Aurora Energy Metals Limited (ASX:1AE) has obtained promising results from a Reverse Circulation (RC) and Diamond Drill (DD) programme completed in December last year at the Aurora Energy Metals Project in south-east Oregon, USA.
The programme had two objectives:
• target the potential for an extension to the north-west of the existing Aurora Uranium Deposit and
• test areas interpreted to host lithium in deeper lakebed sediments.
Sixteen vertical and one angled hole were drilled during the programme, made up of 12 RC and five DD holes, for a total of 3,414m.
“These are good results that confirm our targeting objectives. The uranium results are consistent with the existing resource but show the potential for further extensions,” Managing Director, Greg Cochran, said.
“The lithium results are proof of concept showing widespread lithium in clays at potentially economic grades, very similar to the giant deposits elsewhere in the McDermitt Caldera.”
Lithium results, using a 1000ppm Li cut-off, include:
16.8m at 1,259ppm Li (0.27% Li2O) from 88.4m
19.8m at 1,206ppm Li (0.26% Li2O) from 51.8m
24.4m at 1,138ppm Li (0.25% Li2O) from 39.6m; and
4.6m at 1,334ppm Li (0.29% Li2O) from 82.3m
19.8m at 1,298ppm Li (0.28% Li2O) from 27.4m
9.1m at 1,663ppm Li (0.36% Li2O) from 97.5m
(RC pre-collar samples only – diamond tail assays pending) 4.6m at 1,579ppm Li (0.34% Li2O) from 25.9m; and
4.6m at 1,124ppm Li (0.24% Li2O) from 35.1m
Downhole Geophysical Logging Results
At the conclusion of the drill programme, all accessible holes were geophysically logged to test for uranium and as expected, diamond core hole 22AUDD001, which is closest to historical hole AUD028 that was drilled in 2011 (45.7m at 488ppm U3O8), delivered excellent eU3O8 intercepts.
Additionally, the result from the diamond tail of hole 22AURC00DT, which was drilled outside the current defined mineral resource envelope, also showed intervals similar to those seen in the current resource. All results in the table overleaf are reported using a 100ppm eU3O8 cut-off.
