New Dog-Leg Target Delivers Increase to Ewoyaa MRE

Drilling at the new Dog-Leg target increases the Mineral Resource Estimate
for the Ewoyaa Lithium Project to 36.8Mt at 1.24% Li2O

Atlantic Lithium Limited (AIM: ALL, ASX: A11, GSE: ALLGH, 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 an increase to the JORC (2012) compliant Mineral Resource Estimate (“MRE” or “Resource”) at the Company’s flagship Ewoyaa Lithium Project (“Ewoyaa” or the “Project”) in Ghana, West Africa.

Highlights

• Total Mineral Resource Estimate for the Company’s flagship Ewoyaa Lithium Project increased to 36.8Mt at 1.24% Li2O, reported in accordance with the JORC Code (2012).
• 81% of the Total Resource now in the higher confidence Measured and Indicated categories (3.7Mt at 1.37% in the Measured category, 26.1Mt at 1.24% in the Indicated category and 7.0Mt @ 1.15% Li₂O in the Inferred category).
• MRE increase follows targeted drilling programme, undertaken in 2023 and H1 2024, comprising sterilisation drilling to support the plant and haul road design and resource conversion drilling, converting Inferred resources to Indicated and Measured resources, to provide mine plan optionality; new Dog-Leg target identified through this process.
• Drilling subsequently undertaken on the Dog-Leg target, where the Company has identified a shallow-dipping, near-surface mineralised pegmatite body with true thickness up to 35m, which contributed 890,892 tonnes of the Resource increase to 36.8Mt at 1.24% Li2O.
• Potential to grow the Resource further; step-out drilling planned at five priority deposits and one new exploration target identified for initial reverse circulation (“RC”) evaluation.

Commenting, Neil Herbert, Executive Chairman of Atlantic Lithium, said:

“We are pleased to report an increase in the Mineral Resource for the Ewoyaa Lithium Project to 36.8Mt at 1.24% Li2O, which reaffirms Ewoyaa’s status as one of the leading hard rock lithium projects.

“The increase follows the limited drilling programme completed recently, which was focused on supporting our mine planning activities rather than expanding the resource base, but through which we identified the Dog-Leg target, which has added near-surface tonnes to the Ewoyaa Resource. We are pleased to see this lucky strike at Dog-Leg contributing an additional circa 891,000 tonnes to the enlarged 36.8Mt at 1.24% Li2O Resource.

“While our current focus remains firmly on advancing Ewoyaa towards shovel-readiness, we recognise the significant potential across our exploration portfolio to increase the Resource further.”
