TSX-V-listed Plateau Energy Metals this week shared its Falchani project preliminary economic assessment (PEA), which finds that the project can become a large, long-life producer of low cost and battery-grade lithium carbonate (Li2CO3). The PEA envisions an average production capacity of about 63 000 t/y over 33 years, with steady state production being able to reach 85 000 t/y of Li2CO3.
