Snapshot	The Ewoyaa Lithium Project has secured all necessary permits for construction, including the Mine Operating Permit, Land Use Certificate, and Water Use Permit, marking the final regulatory steps before mining begins. Atlantic Lithium Ltd. awaits ratification of the Ewoyaa Mining Lease by Ghana’s parliament. Technical refinements with DRA Projects have optimized plant design, clarified capital expenditure, and confirmed tailings can be dry-stacked, eliminating the need for a Tailings Storage Facility. The team is finalizing key contracts to support the Board’s Final Investment Decision (FID). The updated Mineral Resource Estimate confirms feldspar, based on the same model as the Li2O estimate, supporting cost reductions, local ceramics supply, and successful metallurgical testing. DFS optimisation provides key insights into project funding and commercial production. The Project remains on track to become Ghana’s first lithium mine and a major global spodumene producer.

Summary:

The Ewoyaa Project area lies within the Birimian Supergroup, a Proterozoic volcano-sedimentary basin located in Western Ghana. The Project area is underlain by three forms of metamorphosed schist; mica schist, staurolite schist and garnet schist. Several granitoids intrude the basin metasediments as small plugs. These granitoids range in composition from intermediate granodiorite (often medium grained) to felsic leucogranites (coarse to pegmatoidal grain size), sometimes in close association with pegmatite veins and bodies. Pegmatite intrusions generally occur as sub-vertical dykes with two dominant trends: either east-northeast (Abonko, Asan, Kaampakrom and Ewoyaa Northeast) dipping sub-vertically northeast; or north-northeast (Ewoyaa Main) and dip sub-vertically to moderately southeast to east-southeast. Pegmatite thickness varies across the Project, with thinner mineralised units intersected at Abonko and Kaampakrom between 4 and 12m; and thicker units intersected at Ewoyaa Main between 30 and 60m, and up to 100m at surface.

The Project area has two clearly defined material types of spodumene bearing lithium mineralisation. The Company has termed these material types as Pegmatite Type 1 (“P1”) and Pegmatite Type 2 (“P2”). P1 material is characterised by coarse grained spodumene bearing pegmatite which exhibits very coarse to pegmatoidal, euhedral to subhedral spodumene crystals. P2 material consists of medium grained spodumene, euhedral to subhedral in shape and can compose up to 50% of the rock. The two material types have different metallurgical recoveries.

The Project Mineral Resource area extends over a north-south strike length of 4,390m (from 577,380mN – 581,770mN), and includes the 360m vertical interval from 80mRL to -280mRL.
