106m Continuous Pegmatite Interval Reported
Broad Intervals of Visible Spodumene Observed in Multiple Drill Holes Outside
of the Current Mineral Resource Estimate
Longest continuous pegmatite interval reported
from the ongoing, recently-enhanced 2023 drilling programme
Atlantic Lithium Limited (AIM: ALL, ASX: A11, OTCQX: ALLIF, "Atlantic Lithium"
or the "Company"), the African-focused lithium exploration and development
company targeting to deliver Ghana's first lithium mine, is pleased to
announce that multiple broad intervals of visible spodumene have been observed
in drilling outside of the current Mineral Resource Estimate(1) ("Resource" or
"MRE") at the Company's flagship Ewoyaa Lithium Project ("Ewoyaa" or the
"Project") in Ghana, West Africa.
Highlights
- Multiple broad intervals of visible spodumene reported in drilling
outside of the current MRE(1), significantly increasing the potential for a
resource upgrade.
- Longest reported continuous pegmatite interval in the 2023 drilling
programme to date of 106m in hole GRC1020 from 6m at the Dog-Leg extension
target on the northern tip of the Ewoyaa Main deposit.
- Visible coarse-grained spodumene fragment intervals reported at
shallow depths in holes:
· GRC1017: 51m interval of 25-30% visual estimated spodumene modal
abundance from 83m
· GRC1020: 74m interval of 20-25% visual estimated spodumene modal
abundance from 39m and a 41m interval of 20-25% visual estimated spodumene
modal abundance from 137m
· GRC1021: 24m interval of 15-25% visual estimated spodumene modal
abundance from 93m
- Coarse-grained, P1-type spodumene pegmatite is preferred for the
Dense Media Separation ("DMS") process flowsheet considered in the Definitive
Feasibility Study for the Project (refer announcement of 29 June 2023).
- Resource drilling ongoing; completion of the enhanced 26,500m
planned programme (refer announcement of 7 November 2023) targeted for Q2
2024.
NOTE: Visual estimates of mineral abundance should never be considered a proxy
or substitute for laboratory analyses where concentrations or grades are the
factor of principal economic interest. Visual estimates also potentially
provide no information regarding impurities or deleterious physical properties
relevant to valuations.
Commenting, Neil Herbert, Executive Chairman of Atlantic Lithium, said:
"In line with our aim of delivering an increased resource at the Ewoyaa
Lithium Project, we are very pleased to report broad intervals of visible,
coarse-grained spodumene in multiple drill holes near surface and outside of
the current MRE footprint. These intervals further improve our confidence in
delivering an updated MRE upon completion of the current drilling programme in
Q2 2024.
"We are excited to have intersected our longest pegmatite interval in the 2023
drilling programme to date. Located outside of the current Resource footprint
and occurring only 6m from surface, the interval includes highlight
intersections of visible coarse-grained spodumene over 74m from a depth of 39m
and over 41m from a depth of 137m, respectively.
"The coarse-grained, P1-type nature of the spodumene fragments observed in
Reverse Circulation drilling chips is very encouraging as it performs
favourably in DMS-only processing, as planned at the Ewoyaa Lithium Processing
Plant, with good recoveries.
"We look forward to providing further updates from the ongoing drilling
programme in due course."

Broad Intervals of Visible Spodumene
Drilling outside of the current MRE(1) has intersected multiple intervals of
pegmatite, including multiple broad intervals of coarse-grained visible
spodumene at the Dog Leg prospect extension (refer Figure 1 and Figure 3). The
drilling forms part of the ongoing resource infill and extensional programme,
which was recently increased from 18,500m to 26,500m of planned drilling, due
for completion in Q2 2024 (refer announcement of 7 November 2023).
Highlight logged pegmatite intervals with visible estimates of spodumene modal
abundance in RC drill chips are summarised in Table 1 below, with all logged
intervals and collar details reported in Table 2 and Table 3.

The drilling reported herewith is located at the Dog-Leg extension target on
the northern tip of the Ewoyaa Main deposit, at the confluence of the Ewoyaa
Main trend and the Ewoyaa North-East trend (refer Figure 2 and Figure 6).
A similar structural setting occurs further north at the Ewoyaa Main Sill
deposit where the north-south trending Ewoyaa Main trend intersects the
east-west trending Grasscutter trend and is significant as it results in flat
lying sill geometry mineralisation. A similar pattern is emerging here at the
Dog-Leg prospect with drilling evidence pointing to a potential flat lying
geometry which may result in additional resource growth (refer Figure 4,
Figure 5 and Figure 6).
Anticipated timing for assay receipt and review is approximately 2 to 3 months
from the date of this announcement.

abundance. All intervening intervals are of schist lithology with no observed
mineralisation. All spodumene-bearing pegmatite intervals occur as sills,
dykes and veins of coarse-grained pegmatite with crystalline textured
disseminated fine to coarse grained spodumene, quartz, feldspar, muscovite and
accessory minerals. Where not visibly spodumene-bearing, the pegmatites occur
as sills, dykes and veins of massive, crystalline coarse-grained quartz,
feldspar, muscovite and accessory minerals.

Atlantic Lithium is an AIM and ASX-listed lithium company advancing a
portfolio of lithium projects in Ghana and Côte d'Ivoire through to
production.
The Company's flagship project, the Ewoyaa Project in Ghana, is a significant
lithium spodumene pegmatite discovery on track to become Ghana's first
lithium-producing mine.
The Definitive Feasibility Study for the Project indicates the production of
3.6Mt of spodumene concentrate over a 12-year mine life, making it one of the
top 10 largest spodumene concentrate mines in the world.
The Project, which was awarded a Mining Lease in October 2023, is being
developed under a funding agreement with Piedmont Lithium Inc.
Atlantic Lithium holds 509km(2) and 774km(2) of tenure across Ghana and Côte
d'Ivoire respectively, comprising significantly under-explored, highly
prospective licences.
