An aqueous solution of uranyl sulfate containing a suspension of subbituminous coal has been heated at 210 C for three days. Examination of the coal at the end of the experiment showed it to contain 31.8 percent uranium recognizable as uraninite by a sharp, strong X-ray diffraction pattern. A similar...

The Last Chance group> Brown Bear and Shady Tree claims in Beaverhead County, Mont., were explored for thorium under a Defense Minerals Exploration Administration Contract in 1951 and 1952. The project was undertaken to explore northwest-trending moderately to steep dipping, thorite-bearing quartz-barite-hematite veins. The veins are wall-rock replacements and fissure fillings...

Anomalous radioactivity and a yellow secondary uranium mineral tentatively identified as carnotite have been found in Tertiary sedimentary rocks about 3 miles northeast of Winston, Mont. The uranium is in tuffs and tuffaceous shales and particularly in beds rich in organic matter. Carnotite(?) was identified from three localities, principally coating...
