government passed the
Municipal Corporation of Uranium City and District Act, creating a unique, chartered "district" with authority over education, health, and welfare. The population of Uranium City started to grow significantly only once Eldorado Resources made a deliberate initiative in 1960 to see staff housed in Uranium City instead of the
Eldorado campsite. The local hospital closed in the spring of 2003. Its population in 2016 was 73,{{cite web | title = Census Profile, 2016 Census | url =http://www12.statcan.gc.ca/census-recensement/2016/dp-pd/prof/details/page.cfm?Lang=E&Geo1=DPL&Code1=470239&Geo2=PR&Code2=47&Data=Count&SearchText=uranium&SearchType=Begins&SearchPR=01&B1=All&TABID=1 == Demographics ==
