GARDNER RANGE & MT MANSBRIDGE PROJECT

Uranium-Gold

Prospective for unconformity related uranium deposits such as those of the Athabasca Basin in Canada which has produced a significant proportion of the world's uranium output. The prospective ground is surrounded to the north by Cameco, the large, Canadian uranium miner.
An unconformity exists between the early Proterozoic Killi Killi Beds, which are shallow marine deposits and the Mid-Proterozoic Gardner Formation, which is composed of course fluvial sandstones. The Gardner Formation is the lowermost unit of the Birrindudu Group.
Exploration by BHP Minerals and Canadian Energy Resources in the early 1980's located uranium and gold occurrences adjacent to the ranges.
Past exploration involved radiometric surveys, electro-magnetic, mapping and pitting.
A series of highly anomalous and strongly kaolinized zones were deleniated over a length of 300 metres, within a broader biogeochemical halo (600 metres in length and 200 metres wide). Eight pits were anomalous of which five returned between 430 ppm and 980 ppm uranium.
The region contains a sixty kilometre fault system which has never been explored.
Modern day geochemical and airborne geophysical methods will be employed to assess these areas.

The Gardner Range project tenement, which includes the Mt Mansbridge uranium prospect, has been granted. The proposed exploration activities are intended to investigate the nature of base metal mineralisation associated with the unconformity between the Killi Killi Beds and the Mid-Proterozoic Gardiner Sandstone. This programme will include a programme of loam sampling of targets over the defined region, stream sediment sampling of the sparce drainage in the region and drilling to define the nature of targets.

A joint airborne geophysical survey is being undertaken in conjunction with Cameco over the joint tenement interests. A TEMPEST (EM) survey was completed by Fugro and a magnetics and radiometrics survey is currently being undertaken by UTS. This data will assist in the understanding of the region and in developing drill targets.
