Multiple Broad and High-Grade Drill Intersections
Resource Extension Drilling Results
Ewoyaa Lithium Project, Ghana, West Africa
83m at 1% Li(2)O from 36m Returned at Dog-Leg Target
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 further broad and high-grade assay results from the resource drilling
completed during 2023 at the Company's flagship Ewoyaa Lithium Project
("Ewoyaa" or the "Project") in Ghana, West Africa.
Highlights:
- Further assay results received for 7,220m of extensional resource
reverse circulation ("RC") drilling completed at Ewoyaa as part of the ongoing
2023/2024 drilling programme.
- Multiple high-grade and broad extensional drill intersections
reported at the new Dog-Leg target, Okwesi, Anokyi and Ewoyaa-South 2 deposits
outside of the current 35.3Mt @ 1.25% Li(2)O Ewoyaa Mineral Resource
Estimate(1) ("MRE" or the "Resource"), including highlights at a 0.4% Li(2)O
cut-off and a maximum 4m of internal dilution of:
o GRC1020: 83m at 1% Li(2)0 from 36m
o GRC1017: 47m at 1.05% Li(2)O from 87m
o GRC0996: 24m at 1.21% Li(2)O from 29m
o GRC0994: 11m at 1.9% Li(2)O from 105m
o GRC1023: 24m at 0.81% Li(2)O from 159m
o GRC1020: 21m at 0.87% Li(2)O from 139m
o GRC0989: 12m at 1.49% Li(2)O from 108m
o GRC0983: 12m at 1.34% Li(2)O from 38m
o GRC1000: 9m at 1.68% Li(2)O from 22m
- Results at Dog-Leg are significant; drilling has intersected
shallow dipping, near surface mineralised pegmatite bodies with true
thicknesses up to 35m outside of the MRE, proving potential for significant
resource growth.
- Drilling to recommence shortly; prioritisation of the recently
added 3,000m plant site sterilisation programme in support of mine site
commissioning, ahead of completion of the remaining 26,500m resource growth
and infill programme commenced in 2023.
Commenting on the Company's latest progress, Neil Herbert, Executive Chairman
of Atlantic Lithium, said:
"We are pleased to deliver further impressive assay results from drilling
completed in 2023, part of the ongoing programme. These latest results from
the new Dog-Leg target, Okwesi, Anokyi and Ewoyaa South-2 deposits have
returned multiple high-grade and broad extensional intersections, including
83m at 1% Li(2)O from 36m and 47m at 1.05% Li(2)O from 87m at the new Dog-Leg
target.
"All reported drilling results fall outside of the current MRE; pertinent in
that they occur both within a new mineralised area at the Dog-Leg target and
near surface at both the Dog-Leg target and Ewoyaa-South 2 deposit strike
extension.
"We are excited to re-commence drilling for the 2024 season with an initial
focus on 3,000m of sterilisation drilling at the proposed plant site and then
the remaining meterage of the ongoing 26,500m resource drilling programme
targeting Resource growth and conversion.
"We look forward to updating shareholders on our ongoing progress, including
as remaining assay results for drilling completed during 2023 become
available."
New Drilling Results
Further assay results have been received for 7,720m of RC drilling from the
ongoing 2023 drill programme at the Ewoyaa Lithium Project. Broad high-grade
extensional drilling results have been reported at the new Dog-Leg target and
Okwesi, Anokyi and Ewoyaa South-2 deposits. The reported results sit outside
of the current MRE(1) (refer Table 1, Table 2, Appendix 1 and Appendix 2).
Further extensional drilling results have defined new mineralisation at the
Dog-Leg target and extended mineralisation at depth outside of the current
MRE(1) at the Okwesi, Anokyi and Ewoyaa-South 2 deposits (refer Figure 1,
Figure 2, Figure 3 and Figure 4) respectively, including highlight
intersections at a 0.4% Li(2)O cut-off and a maximum 4m of internal dilution
shown in Table 1.
Drilling aims to intersect mineralised pegmatite bodies 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.

Broad and high-grade drill intersections are reported for resource drilling at
the new Dog-Leg target in addition to extensional resource drilling at the
Okwesi, Anokyi and Ewoyaa South-2 deposits.
New drilling at the Dog-Leg target (refer announcement of 28 November 2023)
has delivered broad and high-grade drill intersection, some of which occur
near surface and all occurring outside of the current MRE(1). Highlights
include hole GRC1020: 83m at 1% Li(2)0 from 36m and hole GRC1017: 47m at 1.05%
Li(2)O from 87m (refer Figure 1, Figure 2 and Figure 3).
The results are significant in that an apparent shallow dipping mineralised
pegmatite body has been intersected in multiple drill holes with true widths
of 20m to 35m which has the potential to add significant near surface resource
tonnes.

highlights in holes GRC0996: 24m at 1.21% Li(2)O from 29m, GRC0983: 12m at
1.34% Li(2)O from 38m and GRC1000: 9m at 1.68% Li(2)O from 22m providing
potential for further resource growth near surface (refer Figure 1 and Figure

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
