Uranium deposits of the Athabasca Basin, Canada and Alligator Rivers region, Australia are located near subhorizontal unconformities between polydeformed/metamorphosed Archean/Paleoproterozoic rocks and overlying essentially undeformed Proterozoic sedimentary rocks. Most deposits are associated with basement-rooted faults; however the location of uranium mineralization to the unconformity is...

The intra-cratonic, Mesoproterozoic Cuddapah Basin in the Dharwar Craton of India hosts several types of uranium deposits in its various stratigraphic levels. Signatures of uranium mineralisation are recorded in the Gulcheru and Vempalle Formations in the lower part and along the unconformity between the basement granite and the overlying sediments of Srisailam / Banganapalle...

INTRODUCTION
Proterozoic unconformity uranium deposits are considered the highest grade deposits in the world. The most recognized deposits occur in the Athabasca basin in Canada [1]. As indicated in the 2016 “Red Book”, Proterozoic unconformity deposits account for about one-third of the world’s uranium resources based upon reasonably assured resources [2]. In 2017, the only two producing...

The Seismic Laboratory (UofS) through industrial partnerships has conducted many seismic reflection experiments within the western and eastern Athabasca Basin. Results to date illustrate that the seismic investigations deliver high-quality primary structural images of the subsurface, with resolution not matched by other geophysical techniques. Correlation of similar seismic signatures from...

INTRODUCTION
The U.S. Geological Survey (USGS) recently completed two uranium mineral resource assessments in the south-central United States (U.S.) as part of a re-evaluation of domestic resources previously considered by the 1980 National Uranium Resource Evaluation program [1]. These new assessments include: (1) in 2015, an assessment of undiscovered roll-front uranium resources in...

The global search for uranium started in earnest at the end of World War 2 and continues through to today. Over the intervening seven decades, a total of $72 billion (in constant 2017 US Dollars) has been spent exploring for uranium. This has led to the discovery of over 1230 deposits (where uranium is the primary metal) containing a total of 11.1 Mt of U. This equates to an average unit...

An ambitious sandstone-hosted uranium mineral prospectivity model covering the entire Australian continent hints at undiscovered mineral potential. Australia was chosen to demonstrate the usefulness of huge-scale multi-criteria analyses due to the relatively large volume of publicly available data covering the entire continent and because it is host to a considerable number of...

Surficial uranium (U) resources exist in the southernmost part British Columbia (Canada). The known U resources in the region (hereafter denoted as SBC) are comprised by four surficial U deposits and 32 small prospects/showings. The prospectivity of the SBC for surficial mineralization has, however, not been entirely evaluated yet. Here, results of spatial analysis of...

Since the publication of the first edition of the IAEA map - World Distribution of Uranium Deposits - more than 2 decades ago, the knowledge of the distribution of different types of uranium deposits has advanced significantly. This has allowed the creation of a more sophisticated and comprehensive database of world uranium deposits (UDEPO). Increased insights, such as a new deposit-type...

Considerable effort has recently been directed towards enhancing and expanding the IAEA database for world uranium deposits, UDEPO. The database is now sufficiently comprehensive to allow use of the data for a wide range of applications, both spatial (such as global map production and mineral potential modelling) and quantitative. The latter application has been commonly been undertaken for a...

Roll-front deposits in Kazakhstan are the source of 40% of the world uranium production [1]. These deposits are characterized by having low production costs due to the use of in-situ recovery (“ISR”) methods for uranium extraction. Consulting companies prepared reports based on international standards (NI 43-101, JORC) and local standards (GKZ system) before 2012. This approach...
