From abstract: A radioactivity survey of the Black Rock district in southern Yavapai County, Ariz, disclosed anomalous radioactivity in several localities, chiefly at the Abe Lincoln mine in sec. 11, T. 8 N., R. 3 W., about 14 road miles northeast of Wickenburg. The Abe Lincoln vein system occupies a fault zone which strikes N. 500 E. and dips from 780 to 870 NW. Moderate radioactivity is present at the Bracken property and at several other localities in the Black Rock district. The writers recommend re-opening the Abe Lincoln mine to permit a more extensive examination of the vein.

Abstract: Reconnaissance mapping in the Ruby Quadrangle, Arizona, indicates the existence of a complex assemblage of volcanic rocks and associated sediments, divisible into a younger and older series.

Abstract: Reconnaissance of Red Rock Valley was begun on December 10, 1953, and completed on February 11, 1954. The mines in the region were investigated and all exposures of Salt Wash were walked. Paleostream directions and alterations of the sandstones were observed and recorded on a base map. No important new mineralization was discovered-and the area is considered to be of no commercial significance if judged by the outcrops alone. However, a vast amount of Salt Wash lies at slight depth directly to the east of the investigated area.

Abstract: From December 1953 to May 1954 an extensive airborne reconnaissance program was conducted in northwestern Arizona (Arizona Strip) and southwestern Utah. Five surface anomalies were detected, one of which has possible commercial value. All anomalies are within the boundaries of National Park Service jurisdiction, consequently, this report is not for public distribution until clearance is obtained from the National Park Service. A preliminary airborne reconnaissance program was also conducted in the Richfield area. No anomalies were discovered.

Abstract: A study, consisting of field and laboratory work, was undertaken in an endeavor to establish possible structural mineralization controls associated with the copper-uranium occurrences in the Willaha area, Coconino County, Arizona. Uranium mineralization, apparent at present, is localized along small fissures and vugs and in certain beds and lenses of the middle member of the Kaibab formation(Permian). It is associated with copper and iron oxide staining. Though no definite ore controls were disclosed by this study, at least a limited program of shallow drilling is warranted on the property. This sub-surface exploration should determine possible extensions of known mineralized areas, explore surface radiometric anomalies, and provide data for the determination of possible guides to ore. Deeper exploration may encounter mineralization in other horizons of the Kaibab limestone.

Introduction: The purpose of this report is to describe certain significant features of the stratigraphy and sedimentation of the Salt Wash sandstone at Cove Mesa, Carizzo Mountain district, Apache County, Arizona.

Report discussing uranium oxides, their thermodynamic relations, and how these relations connect to the oxidation states of uranium ores found at the Colorado Plateaus. This report provides information regarding thermodynamic properties of some compounds and ions of the U-O-H2O system, discussion and interpretation of thermodynamic properties, and a summary with conclusion.

Report discussing the Shinarump Conglomerate, the channels leading to this conglomerate, and the uranium minerals which localize at the base of this conglomerate via the channel sediments. The geology of the area, information on the channels, and information regarding the localization of uranium in channels are included.

Letter from Dan Oppenheimer to Harris Leon Kempner discussing about the memorandum that was sent which contains the recent telephonic conversation between Mr. Mehan and J. C. Wilson. Dan discusses about the carry-back tax loss that Mr. Mehan needs to take care at Pecos, and his suggestion in appointing caretakers for the Rancho Rio and Grandfalls farms, and also, on expenses incurred with land ownership and maintenance and the future prospects from it. Finally, concludes with his high opinion on Jesse and his travel plans to Tucson.
