HIGHLIGHTS:
Ø Assay results reported for 5,668m of infill and exploration reverse circulation ("RC") drilling completed at the Ewoyaa Main, Grasscutter East, Grasscutter West and Anokyi deposits, part of the now-completed resource evaluation and exploration RC and diamond drilling ("DD") programme.
Ø Newly reported drilling results fall both within and outside the currently defined 30.1Mt @ 1.26% Li2O Ewoyaa JORC (2012) Compliant Mineral Resource Estimate ("MRE" or the "Resource"), providing further confidence in Resource conversion at the Ewoyaa Main deposit, and extending mineralisation downdip at the Grasscutter East, Grasscutter West and Anokyi deposits.
Commenting on the Company's latest progress, Lennard Kolff, Interim Chief Executive Officer of Atlantic Lithium, said:
"We are delighted to report ongoing high-grade drill intersections, both within the infill programme targeting conversion of Indicated to Measured resources and within the exploration programme targeting resource growth outside the current MRE.
"The latest infill drilling results from within the current Resource at the Ewoyaa Main deposit have returned multiple high-grade pegmatite intervals over 1.5% Li2O and up to 95m long with the hole ending in mineralisation, providing further confidence in future Resource to Reserve conversion.
"Exploration drilling outside of the current Resource has returned multiple intersections, including highlights of 29m at 1.72% Li2O and 25m at 1.49% Li2O at the Anokyi deposit, 45m at 1.16% Li2O at the Grasscutter West deposit and 23m at 1.18% Li2O at the Grasscutter East deposit. These results reaffirm the significant growth potential at the Ewoyaa Project, which we hope to unlock.
"We are thrilled to report our highest-grade RC drilling result to date at the Ewoyaa Project of 4.52% Li2O over 1m, including an adjacent 1m interval of 3.99% Li2O in infill drilling at the Ewoyaa Main deposit.
"We anticipate further news flow from pending drilling results into the end of the year and are targeting a Resource upgrade at the end of 2022 or early 2023, dependent on lab turn-around time. The increased Resource estimate will inform a Definitive Feasibility Study, targeted for completion in mid-2023.
"With the Pre-Feasibility Study now delivered, the Mining Licence application submitted, ongoing positive drilling results and with the support of our funding agreement with Piedmont Lithium, we feel the Company is ideally positioned to benefit from the unprecedented levels of lithium demand that are expected over the coming years."
New Drilling Results:
Further assay results have been received for an additional 5,668m of RC drilling from the recently completed drill programme at the Ewoyaa Project. Multiple high-grade and broad infill 'Measured' drill intersections are reported within the Ewoyaa Main deposit, which falls within the currently defined 30.1Mt @ 1.26% Li2O MRE (refer Table 1, Appendix 1 and Appendix 2). Additionally, multiple drill intersections are reported for exploration drilling results outside of the currently defined Resource (refer Table 2, Appendix 1 and Appendix 2).

Resource infill drilling results received to date at the Ewoyaa Main deposit have confirmed mineralisation continuity and ability to convert from Inferred and Indicated resources to Measured resources on a nominal 20m x 20m grid. Measured drilling targeted the first 1.5 to 2 years of planned production at the Ewoyaa Main deposit and was planned to provide Proven Reserves in support of the Definitive Feasibility Study, in addition to further material for test-work and customer acceptance samples within the planned starter pit.
High grades over broad intervals were reported from near surface within the proposed starter pit zone of the Ewoyaa Main deposit, including highlights of 95m at 1.48% Li2O from 5m, 87m at 1.61% Li2O from surface, 78m at 1.67% Li2O from 12m and 74m at 1.65% Li2O from 15m (refer Figure 1 and Figure 2).
Exploration drilling results outside the 30.1Mt at 1.26% Li2O Resource continue to demonstrate further resource scale potential at the Ewoyaa Project, where new drilling results have returned highlights of 45m at 1.16% Li2O at the Grasscutter West deposit, 29m at 1.72% Li2O and 25m at 1.49% Li2O at the Anokyi deposit and 23m at 1.18% Li2O at the Grasscutter East deposit (refer Figure 1, Figure 3 and Figure 4).
The highest-grade meter interval reported to date in RC drilling of 4.52% Li2O, including an adjacent 1m downhole interval of 3.99% Li2O was achieved in hole GRC0704 between 53m to 55m at the Ewoyaa Main deposit. The mineralisation occurs within a larger reported interval of 23m at 1.4% Li2O from 36m in hole GRC0704 as part of the infill programme and demonstrates the high grades present at the deposit.
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
Atlantic Lithium (formerly "IronRidge Resources") 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 Company signed a funding agreement with Piedmont Lithium Inc. for US$103m towards the development of the Ewoyaa Project. Based on the Pre-Feasibility Study, the Ewoyaa Project has indicated Life of Mine revenues exceeding US$4.84bn, producing a spodumene concentrate via simple gravity only process flowsheet.
Atlantic Lithium holds 560km2 & 774km2 of tenure across Ghana and Côte d'Ivoire respectively, comprising significantly under-explored, highly prospective licenses.
