Uranium Occurrences in Wilson Creek Area, Gila County, Arizona (open access)

Uranium Occurrences in Wilson Creek Area, Gila County, Arizona

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.

The Occurrence of Uranium in the Diamond Head Group, Sierrita Mountains, Pima County, Arizona (open access)

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

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.

Uraniferous Quartzite, Red Bluff Prospect, Gila County, Arizona (open access)

Uraniferous Quartzite, Red Bluff Prospect, Gila County, Arizona

Abstract: Radioactive zones are present in the upper silty part of the pre-Cambrian Dripping Spring quartzite at the Red Bluff prospect, Gila County, Ariz. The prospect is in the SE 1/4 sec. 31, T. 5 N., R. 14 E., at the southern end of the Sierra Ancha area and 12 miles northeast of Roosevelt Dam. Stratigraphic control of the radioactive zones is indicated by the restriction of the zones to two layers, each about 20 feet thick.The zones are spatially associated in part with a diabase dike that occupies a fault, and in part with a thick diabase sill. The main uranium mineral disseminated through the rock in these zones has not been identified definitely, although minor quantities of secondary uranium minerals were observed. The results of scintillometer traverses and radiometric analyses indicate that the deposits probably contain an average of 0.026 percent uranium. Some black streaks and some fractures contain a higher percentage of uranium, but so far as is known the volume of such material is probably too small to affect the overall grade of the deposits.

Preliminary Appraisal of the Carnotite Resources of the Carrizo Mountains Area, San Juan County, New Mexico, and Apache County, Arizona

From introduction: A rapid appraisal of the carnotite resources of the Salt Wash sandstone member of the Morrison formation in the Carrizo Mountains area was undertaken by the U. S. Geological Survey late in 1951 in connection with its current project of geologic mapping of the area. Though brief and preliminary, this report provides a summary of production trends and estimated reserves in the area and indicates as far as possible the total potential of the area as a source of uranium. This information may be helpful in planning new milling facilities or other measures to encourage a higher rate of production.

Preliminary Reconnaissance of the Dripping Spring Quartzite Formation in Gila and Pinal Counties, Arizona (open access)

Preliminary Reconnaissance of the Dripping Spring Quartzite Formation in Gila and Pinal Counties, Arizona

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.

Geology and Ore Deposits of Yazzie Mesa, Apache County, Arizona with Recommendations for Exploration Drilling

Abstract: Yazzie Mesa was examined in May 1951, by the writer, assisted by R. C. Cutter. The mesa shows one main channel deposit and three minor channels. The main channel appears to be a northern extension of a channel deposit being worked by the Vanadium Corporation of America at their Monument No. 2 mine. Two samples taken on the south outcrop of the main channel assayed 0.16% U308 over 4.5 feet and 0.80% U308 over 1 foot. The area is recommended for 10,000 feet of exploration drilling. It is not intended to recommend this footage as a separate contract unit as this report covers only a small part of an area in which drilling will be recommended in forthcoming reports.

Results of Diamond Drilling Mesas 1, 2, 3, and 4, Lukachukai Mountains, Northeastern Arizona (open access)

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

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,
