Is it a good time for mining companies to expand major projects in developing countries?
Tharisa has reached its 2026 production goals for platinum group metals and chrome as it advances the development of its Karo Platinum project in Zimbabwe. The company secured funding through a $300 million bond issuance to support infrastructure construction.
Why it matters
The capital raise provides the financial runway necessary to accelerate the Karo project following the securing of a 25-year mining lease. This move stabilizes project tenure and fiscal outlook for operators navigating large-scale extractive development.
Tharisa produced 153,700oz of platinum group metals and 1.56 million tonnes of chrome concentrate during FY2026. The firm also secured a 23,903-hectare mining lease at the Great Dyke, supported by a $300 million bond issue that builds on a previous $240 million investment.
The players
Tharisa
A mining group focused on the extraction of platinum group metals and chrome concentrate.
Valterra Platinum
An offtake partner that signed a five-year concentrate agreement with Tharisa in August 2026.
Zimbabwean Government
The national authority that granted a 25-year special mining lease to Tharisa for the Great Dyke site.
The details
The bond issuance allows Tharisa to scale operations at the Karo Platinum site, where the company holds a 25-year special mining lease. To stabilize future revenue, the company also signed a five-year offtake agreement with Valterra Platinum. Development is currently focused on ore mining, with the firm targeting first ore delivery to the mill by the fourth quarter of 2027.
Timeline
August 2026: Signed 25-year mining lease and five-year offtake agreement.
September 2026: Issued $300 million in bonds to institutional investors.
October 2026: Ore mining at the Karo project is scheduled to commence.
Q1 2027: Mechanical and pipeline installation phase begins.
Q4 2027: Targeted first ore to the mill at the Karo project.
Market Landscape
The 25-year special mining lease granted by the Zimbabwean government serves as a foundational precedent for project longevity in the region. This agreement follows the industry trend of securing long-term tenure as a prerequisite for institutional-grade debt financing.
Operators should monitor the timeline for ore delivery as a benchmark for capital expenditure efficiency in large-scale mining. The shift toward long-term offtake agreements like the one with Valterra Platinum signals a preference for cash flow stability over spot market exposure.
The takeaway
Large-scale expansion requires a balance between institutional debt and secure regulatory tenure. Operators should track the conversion rate of mill-ready ore as a key performance indicator in project development schedules.
