Domestic manufacturing has taken center stage in America. Yet, Turner Caldwell, a man whose resume is inked with nearly a decade at Tesla, sees the conversation as too shallow. All eyes are on factories and assembly lines, but few glance below—to the hidden core of the supply chain, where ores and unrefined metals shape the world’s ambitions.
That frustration fueled his leap from the electric vehicle giant to founding Mariana Minerals in 2024. The company’s premise is blunt and targeted: overhaul mining, modernize it, and ultimately flood the market with refined metals—the very foundation for batteries, electronics, and the machinery of tomorrow.
But Caldwell isn’t interested in the slow trickle of incremental upgrades. He’s after transformation. At Mariana Minerals, nearly every cog of a mining operation is being primed for automation. The latest step? Ditching traditional vehicles for autonomous ones.
On Thursday, Mariana Minerals unveiled its partnership with Pronto, a young company specializing in self-driving tech for the rough terrain of mines and construction sites. These aren’t theoretical systems; Pronto equips hulking trucks to pilot themselves through the dust and danger of underexplored lands.
This agreement marks Pronto’s first major move since its acquisition by Atoms—the robotics venture helmed by Travis Kalanick, infamous Uber co-founder. In a turn of Silicon Valley drama, Kalanick is now back in league with Anthony Levandowski, Pronto’s creator and a controversial figure from Google’s early self-driving escapades. Their paths, which once converged at Otto (later scooped up by Uber), intertwine again.
For Caldwell and Mariana, autonomy isn’t just another buzzword. It’s a tool for erupting change at Copper One, a copper mine in Utah that lay dormant until they acquired it last year. Next week, autonomous haulage trucks will rumble across its grounds—an early glimpse at mining’s possible future. The deal’s financial terms remain under wraps.
But putting robots behind the wheel isn’t the full story. Caldwell’s ambitions run deeper. Pronto’s self-driving system is about to fuse directly with Mariana’s in-house software, “MineOS.” Picture this: a digital nerve center that doesn’t just track machinery, but autonomously dispatches trucks, orchestrates routes, and knits together the chaos of extractive industry—all with scant human intervention.
What Caldwell envisions is a web of operating systems tied together by reinforcement learning. Systems that learn on the job, catching inefficiencies humans miss, and steadily shaving away waste. Miners, Caldwell insists, have for too long mirrored the inertia of old Detroit automakers before Tesla, or NASA before the rise of private spaceflight. Many leaders in legacy mining remain comfortable with clipboards, spreadsheets, and the clunky flow of radio chatter. Why uproot routines if performance metrics are met?
But Caldwell sees a crisis simmering beneath that comfort. Western mining, he points out, builds little new infrastructure—attracting scant new talent. With an aging, thinning workforce, the sector is left scrambling to squeeze more from less. For him, Mariana’s software-first path offers a lifeline.
The company is, first and foremost, in the business of selling metal. Still, Caldwell doesn’t rule out licensing their MineOS software to other players—eventually. His focus, though, is on vertical integration: mining the ore, refining the metal, controlling the coordination, all under one roof. “You can’t be SpaceX just selling rocket-landing code to NASA,” he tells me, his comparison unvarnished.
There’s another reason Mariana insists on hands-on ownership. Reinforcement learning needs data, the richer and dirtier, the better. By running their own mines, Mariana can generate volumes of nuanced operational data, letting their algorithms glimpse patterns hidden to humans—much like AlphaGo’s uncanny moves in Go, once it had marinated in enough games.
For all his talk of code and algorithms, Caldwell bristles at any notion of a workerless mine. He’s blunt: “We’re not automating to cut people out. We’re automating so the people we have can do more—and so we can run more mines, period.” To him, smart autonomy broadens, not narrows, the doors for tomorrow’s workforce.
He’s pragmatic about the stakes. Mariana could thrive. If the model scales, so could an industry. But beneath the logic and the lines of code, there’s a stubborn optimism that mining—long dismissed as backward—can lead tech’s next frontier, with people still at its core.
