Hatch Point Mining District
The Lockhart Canyon (Hatch Point) district is in the Moab U mining area of northernmost San Juan County, just east of the Colorado River and about 14 mi southwest of Moab. The initial discoveries were made in the 1950s and the district became a minor U producer. Total district metal production at modern metal prices is estimated at $47,000. The Colorado underground mine was the largest producer, but it was a small operation. There is little published literature on the district.
The Lockhart Canyon district is situated in the Paradox Basin on the Colorado Plateau. The mines are geologically positioned on an unnamed east-northeast-trending syncline between Shafer dome to the north and Lockhart anticline to the south.
Lockhart Canyon U mineralization is primarily hosted in the Upper Triassic Moss Back Member of the Chinle Formation with some U occurrences in the Lower Permian Bogus Tongue Member of the Cutler Formation (USGS Model 30c). The mineralization in the Chinle is localized in Moss Back channel sandstones cut into the underlying Moenkopi Formation. Mineralization is associated with carbonaceous debris in the channels having average grades of 0.25% U3O8 and just 0.04% V2O5. The primary ores are typically uraninite, pyrite, chalcopyrite, and bornite with rare galena and sphalerite. The ore is reportedly anomalous in Ag, Ba, Co, and Cu (Doelling, 1969, 1974).
