Phoevos Pouroulis, CEO of Tharisa, commented:

"The first quarter of the financial year was another safe quarter operationally, with production reflecting planned mine volumes and the seasonal operating environment. While output was softer at the start of the year, leading indicators across the business are trending positively, particularly in mining, where recoveries have begun to improve following weather and sequencing-related impacts experienced during the quarter.

Underground development continues to progress in line with our strategic plans, supporting the next phase of operational flexibility and sustainability. At Karo, development remains aligned with capital availability, with Tharisa providing additional funding support to maintain momentum on the project timeline.

PGM prices were robust during the quarter, underpinned by supportive market fundamentals, and we were able to deliver production into this pricing environment. We remain constructive on the PGM price outlook and expect current price levels, and potentially higher levels, to persist in the months ahead. "

Market Update

‒      Platinum fundamentals remain in deficit for the third consecutive year. Legislative  changes in the European Union regarding the 2035 ban on combustion-engine vehicles coupled with tariff uncertainty and rising investment appetite for the precious metals cluster meant PGM prices rose sharply over the past quarter and continue to hold firm. Chrome prices remain stable and will likely remain range bound until after the Chinese New Year. Chinese stainless steel production increased during 2025 compared with 2024 and is expected to increase by approximately 3% into 2026.
