A project that aims to develop Zimbabwe’s biggest platinum mine has cleared a significant hurdle, with the African Export-Import Bank completing a due diligence study allowing it to proceed with a $500-million syndicated funding programme.

While some work has started on the mine, with $100-million spent to date including exploration costs, a significant amount of investment will now be needed if Great Dyke Investments, owned by Russia’s Vi Holding and Zimbabwean investors, is to complete the $2-billion project.

“The project funding structure envisages participation of various types of equity investors as well as lenders,” Alex Ivanov, GDI’s chief executive officer, said in response to emailed questions. “The specific stake to be acquired by potential investors would largely depend on their overall appetite for the project.”

Ivanov confirmed the completion of the due diligence program and said he expects the funding to be in place by year end. Humphrey Nwogo, Afreximbank’s southern African chief operating officer declined to comment, citing client confidentiality.

The so-called Darwendale project, which lies 65 kilometers (40 miles) from the capital Harare, is central to the Zimbabwean government’s plans to revive its stagnant economy. The country has the world’s third-biggest platinum reserves after South Africa and Russia.

Still, the country is struggling to attract foreign investment. It’s unable to pay its debt to multilateral organizations such as the World Bank and has been criticized by potential lenders for its poor economic management and human rights abuses.

Even so, the activity at the mine site is a rare sign of potential investment in a country that seen’s its currency collapse and inflation surge to more than 700%.

On a recent visit some workers were seen drilling for ore samples while others constructed roads needed for earthmoving equipment. Training of crews to operate that equipment was also taking place.

Commissioning of the mine could begin in 2023 if funding is forthcoming, Ivanov said. When complete it is expected to produce 860 000 ounces of platinum group metals and gold a year.

If successful, GDI will join South African companies Impala Platinum Holdings Ltd. and Anglo American Platinum Corp. in producing the precious metal in the company. Karo Mining Holdings, a Cypriot company, is also planning to develop a large platinum mine in Zimbabwe.
