This report presents the results of the mineral survey of the Sierra Ancha Wilderness and Salome Study Area conducted by the U.S. Bureau of Mines. A combined summary report of work done by the U.S. Geological Survey and U.S. Bureau of Mines has been previously published.

This report is on the Hells Gate Roadless Area (3-021), Gila County, Arizona.

This report discusses the results of a mineral survey of the Superstition Wilderness and contiguous RARE II Further Planning Areas, Tonto National Forest, Gila, Maricopa, and Pinal Counties, Arizona.

This report presents the results of a mineral-resource survey of the Mazatzal Wilderness in the Tonto National Forest, Gila, Maricopa, and Yavapai Counties, Arizona.

From objectives and scope: Project objectives were to synthesize available geologic information; to determine favorability criteria; and to describe, appraise, and delineate favorable areas of the Dripping Spring Quattzite.

Interview with J. W. Buck, a highway construction worker, concerning his experiences while employed by the Civilian Conservation Corps during the Great Depression. Buck worked in camps in Globe Arizona; Miami, Arizona; and Veteran, Wyoming.

Script from the WBAP-TV/NBC station in Fort Worth, Texas, relating a news story about movie stars. The filming of a movie stopped while the film's stars, Sarah Miles and Burt Reynolds, testified about the death of David Whiting. Whiting's death was first ruled as an overdose.

Report issued by the U.S. Bureau of Mines discussing copper mining methods and costs in Gila County, Arizona. As stated in the introduction, "this report reviews the underground mining method with emphasis on data and mechanics of block caving as exposed by the open-pit work. It describes the current operating and engineering practice in the open-pit mine with particular emphasis on physical, economic, engineering, and management factors that have affected the choice of mining method and equipment" (p. 1). This report includes maps, tables, illustrations, and photographs.

Report issued by the U.S. Bureau of Mines discussing the mining costs and methods of the Regal asbestos mine in Arizona. Location, history, production, and development details are presented. This report includes tables, maps, illustrations, and photographs.

From purpose and scope: This report is designed to summarize the available information on the geology and ore reserves of the uranium deposits. Detailed geological work has been confined largely to those areas which contain the more promising uranium occurrences with at least 80 percent of such work being concentrated in the Sierra Ancha district.

Supplementary data containing an index map of uranium occurrences in Gila County to accompany a report on U.S. uranium resources in Gila County, Arizona.

Abstract: The discovery and exploration of primary uranium mineralization in the Sierra Anchas of east-central Arizona made possible an analysis of the structural ore controls.

Introduction: A reconnaissance of the Black Brush property was made by geologists of the Atomic Energy Commission in March, 1955. This anomalous area was located by an earlier airborne radiometric survey. the examination consisted of preliminary sampling and surface and underground radiometric traversing.

From abstract: This paper is primarily a progress report on studies designed to accumulate geologic data that will aid in our understanding of the localization and the genesis of uranium deposits in the Dripping Springs quartzite.

From introduction: The exploration project at Christmas was carried on cooperatively by the Geological Survey and U. S. Bureau of Mines. Mr. 0. M. Bishop, Engineer for the Bureau of Mines, examined the property and in his report of June 6, 1942 recommended that six holes be drilled from the 800 level of the mine. The Bureau of Mines began drilling in September 1942, and the Survey investigations began a month later. Since any ore bodies discovered below the 800 level would be inaccessible until a deeper level could be developed, the Bureau and Survey decided to explore from higher levels where resulting benefits could be more quickly realized. Drilling from the upper levels was begun early in 1943.

Abstract: A low-level airborne radiometric survey of the younger pre-Cambrian Dripping Spring quartzite, undertaken in the mountainous region lying roughly 100 riles east of Phoenix, was completed June 3, 1955. Twenty-seven radioactive anomalies were located. To date seven of these have produced uranium ore, four more will probably become producers, and six others may possibly become producers. Flying was concentrated in the Dripping Spring quartzite, but reconnaissance flights were made over other formations. Private prospecting, both from the air and on the ground, increased considerably when the airborne project started. Eleven of the private discoveries have produced ore, and many others show considerable promise.

Report issued by the U.S. Bureau of Mines discussing asbestos mining and production in Arizona. As stated in the summary, "this paper describes most of the chrysotile-asbestos deposits of Arizona. Mining methods are discussed briefly and asbestos-mill flowsheets are incorporated" (p. 1). This report includes tables, maps, illustrations, and photographs.
