Wabli Creek

(U3O8 Limited 100%)

  • Significant grades of calcrete hosted uranium mineralisation identified through U3O8's drilling programmes
  • Detailed magnetic and radiometric survey completed over project
The Wabli Creek project is located in the Gascoyne province of Western Australia, approximately 300 kilometres east of Carnarvon. Carnotite bearing valley calcrete deposits overly Lower Proterozoic metamorphic and intrusive rocks. Previous exploration in the 1970s and 1980s, involving auger drilling and costeaning at Minindi Creek in the north of the tenement defined an area of carnotite bearing valley calcretes returning assays up to 0.93% U3O8 (9300 ppm U3O8).

At the Wabli Creek prospect similar work defined a small calcrete hosted deposit. Trench samples of calcrete at this locality averaged 0.156% U3O8. The zone of calcrete mineralisation remained open in most directions. Nearby pegmatite outcrops contain pitchblende, with assays up to 0.105% U3O8. Prior to the programmes completed by U3O8 Limited there has been no recorded drilling on the Wabli Creek project area.

Wabli Creek Project

Minindi and Wabli Creek location plan

U3O8 Limited collected a number of rock chip samples from the two separate prospects (Minindi Creek and Wabli Creek). Samples were collected from shallow pits and costeans dug by previous explorers. The area sampled at Minindi Creek extended over an area of approximately 1800 metres x 300 metres.

The Wabli Creek prospect is located a further 10 km upstream along the Gascoyne River and following the same access track. It drains a catchment area hosting multiple uranium occurrences associated with uranium-rich granites, microgranites and pegmatites.

The samples collected from the Wabli Creek prospect focused on a small area incised on the eastern bank of the Wabli Creek that shows economic grades in a terrace deposits draining a nearby granodiorite. Given the nature and thickness of the alluvial cover in adjacent areas, it is anticipated that the overall size of the calcrete significantly exceeds the area tested.

Several drilling programmes have been completed at Minindi Creek as well as the smaller Wabli Creek zone of mineralisation. All holes were drilled vertically by reverse circulation drilling to an average depth of 10 metres approximately.

Some of the better results from the shallow reverse circulation drilling completed to date include:

MCRC 079:  2.36 metres @ 425 ppm eU3O8
MCRC 086:  1.34 metres @ 697 ppm eU3O8
MCRC 092:  2.58 metres @ 877 ppm eU3O8
MCRC 103:  1.76 metres @ 322 ppm eU3O8
MCRC 104:  2.86 metres @ 393 ppm eU3O8
MCRC 105:  1.30 metres @ 450 ppm eU3O8
MCRC 127:  2.54 metres @ 431 ppm eU3O8
MCRC 231:  3.04 metres @ 544 ppm eU3O8
              and  1.02 metres @ 488 ppm eU3O8
MCRC 234:  1.30 metres @ 736 ppm eU3O8





 Contours of uranium intercepts (grade x thickness) at the Minindi Prospect

U308 Limited completed a detailed high-resolution, state-of-the-art aeromagnetic and radiometric survey completed over the Wabli Creek project.

The survey consisted of approximately 2,900 line kilometres of surveying over the entire Wabli Creek Project area.

The acquisition of detailed airborne radiometric and magnetic data is an important step in developing a better understanding of the geology and structure that might control surficial or basement-hosted uranium mineralisation.
