SnapshotThe Mimosa operation comprises a shallow underground mine, accessed by two decline and one small vertical shafts, and a concentrator.

The North Hill project will extend Mimosa’s life-of-mine by circa 10 years. The feasibility study was completed. During FY2024, a decision was taken not to progress the North Hill operation in the current pricing environment, which will impact on life-ofmine at Mimosa. Efforts are focused on the current operations to improve efficiencies and options are evaluated to extend its life-of-mine.

Summary:

PGM mineralisation at Mimosa is located in four isolated and fault-bounded blocks - from north to south they are the North Hill, South Hill, Mtshingwe Fault Block and Far South Hill mineralised bodies.

Each block is host to a pyroxenite layer known as the P1 pyroxenite layer, overlain by a gabbro layer. The platinum-bearing Main Sulphide Zone (MSZ) is located in the P1 pyroxenite, some 10m below the ultramafic/mafic contact. The MSZ is a continuous layer, 2m to 6m thick, and forms an elongated basin. The mineralised zone strikes in a north-northeasterly trend and dips at about 14° on the margins, flattening towards the central part of the orebody. The MSZ at Mimosa has a well-defined grade profile where peak base metal and PGM values are offset vertically, with palladium dominant towards the base, platinum in the centre and nickel towards the top. The MSZ is visually identified using pyroxene and sulphide mineralisation. Minor faults and dykes are present and although no potholes have been identified, low- grade areas and areas of no mineralisation, or ‘washout channels’, have been intersected.
