Ann: Colina High Grade Results, page-53

1. Best Case Scenario:

   • Tonnage Range: 60 to 70 million tonnes. This optimistic projection is based on the assumption of extensive mineralized zones that have not been fully explored or accounted for in previous estimates. The potential for high-quality lithium deposits, coupled with advanced extraction technologies, supports this upper-end estimate.
   • Grade Range: 1.5% to 1.8% Li2O. The higher grade is indicative of rich lithium deposits, suggesting a concentration of lithium-bearing minerals that are economically viable for extraction. This grade range would place the deposit among the higher-grade lithium resources globally, reflecting efficient mining and processing techniques.

2. Average Case Scenario:

   • Tonnage Range: 50 to 60 million tonnes. This scenario assumes a more conservative expansion of known mineralized zones. It's a balanced estimate that considers both the potential for new discoveries and the limitations imposed by geological factors and current mining technology.
   • Grade Range: 1.2% to 1.5% Li2O. This grade is typical for commercially viable lithium deposits. It reflects a balance between quantity and quality, ensuring economic feasibility without reaching the upper echelons of lithium concentration.

3. Worst Case Scenario:

   • Tonnage Range: 45 to 50 million tonnes. This lower range considers the possibility that additional exploration might not significantly expand the known resources. It also accounts for geological challenges or lower than expected quality in unexplored sections.
   • Grade Range: 1.0% to 1.2% Li2O. While still commercially viable, this grade range suggests a lower concentration of lithium. This could result from geological variability or the inclusion of lower-grade material in the resource estimate, which would require more intensive processing.
