Bradda Head intercepts more significant lithium mineralisation at San Domingo
Bradda Head Lithium Limited (AIM:BHL, OTCQB:BHLIF, TSX-V:BHLI) has returned further significant intercepts of high grade lithium-bearing minerals at multiple locations from the second set of assay results from its maiden diamond core drilling programme at the San Domingo pegmatite district in Arizona.
This is a continuation of the first extensive drilling campaign undertaken at San Domingo since the 1950s, but is the maiden programme under Bradda Head.
Lithium-bearing minerals, namely spodumene and some lepidolite, have been identified in around 60% of the holes completed.
The programme has tested just over 1% of the 23 square kilometres that Bradda holds in Arizona.
Among the highlights were 9.54 metres at 1.85% lithium oxide (Li2O), 3.02 metres at 1.49% Li2O, and 2.90 metres at 3.03% Li2O from the Central Claims, and 3.75 metres at 2.37% Li2O, 0.85 metres at 2.44% Li2O, and 1.10 metres at 0.82% Li2O from the Northern Claims.
This first programme has been focused on shallow drilling and has been designed to help understand the structural controls at San Domingo. These shallow intersections help the company’s geologists interpret what may be present at greater depth, similar to what is seen in comparable systems in Australia.
The potential for deeper feeder systems remains a possibility.
"These results are highly encouraging and set the scene for what we believe has the potential to define a world-class lithium pegmatite district in Arizona, near vital infrastructure and battery end-users within the US and the wider developing North American battery hub,” said Charles FitzRoy, chief executive of Bradda Head Lithium in a statement.
“The US is investing US$135bn in its EV and critical minerals supply chain, all Bradda's assets are located in the US for the US market, these results are therefore extremely supportive of our business model. ESG is front and centre in our approach and we are working to develop these assets with as low a carbon footprint as possible," he added.
He spoke also of “district-scale potential” with “multiple areas showing promising results and high-grade lithium intersections.”
A follow-up drilling programme is planned for the second half of this year. Funds are already in place for this work.
As well as progressing its pegmatite projects, Bradda Head also recently announced commencement of drilling at its Basin project.
