New rigs aim to cut mine development times in half.
Master Drilling is moving to reshape underground mining with technology built for continuous, round-the-clock operations. The Johannesburg Stock Exchange-listed company says the system will lower costs and boost efficiency, even in narrow reef conditions.
Director Koos Jordaan told investors the company is building on years of mechanised excavation. Its rigs can now perform shaft sinking, tunneling, and reef boring with more speed and precision.
At the same time, Master Drilling reported a 399 percent rise in half-year after-tax profit to $18.1 million, reflecting demand for its solutions.
The presentation repeated three words — “continuous rock excavation” — to highlight the company’s direction. Jordaan said the goal is to move away from stop-start mining toward systems that can run without interruption.
Remote systems improve safety and speed
Automation lies at the core of Master Drilling’s strategy. Its monitoring system already tracks about 75,000 underground workers daily.
The data gives mines a clearer picture of activity and improves safety. Jordaan added that the company is advancing selective mining methods to deliver higher ore grades.
Robotics are also in testing for drilling and material handling. Digital platforms now allow exploration data to be processed and shared faster.
Master Drilling operates in 28 countries across five continents, with raiseboring remaining its largest business line.
New rigs such as the Bluebot and RD6 DC are already in service. Trials are also underway on slim robotic drilling rigs and new shaft sinking systems.
“The aim is quicker underground access that lowers risk while speeding up development,” Jordaan said.
New rigs set for projects ahead
The company has secured a contract to deploy its mobile tunnel borer at African Rainbow Minerals’ Bokoni platinum mine in Limpopo in 2026. Unlike traditional tunnel boring machines, it does not need large-scale excavation before work begins. Its modular design makes it easier to assemble and transport, cutting both time and manpower.
Master Drilling is also testing narrow reef cutters. These rigs could halve mine development time while keeping output steady. Jordaan said they are designed to raise ore quality and allow continuous mining without blasting.
Safety tools are being rolled out alongside the rigs. Collision-prevention cameras are under test on locomotives. Winch proximity systems are being installed at stope sites. Shift clearance tools are also being developed to shorten re-entry delays.
“We’re confident about the progress,” Jordaan said. “This technology lets us reach deeper, develop faster, and keep people safe.”
