Elang Block II

Expenditure:
e Exploration activities included drilling and geological mapping. Costs were circa
USD $ 2.61M.

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

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

Assessment Methods:
e Diamond drilling (3 rigs).
»  Geological mapping (including rock sampling).
e 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 to increase the confidence level of resource classifications.
Drilling in progress at Elang South is testing the southern and depth limits of the
Cu-Au resource block model.

e Exploration drilling at Alma tested for potential Cu-Au porphyry mineralization
beneath a lithocap (Figure 3). Detailed geological mapping was also undertaken.

e Detailed geological mapping at Sebu East, over a significant Induced Polarisation
(IP) conductivity and resistivity anomaly (Figure 3).

Exploration Results:
» Elang Block diamond drilling (11 holes for 4,893.6 m):
o Elang Cu-Au resource infill & exploration - & holes, completed or in
progress, totaling 3,021.8 m.
o Alma Cu-Au exploration - 5 holes, completed or in progress, amounting to
1,871.8 m.
# Core samples submitted to the assay lab amounted to 1,655.
e Geological mapping program:
o Sebu East -10 rock samples were submitted to the lab.

Forward Plan:
» Elang resource definition diamond drilling (2 rigs) will continue in @2 2024.
# Alma exploration diamond drilling (1 rig) will finish in A2 2024.
e Sebu East exploration drilling (1 rig), over a porphyry Cu-Au target, will start in G2
2024.

Rinti Block III

Expenditure:
e Exploration drilling program and geological mapping costs, including core sample
and rock assay costs, amounted to approximately USD $ 0.59 M

Work Areas:
e  Rinti Cu-Au Project.

Exploration Parties:
» Manager - AMNT Exploration.
» Drilling contractor - PT Minera Nusa Drillindo (PT MND).
e Assay Laboratory (rocks) - Intertek Utama Service (ITS).
