NTGS databases “Historical Mineral Titles” and “GEMIS” were interrogated to capture past exploration titles overlapping EL33756, and all relevant reports were reviewed. Where relevant, sample sites were digitised and assay results transcribed from older reports. There has been no historical field exploration over the anomalous uranium and Uranium/Thorium ratio area. Most of the historical work conducted within EL33756 was in the northern part of the tenement and focused on the outcropping Hatches Creek Group rocks.

The Elkedra Project area occupies an area of 566km in the Barkly region of the Northern Territory. The region has a semi-arid, tropical climate with average rainfall of 350mm during the summer period from November to March. The exploration field season traditionally occurs from late March to mid-November.

A 400m line spaced airborne magnetics/radiometric survey completed by the NTGS (in 1999) has defined multiple uranium and Uranium/Thorium ratio anomalies which extend continuously over a strike length of approximately 8km.

The surface rocks comprise Cambrian grey black siltstones of the Arthur Creek Formation which are calcareous, carbonaceous, phosphatic and pyritic at depth. Andagera Formation quartz sandstones are also present within the Project area. The Cambrian sediments unconformably overlie early Proterozoic Hatches Creek Group rocks consisting of shallow water sandstones, siltstones and various thicknesses of felsic and mafic volcanics.  The Hatches Creek Group was intruded by the Elkedra granite around 1660 Ma. The Elkedra granite is a medium to coarse grained biotite granite with minor tonalite. There is a ca 100m metamorphic aureole surrounding the granite, which is interpreted to be the source of anomalous uranium and thorium identified in the 1999 magnetic/radiometric survey. It is yet to be determined if the anomalous U/Thorium mineralisation occurs within the Cambrian sediments or within the unconformable interface between the Cambrian and early Proterozoic rocks.
