Elang Block II

Expenditure:
e Exploration activities included drilling and geological mapping. Costs were circa USD
S3.59M.

Work Areas:
e Elang Cu-Au Project.
» Gerbang East Cu-Au Project
e Sebu Cu-Au 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 (4 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 2). 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.

e# Exploration drilling at Gerbang East is testing for Cu-Au porphyry mineralisation
potential below a lithocap and diatreme breccias (Figure 4).

e Exploration drilling at Sebu East is designed to test a coincidental Induced
Polarisation (IP) chargeability high and magnetic (ASVI) anomaly beneath a lithocap.

e Geological mapping at Sebu East is intended to follow up on the porphyry
mineralization indications from a previous scout drilling program.

Exploration Results:
e Elang Cu-Au project diamond drilling (10 holes for 5,262.40 m):
o Resource infill, Elang - 7 holes (2,449.40 m) completed or in progress,
o Exploration drilling, Gerbang East - 2 holes (1,828.90 m) completed or in
progress,
Oo Exploration drilling, Sebu East - 1 hole (984.10 m) completed.

e Core samples submitted to the assay lab amounted to 4,013.

Forward Plan:
e Continue infill resources drilling at Elang and exploration drilling (3 rigs) at Gerbang
East.
e IP geophysical survey (19.65 line km) at Sebu East and Elang NE.
