South African mining has entered 2026 on a high it has not seen in years. Platinum-group-metal prices have surged on tightening supply, dragging the entire complex up with them — PGM sales rose more than 110% year on year in early 2026 — and gold’s record run has added momentum, re-rating the JSE’s mining index and pushing the sector’s projected annual mineral sales toward the trillion-rand mark for the first time. After four consecutive quarters of decline through 2025, the recovery is real.

But the strength is narrower than the headline suggests, and this is exactly where honest modelling matters. Revenue is being driven far more by price than by volume — PGM sales rose over 110% while production grew around 10% — which means the upturn rests on a commodity cycle that can reverse. Costs are climbing: primary platinum all-in sustaining cost is forecast up roughly 7.7% in 2026, pressured by inflation, energy, and the geological reality of deeper, lower-grade ore. A decade of under-investment in mine recapitalisation is now feeding into future production risk, and Transnet logistics and energy constraints continue to cap what the sector can move and produce.

For anyone allocating capital across a long-life asset, that combination — a price-driven boom over a cost-pressured, volume-constrained base — is precisely the environment in which a model must tell the truth. Scenario testing against a price correction, honest life-of-mine economics, and properly provisioned rehabilitation and closure liabilities are what separate a business that is genuinely creating value from one that is simply riding a cycle.
