Long Term Pump Test Confirms Production Aquifer Recharge

• Long-term test-pumping confirms assumptions of drainage of brine from the clay sedimentary layer into the highly permeable basal sand layer, or the lower production aquifer • The clay sedimentary layer contains over 32% of the JORC Indicated Mineral Resource estimate of 12.7Mt contained SOP • The clay continually re-charges the production aquifer over the long term, supplying brine into the prod
