Investor Presentaiton

Lithium Prices Are Surging Low-cost sedimentary extraction to take advantage ARIZONA LITHIUM Industry leading sedimentary Lithium peer advantages • Shallow, low-cost mining • Low stripping ratio • Minimal requirement for crushing/grinding • Scale to support long mine life Lithium mineralisation hosted by sediments deposited in a N-S oriented basin Lithium mineralised sediments, up to 50m in thickness are covered by a thin veneer of transported colluvium (5-10m thick) Lithium Deposit Types Estimated Cost (Li₂CO3) Mine Product Typical Grade SEDIMENTARY ~ $4,000/tonne Lithium Carbonate/ Hydroxide 1,000-3,000 ppm Li BRINE $2,500 $4,000/ tonne HARDROCK $6,000/tonne Lithium Carbonate (Li2CO3) Spodumene Concentrate (6% Li20) 500-1,000 ppm Li 4,500-7,000 ppm Li Production Steps Mining, Leaching, Evaporation & Crystallization Pumping of Brine Evaporation & Crystallization Mining Crushing & Grinding Roasting Acidification arizonalithium.com 7
