SnapshotModikwa Platinum Mine (MPM) specializes in the extraction of platinum group metals (PGMs).

Both the UG2 and Merensky reefs are present at MPM. The UG2 Reef is mined using underground and open-pit methods. In 2025, the open-pit section was established. The Merensky Reef is mined using the underground method.

South 2 shaft project
The underground-to-surface conveyor belt that connects South 2 infrastructure to South 1 shaft is 85% complete.

Summary:

The Bushveld layered sequence around Modikwa strikes north-northwest to south-southeast and dips to the south-west at 10º to 12º, with local variations in the dip resulting in gradients of nearly 20º. There are several instances where some gentle “rolling” of the reef horizons have been recorded, and normally steeper dips are noted nearer the outcrop (as opposed to at depth).

The outcrop positions of the Merensky Reef and the UG2 Reef normally occur within the areas of low relief, and much of the outcrop is masked by extensive development of black turf as well as, in places, transported sediments. On the farms Maandagshoek 254 KT, Onverwacht 292 KT and Winterveld 293 KT; however, the UG2 Reef (and occasionally the Merensky Reef) outcrops in a series of elongated hills. Although frequently covered with scree material, much of this outcrop has been marked by a series of trenches and pits, many of which date from early pioneer prospecting.

Both the UG2 and Merensky reefs are present at Modikwa. The UG2 Reef occurs as a chromitite layer with an average thickness of approximately 60 centimetres. Three leader chromitites occur above the main seam. Gentle undulations of the UG2 Reef with amplitudes of less than 2 metres are developed across the mine area. Potholes are randomly distributed within the North shaft area but are less abundant in the South shaft area. The Onverwacht Hill area in the southern portion of the mine is characterised by the presence of several large ultramafic pegmatoid intrusions that disrupt, and locally replace, the UG2 Reef.
