DRILLING EXPANDS GOLD SYSTEM SOUTH OF CHICKEN LITTLE AT
YIRILGEE
HIGHLIGHTS
➢ New drilling confirms and expands gold mineralisation at the T8 target within the
Yerilgee Project. Significant intercepts include:
o 5m @ 1.38 g/t Au from 97m, including 2m @ 2.95 g/t Au and 1m @ 4.65 g/t Au
(26YGRC007)
o 8m @ 0.59 g/t Au from 109m, including 3m @ 0.95 g/t Au (26YGRC005)
o 3m @ 1.23 g/t Au from 33m (26YGRC008)
➢ T8 lies ~14 km south of Chicken Little, where recent drilling returned 48m @ 2.61 g/t Au
from 15m¹, confirming multiple mineralised centres along the Yerilgee corridor.
➢ Gold mineralisation is hosted in both BIF and mafic rocks, demonstrating a broader
mineralised system.
➢ Most of the Yerilgee corridor remain untested, highlighting significant exploration
upside.
➢ Results form part of Catalina’s 8,694m Phase 1 drilling campaign, with all assays remain
pending from Chicken Little.
Catalina Resources Limited (ASX: CTN) is pleased to report recently received assay results from drilling
at the T8 target within the Yerilgee Project, part of the Company’s Central Yilgarn Project in Western
Australia.
The T8 target lies approximately 14km south of Chicken Little, where recent drilling returned 48m @ 2.61
g/t Au from 15m¹.
The results confirm and expand gold mineralisation at T8, demonstrating continuity of the system along
strike and across multiple host lithologies within a major regional structural corridor.
Together, the results confirm that the Yerilgee structural corridor hosts multiple mineralised centres over
a distance exceeding 14 km, highlighting the district scale potential of the Central Yilgarn Project.
Executive Director, Ross Cotton, commented:
“These results from T8 show that Yerilgee is continuing to grow as a significant gold corridor.
T8 was already recognised as a strong target, and this drilling has now confirmed and expanded the gold
system, while also showing that mineralisation is hosted in both BIF and surrounding mafic rocks.
With mineralisation now confirmed at both Chicken Little and T8, we are seeing multiple gold centres
emerging along the samestructural corridor.Largeportions of this trend remain effectively untested, and

with further assays still pending from the Phase 1 program we believe Yerilgee is evolving into a
significant new gold camp in the Central Yilgarn.”
PHASE 1 CAMPAIGN MOMENTUM
These results form part of Catalina’s Phase 1 drilling program, comprising 8,694 metres of RC and
Aircore drilling completed across the Central Yilgarn Project.
They follow the recently reported assays from the Chicken Little prospect, which returned 48m @ 2.61
g/t Au from 15m1
. Additional assay results from Chicken Little and other targets across the project
remain pending.
Figure 1. Yerilgee Target Location and Project Geology
T8 Prospect
The T8 prospect was originally identified as a priority drill target based on coincident gold-in-soil
geochemistry, favourable banded iron formation (BIF) host rocks and a regional structural corridor.
Historical exploration2
defined a coherent gold anomalous zone associated with a folded BIF sequence
intruded by felsic porphyry (figure 2), interpreted to represent a favourable structural setting for gold
mineralisation. Previous drilling intersected several zones of gold mineralisation including2
:
➢ 27m @ 0.6 g/t Au from 6m, including 2m @ 2.2 g/t Au and 1m @ 9.0 g/t Au
➢ 17m @ 0.7 g/t Au from 22m, including 8m @ 1.2 g/t Au from 27m
➢ 10m @ 0.8 g/t Au from surface, including 1m @ 6.0 g/t Au from 11m

Figure 2. T8 Camp Historical Results and Project Geology
Following acquisition of the project, Catalina completed an independent technical review of the Central
Yilgarn Project, which confirmed the prospectivity of several targets including Chicken Little, Snowflake,
Megatron and T83
. The review highlighted the Yerilgee area as a large-scale structural corridor hosting
multiple BIF-related gold targets, with T8 ranked among the highest priority targets for drilling.
Collectively, these results defined a clear mineralised corridor, and the current drilling was designed to
test and refine this zone (figure 3).
Catalina’s drilling program was designed to test this mineralised corridor and confirm the presence of
gold mineralisation within the T8 target zone.
CATALINA 2026 RESULTS
Results reported here relate to drilling completed at the T8 Prospect.
Assay results from T8 have expanded the known mineralised footprint by testing the northern and
southern extents of the anomaly, confirming that gold mineralisation continues along strike and occurs
in multiple host lithologies within the same mineralised system.
Multiple drill holes have intersected gold mineralisation across the central portion of the anomaly,
demonstrating the presence of a coherent mineralised system rather than isolated intercepts. The
coincidence of mineralised drill intersections with strong soil gold anomalies and magnetic features
validates the Company’s exploration targeting model and highlights additional untested zones along the
corridor.
In the northern portion of the prospect, drilling intersected gold mineralisation hosted within magnetite-
bearing BIF (figure 3), where higher grades coincide with the core of the magnetic high and soil gold
anomaly (figure 5). Results included:
o 5m @ 1.38 g/t Au from 97m, including 2m @ 2.95 g/t Au and 1m @ 4.65 g/t Au (26YGRC007)
o 8m @ 0.59 g/t Au from 109m, including 3m @ 0.95 g/t Au (26YGRC005)
o 3m @ 1.23 g/t Au from 33m (26YGRC008)

IMPLICATIONS FOR SYSTEM SCALE AND EXPANSION
Rather than identifying an isolated new occurrence, Catalina’s drilling has expanded the known gold
mineralisation at T8 and demonstrated that the broader Yerilgee corridor hosts multiple mineralised
centres over significant strike length.
Together with the recently reported results at Chicken Little, these results materially advance the
Company’s understanding of the emerging gold system at Yerilgee.
Key observations from the results reported to date include:
➢ Multiple mineralised centres identified along the Yerilgee corridor, with gold confirmed at
both Chicken Little and T8 approximately 14 km apart.
➢ Gold mineralisation confirmed across multiple lithologies, including BIF-hosted
mineralisation at T8 and structurally controlled mineralisation in mafic units, indicating a
broader hydrothermal system.
Page 7
➢ Meaningful widths and locally elevated grades intersected at T8, demonstrating continuity of
mineralisation across several drill holes rather than isolated intercepts.
➢ Strong correlation between drilling, soil geochemistry and magnetic features, validating the
exploration targeting model across the project area.
➢ Mineralisation confirmed well beyond Chicken Little, demonstrating the potential for a
continuous gold system developing along the Yerilgee structural corridor.
➢ Large portions of the interpreted mineralised corridor remain untested, including magnetic
features and soil anomalies extending beyond current drill coverage.
➢ Further assays pending from additional holes at Chicken Little and other targets from thePhase
1 drilling program.
Collectively, these results support the interpretation of Yerilgee as an emerging gold corridor within the
Central Yilgarn Project, with multiple mineralised centres and significant potential for further discoveries
and system expansion along strike and at depth as exploration continues.
NEXT STEPS
With Phase 1 drilling now completed, Catalina is rapidly advancing interpretation across the emerging
Yerilgee gold corridor as further assay results are received.
The Company is integrating geological, geochemical and geophysical datasets to refine the mineralised
model and prioritise follow-up drilling designed to extend the system along strike and at depth.
Importantly, several untested magnetic and soil gold anomalies remain along the Yerilgee corridor, many
of which share similar geological characteristics to both the Chicken Little and T8 prospects.
With multiple mineralised centres now confirmed over a 14 km corridor and further assays pending from
Chicken Little and other targets, Catalina expects the next phase of work to continue defining the scale
and continuity of this emerging gold system within the Central Yilgarn Project.

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
mineralization 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 mineralization types (eg
submarine nodules) may warrant
disclosure of detailed information.
Catalina Resources completed 9 RC holes
drilled totalling 11580m at the T8 prospect
Central Yilgarn project over the period 21
January to 30 January 2026.
Drilling was supervised and samples
collected by geologists from Apex
Geoscience which is an independent
geological consultancy.
Drill samples were collected by Reverse
Circulation (RC) drilling. Drill hole details
are provided in Appendix 1.
RC drilling was used to obtain 1m samples
using a Sandvik Static Cone Splitter in
calico bags and weighing 2 to 3 kg each.
Samples were delivered to the ALS Lab in
Kalgoorlie (for photon assay).
The samples were analysed using the
photon assay method which uses a 0.5kg
sample and requires minimal handling. The
samples are riffle split at the lab and
crushed to 80% passing 2mm to ensure
homogeneity as uniform sample distribution
is important to a quality analysis.
The samples are considered to effectively
represent the drilling at the point of
collection. Sampling included Catalina
Resources standard QAQC procedures.
Quality control of the assaying comprised
the collection of a duplicate samples every
hole, along with regular insertion of industry
(Geostats) standards (certified reference
material) and (certified reference material)
and blanks.
Drilling
techniques
• Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc) and details (eg core
diametre, 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).
length drill rods with automatic rod
handlers.
Holes were drilled at an angle of -60⁰. An
8x8-mounted Schramm 685 RC drill rig,
supported by a Mercedes 8x8 booster truck,
a Sullair 900/1150 auxiliary compressor and
a Hurricane 1000-psi booster, was used to
complete the drilling program. RC drilling
produces dry rock chips, as large capacity
air compressors dry the rock out ahead of
the advancing drill bit. Downhole Surveys
employed a downhole Gyro making readings
every 5m. The rig was supported by a
primary compressor rated at approximately
900 CFM at 300 PSI.
Downhole Surveys employed a downhole
Gyro making readings every 5m.
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.
Sample recovery was assessed visually via
the sample size collected into the calico
bags. Where sample recovery was low due
to wet samples material was scooped from
the spoil pile.
Sample recovery and condition was noted
for every metre.
Ground water caused wet samples
occasionally, so splitting of the sample was
not possible.
In ground sumps were dug prior to drilling
commencing, to collect the excess
groundwater expelled by the rig.
Catalina Resources does not anticipate any
sample bias from loss/gain of material from
the drill rig cyclone.
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.
RC drill holes were logged for various
geological attributes, including colour,
lithology, oxidation, alteration,
mineralisation and veining. All holes were
logged in full by geologists from Apex
Geoscience.
No geotechnical logging was possible as the
RC drilling method does not allow RQD
recording.
Geological logging was qualitative at 1m
intervals and was recorded at the sample
depth.
Representative 1m samples weighing 20 gms

Criteria JORC Code explanation Commentary
were collected and placed into plastic chip
trays for later reference.
The recording was done at a level
commensurate with the early stage of
exploration.
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.
N/A
Dry and wet drill samples were collected at
the drill collar. After passing through the
sample hose and into the drill cyclone the
samples pass through a riffle splitter to
homogenise the sample and to nullify the
effects of particulate gold. After splitting, the
sample was collected in a calico bag, ready
for assaying.
The samples are considered to effectively
represent the rock at the point of collection.
Sampling included Catalina Resources
standard QAQC procedures. Quality Control
on the RC drill rig included insertion of
duplicate samples to test lab repeatability,
insertion of standards to verify lab assay
accuracy and cleaning and inspection of
sample assembly. A standard or duplicate
was inserted every 20th to 25th sample.
The sample sizes and analysis size are
considered appropriate to correctly represent
the mineralisation based on the style of
mineralisation, sampling methodology and
assay value ranges for the commodities of
interest.
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.
• 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.
All samples were delivered to the ALS Labs in
Kalgoorlie for Photon Assay. Photon assay
method has shown to provide quick turn
around times and high accuracy.
The assay method and laboratory procedures
were appropriate for this style of
mineralisation. The fire assay technique for
the RC chips were designed to return precise
precious metal recoveries.
The ALS lab inserts its own standards and
blanks at set frequencies and monitors the
precision of the analyses. As well, the lab
performs repeat analyses at random
intervals, which return acceptably similar
values to the original samples.
Page 14
Criteria JORC Code explanation Commentary
Laboratory procedures are within industry
standards and are appropriate for the
commodities of interest.
Industry certified Geostats standards were
inserted in the RC chip sample stream every
25 samples, and field duplicates were
collected every 20 samples.
The samples are considered to effectively
represent the rock at the point of collection.
Sampling included Catalina Resources
standard QAQC procedures.
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.
Consultant geologists, from Apex
Geoscience, were involved in the logging of
the RC drilling. Apex was involved in the
whole process including drill hole
supervision, chip sample collection and
importing of the completed assay results.
Drill hole logs were inspected to verify the
correlation of mineralized zones between
assay results and
lithology/alteration/mineralisation. The entire
chain of custody of this recent drilling was
supervised by Apex Geoscience.
The drill hole data was logged in a locked
excel logging template and then stored in a
Micromine database structure for long term
storage and validation.
Data was reported by the laboratory and no
adjustment of data was undertaken.
All assay results were verified by alternative
company personnel and the Qualified Person
before release.
Analysis of the accuracy of the above QAQC
procedures needs to be within acceptable
limits.
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.
RC drill hole locations were picked up using a
handheld Garmin GPS, considered to be
accurate to ± 5 m.
Downhole surveys have been completed at 5
m stations (and start and end of hole) using a
downhole gyroscopic survey tool.
All coordinates were recorded in MGA Zone
51 datum GDA94.
Page 15
Criteria JORC Code explanation Commentary
Topographic control is provided by a Digital
Terrain Model based on the 90 m Shuttle
Radar Topographic Mission data.
Drill hole details are in Appendix 1 of this
announcement.
Data spacing
and
distribution
• 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 holes were sited in a position to
intercept the previously identified air core
mineralisation, aiming to obtain grade and
width information.
The orientation of the mineralisation is not
yet defined, at this stage of exploration.
N/A as no resource estimate is made.
No compositing has been conducted.
Orientation
of data in
relation to
geological
structure
• Whether the orientation of sampling
achieves unbiased sampling of possible
structures and the 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.
Appendix 1 tables the MGA coordinates, of
each hole.
RC drilling is a hammer percussion
technique to shatter the rock and does not
allow rock structures to be seen.
Drilling is assumed to intersect the
mineralised structures at right angles. 9
holes were drilled at -60 degrees to the west.
Until Catalina ascertains all assays back or
conduct diamond drilling, Catalina is
uncertain of the geometry of the mineralised
structures.
Sample
security
• The measures taken to ensure sample
security. Drill samples were placed into calico bags
measuring 14 in x 12 in. They were then
placed into larger poly weave bags which
were sealed with cable ties.
Large bulka bags were used to transport
these poly weave bags to the ALS lab in
Kalgoorlie.
A sample submission outlining assay
instructions was provided to ALS.
ALS maintains the chain of custody once the
samples are received at the laboratory, with
a full audit trail available via the ALS
website.
Page 16
Criteria JORC Code explanation Commentary
The chain of custody for samples from
collection to delivery at the laboratory was
handled by Apex Geoscience personnel.
Audits or
reviews
• The results of any audits or reviews of
sampling techniques and data. At this stage of exploration, no external
audit or review has been undertaken.
The work was carried out by reputable
companies and laboratories using industry
best practice.
