From introduction: During 1981 the Bureau of Mines conducted a field investigation of the Bureau of Land Management's Lime Hills, Narrows, and Sand Cove Wilderness Study Areas (WSA's), Mohave County, Arizona as part of a joint effort with the Geological Survey to make a mineral survey of the area. Surface workings and outcrops were examined and samples taken from rock sections that appeared to represent most of the mineralized area. Complete analytical results and sample descriptions are available for public inspection at the Bureau of Mines, Intermountain Field Operations Center, Building 20, Denver Federal Center, Denver, Colo. Part of the area also was examined and sampled in 1979 by L. W. Hamm, Bureau of Mines (Villalobos and Hamm, 1980), during a mineral resource study of the Paiute Primitive Area.

Introduction: This study was made in conjunction with a core drilling program designed to trace ore trends from existing mines eastward under deeper cover. The exploration drilling covered an area of about 1 square mile. The results of previous drilling by the Commission, which covered an additional 10 square miles, have been incorporated in this report.

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.

Abstract: This report consists of four parts, the first three being descriptions of investigations compiled in the period October 1st, 1953 to April 1st, 1954; the fourth part is a summary of progress of the research based on our entire investigations completed prior to April 1st, 1954. The first part comprises a set of preliminary experiments investigating the mineral composition of the sandstones in thin sections, in an attempt to differentiate barren from ore-bearing sandstones. It appears that there are more rock-fragments and particularly more volcanic rock fragments in the ore zone (zone 4, Well C, Bull Canyon). In addition, silica cement appears to be associated with ore and carbonate cement with barren sediments. The second part details the investigation of the mudstones of the Bull Canyon Wells . A mixed layer lattice "illite" and a kaolin mineral are the most prominent in "normal" mudstones. Dye tests suggest there are differences between the clay minerals in the sandstone matrix of the ore zone and barren zone. In addition, the mudstone zones appear to differ in the response to the dye tests. The third part of the report details the bulk density determinations for cores from well B. The results confirm …

From summary: Union Mines' examination of Arizona's pegmatites, lode deposits of the central and southeastern parts of the state, and heavy mineral concentrates from few placer deposits indicates that SOM is practically non-existent in the first two and that minor amounts of monazite and possibly other S-37 minerals are present in the last.

This report presents uranium and other elemental data resulting from the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Dubois NTMS quadrangle in Idaho and Montana. Totals of 1024 water samples and 1600 sediment samples were collected from 1669 locations in the Dubois quadrangle. Water samples were taken at streams, springs, and wells; sediment samples were collected from streams and springs.

From abstract: This report presents the results of the geochemical reconnaissance sampling in the Prescott quadrangle of the National Topographic Map Series (NTMS). Wet and dry sediment samples were collected throughout the 18,770 square kilometer arid-to-semiarid area and water samples at available streams, springs, and wells.

From 1995 sites in the San Juan Mountains area, 1706 water and 1982 sediment samples were collected during June-July 1976 and analyzed for uranium. The area includes the southern third of the Colorado mineral belt which has yielded rich ores of gold, silver, copper, lead, zinc, and molybdenum. The broadly domed mountains are capped by 2500 m of Tertiary volcanics, deeply eroded to expose a Precambrian crystalline core. Adjacent plateaus underlain by Mesozoic sedimentary rocks were included in the reconnaissance. Average value of uranium in water samples from mountains was less than 0.5 parts per billion, from plateaus was 1-2 parts per billion, from Mancos shale areas exceeded 2 parts per billion. Anomalous sediment samples, 40 ppm uranium, came from near Storm King Mountain and upper Vallecito Creek. Other anomalous areas, including the Lake City mining district, were well defined by 4-30 parts per million uranium in sediment and 3-30 parts per billion uranium in water. Anomalous areas not previously reported indicate favorable areas for future exploration.

From abstract: This report presents the results of the geochemical reconnaissance sampling in the Winnemucca 10 x 20 quadrangle of the National Topographic Map Series (NTMS). We collected wet and dry sediment samples throughout the 18,770-km2 arid to semi-arid area and water samples at available streams, springs and wells. We present neutron activation analyses of uranium and trace elements and other measurements made in the field and laboratory in tabular hardcopy and microfiche format. The report includes 5 full-size overlays for use with the Winnemucca NTMS 1:250,000 quadrangle. Water sampling sites, water-sample uranium and thorium concentrations, sediment sampling sites, and sediment-sample total uranium and thorium concentrations are shown on the separate overlays. We present general geological and structural descriptions of the area, and describe the 12 known uranium occurrences.
