Summary of Uranium Resources Available in Major Deposits and Prospective Mines Ranger, Olympic Dam and Beverley are the top three mines currently in production in Australia and are described here
Bannerman’s chief executive Len Jubber said these results were directed towards completion of a further mineral resource estimate as part of the ongoing feasibility study work for the Etango Project.
Latest drill hits included assays of 78 metres downhole grading 230 ppm U308; 36m @ 416 ppm, including 6m @ 2,037 ppm; 15m @ 531 ppm; 51m @ 255 ppm; 21m @ 365 ppm and 20m @ 540 ppm U308.
Oshiveli and Onkelo are contiguous with the Anomaly A deposit and form the northern 3 km strike length of the 6 km long Etango Project uranium mineralisation.
5. Active Botswana explorer Impact Minerals (ASX: IPT) said today that its Kekobolo prospect has a geological setting similar to the Letlhakane uranium deposit, owned by another Australian explorer A-Cap Resources Ltd (ASX: ACB).
Lekobolo is 20 km along strike to the south west of the large Letlhakane uranium deposit that covers an area of about 30 sq km. A-Cap Resources has reported its project has an inferred resource of 98 million lb of uranium oxide grading 158 ppm at a cut-off grade of 100 ppm. That deposit is hosted by near-surface calcrete and by Karoo Group sediments.
Takardeit exploration target is 35 – 80M lbs
Has outcropping uranium mineralisation over 3km by 2km area
IND001 – 1.8m @ 1,376ppm eU3O8 from 2.2m depth
IND012 – 1.4m @ 1,691ppm eU3O8 from 13.8m depth
IND014 – 0.4m @ 1,098ppm eU308 from 7.4m depth
Location of IND 001 on top of mesa,
Approximately 150m by 100m with possible 12m ore grade zone through entire outcrop
Several other mesas in the region, all exhibiting high grade mineralisation
2km north of the cross section drill holes
Another mesa to the east of IND001
The whole face is ore grade as measured with an XRF spectrometer, the central high grade core zone is where 13,400ppm was recorded
