Terra AI builds an AI platform for modeling and optimizing large-scale natural resource and mineral exploration projects, with tools that characterize deposits, quantify uncertainty, and help plan drilling. Its website says it works with explorers and cites use in subsurface exploration, and Built In lists the company as based in Palo Alto, California. The company says its patented AI fuses exploration data into multimodal models, generates many possible subsurface models, and uses those results to improve targeting and drill planning. Terra AI’s site also says it has secured more than $100 million in investment for partners.
