Overview

Kroondal is situated in the Magisterial District of Rustenburg near the town of Rustenburg, approximately 120km north-west of Johannesburg and about 120km west of Pretoria (Tshwane) in the North West province of South Africa.

Kroondal consists of established shallow, mechanised PGM mines in the Western Limb of the BC. Currently Kroondal consists of five operating shafts and one shaft under care and maintenance. The UG2 Reef is currently being mined at Kroondal. The deposit is accessed from surface using decline systems and mined via bord and pillar method. Mining takes place at depths between 250m and 550m below surface.

There are two concentrator processing plants (K1 and K2) processing the run-of-mine (ROM) at Kroondal operations and there is spare processing capacity at a third plant, which is currently under care and maintenance (Marikana plant).

While Sibanye-Stillwater purchased all of the Aquarius Platinum Ltd (Aquarius) assets, the MR is registered under AAP and therefore excluded. The Kroondal Extension is mined on royalty basis to AAP by the Sibanye-Stillwater with exclusive MR from AAP.

All legal aspects and tenure are in order.

In 2017, Attributable production of 4E PGM at Kroondal was higher at 241,225oz, another record performance since it started mining in 2001 and 35% higher than in 2016.
