Crow Butte is a uranium mining operation located four miles (6 km) southeast of the city of Crawford in Dawes County, Nebraska, United States.
Uranium is extracted from basal Chadron Formation sandstone aquifers 400–800 feet (120–240 m) below the surface by the in-situ recovery process.
A solution of water, oxygen and sodium bicarbonate (baking soda) is injected into the orebody, which liberates the uranium from its sandstone host and allows recovery by production wells.
In 2015, the Oglala Sioux Tribe lodged six objections with the Atomic Safety and Licensing Board against the expansion of the mine's operating license to include the Marsland Expansion Area (south of the current site), claiming Crow Butte was a sacred site and within their treaty territory.
[6][7][8][9] The Crow Butte facility was originally developed by Wyoming Fuel Corporation in 1986 and subsequently acquired and operated by Ferret Exploration Company of Nebraska.
