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.

Deposit type

• Pegmatite

Summary:

Pegmatite-hosted lithium deposits are the target for exploration. This style of mineralisation typically forms as dykes and sills intruding or in proximity to granite source rocks.

The Ewoyaa pegmatites contain relatively consistent amounts of spodumene (within the mineralised zones), quartz, albite, potassic feldspar (“k-feldspar”) and muscovite mica, along with numerous other minerals in relatively minor amounts.

The Ewoyaa 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.

In general, the Ewoyaa Project area is largely underlain by rocks of the Birimian Supergroup, dominated by volcano-sedimentary lithologies of the Cape Coast Basin, situated on the southeast margin of the extensive Cape Coast Granitoid. Three forms of schist are developed in the area; mica schist, staurolite schist and garnet schist; all of which are a blue-grey colour when fresh, with weathering to a brown colour. All of the schist appears to be quartz-biotite rich and well-foliated. The staurolite occurs as 2mm to 20mm porphyroblasts, while the garnets are generally small 1 to 2mm and could be almandine or possibly spessartine within the quartz-mica schist.

Several, presumably Eburnean-aged, granitoids intrude the basin metasediments as small bosses and plugs. These granitoids range in composition from intermediate granodiorite (often medium-grained) to felsic leucogranites (coarse to pegmatoidal grain size), both sometimes in close association with pegmatite veins and bodies.

Several roughly north-south trending dolerite dykes cut through the Birimian schist and the later granitic and pegmatite intrusions and are presumably of Miocene age. The dolerite dykes are some 5 to 30m wide and are easily mapped using the airborne magnetic data and also outcrop in places as rounded float and boulders. A single dolerite dyke cuts through the Abonko area, skirting the east side of the aggregate quarry. In the extreme west of the tenement area, a number of subparallel dolerite dykes extend from the coast northwards through and past the large Afrangwa granitic boss. This north-south trending structural corridor of parallel dolerite dykes appears to host roughly north-south trending elongate granitic intrusive bodies and pegmatites as well as the dolerite dykes.

Dimensions
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.
