Exploration Update

Assays Continue to Extend Mineralisation Beyond Current Resource

Ewoyaa Lithium Project Ghana, West Africa

Atlantic Lithium Limited (AIM: ALL, OTC: ALLIF, "Atlantic Lithium" or the "Company"), the funded African-focussed lithium exploration and development company targeting to deliver Ghana's first lithium mine, is pleased to announce assay results from the resource and exploration drilling programme currently underway at the Ewoyaa Lithium Project ("Ewoyaa" or the "Project") in Ghana, West Africa.

HIGHLIGHTS:

Ø Assay results received for an additional approximate 2,900m of Reverse Circulation ("RC") drilling completed at the Ewoyaa Main and Grasscutter North targets, part of the ongoing 37,000m resource evaluation and exploration RC and diamond core drilling ("DD") programme.

Ø Broad, high-grade drill intersections returned at the Ewoyaa Main deposit, including highlights of:

o  GRC0667: 69m at 1.34% Li₂O from 129m

o  GRC0666: 67m at 1.2% Li₂O from 112m

o  GRC0670: 59m at 1.07% Li₂O from 125m

o  GRC0669: 59m at 0.95% Li₂O from 113m

Ø Newly reported drilling results fall outside the current Ewoyaa JORC (2012) Compliant Mineral Resource Estimate ("MRE" or the "Resource") and extend mineralisation a further 75m downdip at the Ewoyaa Main deposit, providing confidence in future resource growth potential.

Ø Additional results have extended mineralisation a further 40m west at the Grasscutter North target outside of the current Resource, including GRC0653: 7m at 1.16% Li₂O from 129m, GRC0654: 4m at 1.12% Li₂O from 96m and GRC0655: 9m at 0.68% Li₂O from 157m.

Ø Approximately 27,000m of the planned 37,000m drilling programme completed to date with the remainder planned for completion in Q3 2022.

Ø The Company announced a significant Resource upgrade in March 2022 to 30.1Mt at 1.26% Li₂O for the Ewoyaa Lithium deposit, which represented a 42% increase from the previous MRE. This included 20.5Mt @ 1.29% Li₂O in the Indicated category and was reported in accordance with the JORC Code (2012) (refer RNS of 24 March 2022).

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

"We are pleased to report high-grade pegmatite intervals up to 69m long below the Ewoyaa Main deposit and outside of the currently defined resource estimate. Furthermore, mineralisation remains open along strike and at depth.

"Approximately 27,000m of the planned 37,000m programme at Ewoyaa has now been completed. Drilling is ongoing, with further assays pending and the programme targeted for completion this quarter.

"These latest assays continue to demonstrate the potential for resource growth outside of the current resource and for an extended mine life beyond the metrics of the Scoping Study reported in December 2021 and prior to the updated Resource Estimate of 30.1Mt @ 1.26% Li₂O, announced in March 2022.

"It is clear from Ewoyaa's ongoing positive drilling results, available off take capacity combined with the Pre-Feasibility Study targeted for completion in Q3 2022 and our funding agreement with Piedmont Lithium, we are in an exceptional position to benefit from the continued global lithium demand."

Additional Drilling Results from Ewoyaa Main and Grasscutter North Target

Further assay results have been received for an additional 2,900m of RC drilling from the ongoing resource evaluation and exploration drill programme. Multiple high-grade and broad drill intersections are reported below the Ewoyaa Main deposit, which falls outside of the currently defined 30.1Mt @ 1.26% Li₂O MRE (refer Table 1 and Appendix 1).

Table 1: High-grade drill intersections at greater than 5 Li x m, reported at a 0.4% Li₂O cut-off and maximum of 4m of internal dilution.

Drilling results received to date at the Ewoyaa Main deposit have extended mineralisation a further 75m down dip over significant widths and grades in holes GRC0666, GRC0667, GRC0669 and GRC0670 (refer Figure 1, Figure 2 and Figure 3).

High-grade mineralisation has now been reported below the northern end of the Ewoyaa Main deposit over an approximate 160m strike with true widths between 30m to 75m and extended a further 75m down-dip from the current Resource. Mineralisation occurs outside of the current Resource and remains open along strike and at depth. Drilling is ongoing, with approximately 27,000m of the planned 37,000m programme completed to date.

Assay results received at the Grasscutter North target have extended mineralisation a further 40m to the west in holes GRC0653 (7m at 1.16% Li₂O from 129m), GRC0655 (9m at 0.68% Li₂O from 157m) and GRC0654 (4m at 1.12% Li₂O from 96m) from previously reported intercepts (refer RNS of 23 June 2022). Intervals of 'no intercepts' were reported in error in the RNS of 19 July 2022 for holes GRC0650 to GRC0658 at the Grasscutter North target with newly reported intervals falling outside of the current Resource.

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. The planned 37,000m programme consists of: approximately 13,000m in 124 collars of exploration drilling; 18,000m in 100 collars of resource expansion and Inferred to Indicated infill drilling; 5,000m in 60 collars of Indicated to Measured infill drilling for the first 1.5 years of mine life; and 1,000m in 6 collars of geotechnical diamond drilling. The majority of the programme is RC, with approximately 3,000m to 5,000m of diamond drilling planned.
