Drilling Commences at High-Grade Sua Prospect
Far East Gold Limited (ASX: FEG) is pleased to announce that diamond drilling has commenced at
the high-grade Sua prospect, one of the most advanced and highest-grade gold targets within the
Company’s Idenburg Contract of Work in Papua Province, Indonesia.
The program will consist of 10 diamond drill holes for a total of 1,820 metres and will run in parallel
with the project’s ongoing North Bermol drill program and the soon to commence program at the
Kwaplu Prospect. Drilling is designed to confirm and extend high-grade zones of gold
mineralisation previously intersected in historical drill programs and to advance the geological
model of the broader Sua-Afley Shear Zone, a 5 kilometer long structural corridor.
HISTORICAL DRILLING – Demonstrated High Grades and Continuity:
The Sua prospect was last drilled in 2005-2006 by Avocet Mining. Results were exceptional, with 18
of 22 holes intersecting gold mineralisation, including multiple high-grade intercepts:
• KSD001: 16m @ 2.38 g/t Au from 0m and;
4m @ 2.31 g/t Au from 22m and;
5m @ 1.69 g/t Au from 33m and;
4m @ 5.96 g/t Au from 41m; including 2m @ 11.4 g/t Au from 43m.
• KSD002: 7.5m @ 13.6 g/t Au from 21m and;
2m @ 8.78 g/t Au from 78m.
• KSD005: 9m @ 4.0 g/t Au from 80m, including 1m @ 25.8 g/t Au.
• KSD008: 5m @ 21.8 g/t Au from 107m; including 3m @ 35.0 g/t Au from 107m.
• KSD010: 18m @ 2.05 g/t Au from 0m and;
8m @ 2.58 g/t Au from 44m; including 1m @ 14.3 g/t Au from 44m and;
3m @ 17.7 g/t Au from 55m and;
3m @ 2.0 g/t Au from 64m.
• KSD013: 7m @ 3.29 g/t Au from 0m and
6m @ 8.22 g/t Au; including 2m @ 52.3 g/t Au from 13m
• KSD021: 3m @ 9.56 g/t Au from 75m; including 1m @ 23.0 g/t Au from 77m.
• KSD022: 17m @ 2.88 g/t Au from 0m and:
8m @ 1.43 g/t Au from 33m and;
1m @ 3.35 g/t Au from 70m.
Over 30 gold-bearing veins were identified in the district, confirming the presence of multiple stacked
high-grade shear zones with significant potential for resource expansion.
A summary of compiled significant intersections reported from historical drilling is provided in
Appendix 1.
FAR EAST GOLD ASX ANNOUNCEMENT 1
ASX ANNOUNCEMENT
13 October 2025
Far East Gold CEO, Shane Menere, commented:
“The commencement of drilling at Sua marks another important milestone in unlocking the exceptional
potential of our Idenburg project. The historical results from Sua are nothing short of outstanding, with
multipole high grade intercepts up to 52.5g/t Au. This new drilling program is designed to confirm and
extend those results, and we are confident that it has the potential to define a significant high-grade
system. With rigs now turning at both North Bermol and Sua, far East Gold is advancing two highly
compelling prospects in parallel, both of which demonstrate the scale, grade, and continuity needed to
underpin a world-class gold project.”
CEO & Director Shane Menere has released a video discussing this announcement. Watch the video on our
investor hub here: https://fareast.gold/link/r6Vp5r
Geological and Metallurgical Confidence
- Gold mineralisation occurs within boudinaged quartz-pyrite veins hosted in altered metadiorite,
plunging ~35° to the north.
- Petrographic studies confirmed the presence of chalcopyrite, galena, sphalerite, covellite,
chalcocite, and free gold. Previous initial metallurgical test work demonstrated gravity recovery
of 50–60%, with overall gold recovery exceeding 90% using standard CIL/RIL processes –
highlighting the potential for excellent gold recovery using common industry techniques.
NEXT STEPS
The upcoming drilling campaign will test down-dip and along-strike extensions of these high-grade
zones, with the objective of confirming the continuity, scale, and resource potential of the Sua
system.
A detailed summary and interpretation of historical drilling and exploration completed at Sua is
provided in the Independent Exploration Target Report for the Idenburg Property prepared by
SMGC and released by the Company in ASX announcement of August 21, 2024
Figure 1: Map showing prospect and resource areas within the Idenburg COW tenement. Recent mapping was completed
in the North Bermol prospect area and discovered new zones of shear/fault-hosted gold mineralisation.. Refer to Figures
2 and 3. Coordinates are referenced to datum WGS84, zone 54 south.

Planned Drill Program
The Sua drill program is designed in part to confirm the geological interpretation and reported high-
grade gold zones intersected by the previous drilling (Figure 2). Previous drilling was completed at
100m spacing so the planned holes will also test the lateral continuity of intersected mineralized
zones at 25m and 50m spaced holes. See interpreted cross sections depicted in Figures 3 and 4.
Figure 2: Image showing the Sua prospect area and the locations of planned drillholes (yellow). The planned holes will
confirm mineralized zones intersected by previous drilling and the geological model applied. The program will also seek
to extend zones of high-grade mineralisation between the 100m spaced historical drilled holes. A review and discussion
of historical exploration and assessment of resource potential can be found in the Company ASX announcement of
announcement of August 21, 2024. Coordinates are referenced to datum WGS84, zone 54 south.
An initial inferred JORC 2012 resource estimate for the Sua prospect was also completed by SMGC.
Based on their assessment of the historical data SMGC estimated an inferred mineral resource of
2.5 million tonnes at an average grade of 3.7 g/t gold (Au) for a total of 296,000 ounces of gold within
the Sua prospect. Refer to the SMGC report titled ‘JORC Resource Report, PT Iriana Mutiara
Idenburg, November 2024’ released by the Company in ASX announcement of November 14, 2024.
FAR EAST GOLD ASX ANNOUNCEMENT 3
SUA – DRILLS TURNING
A ‘Mineral Resource’ is a concentration or occurrence of material of intrinsic economic interest in or
on the Earth’s crust in such form, quality and quantity that there are reasonable prospects for
eventual economic extraction. The location, quantity, grade, geological characteristics and continuity
of a Mineral Resource are known, estimated or interpreted from specific geological evidence and
knowledge. Mineral Resources are sub- divided, in order of increasing geological confidence, into
Inferred, Indicated and Measured categories (2012 JORC Code).
An ‘Inferred Mineral Resource’ is that part of a Mineral Resource for which quantity and grade (or
quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence
is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on
exploration, sampling and testing information gathered through appropriate techniques from
locations such as outcrops, trenches, pits, workings and drill holes. An Inferred Mineral Resource
has a lower level of confidence than that applying to an Indicated Mineral Resource and must not
be converted to an Ore Reserve. It is reasonably expected that the majority of Inferred Mineral
Resources could be upgraded to Indicated Mineral Resources with continued exploration.
Figure 3: Cross section showing planned holes relative to historical drill holes. Refer to Figure 2. Planned holes ( in blue)
will confirm and test for lateral extension of reported mineralized intersections. A summary of historical significant
intersections is provided in Appendix 1. A review and discussion of historical exploration and assessment of resource
potential can be found in the Company ASX announcement of announcement of August 21, 2024. Coordinates are

JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data (Criteria in this section apply to all
succeeding sections.)
Criteria JORC Code explanation Commentary
Sampling
techniques
• Nature and quality of sampling (eg cut channels, random
chips, or specific specialised industry standard
measurement tools appropriate to the minerals under
investigation, such as down-hole gamma sondes, or
handheld XRF instruments, etc). These examples should
not be taken as limiting the broad meaning of sampling.
• Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any
measurement tools or systems used.
• Aspects of the determination of mineralisation that are
Material to the Public Report.
• In cases where ‘industry standard’ work has been
completed this would be relatively simple (eg ‘reverse
circulation drilling was used to obtain 1 m samples from
which 3 kg was pulverised to produce a 30 g charge for fire
assay’). In other cases more explanation may be required,
such as where there is coarse gold that has inherent
sampling problems. Unusual commodities or
mineralisation types (eg submarine nodules) may warrant
disclosure of detailed information.
• All historical drill core was
photographed and logged by IMI
project geologists. Core with any
potential for mineralisation was
marked up for sampling and
despatched to an analytical
laboratory for geochemical
analysis. Only obvious non-
mineralised core was not sampled.
• The 2007 drill core sample intervals
range from 1.00 to 2.00 m with an
average interval of 1.38 m.
• Cut, half-core samples were
packed into woven polysacks by
experienced site personnel and air
freighted to the Sucofindo
Laboratory in Timika, Papua
Province, Indonesia.
• All sample preparation and assays
were undertaken by the
independent Sucofindo Laboratory
in Timika, Indonesia (Freeport
Industrial Park).
• Gold analyses of all drill core
samples were by fire assay with
atomic absorption spectrometry
(AAS) finish of a 50g sample, with
a detection limit of 0.01 g/t Au
(method FAS4AAS).
• For the determination of base metal
AAS analytes the Sucofindo
GAM006 – Base Metal
Determination method was used
with detection limits of Ag (0.5 ppm)
and Cu, Pb, Zn (each 5 ppm).
• For the determination of AAS
hydride analytes the Sucofindo
GAM004 – Hydride Base Metal
Determination method was used
with a 1.00 ppm detection limit for
Arsenic
Drilling
techniques
• Drill type (eg core, reverse circulation, open-hole hammer,
rotary air blast, auger, Bangka, sonic, etc) and details (eg
core diameter, triple or standard tube, depth of diamond
tails, face-sampling bit or other type, whether core is
oriented and if so, by what method, etc).
• Triple tube diamond core drilling –
fully drilled with a diamond bit
without RC pre- collar.
• Core diameter was mostly HQ,
reducing to NQ at depth.
• Down-hole surveying was routinely
conducted at 30 m intervals during
2006 and 2007 drilling.
• Core orientation was measured
using a down-hole lance to assist in
orienting structures.
Criteria JORC Code explanation Commentary

marked up for sampling by a
geologist, and where loose
fragments were seen core was
wrapped in masking tape before
the core was sawn in half.

• All holes were drilled from the
surface using conventional triple-
tube diamond drilling techniques.
Core recoveries exceeded 90% for
all mineralised intervals reported.
• All core sample recovery recorded
in logging sheet and recovery
results were assessed by project
geologists.
• No significant drilling problems
encountered resulted in very good
core recoveries.
• Statistical analyses complete
indicated no relationship between
grade and recovery.

• The total length and percentage of the relevant
intersections logged.
• All drill holes were logged by IMI
geologists.

from and to, including lithology,
mineralisation, alteration, sulphides
cited, detailed structure, and
geotechnical characteristics.
• All core was photographed.
• All samples that were identified as
having any potential mineralisation
were assayed.
Sub-sampling
techniquesand
sample
preparation
• If core, whether cut or sawn and whether quarter, half
or all core taken.
• If non-core, whether riffled, tube sampled, rotary split,
etc and whether sampled wet or dry.

appropriateness of the sample preparation
technique.
• Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.
• Measures taken to ensure that the sampling is

including for instance results for field
duplicate/second-half sampling.
• Whether sample sizes are appropriate to the grain
size of the material being sampled.
• Core samples were logged and all
intervals for analysis were marked up
by IMI geologists, mostly at 1 metre
intervals.
• Core samples for analyses were cut
in half and collected by experienced
IMI personnel.
• 2007 drill core sample intervals
ranged from 1.00 to 2.00 m with an
average interval of 1.38 m.
• Selected quarter core samples were
assayed for quality assurance and
quality control analysis.
Quality of
assay data and
laboratory tests
• The nature, quality and appropriateness of the
assaying and laboratory procedures used and
whether the technique is considered partial or total.
• For geophysical tools, spectrometers, handheld XRF
instruments, etc, the parameters used in determining

independent laboratory – Sucofindo
Laboratory, Timika, Indonesia.
• No QA/QC was conducted in the field
at all stages of exploratory sampling.
• QA/QC duplicate and replicate
sampling only conducted within the
Timika Sucofindo Laboratory.
Criteria JORC Code explanation Commentary
• Nature of quality control procedures adopted (eg
standards, blanks, duplicates, external laboratory checks)
and whether acceptable levels of accuracy (ie lack of

were also collected and all survey
data was used to create the
topography DTM.
• The existing topographic survey is
considered adequate for the
current DTM. Minor local
discrepancies are evident and
further survey work will be required
should further Resource definition
ensue.
• The grid system used is Universal
Transverse Mercator (WGS 84)
UTM Zone 54, Southern
Hemisphere.
Data spacing
anddistribution

estimation procedure(s) and classifications applied.
• Whether sample compositing has been applied.
• Drill hole spacing and drill section
spacing were as close to 100 m as
the rugged ground conditions
allowed.
• Historical drilling has verified the
mapping and trenching with the
confirmation of both strike and dip
continuity of gold-bearing quartz
veins at depth. Although the drilling
density is insufficient to allow a
detailed model of the quartz veins it
is adequate to define the overall
geometry of the veins.

orientation of the mineralisation.
• The orientation of the drilling is
considered adequate for an unbiased
assessment
of the deposit with respect to
interpreted structures and control on

also referred to as mesothermal
lode gold.
• Petrographic studies suggested the
presence of gold within intensely
sheared and deformed quartz veins
hosted in metamorphic rocks with
the types of alteration assemblages
and fluid inclusion homogenisation
temperatures indicated that an
orogenic lode gold mineral system
is present.
Drill hole
Information
• A summary of all information material to the
understanding of the exploration results including a
tabulation of the following information for all Material drill
holes:
- Easting and Northing of the drill hole collar
• See Appendix 1
Criteria JORC Code explanation Commentary
- elevation or RL (Reduced Level – elevation above
sea level in metres) of the drill hole collar
- dip and azimuth of the hole
- down-hole length and interception depth
- hole length.
• If the exclusion of this information is justified on the basis
that the information is not Material and this exclusion does
not detract from the understanding of the report, the
Competent Person should clearly explain why this is the
case.
Data
aggregation
methods
• In reporting Exploration Results, weighting averaging
techniques, maximum and/or minimum grade truncations
(eg cutting of high grades) and cut-off grades are usually
Material and should be stated.
• Where aggregate intercepts incorporate short lengths of
high grade results and longer lengths of low grade results,
the procedure used for such aggregation should be stated
and some typical examples of such aggregations should
be shown in detail.
• The assumptions used for any reporting of metal
equivalent values should be clearly stated.
• Significant intercepts were
calculated using a 0.5 ppm lower
cutoff
• No metal equivalent values
considered.
Relationship
between
mineralisation
widths and
intercept
lengths
• These relationships are particularly important in the
reporting of Exploration Results.
• If the geometry of the mineralisation with respect to the drill
hole angle is known, its nature should be reported.
• If it is not known and only the down-hole lengths are
reported, there should be a clear statement to this effect (eg
‘down-hole length, true width not known’).
• The drill targets were tested with
the aim of intersecting the
interpreted mineralised structure as
perpendicularly as possible to the
strike, based on the geological
interpretation available usually
from surface creek mapping and
mapping of trench and channel
exposures. Mineralised zones were
generally intersected at angles of
greater than 60 degrees to the dip,
which will cause a slight
overstatement of the true
mineralised width.
• Results were reported as down-
hole widths, in most cases, the true
width is approximately 80-85 % of
the down-hole length.
Diagrams
• Appropriate maps and sections (with scales) and
tabulations of intercepts should be included for any
significant discovery being reported These should include,
but not be limited to a plan view of drill hole collar
locations and appropriate
sectional views.
• Maps and tables included were
taken from historical reports and
have been determined accurate
based on subsequent Company
field work.
Balanced
reporting
• Where comprehensive reporting of all Exploration
Results is not practicable,
representative reporting of both low and high grades and/or
widths should be practiced to avoid misleading reporting of
Exploration Results.
• Results from all holes in the
historic programs for which assays
have been received are reported.
Other
substantive
exploration
data
• Other exploration data, if meaningful and material, should
be reported including (but not limited to): geological
observations; geophysical s
