HIGHLIGHTS:

Ø Assay results reported for a further 10,679m of exploration and infill diamond drilling ("DD") and reverse circulation ("RC") drilling completed at the Ewoyaa Main, Ewoyaa North-East, Kaampakrom and Grasscutter West deposits, part of the now completed resource evaluation and exploration RC and 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"); extending mineralisation at the Ewoyaa North-East and Ewoyaa Main deposits, defining new mineralisation from surface at the Kaampakrom North deposit and providing further confidence in Resource conversion at the Kaampakrom West deposit.

o  Average annualised US$1,359/dry metric tonne SC6 pricing used

Commenting on the Company's latest progress, Lennard Kolff, Interim Chief Executive Officer of Atlantic Lithium, said:

"Drilling continues to deliver high-grade drill intersections both within and outside the current MRE.

"This latest batch of results has delivered multiple drill intersections outside the resource footprint at the Ewoyaa North-East, Kaampakrom West and Ewoyaa Main deposits, including highlights of 35m at 1.48% Li2O from 111m and 27m at 1.71% Li2O from 155m at the Ewoyaa North-East deposit.

"Drilling has returned high-grade results at the Kaampakrom West deposit, including highlights of 20m at 1.85% Li₂O from 72m, 14m at 1.89% Li₂O from 140m, 14m at 1.89% Li₂O from 140m and 13m at 1.91% Li₂O from 117m, in addition to our highest-grade assay result of 6.78% Li₂O over a 1m interval in drilling at the Ewoyaa Main 'Starter Pit' for this programme.

"We have reported approximately 37,000m of the 47,000m programme to date, with 10,000m of assays pending and a Resource upgrade expected early 2023. 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 10,679m of RC and DD drilling from the recently completed drill programme at the Ewoyaa Project. Multiple high-grade drill intersections are reported for exploration drilling results outside of the currently defined Resource at the Ewoyaa North-East, Kaampakrom West, Ewoyaa Main and Grasscutter West and deposits (refer Table 1, Appendix 1 and Appendix 2).

High-grade infill drill intersections are reported within the Ewoyaa Main and Ewoyaa North-East deposits, which fall within the currently defined 30.1Mt @ 1.26% Li₂O MRE (refer Table 2, Appendix 1 and Appendix 2).

Table 1: High-grade exploration drill intersection highlights at greater than 10 Li x m, reported at a 0.4% Li₂O cut-off and a maximum of 4m internal dilution at the Ewoyaa North-East, Kaampakrom West, Ewoyaa Main and Grasscutter West deposits.

Table 2: High-grade infill drill intersection highlights at greater than 10 Li x m, reported at a 0.4% Li₂O cut-off and maximum of 4m of internal dilution at the Ewoyaa Main and Ewoyaa North-East deposits.

Exploration drilling results outside the 30.1Mt at 1.26% Li₂O Resource continue to demonstrate further resource scale potential at the Ewoyaa Project, where multiple new drilling intersections have confirmed mineralisation extensions at the Ewoyaa North-East, Kaampakrom West, Ewoyaa Main and Grasscutter West deposits (refer Figure 1, Figure 2, Figure 3 and Figure 4).

Resource infill drilling results received to date at the Ewoyaa Main and Ewoyaa North-East deposits have confirmed good mineralisation continuity and increased resource confidence on a nominal 40m x 40m Indicated grid and 20m x 20m Measured grid. Measured drilling targeted the first 1.5 to 2 years of planned production at the Ewoyaa Main deposit. Additionally, infill drilling provided further material for test-work and customer acceptance samples within the planned starter pit.

High grades were reported within the Kaampakrom West deposit including highlights of 20m at 1.85% Li₂O from 72m, 14m at 1.89% Li₂O from 140m, 14m at 1.89% Li₂O from 140m and 13m at 1.91% Li₂O from 117m.

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.
