Report issued by the Bureau of Mines over studies conducted on the characteristics of reservoir-oil sampled from San Juan County, Utah. The properties of each sample collected are presented. This report includes tables, graphs, maps, and illustrations.

Report issued by the U.S. Bureau of Mines discussing the costs and methods of uranium mining in San Juan County, Utah. History, geology, and production of the uranium mines are presented. This report includes tables, maps, illustrations, and photographs.

Report issued by the U.S. Bureau of Mines discussing uranium mining methods. As stated in the introduction, "the Federal Bureau of Mines is publishing a series of studies on the methods and costs of mining uranium on the Colorado Plateau. This report describes the long-wall mining methods and techniques used at the Radon mine, Big Indian district, San Juan County, Utah" (p. 1). This report includes maps, tables, illustrations, photographs.

Abstract: The uranium occurrences near Goodsprings, Clark Co., Nevada, are divided into two distinct types which differ from each other in geographic distribution, localization of mineralization, mineralogy and origin. None of the known deposits is of present commercial significance and therefore this study emphasizes the genetic rather than the economic aspects.

Introduction: Under a contract between the United States Atomic Energy Commission and the University of Utah the writer has been investigating the sedimentary relations of the uranium deposits of the Salt Wash sandstone in the Colorado Plateau.

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: On March 7, 1953, after approximately three and one-half months, investigational drilling in the North Point No. 6 and Horn channels was completed.

From introduction: This report contains the results of a detailed geological and uranium deposits study made of the Monument Valley.

From abstract: The Happy Jack mine is in the White Canyon area, San Juan County, Utah. Production is from high-grade uranium deposits in the Shinarump conglomerate of Triassic age. The Shinarump strata range from 161/2 to 40 feet in thickness and the lower part of these beds fills an eastward-trending channel that is more than 750 feet wide and 10 feet deep.

From introduction: Field work, begun in the field season of 1951, was continued by the U. S. Geological Survey in the White Canyon area, San Juan County, Utah, from May 1 to October 28, 1952, The objectives of this work were to study the habits and character of uranium deposits in the area, to determine control and guides to ore and suitable areas for physical exploration, and to map and study the ore-bearing and adjacent strata to determine the regional geologic controls and habits of the uranium deposits, The White Canyon project is part of a regional mapping program on the Colorado Plateau being conducted by the Geological Survey on behalf of the U. S. Atomic Energy Commission.

From abstract: The results of diamond-drill exploration for the Shinarump member of the Chinle formation in Clay Gulch, San Juan County, Utah, indicate that between Clay Gulch and exposures along Red House Cliffs, about 2 miles east, a dominantly continuous blanket of the Shinarump member wedges out northeast of a line trending N. 150 W.

From abstract: These results demonstrate that the self-potential method is not satisfactory for locating and delineating sulfide-bearing uranium ore bodies under conditions similar to those in the Happy Jack area.

From abstract: The purpose of this preliminary electrical resistivity investigation of Holiday Mesa, Monument Valley region, San Juan County, Utah, was to determine the feasibility of a detailed survey to delineate channels cut into the Moenkopi formation and filled with sediments of Shinarump conglomerate. These structures are in many places related to the localization of uranium ore.
