The Uranium Occurrences in the Martha E Prospect, Lawson-Dumont District, Clear Creek County, Colorado

Description: From introduction: The Martha E prospect, in Spring Gulch about three and one-half miles southwest of Idaho Springs, Colo. (fig. 1), is on a claim, originally called the Daisy Freese, which was first prospected by the Stanley Mines. The occurrence of radioactive minerals in the adit was called to the attention of the U. S. Geological Survey in 1950 by the owners of the claim. The Survey's Trace Elements Section Washington Laboratory identified metatorbernite, autunite, and sooty pitchblende.

Results of Exploration at the Old Leyden Coal Mine, Jefferson County, Colorado

Description: From abstract: Six diamond-core holes totaling 2, 201 feet were drilled by the U. S. Bureau of Mines under contract to the U. S. Atomic Energy Commission at the Old Leyden coal mine, Jefferson County, Colo. The holes were spotted on the basis of geologic mapping by the U. S. Geological survey and were drilled to explore the lateral and downward extent of a uranium-bearing coal and the associated carnotite deposits in the adjacent sandstone. The data obtained from the diamond-core holes helped t… more

Preliminary Report on Exploration in the Spud Patch Area, San Miguel County, Colorado

Description: From introduction: From November 1949 to May 1952, the U. S. Geological Survey explored the Spud Patch area by diamond drilling to find carnotite deposits that would make new mines and to appraise the reserves of the area. Previous work and a brief outline of the general geology of the area have been reported (Bell and Icke, 1950; and Bell, 1952).

Preliminary Report on the Jo Reynolds Area, Lawson-Dumont District, Clear Creek County, Colorado

Description: From abstract: Pitchblende is known to occur in the Jo Reynolds deposit, which was primarily a lead-zinc-silver ore body. The reported production in 1919 of 8 tons of high-grade uranium ore, presumably from the lowest workings of the mine, is still unconfirmed but has a fair degree of credibility.

The Distribution of Uranium-Vanadium Deposits in the Colorado Plateau Relative to Tertiary Intrusive Masses

Description: Introduction: Studies of uranium-vanadium occurrences in the Four Corners region show that, with the exception of the Lukachuai area, all of the major deposits in the Morrison formation are grouped around the various igneous masses which are scattered irregularly throughout the Colorado Plateau. The pattern of deposition varies from mountain group to mountain group and each will be described separately. Maps accompany this report to supplement the descriptions of ore occurrences in the vicinity… more

Results of Diamond Drilling and Geologic Investigation of the Shirley May (Garo) Uranium Deposit, Park County, Colorado

Description: From abstract: The Shirley May (Garo) uranium deposit near Garo, Park County, Colo. , consists of tyuyamunite and carnotite that occur as disseminations and as fracture fillings in three beds of medium- to coarse-grained sandstone. The sandstones are in the Maroon formation of Permian age, This deposit was explored by means of 12 core-drill holes, totalling 2,003 feet.

Reconnaissance for Uranium-Bearing Carbonaceous Rocks in Northwestern Colorado, Southwestern Wyoming, and Adjacent Parts of Utah and Idaho

Description: Abstract: During parts of July, August, and September 1951, a reconnaissance was conducted in parts of Colorado, Wyoming, Utah, and Idaho in search of new deposits of uranium-bearing carbonaceous rocks. One significant uranium occurrence was found, the Fall Creek deposit, Bonneville County, Idaho. Several additional localities were discovered that contain uranium in concentrations many times that normally found in carbonaceous rocks.
