Stage 2 – DFS Proactively derisking Samphire through insights gained from recent ISR developers Integrating 20 years of ISR technical knowledge AGM Presentation | ASX:AGE | alligatorenergy.com.au 9 9 Stage 3 – Resource Growth to Increase Mining Inventory Significant upside to increase mining inventory from multiple areas Plumbush Blackbush • 18 Mlbs(1) to support startup mining operation at Blackbush with staged expansion. • Exploration Target of 14 - 75 Mlbs demonstrates significant potential to increase the existing Resource of 18 Mlbs, by targeting: • Blackbush strike extensions from the existing MRE • Plumbush - closer spaced drilling required to convert to potential MRE • Paleochannel system shows outstanding continuity with 72% of the prospective areas untested by modern drilling, and historical assays encountered in Kanaka sands that host Blackbush resource. • Gravity surveys have proven highly effective with findings corroborating closely with drilling data.
