While much of the tech world focuses on high-end manufacturing, Turner Caldwell is looking at the very bottom of the supply chain. A former Tesla engineer with a decade of experience, Caldwell believes the mining industry is stuck in a pre-digital era. To fix it, he founded Mariana Minerals in 2024, a startup designed to modernize mineral extraction through heavy automation and vertical integration.
A Software-First Approach to Mining
Caldwell argues that legacy mining companies resemble the “Big Three” automakers before Tesla or NASA before SpaceX. These incumbents often rely on manual reporting, walkie-talkies, and spreadsheets—methods that work for meeting basic KPIs but leave massive efficiencies on the table.
To bridge this gap, Mariana Minerals developed MineOS, a proprietary coordination layer designed to manage every aspect of a mine. Rather than just selling software, Caldwell’s goal is to sell refined metal, using his technology to optimize the entire process from the ground up.
The Partnership: Autonomous Haulage in Utah
The company is moving quickly from theory to practice. Mariana Minerals recently announced a partnership with Pronto, an autonomous vehicle startup specializing in off-road environments. Pronto was recently acquired by Atoms, a robotics venture led by Uber co-founder Travis Kalanick, reuniting him with Pronto founder Anthony Levandowski.
Next week, this partnership goes live at Copper One, a formerly idled mine in Utah that Mariana purchased last year. The integration will allow:
- Autonomous Dispatch: Haulage trucks will be coordinated via MineOS without human intervention.
- Route Optimization: Software will manage traffic flow and logistics across the site.
- Reinforcement Learning: The system will use real-time data to improve operational decisions over time.
Solving the Labor Crisis
The move toward autonomy isn’t just about cutting costs; it’s an answer to a dwindling workforce. As Western mining companies have failed to innovate, they have struggled to attract new talent. Caldwell believes that by making mines more productive through technology, the industry can actually expand.
By treating the mine as a data-driven ecosystem rather than a manual labor site, Mariana Minerals aims to revitalize domestic mineral production and secure the raw materials essential for the modern economy.
