Application of 3D seismic in the delineation of U bearing structures at Ranger 3 Deeps

Abstract

Energy Resources of Australia Ltd (ERA) own and operate the world class Ranger Uranium Mine located in the East Alligator Rivers Region of the Northern Territory. Over the past four years ERA has been undertaking extensive exploration in the area which in 2008 resulted in the discovery of a very significant uranium resource, called Ranger 3 Deeps (R3D), down-dip but separate from the existing Ranger #3 orebody. Evaluation drilling work highlighted the complex structural setting of the mineralisation and detailed pit mapping together with reinterpretation of historical data provided a new perspective on the importance of structural controls to the formation of the Ranger orebodies
