Elang Block II

Expenditure:
e Exploration activities included drilling, IP Survey acguisition and geological mapping.
Costs were circa USD $ 2.2 M.

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).
e IP Survey - PT Geo Services

Assessment Methods:
e Diamond drilling (3 rigs)
e IP (Induced Polarization) Survey resistivity and chargeability.
» Geological mapping and soil sampling
e 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 alithocap and diatreme breccias (Figure 2).

e IP Surveys at Sebu East and Gerbang East were a follow up to previous porphyry
exploration work.

e Geological mapping and grid soil sampling was conducted along the Sebu East IP
survey lines. The objective is to delineate the extent of the surficial Cu-Au
geochemical anomalies and to define new drill targets.

Exploration Results:
e Elang Cu-Au project diamond drilling (7 holes for 3,500.70 m):
o Resource infill, Elang - 4 holes (2,162.0 m) completed or in progress,
o Exploration drilling, Gerbang East - 3 holes (1,338.70 m) completed or in
progress.
e IP Survey acguisition - 11 lines (19.7 km) completed.
e Core samples submitted to the assay lab amounted to 1,479.
e# Geological mapping program - 94 rock samples and 41soil samples from Sebu East
were submitted to the lab.

Forward Plan:
e Continue resource drilling at Elang, exploration drilling at Gerbang East and
exploration drilling at Sebu East using 3 rigs.

Rinti Block III

Expenditure:
e  Exploration activity - IP Survey preparation. Costs were circa USD $ 37.7 K

Work Areas:
e  Rinti Cu-Au Project.

Exploration Parties:
# Manager - AMNT Exploration.

Assessment Methods:
e IP Survey preparation, setting lines by Total Station (TS) and tape compass method.

Objectives:
e IP (Induced Polarization) survey will test a lithocap system in the southern part of
Rinti. This IP survey program aims to identify the potential for an underlying Cu-Au
porphyry system beneath the lithocap (Figure 3).

Exploration Results:
e IP Survey preparation - 8 lines (11.35 km), 6596 complete

Forward Plan:
e IP Survey data acguisition 11.35 km at SW Rinti.
#  Exploration drilling (1 rig) at lithocap zone.
