The deposits at the Sabodala-Massawa Complex are classified as orogenic gold deposits. At the Sabodala-Massawa Complex, all of the defined mineral resources are within the Sabodala and Massawa exploitation permit areas. The permit areas are transected by two prominent, first order shear zones, the Main Transcurrent Shear Zone (“MTZ”) and the Sabodala-Sofia Zone (“SSZ”) both trending north-northeast. Existing deposits and exploration targets are closely associated with these first order structures. Within the Sabodala licence, lithologies generally trend north-northeast to northeast with steep dips. The sequence is dominated by mafic volcanics, with intercalated interflow sediment horizons. On the Massawa licence, the stratigraphy is dominated by a package of volcaniclastic rocks to the west, and a package of greywackes to the east. Bedding typically strikes to the north-northeast with a steep dip of between 75° to 80° toward the west. Several igneous rocks including sills of gabbro, felsic intrusions, and feldspar (and/or quartzfeldspar) porphyries intrude this dominantly clastic sequence. The mineralisation is often associated with quartz shear veins, extension vein arrays, shear zones, and disseminated sulphides. Mineralisation is typically associated with greenschist metamorphic grade and vein dominated styles. The typical mineralogy of the gold-bearing mineralisation is quartz-carbonate ± albite ± K-feldspar veins with up to 10% (pyrite ± arsenopyrite ± base metals) ........

The mining method employed across the Project Area is conventional open pit, excavator and truck operation, with the production unit operations (drilling, blasting, loading, hauling and dumping) carried out by mixed owner-contractor mining personnel and equipment. Load and haul activities are owner operated; ore is/will be transported from the various pits to the SCPF RoM pads, by Transport Dieye; blasting is carried out by Orica; production drilling is carried out by SGO; grade control drilling activities are performed by FTE.

In FY-2023, ore will be sourced primarily from the Sabodala and Bambaraya pits with additional higher grade non-refractory ore expected to be sourced from the Massawa Central Zone and Massawa North Zone pits.

The capacity of the mining fleet owned by SGO and other service providers meets the earthmoving requirements of the mining schedule, as per the LoM plan and budget plan for 2022. The in-pit material excavation is conducted by a fleet of twelve Komatsu excavators (consisting of five 250 t PC3000, four 100 t PC1250 and four PC450).

Material haulage from the pits is undertaken by twenty-four Komatsu HD785-7 rear dump trucks, and nine Caterpillar 777E rear dump trucks. Key items of the ancillary fleet are the eleven Komatsu D375A track dozers, two Komatsu WD600 wheel dozers, one Komatsu D155AX track dozer, five Caterpillar D10T2 dozers, seven GD825A motor graders, and four Komatsu HD265 water trucks.
