Uranium Exploration Australia is preparing to drill test a recently identified gravity target on its Winjabbie exploration licence in South Australia.

The gravity target is adjacent to the Elizabeth Creek Fault and about 1km from two previous drill holes which intersected significant copper mineralization.

Winjabbie is about 69km south of BHP Billiton's Olympic Dam Mine, 57km west of the Carrapateena prospect and 45km north-northwest of the Mount Gunson copper mine on the highly prospective Stuart Shelf in the Gawler Craton.

Two previous exploration holes drilled in the north-east quadrant of Winjabbie intersected significant copper mineralization.

WJD1 was drilled by Western Mining Corporation in 1980 and intersected a 34 metre oxidized zone of hematite altered rhyolite to lithic and crystal tuff with coarser grained volcanic agglomerate in crystalline basement starting at 827 metres. This was underlain by 154 metres of layered, iron-rich volcanogenic sediments. Assays revealed a 56 metre interval of 0.34% copper.

SAE11 was drilled by Carpentaria Exploration Company in 1990 and intersected thick zones of low grade copper mineralization associated with magnetite and hematite in metasiltstones. The best intersections in 168 metres of mineralization were 94 metres of 0.21% copper from 1005 metres and 42 metres of 0.28% copper from 1123 metres which included 5 metres of 1.1% copper from 1160 metres.

Both holes contained traces of gold and silver as well as low concentrations of uranium. Both were sited primarily on anomalous magnetic signatures.

UXA has recently completed a detailed gravity survey over large areas of the licence and identified a gravity ridge adjacent to these previous drill holes.

The identification of a gravity anomaly adjacent to known magnetic anomalies and interpreted fault structure with previously identified copper mineralization, adds significantly to the applicability of the exploration model being used in the Gawler Craton for iron oxide-copper-gold-uranium mineralization.
