Uranium is found in hundreds of minerals, including uraninite (the most common uranium ore), carnotite, autunite, uranophane, torbernite and coffinite.
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.
