Five Private 5G Radios Connect a 400-Acre Autonomous Copper Mine

Posted by on

Private 5G deployments are often discussed in terms of factories, warehouses, ports and campuses, but mining is another environment where the characteristics of private cellular networks can make a lot of sense.

A recent deployment at Mariana Minerals' Copper One mine in southeastern Utah provides an interesting example. According to a more detailed case study subsequently published by Celona, a private 5G network covering the approximately 400-acre operational site uses just five outdoor radios and was deployed in roughly 35 days from the first conversation to the network going live.

The relatively small number of radios is perhaps the first thing that stands out. Mining sites can cover large areas, with equipment moving continuously between different parts of the operation. Providing reliable connectivity across that environment is very different from covering an office or conventional industrial building.

The more interesting part of this deployment, however, is what the network is being used for.

Mariana Minerals acquired the Copper One operation, formerly Lisbon Valley Mining Company, in late 2025. The wider permitted land package covers around 10,000 acres, while the private 5G deployment described by Celona covers the approximately 400-acre operational area. Mariana describes Copper One as an "autonomy-first" mine and refinery, with the company attempting to integrate mining, refining and project execution through its own software platform, MarianaOS.

Private 5G provides the connectivity layer underneath this software-defined approach.

Celona and Mariana announced the network in April 2026, describing it as the communications backbone for MarianaOS. Data from equipment, sensors and other systems flows over the private network into the platform, where it can be used for real-time monitoring, analytics and operational decision-making.

One of the clearest examples is drilling. MarianaOS can send optimised drill patterns to autonomous drilling equipment while geological information generated during drilling is sent back towards the control systems. According to the companies, a single operator can remotely manage multiple autonomous drills. The resulting information is also used to continuously update the site's digital representation, improving subsequent drilling decisions.

Mariana is working with Sandvik on this part of the operation. Sandvik's AutoMine Surface Drilling autonomous platform is being integrated with MarianaOS rather than operating as an isolated automation system. The objective is to allow drilling information to become part of the wider mine operating environment, while operators supervise several machines rather than manually controlling individual drills.

Autonomous drilling is only one part of the story. When Mariana restarted mining operations at Copper One, it outlined a wider automation stack including autonomous haulage technology from Pronto, Sandvik's autonomous drilling platform and Boston Dynamics Spot robots. Spot is intended to patrol areas including the open pit, heap leach pad and refinery infrastructure, acting as a mobile sensing platform whose data can also feed into MarianaOS.

This is where the private network becomes particularly interesting.

It is easy to look at private 5G as simply another way of providing wireless connectivity. In an environment such as Copper One, however, connectivity becomes part of the operational control architecture.

The chain increasingly looks something like descrived in image below:

Mariana itself describes what it is building as Physical AI at scale. Its software platform combines geologic modelling, mine planning, fleet orchestration, plant control, maintenance and other operational information, with machine learning and reinforcement learning used to optimise areas such as drilling, haulage, plant throughput and energy consumption.

Private 5G therefore does not create the autonomous mine on its own. Instead, it provides one of the foundations needed to make the wider system work.

This distinction is important when considering the business case for private networks.

Enterprises rarely need 5G simply because it is 5G. The value appears when wireless connectivity removes an operational constraint or enables something that would otherwise be difficult to implement reliably.

Mining is a good example because equipment is highly mobile, sites can be large and harsh, and continuously collecting information from moving assets can be difficult. Traditional Wi-Fi will continue to have an important role at industrial sites, but wide-area mobility and the need to maintain connectivity to machines moving around an open mine create a different set of requirements.

Celona says Copper One had previously relied on a combination of legacy Wi-Fi and manual data collection. The private network creates a more consistent site-wide wireless layer for equipment and operational systems.

There is also an interesting architectural aspect to the deployment.

Celona has been moving towards what it calls AerFlex, an AP-only private 5G architecture that removes the requirement for a dedicated 5G core appliance or server at every site. Control functions are handled through the cloud, while data-path functions and local breakout remain at the access point. This is intended to reduce the amount of specialist infrastructure needed at remote or distributed locations.

This type of architecture could be particularly relevant for sectors such as mining, energy, utilities and logistics, where private networks may need to be deployed at many geographically distributed sites without a large local IT or telecoms team.

The fact that Celona says the 400-acre Copper One deployment required only five outdoor radios and around 35 days to deploy is therefore significant. It starts to move private 5G away from the perception that every deployment has to resemble a miniature mobile operator network requiring a lengthy integration exercise.

Of course, the real test will be how the network and autonomous systems perform as the mine scales.

Copper One is not being positioned as a technology demonstration. Mariana restarted mining operations there in April 2026 and plans to expand combined copper output substantially while extending autonomous control across mining and refining. The company has also attracted significant new investment, announcing a $310 million Series B in August 2026, bringing total parent and project capital raised to approximately $400 million.

For private networks, deployments such as this are arguably more interesting than another isolated proof of concept.

Five radios covering a 400-acre mine is a useful technical headline, but the bigger story is that those radios are becoming part of the infrastructure connecting autonomous drills, haul trucks, robots, sensors, software platforms and AI-driven decision making.

As industrial AI increasingly moves from analysing information to controlling machines in the physical world, reliable wireless connectivity becomes much more important.

Private 5G may therefore find some of its strongest use cases not as a replacement for every existing wireless network, but as the connectivity backbone for machines that increasingly need to sense, communicate, decide and act in real time.
