Teleoperating a Copper Mine From 150 Kilometres
Marcobre has deployed a Huawei private 5G network at Mina Justa in Peru's Ica region, supporting equipment teleoperation from more than 150 kilometres away in what is described as the country's first 5G mining deployment.
Marcobre, the copper subsidiary of Minsur, has commissioned a private 5G network supplied by Huawei at the Mina Justa mine in the Ica region of Peru, described as the first 5G mining deployment in the country. The network supports teleoperation of equipment from more than 150 kilometres away, alongside real-time data processing, automated process control, AI platform integration and cloud connectivity. Targeted gains include improved precision in drilling and blasting and predictive maintenance. Juan Luis Kruger, chief executive of Minsur, described the deployment as the beginning of a long-term strategy to incorporate higher levels of connectivity and new technologies.
Mining is where private cellular has the least to prove, and the reason is the distance figure rather than the technology. Teleoperating a loader or a drill rig from 150 kilometres away is not primarily a bandwidth problem — video at working quality is a few megabits — it is a latency and reliability problem, and the operator's ability to work safely depends on the link behaving the same way on the thousandth cycle as the first. Wi-Fi in an open pit, with its roaming behaviour between access points and its unlicensed interference, has never been a comfortable foundation for that; a licensed or dedicated-spectrum network with deterministic handover is.
The 150 kilometres is also the business case, and it is a different one from the efficiency arguments usually attached to industrial 5G. Mines are in places people do not want to live. Moving operators from the pit to a control room in a city changes the labour market the mine recruits from, removes rosters of fly-in shifts, and takes people out of the most hazardous positions on site. That is a far larger economic lever than a percentage improvement in drilling precision, and it is the reason mining has moved faster on this than manufacturing has.
For industrial operators elsewhere, the transferable lesson is about what justifies the network rather than the network itself. A private 5G deployment is expensive and operationally demanding: spectrum, core, radios, SIM management, integration with existing systems, and a skill set most plants do not have. It pays when there is an application that genuinely cannot be delivered another way, and teleoperation over a hundred kilometres is unambiguously that. Where the application is telemetry from fixed sensors, the honest comparison is against a well-engineered Wi-Fi or LPWAN network, and the answer is frequently different.
