Any links that provide the ability to invest in a primary or secondary transaction in a company are for convenience only and do not constitute solicitations or offers to buy or sell an investment. Investors should exercise heightened precaution and due diligence when investing in private companies, especially those not independently audited.

While we strive to provide valuable insights with objectivity and professional diligence, we cannot guarantee the accuracy of the information provided on our platform. Before making any investment decisions, you should verify the accuracy of all pertinent details for your decision.

Announcing Copper One: The World's Only Autonomy-First Mine and Refinery

Announcing Copper One: The World's Only Autonomy-First Mine and Refinery

Located in southeastern Utah, Mariana Copper One is an operating copper mine and refinery currently producing high-purity copper cathode for the U.S. market. The site was acquired in late 2025 and has been operating for over 15 years, with an existing open pit mine, heap bioleaching operation, and hydrometallurgical refining circuit.

Mariana plans to deploy PlantOS at scale to maximize copper recovery, restart mining operations with autonomous equipment via MineOS, integrate copper scrap processing into the refining circuit, and scale combined output to 50,000 metric tonnes per year from both geologic and scrap feedstocks.
