From abstract: Pitchblende, associated with base-metal sulfides, has been found at eight localities in the northern part of Jefferson County, Colo., in shear zones that cut pre-Cambrian metamorphic and igneous rocks, chiefly hornblende gneiss, biotite schist, and granite pegmatite. The pitchblende deposits, with one exception, are in major shear zones that contain vein-like bodies of carbonate-rich breccia. The breccia bodies range from 1 to 5 feet in thickness and are related probably to the Laramide faults, or "breccia reefs" of similar trend, mapped by Lovering and Goddard (1950).

A report discussing an exploration of the san Miguel Bench

From abstract: Experimental simulation of Colorado Plateau type uranium deposits is divided into seven parts. The first three summarize the essential features of geological occurrence for the ores. The last four parts outline the results of experimental investigation arranged according to each geological group of features influencing mode of occurrence.

A report regarding development drilling on the Tiny claim, Gypsum Valley district, San Miguel County, Colorado

Report discussing the geography and ores of the Spud patch area, which acted as a source of carnotite ore from deposits in a sandstone lens.

From abstract: The U. S. Geological Survey made a geophysical investigation on the Gramlich group, Paradox district, Montrose County, Colo., during the period May 26 to July 11, 1952.. Electrical resistivity and self-potential surveys were made to determine the thickness of the upper Salt Wash sandstone and to test electrical prospecting methods in an area of shallow overburden. The investigations were made in conjunction with a diamond-drilling program.

A preliminary report regarding exploration in the Atkinson Mesa Area, Montrose County, Colorado

A report regarding reconnaissance for radioactivity in the Gold Hill Mining Area

From introduction: The purpose of the investigation was to attempt to correlate anomalous radioactivity and mineral distribution in a metal-mining district that shows a distinct areal pattern of distribution of vein types,

A report regarding development drilling on the Upper Group area, Slick Rock District, San Miguel County, Colorado

A report regarding Preliminary reserve statement 33, reserve block 1, South Radium group area, Slick Rock district, San Miguel County, Colorado

The following report covers a reconnaissance resource appraisal in pre-Morrison formations, particularly the Shinarump conglomerate, on the Colorado Plateu and adjoining regions during December of 1951. This report is preliminary in nature and the ideas are presented as a hypothesis to be tested by future work.

The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.
