Slide 5: MT Geophysics – outstanding low resistivity provides bullseye drill targets
MT Geophysics – outstanding low resistivity provides bullseye drill targets Extends to 1,000m+ depth below 3.0 ohm.m rsonal use only 500mdepth 1,122 ppm MT Survey Line 2300 in northern section of the project Lithium sample The geophysics show two hot spot zones with a resistivity below 0.5 Ohm-m on
Slide 6: Cilon - Drill Hole – JAM 26-08
Cilon - Drill Hole – JAM 26-08 rsonal use only Due to water location constraints, we drilled the blue arrow location which intersected The basement at 440m depth. The resistivity was very low and influenced by the clay Matrix but the visible porosity was higher than expected.
Slide 7: Cross section of major aquifers
Cross section of major aquifers rsonal use only The lower and upper sand units are the key aquifer units. The Ignimbrite volcanic unit is a Reliable marker for the various lithologies. Jam 24-01 and Jam 24-02 recorded Li content Of 580 ppm. Vizcachera values are higher than expected: two INLAB sampl

Slide 11: MRE - Formentera Inferred and Indicated Resource Statement
MRE- Formentera Inferred and Indicated Resource Statement rsonal use only 11,000L tank being filled with lithium brine from well JAM 25-06. It was filled 21 times During the pump test.
Slide 12: Formentera lithium concentration
Formentera lithium concentration The high porosity zone lithium content is 469ppm Lithium rsonal use only The thickness of the zone is approximately 200m but the MT geophysics shows it extends 500m The lithium average across all 34 samples is 279ppm SD=standard deviation, CV=coefficient of variation
Slide 13: BMR - Exceptional Porosity – Jam 26-06 Zone 7-8
BMR -Exceptional Porosity – Jam 26-06 Zone 7-8 rsonal use only JAM 26-06 shows eight aquifer zones – zone 7 and 8 – 273m-462m shows mostly sands. Average total porosity is 18-19%% and SY has an average of 8% in zone 3 and 12% in zone 4.
