■ Extensive piloting and demo plant delivered
consistent results, validated by multiple
independent parties
Demo plant processed 5.2M liters of brine
into 200K 12 liters of concentrate and
produced ~1,300 kg of battery grade lithium
carbonate (>99.5% purity) in one of the
largest known DLE-to-BG carbonate test
program
Achieved 99.9% impurity rejection, 80%
lithium recovery, 93% plant uptime while
using 10x less freshwater, 7x less land and
generating 55x less waste than evaporation
ponds

11 See the Company's JORC technical report dated effective December 19, 2023, "Kachi Lithium Brine Definitive Feasibility Study" for full details regarding material assumptions relied upon. Lake confirms the material assumptions in that announcement continue to apply and
have not materially changed. 12 200K+ litres of concentrate processed but only 120K was used to produce battery grade lithium carbonate. The excess remain in storage.
