A restart of a major gold mining project in South Africa is a rare event, and Sibanye-Stillwater has now signalled that it plans one. News24 carried the story under the headline “A major SA gold mine restart is rare. Sibanye plans one”, and reporting from early September 2026 points to the Burnstone gold project in Mpumalanga as the restart in question. The original News24 report is behind a paywall, so the detail below comes from other reporting on the same project.
What is known about Burnstone
Burnstone is not a brand-new mine. According to Miningmx’s June 2025 report, the project in Mpumalanga was halted in 2021 as Sibanye sought to conserve cash during a sharp fall in platinum group metal prices. The project was valued at about R5 billion, with roughly R4 billion already spent before the halt and about R1 billion in outstanding project capital, plus some ramp-up capital. Chief executive Neal Froneman described it at the time as shallow, of decent grade and long life, and said it was “not a high-cost operation.”
On the latest numbers, Mining Focus Africa reports that Sibanye-Stillwater has approved the project, which is expected to produce about 130,000 ounces of gold a year over a projected 25 years, with reserves of 2.7 million ounces. Earlier reporting had put output at about 120,000 ounces a year over 20 years, so the plan has evolved since 2025. Reporting also said Sibanye would allocate funds to advance the project in 2026, though the sources opened do not agree on the exact amount, and no total capital cost for the restart is confirmed here.
What it could mean for small businesses
For small- and medium-sized enterprises that supply the mining value chain, from transport firms to catering services, a restart is a potential new customer. The timing matters, though: contracts are typically awarded during the construction and development phase, and a project of this kind can spend one to several years in shaft development and ramp-up before reaching full production employment. Local contractors and suppliers are therefore more likely to see a gradual build-up of work than an immediate hiring wave, a timeline worth factoring into any small business weighing whether to gear up in anticipation.
South African gold projects also carry the cost of operating in some of the deepest and most technically demanding underground conditions in the world, which is part of why capital has flowed to other jurisdictions in recent years. A restart of a project that was already largely built, and that management describes as shallow, is a different proposition from developing a new deep mine from scratch. Whether Burnstone proves to be a successful outlier depends on how well Sibanye executes, and on a gold price that remains volatile.
In short, the Sibanye plan is a rare note of optimism for a sector that has been in retreat. The sources agree that the project is a restart rather than a new mine, but readers should check the company’s own announcements for the approved capital budget and the first-ore timeline.
