Princeton Critical Minerals (PureLi)

Princeton Critical Minerals (PCM) (formerly PureLi) is a Princeton University spin-out addressing the global supply-demand gap in critical minerals, starting with lithium from brine sources. Our three proprietary platforms combine immediate impact with long-term scalability: Lilypad doubles lithium yields in solar evaporation ponds; SmartPond uses AI-driven, real-time optimization to boost recovery; and E-LiTE makes extraction from low-grade domestic brines economically viable.

PCM has demonstrated the technologies in multiple field deployments and is generating revenue from product sales. Our suite of scalable platforms delivers both immediate impact and long-term growth for the $20B+ market. PCM welcomes investors and partners to join us in driving sustainable mineral extraction.
