Matla has three major LoM projects which will provide mining access to ~83% of the remaining Coal Reserves when completed. The projects are at different levels of implementation, with delays due to funding and project execution. |

Summary:
Matla mine is situated in the Highveld coalfield, to the south of the Witbank coalfield. The coal seams are developed in the Vryheid Formation of the Karoo supergroup. The stratigraphic sequence in the Matla area includes five coal seams that can be easily correlated with seams found in the Witbank coalfield.
The principal economic seams currently exploited are S2 and S4 with mining of S5 terminated in 1998 due to high levels of contamination and a subsequent increase in the abrasive index.
Coal seams in the area are generally flat and continuous with subsequent igneous activity resulting in displacements and devolatilisation of coal seams in localised areas. The S5 is most prominent in the Mine 2 and Mine 3 areas and, to a limited extent, in the western limb of the southern part of the mining right area. The roof comprises approximately 0.5m of thick sandy micaceous shale at Mine 2 that thickens up to approximately 1.6m in Mine 3. The seam consists of mixed coal and torbanitic material with an average thickness of 1.5m. Economic S4 exists in the Mine 1, Mine 2 and Southern Reserve areas, and to a limited extent in the Mine 3 area. At Mine 3, the seam splits into two thin, poor-quality horizons towards the west, and is thus excluded from the mineable reserves. The best quality S4 is located at Mine 1 and at the eastern edges of Mine 2. The seam is composed of dull lustrous coal interspersed with bright coal bands. In-seam partings typically consist of d ........

Summary:
Matla comprises three underground production facilities: Mine 1, Mine 2 and Mine 3. All three are long- life assets, each with a specific operating capacity comprising conventional coal circuits to produce bituminous coal. Production at Mine 1 was stopped in 2015 due to pillar instability and is planned to resume in 2025. Mine 2 and Mine 3 use bord-and-pillar methods to mine S2 and S4. Shortwall mining is also utilised to conduct mining of S2 in Mine 2.
Matla has three major LoM projects which will provide mining access to ~83% of the remaining Coal Reserves when completed. The projects are at different levels of implementation, with delays due to funding and project execution. The projects include a boxcut and associated declines to access mineable areas at Mine 1 from the surface and an incline and decline project to create underground interseam access at Mine 2 and Mine 3.
