SIBANYE STILLWATER LIMITED - Sibanye-Stillwater enters into Section 189A consultations regarding the proposed restructuring of Kwezi shaft at its SA PGM operations
What this filing means
A formal labour-restructuring process that confirms one shaft has run out of economic life. Sibanye-Stillwater is entering Section 189A consultations over Kwezi shaft, a mature Rustenburg PGM operation that lost R208 million in 2024 and R91 million in 2025, and is forecast to return to losses in H2 2026 despite the strong PGM price environment. The Kwezi Shallows life-extension project was blocked by stakeholder objections and approval delays, leaving no alternative reserves. The restructuring could affect roughly 781 employees and 333 contractors, though Kwezi produced less than 3% of SA PGM output in H1 2026.
Sibanye is formally starting the process to restructure a shaft that has simply run out of mineable ground. The company tried to extend its life with a new project, but objections and permit delays blocked it. The shaft is losing money even while PGM prices are strong, which tells you the problem is structural, not just a bad price cycle. The good news is that this shaft is a very small part of the group's total production.
Bull case
- Kwezi represented less than 3% of total managed and attributable SA PGM production in H1 2026, limiting the potential portfolio-level production impact of its proposed restructuring.
Bear case
- The blockage of the only named life-extension project leaves Kwezi without a secured reserve replacement pathway, and the unresolved approval delays suggest no near-term resolution.
- Kwezi is forecast to return to losses in H2 2026 despite the strong PGM price tailwind that drove record group earnings, signalling a structurally uneconomic shaft rather than a cyclical issue.
- Mining has reached the limits of the approved mining license area and no alternative reserves have been secured, leaving Kwezi with a hard geological and permit-constrained endpoint.
- The proposed restructuring could affect approximately 781 employees and 333 contractors, introducing material retrenchment cost, labour-relations friction and execution risk during the Section 189A process.

SENS-AI conclusion
A negative operational signal, but one that is contained in scale. The filing confirms Kwezi is structurally uneconomic — losing money in a strong PGM price environment, with no alternative reserves after the Shallows project was blocked. The restructuring introduces retrenchment cost and labour-relations risk, and the regulatory/community opposition that killed the life-extension project is a portfolio-level caution. The offset is that Kwezi is less than 3% of SA PGM production, so the direct earnings impact is limited. So what: the market still needs to see the restructuring cost quantified and whether the Section 189A process triggers wider labour friction across the Rustenburg complex.
The next disclosure should quantify the restructuring provision and confirm whether the Section 189A process stays confined to Kwezi.
Evidence from the filing
The blockage of the only named life-extension project leaves Kwezi without a secured reserve replacement pathway, and the unresolved approval delays suggest no near-term resolution.
“A recently proposed Kwezi Shallows project that had an opportunity to access available shallow up-dip mineral resources was expected to add reserves and support future production; however, stakeholder objections, appeals and delays in required approvals have prevented the project from progressing as planned”
Kwezi is forecast to return to losses in H2 2026 despite the strong PGM price tailwind that drove record group earnings, signalling a structurally uneconomic shaft rather than a cyclical issue.
“Kwezi is forecast to return to losses during the second half of 2026 as production declines”
Mining has reached the limits of the approved mining license area and no alternative reserves have been secured, leaving Kwezi with a hard geological and permit-constrained endpoint.
“Kwezi is a mature underground PGM shaft within the Rustenburg operation where mining has reached the limits of the approved mining license area. As such, and in line with expectations, the shaft is approaching the end of its economic life”
The proposed restructuring could affect approximately 781 employees and 333 contractors, introducing material retrenchment cost, labour-relations friction and execution risk during the Section 189A process.
“The proposed restructuring could potentially affect approximately 781 employees and 333 contractor employees”
Kwezi represented less than 3% of total managed and attributable SA PGM production in H1 2026, limiting the potential portfolio-level production impact of its proposed restructuring.
“In H1 2026, Kwezi produced 20,658 4E ounces, representing less than 3% of total managed and attributable SA PGM production of 734,645 4E ounces for the period”
