Tharisa Mine begins phased underground expansion to enhance efficiency

Tharisa, dual-listed on the Johannesburg and London stock exchanges, is transitioning the Tharisa Mine from a large-scale open pit to underground mining

This natural progression will sustainably access the mine’s multigenerational mineral resource base while enhancing operational efficiency, environmental stewardship, and long-term value creation.

The mine’s mineral reserves extend beyond the open pit shell, presenting a high-confidence, low-geological-risk opportunity to sustain operations for over 50 years. Existing processing facilities have a capacity of 5.6 Mtpa of run-of-mine (ROM), ensuring both production scalability and operational flexibility. Open pit operations are scheduled to be depleted by FY2035.

From 2031, underground ore from the West Mine (Apollo Complex) and East Mine (Orion Complex) will supplement production. Both complexes, developed sequentially, are designed to mine 255 ktpm each at steady state, combining for 510 ktpm, capped by plant feed capacity.

This underground expansion will maintain current PGM and chrome concentrate output, with opportunities for growth through smarter mining and reduced dilution. The project will operate under a mining contractor model, with transitional capital of US$547 million over ten years and peak funding of US$173 million, financed via internal cash and external funding lines.

Phoevos Pouroulis, CEO of Tharisa, said: “The underground project is the natural progression for our operations and has been established to increase life-of-mine development, enhance operational efficiencies, while maintaining our world-class standards of health, safety, environmental stewardship, and further enhancing our track record of long-term value creation.”

He added: “Our shallow ore body enables on-reef mechanised development, delivering cleaner ROM and significantly reducing waste, capital intensity, and environmental impact. The phased approach to portal development enables early access to reef with the bord-and-pillar design supporting safe, cost-effective ramp-up and long-term operational efficiency. As we continue to innovate with purpose, we are setting the benchmark for multiple generations to come.”

South Africa’s Condra has received “multiple orders” to manufacture cranes, hoists and other lifting equipment for mine expansion projects in Sierra Leone, Tanzania and Namibia

The orders were placed by consulting firms in Canada and Australia, but non-disclosure agreements mean neither the customers nor the mines can be named.

The value was also not disclosed by Condra, which will execute the orders at its Johannesburg factory.

In a statement, Condra said the cranes will work in general workshop and feeder-line maintenance applications, with capacities ranging from two to eighteen tons.

Sierra Leone’s order comprises one long-reach jib crane, three single-girder overhead cranes and a portal crane, while Tanzanian mines will receive two double-girder cranes, a single-girder machine, one portal crane and a long-reach jib crane.

Six Titan hoists, among them several fitted with articulated carriages to negotiate curved girder tracks, will go to Namibia along with two portal cranes, a long-reach jib crane, two single-girder cranes and a double-girder machine. Fifteen chain hoists and blocks will also be shipped to Namibia.

Condra’s Titan hoist range is versatile, comprising the Compact Series with capacities to 32 tons, and the SH (Short-Headroom) Series with capacities to 18 tons. All models are variants of the veteran K-Series hoists, but refined to offer a more compact profile with reduced overall dimensions.

Among the cranes included in the international orders are several equipped with high-lift K-Series hoists, in one instance to a height of 40 metres. These hoists have a proven record in high-lift applications. The company’s installed base includes hoists with controlled lifts as high as 150 metres.

A Condra spokesman said there had been “close cooperation” with the consultants to ensure that agreed prices could remain competitive without compromising the robust reliability required for harsh operating conditions.

Overall lifetime cost will remain lower than cranes offered by rival firms, said the spokesman, while inspection and testing will take place at defined stages during manufacture to ensure compliance with international quality control, safety and lifting equipment standards.

Manufacturing is now underway at the company’s Germiston factory, with delivery to be carried out by road. A number of crane girders will be spliced to allow packing in standard 12-metre containers.

Shipping dates will be staggered to meet project timetables, with delivery scheduled for late 2025 through to mid-2026.

Technicians from Condra will then manage installation and commissioning in Sierra Leone, while local agents will carry out this work in Tanzania and Namibia.

Early works at Kokoseb (Image source: Wia Gold)

Australia’s Wia Gold Limited has outlined power and infrastructure plans for its proposed Kokoseb gold mine in Namibia, citing the project’s “outstanding potential” following completion of a scoping study
 
The energy mix looks to tap into the national power grid, with additional back-up support from on-site diesel generators (gensets).
 
Galetech Australia was engaged to provide an assessment of options for power supply to the project.
 
Access to the site, which lies north west of the capital Windhoek, will be from the unsealed C36 road between Omaruru to the east, and Uis to the west.
 
The proposed site access road will consist of a new all-weather surface, approximately 12.7 km long to enable access to both the accommodation village and the mine site and associated plant and equipment.
 
The overall power requirement for the Kokoseb project is an average continual operational demand of approximately 31MW, Wia Gold reported.
 
The Namibian grid in the project area is centred around the Omburu substation located close to Omaruru, which is a major hub connected at 330 kV to Angola in the north and 220 kV to Windhoek and Swakopmund.
 
Local supply from Omburu includes a 66 kV connection to Uis that runs through the project exploration lease as well as 66 kV supplies to Karabib and the nearby Navachab gold mine as well as other regional centres.
 
Wia Gold reported that a workshop with state utility, NamPower, identified that connecting to the existing Omburu–Uis 66 kV line would exceed the allowable 10% voltage drop, exceed existing line capacity, and push conductor temperatures beyond their rating in summer, ruling it out.
 
As such, a new 95 km 66 kV spur from Omburu substation was therefore selected to provide sufficient capacity to supply the project, Wia Gold said.
 
On completion of the construction of the connection the asset would be handed over to NamPower for ongoing operation.
 
“Power supply from the Namibian grid is cost effective compared to all other options, with an average power cost for the project over life of mine of approximately US$0.117/kWh.” Wia Gold noted.
 
At site, the voltage would be stepped down to 22 kV for distribution to the various load centres.
 
“Local diesel generation will provide back-up power for the project,” the Wia Gold statement added.
 
As part of the process for accessing power from the Namibian grid, the mining company has already submitted an application to NamPower, which is now undertaking a technical assessment to outline connection requirements.
 
Wia Gold is also continuing its own studies with a view to securing financing for the project in the latter half of 2026.
 
The company holds multiple other mining projects across the continent, mainly in West Africa and Southern Africa.
