Reconnaissance Examinations of Copper Uranium Deposits West of the Colorado River

Description: Several relatively small copper-uranium deposits have been found in southwestern Utah along the contact of the Shinarump and Moenkopi formations of Triassic age, at least from the San Rafael Swell area of Emery County, southward through central and eastern Garfield County, southwestward into western Kane County, and westward into the southern part of Washington County.

Primary Sedimentary Trend Indicators as Applied to Ore Finding in the Carrizo Mountains, Arizona and New Mexico

Description: Abstract: Field and laboratory study of primary sedimentary features of the Salt Wash sandstone was undertaken to learn if these structures can be of use in finding hidden deposits of ore and also if they have influenced the localization of either individual ore deposits or larger mineralized districts.

Interim Report on Geologic Investigations in the Monument Valley Area, Arizona

Description: From abstract: The Geological Survey has completed a program of uranium investigation and geologic mapping in the Monument Valley area, Apache and Navajo Counties, Ariz. The program, undertaken on behalf of the 'Atomic Energy Commission, had two principal objectives. The first was to establish prospecting guides for uranium ore deposits. The second objective was to appraise the relative favorableness of formations and areas for the occurrence of uranium deposits in order to select localities that deserve further exploration.

A Lead-Uranium Deposit at the White Oak No. 1 Mine, Santa Cruz County, Arizona

Description: From abstract: A small quantity of uranium ore was shipped from the White Oak No. 1 mine, Pajarito mining district, Santa Cruz County, Ariz., in 1952. The uranium is associated with oxidized lead ore in a shear zone that cuts rhyolite 'porphyry of Tertiary(?) age. The uranium minerals -- kasolite, uranophane, dumontite, autunite, and possibly radioactive pyromorphite -- are concentrated along small, discontinuous fractures, and accordingly the ore bodies are small and widely dispersed.

Structural Analysis of a Mechanized LHD Trench Undercut Caving System

Description: Abstract: This U. S. Bureau of Mines (USBM) report presents results of stress analyses and field observations to investigate the effects of elevated trench drifts on the structural stability of rock mass zones surrounding a production draw drift in a mine utilizing a mechanized load-haul-dump (LHD) trench undercut panel caving system. A two-dimensional boundary-element mine stress model was developed to predict the locations and extent of damaged rock mass zones surrounding draw drifts where adjacent, parallel trench drifts are either elevated or not elevated above the LHD production draw drift level. A Mohr-Coulomb shear-failure criterion was obtained directly from in situ borehole shear test data. Hoek-Brown shear-failure parameter values were computed from borehole-shear and triaxial test data. A procedure is described to estimate these parameters when a rock mass rating (RMR) value and triaxial data on intact samples exist, and no borehole shear test data exist. Results indicate that trench drifts, elevated to the level equal to the height of the LHD production draw drift, would not minimize material damage nor significantly enhance the stability of rib and crown pillar zones surrounding production draw drifts in the mechanized LHD trench undercut caving panel investigated at this mine.

Uranium in the Black Rock District Yavapai County, Arizona

Description: 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.

Radioactivity at the Jim Kane Mine, Mohave County, Arizona

Description: Abstract: About 2,000 tons of low-grade lead ore has been produced from the Jim Kane mine, near Kingman, Mohave County, Ariz. A 3-foot vein of gouge and siderite stringers in pre-Cambrian gneiss contains some lead and, locally, is abnormally radioactive. A sample of the vein contained 0.067 percent uranium. Abnormal radioactivity is restricted to a small part of the vein, and no reserves are calculated.

Mineral Resources of the San Carlos Indian Reservation, Arizona

Description: From abstract: At the request of the Council of the San Carlos Apache Tribe the U. S. Geological Survey entered into a cooperative agreement calling for a brief reconnaissance study to determine, as far as practical, the mineral potential of the San Carlos Indian Reservation. Five months of field work was done during the winter and spring of 1952-53. About 30 percent of the reservation is covered by alluvial deposits of late Tertiary, Pleistocene, and Recent age, and another 60 percent is covered by volcanic rocks of Tertiary and perhaps Pleistocene age. These rocks are younger than the major epochs of metallization in southeastern Arizona. The remainder of the area is underlain by pre-Cambrian and Paleozoic sedimentary rocks, pre-Cambrian granite, and pre-Devonian diabase.
