Geological Investigation of Mexican Cry Mesa, Lukachukai District, Arizona with Diamond Drilling Recommendations

Abstract: The Salt Wash member of the Jurassic Morrison formation of Mexican Cry Mesa, Lukachukai District, Arizona, was examined to determine size, grade, and distribution of contained carnotite deposits and the possibilities of developing reserves by exploratory drilling. Only three occurrences of carnotite-bearing sandstone were found in 17 miles of rim outcrop. Limited drilling is recommended in the vicinity of these exposures.
