11 JULY 2024
540,000 oz GOLD at 4.1 g/t INITIAL JORC MINERAL
RESOURCE ESTIMATE AT IDENBURG
The directors of Far East Gold (FEG or the Company) are pleased to announce an independent initial
total JORC inferred resource estimate (MRE) of 540,000 ounces of gold @ 4.1 g/t and 468,000
ounces of silver at 3.6 g/t at the Company’s Idenburg Project. This initial JORC resource estimate
was determined by SMG Consulting from 3 of the 14 prospects identified within the 95,280 ha
Idenburg CoW. The inferred resource estimate was achieved without any additional drilling by
completing additional topographic surveying over the prospect areas to provide more precise data.
HIGHLIGHTS:
•
Total inferred JORC resource estimate of 540,000 ounces gold at a grade of 4.1 g/t and
468,000 ounces of silver at a grade of 3.6g/t.
•
The total resource is comprised from the Sua, Bermol and Mafi prospects using historical
drillhole data supplemented by newly acquired topographic survey data and revised 3D
deposit modelling. These prospects are 3 of the total 14 prospect areas identified by
historical exploration and determined to be valid resource targets by SMGC.
•
Previous exploration focused on only about 30% of the total CoW area and most of the
property remains vastly under-explored and holds potential for an expansion of the
contained resources.
•
The resource estimates are consistent with the initial exploration targets determined by
SMGC in the June 2024 Exploration Target Report released by the Company on August
21, 2024.
•
The Company is confident of expanding the initial JORC gold-silver resource through
a planned detailed surface mapping and sampling program followed by a Phase 1 drill
program, including within the 3 prospects mentioned in the report.

Figure 1: Map showing the location of the Idenburg COW in Papua Indonesia relative to the locations of world class
multimillion ounce gold-rich porphyry copper deposits.
The Idenburg Project is situated within the Keerom and the Pegunungan Bintang Regencies of Papua
(Figure 1), near the border with Papua New Guinea. The all-weather Trans Irian Highway is an
asphalted road from the regional capital of Jayapura that transects the Exploration COW and allows
for relatively easy access and cost-effective logistical support (Figure 2). Compared to other projects
in Papua logistical support is simple and cost-effective especially when compared to the other major
producers in Papua.
Field observations show that the basic style of gold mineralisation as determined from mapping and
drill core logging is of the orogenic gold type, also referred to as mesothermal lode gold. The presence
of coarse gold with a high nugget value is inherent to deposits of this type and will need to be evaluated
when sampling or assaying. In June 2024, SMGC reported Exploration Targets for all 14 prospects
identified within the Idenburg CoW area. Refer to the independent SMG Consultants (SMGC) report
titled Pt. Iriana Mutiara Idenburg Exploration Targeting Report of June 2024 that was included in the
Company’s ASX announcement of August 21, 2024.

Figure 2: Map showing the location of the Idenburg COW and prospect areas identified by historical exploration. The Sua,
Bermol and Mafi prospects comprise the current JORC 2012 inferred resource estimate determined by SMGC.
A total of 59 drillholes have been drilled in the Idenburg project area, consisting of 22 in Sua, 7 in
Bermol, 23 in Mafi, 3 in Selia, and 4 in Sikrima (Figure 2). Drilling was conducted in two periods. The
first period occurred prior to Avocet's involvement in 2000, during which a total of 23 holes were
drilled—all in the Mafi Prospect. The second period took place between 2005 and 2007 and was
carried out by the Avocet and Idenburg Joint Venture. Refer to an independent review of historical
exploration results by SMGC in the Company’s ASX announcement dated August 21, 2024.
For the JORC Mineral Resource estimation SMGC completed a thorough review of the historical
Idenburg geological database to assess if the data was suitable to support the estimating and reporting
of Gold Resources by a Competent Person according to the 2012 JORC Code. Based on their
interpretation SMGC determined that the necessary criteria were met with the exception of additional
topographic data and some additional QA/QC sampling of historical drill core. With completion of this
additional work SMGC determined that the zones of mineralisation delineated within the Sua, Bermol
and Mafi prospects areas could be classified as a `Mineral Resource’ according to the 2012 JORC
Code standards as stated below:
FAR EAST GOLD ASX ANNOUNCEMENT

IDENBURG GOLD PROJECT ACQUISITION
IDENBURG – INITIAL JORC RESOURCE
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)
Generally, the parameters which are considered for classification of the Mineral Resource are the
distribution and density of drill data, confidence in interpreted geological continuity of the mineralised
zones, and confidence in the resource block estimates. SMGC used the historical exploration data to
build three geological models for the Sua, Bermol and Mafi Prospects. In interpreting the 2012 JORC,
SMGC was of the opinion that the deposits in the three prospective areas could only be categorized
as Inferred Resources (Table 1). SMGC estimated the ore tonnage for the three prospect areas using
a cut-off grade of 0.1 g/t Au with no grade capping applied to the IMI historical assays.
Table 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.
To estimate grades for Sua and Mafi, SMGC applied the Inverse Distance Weighting (IDW) method.
This method assigns a value to a grid node by calculating the weighted average of either all data
points or a selection of neighbouring points distributed in various directions. Each data point’s value
is weighted based on the inverse of its distance from the grid node, squared. The choice of the
exponent’s value determines the degree of localisation in gridding, with higher exponents leading to
a more localised influence of distant points on the value assigned to each grid node. There was no
grade capping applied in the IMI geological modelling.
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.

IDENBURG GOLD PROJECT ACQUISITION
IDENBURG – INITIAL JORC RESOURCE
SMGC created 3 geological models created for the Idenburg JORC resource estimate. The area
covered by the 3 models are: 1) Sua: ~ 900 m x 960 m; 2) Bermol: ~ 1,240 m x 1,280 m; and 3) Mafi:
~ 500m x 460 m. The geological models for each mineral resource area are shown below.
Sua Prospect
The gold mineralisation occurs in a system of boudinage quartz veins with an NNE trend and moderate
NNW dip, hosted by silica-sericite-chlorite-pyrite altered diorite. Calc-silicate veins occur peripheral to
the mineralisation. The quartz veins vary in thickness from a few millimetres up to 3 metres. The
quartz veining is associated with late-stage deformation and many local shears are mineralised with
gold and sulphides. The IMI geologists have observed in the field and in the drill core that the gold
mineralisation also tends to follow meta-lithological contacts, such as the transition zones between
the different metamorphic grades. Gold mineralisation has been interpreted and modelled as a
stacked quartz vein system that dips moderately at around 35 degrees towards the north. The vein
system seems to be associated with the thrusting event and runs parallel to the thrusts as described
above.
A total of 21 wireframes were modelled by SMGC as representation of the known gold-bearing quartz
veins at the Sua Prospect (Figure 3). The wireframes were extended beyond the drilling and trench
information along strike and down dip. The extension distance was established largely on the expected
continuity based on field mapping plus experience with similar style structures. The maximum distance
that wireframes were extended was 50 metres beyond drillholes.

IDENBURG GOLD PROJECT ACQUISITION
IDENBURG – INITIAL JORC RESOURCE
Bermol Prospect
A well-mineralised quartz-sulphide vein zone has been mapped over 600 metres of strike length and
over a width of 300 metres on the two main NS-trending ridges at Bermol. This is a single thrust plane
that dips at less than 25 degrees to the west and appears to have multiple zones by virtue of both the
topographic effect and faulting. Mineralisation is associated with quartz-pyrite-arsenopyrite "augen"
veins hosted in a tightly constrained envelope of sheared quartz-chlorite-carbonate altered schists. This
is reflected in the high As values in samples collected from Bermol, often exceeding 1%. Vein attitudes
are predominantly conformable with schistosity and foliation trends. Gold mineralisation has been
modelled as a single vein structure that has been downthrown by faulting towards the north on the
western side of the river and outcrops at a higher elevation on the eastern side. This has resulted in 5
discrete vein models. There were 5 wireframes modelled as representation of the known gold bearing
quartz veins at the Bermol Prospect.
Figure 4: Bermol Mineralisation Wireframe Oblique View
Mafi Prospect
Gold mineralisation at Mafi occurs in the oxidised, silicified ultramafics in vuggy, brecciated sulphidequartz veins, which form a shallow (10º to 40º) west-dipping tabular zone. The description of the
mineralisation suggests epithermal affinities. If the mineralisation coincides with a thrust, steeper feeder
zones may be present either beneath the thrust, particularly if the mineralisation is restricted laterally.
Outcropping mineralisation has been traced sporadically over a distance of 6 kilometres and possibly
continues further south along the Mafi River Thrust Fault to Bermol, 15 kilometres to the south.

SMGC created only one wireframe for the Mafi geological model (Figure 5). Twenty-three (23)
boreholes were drilled, but only 12 holes intersected the wireframe.
Figure 5: Cross Section of Mafi Borehole Sample Au Assays with Mineralization Wireframe
Future Exploration
As part of the mineral resource estimation SMGC also recommended a future work program to expand
the areas of defined mineral resources at the Sua, Bermol and Mafi prospect areas and delineate
additional resources in the other prospect areas identified. SMGC is of the opinion that future work
programs should include:
• A revised interpretation of remote-sensed imagery, incorporating new findings from prospect-level
exploration, should facilitate vectoring towards potential extensions and/or new areas of mineralization
in the Kali Kae, Tekai, Kimly, and North Bermol Prospects.
• Infill and step-out drilling at Sua, Bermol, and Mafi: Infill drilling will provide better constraints on the
initial Inferred Mineral Resource and test for potential steeper feeder structures beneath the thrust.
Step-out drilling will confirm the along-strike continuity of the mineralization and validate the surrounding
Gold Exploration Targets.
• Future infill drilling campaigns should be accompanied by comprehensive metallurgical sampling at
Sua, Bermol and Mafi, including the viability of recovering Pb, Zn and Cu sulphide mineralisation.
• A review of pathfinder elements in drill core and soil databases to ascertain vectors to mineralisation
for use in prospect-scale programs.
• Application of detailed magnetic and IP dipole-dipole geophysics to existing prospects to better
understand the structural controls and potential extensions to zones of known mineralisation.
The Company is currently finalising a comprehensive exploration program to include the SMGC
recommendations.

JORC Code explanation
Commentary
• 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 drill core was digitally photographed and logged by project geologists. Core
with any potential for mineralisation was marked up for sampling and despatched
to an analytical laboratory for geochemical analysis. Only obvious nonmineralised core was not sampled.
• Half core was selected for geochemical analysis.
• The 2007 drill core sample intervals range from 1.00 to 2.00 m with an average
interval of 1.38 m.
• All 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
• 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 precollar.
• 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.

• Core was fitted together and 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 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 indicate no relationship between grade and recovery.
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 may have occurred due to preferential loss/gain of fine/coarse
material.
Logging
• Whether core and chip samples have been geologically and geotechnically
logged to a level of detail to support appropriate Mineral Resource estimation,
mining studies and metallurgical studies.
• Whether logging is qualitative or quantitative in nature. Core (or costean,
channel, etc) photography.
• The total length and percentage of the relevant intersections logged.
• All drill holes were logged by geologists.
• All logging data recorded intervals 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
techniques and
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.
• For all sample types, the nature, quality and 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 representative of the in-situ
material collected, 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 the analysis including instrument make and
model, reading times, calibrations factors applied and their derivation, etc.
• All samples were dispatched to an 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.

• Nature of quality control procedures adopted (eg standards, blanks, duplicates,
external laboratory checks) and whether acceptable levels of accuracy (ie lack of
bias) and precision have been established.
• The verification of significant intersections by either independent or alternative
company personnel.
• The use of twinned holes.
• Documentation of primary data, data entry procedures, data verification, data
storage (physical and electronic) protocols.
• Discuss any adjustment to assay data.
• Analysis by Sucofindo of replicate assays and duplicate pulp check assays
indicate acceptable levels of accuracy and precision.
• Accuracy and quality of surveys used to locate drill holes (collar and down-hole
surveys), trenches, mine workings and other locations used in Mineral Resource
estimation.
• Specification of the grid system used.
• Quality and adequacy of topographic control.
• Soil sampling grid (Northing, Easting, and Elevation) was established with
handheld GPS control and tape and compass surveyed in the rugged terrain.
• There is no clear information on whether the borehole collars to date have been
surveyed using standard total station techniques or GPS handheld equipment.
• Both Sua and Bermol have been topographically surveyed by site surveyors with
a soil sampling grid established and surveyed over the project. Survey data of
creek locations, ridges, and spot heights 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 for reporting of Exploration Results.
• Whether the data spacing and distribution is sufficient to establish the degree of
geological and grade continuity appropriate for the Mineral Resource and Ore
Reserve 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.
• 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.
• Samples are not composited for analysis. Down-hole compositing is applied for
Mineral Resource estimation
• Whether the orientation of sampling achieves unbiased sampling of possible
structures and the extent to which this is known, considering the deposit type.
• Drill sections are oriented perpendicular to the main strike of shallow dipping vein
structures.
• Most holes were drilled on section.

Commentary
to geological
structure
• 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.
• Vertical and mostly inclined holes were drilled, depending on the 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 mineralisation.
• All drill core samples were packed on-site into polysacks by experienced IMI
personnel before being helicopter delivered to the IMI logistic depot near
Jayapura Airport and ai
