Resources & Reserves

Mimosa

Mimosa is located in Zimbabwe, east of Bulawayo in the Wedza Complex of the Great Dyke. PGM Mineral Resources at Mimosa are located in four erosionally isolated and fault-bounded blocks, consisting from north to south of: the North Hill, South Hill, the Mtshingwe and Far South Hill areas. The Mimosa mine is located in the eastern part of the South Hill block. The north-north-east trending layered igneous rocks within the layering dip from the sides towards the axis of the intrusion and flatten out near the centre.

The platinum-bearing Main Sulphide Zone (MSZ) lies about 10m below the base of the mafic sequence and is a continuous layer between 2 and 3m thick that forms an elongated basin. The MSZ at Mimosa has a well-defined grade profile.
