OSTI ID:6033945

The Crownpoint Sec. 29 deposit, located in the west-central part of the Grants mineral belt, represents a relatively recent uranium discovery in the Westwater Canyon Member (Jurassic) of the Morrison Formation. This deposit, estimated as containing up to 10 million pounds of uranium oxide, occurs in four vertically separate sandstone units. The average depth of the ore mineralization is approximately 2,000 ft (610 m) below the ground surface. Present-day structure of the Crownpoint Sec. 29 area is relatively simple and consists of gentle north-northeast-dipping strata with no known faulting. This deposit is located in an east-southeast-trending Westwater Canyon depocenter, whose course is believed to have been influenced by subtle Jurassic structure, which was penecontemporaneous with sedimentation. The deposit has been delineated by drilling on 200-ft (60-m) centers, involving approximately 348 holes and is awaiting shaft sinking and mine development.
