Further Broad and High-Grade Drill Intersections
Resource Extension Drilling Results
Ewoyaa Lithium Project, Ghana, West Africa
69m at 1.25% Li(2)O from 45m returned at Dog-Leg target, outside of current
MRE(1)
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 resource drilling
completed at the Company's flagship Ewoyaa Lithium Project ("Ewoyaa" or the
"Project") in Ghana, West Africa.
Highlights:
- Further assay results received for 2,514m of extensional resource
reverse circulation ("RC") drilling completed at the Dog-Leg target,
representing the final results from drilling undertaken in 2023, with a total
of 25,898m drilled throughout the year.
- Multiple high-grade and broad extensional drill intersections
reported at the new Dog-Leg target outside of the current 35.3Mt @ 1.25%
Li(2)O JORC (2012) compliant 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 GRC1024: 69m at 1.25% Li(2)O from 45m
o GRC1027: 34m at 1.02% Li(2)O from 160m
o GRC1024: 22m at 0.85% Li(2)O from 141m
o GRC1030: 16m at 1.08% Li(2)O from 111m
o GRC1032: 12m at 1.11% Li(2)O from 83m
- 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(1), proving potential for significant
resource growth.
- The Company is advancing the drilling programme to be undertaken
in 2024:
o Plant site sterilisation drilling now completed for a total of 3,177m in
21 holes, with no mineralisation intersected, providing confidence in the
proposed plant site location.
o A further 804m of RC drilling and 70m of diamond core drilling recently
completed at Dog-Leg, with assay results pending.
o Further resource extension and exploration drilling planned alongside
ongoing regional exploration.
- MRE upgrade, for both lithium and feldspar, to incorporate all
2023 and 2024 drilling, targeted for H2 2024.
Commenting on the Company's latest progress, Neil Herbert, Executive Chairman
of Atlantic Lithium, said:
"The final assay results from drilling completed in 2023 have again delivered
impressive intersections, providing further confidence in the growth potential
of the current 35.3Mt @ 1.25% Li(2)O Resource at the Ewoyaa Lithium Project.
"These results are from the new mineralised area at the Dog-Leg target,
located on the northern tip of the Ewoyaa Main deposit, outside of the current
MRE, where drilling has returned multiple high-grade and broad near surface
extensional intersections, including 69m at 1.25% Li(2)O from 45m. This
follows the intersection of 83m at 1% Li(2)O from 36m in hole GRC1020 reported
at Dog-Leg last month.
"On the back of the encouraging results delivered from drilling completed in
2023 at Dog-Leg, we are excited to have recently completed a further 874m of
resource extension drilling at the target as part of our resource growth
programme for 2024. We look forward to receiving further drilling results and
delivering a MRE upgrade for the Project, targeted for H2 2024. The MRE
upgrade will include updates to both the lithium and feldspar and incorporate
all of the results received from drilling completed in 2023 and results
pending for 2024.
"In addition, we are pleased to have recently completed the plant site
sterilisation programme without any surprises, allowing us to continue with
our mine site designs and permitting.
"We look forward to updating shareholders on our ongoing progress."
New Drilling Results
Further and final assay results have been received for 2,514m of RC drilling
from drilling completed in 2023 at the Ewoyaa Lithium Project. A total of
25,898m of drilling in 157 holes were completed throughout the year; all of
which have now been reported. In these latest results, broad high-grade and
near surface extensional drilling results have been reported at the new
Dog-Leg target. The reported results sit outside of the current MRE(1) (refer
Table 1, Figure 1, Figure 2, Figure 3, Appendix 1 and Appendix 2).
Drilling aimed 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.

Note: Metal content is based on intercept rather than estimated true width
New drilling at the Dog-Leg target (refer announcement of 28 November 2023)
has delivered broad and high-grade drill intersections, some of which occur
near surface and all occurring outside of the current MRE(1). Highlights
include hole GRC1024: 69m at 1.25% Li(2)O from 45m and hole GRC1027: 34m at
1.02% Li(2)O from 160m (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.

Additionally, the Company has completed 3,177m of sterilisation drilling in 21
holes at the proposed plant site. No significant mineralisation was observed
in drilling, providing confidence in the proposed plant site location.
The Company has also completed a further 804m of RC drilling and 70m of
diamond resource extension drilling at the Dog-Leg target with assays pending.
The rig has now been demobilised, with drilling planned to recommence in H2
2024.
Meanwhile, regional exploration programmes will continue to advance the
exploration project pipeline. The Company will incorporate the results of
drilling completed in 2023 and results pending for 2024 into a MRE upgrade for
the Project, targeted during H2 2024.
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.

About Atlantic Lithium
www.atlanticlithium.com.au (http://www.atlanticlithium.com.au/)
Atlantic Lithium is an AIM and ASX-listed lithium company advancing its
flagship project, the Ewoyaa Lithium Project, a significant lithium spodumene
pegmatite discovery in Ghana, through to production to become the country'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
largest spodumene concentrate mines in the world.
The Project, which was awarded a Mining Lease in October 2023, is being
developed under an earn-in agreement with Piedmont Lithium Inc.
Atlantic Lithium holds a portfolio of lithium projects within 509km(2) and
774km(2) of granted and under-application tenure across Ghana and Côte
d'Ivoire respectively, which, in addition to the Project, comprises
significantly under-explored, highly prospective licences.
