Mariana Minerals

Mariana Minerals is a software-first, vertically integrated critical minerals company founded in 2024 that owns and operates mineral projects end-to-end — including an operating copper mine in southeastern Utah and a lithium extraction facility under construction in East Texas — using its proprietary AI platform, MarianaOS, to streamline permitting, construction, extraction, and refining. Backed by $120M from Andreessen Horowitz, Breakthrough Energy Ventures, and Khosla Ventures, the company aims to bring 10 mineral projects into production within 10 years to supply minerals critical to energy, AI, and defense technologies.
