Tharisa is building the 194,000 ounce per year Karo PGM mine at a cost of $391 million on Zimbabwe's Great Dyke, about 100 km (62 miles) south-west of the capital Harare. The mine, which is close to Impala Platinum's Zimplats operations, was due to be commissioned by July 2024.

"Given the current PGM basket price weakness and uncertain global economic outlook, we have taken the measured decision to extend the Karo Platinum timeline out to commissioning by June 2025, with the opportunity to accelerate the timeline as markets become more favourable," South Africa-based Tharisa said.

The prices of PGMs, mainly used to make catalytic converters which help control emissions in vehicle engines, have declined rapidly over the past year.

Tharisa realised an average PGM basket price of $1,893 per ounce in the year ended Sept.30, 26% lower than the average price of $2,564 per ounce it received during the same period in 2022.

PGM major Sibanye Stillwater's CEO Neal Froneman has warned of "significant restructuring" which could result in shaft closures and job losses in the platinum industry due to the current low metal prices.
