The Bluff–Butler Wash district of the Monticello U mining area is in southeastern San Juan County about 10 mi south of the White Mesa U-V mill near Blanding. The poorly documented Bluff–Butler Wash district is a small U-V producer, and total district metal production at modern metal prices is estimated at $1.6 million. The largest mines are the Hole in the Rock and Tree.
The Bluff–Butler Wash district is situated in the Paradox Basin on the Colorado Plateau. The uranium deposits of the district are generally hosted in the flat lying Upper Jurassic Salt Wash Member of the Morrison Formation; however, the Hole in the Rock mine is hosted in the overlying Westwater Canyon Member (USGS Model 30c). Mineralization is localized where permeable channel sandstones are interbedded with carbonaceous trash and mudstone lenses. The ore deposits are unoxidized below the water table and are dominantly composed of intergranular uraninite and montroseite. Ore grades in the district average about 0.24% U3O8 and 0.26% V2O5 (Doelling, 1969, 1974).
