Abstract: A four-week reconnaissance of certain portions of the mountainous area in Gila and Pinal Counties, Arizona, was undertaken in March and April, 1953, to inspect accessible outcrops of Dripping Spring quartzite, a pre-Cambrian formation which has lately attracted the interest of the Atomic Energy Commission by the discovery of two separate occurrences of uranium mineralization. Although no new deposits were found during the field work, a more thorough examination of the quartzite seems warranted. Recommendations for further prospecting by airborne and ground methods are presented in this report, and are based largely on observations made during the brief visit.

This book presents reconnaissance reports for uranium deposits in Mohave County, Arizona from 1952 to 1956.

Introduction: A radiometric airborne reconnaissance of the Cameron, Arizona, district was conducted in the late fall of 1952 and early winter of 1953. Flying was carried out under the direction of the Salt Lake Exploration Branch of the Atomic Energy Commission, Division of Raw Materials. Airborne equipment and ground personnel were provided through the Technical Services Branch of the Grand Junction Exploration Division.

Abstract: Preliminary studies of the Wallapai Mining District and selected properties in the Maynard and Greenwood Mining Districts, Mohave County, Arizona, from January 8 to March 8, 1953, were made to determine the extent of uranium mineralization. All of the uranium properties examined are of the vein type and are believed to be of mesothermal origin. Brecciation and porosity of the veins appear to be controlling factors in the concentration of uranium minerals from the ore-bearing solutions. Although the uranium minerals present in these districts have not been specifically identified, they appear to be mostly primary with very minor occurrences of secondary products. One exception is the State mine in the Greenwood District, where secondary minerals predominate.

Abstract: On July 16, 1953, a diamond core-drilling program was begun in the Pumpkin Buttes area to secure geologic information.

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.

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

Abstract: An airborne radiometric survey of the Dakota sandstone and Morrison formation in the Canon City embayment was conducted by the Atomic Energy Commission from November 1, 1953 to December 5, 1953.

Abstract: On March 7, 1953, after approximately three and one-half months, investigational drilling in the North Point No. 6 and Horn channels was completed.

This document reports a preliminary airborne reconnaissance survey that was conducted in the mountain ranges of the northwest portion of Nevada.

Discussing water samples collected during a reconnaissance study for uranium, and the analysis of the samples.

This report provides the results to an airborne radiometric reconnaissance made in central Montana, the Sweetgrass Hills and Arch area, and Clancy area of the Boulder batholith that was completed in October 1953. This report is divided into three parts, each area is discussed separately according to its geology, the airborne procedures employed, and the conclusions reached.
