Golden Ridge Project, NE Tasmania
Drilling Extends High-Grade Gold
Mineralisation
Highlights
• Latest shallow diamond drilling program at Golden Ridge Project
successfully completed with nine holes drilled for 670 metres. Assays for
the final three holes (EVD007-009) return narrow mineralised intervals.
• Mineralised quartz-sulphide veins intersected in all nine holes,
including significant intervals (previously reported)1
of:
EVDD006: 2.5m @ 6.3g/t Au from 37.3m, including:
0.3m @ 22.2g/t Au and 0.25m @ 35.1g/t Au
EVDD003: 1.8m @ 1.9g/t Au from 43.2m, including
0.3m @ 9.9g/t Au.
• Results confirm the regional granodiorite-sediment contact as a
significant exploration target with high-grade gold mineralisation
identified over 9km of contact.
• Recent drill results are not included in the Golden Ridge Exploration
Target announced in November 2024 (see details on Page 8). Work in
2026 to focus on expanding the Exploration Target.
• Drilling at Golden Ridge has previously returned high-grade
intersections >100g/t Au (see details on Page 8).
• New drilling program at the nearby Mangana Project extended with
two drill holes completed to date and an extra third drill hole underway.
• For further information or to post questions, go to the Flynn Gold Investor
Hub at https://flynngold.com.au/link/eY2KGr
Flynn Gold Limited (ASX: FG1, “Flynn” or “the Company”) is pleased to
report final assay results from recently completed diamond drilling at the
100%-owned Golden Ridge Project in northeast Tasmania (see Figure 7).
Drilling and surface sampling by Flynn Gold has now delineated an extensive
intrusive-related gold system (IRGS), with mineralisation extending over a
9km-long zone along the margins of the Golden Ridge Granodiorite and
enclosing Mathinna Group metasediments (Figure 1).
The Company’s ongoing work at Golden Ridge is continuing to identify and
test multiple targets, increasing confidence in known areas of high-grade gold
mineralisation and confirming the potential for Golden Ridge to be a large-
scale gold discovery.

Managing Director and CEO, Neil Marston commented:
“Exploration and drilling completed by Flynn Gold in 2025 has been successful in expanding the
scale of the gold system at its flagship Golden Ridge Project in NE Tasmania. Drilling and surface
sampling results over a nine-kilometre-long contact zone confirm the scale potential of this
substantial intrusive related gold system. Further drilling is now being planned for 2026 to expand
the resource target within this extensive gold zone.
“Meanwhile, drilling is progressing well at our nearby Mangana Project with two drill holes
completed and a third drill hole in progress following a decision to expand the program. Initial
samples are with the laboratory and we look forward to reporting assay results in early 2026.”
Double Event Prospect, Golden Ridge
The Double Event Prospect at Golden Ridge is located approximately 1km north of Flynn’s high-
grade Trafalgar gold discovery, along the Golden Ridge granodiorite-metasediment contact zone
(Figure 1 & Figure 2). Historical gold workings at Double Event were first recorded in Tasmanian
Government reports from 18992
, which describe a steeply north-dipping quartz vein hosted within
weathered granite.

Diamond Drilling Program
The latest diamond drilling program at the Golden Ridge Project comprised nine drill-holes
(EVDD001-EVDD009) for a total of 670m (Figure 2). The program consisted of a series of short,
closely spaced holes designed to test the high-grade quartz-sulphide veins reported in historical
records and confirmed in recent trenching3
at the Double Event Prospect. This close spacing was
intended to assess the trend, plunge and strike continuity of the high-grade gold mineralisation.
Drilling successfully intersected the target vein structures in every hole, confirming the presence
of significant gold mineralisation to a depth of at least 72m below surface. The program has defined
two significantly mineralised discrete quartz veins within a broader approximately 30-metre-wide
corridor that also contains additional sub-parallel quartz sulphide veins and veinlets.
Full assays have been received with significant results previously reported4
including:
EVDD006: 2.5m @ 6.3g/t Au from 37.3m, including
0.3m @ 22.2g/t Au and 0.25m @ 35.1g/t Au
EVDD003: 1.8m @ 1.9g/t Au from 43.2m,including
0.3m @ 9.9g/t Au
Refer to Table 1 for the list of significant intervals for drillholes EVDD001-009 (also see Figure 2,
3 and 4 below) and Table 2 for full drill-hole collar information.

Golden Ridge Project – Background
Exploration undertaken by Flynn at the Golden Ridge Project has identified extensive intrusive-
related type gold mineralisation (IRGS) extending over a 9km-long zone along the southern contact
margin of the Golden Ridge Granodiorite and enclosing metasediments (Figure 1).
Previous drilling at Flynn’s most advanced Trafalgar Prospect has delivered multiple high-grade
gold intercepts. Previously reported drilling results from the Trafalgar Prospect included multiple
intersections grading >100g/t Au5

The combined Exploration Target at Golden Ridge only encompasses areas where Flynn had drill-
tested vein mineralisation at Trafalgar, Brilliant and Link Zone Prospects (see Figure 6) and does
not include areas of anomalous soil geochemistry such as Grenadier and Double Event, which the
Company considers to be highly prospective for gold mineralisation.
Exploration and drilling activities in 2025 have been aimed at growing the Golden Ridge Exploration
Target.

Mangana Project – Drilling Update
Drilling commenced at the Mangana Project, which is located approximately 25km south-west of
the Golden Ridge Project, in mid-November 2025 (see Figure 7).
Two diamond drill-holes were planned at the Golden Entrance Mine to test for high-grade gold
mineralisation beneath the historical workings in a zone that has not been previously drill tested.7
To date two drill-holes have been successfully completed and the program has been extended with
a third drill-hole currently in progress. Core samples from the first drill-hole and a portion of the
second drill-hole are currently in the laboratory for analysis.
The program has been paused for the Christmas period with drilling and processing of the
remaining drill core to re-commence in early January 2026.
Full details of the drilling program will be released with the assay results when they are received
in 2026.

JORC Code Table 1 for Exploration Results – Golden Ridge Project
Section 1: Sampling Techniques and Data
Criteria JORC Code explanation Commentary
Sampling
techniques
Nature and quality of sampling (e.g.
cut channels, random chips, or
specific specialised industry
standard measurement tools
appropriate to the minerals under
investigation, such as downhole
gamma sondes, or handheld XRF
instruments, etc.). These examples
should not be taken as limiting the
broad meaning of sampling.
The sampling described in this report refers to diamond drilling.
References to previous diamond drilling, trench channel sampling, rock-
chip sampling and soil sampling results relate to previously reported data,
with corresponding FG1 ASX announcements cited in the report body.
Samples were collected by qualified geologists or under geological
supervision. The nature and quality of sampling is carried out under QAQC
procedures as per industry standards.
Include reference to measures taken
to ensure sample representivity and
the appropriate calibration of any
measurement tools or systems used.
Diamond drilling
Diamond core is sampled to geological boundaries with sample lengths
generally between 0.2m and 1.0m.
The core is cut on site and half core sampled. The remaining half core is
stored on site. Care is taken when sampling the diamond core to sample
the same half side of the core as standard practice.
Certified reference material (CRM) standards are inserted at least every
20 samples. Blank samples are also inserted at least every 20 samples.
Duplicate samples are routinely submitted and checked against originals.
Aspects of the determination of
mineralisation that are Material to
the Public Report.
Diamond drilling Photon Assay
Drill core samples are sent to On Site Laboratory Services in Bendigo.
Samples are weighed, dried and crushed to -2mm, and rotary split into a
Chrysos jar (500g nominal). The residual sample is retained.
Samples are assayed for gold via photo assay method PAAU2. Pho-ton
assay is a non-destructive assay method.
PAAU2 has a detection range of 0.01 to 350 ppm Au.
Additional sampling using various techniques and duplicate samples is
ongoing to allow an assessment of any sampling issues. Current results
appear to be consistent with historical drilling assay results associated
with gold mineralisation at Golden Ridge.
Drilling
techniques
Drill type (e.g. core, reverse
circulation, open-hole hammer,
rotary air blast, auger, Bangka,
sonic, etc.) and details (e.g. 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.).
Flynn Gold Diamond drilling
HQ drill core, orientated using a Boart Longyear Truecore UPIX core
orientation tool. Orientation line was marked on the base of the drill core
by the driller or offsider. A standard 3m triple tube core barrel was used.
Drill sample
recovery
Method of recording and assessing
core and chip sample recoveries and
results assessed.
Length based core recovery was measured from reassembled core for
every drill run. Data was recorded into a digital RQD spreadsheet which
was then uploaded to Flynn Gold’s SQL database.
Core recovery was considered high (>95%). The drilling method
employed, including triple tube, lead to good core recovery.
Due to consistently high recovery, no relationship between grade and
recovery is evident.
Measures taken to maximise
sample recovery and ensure
representative nature of the
samples.
Triple tube diamond core drilling techniques are used.
The core recovery is logged for each run of drilling and measured against
the drilled length.
Generally, sample weights are comparable, and any bias is considered
negligible.

Criteria JORC Code explanation Commentary
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.
No relationship has been noticed between sample recovery and grade.
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.
Diamond drilling
Geotechnical logging is performed on the racks in the company core shed.
Core orientations marked at the drill rig are checked for consistency, and
base of core orientation lines are marked on core where two or more
orientations match within 10 degrees. RQD measurements (cumulative
lengths of core >10cm in a meter) are made on a metre-by-metre basis.
Diamond core is geologically logged for weathering, oxidation, lithology,
grainsize, alteration, mineralisation, vein types and vein intensity,
structure, and magnetic susceptibility. Structural measurements are
recorded with a protractor (alpha) and beta strip, and converted to dip
and dip-direction, or plunge and plunge direction measurements using
geological software.
Logs are recorded using a standardized logging template, which is
transferred to the company database when logging of the entire hole is
complete.
The geological and geotechnical logging is completed to a sufficient level
to support appropriate future geological, Mineral Resource estimation,
mining, and metallurgical studies.
Whether logging is qualitative or
quantitative in nature. Core (or
costean, channel, etc) photography.
Diamond drilling
Where logs cannot be taken quantitatively using percentages or
numerical scales, standardized descriptors to describe texture, lithology,
alteration and mineralisation are used. Geologists have the option to
provide more information through qualitative descriptions with each log
entry.
Each tray of drill core is photographed (wet and dry) after it is fully marked
up for sampling and cutting.
The total length and percentage of
the relevant intersections logged.
Diamond drilling
All drill holes (Flynn Gold and historic) are logged in full and to the total
length of each hole.
Subsampling
techniques
and sample
preparation
If core, whether cut or sawn and
whether quarter, half or all core
taken.
Core is sampled using half of the HQ diameter. The drill core is cut with a
diamond saw and the orientation line is retained.
If non-core, whether riffled, tube
sampled, rotary split, etc and
whether sampled wet or dry.
Rock-chip and channel samples were collected dry.
No other sub-sampling techniques such as riffle splitting were utilised.
Channel samples were collected directly from exposed outcrop using a
hammer and chisel, with the entire sample submitted to the laboratory.
For all sample types, the nature,
quality and appropriateness of the
sample preparation technique.
The sample preparation for all samples follows industry best practice.
Diamond drilling
Entire samples were prepared at the Onsite laboratory in Bendigo. Sample
preparation is minimal, after drying and weighing the sample is crushed
to a top-size of 2-3mm then between 400-650g is placed in a barcoded jar
for photon analysis.
Quality control procedures adopted
for all subsampling stages to
maximise representivity of samples.
Sampling is guided by Flynn’s protocols and Quality Control procedures,
as per industry standards.
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.
Diamond drilling
Sampling representivity is maximised by always taking the same side of
the drill core (whenever orientated), and consistently drawing a cut line
on the core where orientation is not possible.

Criteria JORC Code explanation Commentary
All competent core was cut with an automated core saw. Fragmented or
broken core was cut using a hand operated saw to minimise sample loss
and maintain representative sampling.
Sampling intervals ranged from 0.2m to 1.0m. Intervals shorter than 1.0m
were used where discrete geological features – such as quartz veins, faults
or lithological boundaries – were present. The sample sizes are
considered appropriate for the nature of mineralisation.
Coarse rejects and lab-splits of mineralized zones are retained for
potential further QAQC analysis, including check assaying at an
independent laboratory.
Whether sample sizes are
appropriate to the grain size of the
material being sampled.
Photon assay samples were 300g to 3kg before sample prep.
Rock chip and channel samples were 300g to 3kg before sample prep.
200-500g of soil is collected for UFF analysis, which is considered
appropriate for the analysis technique.
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.
Photon assay for Au (Diamond drilling)
Photon assay is a recently developed method of gold analysis developed
by the CSIRO. The analysis by high-energy X-rays is a non-destructive
method therefore the original sample can be retained for further analysis
(compared to Fire Assay where the sample is destroyed during analysis).
Sample preparation and photon assay is performed by Chrysos at the
Onsite Laboratory in Bendigo (PAAU002). It is an industry recognized
method for gold analysis.
Multi Element ICP-MS (Diamond drilling)
Samples were prepared at Onsite laboratory in Bendigo for multi-element
assay by 4 acid digest (BM040)
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.
No geophysical tools were used to determine any element concentrations
Nature of quality control procedures
adopted (e.g. standards, blanks,
duplicates, external laboratory
checks) and whether acceptable
levels of accuracy (i.e. lack of bias)
and precision have been
established.
Flynn Gold has its own internal QAQC procedure involving the use of
certified reference material (CRM) standards, blank (non-mineralised)
materials, and duplicate samples.
If CRM or blank results were outside of the accepted error margin the
sample batch is re-run (fully or partially).
External laboratory checks have not been used to date.
Diamond Drilling
For diamond drilling standards (Certified Reference Material) and blanks
are inserted every 20 samples.
OREAS Certified Reference Material (CRM) includes anomalous grade (<1
g/t Au), low grade (<4 g/t Au), mid-range (>4 and <10 g/t Au), high grade
(>10g/t) and very high grade (>40g/t). The CRM inserted into the sample
sequence was based on expected gold grades from visual mineralogy and
texture.
Standards and blanks passed within an acceptable level of precision and
accuracy.
If CRM or blank results were outside of the accepted error margin the
sample batch is re-run (fully or partially).
External laboratory checks have not been used to date. Pulps and
laboratory splits have been retained for future laboratory checks.
The Onsite laboratory conducted laboratory splits and laboratory CRM’s
at a regular frequency.

Criteria JORC Code explanation Commentary
Laboratory duplicates were taken for intervals where higher gold grades
were expected, based upon visual mineralogy and texture.
A total of eight laboratory duplicate sample pairs were reviewed. Relative
Percent Difference (RPD) values range from 0% to ~83%, with an average
of ~24% and a median of ~20%. Duplicate precision is strongly grade-
dependent. Very low-grade samples (<0.1 g/t Au) show generally good
repeatability, with low absolute differences despite moderate percentage
RPD values. Low- to moderate-grade samples (0.1–2 g/t Au) exhibit more
variable precision, including one elevated RPD value (~83%), consistent
with the coarse and locally nuggety nature of gold mineralisation. Higher-
grade samples (>1.5 g/t Au) demonstrate excellent repeatability, with RPD
values typically ≤2%. The observed variability is considered consistent
with expected nugget-effect behaviour in early-stage, vein-hosted gold
systems and does not indicate analytical bias.
Internal laboratory QAQC checks are reported by the laboratory (Onsite
Bendigo). On going review of the internal laboratory QAQC suggests the
laboratory is performing within acceptable limits.
Verification
of sampling
and assaying
The verification of significant
intersections by either independent
or alternative company personnel.
All reported data was subjected to validation and verification by company
personnel prior to reporting.
The use of twinned holes. Twinned holes have not been drilled at Double Event.
