Tharisa PLC, a South Africa-listed mining firm, will enter Zimbabwe’s Great Dyke region, which holds the world’s second-largest platinum reserves after South Africa.
The move follows an 85% stake in Karo Mining Holdings, owner of the Karo Platinum Project. Zimbabwe’s government holds the remaining 15%, creating a joint venture targeting production within two years.
Projected output and financials
The Karo Platinum Project should produce at least 150,000 ounces of platinum group metals annually once operational. Initial reserves stand at 35 million tons, averaging 2.31 grams per ton, equating to about 2.6 million ounces over the mine’s 20-year life.
The first phase requires $250 million, with total costs reaching $310 million. At current prices, the project’s net present value is $770 million, though favorable conditions could push it near $1 billion.
Funding will include export-import finance, political and commercial guarantees, and senior debt. Tharisa will cover its equity portion through internal cash flow instead of upfront capital, a choice that has drawn skepticism. Senior debt holders would be repaid first in a default, while subordinated creditors would rank lower.
A test for Zimbabwe’s capital markets
Karo Mining Holdings intends to issue a $50 million corporate bond on the Victoria Falls Stock Exchange, a dollar-denominated bourse launched in 2020. Success would make it the largest capital raise on the exchange, which currently lists only four companies.
The VFEX offers tax exemptions on capital gains and allows fund repatriation to attract foreign investment. Its limited history has raised doubts about handling large, long-term financing. The bond issuance will test whether the exchange can support such ambitions.

Cash flow will stay negative until production starts, creating uncertainty about meeting debt obligations. Low equity stakes can increase the risk of sponsors abandoning struggling projects, which may affect investor confidence.
Zimbabwe’s PGM sector has attracted interest before. Impala Platinum Holdings, a major producer, has said the country’s poor reputation works in its favor, letting its local unit outperform others in its portfolio. The Karo project, valued at $250–310 million, could signal more opportunities in the sector.
For Tharisa, the venture marks significant growth. The company also mines chrome and currently produces 200,000 ounces of PGMs per year. Karo’s full output would double that figure. Operations span South Africa, Zimbabwe, and Cyprus, with subsidiaries covering mining, processing, logistics, and equipment manufacturing.
The bond timing matches Zimbabwe’s efforts to trade debt on the VFEX, though the exchange’s capacity remains unproven. The project is a high-stakes bet that could strengthen Zimbabwe’s PGM position or reveal flaws in its financial system.
Mining stocks, including Tharisa’s, have been volatile, reflecting market conditions and sentiment about growth plans. The company’s focus on both PGMs and chrome makes it unusual, with its Bushveld Complex assets holding over 70% of global platinum and chrome resources.
Success depends on execution, stable funding, and commodity prices. If achieved, the two-year timeline from development to production would be unusually fast for the industry.
Major producers have faced similar risks when expanding into new markets, where financial structures and local conditions can shape outcomes.
