The US won't test mining technology in a real mine — it will build synthetic mines for that

The US Department of Energy invested US$73 million in four testbeds dedicated to validating automation, electrification and digital connectivity before any mining company has to put its own operation at risk.

The US Department of Energy, through its Office of Critical Minerals and Energy Innovation, announced on September 9, 2026 the selection of four projects to receive US$73 million in funding under the Mine of the Future program. The stated goal is to create dedicated test grounds for mining technologies not yet mature enough to go straight into commercial operation. The four selected projects are: Innovative Wireless Technologies, headquartered in Lynchburg, Virginia, which will build a national testbed combining underground and surface environments in Julian (West Virginia), Idaho Springs (Colorado) and Blacksburg (Virginia) to validate digital connectivity and automation; the University of Arizona, which will set up an underground testbed in Sahuarita dedicated to electrification and energy management; the University of Missouri, in Rolla, which will combine an underground proving ground with an advanced comminution research center; and Southern Methodist University, which will build a synthetic mine inside a drilling and sensing facility in Navasota, Texas, to test tools, workflows and automation systems. Energy Secretary Chris Wright and Under Secretary Audrey Robertson said the goal is to take mining technology out of the lab and into the field, strengthening the domestic critical minerals supply chain.

The detail that makes this investment worth more than the dollar amount itself is the kind of problem it solves: today, a technology company developing a new automation or electrification system for mining has only two ways to prove it works under real conditions — build its own test mine, which few can afford, or ask an operating mining company to risk part of its production to validate something still unproven, which most refuse. This is the same kind of bottleneck that holds back new technology adoption in any capital-intensive, high-operational-risk industry — aviation and autonomous vehicles, for example, solved part of the problem with collectively funded test tracks and closed circuits, not by each manufacturer on its own. It is this logic that the four DOE projects replicate for mining: a public proving ground, funded with federal money, drastically reduces the cost of entry to prove that a technology works, especially for startups and mid-sized companies that lack the cash to build their own validation infrastructure. The split in focus among the four projects is not random either — it covers different stages of mining's technology risk chain: connectivity and automation in a mixed environment (West Virginia, Colorado, Virginia), electrification and energy management in isolation (Arizona), comminution — the crushing and grinding stage that consumes most of a processing plant's energy — combined with underground testing (Missouri), and a complete synthetic mine to simulate entire workflows, from drilling to sensing (Texas). By funding specialized testbeds instead of a single generic model mine, the program recognizes that each family of technology — fleet automation, equipment electrification, underground sensing — has its own maturation cycle and needs a test environment designed specifically for it.

For mining technology companies, the program lowers one of the barriers most often cited in any survey on automation adoption in the industry: the cost and risk of proving a system works before selling it to a real operation. For mining companies, especially smaller ones that cannot afford to test unproven technology in their own production, the testbeds work as a public filter — technology that comes out validated from a proving ground like these reaches the mine far more mature than it would straight from the lab. And for those following the geopolitical race for critical minerals, the investment signals a shift in emphasis in US policy: instead of focusing efforts only on speeding up permits for new mines, the government is also funding the technology validation infrastructure that determines how fast innovation actually reaches the mine floor.
