Mariana Minerals Secures $310 Million Series B Financing to Expand Critical Minerals Projects
Mariana Minerals has raised $310 million in Series B funding, led by Khosla Ventures and supported by several other investors. The capital will be used to expand the company's portfolio of critical minerals projects and further develop its proprietary software platform, MarianaOS. The financing brings the total parent and project capital raised to approximately $400 million. Mariana uses AI-driven platforms like CapitalProjectOS, PlantOS, and MineOS to streamline mining operations and reduce timelines significantly compared to industry standards. The funds will support key projects such as Copper One in Utah and Lithium One in Texas. Mariana aims to develop 10 commercial-scale critical minerals projects within a decade using its software-first approach. CEO Turner Caldwell emphasized that the company is transitioning from proving their model to scaling it, with each project generating data to improve future operations.
