Bradda Head Lithium announces San Domingo drilling results

Global Mining Review,


Bradda Head Lithium Ltd., the North America-focused lithium development company, has announced significant high grade lithium bearing minerals intercepted at multiple locations from the initial set of results from its first diamond core drilling programme at the company’s 23 km2 San Domingo pegmatite district in Arizona. BHL has intersected 31.85 m at 1.60% Li2O in drill hole SD22-024 which includes 3.21 at 3.74% Li2O. This is the first extensive drilling campaign undertaken at San Domingo since the 1950’s and is the maiden programme under BHL.

Highlights include:

  • 31.85 m @ 1.60% Li2O (including 3.90 m @ 2.88% Li2O, and 20.03 m @ 1.97% Li2O (including 7.06 m @ 1.92% Li2O, 3.21 m @ 3.74% Li2O and 3.81 m @ 3.25% Li2O)) in SD-DH22-024.
  • 9.75 m @ 0.78% Li2O (including 5.36 m @ 1.20% Li2O) in SD-DH22-003.
  • 4.27 m @ 1.86% Li2O in SD-DH22-005.
  • 2.44 m @ 1.63% Li2O in SD-DH22-001.

Summary:

  • Bradda Head commenced a 7000 m diamond core drilling programme at its San Domingo lithium pegmatite district in Arizona in 3Q22 as a first pass exploration effort. Once completed, this programme will have tested just over 1% of the 23 km2 that Bradda holds in Arizona.
  • Out of the 7000 m planned, 5700 m (36 holes completed so far) have been drilled with positive results.
  • Partial assays have been received back with Lithium bearing minerals observed in approximately 75% of the holes drilled. This first pass phased drilling programme is expected to be completed by the end of February.
  • Based on the success of Phase 1 at the Northern Claim block, Bradda Head has already commenced a detailed soil survey over its entire 23 km2 land package. Remaining drilling results of the programme will be reported as and when received.
  • The above detailed soil survey programme is scheduled to be completed by early March and along with an ongoing structural mapping programme, will be used to more accurately and efficiently target our Phase 3 drilling programme (due to start 2H23) building on areas covered by Phase 1 and 2 (central claim block), and also to explore the potential at the 99% of our claims at San Domingo that remain untested.
  • It is Important to note that this first programme has been focussed on shallow drilling and with positive intersections of lithium mineralisation recorded at shallow depths (from surface in some holes) in multiple locations across an area in the Northern claim block at San Domingo, where partial assays have now been received. A shallow open cast mining approach therefore seems the route to follow.
  • Phase 2 of this programme at the central claim block has commenced; assays are pending.
  • North American assay laboratories are currently running at capacity and as a consequence turnaround times on assay reporting are excessive, as well as being subject to last minute delays and disruption. Bradda therefore expects all results to be received by the end of 1H23.
  • Assay results for 50% of our 36 completed holes are pending.

Charles FitzRoy, CEO of Bradda Head Lithium, commented:

“These results are 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. The US is investing US$135 billion 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.

“The initial results from this first drill programme at San Domingo highlights a distinct district scale potential. As a result, Bradda is in the process of designing a follow-up drilling programme in 2H23 aimed at testing additional ground within the much wider 23 km2 of lithium pegmatite claims held in Arizona. Funds are already in place for this work, and ongoing exploration work by our geologists suggests that we have only just scratched the surface of what we have at San Domingo with just over 1% of the area tested from this first programme. We intend to keep the market updated on our progress and we look forward to sharing further developments of this exciting project.
