From purpose and study: The Durango Quadrangle, southwest Colorado (Fig. 1), was evaluated to identify geologic units and to delineate areas that exhibit characteristics favorable for uranium deposits. Geologic environments were evaluated to a depth of 1500 m based on recognition criteria (Mickle and Mathews, eds., 1978) prepared for the National Uranium Resource Evaluation (NURE) program. A favorable environment, as defined for this program, is an environment that could contain at least 100 tons U308 in deposits with an average grade no less than 100 ppm U308 . Environments that did not meet the NURE criteria were categorized as unfavorable. Some of the subsurface and several areas of restricted access were categorized as unevaluated because insufficient data exist for proper evaluation.

From Summary: "Within the gross content of economic exploration techniques developed through case studies of know mineralization, this report of research into the Spokane Mountain uranium deposit integrates the results of numerous field surveys and the application of proven scientific methods with the effects of alternative methods."

A report discussing the Owens Valley Drilling project, with the goal of obtaining subsurface data relevant to the Coso Formation that would permit more reliable estimates of the uranium resources potential of the project and adjacent areas.

This report presents engineering data, statistics, and individual borehole histories of the 28 holes drilled in this project.

This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the 12 holes drilled for this project.

A report discussing a drilling project with the objective of obtaining information to assess the favorability of the Tertiary sedimentary units in the Missoula and Bitterroot Valleys for uranium potential.

From Introduction: "The Montana Quadrangle of the National Topographic Map Series (NTMS), scale 1:250,000, in west-central Colorado was evaluated for geologic environments favorable for uranium deposits."

A bibliographic index of the uranium raw materials reports issued by the Grand Junction Office of the U.S. of the Department of Energy (DOE) or its predecessor, the Energy Research and Development Administration (ERDA), and the U.S Atomic Energy Commission (AEC). The bibliography is in preliminary, unedited form.

"This report is a result of work performed by the Arizona Bureau of Geology and Mineral Technology, through a Bendix FIeld Engineering Corporation Subcontract, as part of the National Uranium Resource Evaluation. NURE is a program of the U.S. Department of Energy's Grand Junction, Colorado, Office to acquire and compile geologic and other information with which to assess the magnitude and distribution of uranium resources and to determine areas favorable for the occurrence of uranium in the United States" "This report describes all known naturally anomalous radioactive occurrences in Arizona."
