Manyingee is a typical stacked roll front deposit. The mineralisation occurs at a depth of between 70 and 110m within Lower Cretaceous channel sediments. The 40 to 70m thick Birdrong sandstone hosting the bulk of the uranium overlies 20m of conglomerate and a basal 20 to 40 m thick arkosic unit. The channel sequence is capped by a 10m thick, impervious unit. Several specific uranium roll front systems have been recognised. These were categorized into the Knee, Nose and Conglomerate components and are associated with tabular mineralized sections that have the potential to develop into sub roll fronts.
The previous owners spent A$16 M and defined a resource of 7,860t U3O8 at 0.12% U3O8 . A revised resource model has been developed by Paladin through re-interpretation of the drill data. Paladin has divided the orebody into three distinct rollfront systems (A, B and C) which are controlled by distinct geological environments as illustrated on the below figure which shows the surface projections of the rollfront systems.
The Manyingee Project contains JORC (1999) Code compliant Mineral Resources as shown below:
