The Indicated Resource of 766 Mm³ at a grade of 306 mg/L Li equates to 234Kt of lithium as Li ion. Upon conversion of Li to lithium carbonate (Li₂CO₃) using a conversion factor of 5.324, gives an equivalent of approximately 1.3 Mt of Li₂CO₃. However, using a conservative 60% estimated total recovery return from processing gives a conservative estimate of 749 Kt of Li₂CO₃ equivalent (LCE).

In preparing this resource estimates, Geos considered and applied processes to be appropriate for brine style deposits, using the principles set out in National Instrument 43-101 ('NI 43-101'), Joint Ore Resources Code JORC (2012) for mineral projects, and CIM Best Practice Guidelines for Resource and Reserve Estimation for Lithium Brines.
