Paddy Well

(U3O8 Limited 100%)

  • Significant zone of copper, gold and uranium mineralisation previously identified.

The Paddy Well project is located in the Gascoyne region of Western Australia, 250 kilometres east of Carnarvon. The project consists of one 28 square kilometre tenement, covering a zone of primary uranium mineralisation in metamorphic rocks of the Lower Proterozoic Mooloo Formation, including calc-silicate gneisses, graphitic and pelitic schists at or near an unconformity with a once extensive sandstone basin (Mt James Formation). Within an area 5 kilometres long and 500 metres wide, numerous radiometric and electromagnetic anomalies have been identified by previous explorers.

Significant uranium mineralisation is associated with magnesian chlorite alteration in a sulphidic graphite schist with assays from drilling up to 0.44% U (4400ppm U) within 4 metres @ 0.12% uranium and 8 metres @ 0.09 % uranium including 1 metre @ 0.37% uranium.

Subsurface uranium mineralisation (>100ppm U) was outlined by drilling over an open-ended zone.   Gold values include 2m @ 0.4 g/t Au, with Cu to 0.15% and Pt + Pd to a maximum of 58 ppb.

Primary mineralisation at the main zone occurs in a vein network 5 metres wide, and consists of uraninite within a 14 metres chlorite halo. Associated elements include Fe, Ca, Mo, Au, Cu, Ni, Co and Bi. Alteration includes quartz replacement, calcite-siderite-ankerite-pyrite, and actinolite. Microprobe analysis detected uraninite grains in chloritic altered schists. The composition of chlorite is similar to alteration related chlorite from the Jabiluka deposit (33.9 million tonnes @ 0.48% U3O8).

Several other prospects with anomalous uranium and alteration have been defined within a 5 kilometre long zone. Detailed magnetic and radiometric survey has been completed over the Paddy Well tenement.  Reverse circulation drilling of the main anomalous area is planned.
