History.
In 2012, Gold Fields Limited unbundled its subsidiary, GFI Mining South Africa Proprietary Limited (“GFIMSA”), which was then renamed Sibanye Gold Limited (“Sibanye Gold”), and consisted of the KDC (formerly Kloof) and Beatrix mines, as well as an array of support service entities in South Africa. "Gold Fields stockholders were given one share in Sibanye for each of their Gold Fields shares." The three South African mines transferred from Gold Fields to Sibanye are:
In April 2016 company acquired Aquarius Platinum.
On 30 August 2017, Sibanye Gold Limited began trading as Sibanye-Stillwater and reorganized its operations by region – Southern Africa and the United States.
According to their latest annual report, the company produced 2.2 million ounces of PGM and 0.9 million ounces of gold and sales were approximately $5 billion (2019). In June 2019, Sibanye-Stillwater acquired Lonmin Plc, London, UK, a top tier PGM producer. The enlarged group is the world’s largest primary producer of platinum and rhodium, one of the largest producer of palladium and the leading recycler and processor of spent PGM catalytic converter materials.
The operations employ 84,521 people, mostly in South Africa (2019). Thus, Sibanye-Stillwater is one of the top four private sector employers in South Africa and the largest industrial employer in the state of Montana.  
2018 Incident.
In January 2018, a power outage caused by poor weather resulted in nearly 1000 miners being trapped underground. This occurred at the Beatrix gold mine near Welkom, South Africa. Some of the trapped miners were rescued the day of the incident, and the remaining 955 were rescued after around 30 hours when power was restored to one of the lifts. The incident has resulted in pressure from labour unions, including the National Union of Metalworkers of South Africa, for mine management to address safety concerns before it can reopen.
