Bradda Head Lithium Ltd
("Bradda Head", "BHL" or the "Company")
New Lithium Discoveries at Bradda Head's San Domingo Project,
Following Completion of Phase 2 Drilling
Bradda Head Lithium Ltd (AIM:BHL, TSX-V:BHLI), the North
America-focused lithium development group, announces final results
from core drilling at the San Domingo Central target area ("Central
Target Area"), Arizona, completed on 2 December 2023. This is the
second of three sets of assays to be released from the Company's
18,950 feet (5,776m) programme, and include very encouraging
results across all the target pegmatites (see PR dated 13 November
2023 for results from the San Domingo North target area).
Results from the San Domingo Central Target Area are highlighted
by the following intervals:
-- 7.28m at 1.27% Li(2) O in hole SD-DH23-069 from 27.43m depth at White Ridge
-- 5.18m of 0.88% Li(2) O in hole SD-DH23-072 at White Ridge
-- 5.06m @ 0.49% Li(2) O in hole SD-DH23-083 at Joker
-- 2.17m @ 0.58% Li(2) O with 92ppm Sn at Jumbo
-- 26.52m @ 0.27% BeO with 4.44m @ 0.40% BeO and 0.02% Li(2) O
in hole SD-DH23-075 at White Ridge
-- Jumbo drill hole SD-DH23-037 (see PR dated 27 March 2023)
encountered 9.54m @ 1.85% Li(2) O from 46.24m, highlighting the
high grades and shallow nature of lithium mineralisation in a hole
that is 400m away to the southwest of hole SD-DH23-069
Summary :
-- Shallow lithium mineralised intercepts were encountered at
the Central Target Area, with 90% of significant intercepts at
<100m depth.
-- The pegmatites at White Ridge host 7.28m of 1.27% Li(2) O,
starting at 27.43m in hole SD-DH23-069. In a parallel pegmatite,
hole SD-DH23-072 intersected 5.18m of 0.88% Li(2) O at 23.77m
(Figure 1 below).
-- Spodumene observed as the dominant lithium mineral with minor amounts of lepidolite.
-- Coarser spodumene (>20cm, and dominant at San Domingo) has
better preservation than finer grained (1-3cm) spodumene, thus,
crystal size is important to overall lithium content and simple
low-cost recovery methods.
-- Elements such as tin, tantalum (Ta(2) O(5) ) and beryllium
(BeO) are found to be highly anomalous in the Central Target Area,
including 0.40% BeO with 118 ppm Ta(2) O(5) over 4.44m in
SD-DH23-075 over 4.44m and within 26.52m at 0.27% BeO
-- Tantalum, tin, beryllium, rubidium, caesium, and niobium were
consistently found to be strongly anomalous within, or peripheral
to, our best lithium intercepts, providing excellent pathfinders
for targeting, interpretation, and guides to this 'Kathleen Valley'
LCT-style of lithium deposit.
-- These, and prior near surface drill hole intercepts in the
Central Target Area, offer potential opportunity for open-pit
development when further drilling proves up mineable resources. The
shallow nature of mineralisation is a compelling argument for
continued exploration.
-- The final news release, to include results from Morning Star,
will follow as soon as data finalisation, compilation, and
interpretation is completed.

Ian Stalker, Executive Chairman, commented:
"These results support our view of a near surface potential
spodumene lithium resource in the Central section of our San
Domingo (SD) property. The results complement and add to the
previous reported results in the same area. We have known spodumene
mineralisation at both Midnight Owl in the north of our SD property
and have now added additional near surface intercepts in the
Central section.
"Our team has been working diligently throughout the year to
interpret the data, and the arrival of the results in December was
something of a Christmas present to ourselves! We are also
confident that they will be a springboard to the next programme. We
are encouraged by this second phase of exploration drilling,
continue to be excited for the future at SD, and look forward to
the next and final set of results from this drilling programme.
"It also needs to be noted that the nature of the mineralisation
encountered to date is simple and shallow; no deep drilling as been
undertaken, although this will be considered at a later stage of
our Company's development. Deeper drilling may indeed reveal less
mobilisation of the lithium due to weathering and, as a result,
broader zones of mineralisation.
"We continue to ensure, via corporate cost reductions and in the
field project work, that we are properly positioned to be ready for
the next wave of lithium demand and subsequent commodity price
increases."

holes, and target areas
This exploration campaign was designed to test for shallow
lithium mineralisation on targets proximal to existing roads and
access, to maximise our ability to test as many pegmatites as
possible from the same or proximal drill platforms, keeping
disturbance to a minimum. Some holes were drilled longitudinally
and others perpendicular to the surface-exposed pegmatites, with
holes designed to test lateral and vertical zoning. Other holes
were step-outs from the previous drilling campaign, such as holes
at Joker and Jumbo, both taking advantage of existing roads or
minimal new roads to lessen impact on the drill permits.
The White Ridge target is a surface expression of parallel,
northeast-southwest to north-south trending pegmatites with several
historic mines excavated on spodumene mineralisation. Drill hole
SD-DH23-069 was drilled longitudinally and intercepted coarse
spodumene crystals at a depth of 27.43m, finding 7.28m @ 1.27%
Li(2) O, with 91ppm Sn, 92 ppm Ta(2) O(5) , and 0.17% BeO. Drill
hole SD-DH23-072 was designed to cross cut the White Ridge mine
(See Figure 3, surface sample with 1.45% Li(2) O), finding 5.18m of
0.88% Li(2) O at a depth of 23.77m and also contains 48ppm Sn.
Drill holes at Joker cross cut a steeply west dipping, and
roughly 15-20m wide, pegmatite with surface expression of 0.25km
strike length. Overall, the drill holes contain an abundance of
fine-grained spodumene although geochemical results were generally
low, interpreted as a lithium depletion of the spodumene, possibly
due to localised hydrothermal activity. The visible spodumene at
Joker reached high volume percentage, between 25% and 50%, but the
depletion of lithium due to localised processes produced low grade
intercepts such as 5.06m of 0.49% Li(2) O, 18.29m of 0.05%, and
10.67m of 0.06% Li(2) O. The pegmatite is open at depth and to the
south, however, further work at Joker will depend upon targeting
less altered zones.
The Jumbo target sits on a hill with limited access and holes
were drilled with intentions to extend mineralisation down dip and
along strike. Hole SD-DH23-081 was a step-out and down-dip hole
looking to extend prior intercepts, such as 9.54m at 1.85% Li(2) O
in hole SD-DH23-037 (See PR dated 27 March 2023). While thinner,
hole SD-DH23-081 encountered 2.17m at 0.58% Li(2) O and 0.55% Li(2)
O over 0.40m at depths of 109.58m and 142.25m, extending
mineralisation to the south. Due to limited access to the west and
south, where greater potential exists, no holes were drilled in
these preferred locations.
The final news release, to include results from Morning Star,
will follow as soon as data finalisation, compilation, and
interpretation is completed. Morning Star is approximately 1km to
the southwest of Jumbo, along the prominent NE-SW corridor of
pegmatites seen on the 10.5km long San Domingo district trend.

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 That part of a Mineral Resource for which
Resource 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.
