Tharisa prices $300m Nordic bond to complete Zimbabwe's Karo Platinum mine

Tharisa priced a $300m five-year senior secured bond on 11 September 2026, issued through its wholly owned subsidiary Arxo Finance at 98% of face value with a semi-annual coupon of 11.00% a year. The offering was oversubscribed, drawing demand from institutional investors across Europe, the UK, the Middle East, North America and Asia, and proceeds are earmarked primarily to complete development of the Karo Platinum project on Zimbabwe's Great Dyke.

Funding the final stretch

Karo, a joint development between Tharisa and Zimbabwean partners, has a total projected development cost of about $545m and probable reserves of 35.5 million tonnes containing roughly 2.5 million ounces of platinum group metals and gold. Settlement of the new bond was expected on 24 September 2026, with proceeds held in escrow until conditions were satisfied, and first ore to the mill targeted for the fourth quarter of the 2027 calendar year. Mobilisation of the project's mining contractor has been completed, open-pit waste stripping is under way, and long-lead equipment for the concentrator has been delivered and is being installed.

Zimbabwe's stake

Zimbabwe granted Karo Platinum a 25-year special mining lease over nearly 24,000 hectares of the Great Dyke, and the state holds a direct 15% interest in the project, with an option to increase that to 26%, reflecting the country's push for greater equity participation in new mining developments. The project has already attracted about $240m of investment, with plans for close to $1bn in total first-phase spending.

Why the bond structure matters

A Nordic-style bond priced at an 11% coupon reflects both the strong institutional appetite for platinum-linked project financing at current PGM prices and the country-risk premium international lenders still attach to Zimbabwe. For Tharisa, a dual-listed South African group better known for its chrome and PGM co-production, successfully placing a project bond of this size signals growing investor comfort with Zimbabwean mining risk when projects carry credible construction progress and government backing.

The strong institutional demand for the bond also suggests international debt investors are becoming more comfortable pricing Zimbabwean mining risk on its own project-specific merits, rather than applying a blanket country discount, provided a project shows credible construction progress and a clear path to production.
