F-33 Uranium Mine Closure

Site History

The F-33 Mine is an underground uranium mine that operated from 1954 to 1959. The mine is in the Grants Uranium District in Cibola County, New Mexico. The primary commodity extracted was uranium with vanadium, fluorine, and barium as secondary products. The mine is located on private land and was operated by the Anaconda Company. At the time of characterization, the remaining evidence of the five-year production run included waste rock dumps, vertical vent raises, open adits, and miscellaneous debris from frames and buildings used during the mining activity.
