Exploration Update

High-Grade and Broad Drill Intersections

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 additional assay results from the ongoing resource and exploration drilling programme at the Ewoyaa Lithium Project ("Ewoyaa" or the "Project") in Ghana, West Africa.

Figures and Tables referred to in this release can be viewed in the PDF version available via this link: http://www.rns-pdf.londonstockexchange.com/rns/9420S_1-2022-7-19.pdf

HIGHLIGHTS:

Ø Assay results received for an additional 4,000m of Reverse Circulation ("RC") drilling completed at the Ewoyaa Main and Grasscutter North targets.

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

o  GRC0665: 46m at 1.21% Li2O from 115m

o  GRC0668: 43m at 1.08% Li2O from 126m

o  GRC0672: 31m at 1.43% Li2O from 179m

o  GRC0666: 10m at 1.39% Li2O from 112m*

*mineralisation open at depth; further assays pending

Ø Newly reported drilling results fall outside the current 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 Approximately 24,900m of the planned 37,000m resource evaluation and exploration RC and diamond core drilling ("DD") programme completed to date and planned for completion in Q3 2022.

Ø Approximately 8,560m of assay results reported to date from the ongoing 37,000m planned drilling programme; ongoing news flow of drill results.

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 ongoing and significant high-grade pegmatite intervals over broad widths below the Ewoyaa Main deposit and outside of the currently defined resource volume, giving us confidence to deliver future resource upgrades for the Project.

"Remaining assays are pending for holes GRC0666 and GRC0667 which have long intervals of visible spodumene reported and initial high-grade results received of 10m at 1.39% Li2O in GRC0666 with mineralisation open at depth.

"Drilling at the Ewoyaa project is ongoing, with approximately 24,900m of the planned 37,000m programme completed to date, with further assays pending and the programme targeted for completion this quarter.

"Our ongoing exploration programme demonstrates considerable scope for resource growth and the potential for an extended mine life beyond the metrics of the Scoping Study. This, in conjunction with further economic benefits from increased spodumene concentrate pricing, continue to demonstrate Ewoyaa as an industry-leading asset.

"With the Pre-Feasibility Study targeted for completion in Q3 2022, and the Project being funded to production through our agreement with Piedmont Lithium, we feel the Company is ideally positioned to benefit from the growing lithium demand."

Additional Drilling Results Grasscutter North and Ewoyaa Main Target

Assay results have been received for an additional 4,000m of RC drilling from the planned 37,000m resource evaluation and exploration drill programme, which remains ongoing. 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 3m 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 GRC0665 and GRC0668 (refer Figure 1 and Figure 2).

Initial assay results in hole GRC0666 have confirmed further mineralisation along strike within this area with assay results pending for the remainder of the hole. Further assays are pending, including for visible spodumene zones up to 80m long observed in holes GRC666, GRC667, GRC669 and GRC670 below the Ewoyaa Main deposit (refer RNS of 26 May 2022). Drilling is ongoing, with approximately 24,900m of the planned 37,000m programme completed to date.

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.
