In January 1964 a drilling program was initiated in and near the Gas Hills of eastern Fremont County, Wyo. The project, which was completed in May 1954, was the first exploratory drilling in the Wind River Basin since the original uranium discovery waa reported in the fall of 1953. A totel of 158 holes with an aggregate footage of 14,800 feet were drilled to explore ten separate areas for uranium and stratigraphic information. Most of the drilling was limited to the Wind River formation of Eocene age, but a few holes were planned to test the Morrison formation of Jurassic age and the Thermopolis formation of Cretaceous age. Seven areas were barren, and uranium minerals were found only in the coarse, fluviatile strata of the Upper Wind River formation. The deposits contain meta-autunte and earthy yellow uranium phosphates, which occur as interstitial fillings or as pebble and fracture costings. These minerals are not in radiometric equilibrium. Other uranium phosphates, carbonates, and arsenates are known to be present. A study of the minerelogy of the deepest ores has not been completed. Rotary, noncore drilling is suitable for general exploration in the Gas Hills area. Future exploration, based on geologic as well as radiometric guides, should be successful. (auth)
