Drilling Progress At Basin Lithium in Clay Project

Bradda Head Lithium Ltd (AIM:BHL, TSX-V:BHLI,), the North America-focused lithium development group, is pleased to provide an update on work at its Basin Project in Arizona. This current drilling program is focused on resource expansion at the Basin North portion of the project. The target is a resource expansion from 1.08 to a minimum of 2.5 million tons (MT) of lithium carbonate equivalent (LCE). Achievement of this would generate a US$ 3.0 million royalty payment from Lithium Royalty Company (LRC).

The first four holes have been logged, sampled, and shipped to the laboratory while drilling of the fifth hole is in progress. Results on all four holes are pending. A further 3 holes are planned.

Highlights:

• The Company has completed four widely spaced holes for a total of 4,330 feet (1,320m) from a planned program of 8,800 feet/2,680 meters (See RNS 12 March, 2024)
• The average Upper Clay thickness, based on visual inspection of the drill core extracted, between the four holes is 85 meters, ranging from 73m to 103m (previous average thickness, excluding Basin East, is 80m)
• Hole 19 has encountered the thickest-ever Upper Clay sequence at 103 meters, potentially demarking the depositional center
• Holes 16 and 18 have encountered Upper Clay shallower than anticipated, yet maintain good thicknesses, hole 17 was abandoned due to poor drilling conditions at a shallow depth and has now been offset and currently being redrilled as hole number 20.
• The four holes (BND24-15, 16, 18, & 19) have encountered between 7 and 37 meters of Lower Clay, a strong indication of continuity from Basin East, located 2.0km to the southeast
• A 7th hole will be added to the south of Basin North, twinning last year's sonic hole BES23-11 (See RNS 21 August, 2023), which cut 88.70m of upper clay averaging 903ppm and 12.51m of high grade at 1,427ppm, but did not penetrate the Lower Clay
• The programme is scheduled to complete in early May with an updated 43-101 Resource to follow once all assays have been received, for which Bradda Head is targeting early June.

Ian Stalker, Executive Chair, commented:

"Drilling the Basin North clays has been an exciting and promising program. Thus far; we're finding excellent clay thicknesses, as expected, and some clay depths have been shallower than anticipated,which is an encouraging result that supports the viability and potential of this project.

​

"We have successfully now completed nearly half of the planned program, bringing Bradda Head increasingly closer to achieving the significant milestone of our target of resource 2.5MT, and unlocking the next royalty payment of US$3m from LRC.

"We look forward to providing further updates in due course."

QAQC

Core samples were cut and sampled at the core shed under the supervision of Joey Wilkins, the Company's COO. The drill core was cut in half and one-half bagged, labelled, and tied-off. Samples were placed in a secure container until the hole was complete then shipped direct to SGS Laboratories in Burnaby, B.C., Canada where they prepped then analysed all samples using 4-acid digest with ICP-AES. Certified standards were inserted into the sample stream to ensure quality control at the laboratory. Mr. Wilkins consents to the inclusion of the technical information in this release and context in which it appears.

About Bradda Head Lithium Ltd.

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 and on the TSX Venture Exchange with a ticker of BHLI.
