*Inferred tonnes one drill hole within 225x300m with at least 3 composites used in the estimation; Indicated tonnes minimum 2 drill holes within 150x200m with at least 4 composites used in the estimation.
Contained metal does not allow for mine and metallurgical recovery. 1.8 tonnes/m3 tonnage factor used.
Reasonable prospects of economic extraction by open pit mining established using: $3.00 Lithium Carbonate USD/lb, 92% metallurgical recovery, $69 USD/tonne processing, $2.35 USD/tonne Mining;
Rounding errors may exist

* Inferred tonnes within 213 meters of nearest drill hole with at least 3 composites used in the estimation; indicated tonnes two drill holes within 143 meters with at least 6 composites used in the estimation.
Contained metal does not allow for mine and metallurgical recovery.
1.96 tonnes/m3 tonnage factor used.
Economic assumptions for cutoff grade are the same as for the Stage I (PCD) Lens PAEE: $3.50 lithium carbonate/lb, 60% metallurgical recovery.
$50/tonne processing, $2.20 USD/tonne mining.
Rounding errors may exist.
