Mariana Minerals builds and operates copper and lithium mines and refineries using AI, automation, and its proprietary software platform, MarianaOS. Founded in 2024, the company acquires underperforming or idle mineral assets, then restarts and scales them faster than conventional operators by layering autonomous orchestration, machine learning, real-time telemetry, and robotic equipment on top. Its current flagship sites are Copper One — a previously idled copper mine in southeastern Utah targeting 50,000 metric tons of refined copper per year — and Lithium One in East Texas, which extracts lithium from oil-and-gas produced water and aims to be the world's first GWh-scale facility of its kind. MarianaOS acts as the operating brain: every project feeds data back into the platform, lowering the cost and time to build the next one. Buyers are energy, defense, and technology companies that need domestically sourced copper, lithium, and other critical minerals. The company's stated ambition is 10 commercial-scale projects in 10 years.
