Uranium-Bearing Copper Deposits Near Guadalupita, Mora County, New Mexico

Description: Abstract: Dark shale and arkosic sandstone south of Guadalupita, Mora County, New Mexico, contain as much as 4 percent copper and 0. 01 percent uranium on the basis of a few samples recently analyzed. The deposits occur primarily in the dark shale which is about 5 feet thick and dips about 900. Potential reserves of this material are very large. Prospecting and further geologic work will be necessary, however, to evaluate possibilities of these large tonnages. If the deposits can be mined for their copper content, the uranium might be recovered as a byproduct. Detailed mapping and possibly some trenching will be undertaken by the Geological Survey in order further to evaluate the deposits.

Uranium-Bearing Copper Deposits in the Coyote District, Mora County, New Mexico

Description: Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Pennsylvanian and Permian age south of Coyote, Mora County, N. Mex. Mapping and sampling of these deposits indicate that they occur in lenticular carbonaceous zones in shales and arkosic sandstones. Samples from these zones contain as much as 0.067 percent uranium and average 3 percent copper. Metatyuyamunite is disseminated in some of the arkosic sandstone beds, and uraninite was identified in some of the copper sulfide nodules occurring in the shale. In polished section these sulfide nodules were found to be composed principally of chalcocite with some bornite and covellite, as well as pyrite and malachite. Most of the samples were collected near the surface from the weathered zone. The copper and uranium were probably deposited with the sediments and concentrated into zones during compaction and lithification. Carbonaceous material in the Sangre de Cristo formation provided the environment that precipitated uranium and copper from mineral-charged connate waters forced from the clayey sediments.

The Copper and Uranium Deposits of the Coyote District, Mora County, New Mexico

Description: From abstract: The copper and uranium-vanadium deposits of the Coyote district, Mora County, N. Mex., are confined to the lower 2,000 feet of the Sangre de Cristo formation of Pennsylvanian and Permian age. A narrow belt of deposits in steeply dipping or overturned rocks extends for 7 miles along Coyote Creek south of Guadalupita. Earlier studies showed that the copper deposits contained uranium, but both the reserves and the uranium content of the copper-bearing shale are too low to permit the recovery of uranium. However, small, commercial grade uranium deposits have been discovered in sandstone.

Uranium-Bearing Copper Deposits in the Coyote Mining District, Mora County, New Mexico

Description: Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Permian and Pennsylvanian age south of Coyote, Mora County, New Mexico. Detailed mapping and sampling of these deposits indicate that they occur in carbonaceous zones in shales and arkosic sand-stones. Samples contain as much as 0.067 percent uranium. A yellow radioactive mineral found in the deposits was identified as metatyuyamunite. All of the samples were collected near the surface and are weathered. It is recommended that physical exploration be undertaken to determine the extent and grade of uranium-bearing zones at depth.
