SUA PROSPECT – DRILL PROGRAM EXTENDED
Far East Gold Limited (“FEG” or “the Company”) advises that following completion of drilling for the
Company’s 10-hole diamond drill program at the Sua Prospect and receipt of high-grade assay results
from the first four holes, the Board has approved a focused extension to the current drilling program.
The extension comprises a further five step-out diamond holes for approximately 1,360m, targeting
down-dip and along-strike extensions to the high-grade gold zones intersected in holes KSD023 to
KSD026.
HIGHLIGHTS
• Strong historic foundation at Sua
Two phases of historic diamond drilling in 2005 and 2006 (22 holes for 2,629m) intersected
gold mineralisation in 19 holes within the current resource footprint.
Historic drilling results include, 7.5m @ 13.6 g/t Au from 21m (KSD002), 3.0m @ 35.0 g/t Au
from 107m (KSD008) and 16m @ 8.49 g/t Au from surface including 1m @ 105 g/t Au
(KSD013).
• FEG drilling confirms and upgrades high-grade potential
FEG has completed 10 diamond drillholes at Sua (KSD023–KSD032) for a total of 1,836m.
Assays received for the first four holes (KSD023–KSD026) have all intersected high-grade
gold mineralisation, including previously reported bonanza-grade intervals (see Table 1 and
ASX announcement dated 15 December 2025).
• High-grade stacked vein system open along strike and down-dip
Gold is hosted in a system of stacked, NNE-trending quartz veins dipping ~35° to the north
within the Sua–Afley shear zone.
Mineralisation remains open along strike and down-dip beneath both historic and recent
drilling.
• Extension program approved – 5 step-out holes for ~1,360m
New priority holes PKSD011–PKSD015 (see Table 3) are designed as ~100m down-dip
step-outs beneath recent FEG holes KSD027, KSD028, KSD026, KSD030 and KSD031.
The program is aimed at testing continuity and plunge of high-grade shoots within the stacked
vein system.
• Positive historic metallurgy
Preliminary metallurgical test work by IMI indicated 50–60% gravity recoverable gold and
overall CIL/RIL recoveries exceeding 90%, suggesting the mineralisation is amenable to
conventional processing methods (subject to further confirmatory test work).

GEOLOGICAL AND HISTORIC DRILLING CONTEXT
The Sua Prospect lies within FEG’s Idenburg Gold Project in Papua Province, Indonesia, along the
Sua–Afley shear corridor (Figure 1).
Figure 1: – Geology of the Idenburg Inlier showing the Sua–Afley Shear Zone and prospects within the Contract
of Work area.
The shear hosts a system of boudinaged quartz veins with a NNE trend and moderate north to NNW
dip, developed within silica–sericite–chlorite–pyrite altered diorite and associated meta-sedimentary
rocks. Calc-silicate veins occur peripheral to the mineralisation and many local shears are mineralised
with gold and sulphides. Gold mineralisation also tends to follow meta-lithological contacts, such as
the transition zones between different metamorphic grades.
Gold at Sua has been interpreted and modelled as a stacked quartz vein system dipping at
approximately 35° toward the north and parallel to thrust structures recognised in the area (See Figure
2 for mineralisation wireframe oblique view).

the current JORC (2012) inferred mineral resource estimate (included in the Idenburg JORC Resource Report;
model unchanged – see FEG’s ASX Announcement dated 16 December 2024).
Historic drilling at the Sua Prospect was completed in two phases of diamond drilling in 2005 and
2006, comprising 22 holes for 2,629m. Mineralised intercepts were recorded in 19 of the 22 holes; the
four non-mineralised holes (KSD009, 012, 018 and 020) were located on the eastern and western
flanks of the drilled area. Historic intercepts from included:
• 4m @ 5.96 g/t Au from 41m (KSD001)
• 7.5m @ 13.6 g/t Au from 21m (KSD002)
• 1m @ 33.8 g/t Au from 123m (KSD004)
• 9m @ 4.00 g/t Au from 80m (KSD005)
• 3.0m @ 35.0 g/t Au from 107m (KSD008)
• 3m @ 17.7 g/t Au from 55m (KSD010)
• 1m @ 23.0 g/t Au from 77m (KSD021)
Near-surface oxide mineralisation was also intersected, including 16m @ 2.38 g/t Au from surface
(KSD001), 18m @ 2.05 g/t Au from surface (KSD010), and 16m @ 8.49 g/t Au from surface including
1m @ 105 g/t Au (KSD013).
Preliminary metallurgical test work conducted on surface samples and drill core composites indicated
that 50–60% of gold is recoverable by gravity, with overall CIL or RIL recoveries exceeding 90%.
These data underpin the existing JORC (2012) inferred mineral resource estimate and vein wireframe
model at Sua (See FEG’s ASX Announcement dated 16 December 2024).

FEG SUA DRILLING PROGRAM UPDATE
FEG’s initial diamond drilling program at Sua comprised 10 holes (KSD023–KSD032) for 1,836m. The
program was designed to:
• Twin key historic holes to validate earlier results and sampling quality;
• Step out along strike and down-dip over the existing resource footprint; and
• Improve structural understanding of the stacked vein system and Sua–Afley shear corridor.
Assay results reported to date for KSD023 and KSD024 confirmed near-surface bonanza-grade gold
associated with milky quartz–sulphide veins, validating historic drilling and demonstrating robustness
of the mineralised system. Subsequent results from KSD025 and KSD026, which targeted the same
high-grade zone as historic hole KSD008 and tested the zone approximately 50m down-dip,
intersected further high-grade mineralisation across multiple stacked veins, including deeper high-
grade zones not fully defined in earlier drilling.
Selected previously reported intercepts from KSD023–KSD026 are summarised in Table 1.
Table 1: Selected previously reported high-grade diamond drill intercepts from FEG holes KSD023–KSD026 at
the Sua Prospect (see FEG’s ASX Announcement dated 15 December 2025).

FAR EAST GOLD ASX ANNOUNCEMENT 5
The high-grade zones intersected in KSD023–KSD026 remain open at depth and along strike. Assays
for the remaining six holes from the initial program (KSD027–KSD032) are pending and will be
reported once received and interpreted.
Details of the completed FEG drillholes are provided in Table 2.

EXTENSION OF SUA DRILL PROGRAM
On the basis of:
• the strong historic drilling dataset;
• the high-grade results from FEG holes KSD023–KSD026; and
• improved structural understanding from drilling, mapping and 3D modelling,
the Company has approved a focused extension to the Sua drill program.
The extension comprises five additional diamond holes (PKSD011–PKSD015) for a total planned
meterage of 1,360m (see Table 3), all located within the existing Sua drill grid see (Figure 3).

FAR EAST GOLD ASX ANNOUNCEMENT 7
The five holes are designed as down-dip step-outs of approximately 100m beneath recent FEG holes,
with the objectives of:
• testing continuity of high-grade gold mineralisation down-dip and along strike from existing
intercepts;
• better defining the geometry and plunge of high-grade shoots within the stacked quartz vein
system; and
• generating additional data to support future assessment of potential resource growth and
classification upgrades at Sua, should results warrant.
The first extension hole, PKSD011, is planned from an existing pad, enabling drilling to commence
promptly following finalisation of operational approvals for the extended program.
IDENBURG PROJECT AND SUA RESOURCE
The Sua Prospect is one of several prospects within the Idenburg Gold Project (Figure 1), which
currently hosts a JORC (2012) inferred mineral resource of approximately 540,000 oz Au at an
average grade of 4.1 g/t Au, including an estimated 296,000 oz Au at an average grade of 3.7 g/t Au
at Sua (See FEG’s ASX Announcement dated 16 December 2024).
A total of 21 stacked quartz vein wireframes representing gold-bearing lodes at Sua were utilised by
SMGC in the inferred JORC mineral resource estimate. These wireframes extend up to 50m along
strike and down-dip beyond drilling based on mapped continuity and experience with similar structural
settings (See Figure 2). Results from FEG’s initial drilling and the approved extension program will be
incorporated into the geological model and assessed for their impact on the existing resource in due
course.
NEXT STEPS
• Receive and report assay results for KSD027–KSD032 from the initial 10-hole program.
• Commence drilling of the five-hole, ~1,360m extension program (PKSD011–PKSD015).
• Continue detailed mapping and structural interpretation along the Sua–Afley shear zone to
refine additional targets.
• Integrate new drilling data into the existing Idenburg resource model and evaluate implications
for potential resource growth and classification at Sua and other prospects.
The Company will provide further updates as results from both the remaining initial holes and the
extension program become available.

APPENDIX 1
Idenburg Mineral Resource Statement
The Company confirms that it is not aware of any new information or data that materially affects the
information included in the Idenburg Mineral Resource estimate and all material assumptions and
technical parameters underpinning the inferred mineral resource estimate continue to apply and have
not materially changed when referring to its resource announcement made on 16 December 2024
“Amended Idenburg Announcement and Independent JORC Resource Report”. The Company
confirms that the Competent Persons’s findings are presented and have not been materially modified
from the original market announcement.
Table 1 (Appendix 1): Mineral Resource table as estimated by SMGC based on historical exploration data
using a cut-off grade of 0.1 g/t Au with no grade capping applied to the IMI historical assays. The resource
tonnage is estimated based on a specific gravity of 2.8 t/m3. Gold recovery of 90% was based on historical
preliminary metallurgical testing completed on Sua drill core composites.
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.

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 Sua drill core is digitally photographed and
logged by FEG project geologists. Core with any
potential for mineralisation was marked up for
sampling and dispatched to an analytical
laboratory for geochemical analysis. Only
visually obvious non-mineralised core was not
sampled.
• Cut, half core was selected for geochemical
analysis.
• The drill core sample intervals range from
0.5 to 1.50 m in length.
• All half core samples were jaw-crushed and split
onsite in the Company operated core facility.
Sample packets of 500g were put into woven
polysacks by site personnel and air freighted to
PT.Geoservices in Bekasi, West Java,
Indonesia.
• Additional sample preparation and assays were
undertaken by the independent Pt. Geoservices
laboratory in Bekasi, Indonesia.
• Gold analyses of all drill core samples were by
fire assay with atomic absorption spectrometry

sampling by a geologist, and where loose
fragments were seen core was wrapped in masking
tape prior to the core sawn in half.
Drill sample
recovery
• Method of recording and assessing core and
chip sample recoveries and results assessed.
• Measures taken to maximise sample recovery
and ensure representative nature of the samples.
• Whether a relationship exists between sample
recovery and grade and whether sample bias

extent to which this is known, considering the
deposit type.
• If the relationship between the drilling orientation
and the orientation of key mineralised structures
is considered to have introduced a sampling
bias, this should be assessed and reported if
material.
• Drill sections are oriented perpendicular to main
strike of shallow dipping vein structures.
• Most holes were drilled on section.
• Vertical and mostly inclined holes were drilled,
depending on the interpreted orientation of the
shear/fault zone hosting the mineralisation.
