Report issued by the Bureau of Mines over studies conducted on a coal-hydrogenation demonstration plant. The early operations of the demonstration plant are discussed. This report includes tables, illustrations, and photographs.

Abstract: A reconnaissance was made of a large part of the Powder River Basin, Wyoming, during the summer of 1952 to search for uranium deposits in parts of the basin other than the Pumpkin Buttes area. No uranium deposits of economic interest were found, but some rocks of the Tertiary Fort Union formation and the Cretaceous Inyan Kara group were found to be sufficiently uraniferous to justify further search in rocks of these units. Analyses of samples of sandstones, baked shales, and siltstones taken during the reconnaissance show these rocks are considerably more vanadiferous than the average sandstone, or clay and shale.

Report presenting the results of core drilling in Sweetwater county, Wyoming aimed at finding uraniferous coal. Information regarding the locations that were drilled, progress made in drilling, geology of the area, reserves of uraniferous coal, and future plans are included.

A report discussing the results of exploratory core drilling for uranium-bearing coal in the Northern Part of the Red Desert Area, in Sweetwater County, Wyoming.

Summarizing the findings of investigations of radiometrically anomalous areas and discussing recommendations for a diamond drilling program.
