San Domingo Pegmatite Project update and newly discovered Ruby Soho Target

 

Bradda Head Lithium Ltd (AIM:BHL), the North America-focused lithium
development group, is pleased to outline results from surface samples
collected at the San Domingo ("SD") pegmatite project in Arizona, USA. Surface
samples at the newly discovered Ruby Soho target showed lithium oxide values
of up to 3.57% with eight samples exceeding or equal to 0.44%. The Ruby Soho
target has not been drill tested previously, permitting is underway, and the
target fits well into our pipeline of pegmatites that have excellent potential
to evolve into near-term resources.

 

Ruby Soho Highlights:

 

·    High value of 3.57% Li(2)O, eight samples exceeding or equal to
0.44%;

·    Spodumene crystals ranging from 2.0cm to 20.0cm, ideal size crystals
for DMS processing;

·    Spodumene identified throughout length of pegmatite;

·  The spodumene exhibits limited surface alteration' - an encouraging
indication lithium mineralization will be consistent with depth;

·    Estimated strike length of pegmatite is 330 meters, pegmatite zone of
540 meters;

·    Additional parallel pegmatites with visible lithium mineralization
(spodumene, lepidolite);

·    Road accessible, within existing NOI (Notice of Intent) drill permit
for simple amending;

·    More field surface sampling and detailed geologic mapping is
immediately planned; and

·    Additional reconnaissance throughout northeast sector of property is
a high priority.

 

Ian Stalker, Executive Chair, commented:

 

"The recent discovery of Ruby Soho highlights the opportunities Bradda Head
continues to uncover as we follow-up on our soil data on the San Domingo
project in central Arizona, USA. Adding another well mineralized pegmatite to
the portfolio, albeit untested by drilling, is highly encouraging for the
Company and furthers our belief that the San Domingo project could contain
economic, mineable, and shallow lithium mineralization across the project.

 

The team also has additional soil anomalies in more remote areas readied for
follow-up that could potentially identify further new and untested drill
targets. Our mission is to pivot towards defining multiple shallow resources
whilst advancing ore body knowledge through additional metallurgical studies.
The relatively simplistic nature of pegmatites and industry proven spodumene
segregation encourages the Company to examine mine permitting and our options
to produce a concentrate; with all metallurgical studies and drill data
expected to form the foundation for a compliant NI43-101 technical report,
anticipated to be produced during 2025.

 

Ruby Soho and the exciting, but un-tested Dragon South and North targets along
with additional near surface opportunities discovered at Midnight Owl, White
Ridge, Morning Star, and Jumbo present outstanding potential to deliver a
resource after the next phase of drilling, projected to proceed in Q1 of 2025,
and meaningfully progress our portfolio towards production."

 

Additional Ruby Soho Target Details

·    Ruby Soho discovered over the summer of 2024 during follow-up on
weakly anomalous lithium soil anomalies and reconnaissance in the northeast
quadrant of the property.

·    The target is 1,500 meters east of Midnight Owl and 350 meters east
of the Lone Giant target.

·    Pegmatite ranges in widths of 1.5 to 6.0 meters width based upon
outcrop and subcrop exposures of the lithium bearing pegmatite.

·    Spodumene crystals fresher than most other parts of the entire
project, ranging in visible sizes from 2.0cm to 20.0cm in length (Figures 1
and 2).

·    Typical LCT signature with elevated to strongly anomalous Rb, Ta, Cs,
and Sn.

·    Additional parallel pegmatites 80 meters to the east contain more
lepidolite than spodumene, but are considered viable targets, have yet to be
sampled.

·    The Ruby Soho pegmatite forms a topographic high, thus, ideal for an
open-pit scenario should the pegmatite be continuous at depth and consistently
mineralized.

·    Out of 14 samples collected along the 540-meter pegmatite trend,
values range from 0.01 to 3.57% Li(2)O with eight samples exceeding 0.44%
Li2O.

·    Elbaite locally found on margins of the pegmatite, mineralogically
similar to schorl.

·    Quartz, feldspar, elbaite/schorl, minor muscovite is the dominant
mineralogy, including spodumene and sparse lepidolite. This mineral assemblage
and zoning are common in productive LCT pegmatites.

Ruby Soho, named for the adjacent "Ruby Wash", was discovered 350 meters east
of the Lone Giant target during a summer reconnaissance campaign and consists
of mostly exposed 330 meters strike length, spodumene bearing pegmatite
(Figures 3 and 4). The eight samples collected along the 330-meter stretch
have a lithium oxide range from 0.01% to 3.57% Li(2)O on a pegmatite that
ranges in widths of 1.5 to 6.0 meters on the surface. Additional spodumene
bearing pegmatites are found within a 540-meter overall trend and could extend
further south to other identified, lithium-bearing pegmatites. This target has
never been drill-tested and has road access to the highest-grade samples. Ruby
Soho is ideally situated on a hilltop and along a topographic high
north-trending ridgeline that would be geotechnically simple for an open-pit
situation, should an economic mineralized pegmatite be identified by
drilling.

 

Ruby Soho has similar LCT geochemical signature to that seen throughout most
of the San Domingo pegmatite complex, running anomalous Rb, Cs, Ta, Be, and
Sn. One sample runs 635ppm Cs, 6,028ppm Be, and 121ppm Ta as an example of the
LCT signature.

 

Further sampling will be conducted on the parallel pegmatites, on the main
Ruby Soho pegmatite, and on surrounding or on strike pegmatites. A review of
access and location for drill sites will be examined and integrated into an
amendment to the existing NOI drilling permit the Company has with the BLM.

 

The Ruby Soho target, similar to other and more advanced targets such as
Midnight Owl, Jumbo, and Morning Star, are found on topographic highs,
symptoms of the resistant nature of many mineralized pegmatites found at San
Domingo and a commonality seen in several of our spodumene-bearing pegmatites.
This critical feature bodes well for resource development and reduces
stripping of waste rock and lower's the timeframe to access mineralized
pegmatites.

 

The Company's current approach to exploration is to convert targets, through
tightly spaced drilling, into near-term mineable resources. While Ruby Soho
has yet to be drill-tested, the Company's experience at San Domingo provides
valuable insight into predicting behavior of the pegmatites at depth and this
target has strong indications of containing evenly spodumene mineralization
down-dip. Bradda are excited to add Ruby Soho into the target portfolio,
similar to Dragon, have become high priority targets the Company anticipate
being ready for drilling in Q1 of 2025.

 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.
