Platinum drags down SA mining production index - Engineering News

AI desk brief

South Africa’s mining output index fell 5.5% in the May-July 2026 period versus February-April, with platinum group metals doing the heavy lifting on the downside. PGMs account for 27% of the index and dropped 14.3%, pushing the series lower after they had been running at a three-month high earlier in the year.

Coal was broadly stable in the latest period, while copper rose 12.3% but remains a small contributor. Gold and iron ore are also cited among the main components of the index, but the article’s main tradeable signal is a notable near-term supply slowdown in PGMs from South Africa.
