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

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.
