Bradda Head Lithium Ltd.

Drill Rig Mobilised to San Domingo Pegmatite District, Arizona

Bradda Head Lithium Ltd. (AIM:BHL, TSXV:BHLI, OTCQB:BHLIF) ("Bradda Head", "Bradda", "BHL" or the "Company"), the North America-focused lithium development company, is pleased to announce drill rig mobilisation for its Phase 3 drill programme at the San Domingo pegmatite district, Arizona. This represents the second large-scale drill programme conducted in less than one year at San Domingo, underscoring the Company's commitment to exploring and unlocking the potential of our 23km² land package within this highly prospective pegmatite district.

Summary:

·    Bradda Head was granted an exploration permit to drill at its Northern claim block in the San Domingo Pegmatite district. A rig has been mobilised and the Company expects to commence drilling this month. See Figure 1 for overview of priority target areas.

·    The Phase 3 drill programme has been rigorously designed, benefiting from a comprehensive array of data and analyses. Bradda's team of geologists conducted an extensive soil geochemistry survey, undertook a thorough structural mapping programme, reviewed previous GPR geophysical data, and carried out additional ground truthing to optimize the locations and potential effectiveness of this exploration campaign.

·    This has resulted in the identification of several new high priority targets which the Company is excited about and anticipates making new discoveries and extending known lithium mineralization from the previous programme.

·    The first two phases of drilling completed in March 2023 yielded promising results, with the best intercept reported as 31.85m at 1.6% Li₂O at the Midnight Owl prospect in the Northern claim block. Phase 3 drilling will aim to extend this known lithium mineralization.

·    San Domingo's strategic location in Arizona places it at the heart of the burgeoning battery supply chain in the Western US. Bradda's 23km² pegmatite district is steeped in a history of lithium mining, with spodumene ore previously mined in the 1940s and 1950s on a small scale from surface at various historic lithium mines within Bradda's claim boundaries.

·    The Company is eager to advance its exploration efforts and work towards delineating the first shallow and potentially open pitable lithium resource at San Domingo.

·    Bradda Head will continue to provide regular updates on the Company's progress at San Domingo, and extends our gratitude to all stakeholders for their support as Bradda work towards unlocking the full potential of this remarkable pegmatite district.

Charles FitzRoy, CEO of Bradda Head Lithium, commented:

"We are thrilled to initiate the Phase 3 drilling programme at San Domingo, building on the successes of our previous phases and leveraging the valuable insights gained from our geologists' groundwork. The aim of this programme is to delineate the first resource at San Domingo, and we are confident in the project's potential to contribute significantly to the developing battery supply chain in the Western US.

"San Domingo's rich history of lithium mining, combined with the positive results from the first two drilling phases, has only increased our enthusiasm and confidence in the project's potential. We remain committed to conducting responsible exploration and maximizing the value of this valuable asset. We have only just scratched the surface of what we have at San Domingo with just over 1% of the area drilled from this first programme. We look forward to sharing further developments of this exciting project.

"The groundwork conducted by our geologists and the comprehensive data analysis have been crucial in designing this Phase 3 drill programme. Our team's efforts are aimed at unlocking the full potential of San Domingo, and we are excited about the possibilities this exploration campaign holds for Bradda Head and its stakeholders.

"As well as progressing its pegmatite projects, Bradda Head recently announced further positive assay results from its lithium in clay Basin project in Arizona. With almost 0.4Mt of LCE already in compliant resources Bradda Head has the largest publicly announced lithium resource in Arizona and the Company expects that resource number to grow significantly this year."

Background

San Domingo's strategic location in Arizona places it at the heart of the burgeoning battery supply chain in the Western US. As the demand for lithium and other battery-related minerals continues to soar, Bradda Head aims to play a pivotal role in meeting the region's requirements while adhering to the highest standards of environmental stewardship.

San Domingo is steeped in a history of lithium mining, with spodumene ore previously mined in the 1940s and 1950s on a small scale from surface at various historic lithium mines within Bradda's claim boundaries. Building on the successful outcomes of the first two phases of drilling, which concluded in March this year and yielded significant lithium mineralisation in approximately 60% of the holes drilled. The Company are eager to advance its exploration efforts and work towards delineating the first shallow and open pit lithium resource at San Domingo.

The Phase 1 and 2 7,000m diamond core drilling programme was designed to test the thesis that San Domingo is similar in structure to other well-known zoned pegmatites. The hundreds of pegmatites at San Domingo are hosted within a 1.6 Ba package of Proterozoic metamorphosed greenstone altered biotite-schists, chlorite-schists, amphibolites, and muscovite-schists. These largely sedimentary host rocks to pegmatites are established as critical to the development of lithium-bearing bodies worldwide.

Out of the 7,000m planned, 7,300m (47 holes completed) was drilled with positive results demonstrating high-grade intersections. This scout drilling programme was completed on 10 March, of which, assays for 47 of the holes have been received.

The Company increased its claims by 75% to cover 23km² in 2022, following on from SRK's 3D remote mapping of the Company's whole San Domingo claims, and Bradda's geological fieldwork, thereby strengthening its position in what Bradda believes has the potential to be a world class lithium district[1] with the potential to deliver a Tier 1 asset.

In 2022 Bradda completed a soil sampling survey covering c.11% or just under 3km² of its 23km² of pegmatite ground in Arizona, yielding highly prospective follow-up drill targets and a 3km trend on the area covered by the soil sampling (see PR dated 21 November2022) with the same elemental signatures that have been seen at known lithium mineralisation locations globally.

The programme was expanded to cover and additional 17km² in early 2023, culminating in a total of 3,885 samples. Samples were collected on 100m spaced lines with sample spacing at 50m, North-South lines.

The soil geochemistry strongly indicates the pegmatite swarms are largely of the LCT (lithium-caesium-tantalum) mineralisation type, the most significant for lithium deposits and what is commonly associated with economic occurrences of lithium and tantalum. LCT-type pegmatites are generally found in the Western Australian pegmatite district, like Tianqi and Albemarle's joint-venture Greenbushes lithium mine. The soil geochemical dataset was thoroughly examined by a geochemist, the result of which point to localization of Li bearing pegmatites along a phosphorous-magnesium geochemical and possible metamorphic boundary. Many of our Li-bearing pegmatites are found along this metamorphic front.

Initial results from the programme were released in February 2023 (see PR dated 06 February 2023) demonstrating the presence of multiple lithium bearing pegmatites. With the best result BHL has intersected 31.85 meters at 1.60% Li₂O in drill hole SD22-024 which includes 3.21 meters at 3.74% Li₂O on the Midnight Owl target.

Spodumene crystals are observed in all six holes drilled on the Jumbo target, with assays for the last hole (SD-DH23-038a) showing multiple intersections of Li₂O grades between 1.01% and 2.44% Li₂O. Previous results from Jumbo include 9.54m @ 1.85% Li₂O in SD-DH23-037 and 4.02m @ 1.27% Li₂O in SD-DH23-035 both at shallow depths.

Bradda continues to expand its knowledge of the property through both innovative and traditional exploration techniques whilst intelligently and proactively doing everything commercially possible to sample the Company's entire pegmatite district to ensure follow-up drill programmes hit more high-priority targets and to continue to keep intersecting further lithium bearing pegmatites.

The Phase 3 drill programme has been rigorously designed, benefiting from a comprehensive array of data and analyses. Bradda's team of geologists conducted an extensive soil geochemistry survey, undertook a thorough structural mapping programme, reviewed previous GPR geophysical data, and carried out additional ground truthing to optimize the locations and potential effectiveness of this exploration campaign.

This has resulted in the identification of several new high priority targets which the Company is excited about in order to make new discoveries or extend known lithium mineralization from the previous programme. A NOI (Notice of Intent) exploration drilling permit was granted by the BLM giving us permission to commence operations in the northern part of the claim block, see Figure 1 for overview of priority target areas.

Bradda Head will continue to provide regular updates on the progress of the Company's exploration efforts at San Domingo, and extend our gratitude to all stakeholders for their support as Bradda work towards unlocking the full potential of this remarkable pegmatite district.
