San Domingo Pegmatite Project Drill Permit and Met work update

Bradda Head Lithium Ltd (AIM:BHL), the North America-focused lithium development group, is pleased to announce a Notice of Intent ("NOI") drilling permit was approved for the Dragon Target at the San Domingo Project. An additional NOI at San Domingo North  was submitted to the Bureau of Land Management ("BLM"), proposing new drill holes at Ruby Soho and Midnight Owl. Metallurgical work specifically targeting artificial intelligence driven mineral sorting has also commenced on high-grade composite core samples from the Jumbo Target, with results anticipated in Q1 of 2025.

Ian Stalker, Executive Chair, commented:

"The Company is excited to embark on the next phase of exploration drilling at San Domingo in H1 of 2025 and is appreciative of the BLM's quick NOI permit approval on the Dragon target. Bradda has developed an excellent relationship with the BLM in Arizona, as evidenced by this 6^th NOI or amendment approved in the span of just four years. They are an exceptional team at the Hassayampa BLM District office and it is a pleasure working with them. As the Company's geologic team continue to develop new targets, such as Ruby Soho, it is imperative the team works closely with the BLM whilst continuously advancing exploration on the project within the regulations  to progress critical metals essential for the energy transition. 

Initiation of the metallurgical work is also exciting as we look to further unlock the potential at San Domingo by incorporating AI technology on high-grade spodumene mineralized core from the Jumbo Target. This work is designed to identify optimal ore sorting mechanisms through mineral identification during crushing followed by separation of minerals deemed to be sub-ore in grade. Overall, this process is particularly promising for our understanding of the asset and a catalyst for its development.

Several drill bids have been received and more are being solicited from a targeted group of specialized drilling companies. Our objective is to identify smaller reverse circulation equipment that can fit into tighter and smaller drill sites whilst reducing drill pad size and yet drill to the required depths, advantageous for speed and cost-effectiveness.

We are confident we can find the ideal partner and look forward to progressing the metallurgical work in parallel to the exploration drilling at San Domingo, and will provide updates in due course.

Dragon Target

A new NOI permit on the Dragon target at San Domingo was approved by the BLM, allowing up to 37 drill sites and ancillary roads to be built, pending submission of a reclamation bond. The permit allows San Domingo LLC, a wholly owned subsidiary of Bradda Head Lithium Ltd, permission to build and occupy up to 37 drill platforms from where the Company can drill multiple holes. The drill holes will target high grade and outcropping spodumene with samples carrying up to 0.97% Li₂O plus 174 ppm cesium (Cs) over 8.80m from channel samples (See 3 September, 2024 PR) and individual rock chip samples of 7.99% Li₂O (See 3 September, 2024 PR). The Dragon South and North targets have never been drill-tested and contain excellent opportunity to build upon prior drilling campaigns and potentially add resources. The Company is in the process of posting reclamation bonding for final approval to proceed.

Ruby Soho and Midnight Owl Target

A H1 2025 drill program is in the planning stages with drill holes not only at Dragon, with several holes also at Ruby Soho, Midnight Owl, White Ridge, Jumbo, and Morning Star. A new NOI was submitted to the BLM for low-impact exploration at Midnight Owl and Ruby Soho was submitted and is pending approval by the BLM. This new NOI contains proposals for 35 drill sites that will target the newly identified Ruby Soho target, new shallow targets at Midnight Owl, and high-grade mineralization from the Thunder target which was not tested earlier in this year's drill program. The Ruby Soho target, as described in the 26 November, 2024 PR, contains surface samples with up to 3.57% Li₂O on a 330-meter-long pegmatite. The Company plans on drilling along the strike length of the pegmatite with 11 proposed drill sites.

The Company conducted a structural review of the surface and drill hole geology at Midnight Owl, recognizing shallow and undrilled lithium-rich targets that could develop into easily extractable spodumene mineralization. The holes will test mineralization such as 8.40m at 1.17% Li₂O with 623 ppm Cs from channel sampling, as described in the 1 October, 2024 PR. A total of 16 new sites are proposed and will test for shallow mineralization and are part of the recently submitted permit.

Jumbo / White Ridge

A new NOI permit at the Jumbo and White Ridge targets is in preparation and will be submitted once the final details have been compiled. The Company is planning between 10 and 12 drill sites between the two targets. Proposed drill sites at White Ridge will target high grade lithium mineralization identified in channel samples within an open cut mine. Sample results include 5.00 meters at 2.33% Li₂O, 4.10 meters at 2.81% Li₂O, and 5.30m @ 1.25% Li₂O. See PR 8 April, 2024 for detailed results.

Metallurgical Testing

Our consulting group, ABH Engineering, has sent a set of 50 individual ½-inch drill hole core samples to Tomra for X-Ray Transmittance scanning, using their sorting sensor technology at their facility in Germany. This analysis should provide information on particle ore sorting in anticipation of next years mineral resource preparation to illuminate spodumene ore processing. 

Drilling

Drill contractor bids have been solicited from several companies with other additional bids still pending. The program is targeting approximately 10,000 feet or 3,000 meters and upwards of 70 shallow reverse circulation holes. A reverse circulation drill program should produce faster results and projected to cost half of a typical diamond core drilling program.

Technical Glossary

Kt	Thousand tonnes
%	Percent
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.
