Final report for EL 26876 Bundey River period ending 8 February 2011

Abstract

EL 26876 was granted to NuPower Resources Ltd on 16 March 2009 for the purpose of uranium exploration. The oldest rocks exposed in the area are early Proterozoic metamorphics of Division 2 and Division 3 of the Aileron Region. These consist of the Perenti Metamorphics and the Ledan Schist. The Mount Swan Granite postdates these units. Overlying the early Proterozoic rocks are three Adelaidean units of the Georgina Basin - the Elyuah, Grant Bluff and Elkera Formations. Some basement rocks in the Aileron Province contain elevated background levels of uranium and thorium and have been explored for gold, base metals, rare earth elements and uranium. Although there are no reported mineral occurrences in the tenements in question, the most significant discovery to date in the region is the Nolans REE-U-Th-P near Aileron. The tenement was taken out over a large coincident radiometric uranium and thorium anomaly which was the focus for NuPower exploration. Exploration has consisted of office based literature research and evaluation of geophysical imagery with, in April 2010, reconnaissance fieldwork. Radiometric anomalies were found to be due to high background of uranium and thorium in a large porphyritic granite body. Concentrations of uranium do not approach economic values such as in Rossing type deposits. Outcrop is generally poor, but enough occurs to fairly reliably suggest that the large radiometric anomaly is almost entirely associated with the granite. The high uranium levels in the granite mean that it would be a good source for secondary deposits. However there is very little sign of calcrete in the area and no obvious indications of sandstone style mineralization. No further work can be recommended on EL 26876.
