Geology & Resources

The Manyingee and Carley Bore deposits are hosted in Lower Cretaceous sediments of the Northern Carnarvon Basin. These sediments are a sequence of fluviatile, deltaic and near-shore facies sediments that were deposited along palaeo drainages which are incised into older stratigraphic units. The sediments are 50-100m thick but thicknesses up to 200m are found in places.

The Birdong Sandstone hosts the majority of the uranium mineralisation and is capped by the Muderong Shale which effectively hydrogeologically confines the Birdrong Sandstone aquifer. There is no surface expression of the mineralisation and the deposit was discovered by drilling a conceptual exploration target.

Mineralisation is considered to be typical of sandstone-hosted roll-front uranium deposits. The mineralisation occurs between 50 and 150m below the surface predominantly within the Birdrong Sandstone. Roll front geometry at Manyingee has been modelled in five sedimentary sequences defined by drilling chip logging and geophysical wireline logging. Discrimination between oxidized and reduced facies is clear due to the visible iron hydroxides in oxidized facies and pyrite in reduced facies. Mapping the interface between oxidized and reduced facies is an essential tool for mineralisation targeting and modelling.

Between 1973 and 1984, approximately 400 holes were drilled by the previous owners to establish the extent and continuity of the sediment-hosted uranium mineralisation. In 2012, Paladin drilled 96 holes for 9,026m of Rotary Mud and 242m of PQ core. The drilling resulted in a revised geological model and, on 14 January 2014, Paladin announced an updated Mineral Resource for the Manyingee Project. The Mineral Resource estimate conforms to the JORC(2012) Code
