Introduction: This study was made in conjunction with a core drilling program designed to trace ore trends from existing mines eastward under deeper cover. The exploration drilling covered an area of about 1 square mile. The results of previous drilling by the Commission, which covered an additional 10 square miles, have been incorporated in this report.

Abstract: The Wilson Creek Area, in northern Gila Cointy, is about 10 miles southeast of Young, Arizona, along the east side of Cherry Creek. Four claims covering concentrations of uranium mineralization in the Dripping Spring Formation are owned by the American Asbestos Cement Company. The claims are located in typical plateau-type topography, with flat mesa* and nearly vertical canyon walls. The bedded zones of uranium mineralization are exposed in the Dripping Spring Quartzite near the bottom of the canyons. It is suggested that the mineralized beds may have spatial relationship to the bottom of the Mescal limestone and to the bottom of a thick zone in the upper member of the quart site. Two of the four bedded deposits occur in *crackled" beds. One mineralized fracture was noted. The uranium mineral, meta-torbernite, has formed in tiny vugs in the quart site and is also intergrown with the iron oxide coating on the quart site surfaces. Associated minerals are minor and consist of chalcopyrite magnetite and chalcocite.

Abstract: This report consists of four parts, the first three being descriptions of investigations compiled in the period October 1st, 1953 to April 1st, 1954; the fourth part is a summary of progress of the research based on our entire investigations completed prior to April 1st, 1954. The first part comprises a set of preliminary experiments investigating the mineral composition of the sandstones in thin sections, in an attempt to differentiate barren from ore-bearing sandstones. It appears that there are more rock-fragments and particularly more volcanic rock fragments in the ore zone (zone 4, Well C, Bull Canyon). In addition, silica cement appears to be associated with ore and carbonate cement with barren sediments. The second part details the investigation of the mudstones of the Bull Canyon Wells . A mixed layer lattice "illite" and a kaolin mineral are the most prominent in "normal" mudstones. Dye tests suggest there are differences between the clay minerals in the sandstone matrix of the ore zone and barren zone. In addition, the mudstone zones appear to differ in the response to the dye tests. The third part of the report details the bulk density determinations for cores from well B. The results confirm …

Results of a survey in the southwest segment of the Zuni Uplift sedimentary formations. It includes an overview of physical geography in the area, as well as economic geography, including mineral deposits.

Discussing evidence of the potential of uranium in Libya

From purpose and scope: This report is designed to summarize the available information on the geology and ore reserves of the uranium deposits. Detailed geological work has been confined largely to those areas which contain the more promising uranium occurrences with at least 80 percent of such work being concentrated in the Sierra Ancha district.

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.

Record of the results of the petrographical investigations of the Salt Wash Sediments

Abstract: Concentration of secondary uranium minerals, some of which are commercially significant, have been found in three formations of Tertiary age in the Gulf Coastal Plain area of southern Texas: the Fayette sandstone of the Jackson formation, the Catahoula tuff, and the Oakville sandstone.

Summarizing the findings of investigations of radiometrically anomalous areas and discussing recommendations for a diamond drilling program.

Abstract: An area of high anomalous radioactivity and visible uranium minerals is associated with a nearly vertical north 70° west trending shear zone.

A report discussing a study made of the Hite Section of the Glen Canyon Dam Immersion area to evaluate uranium occurrences and potentials.

Abstract: A program of airborne radiometric reconnaissance for uranium was conducted in eastern Fremont and western Natrona Counties, in central Wyoming, during the summer and fall of 1954, by the U.S. Atomic Energy Commission.

Report discussing initial ventures in a joint project between the United States Atomic Energy Commission and the Comision Nacional de la Energía Atomica of Argentina (CNEA) to examine existing uranium deposits in Argentina and determine the best course for new prospecting programs. This document outlines the findings for specific locations visited in Argentina and their relative importance.

The general purpose of the work performed under this contract was to develop geophysical and geochemical methods and techniques which would be effective aides in exploring for uranium and to appraise their effectiveness as determined by the results of field surveys in prospective areas about to be drilled, or in an area where ore is already known.
