Uranium-Bearing Copper Deposits in the Coyote Mining District, Mora County, New Mexico
Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Permian and Pennsylvanian age south of Coyote, Mora County, New Mexico. Detailed mapping and sampling of these deposits indicate that they occur in carbonaceous zones in shales and arkosic sand-stones. Samples contain as much as 0.067 percent uranium. A yellow radioactive mineral found in the deposits was identified as metatyuyamunite. All of the samples were collected near the surface and are weathered. It is recommended that physical exploration be undertaken to determine the extent and grade of uranium-bearing zones at depth.

Results of Exploration at the Old Leyden Coal Mine, Jefferson County, Colorado
From abstract: Six diamond-core holes totaling 2, 201 feet were drilled by the U. S. Bureau of Mines under contract to the U. S. Atomic Energy Commission at the Old Leyden coal mine, Jefferson County, Colo. The holes were spotted on the basis of geologic mapping by the U. S. Geological survey and were drilled to explore the lateral and downward extent of a uranium-bearing coal and the associated carnotite deposits in the adjacent sandstone. The data obtained from the diamond-core holes helped to explain the geology and structural control of the deposit. The uranium is most abundant in a coal bed that in places has been brecciated by shearing, and then altered to a hard, dense, and silicified rock. The uraniferous coal is in the nearly vertical beds of the Laramie formation of Upper Cretaceous age,

Notes on Eastern Oil Shale Drilling
Purpose: The primary objective of the eastern oil shale drilling was to obtain cores of the Chattanooga shale, from considerable depths and at long distances from its outcrops. Correlation of the cores with outcrop samples showed the effect of weathering on the shale, as well as changes in the stratigraphy. Of secondary interest was acquisition of information on the stratigraphy of the overlying rocks.

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California
From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

Interim Report on Exploration in the Yellow Cat Area, Grand County, Utah
From introduction: This report summarizes the results of diamond-drill and wagon-drill exploration by the U. S. Geological Survey in the Yellow Cat area from October 9, 1951, to May 22, 1952. The Yellow Cat area is about 10 miles southeast of Thompsons, Grand County, Utah. It is accessable by two graded roads which leave U. S. Highway 50 at points 5 miles east of Thompsons and 7 miles west of Cisco, Utah. A sampling plant and purchasing depot, belonging to the United States Vanadium Co., is at Thompsons. The explored ground includes about 8 square miles principally in T. 22 S., R. 22 E., and the northern part of T. 23 S., R. 22 E., Salt Lake meridian (fig. 1). Altitudes in the area range from about 4, 600 feet to 5, 100 feet (datum is assumed but is approximately correct), and the relief is moderate.

Reconnaissance for a Uranothorianite-Bearing Lode in the Vicinity of the Headwaters of the Peace River, Candle Quadrangle, Seward Peninsula, Alaska
From abstract: Reconnaissance in 1947 found uranothorianite and gummite associated with copper sulfides, iron oxides, molybdenite, gold, silver, bismuth, and thorite in placers of a headwater tributary of the Peace River in the eastern part of the Seward Peninsula, Alaska. Brief radiometric reconnaissance early in the summer of 1952 failed to locate the bedrock source of the radioactive minerals at the head of the Peace River, primarily because of the shielding-effect of widespread tundra cover. The samples obtained in 1952 indicate the presence of galena, sphalerite, pyrrhotite, covellite, and fluorite in addition to the minerals reported in the results of the 1947 reconnaissance.

Interim Report on the Radioactive Carbonate-Hematite Veins Near Salmon Bay, Prince of Wales Island, Southeastern Alaska
From abstract: In the vicinity of Salmon Bay near the northeastern end of Prince of Wales Island, southeastern Alaska, samples obtained in 1951 from narrow, steeply dipping, carbonate-hematite veins contain as much as ,O.07 percent equivalent uranium. The average grade of these veins cannot be reliably stated because no systematic sampling has been done. No uranium or thorium minerals have been identified. Several chemical analyses indicate only a few thousandths percent uranium. Most of the radioactivity is apparently caused by thorium, which seems to be in or closely associated with red hematite.

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.
