    Mimosa Mining Company is operated by Impala Platinum and jointly owned by Sibanye on a 50:50 shareholding agreement following the conclusion of a US$4.3 billion all-cash offer in April 2016, which resulted in Sibanye acquiring all the shares formerly belonging to Aquarius Platinum.

    Mimosa is a shallow, underground mining operation located in the Wedza sub-chamber of the Great Dyke of Zimbabwe. The Wedza sub-chamber is the southernmost of four chambers of the Great Dyke, hosting the economic main sulphide zone from which the PGM and base metals are mined. The orebody is accessed via two shafts, the Wedza shaft and the Mtshingwe Shaft. The Wedza Shaft has been extensively mined; the Mtshingwe Shaft is at the developmental stage.

    Mining takes place less than 200m below surface, utilising the bord-and-pillar mining method. Ore is processed at a concentrator located on site, at the rate of approximately 227,000 tonnes per month. Concentrates are trucked to South Africa for smelting and refining at Impala Platinum’s facilities. Tailings are disposed of at a storage facility on site.

    The Mimosa Mining Company holds a mining lease over an area of 6,594ha and related exclusive mining rights therein for nickel, copper, cobalt, gold, silica, chromite and PGMs.
