Final Cobra Run - Army RC Transformation Cheyenne Wyoming

Report issued by the Bureau of Mines over studies conducted on the pilot plant in Laramie County, Wyoming. As stated in the introduction, "the purpose of this report is to record information derived from recent experimental work that had as its objective the development and demonstration of one method of producing sponge iron" (p. 2). This report includes tables, illustrations, and photographs.

Abstract: An airborne radiometric survey of parts of the east flank of the Big Horn Mountains was begun on June 23, and completed on August 27, 1952. An area of approximately 250 square miles was covered, and only two anomalies were found in the entire area. Flight lines were arranged in accordance with the geology of the area, particular attention being given to formations the stratigraphic equivalents of which are known to be uranium bearing in other areas. Two additional zones of radioactivity were found by ground investigation, but assays from both the ground and the airborne discoveries showed no economic uranium deposits.

Introduction: This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the nine holes drilled in the Great Divide Basin project during the 1981 drilling program. General information is presented regarding specific problems including weather and logistics. A separate geologic report is being prepared and will be available through the Bendix Field Engineering Corporation Technical Library in the near future.

From Introduction: "The Richfield 1º x 2º Quadrangle (Fig. 1), Utah, was evaluated to identify and delineate areas and geologic areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. A favorable area or environment, according to the specifications used in this study, is one that is known or is likely to have uranium deposits containing a minimum of 100 tons of U3O8 with an average grade of not less than 100 ppm U3O8."

From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."

From Purpose and Scope of Study: "The Torrington 1ºx2º Quadrangle in southeastern Wyoming and a small area of westernmost Nebraska was evaluated to determine areas favorable for the occurrence of uranium deposits. Geologic environments (areally or stratigraphically restricted parts of a geologic unit) were placed in categories of favorable, unfavorable, or unevaluated."

From Introduction: "The Casper NTMS 1º x 2º Quadrangle, Wyoming (Fig. 1), was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. Formation and environments were evaluated for uranium favorability to a depth of 1500 m by surface and subsurface studies."
