Bradda Head Lithium Ltd (AIM:BHL) reported the best results so far from a 2021 drilling programme on its Burro Creek East (BCE) project in Arizona.
Assay results from the first three new holes identified thicker intersections of Upper Clay than anticipated, including a high-grade section of 21.1 metres (m) at 1,506 parts per million (ppm) at hole BCE21-06, where the total Upper Clay zone is 98.6m thick. The thickest section of the Upper Clay zone previously intersected was 68.6m.
The presence of the significantly thicker zone, further south than previously thought, may lead to a larger resource increase in the higher-grade portion of the Upper Clay zone than originally estimated, said the AIM-traded company.
An updated resource, due in the first quarter of 2022, is expected to be “significantly larger” than the current estimate of 185,000 tonnes of lithium carbonate equivalent (LCE), it said.
“These positive drilling results are incredibly encouraging and if we continue to intersect similar depths of the Upper Clay then we may be able to target that zone for a higher-grade resource than what we have currently,” said chief executive Charles FitzRoy.
"The presence of the increased thickness in the Upper Clay zone reinforces our geological interpretation for the Burro Creek lithium deposit and bodes well for the potential at the rest of our Burro Creek claims where we are in the process of permitting for drill programmes in 2022.”
