(Uraninite) and secondary mierals such as tyuyamunite, carnotite are commonly existed and enriched by water at places in cavities in Vihowa Group (Oligocene Chittarwata, Vihowa, Litra and Chaudhwanan formations) and may be hosted in coal and sandstone bearings formations.
Uranium is found in hundreds of minerals, including uraninite (the most common uranium ore), carnotite, autunite, uranophane, torbernite and coffinite.
Uranium mineralisation at Nowthanna occurs as carnotite over intervals of 0.5 to 6m in width within silicified calcrete layers and carbonate rich sandy clays at or near the water table generally within 10m of surface.
The United States produced carnotite, a mixed uranium/vanadium ore from 1873 which was also used by the Manhattan project together with later imports from Katanga.
The basement mineralisation appears to be associated with the contact zone between granite and gneiss, which microscopic studies show that the granite is alaskinite and the mineralisation is secondary carnotite, while the Red sand mineralisation identified is aeolian red sand.
