The Athabasca Basin is a region in the Canadian Shield of northern Saskatchewan and Alberta, Canada. It is best known as the world's leading source of high-grade uranium and currently supplies about 20% of the world's uranium. On the northern and eastern edges are the communities of Fort Chipewyan in Alberta and Camsell Portage, Stony Rapids, Fond du Lac, Black Lake and Wollaston Lake in Saskatchewan. Much of the Athabasca Basin is within the migratory range of the Beverly caribou herd a major source of sustenance for the Denesuline communities.

  • The Athabasca Basin is a region in the Canadian Shield of northern Saskatchewan and Alberta, Canada. It is best known as the world's leading source of high-grade uranium and currently supplies about 20% of the world's uranium. The basin is located just to the south of Lake Athabasca, west of Wollaston Lake, and encloses almost all of Cree Lake. It covers about 100,000 square kilometres (39,000 sq mi) in Saskatchewan and a small portion of Alberta. The surface of the basin consists of main sandstone sediment varying from 100 to 1,000 metres (330 to 3,280 ft) in depth. The uranium ore is mostly found at the base of this sandstone, at the point where it meets the basement. On the northern and eastern edges are the communities of Fort Chipewyan in Alberta and Camsell Portage, Stony Rapids, Fond du Lac, Black Lake and Wollaston Lake in Saskatchewan. Much of the Athabasca Basin is within the migratory range of the Beverly caribou herd a major source of sustenance for the Denesuline communities. Within the basin are the Athabasca Sand Dunes Provincial Park on the south shore of Lake Athabasca and the Carswell crater. The Cluff Lake mine site is located in the crater area. Points North Landing, a permanent supply depot and camp, serves the eastern area of the basin. Road access to the area is provided by Saskatchewan Highway 955 from the village of La Loche on the west side and Saskatchewan Highway 914 and Saskatchewan Highway 905 north of the town of La Ronge on the east side.

  • Le Bassin sédimentaire de l’Athabasca est une subdivision du Bouclier canadien s'étendant au nord de la Saskatchewan et de l'Alberta. C'est l'une des principales sources d'uranium de haute pureté : il fournit en 2020 20% des ressources mondiales en uranium. Ce bassin s'étend juste au sud du lac Athabasca, à l'ouest du lac Wollaston et recouvre presque entièrement le lac Cree. Il occupe une superficie de 100 000 km2 dans la province de Saskatchewan et une petite partie de l'Alberta. C'est un dépôt de sédiments grèseux, dont l'épaisseur varie de 100 à 1 000 m. Le minerais d'uranium est principalement piégé à la base de ce grès, à l'interface du substratum. Le nord et l'est comporte quelques bourgs et villages : Fort Chipewyan dans l'Alberta ; , , , et en Saskatchewan. La plus grande partie de cette plaine se trouve sur la route de migration du troupeau de caribous de Beverly, source de subsistance pour les communautés Denesuline. Le parc provincial d'Athabasca Sand Dunes occupe la rive sud du Lac Athabasca et le cratère de Carswell, où se trouve la mine de Cluff Lake. L'aérodrome de Points North Landing, à l'est du bassin, constitue un dépôt d'approvisionnement pour la région. L'accès par la route se fait par l'autoroute provinciale 955, qui relie le village de La Loche, à l'ouest, et les autoroutes 914 et 905, qui passent au nord de La Ronge à l'est. (fr)
