Further Resource Expansion Potential Identified at Basin Project in Arizona

Bradda Head Lithium Ltd (AIM:BHL, TSX-V:BHLI, OTCQB:BHLIF), the North America-focused lithium development group, is pleased to announce the initial results from an internal analysis of the first five drill holes of the Basin East Extension ("BEE") 2023 sonic drill programme; confirming that lithium bearing clay continues and thickens to the northwest and north into its BEE lease. Whilst this initial analysis awaits confirmation from the core assays, the apparent and complete stratigraphic section in drill hole BES-23-05 should lead to resource expansion for the Company in Q3 2023.

Highlights:

·    Drilling commenced in March at BEE, and of the 25 holes planned, the first five drill holes have now been completed (see Figure 1) with the initial results endorsing the management's view that the current Resource at Basin will be expanded from this programme.

·    The first four holes (south of the creek) located in BEE and Basin East (BE) (see Figure 1) have shown that the upper clay unit, which prior drill programmes (2018, 2021, and 2022) have shown, is much higher grade that the lower clay unit, thickens to the North and North-west direction into BEE.

·    The fifth hole (the first on the north side of the Creek) confirms this and has a similar upper clay thickness to holes 3 and 4.

·    Hole BES-23-05 (the first drill hole ever drilled by BHL to the north of the creek, see figure 1), encountered what the Company believes is a completely intact upper and lower clay sequence which has been preserved by a basalt layer, signifying the presence of a continuation of lithium bearing clays across to BEE from BE and potentially into Basin North (BN). See Figure 2 and 3 for cross-sections.

·    Bradda's geologists tested the freshly drilled clay core with a LIBS (laser-induced breakdown spectroscopy) handheld device, and lithium was recorded as present in the clay. Bradda has now sent the core to be assayed and will announce the results as soon as received.

·    The upper clay unit is 68m, 77m, and 68m thick in holes BES-23-03, BES-23-04 and BES-23-05 respectively, and to put that in context the average thickness of the upper clay unit is on average 34m in all 34 holes that intercepted upper clay in the previous 3 drill programmes (2018, 2021 and 2022). See Figures 2 and 3.

·    This complete clay sequence seen in BES-23-05 has not been recorded to date in BE due to varying levels of erosion, and demonstrates the potential for resource expansion within the 2.5km² BEE MEP (Mineral Exploration Permit). Bradda's existing compliant Resource is located primarily in the 1.5km² BE state MEP.

·    The Upper Clay zone, now confirmed to thicken to the northwest extent of the previously drilled area towards and into Bradda's BEE claim, could potentially form part of a phased mining operation. This could be mined early in the mine plan as a High-Grade zone sits in the upper part of the deposit.

·    BHL expects to drill up to a further 20 holes at BEE, BE and BN - BEE is adjacent to BE, and BN joins with BEE's northern border (see map in Figure 1). Prior to this programme, c. 1.4km² of the area has been drilled, leading to a Mineral Resource of 371kt of LCE.

·    During this programme the Company will continue to focus on ensuring work is carried out with as little disturbance as possible. Bradda is using sonic drilling, a more environmentally sensitive method as it uses 2/3^rd's less water compared to diamond core drilling.

·    The Company expects to provide the geological results of the remaining drill holes and assays when received and a revised resource estimate will follow after all assays are received.

Charles FitzRoy, CEO of Bradda Head, commented:

"The initial visual analysis of these first five holes is better than expected and is very encouraging as they have further endorsed our view of the geological model and potential of the Basin Project as well as the likelihood of further adding to the existing Resource across Basin.

"The analysis of hole 5 which is the first hole Bradda has ever drilled to the north of the creek, is particularly exciting as it indicates the presence of a completely intact clay sequence which has been persevered by a basalt layer; meaning that the lithium bearing clays at Basin East extend across the creek and open up resource expansion potential. This initial analysis supports our blue-sky model for what we forecast at BEE and on to Basin West!.

"This initial analysis further strengthens our thesis at Basin and we believe our 2023 drill programme will generate material catalysts for the Company and will lead to a further resource upgrade in Q3 of this year.  We look forward to providing further updates as the results from our drilling programme become available."

Background

Following on from the success of the 2022 drilling at Basin East ("BE"), BHL mobilised a sonic drill rig, to drill up to 25 holes, in the Company's Basin Project (see press release dated 16 March 2023).

Following the 2022 sonic drilling at Basin, we have drilled on c.1.4km² of our c.46km² of sedimentary lithium claims in Arizona, comprising the Basin and Wikieup Projects. The 2023 plan at Basin is to increase exploration drilling coverage over as much of our c.46km² of lithium-bearing sediments as possible and, by completing this, BHL anticipates further resource growth in 2023 across this project.

BHL released an updated Mineral Resource Estimate ("MRE") in January this year (see PR dated 16 January 2023), which was the 2^nd MRE that BHL has released in 18 months since Listing on AIM in July 2021.

The Company has obtained MEP drill hole permits for 120 sites at BEE, where sonic drilling  commenced in March of this year. The Company also has permission to drill 10 holes on its BN claim. The difference in the scale of the programmes is that BEE is a state lease, whereas BN is a Bureau of Land Management ("BLM") series of lode and placer claims (see map for all Basin Project claims/leases at https://www.braddaheadltd.com/media). BEE, BE, and BN are contiguous land positions with BEE's northern border.

Bradda Head is in the process of permitting exploratory drilling at its Basin West (BW) and Basin West Extension (BWE) claims through an Exploration Plan of Operations, a procedure with the BLM.

Bradda is targeting to grow its Resource at its Basin project this year with the drill programmes at BEE and BN. Bradda has two royalty payments due from expanding its resources at its clay projects (see PR dated 22 December 2021). The next payment of US$2.5 million is paid on Bradda expanding its resource base to 1Mt LCE (Lithium Carbonate Equivalent), and then the third payment of US$3 million is achieved when Bradda expands its resource base to 2.5Mt LCE. Bradda is working with its geologists to hit these targets as soon as is feasible with the programmes mentioned above and the planned programmes in 2024 at Basin West and Basin West Extension.
