Bradda Head Lithium announces results from Basin East Project

Published by , Editor
Global Mining Review,

Bradda Head Lithium Ltd has announced that the final assay results from its 100%-owned Basin East Project (BE) have been received, further emphasising the opportunity for resource growth at this target site.


  • Bradda Head has now received assays from the final four holes from its 10-hole 2021 Basin East (BE) core drilling programme, identifying further thicker intersections of Upper Clay than anticipated, including high-grade sections of 23.6 m at 1495 ppm Li at hole BCE21-09, where the total Upper Clay zone is 81.4 m thick and 18.2 m at 1395 ppm Li at hole BCE21-08.
  • This drilling programme at Basin was completed and announced on 17 November. All core is logged and assayed and no more information is required for SRK to carry out its work on this resource update. The updated resource is due in 1Q22 and is expected to be significantly larger than the current one. SRK, who are undertaking the resource update, are due to visit site w/c 31 January.
  • The further presence of this significantly thicker zone (81.4 m) builds on the data received from hole BCE21-06 where the thickest intersections to date at BE have been seen (98.6 m) and may help lead to a larger resource increase in the higher-grade portion of the Upper Clay zone than originally estimated.
  • Combining these new drill results with the recent geophysical data (RNS 29/10/2021) will enable our geologists to understand with much greater clarity the structure and depth of the clay across our entire Basin Project and will help with the planning and targeting of future drill programmes.
  • The work done to date at Basin East indicates that the Upper Clay zone, which is higher grade than the Lower Clay zone, thickens to the west and north-west, towards Bradda’s other claims at Basin. This may enable Bradda to focus on the Upper Clay zone and delineate a higher-grade resource than previously thought.
  • Previously unknown, but anticipated, lithium mineralisation was also previously discovered (RNS 24/11/2021) in the Lower Clay zone at the twinned holes (BCE21-01, 02, and 03), which again highlights that there is significant potential for an increase in the lithium mineral resource as a consequence. The Lower Clay zone was not tested previously at this location in 2018.
  • These results compare favourably with the current JORC compliant resource of 185 000 t of Lithium Carbonate Equivalent (LCE) in 2018.
  • Drilling is underway at Wikieup, Bradda’s other sedimentary project in Arizona.

Charles FitzRoy, CEO of Bradda Head, commented:

“These further positive drilling results are incredibly encouraging with the presence of similar depths of the Upper Clay meaning that we can target that zone for a higher-grade resource than what we have currently. The results not only provide further confidence to our geological model but, we believe, also add value and the potential to add further resources to our previously-reported numbers of 185 000 t of LCE.

“The continued presence of the increased thickness in the Upper Clay zone reinforces our geological interpretation for the Basin lithium deposit and bodes well for the potential at the rest of our Basin claims where we are in the process of permitting for drill programmes in 2022.

“Basin East is a very small portion of our 47 km2 claims and the results from this programme demonstrate the potential we have. It’s also worth noting that our geophysical programme, has reinforced our geological model and will help us to plan future drill programmes. The funds from the royalty with LRC will enable Bradda to develop an early-stage technical study, and drill at all our 47 km2 of sedimentary claims.

“These are exciting times, not only in terms of the overall lithium market space, but also as our exploration drill programmes, and on-site field work at all three of our lithium targets, continue, with lots of newsflow planned for 2022.”
