- Lucas: So there's this image most of us have when we think about mining. Hard hats, headlamps, tunnels full of dust, diesel trucks rumbling in the dark. That picture is still real in a lot of places, but the most technologically advanced mines in the world right now look almost nothing like it. Luna: And the technology driving that shift is 5G. Specifically private 5G networks that mines are deploying deep underground or across open pits. Lucas: Exactly. And this is not a future scenario. I'm talking about networks that are live today. The most cited example is Rio Tinto's Koodaideri mine in Western Australia. That's an iron ore operation that went live with a private 5G network in 2025, and it's basically a test bed for full autonomy. Luna: What does full autonomy mean in a mining context? Because 'autonomous' gets thrown around a lot. Lucas: Good question. At Koodaideri, it means haul trucks that drive themselves — no driver in the cab — carrying ore from the dig site to the crusher. It means drill rigs that can be operated from a surface control room a thousand kilometers away in Perth. And it means real-time data from sensors on conveyors and crushers that lets operators adjust the process without ever setting foot in the pit. The 5G network is the backbone that makes all that possible, because you need ultra-reliable low-latency communication — U-R-L-L-C in the 3GPP specs — to control a 200-ton truck moving at 40 miles per hour. Luna: And they trust 5G for that? I mean, if the network drops out for a second, that truck could be a problem. Lucas: That's exactly why it has to be a private network, not public 5G. Private networks give the mine operator full control over coverage, capacity, and reliability. They can deploy small cells along the haul roads, put antennas in the tunnels, and engineer the network for something like 99.9999 percent uptime. That's six nines. And the latency targets are under 10 milliseconds. That's fast enough for real-time remote control of machinery. Luna: So what's the incentive for a mining company to invest in this? The upfront cost for a private 5G network is not trivial. Lucas: No, it's not. But the return on investment comes from two big buckets. First, safety. Mining is dangerous. In 2024, there were over 40 fatalities in Australian mines alone, and countless near-misses. Removing people from the high-risk zones — the pit, the underground face — dramatically reduces that risk. Second, productivity. Autonomous haul trucks can operate 24-7 without breaks, and they can be optimized for fuel efficiency and tire wear. Rio Tinto reported that its autonomous trucks at other sites before 5G already delivered a 15 percent productivity gain. With 5G, they're targeting 30 percent or more, because the data pipeline is faster and richer. Luna: And it's not just Rio Tinto. BHP has been doing similar work at its Jimblebar iron ore mine, also in Western Australia. They're using 5G for remote operation of loaders and drills. Lucas: Right. And the vendor ecosystem is interesting here. Nokia has been the most aggressive in mining. They have a whole 'Nokia 5G for Mining' portfolio, and they've done deployments with both Rio Tinto and BHP. Ericsson is also active, but more on the infrastructure side, partnering with mining equipment makers like Caterpillar and Komatsu. So you've got the traditional telecom vendors betting big on this vertical. Luna: What about underground mines? The open pit case is one thing, but underground is a whole different environment — thicker rock, tunnels that curve, no GPS. Lucas: That's where the technology really proves itself. Underground is incredibly challenging for wireless because of the rock density and the geometry. But companies like Nokia and a startup called Softil have been deploying 5G in underground copper mines in Chile and gold mines in South Africa. In Chile, for example, Codelco has a trial at its El Teniente mine — that's one of the largest underground copper mines in the world. They're using 5G to remotely operate LHDs — load haul dump machines — that move ore from the stope to the ore pass. Early results show they can operate those machines from the surface with a control latency that feels almost real-time. Before 5G, they were using Wi-Fi, which had too much jitter and packet loss to be reliable for remote operation. Luna: So 5G essentially enables a level of remote control that wasn't possible with previous wireless technologies. Lucas: That's the core insight. Wi-Fi wasn't designed for mobility at high speed. It wasn't designed for handoffs between access points without a delay. And it certainly wasn't designed for the kind of deterministic latency that remote control requires. 5G, especially in its private network flavor, is built for that. And mining is one of the first industries where the economics are aligning to justify the investment. A single autonomous haul truck costs around $5 million. If 5G lets that truck run 30 percent more shifts per year, the payback on the network is measured in months. Luna: And there's the edge computing angle, too. You can't send all that video and sensor data back to a central server hundreds of miles away. The latency would kill you. Lucas: Exactly. That's why mines are also deploying edge compute nodes on site. The 5G network connects the equipment to a local server rack that processes the data in real time. Only aggregated insights are sent to the cloud. So it's a combination of private 5G and edge computing that makes the whole system work. And that's a pattern we're seeing in other industries — manufacturing, logistics, ports — but mining might be the most extreme case because of the harsh environment. Luna: It's also worth noting that this is a global trend. Australia and Chile are leading, but there are trials in Canada, Sweden, and even parts of Africa. The mining industry is surprisingly global in its tech adoption. Lucas: It is. And the equipment makers are standardizing on 5G. Caterpillar, for example, announced in 2025 that its new autonomous trucks would be 5G-ready by default. That's a huge signal because Cat controls a massive share of the mining equipment market. When the OEM builds it in, adoption accelerates. Luna: You know, this kind of specific, technical conversation about a niche industry — it's exactly why we keep this podcast ad-free. It's not something you'd hear on a mainstream business show. If this episode gave you a new way to think about 5G's real-world impact, consider supporting us at buy me a coffee dot com slash fexingo. That's buy me a coffee dot com slash fexingo. Keeps us independent and focused on the details that matter. Lucas: Yeah, entirely listener-supported. No sponsors, no pressure. Just the content we think is actually useful. And speaking of useful — I want to close with a forward-looking thought. The mining industry is on track to become one of the biggest buyers of private 5G networks globally. By 2030, analysts estimate that mining will account for about 12 percent of all private 5G spending. That's billions of dollars. And the reason is simple: safety and productivity improvements that pay for themselves. So the next time you drive past a construction site or watch a documentary about a mine, remember — the network that's silently running those machines is probably 5G. Luna: And it's bringing the oldest industry on earth into the digital age, one private network at a time. Thanks for listening, everyone.
