From introduction: The Geology Department of the University of Wyoming was asked to make a geostatistical assessment of the uranium endowment of these deposits as a part of the World Class core drilling operations of the Bendix Field Engineering Corporation. This study was to include (a) the development of optimum geostatistical methodology for assessing uranium endowment in areas of close drill control (1 mile or less centers) as well as in areas of distant drill control (5 mile centers or more), (.b) the implementation of this methodology in assessing the uranium resources of the pebble conglomerates in southeastern Wyoming, and (c) the determination of the overall geostatistical uncertainty of the resource estimates. In addition, methods were to be studied for projecting the assessments into new areas, including prediction of estimate uncertainty.

Maps show drilling plans in four areas of the the Silver Cliff Mine in Lusk, Wyoming.

"The principal uranium deposits in southcentral Wyoming and north-western Colorado are located in or at the margins of broad Tertiary basins. Interesting and possibly commercially significant occurrences are found in other Tertiary and older rocks at widely separated locations within this region. The six maps accompanying this report give the location, name, and ownership of the mines and occurrences from which samples assaying greater than 0.10% U3O8 have been collected. Claim names, location, and ownership are also given for occurrences outside the map areas."

Abstract: Uranium was discovered in the Gas Hills of the Wind River Basin by Mr. Nail E. McNeice of Riverton, Wyoming while he was prospecting with a Geiger counter in September 1953. Field parties of the Atomic Energy Commission started work in the area in October 1953.

Introduction: This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the nine holes drilled in the Great Divide Basin project during the 1981 drilling program. General information is presented regarding specific problems including weather and logistics. A separate geologic report is being prepared and will be available through the Bendix Field Engineering Corporation Technical Library in the near future.
