Examination of Copper-Uranium Occurrences in the Willaha Area, Coconino County, Arizona

Description: 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.

Results of Diamond Drilling Mesas 1, 2, 3, and 4, Lukachukai Mountains, Northeastern Arizona

Description: From purpose and scope: Diamond drill exploration of the Lukachukai district was undertaken to find minable bodies of uranium ore and to determine whether sufficient reserves were present to warrant construction of a local mill. A minimum of 30,000 feet and a maximum of 50,000 feet of drilling were assigned to block out ore in the discovery area, Mesa I (pl. 1.). It was anticipated that some of the footage might be used to test Mesa II should the area become accessible. With access to Mesas II and IV subsequently provided by roads constructed by F. A. Sitton, Inc., and access to Mesa III furnished by a road constructed by the Atomic Energy Commission, the area available for drilling was eventually increased by some three and a half times. With no increase in allotted footage, the hole density was correspondingly decreased,

Geology of Horse Mesa, Arizona - New Mexico, with Recommendations for Wagon Drilling

Description: Abstract: Horse Mesa is in the Navajo Indian Reservation directly on the Arizona-New Mexico state line. Uranium-vanadium deposits in the Salt Wash sandstone which caps the Mesa are fairly widespread and small tonngges have been shipped from two mines. The deposits lie 60 to 75 feet above the base of the Salt Wash formation and possibly trend northwest parallel to ore trends on King Tutt Mesa, a mile northeast. Carnotite and vanoxite are the principal ore minerals. About 6,000 feet of wagon drilling is recommended to test two favorable areas. Continued exploration should be governed by results of this first stage drilling.

Preliminary Reconnaissance Work in the Rattlesnake Area, Apache County, Arizona

Description: From introduction: The Bluff-Salt Wash contact was mapped on aerial photographs. Mines and prospects were also plotted on the photos. The mines and prospects were studied and a brief description of the mineralization and its occurrence was written. These field notes, which will be given to Hatfield and party, contain data on the presence of carbon and fossil logs, lithology of the gangue rock, sedimentary structures, etc. Regional structure and evidence for igneous activity were also noted.

Geology of the Uranium Deposits of the Lukachukai Mountains Area Apache County, Arizona

Description: Abstract: In a study of the comparative importance of sedimentary and tectonic ore controls and in search of data bearing on the origin of the deposits, ten mines in the Lukachukai Mountains, Apache County, Arizona were examined in detail. All commercial deposits in the area are in the Salt Wash Member of the Morrison Formation of Jurassic age. The ore bodies are elongate and horizontally lenticular in shape and consist of one or more ore pockets surrounded or separated by protore. The composite length of ore bodies consisting of two or more ore pockets separated by subore grade material ranges up to 1,100 feet; individual ore pockets range up to 350 feet in length. Elongation is usually at least three times the width and is parallel to paleostream depositional trends measured in and near the ore bodies. Claystone and/or siltstone units nearly always underlie and frequently overlie the host sandstone units. Ore occurs most frequently in trough-type, cross-stratified sandstone which fills scours and channels in the underlying claystone units. Lithofacies maps and mine mapping show that ore bodies are restricted to areas of rapid lateral color change which in general are also areas of rapid change in the ratio of mudstone to sandstone. Most ore bodies are located on the southwest flank of the Chuska syncline within a broad belt which trends nearly north-south across the southeast end of the Lukachukai Mountains. It is suggested that a set of shear joints served as vertical channelways for the distribution of migrating uraniferous ground water. Location of the ore belt is apparently controlled by the intersection of these shear joints and particularly favorable facies of the Salt Wash Member.

Final Report: Airborne Reconnaissance Project Dripping Spring, Quartzite, Gila County, Arizona

Description: Abstract: A low-level airborne radiometric survey of the younger pre-Cambrian Dripping Spring quartzite, undertaken in the mountainous region lying roughly 100 riles east of Phoenix, was completed June 3, 1955. Twenty-seven radioactive anomalies were located. To date seven of these have produced uranium ore, four more will probably become producers, and six others may possibly become producers. Flying was concentrated in the Dripping Spring quartzite, but reconnaissance flights were made over other formations. Private prospecting, both from the air and on the ground, increased considerably when the airborne project started. Eleven of the private discoveries have produced ore, and many others show considerable promise.

The Occurrence of Uranium in the Diamond Head Group, Sierrita Mountains, Pima County, Arizona

Description: Abstract: The Diamond Head droup area is entirely igneous. Tight fractures in alaskite and granite, which have been altered by heiratite and kaolinization contain narrow seams and very locally,pods of sooty uraninite. A greater percentage of the structures in the area strike about east-west and dip steeply to the north, while the radioactive structures have similar strike, they dip steeply to both the north and the south. A drift has been driven on a mineralized structure far enough to ascertain that the general character of the mineralization is very narrow seams. Many such seams exists but are scattered throughout the area.

NURE Aerial Gamma Ray and Magnetic Reconnaissance Survey of Portions of New Mexico, Arizona and Texas, Final Report: Volume 1, Instrumentation and Data Reduction

Description: From abstract: As part of the Department of Energy (DOE) National Uranium Resource Evaluation Program, a rotary-wing high sensitivity radiometric and magnetic survey was flown covering portions of the State of New Mexico, Arizona and Texas. The survey encompassed six 1:250,000 scale quadrangles, Holbrook, El Paso, Las Cruces, Carlsbad, Fort Sumner and Roswell.

Summary Geologic Report on Drilling in Western Prescott and Williams Quadrangles: Mohave, Yavapai, and Yuma Counties, Arizona

Description: From abstract: This drilling project in northwestern Arizona consisted of 18 holes drilled to depths ranging from 1,341 to 5,491 feet (409 to 1,673 meters). The holes were sited to determine the lateral extent of the uranium-bearing, paludal/lacustrine strata of the Anderson Mine in Date Creek basin and to obtain additional data to improve the resource estimates for the Date Creek and Big Sandy basins.
