Snapshot	The Ewoyaa Lithium Project comprises the proposed Ewoyaa Lithium Mine and Processing Plant. On 20 October 2023, the Atlantic Lithium announced that Ghana’s Ministry of Lands and Natural Resources had granted a Mining Lease in respect of the Ewoyaa Lithium Project. Key financial terms, agreed under the grant of the Mining Lease, have been updated from those considered as part of the Definitive Feasibility Study for the Project (29 June 2023). During the period ended 31 December 2023, Atlantic Lithium Completed of the Flotation Scoping Study. The Company intends to commence construction of the flotation circuit once the main plant consistently delivers its intended nameplate throughput of 2.7Mt per annum. Ewoyaa is now on track to become a top 10 hard rock spodumene concentrate mine.

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.

Surface geology within the Project area typically consists of sequences of staurolite and garnet-bearing pelitic schist and granite with lesser pegmatite and mafic intrusives. Outcrops are typically sparse and confined to ridge tops with colluvium and mottled laterite blanketing much of the undulating terrain making geological mapping challenging. The hills are often separated by broad, sandy drainages.

The mineralised pegmatite intrusions generally occur as sub-vertical bodies with two dominant trends as briefly outlined earlier: either striking north-northeast (Ewoyaa Main) and dipping sub-vertically to moderately southeast to east-southeast, or striking west-northwest to east-west (Abonko, Kaampakrom, Anokyi, Okwesi, Grasscutter and Ewoyaa Northeast) dipping sub-vertically to moderately northeast or north. Pegmatite thickness varies across the Project, with thinner mineralised units intersected at Abonko and Kaampakrom between 4m and 12m; and thicker units intersected at Ewoyaa Main between 30m and 60m, and up to 100m at surface.

The mineralisation at Ewoyaa has been confirmed to be associated with spodumene-bearing pegmatite as the main lithium bearing mineral. No petalite or lepidolite have been observed in any of the resource RC and diamond core drill logging. The pegmatites are predominantly quartz-albite-muscovite +/- microcline and spodumene in composition with accessory blue-green apatite, and less common colourless to light blue beryl, barite and secondary Fe-Mn-Li bearing phosphates.

The Project has two clearly defined geometallurgical domains or material types of spodumene bearing lithium mineralisation. Atlantic Lithium has termed these material types as Pegmatite Type (“P1”) and Pegmatite Type (“P2”):
- P1: Coarse grained spodumene material (>20mm), the dominant spodumene-bearing pegmatite encountered to date, exhibiting very coarse to pegmatoidal, euhedral to subhedral spodumene crystals composing 20 to 40% of the rock and
- P2: Medium to fine grained spodumene material (<20mm), where abundant spodumene crystals of a medium crystal size dominates. The spodumene is euhedral to subhedral and can compose up to 50% of the rock. The spodumene can be bimodal with some larger phenocrysts entrained within the medium grained spodumene bearing matrix. There are indications of very minor occurrences of other lithium bearing phases present.

The vast majority of the finer grained spodumene P2 ore is found within the Ewoyaa Main pegmatite bodies and preferentially occurring towards the footwall contact of the Ewoyaa Main pegmatites, but with some exceptions. Any finer grained spodumene P2 pegmatite material occurring in the Abonko trending pegmatite bodies are generally rare and of limited extent.

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.
