Mt Denison
The Mt Denison Project is located within the Lower Proterozoic Arunta Block of the Northern Territory, on the northern margin of the Ngalia Basin. The project has the potential for occurrences of metamorphic and intrusive-related uranium deposits within igneous basement rocks, and sandstone uranium deposits in the overlying sedimentary units.
Primary uranium mineralisation is associated with the metamorphic schists and the pegmatite and granite intrusions. Reconnaissance traverses in mid 1978 indicated several radioactive zones and uranium-rich rocks at Quartz Hill and the Crown anomaly. In the Quartz Hill area uranium mineralisation is associated with apatite bearing schists and with granites at the Crown anomaly, with promising rock chip sample results ranging from 0.002% U3O8 to 0.096% U3O8. The overlying sedimentary units have characteristics favourable for the concentration of uranium by redox processes.
