Mariana Minerals Copper One: the world's only autonomy first mine

San Juan County is stepping up for national security and American prosperity. Critical minerals. High-paying jobs. Built here. 🇺🇸

Grateful to everyone who joined us for the First Blast at Copper One. It was a meaningful moment for our team and the local community. A special thank you to @GovCox for your leadership and support, and to our incredible team at Copper One. This achievement is a direct result of your hard work and commitment. We are excited to bring new jobs to San Juan County and help strengthen the U.S. critical minerals supply chain. We're just getting started!

We’ve deployed Spot® from @BostonDynamics at Copper One! Not as a standalone tool, but as part of an autonomy-first system. Integrated into MarianaOS, Spot® delivers continuous thermal, acoustic, and visual data into real-time operations. This is the shift: 𝙥𝙚𝙧𝙞𝙤𝙙𝙞𝙘

Autonomous trucks + software-defined operations are coming to copper mining. Integrated systems like MineOS are enabling coordinated, data-driven production—helping get more critical minerals out while creating new jobs. @MarianaMinerals is putting it into practice with

Turner Caldwell, Co-Founder and CEO of @MarianaMinerals, will join us at the Operation Gigawatt Summit on May 22. Mariana Minerals is building a new model for critical mineral supply chains in the United States: full stack, software-driven, and built for speed. That upstream

We just opened applications for the Mariana Minerals Summer 2026 Internship Program! This is not a typical internship. Interns here work on the systems that power modern energy, AI, and defense – and the work directly contributes to our ability to move faster, operate better, and build a stronger supply chain for critical minerals. This will be our first class of interns, and we’re being intentional about keeping it small and high impact. We’re a software-first minerals mining and refining company, and that is reflected across our entire organization. Our interns will work at the intersection of software, hardware, and real-world operations, solving important problems that don’t come with easy answers.
