Elang Block II

Expenditure:
   • Exploration activities included drilling and geological mapping. Costs were circa USD $ 2.68 M.

Work Areas:
   • Elang Cu-Au Project
   • Alma Cu-Au Project
   • Sebu East Project.

Exploration Parties:
    • Manager - AMNT Exploration.
    • Drilling contractor - PT Minera Nusa Drillindo (PT MND).
    • Assay Laboratory (drill core, rock) - Intertek Utama Service (ITS).

Assessment Methods:
   • Diamond drilling (3 rigs).
   • Geological mapping (including rock sampling).
   • Alteration analyses using an ASD Terra Search 4 Mineral Spectrometer.

Objectives:
   • Resource development drilling continued at the Elang Cu-Au deposit (Figure 3). The purpose
        of this infill program was to explore information gaps, improve the geological model and
        increase the confidence level of resource classifications.
   • Exploration drilling at Alma tested for potential Cu-Au porphyry mineralization beneath a
        lithocap (Figure 3). Detailed geological mapping was also undertaken.
   • Detailed geological mapping at Sebu East over a significant IP conductivity and resistivity
        anomaly (Figure 3).

Exploration Results:
    • Elang Block diamond drilling (21 holes for 3,688.8 m):
            o Elang Cu-Au resource infill – 17 holes, completed or in progress, totaling 2,227.8 m.
            o Alma Cu-Au exploration – 4 holes, completed or in progress, amounting to 1,461.0 m.
    • Core samples submitted to the assay lab amounted to 1,373.
    • Geological mapping program:
            o Sebu East - 63 rock samples were submitted to the lab.
            o Alma - 49 rock samples were submitted to the lab.
    • The Elang Mineral Resource Estimate (MRE) was updated.

Forward Plan:
   • Elang resource definition diamond drilling (2 rigs) will continue in Q1 2024.
   • Alma exploration diamond drilling (1 rig) will continue in Q1 2024.

Rinti Block III

Expenditure:
   • Exploration drilling program and geological mapping costs (including core sample and rock
       assay costs) amounted to approximately USD $ 0.46 M

Work Areas:
   • Rinti Cu-Au Project.

Exploration Parties:
    • Manager - AMNT Exploration.
    • Drilling contractor - PT Minera Nusa Drillindo (PT MND).
