Zimbabwe’s emerging Karo platinum operation has taken another significant step towards production after securing a long-term concentrate purchase agreement with Valterra Platinum.
Tharisa has strengthened the development outlook for its Karo Platinum Project in Zimbabwe after its subsidiary, Karo Platinum, signed a binding term sheet with a subsidiary of Valterra Platinum for the purchase of platinum group metals (PGMs) and base-metal concentrate.
The agreement provides an initial five-year offtake arrangement and represents an important commercial milestone for the Karo project as Tharisa advances plans to bring the open-pit operation into production.
The agreement follows the signing of a special mining lease with the Zimbabwean government, providing Karo with the regulatory framework required to progress the project towards development. Production at Karo is currently targeted to begin in 2027.
Major PGM development
Karo Platinum is located on Zimbabwe’s Great Dyke, one of the world’s most prospective regions for platinum group metals. The project is being developed as an open-pit mine and has a mineral reserve of approximately 2.1 million ounces of PGMs, while its broader mineral resource is estimated at 11.2 million ounces.
Tharisa controls approximately 78.8% of Karo Mining Holdings, while the Zimbabwean government holds a 15% interest through Generation Minerals Private Limited. Karo Platinum itself is 85% owned by Karo Mining Holdings.
The new offtake agreement provides Karo with a committed route to market for its future concentrate production, reducing one of the key commercial uncertainties associated with developing a new PGM operation.
For Valterra, the agreement also provides access to additional PGM-bearing concentrate from Zimbabwe, complementing its existing processing and refining capabilities in the southern African region.
Supporting Zimbabwe’s mining ambitions
The Karo development is part of Zimbabwe’s broader drive to expand its mining industry and attract investment into the country’s mineral resources.
PGMs remain strategically important to Zimbabwe, which possesses substantial deposits along the Great Dyke. The development of projects such as Karo has the potential to increase domestic mineral production, generate export revenues and contribute to employment and economic activity.
Tharisa has positioned Karo as a major component of its long-term strategy to establish a diversified PGM production platform alongside its existing mining operations.
The company’s latest agreement with Valterra is therefore more than a commercial sales arrangement: it represents an important step in establishing the downstream pathway required for Karo’s future production.
Path towards 2027 production
With the mining lease and offtake agreement now in place, attention will increasingly turn to the construction and development programme required to bring Karo into production.
The project is expected to produce a concentrate containing PGMs and base metals, which will be supplied under the five-year agreement on terms customary for PGM concentrate purchases.
The agreement also comes at a time when the global PGM sector is undergoing significant structural changes, including supply constraints and increasing attention on the strategic importance of platinum, palladium and related metals.
For Zimbabwe, Karo’s progress could reinforce the country’s position as an increasingly important PGM producer. For Tharisa, the project offers the potential to expand its exposure to PGMs while building on its existing mining expertise.
As development work progresses, the successful commissioning of Karo in 2027 could mark a significant addition to Zimbabwe’s platinum production base and create a new long-term source of PGM concentrate for the regional processing industry.
