Redpath Africa at Mogalakwena Sandsloot: underground transition notes for mine engineers
Reviewed by Tom Sullivan

First reported on International Mining – News
30 Second Briefing
Redpath Africa is advancing underground mine development beneath Anglo American Platinum’s Mogalakwena Sandsloot open pit in Limpopo, South Africa, executing complex lateral development to transition the operation towards a large-scale underground layout. The contractor is driving access and infrastructure beneath the existing pit shell, managing geotechnical interaction with the active open pit and associated ground control, ventilation and water management constraints. The project is also being used to train South African crews in mechanised underground development, building local skills in jumbo drilling, ground support installation and decline logistics.
Technical Brief
- The project involves developing an underground mine beneath an existing open pit.
- The project explicitly targets transfer of mechanised underground development skills into the local mining workforce.
- Ventilation and water handling systems are being integrated early to maintain safe working conditions during development.
Our Take
Redpath Africa Limited’s work at Mogalakwena Sandsloot follows its recent shaft equipping at Northam Platinum’s Zondereinde Western Expansion, signalling that it is becoming a go‑to contractor for deep and complex underground scopes in South Africa’s platinum belt.
The related coverage showing Redpath Africa broadening from raiseboring into full-scope development and contract mining suggests that its role at Mogalakwena Sandsloot is likely part of a deliberate push to secure longer-duration, integrated underground work across sub‑Saharan Africa.
