Phase 2 drilling identifies new lithium-bearing pegmatite zones at San Domingo
BRITISH VIRGIN ISLANDS / ACCESSWIRE / November 20, 2023 / Bradda Head Lithium Ltd (AIM:BHL)(TSX-V:BHLI)(OTCQB:BHLIF), the North America-focused lithium development group, announces initial results from core drilling at San Domingo, Arizona. This is the first set of assays released from the Company's current 6,100m (20,000 ft) programme, which is 65% complete. So far, assays have been received from only 14 holes totalling 993m, with grades of up to 0.83% Li2O over 6.35m and 1.03% Li2O over 3.05m identified.
Summary:
· Preliminary core drilling was conducted at Midnight Owl, Bolt, and Lone Giant in the northern part of San Domingo, amounting to 1,877m in 22 shallow core holes
· This programme is follow-up core drilling to Midnight Owl's previous programme that encountered 31.85m @ 1.60% Li2O in hole SD-DH22-024 at a depth of 26.82m
· Drill hole SD-DH23-049 at the Midnight Owl target discovered a new zone deeper than found in hole 24:
o 6.35m containing 0.83% Li2O at 87.33m depth
o 3.05m of 1.03% Li2O at 98.60m depth
· Results from Midnight Owl also revealed tin and tantalum coinciding with pegmatites and lithium mineralisation
· Drill holes at the new Bolt target, located 800m east of Midnight Owl include:
o 5.27m at 0.51% Li2O within a broader interval of 24.65m carrying 0.24% Li2O in SD-DH23-057
o 5.87m containing 0.48% Li2O contained within 11.8m of 0.32% Li2O in SD-DH23-059
· Core holes at Bolt have detected anomalous levels of tantalum with intervals coincident to the lithium intercepts
Ian Stalker, Executive Chair, commented:
"Our knowledge of this intriguing spodumene-rich pegmatite district grows as we announce our second phase drilling results, which auger well for future development. The initial batch of drill hole geochemistry provides us with an improved understanding of pegmatite characteristics and mineralogical zoning at San Domingo, particularly at the Midnight Owl and Bolt targets.
"The elevated Ta and Sn levels show encouragingly strong comparisons to LCT-type systems, evidence of our robust lithium pegmatite district. Importantly, both Midnight Owl and Bolt targets continue to provide opportunities to expand on the lithium mineralisation, with the goal of defining near surface resources."
See Table 1 below for a summary of results and Figures 1, 2, and 3 for map and cross-sections.
The new Bolt target at San Domingo was found through soil sampling and surface mapping (see announcement dated 15 August 2023). It is important to note that the drill hole geochemical signatures correspond to LCT (lithium-caesium-tantalum) type found in Western Australia at the Kathleen Valley Project. The combination of lithium and tantalum strongly points towards an LCT-type system. Additional holes at Bolt are in the planning stages, although the Company continues to review and interpret the new geochemical results to pinpoint future drilling targets.
Diamond core drilling continues at the Morning Star target with five holes recently completed and several more planned. Both Jumbo and White Ridge targets have undergone a second phase of drilling, with 19 holes drilled over a total of 1,740m. The drilling also includes holes drilled at Joker, where pegmatites contain finer-grained spodumene throughout the extent of the pegmatites. The long intervals of spodumene-bearing pegmatites seen at Jumbo, White Ridge, Joker, and now at Morning Star provide encouragement from the visual lithium mineralisation, although we await laboratory geochemical results.

About Bradda Head Lithium Ltd.
Bradda Head Lithium Ltd. is a North America-focused lithium development group. The Company currently has interests in a variety of projects, the most advanced of which are in Central and Western Arizona: The Basin Project (Basin East Project, and the Basin West Project) and the Wikieup Project.
The Basin East Project has an Indicated Mineral Resource of 17 Mt at an average grade of 940 ppm Li and 3.4% K for a total of 85 kt LCE and an Inferred Mineral Resource of 210 Mt at an average grade of 900 ppm Li and 2.8% K (potassium) for a total of 1.09 Mt LCE. In the rest of the Basin Project SRK has determined an Exploration Target of 250 to 830 Mt of material grading between 750 to 900 ppm Li, which is equivalent to a range of between 1 to 4 Mt contained LCE. The Group intends to continue to develop its three phase one projects in Arizona, whilst endeavouring to unlock value at its other prospective pegmatite and brine assets in Arizona, Nevada, and Pennsylvania. All of Bradda Head's licences are held on a 100% equity basis and are in close proximity to the required infrastructure. Bradda Head is quoted on the AIM of the London Stock Exchange with the ticker of BHL, on the TSX Venture Exchange with a ticker of BHLI, and on the US OTCQB market with a ticker of BHLIF.
Technical Glossary
Kt | Thousand tonnes |
Ppm | Parts per million |
Exploration Target | An estimate of the exploration potential of a mineral deposit in a defined geological setting where the statement or estimate, quoted as a range of tonnes and a range of grade (or quality), relates to mineralisation for which there has been insufficient exploration to estimate a Mineral Resource. |
Inferred Mineral Resource | That part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to an Ore Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. |
Indicated Mineral Resource | That part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes, and is sufficient to assume geological and grade (or quality) continuity between points of observation where data and samples are gathered. |
