Kiniero on-site power plant nears completion

After announcing plans for a merger this month with a rival West African gold miner, Robex remains on track to deliver first gold at its Kiniero mine in Guinea this December, as it looks to complete work on the power plant

Robex and Predictive Discovery Limited (PDI) announced plans to merge on 5 October.

In a 6 October presentation to investors, Robex said that power station concrete works at Kiniero are now complete.

It leaves the power station erection and installation of auxiliary equipment still to finish, as well as the signing of an agreement for the supply, installation and operation of a separate solar PV plant.

The main power supply will come from Hyundai Heavy Industries’ Engine Machinery (HHI-EMD), which signed an agreement with Sycamore Mine Guinea SAU, now a part of Robex, for eight gensets for the Guinea mine and to support further work in the area.

HHI-EMD is supplying eight sets of 4MW class gensets to supply stable electricity in the mine region, with the units shipped in three instalments from May 2025.

Hyundai said at the time of the award that it plans to “further expand the supply of power generation equipment to off-grid mining regions” on the back the order.

It underscores the strength of demand among natural resources companies and the conviction that thermal gensets still provide the most robust source of power supply in remote, off-grid regions.

PDI’s key asset is the Bankan project in Guinea, which is advancing towards a final investment decision in 2026 and is currently contemplating its power supply options.

This will also likely incorporate a hybrid model, but built around a thermal power source, with the main source of power generated through a heavy fuel oil (HFO) plant in combination with a solar farm, the company noted in a recent feasibility study.

It again highlights the continued pull of HFO power plants as a dependable source of electricity for critical and remote mining and industrial applications in West Africa.

As well as the Kiniero mine, Robex also operates the producing Nampala gold mine in Mali.
