Bradda Head Lithium Ltd Announces Further Positive Results at Basin

Bradda Head Lithium Ltd (AIM:BHL)(TSXV:BHLI)(OTCQB:BHLIF), the North America-focused lithium development group, is pleased to announce the assay results from the next five drill holes of the Basin East Extension ("BEE") 2023 drill programme

The programme has continued to encounter better-than-expected thicknesses of clay confirming that lithium-bearing clays continue and thicken to the west, northwest and north into the Company's BEE lease with probable extensions into adjoining Basin North ("BN"), and Basin West ("BW") claims. These positive indicators are expected to lead to significant resource expansion for the Company this year.

Key highlights from the recent drilling campaign include:

1. Notable Significant Lithium Intercepts of:

· Notable intervals from the next 5 widely spaced sonic core holes continue to be encouraging and include:

o 81.60m @ 944ppm Li in hole BES23-10, including 19.79m @ 1,325ppm,

o 82.30m @ 906ppm Li in hole BES23-07, including 20.87m @ 1,324ppm and

o 81.98m @ 867ppm Li in hole BES23-06, including 20.73m @ 1,363ppm. See Table 1 for highlighted results.

2. High-grade unit

· The high-grade unit previously found in Basin East ("BE") has similar grades and maintains strong continuity across all of BEE, likely extending into BN and BW.

· This is very positive for any future mining operation as the high-grade unit sits in the upper clay unit which forms the shallowest part of the deposit, essentially cropping out at BE.

· The assays have also identified high levels of molybdenum associated with drill holes BES23-06, 07, 09, and 10 and within the high-grade unit of between 109ppm over 22.56m in hole 06 and 187ppm over 16.44m in hole 10. To put that in context, Freeport's Bagdad copper mine (c.6 miles from Basin) which extracts a healthy molybdenum by-product credit has a molybdenum Proven and Probable Reserve grade of c.200ppm.

3. Resource Expansion:

· The new drill results demonstrate the potential for a substantial expansion of the lithium-bearing clay zone at the Basin Project, significantly increasing the potential resource base.

· The remarkable continuity of the lithium intercepts suggest the presence of extensive lithium mineralisation throughout the project area, indicating the potential for a sizeable lithium deposit.

· Bradda is targeting a +1Mt LCE (lithium carbonate equivalent) Resource this year, which would trigger the next royalty payment of US$2.5m from LRC.

4. Further Exploration Potential:

· The lithium-clay mineralisation remains open to the west, and north, indicating further resource upside, as backed up by the previously reported 1Mt to 6Mt LCE JORC Exploration Target identified by SRK.

· Holes BES23-05, 06, 07, 08, 09 and 10 encountered a thicker and more consistent upper clay thickness on BEE than found at BE. Drilling to date has demonstrated the upper clay gradually thickens to the north, northwest, and to the west towards BW, which is very positive for resource expansion potential into BW, see Figures 1 and 2.

· The total upper clay unit is 78.41m in width on average in BEE. To put that in context the average thickness of the upper clay unit at BE is 34.00m in all the previous 34 holes that intercepted upper clay in the last 3 drill programmes (2018, 2021 and 2022). See Figures 3, 4 and 5.

· Resource estimation work is now underway to produce an updated Mineral Resource Estimate, with SRK incorporating this new drill data.

· The recent drill results on BEE solidify Bradda's belief in a widespread and continuous lithium-rich stratigraphic sequence with potential across BN and BW that the Company believe will lead to significant resource growth and opportunity to become a Tier 1 deposit.

Charles FitzRoy, CEO of Bradda Head Lithium, commented:

"We are extremely excited about the potential for significant expansion of the resource at the Basin Project. The high-grade lithium intercepts encountered in the recent drilling campaign demonstrate the exceptional potential of the project and underscore its importance as a potential strategic lithium asset.

"The 2023 drilling programme at the Basin Project is focussed on further expanding the resource base, delineating additional lithium-rich zones, and is working with SRK to release an updated MRE."

"The Company will soon be kicking off its Phase 3 drill programme at its 23km² San Domingo pegmatite district in Arizona, with the main aim to delineate a Resource and also to build on the promising results of the maiden drill programme which finished earlier this year."

Detailed assay results, including additional intercepts and technical details, will be made available on the Company's website at www.braddaheadlithium.com.

Background
The successful 2022 drilling at BE led to BHL permitting holes on BEE, then mobilising a sonic drill rig to drill up to 25 holes in the Company's BEE State Lease (see press release dated 16 March 2023).

The 2022 sonic drilling at BE tested c.1.4km² of the overall c.46km² property, including Wickieup.

Initial results released on 23 May 2023 at Basin demonstrated the presence across the creek of a complete clay sequence which had not been recorded to date at BE due to varying levels of erosion and basin margin thinning, thus demonstrating the potential for significant resource expansion within the 2.5km² BEE MEP (Mineral Exploration Permit) and southern portion of the 2.6km² BN claim. Bradda's existing compliant Resource is located primarily in the 1.5km² BE state MEP.

The Upper Clay sequence, now confirmed to thicken to the west, northwest, and north 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 current resource.

Holes BES-23-05, 06, and 07 (the first drill holes ever drilled by BHL to the north of the creek, see figure 1), encountered a completely intact upper and lower clay sequence preserved by a basalt layer, signifying the continuation of lithium bearing clays across to BEE from BE and potentially into BN. See Figure 3 and 4 for cross-sections.

Holes 7, 8, and 10 are on the western border of BEE and BW confirm that the upper clay unit continues to thicken to the west.

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.

BHL obtained drill hole permits for 120 sites on the MEP (Mineral Exploration Permit) from the State of Arizona at BEE in 2022, where sonic drilling commenced in late March of this year. The Company also has permission to drill 10 holes on its BN claim (BLM Administered lands). 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 within BEE's northern border.

Bradda Head is in the process of permitting exploratory drilling at its 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 through expansion of its clay resources (see PR dated 22 December 2021). The next payment of US$2.5 million will be paid to Bradda by 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.

QAQC, Sample Preparation

All core samples have been split in half, bagged on site, numbered in depth sequence with certified standards added into the sample stream for quality control. Bags were kept under lock and key prior to their direct shipment to ISO-certified laboratory, SGS, in Burnaby, BC, Canada. Samples were weighed, dried, crushed, then split by rotary convention and placed into 250gram envelopes. The samples were then pulverized to 85% passing 75 microns, then analysed by 4-acid digest, ICP-AES / ICP-MS.
