Sibanye-Stillwater job cuts: Here’s what NUM is proposing instead of mine closures and retrenchments

The National Union of Mineworkers (NUM) in Rustenburg, North West, has called on the government to consider small-scale mining companies as alternatives to large-scale mining operations closing down due to declining production. This proposal comes as Sibanye-Stillwater, a major mining company, initiates section 189A consultations for the restructuring of the Kwezi shaft at its South African platinum group metals (PGM) operations in Rustenburg.

NUM's Rustenburg Regional Chairperson, July Radibe, expressed concern over the rising number of mine closures, urging the government to explore the potential of small-scale mining companies to take over operations.

Sibanye-Stillwater revealed that the Kwezi shaft, which had reported losses of approximately R208 million in 2024 and R91 million in 2025, is nearing the end of its economic life. Despite a positive impact from stronger PGM prices in the first half of 2026, the company predicts returning to losses in the second half of 2026 due to declining production. The restructuring of the Kwezi shaft will affect over 1,000 employees and 333 contractor employees.

NUM hopes that Sibanye-Stillwater will consider alternative vacant positions within the group before resorting to retrenchments. The union believes that the international status of the company may facilitate the exploration of alternative job options for affected employees. Sibanye-Stillwater acknowledged the uncertainty surrounding consultation processes and emphasized its commitment to engaging constructively with employees and their families throughout the process.
