8,000m of Additional Resource Extension Drilling Planned
Resource and Metallurgical Drilling Results
Drilling Returns High-grade Infill & Extensional Intersections
Ewoyaa Lithium Project, Ghana, West Africa
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 the addition of 8,000m of drilling targeting resource growth to the
ongoing 2023 programme and further assay results from the resource and
metallurgical drilling programme underway at the Ewoyaa Lithium Project
("Ewoyaa" or the "Project") in Ghana, West Africa.
Highlights:
- Ongoing drilling programme increased by 43% with the addition of
8,000m of extensional resource drilling targeting resource growth following
the grant of the Mining Lease for the Project.
o Planned 18,500m programme increased to a total of 26,500m targeted for
completion in Q2 2024, of which 16,164m has been reported to date, including
the results reported herewith.
- Further assay results received for 2,362m of resource and
metallurgical reverse circulation ("RC") and diamond core ("DD") drilling
completed at Ewoyaa as part of the broader 2023 planned drilling programme.
- High-grade infill and extensional drill intersections reported at
the Ewoyaa Main, Anokyi and Ewoyaa South-2 deposits designed to provide
metallurgical drill core whilst infilling the resource and extend
mineralisation.
o Reported assay results extend mineralisation at the Ewoyaa Main deposit,
outside of the current 35.3Mt @ 1.25% Li(2)O Ewoyaa Mineral Resource
Estimate(1) ("MRE" or the "Resource") in hole GDD0093.
o Shallow high-grade infill drill intersections at Ewoyaa Main, Anokyi and
Ewoyaa South-2 reported as downhole intercepts, with estimated true widths
included in the intersections table, including highlights at a 0.4% Li(2)O
cut-off and a maximum 4m of internal dilution of:
o GDD0105: 47.6m at 1.25% Li(2)O from 65.7m
o GDD0107C: 53m at 0.93% Li(2)O from 30m
o GDD0109: 28.7m at 1.51% Li(2)O from 79.3m
o GDD0104: 28.2m at 1.23% Li(2)O from 81.2m
o GDD0106: 22.4m at 1.07% Li(2)O from 34m
o GDD0110: 14m at 1.46% Li(2)O from 33m
Commenting on the Company's latest progress, Neil Herbert, Executive Chairman
of Atlantic Lithium, said:
"We are pleased to report that a further 8,000m of drilling has been planned
across the Ewoyaa Lithium Project in addition to the existing 18,500m
programme. This planned drilling, which will bring the total programme to
approximately 26,500m of infill, extensional, exploration and studies
drilling, follows the recent grant of the Mining Lease for the Project and
represents the commencement of an escalation in the Company's exploration
efforts, which will go into Q2 2024, focused on growing the Ewoyaa Resource.
"At the same time, we continue to deliver impressive assay results from the
ongoing programme. These latest results from the Ewoyaa Main, Anokyi and
Ewoyaa South-2 deposits have returned multiple high-grade and broad infill
intersections, including 47.6m at 1.25% from 65.7m and 28.7m at 1.51% Li(2)O
from 79.3m, which increase the confidence in the current Resource, whilst we
have extended mineralisation beyond the Resource envelope in hole GDD0093,
which intersected 15.5m at 0.83% Li(2)O from 182.7m at Ewoyaa Main, where
mineralisation remains open at depth.
"We look forward to updating shareholders on our ongoing progress, including
as remaining assay results become available."
Expanded Drilling Programme
The 2023 drilling programme has been expanded with an additional approximate
8,000m of RC drilling planned for resource depth and strike extensions at the
Okwesikrom, Anokyi, Grasscutter, Ewoyaa North-West and Ewoyaa South-2 deposits
(refer Figure 1). The total programme now stands at approximately 26,500m with
16,164m reported to date and drilling targeted to be completed in Q2 2024.

New Drilling Results
Further assay results have been received for 2,362m of RC and DD drilling from
the ongoing metallurgical, extensional and infill drill programme at the
Ewoyaa Lithium Project. High-grade metallurgical drilling results have been
reported at the Ewoyaa Main, Anokyi and Ewoyaa South-2 deposits, also serving
as infill resource holes. Further high-grade drill intersections have been
reported for an extensional drilling result at the Ewoyaa Main deposit which
sits outside of the current MRE(1) (refer Table 1, Table 2, Appendix 1 and
Appendix 2).
Drilling aims to intersect mineralised pegmatite dykes perpendicular to strike
and dip to approximate true width. This is not always achieved due to the
variable nature of pegmatites or challenging drill access, with some drill
intersections drilled down-dip as apparent widths. Accordingly, estimated true
widths are included in the intersections table in Appendix 1.
Further metallurgical studies infill and extensional drilling results have
confirmed mineralisation continuity and extended mineralisation at depth
outside of the current MRE respectively (refer Figure 2, Figure 3 and Figure
4), including highlight intersections at a 0.4% Li(2)O cut-off and a maximum
4m of internal dilution shown in Table 1.

Further high-grade drill intersections are reported for metallurgical drilling
at the Ewoyaa Main, Anokyi and Ewoyaa South-2 deposits, providing drill core
for future test-work as well as confirming mineralisation continuity within
the current MRE as infill drilling results. High-grade and broad and shallow
intersections include holes GDD105: 47.6m at 1.25% Li(2)O from 65.7m, GDD107C:
53m at 0.93% Li(2)O from 30m and GDD106: 22.4m at 1.07% Li(2)O from 34m (refer
Figure 2, Figure 3 and Figure 4).
Mineralisation has also been extended outside of the current MRE in hole
GDD0093: 15.5m at 0.83% Li(2)O from 182.7m and 13.2m at 0.74% Li(2)O from
217.5m as depth extensions within the Ewoyaa Main deposit providing potential
for further Resource(1) growth at depth (refer Figure 2 and Figure 5).
Sample preparation was completed by Intertek Ghana and assay by Intertek
Perth, with all reported results passing QA/QC protocols, providing confidence
in reported results.

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 560km(2) and 774km(2) of tenure across Ghana and Côte
d'Ivoire respectively, comprising significantly under-explored, highly
prospective licences.
