Snapshot	Tulu Kapi Gold Project is the first modern mine in Ethiopia construction ready. The project includes a proposed open pit mine and CIL gold plant. Excellent progress is being made with the intense Early Works programme following Project launch in May 2024 to take Tulu Kapi through to September 2024, and provide the basis for full financial close and commencement of Major Works in October 2024. Tulu Kapi Major Works Program - October 2024 Onwards: • Procurement and fabrication of plant internationally • Site earthworks • Grade-control drilling • Transportation to site and assembly of plant and associated infrastructure • Mining • Definitive Feasibility Study (DFS) on underground mine.

Deposit type

• Intrusion related
• Breccia pipe / Stockwork

Summary:

The region lies within the Arabian-Nubian Shield (AN Shield) which consists of Archaean gneiss and is best described as a granite greenstone terrain. Additional weakly metamorphosed volcano-sedimentary successions of late Proterozoic age occur within the terrain. The area has been extensively folded, faulted and intruded by Pan-African aged granites and lesser mafic to ultramafic intrusions and hosts a number of gold occurrences/deposits.

The gold mineralisation at Tulu Kapi is hosted by an Upper Proterozoic age intrusive, which comprises a coarse grained syenite pluton. These rocks have been intruded into a volcano- sedimentary sequence that was subsequently transformed to mafic and sericitic schists. The main Tulu Kapi deposit comprises a series of stacked gold-bearing quartz-carbonate veins, veinlets and stock work intimately associated with sub-horizontally dipping albite alteration zones.

The Tulu Kapi area is underlain by a volcano-sedimentary sequence rocks ranging in age from Precambrian to Tertiary age. Gold mineralization is associated with a coarse-grained Upper Proterozoic syenite intrusion. The southern and eastern limits of the Tulu Kapi deposit are defined by a northeast-southwest-trending shear zone (Bedele shear zone), which ranges in thickness from 20 m to 60 m and dips to the northwest. The hanging-wall of the shear zone is formed by syenite, which hosts mineralization; diorite forms the footwall contact. Gold mineralization occurs in a series of southeast-dipping zones of quartz-veined, albite alteration that is centered on a north-northeast-trending shear.

The main mineralization stage at Tulu Kapi is composed of an assemblage of hydrothermal minerals that are present in highly variable abundances and include quartz, albite, carbonate, biotite, muscovite, epidote, sulphide and gold. The mineralization commonly occurs in veins, crackle zones and minor breccia zones. The typical Tulu Kapi gold mineralization within the pit is associated with sulphide-bearing albite alteration and quartz veins (replacement and fracture fillings). Albite occurs as overgrowths on original syenite feldspar and also as newly formed crystals in veins and cavities. It is uncertain whether the albite associated with the mineralization is the same stage as the pervasive albitization of the syenite. However, since the albitised syenite is cut by quartz veins that pre-date the mineralisation, it is suspected that the pervasive albitisation is an earlier event. A minor generation of late-stage pyrite veins is weakly developed. The veins are typically less than 10 microns wide and have been observed to crosscut muscovite veins. No gold has been observed in association with these veins.

The sulphide minerals identified include pyrite, sphalerite, bornite, chalcopyrite, galena and arsenopyrite. In addition, tetrahedritetennantite has been tentatively identified. Pyrite is by far the most abundant sulphide and occurs as coarse to fine grained infill and as alteration spots in syenite. Aggregates of small crystals are common and typically these also contain crystals of silicate and carbonate minerals to form a sieve-like texture. Lack of considerable arsenic, antimony and tellurium minerals suggest that the majority of gold could be found as a free gold.
