________________________________________________________________________________
Horizon Gold Limited (ASX : HRN) (Horizon or Company) is pleased to announce significant gold
intercepts returned from diamond drilling at its 100% owned Gum Creek Gold Project (Gum Creek or
the Project) located in the Mid-West Region of Western Australia. Final assay results for four of the
seven holes drilled at the Kingfisher Prospect have been received (Figure 1).
Managing Director Scott Williamson said:
“The diamond drilling results at Kingfisher are delivering exactly what we hoped for – and more. We've
confirmed our gold mineralisation model while unlocking significant down-plunge extensions that
weren't captured in previous resource estimates. With assays still pending from remaining holes,
Kingfisher is shaping up to be substantially larger than initially envisaged. Combined with ongoing
drilling at Omega, we're building a strong newsflow pipeline as we systematically unlock the
underground potential across the Gum Creek Project.”

The Kingfisher prospect is located 3.5km south-southeast of the Gidgee Mill and hosts a current open
cut MRE of 1.22Mt @ 2.01g/t Au for 78,900oz and an underground MRE of 1.04Mt @ 3.38g/t Au for
113,500oz (Table A).
The Company completed seven diamond holes including one daughter hole at the Kingfisher prospect
for a total of 3,745.2m. The Kingfisher drill program aimed to test high priority targets down plunge of
previous high grade drill intercepts including 15m @ 28.5g/t Au from 346m and 10m @ 8.9g/t Au from
190m1
. Assays received from the first four holes have confirmed and extended previously identified
high-grade gold mineralisation down plunge to the north of the resource block model (Figures 2 & 3).
Numerous significant intercepts were returned (Table A) including:
▪ 3m @ 2.79g/t Au from 350m (KFDD003)
▪ 4m @ 11.35g/t Au from 431m including 1m @ 42.2g/t Au from 432m (KFDD003)
▪ 18m @ 1.09g/t Au from 469m including 10m @ 1.57g/t Au from 473m (KFDD003)
▪ 5m @ 1.59g/t Au from 529m including 2m @ 3.51g/t Au from 529m (KFDD005)
▪ 16m @ 1.17g/t Au from 431m including 4m @ 2.64g/t Au from 438m (KFDD007)

Gold mineralisation at Kingfisher is located within several moderately southwest-dipping, planar gold
lodes within a 60m wide, 1.2km long shear zone that remains open to the north, south and at depth.
Both lodes are interpreted to contain moderately south plunging high grade gold shoots forming part
of a large en-echelon vein array that steps down to the north.
KFDD007 successfully intersected sheared, quartz-veined, strongly sericite–carbonate–fuchsite
altered volcaniclastic schist units between 423m and 456m, confirming the presence of a third
interpreted mineralised gold shoot approximately 150m down plunge to the north of existing drilling.
This newly defined shoot has the potential to contribute significant additional ounces to the Kingfisher
gold resource.
Further deep infill and extensional diamond drilling has been planned, with Programs of Work (POW’s)
approved. Upcoming drilling will focus on increasing resource confidence within the known high-grade
plunging shoots, while also targeting additional resource ounces within the newly identified high-grade
mineralised shoot intersected in KFDD007.

Omega Deep Diamond Drilling Progress
Three of the deep diamond holes at the Omega prospect have been completed to date for a total of
1271.4m with the fourth hole now underway. The Omega program is testing for extensions to high-
grade mineralisation beneath impressive previous drill intercepts including 30m @ 21.1g/t Au from
57m and 13m @ 10.8g/t Au from 122m2
. All assays are pending.
Feasibility Study Progress and Resource Expansion Drilling
The Company is focused on completing the free milling Feasibility Study and highlighting the potential
for developing a significant stand-alone gold operation at Gum Creek. Work on the Feasibility Study is
progressing well. Metallurgical, geotechnical, processing, waste rock, tailings and soil landform reports
have been received, all environmental and heritage surveys have been completed, surface water
infrastructure designs, pit and waste rock dump designs and mine infrastructure designs have been

completed, and water management plans and water balance modelling are almost complete. The
Study remains on schedule for completion H1 CY 2026.
The Company believes the Gum Creek Gold Project will be a robust, viable stand‐alone mining
operation with the recent high gold prices only strengthening the March 2024 Scoping Study outcomes3
and providing a high level of confidence for the current Feasibility Study outcomes.

APPENDIX 2: JORC TABLE 1 (SECTIONS 1 AND 2)
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 done 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.
• HQ3 and NQ2 diamond core was drilled to various depths using a truck-
mounted DRA 800 diamond drill rig.
• Selected diamond core was cut in half using an on-site Almonte
diamond saw and sampled at 1m intervals over mineralised intervals
selected by the supervising geologist.
• Sampling was undertaken using Horizon Gold Limited (HRN) sampling
protocols and QAQC procedures in line with industry best practice, with
laboratory standard reference material, sample blanks and sample
duplicates inserted/collected at every 25th sample in the sample
sequence.
• Half core diamond samples were submitted to Australian Laboratory
Services (ALS) in Perth for preparation (including pulverising) to
produce a 50g sub-sample for analysis for gold by 50g Fire Assay.
Pre-2014 Drillholes
• Diamond drilling involved HQ3 and NQ2 core. Sampling of diamond
core involved 1m sampling, with sampling over geological intervals
(down to 0.1m) in more recent holes. The diamond core has generally
been cut in half for sampling with some holes whole core sampled, and
some quarter core sampled subsequent to half core sampling where
alternate laboratory samples were submitted or thin section work was
completed.
• Initially assaying utilised the aqua regia process but most assays used
in this report have been by fire assay with an AAS finish using the site
laboratory or off-site laboratories. A 50g charge was generally used.
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).
• Diamond core was drilled from surface to facilitate geotechnical logging
and sampling from surface. Industry standard barrels and triple tube
barrels were used to obtain HQ3 and NQ2 core samples.
• Diamond core holes were routinely surveyed for down hole deviation
using a DeviGyro set to collect continuous readings every 5m down
each hole.
• HQ3 and NQ2 core was orientated using Reflex orientation tools, with
core initially cleaned and pieced together at the drill site. Core was then
reconstructed into continuous runs on an angle iron cradle for down hole
depth marking and then orientated with orientation lines marked up by
HRN field staff at the Gidgee Core Shed.
Pre-2014 Drillholes
• Diamond drilling was completed with industry standard diamond drill
rigs acquiring HQ (63.5mm) or NQ (47.6mm) diamond core with a
standard tube and all core oriented whenever possible.
• Only some of the pre-2014 diamond core was oriented and some
orientation marks have since faded or disappeared.

Criteria JORC Code explanation Commentary
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.
• Diamond drillers measure core recoveries for every drill run completed
using either three or six metre core barrels. The core recovered is
physically measured by tape measure and the length is recorded for
every “run”. Core recovery is calculated as a percentage recovery. Core
recovery is confirmed by Horizon field technicians and geologists during
core orientation activities on site and recorded into the database.
• Various diamond drilling additives (including muds and foams) were
used to condition the drill holes and maximise recoveries and sample
quality.
• There is no significant loss of material reported in the mineralised parts
of the diamond core intercepts reported.
• The diamond core sample recovery and quality is considered to be
adequate for the drilling technique employed.
Pre-2014 Drillholes
• Diamond core recovery was noted during the drilling and geological
logging process as a percentage of core recovered vs. expected drill
length.
• There is no evidence of there being sample bias due to non-
representative or preferential sampling.
• No apparent relationships were noted in relation to 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.
• 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 diamond drill holes were geologically logged by a qualified Geologist.
• Qualitative and quantitative geological logging recorded colour, grain
size, weathering, oxidation, lithology, alteration, veining and
mineralisation including the abundance of specific minerals, veining,
and alteration using an industry standard logging and geological coding
system.
• Structural measurements of foliation, shearing, faulting, veining,
lineations etc. (using a kenometer to collect alpha and beta angles) were
collected for all diamond core. These measurements were then plotted
down drill traces in 3D software to aid geological interpretations and
modelling of gold mineralisation.
• Rock Quality Designation (RQD) measurements are completed on all
diamond core.
• All diamond core is photographed in the core tray in both dry and wet.
Pre-2014 Drillholes
• All historical drill holes have been logged using the various company
logging codes. The type of drill log varies with time depending on drill
technique, year and company.
• Logging included codes and descriptions of weathering, oxidation,
lithology, alteration and veining.
• Geological logging is qualitative and based on visual field estimates.
• Not all diamond core logs have been converted to a digital format.
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.
• Core samples were cut in half using an auto feed Almonte diamond core
saw. Half core samples were collected for assay except duplicate
samples which are quarter core. All remaining core is retained and
stored in core trays on site.
• Sample preparation was undertaken by ALS Perth.
• At the laboratory, samples were weighed, dried and crushed to -6mm.
The crushed sample was subsequently bulk-pulverised in an LM5 ring
mill to achieve a nominal particle size of 85% passing <75um.
• Sample sizes and laboratory preparation techniques are considered to
be appropriate for the commodity being targeted.
Pre-2014 Drillholes
• DD has involved HQ and NQ core sizes. Sampling of diamond core has
involved 1m sampling, with sampling over geological intervals (down to
0.1m) in more recent holes. The diamond core has generally been cut
in half for sampling however some holes are whole core sampled and
some quarter core sampled or quarter core sampled subsequent to half

thin section work was completed.
• Where it has been suspected that drillholes were drilled down dip,
scissor holes have been drilled.
• Most drilling showed good sample recovery with the exception of some
holes drilled in 1989. There is no stated evidence of there being sample
bias due to preferential sampling. There is no relationship between
sample recovery and grade.
• Sample sizes and laboratory preparation techniques are considered to

factors applied and their derivation,
etc.
• 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
• Analysis for gold only was undertaken at ALS Perth using 50g Fire
Assay with AAS finish to a lower detection limit of 0.01ppm. Fire assay
is considered a “total” assay technique.
• No geophysical tools or other non-assay instrument types were used in
the analyses reported.
• Review of routine standard reference material and sample blanks
suggest there are no significant analytical bias or preparation errors in
the reported analyses.
• Results of analyses from field sample duplicates are consistent with the
style of mineralisation being evaluated and considered to be
representative of the geological zones which were sampled.
• Internal laboratory QAQC checks are reported by the laboratory.
• Review of the internal laboratory QAQC suggests the laboratory is
performing within acceptable limits.
Pre-2014 Drillholes
• Initially, assaying utilised the aqua regia process but most assays
referred to in this report have been by fire assay with an AAS finish using
the site laboratory or off-site laboratories. A 50g charge was used. After
2000, samples were assayed at the Gidgee accredited mine-site
laboratory using the Leachwell method with approximately 30g of
sample pulverised to 85% passing -200 mesh. The analytic techniques
are considered appropriate. Where coarse gold occurred, offsite screen
fire assaying was carried out using a 105 micron sieve.
• Samples were submitted to off-site laboratories with check assays
carried out in 1988. Further check assays were carried out in other years
however this data has not been analysed. Some CRMs and blank
samples were used prior to 2002 however there is insufficient
information to complete an accurate analysis. There are records of
laboratory standards and blanks having been submitted post 2002 and
an analysis of these shows good correlation between results. No
evidence has been found in the mining process that there were issues
with assaying. An analysis of duplicates showed that in general the
precision of samples was adequate.
Verification of
sampling and
assaying
• 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.
• All diamond core geological logging and sampling data were recorded
in the field in hard copy form, and subsequently data entered into Excel
spreadsheets.
• Assay results are merged with sampling data using established
database protocols run in house by HRN.
• Digital data (Excel spreadsheets) were uploaded into a relational
database and validated by experienced database personnel and
geological staff. Plans, cross sections and long sections were
generated, and visual validation was completed in 3D (Micromine) as
further quality control.
• Twin holes were not utilized to verify results; however, some infill
verification holes were completed to test the strike continuity of
mineralisation. Virtually all drilling confirmed expected geological and
mineralogical interpretations.
• The deposits are reasonably continuous in terms of mineralisation and
grade. The continuity and consistency of the grade intercepts down dip
and along strike give reasonable confidence in the verification of the
grade and style of deposit.

• All historic reported data has been reported in technical reports
submitted by previous tenement holders to the Western Australian
Government which are now available as open file.
• No adjustments were made to assay data except for replacing less than
detection limit values with negative detection limit numerical values.
• All significant intersections reported have been compiled and reviewed
by senior geological personnel from the Company.
Location of data
points
• 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.
• Drill hole collar locations were determined using GDA94 Zone 50
coordinates and datum.
• Drill hole collars were positioned and picked up on hole completion
using a Carlson BRx7 DGPS (GDA94 Zone 50). DGPS eastings,
northings and RL’s have been used for all RC and diamond hole collars.
• Diamond core holes are routinely surveyed for down hole deviation
using a DeviGyro set to collect readings every 5m down each hole.
• The topography at all prospects drilled is flat, however 3D topographic
surfaces or Digital Terrain Models (DTMs) were built using a
combination of mine surveyor pickups, drill hole DGPS RL pickups, RL’s
from specifically selected DGPS points and LiDAR data.
• Locational accuracy at the collar and down the drill hole is considered
appropriate for this stage of exploration and for resource estimation
work.
Pre-2014 Drillholes
• Planned drill hole locations were positioned by either hand-held global
positioning satellite (GPS) in AMG84 or GDA94 zone 50 datums or
pegged on local grids by a mine surveyor and transformed to GDA94
coordinates. The majority of holes have subsequently been picked up
by DGPS and were generally found to be within 1m horizontal and 1m
vertical accuracy.
• Historic drilling coordinates include both local, AMG84 and GDA94
coordinates. The Company database contains all sets of coordinates,
but for the purpose of this report the GDA94 grid coordinates have been
used. All coordinates are reported in GDA94 – Zone 50 grid datum.
• The topography at Kingfisher is flat apart from waste dumps.
• All drill collars were displayed in Micromine and visually checked against
the DTMs. The DTMs were created using a combination of surveyed pit
and waste dump pickups, DGPS pickups of historical and more recent
drill hole collars, and specifically selected DGPS pickup points. RL data
bias or error is considered low given the flat topography reported.
• Down-hole surveys were routinely performed every 5m to 30m using a
range of single shot, electronic multi-shot
