    Mimosa Mining Company is jointly owned by Sibanye-Stillwater and Impala Platinum Holding Limited (Implats) on a 50:50 basis. Our share in Mimosa, which is operated by Implats, was acquired following the conclusion of a US$4.3 billion transaction in April 2016, in terms of which Sibanye acquired Aquarius Platinum and thus its 50% holding in Mimosa.

    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 MSZ 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.

    Bord and pillar mining takes place less than 200m below surface. Ore is processed at a concentrator located on site, at a rate of approximately 227,000 tonnes per month. Concentrate is trucked to South Africa for smelting and refining at Implats’ 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.
