Elang Block II

Expenditure:
e Exploration activities included drilling and geological mapping. Costs were circa USD
$5.25M.

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

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).
#  Alteration analyses using an ASD TerraSpec 4 Mineral Spectrometer.

Objectives:

e 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 mineral resource
classifications. Drilling in progress at Elang South is testing mineralisation extension
to the south and at depth extension of the Cu-Au resource block model.

e Exploration drilling at Alma tested for potential Cu-Au porphyry mineralisation
beneath a lithocap (Figure 3).

e Exploration drilling at Sebu East tested for potential Cu-Au porphyry mineralisation
within a significant IP conductivity and resistivity anomaly (Figure 3).

Exploration Results:

» Elang Block diamond drilling (9 holes for 4,831.7 m):

o Elang Cu-Au resource infill & exploration - 7 holes, completed or in progress,
totaling 4,031.5 m.

o Alma Cu-Au exploration - 1 hole completed, amounting to 204.0 m.
o Sebu East Cu-Au exploration - 1 hole completed, amounting to 596.2 m.

# Core samples submitted to the assay lab amounted to 2,098.

e# Geological mapping program - 55 rock samples were submitted to the lab.

Forward Plan:
e# Elang deposit resource development drilling, geotechnical drilling, hydrogeological
drilling, and metallurgy drilling, using six (6) rigs, is planned for 43-2024.
» Sebu East exploration drilling (1 rig), over a porphyry Cu-Au target, will continue in
04-2024.
