San Domingo Drilling Results Demonstrate Further Potential for an Extensive Lithium Pegmatite District in Arizona
BRITISH VIRGIN ISLANDS / ACCESSWIRE / February 6, 2023 / Bradda Head Lithium Ltd. (AIM:BHL)(TSXV:BHLI)(OTCQB:BHLIF) ('Bradda Head', 'Bradda', 'BHL' or the 'Company'), the North America-focused lithium development company, announces 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 23km2 San Domingo pegmatite district in Arizona. BHL has intersected 31.85 meters at 1.60% Li2O in drill hole SD22-024 which includes 3.21 meters at 3.74% Li2O. This is the first extensive drilling campaign undertaken at San Domingo since the 1950's and is the maiden program under BHL.
· 31.85m @ 1.60% Li2O (including 3.90m @ 2.88% Li2O, and 20.03m @ 1.97% Li2O (including 7.06m @ 1.92% Li2O, 3.21m @ 3.74% Li2O and 3.81m @ 3.25% Li2O)) in SD-DH22-024
· 9.75m @ 0.78% Li2O (including 5.36m @ 1.20% Li2O) in SD-DH22-003
· 4.27m @ 1.86% Li2O in SD-DH22-005
· 2.44m @ 1.63% Li2O in SD-DH22-001
· Bradda Head commenced a 7,000m diamond core drilling programme at its San Domingo lithium pegmatite district in Arizona in Q3 2022 as a first pass exploration effort. Once completed, this programme (see map below) will have tested just over 1% of the 23km2 that Bradda holds in Arizona.
· Out of the 7,000m planned, 5,700m (36 holes completed so far) have been drilled with positive results, as set out in the table below. Partial assays have been received back with Lithium bearing minerals observed in c.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 (see map) as highlighted by the results noted above, Bradda Head has already commenced a detailed soil survey over its entire 23km2 land package (see PR dated 21 November 2022). 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 H2 2023) building on areas covered by Phase 1 and 2 (Central Claim block), and also to explore the potential at the c.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 (see map and hole 24 cross-section below), where partial assays have now been received. A shallow Open Pit 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, +8 -12 weeks on occasions, as well as being subject to last minute delays and disruption. Bradda therefore expects all results to be received by the end of H1 2023.
· Assay results for c.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$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.
'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 H2 of this year aimed at testing additional ground within the much wider 23km2 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.
'As well as progressing its pegmatite projects, Bradda Head recently announced a 2nd resource update in less than 12 months at its lithium in clay Basin project in Arizona. Further drill programmes are planned to start at the Basin in H1 of this year, which we believe will likely lead to further resource growth at our flagship clay asset. With almost 0.4Mt of LCE already in compliant resources Bradda Head now has the largest publicly announced lithium resource in Arizona and 2023 is expected to be yet another resource growth year for the Company!
'The success of our current programmes at our San Domingo Pegmatites, and also at our Lithium in Clay Basin Project, both located in Arizona, USA, continue to highlight the risk diversification approach followed by Bradda that separates us from many of our peers in the 'Lithium' space.'

San Domingo Phase 1 drill highlights so far:
* All drill holes commenced at surface
The Phase 1 and 2 7,000m diamond core drilling programme was designed to test the thesis that San Domingo is similar in structure to other well-known zoned pegmatites.
Following on from SRK's 3D remote mapping of the Company's whole San Domingo claims, and Bradda's geological fieldwork, the Company decided to increase its claims by 75% to cover 23km2 in 2022, thereby strengthening its position in what Bradda believes has the potential to be a world class lithium district.
In 2022 Bradda completed a soil sampling survey covering c.11% or just under 3km2 of its 23km2 of pegmatite ground in Arizona, yielding highly prospective follow-up drill targets and a 3km trend on the area covered by the soil sampling (see PR dated 21 November2022) with the same elemental signatures that have been seen at known lithium mineralisation locations globally. The programme is now being expanded to cover the remaining 20km2 not extensively soil sampled, with consultants currently in the field collecting samples.
The soil geochemistry suggests that the pegmatite swarm is largely of the LCT (lithium-caesium-tantalum) mineralisation type, the most significant for lithium deposits and what is commonly associated with economic occurrences of lithium and tantalum. LCT-type pegmatites are generally found in the Western Australian pegmatite district, like Tianqi and Albemarle's joint-venture Greenbushes lithium mine.
Bradda is proactively doing everything commercially possible to sample our entire pegmatite district to ensure follow-up drill programmes hit more high-priority targets and to continue to keep intersecting further lithium bearing pegmatites. Bradda has a 10,000m drill programme planned to start in the second half of 2023, using data from the wider soil sampling, current drilling, SRK pegmatite mapping and the upcoming structural mapping programme.
Previous surface sampling at named outcropping pegmatites in the San Domingo claim blocks returned individual sample grade highlights of:
· Midnight Owl: 1.44% Li2O
· Joker: 0.35% Li2O
· White Ridge: 2.49% Li2O
· Lower Jumbo: 1.62% Li2O
· Sunrise: 0.67% Li2O
· North Morning Star: 0.92% Li2O
