31 August 2022- High-Flow, High-Grade Long-Term Pumping Test Results Continue
• Long term pumping test at Pata Pila (PPB-01-21) successfully completed; pumping rates between 17 and 20 L/s, with extracted Li grade between 821 and 927 mg/L.
• These strong outcomes support potential higher production capacity parameters for Definitive Feasibility Study (DFS) inputs.
• First pumping well at Rana de Sal (PBRS-01-21) under hydraulic testing; 72-hour constant rate test executed at steady 20 L/s and average Li grade over 945 mg/L.
• Pumping test program ongoing with 30-day pumping test at PBRS-01-21 to commence shortly, plus hydraulic testing of second Pata Pila well (PPB-02-22).
• Two (2) diamond drilling exploration wells at Rana de Sal returned thick sedimentary intersections with high Li grades (942 – 1,035 mg/L).
• Casa del Inca exploration drillhole completed at 155 metres with intervals of high porosity potential sediments underlying surface lava flows.
1 August 2022- New Pegmatite Discovery at Greenbushes South Project
• Discovery of new outcropping pegmatite with 500m+ strike length; remains open along strike with geological mapping ongoing
• New soil assays spatially associated with prior pegmatite discovery reveal up to 215 ppm Li; further soil and rock chip assay results pending
• UltraFine+ assay method also confirms presence of anomalous pathfinder element concentrations (As, Cs)
• Pilot ground geophysics program in process, consisting of passive seismic (HSVR), gravity and resistivity methods
• Processed HSVR and gravity data outcomes expected in next few weeks
14 Jul 2022 – Outstanding Initial Well Test Results at HMW Project
• 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.
15 Jun 2022 – First Pegmatite Lens Discovered at Greenbushes South
• Recent airborne radiometric, magnetic and DEM survey data processed for Greenbushes South Project
• Interpretation provided 18 key target zones for lithium pegmatites near the mineralising Donnybrook-Bridgetown Shear Zone
• Follow-up mapping and sampling of the first target site (GS11) resulted in a discovery of an approx. 200 m x 40 m outcropping pegmatite lens
