Tharisa (THS ), the platinum group metals and chrome miner with interests in Southern Affrica, has entered into a binding arrangement for the sale of PGM concentrate to Rustenburg Platinum Mines, a subsidiary of Valterra Platinum.
From 1 January 2027, under a multi-year agreement, Valterra Platinum will purchase 50% of the PGM concentrate produced by the Tharisa mine on comparable terms, replacing Sibanye-Stillwater Limited as an offtake partner.
Northam Platinum Limited retains its existing offtake arrangement for the remaining 50% of the Tharisa Mine's PGM concentrate production.
In addition, Tharisa and Valterra Platinum are collaborating to explore opportunities for fine chrome recovery and beneficiation at Valterra Platinum.
The collaboration explores the use of Tharisa's Vulcan X technology to recover fine chrome.
The expanded sale of concentrate relationship and chrome collaboration form part of the broader cooperation between Tharisa and Valterra Platinum announced on 27 August 2026, which included Valterra Platinum contracting as the concentrate purchase partner for the Karo Platinum project in Zimbabwe.
'The agreement with Valterra Platinum to purchase 50% of the Tharisa Mine's PGM concentrate from 1 January 2027, alongside Northam Platinum's continued offtake, provides certainty for our PGM production,” said Phoevos Pouroulis, chief executive of Tharisa.
“Equally important is our collaboration on chrome recovery and beneficiation. With the pilot plant complete and testing under way, we are taking a tangible step towards deploying our proprietary fine chrome recovery technology. Together partnering with Valterra Platinum as concentrate purchase partner for Karo Platinum, these developments demonstrate the breadth and strategic value of our cooperation. By combining Tharisa's technology and operational capabilities with Valterra Platinum's leading downstream processing expertise, we are well positioned to improve recoveries and deliver sustainable value for all stakeholders.'

Good to see the relationship with Valterra strengthening. It will be one of Tharisa’s key partnerships in the years ahead, as the company moves through a transformative period in which its output capacity should increase dramatically. There’s still a lot to do, but the direction of travel is clear.
