A prefeasibility study (PFS) into the Kachi lithium brine project, in Argentina, has found that the project could support an annual production of 25 500 t/y of battery grade lithium carbonate over a mine life of 25 years.
ASX-listed Lake Resources on Thursday said that the PFS estimated a start-up capital investment of $544-million would be required, with operating costs estimated at $107-million a year.
