("Bradda
Head" or the "Company")
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% Li2O, 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% Li2O 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 with scale
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% Li2O 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.
