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.

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.

challenging. The hills are often separated by broad,
