Geology and Mineralization of the Recently Discovered Rössing South Uranium Deposit, Namibia Available to Purchase
Abstract The Rössing South uranium deposit in Namibia is one of the largest undeveloped uranium deposits in the world and is viewed by many industry participants as the most significant global uranium discovery in the present cycle. Current resources total 121,000 metric tons (t) of uranium oxide, and further exploration is likely to substantially increase the resource inventory. Since its discovery in early 2008, approximately 200,000 m of resource drilling has been completed through January 2010, principally on the Rössing South zones 1 and 2. Further zones of uranium mineralization have been intersected, and these await sufficient drilling to warrant resource estimation. The Rössing South deposit is located approximately 7 km directly south of the Rössing uranium deposit and is separated from it by the Khan River Canyon. The Rössing deposit is the only mining operation currently exploiting the uranium-bearing leucogranites of the Namibian Erongo region uranium province and has been in continuous production since 1976. It produces approximately 7 percent of the annual global supply of uranium oxide. Rössing South shares many geologic characteristics with the Rössing deposit, although it is located on the opposite limb of the regional Kuiseb syncline. The overall in situ grade of the Rössing South uranium mineralization, as it is currently defined, is approximately 480 ppm U 3 O 8 , which is about 25 percent higher than historically mined grades at the Rössing deposit (i.e., ~350-400 ppm U 3 O 8 ) The Rössing South discovery is currently the subject of a feasibility study that has the objective of establishing the viability of a potential globally significant mining operation based on the known uranium resources of zones 1 and 2.
