Ann: Outstanding Initial Well Test Results at HMW Project, page-2

Just what the doctor ordered

Highlights:
• 72-hour constant rate testing successfully completed at first Pata Pila pumping
well (PPB-01-21).
‒ Brine sampling confirms high grade resource (Li > 910 mg/L).
‒ Hydraulic testing saw aquifer response showing favourable conditions for
high volume brine production (15 – 20L per second).
• 30-day longer term pumping test started and flowing steadily.
• Porosity test (RBRC) for specific yield on second Pata Pila well core samples
returned positive results (range of 10.1 – 21.0%, mean of 14.1%).
• Pumping tests to be completed on three further wells; a second well at Pata Pila
and two wells at Rana de Sal.
• Testing of first well at Rana de Sal (PBRS-01-21) is imminent.
