Stanley Nabberu

Summary
The Stanley-Nabberu uraniumProject is made up of 12 licences the main licence E69/2294, E69/2295, E69/2296, E69/2297, E69/2298, E69/2299, E69/2265, E69/2266, E69/2267, E69/2268, E69/2269, E69/2270, E69/2300.

The area is under explored and in some cases unexplored and there is gold and base metal opportunities. This project contains highly prospective ground in the vicinity of high anomalous grounds based on aeromagnetic and radiometrics data. It represents a good opportunity for a grassroots discovery.

Geology and Mineralisation
The project area is located in an area occupied by four sedimentary basins and a small inlier of granitoids basement. These granitoids are Archaean to late Paleoproterozoic intrusions and are possibly enriched in uraniumband thorium.

Regional Geophysics
The Tenement area is covered by the Gascoyne 2004 Aeromagnetic and Radiometric Survey completed on behalf of the Government by World Geoscience. The iron formation is shown as a prominent structure with a southeast to northwest direction which passes through tenement E69/2266 on the southeastern portion of the area. The high magnetic response of Stanley Fold Belt is shown by broken lines. north of the Kingston Platform, Bangemall Group.

Further processing may enhance these basin platforms units. The different magnetic responses would suggest that the magnetic could be a valuable mapping tool, either airborne or ground magnetic for specific targets.

Dynasty tenements contains drainage channels ,with known calcrete accumulations as shown by the radiometric image on figure 3. E69/2297, E692267, E69/2294, E69/2300, E69/2295 are within the Bullen Platform of the Bangemall Basin with high radiometric anomalies. E69/2268 and E69/2296 are anomalies in the Kingston Platform of the Bangemall Basin. E69/2266 does not show any anomaly although it is in close proximity of the Malmac Dome Structure and presents good potential for granitiod intrusion Uranium enrichment type deposit AE69/2299 is a tenement that has high radiometric anomaly and may possibly be either a roll front/unconformity
type deposit or calcrete type accumulation and should be investigated closely given that is it in an area in Earaheedy sandstone group in Nabberu Basin with unconformity? with Troy Creek Beds and possible Proterozoic basement rocks.

Target mineralization
Uranium
The main target for mineralisation is paleochannel uranium. This is a style of rollfront uranium deposit where the Uranium in as area is leached and transported in oxidized meteoric waters and deposited in paleochannels in suitable traps where there is either reducing organic material or where the fluid becomes reductive. The main source for uranium is “hot” granite containing elevated Uranium and Thorium, present in these area

There are alluvial drainage channels and calcrete present in the Stanley-Nabberu area . Calcrete is a calcium and magnesium carbonate-rich rock that forms as a chemical precipitate in sediments deposited in drainage channels and playa lakes. Little or no recent exploration for this type of deposit has been identified in the Stanley–Nabberu area. Calcrete hosted uranium deposits in Western Australia are Yeelirrie and Lake way containing 35Mt @ 0.15% U3O8 and 8.52 Mt @ 0.054% U3O8, respectively.

Gold
The gold potential of the area through possible inliers of Archaean associated with the Archaean intrusive in the area. There is also potential for orogenic gold deposits within the sediments and metamorphics of the area.

Base Metals
There is potential in the area for sediment hosted Zn-Pb-Ag mineralisation. Parts of the Bangemal and Nabberu Basin have developed basins of sufficient thickness to produce brines that could form sizable deposits. Targeting of areas with thick sedimentary packages with changes in formation thickness across basin forming faults. Examination of potential for Cu-Au deposits of the recently discovered Degrussa type will also be examined. Ni-Cu_PGE deposits may be associated with ultramafics in the area also.

Iron Ore
The Frere formation is a BIF which can contain 50-60% Fe in enriched zones. The magnetics show the strong continuation of this formation through tenement E69/2266. This would be the most prospective zone for Iron ore within the tenements. Potential for other BIF within the Frere Formation elsewhere should also be examined.
