World uranium reserves in 2010. Uranium reserves are reserves of recoverable uranium, regardless of isotope, based on a set market price. The list given here is based on Uranium 2020: Resources, Production and Demand, a joint report by the OECD Nuclear Energy Agency and the International Atomic Energy Agency. [1] Figures are given in metric ...
The coastal plain had previously been regarded as highly unfavorable for uranium deposits. [73] The uranium occurs in roll-front type deposits in sandstones of Eocene, Oligocene and Miocene age. [74] The deposits are distributed along about 200 miles (320 km) of coastal plain, from Panna Maria in the north, south into Mexico. Uranium production ...
Smith Ranch and Highland are uranium mining operations located in Wyoming, U.S.A. They are separate permits, operated as a single operation, and have one central processing facility. The Smith Ranch-Highland operation is the largest uranium production facility in the United States. Smith Ranch and Highland are roll-front uranium deposits.
A Navajo discovered uranium in 1942 in Monument Valley on the Navajo Nation in northeast Arizona. The first mine in the district opened in 1948. Uranium and uranium-vanadium minerals occur in fluvial channels of the Shinarump Sandstone member of the Triassic Chinle Formation. Ore deposits are associated with carbonized wood in the sandstone.

[3] [7] [10] The uranium ore minerals include uraninite and coffinite. The age of the uranium formation is assumed to be the same as the caldera tuff, which is approximately 16.1 million years. [7] Other deposits in the caldera contain ores of antimony, cesium, and lithium [11] [12] (potentially, one of the biggest mines in the world). [13]

The site was discovered during uranium prospecting in the 1970s, inspired by the Ambrosia Lake deposit in Canada, with exploration led by the Marline Oil Corporation. Uranium is found within a structural trap, surrounded by biotite gneiss, with staining from hematite overlying the Fork Mountain schist. Hematite staining on the ground surface is ...
The uranium deposits are generally tabular with dimensions ranging up to 1,250 feet (380 m) long, 690 feet (210 m) wide and 165 feet (50 m) thick. Deposits are bounded on at least one side by unmineralized granitic rock. The thickest mineralized zones invariably occur at depressions or flexures in the granitic contact. [6]
