Bradda Head Lithium
Ltd
("Bradda
Head" or the "Company")
Metallurgical Scoping Study, San Domingo
Pegmatite Project-Moving Further Along the Potential Production
Pathway, Completion of TSX-V Delisting
Bradda Head Lithium
Ltd (AIM:BHL), the North America-focused lithium
development group, is pleased announce the commencement of a
further metallurgical particle sorting study on the composite
samples collected in 2023 from San Domingo drill core. The purpose
of this new test-work plan in addition the 20 November 2023
reported metallurgical work, is to move Bradda Head closer to
a potential production decision later in 2025.
The study will be supervised and
guided by ABH Engineering Inc.("ABH"), an international leader in
scoping, design, and installation of mineral processing facilities
for the mining industry. ABH, located in Vancouver, BC, Canada,
will oversee the scoping study which will investigate the potential
to increase mill feed grade, reduce product impurities, and reject
baren rock before it enters any milling process. The goal of
testing is to lower cut-off grades and increase potential profit.
Essential elements the Company is
looking to achieve from the scoping study are:
· Increased mill
feed grade, resulting in higher metal production, lower OPEX,
higher mill recoveries, and potentially, increased NPV;
· Early barren rock
rejection to reduce fine tailings, reduce transportation costs,
examine potential for direct shipping or high-grade local ROM
(run-of-mine), reduced toll milling charges, reduce mill and
tailings for lower CAPEX, and lower environmental impacts such as
lower water consumption, reagents, footprint;
· Examine waste
sorting and lower cut-off grades that result in dramatic increase
in reserves and resources, potential to extend mine-life;
and
· It is
also important to note that market quality
Li2O concentrate
(Li2O grades of
6.0% from ¼" crush and 5.5% from 3/8" crush) was produced
previously from a 1.03% Li2O
composite drill hole composite samples using dense
media separation (DMS), a simple low-cost gravity approach (PR Nov
20, 2023).
The study will utilize AI-powered XRT or laser
sorting machines that, in part, will examine potential mechanisms
to sort lithium mineralized rock (spodumene) from gangue rock such
as quartz, feldspar, and muscovite. The systems incorporate dual
energy x-ray transmission or laser sensors to identify valuable
minerals, generating results that could provide data to determine
high-level economic models, obtain grade recovery curves, profit
recovery curves, and lead to quantified economic ore sorting
changes to CAPEX and OPEX.
Ian Stalker,
Executive Chairman, commented:
"We're
excited to embark with this new AI-powered analysis which we
believe will add to the positive gravity concentrate
metallurgical results from 2023. We believe we're on the path
towards developing mineable resources at San Domingo, and these
additional mineral and metallurgical results may well be pivotal
towards unlocking the near-term value on this US based pegmatite
project."
As a reminder of the 20 November 2023 PR,
metallurgical results reported SGS Canada commissioned HLS (heavy
liquid separation) testing on a 1.03% Li2O composite
from Jumbo target drill holes from San Domingo. The test produced
encouraging results:
· The
1.03% Li2O sample produce an 'in spec' lithium oxide
concentrate product with a 6.0% Li2O grade and an
interpolated recovery of contained lithium to the concentrate of
50.3%, at a ¼" size crush size. Tailings rejection was considered
efficient in this scenario with the rejection of 60.6% mass and a
loss of only 2.1% lithium.
·
Alternately, at a crush size of 3/8" (9.5 mm), a concentrate
was produced with a grade of 5.5 % Li2O at a 55.5%
recovery of contained lithium oxide. This is still considered in
spec in the current market.
·
Using the medium-grade sample, the flotation feed, a
combination of middling product from the HLS testing at a crush
size of ¼" and under sized fraction (minus 0.85 mm), recorded an
upgraded value of 1.57% Li2O with Li distribution of
47.0% and a mass distribution of 30.5%.
TSX-V
Delisting
The Company also confirms that its ordinary
shares have been delisted from the TSX-V. The delisting will
not affect Bradda Head's listing on AIM and its ordinary shares
will continue to be listed on AIM under the symbol "BHL".

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.
