The Tanami project comprises of an application in the Tanami region of the Northern Territory (EL 24885 - Pedestal Hill), covering 272 km2. Exploration for stratabound uranium deposits (rollfront and unconformity styles) similar to those in the nearby Ngalia and Amadeus Basins in the Northern Territory is underway. The Tanami is also the largest gold producing region in the Northern Territory, containing the Tanami, Granites and Dead Bullock Soak (Callie Gold Mine) Goldfields.
The Tanami Uranium Project is focussed on uranium hosted by Neo-Proterozoic sediments on the western edge of the Centralian Super Basin. These sediments lie unconformably over crystalline basement rocks of the Granites-Tanami Complex of Archaean to Palaeo-Proterozoic age. The Centralian Super Basin is used to describe the single, more continuous, large basin from which the various sub-basins of Neo-Proterozoic and early Phanerozoic sedimentary rocks, which host numerous significant uranium deposits; the Birrindudu, Ngalia, Amadeus, and Redcliff Pound/Tanami basins, were formed during early Palaeozoic tectonism.
Target lithologies include the Gardiner Sandstone, ascribed to the Birrindudu Group of Upper Carpentarian age (middle-Proterozoic) and the younger Lewis Range Sandstone. The lithologies and geological settings of the Gardiner Sandstone and the Lewis Range Sandstone are virtually identical. Proterozoic granite in the region is a possible source for the target uranium.
