Report issued by the U.S. Bureau of Mines discussing the mining practices and expenses of the United Verde open-pit mine west of Jerome, Arizona. As stated in the introduction, "the purpose of this paper is to present the methods used in developing and operating the mine, and to discuss the problems encountered" (p. 1). This report includes tables, maps, and illustrations.

Report issued by the U.S. Bureau of Mines discussing mining methods in Arizona mines. As stated in the introduction, "this paper describes mining operations at the Iron King mine of the Shattuck-Denn Mining Corp. in Yavapai County, Ariz." (p. 2). This report includes tables, maps, illustrations, and photographs.

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.

From purpose and scope: and primary objective was to determine the extent and grade of ore present and the future potential of the district. The second and broader objective was to learn the relationship of ore to stratigraphy and structure, in order to outline similar areas favorable for prospecting.

From abstract: A team consisting of R. A. Lindblom, S. A. Mayer, R. G. Young, W. L. Chenoweth, R. F. Droullard, and I. T. Fisk made a reexamination of the Anderson mine (Uranium Aire) of Interstate Oil and Development located near Wickenberg in Yavapai County, Arizona. The field examination was made from August 22, 1958 to September 2, 1958. This team was formed to resolve differences between company and AEC ore reserve estimates. A cooperative effort in which the company supplied labor, limited additional drilling and both parties were in attendance during the sampling resulted in the collection of additional data. Special attention was given to assessing the in-hole assaying with radiometric equipment by IOD and AEC, evaluation of tonnage factors, moisture content, continuity of ore, and current mapping of stripped and mined areas.

Report issued by the U.S. Bureau of Mines discussing the open-pit copper mining of Yavapai County, Arizona. As stated in the summary, "mining methods, including breaking ground, primary drilling and blasting, secondary drilling and blasting, loading, transportation, engineering, and operating control, are described" (p. 1). This report includes tables, maps, illustrations, and photographs.

From summary: The objective of the project was to obtain subsurface data that would permit a more accurate estimate to be made of the uranium potential in the Tertiary basins within the project area.
