• Follow‑up drill holes to test these new extensional targets already permitted and approved
and will be integrated into the current multi‑rig program.
• Approvals pathway advancing, with the NSW State Significant Development (SSD) process
initiated, the Scoping Report commenced and environmental consultants engaged.
• New Environmental Manager appointed to support Executive Director Scott Todd,
accelerating approvals activities and positioning Tallebung for near‑term development.
SKY Managing Director & CEO Oliver Davies commented: “These latest results continue to reinforce the
outstanding growth potential of our shallow, high‑grade tin-tungsten-silver system at Tallebung. The confirmation
of high‑grade mineralisation both in drilling and at surface provides clear opportunities for near‑term resource
growth.
“With the State Significant Development process now underway and a dedicated environmental team in place,
our approvals work is advancing rapidly, in parallel with ongoing drilling and technical studies. With two rigs
turning and follow‑up holes already approved, we continue to progress both expansion and in-fill drilling to support
the upcoming Mineral Resource update and advance Tallebung toward development readiness.”

Sky Metals Limited (ASX: SKY) is pleased to advise that new high‑grade results from drilling and surface sampling
have further expanded the mineralised footprint of the Company’s flagship Tallebung Tin Project in
central‑western NSW.
TALLEBUNG TIN PROJECT (EL 6699, SKY 100%)
TALLEBUNG CONTINUES TO GROW
Ongoing Reverse‑Circulation (RC) drilling continues to intersect thick, shallow and high‑grade tin-tungsten-silver
mineralisation across multiple areas of the deposit, while new rock‑chip assays have confirmed significant
high‑grade tin mineralisation at surface to the south, extending the known system along strike.
Standout drilling results include TBRC317, TBRC296, TBRC304 and TBRC302, which collectively demonstrate both
grade and thickness at depths amenable to open‑pit development. These results build on earlier programs that
identified high‑grade positions on the deposit margins, reinforcing the open‑ended nature of the Tallebung system
and its capability to deliver material Resource growth.
SOUTHERN EXTENSION CONFIRMED AT SURFACE
Tin‑cassiterite-bearing rock chips grading up to 1.35% Sn (GC20260107‑2) and 1.10% Sn and 18.2g/t Ag
(GC20260107‑1) have been collected from newly identified historical workings south of the current Resource
envelope. These results have confirmed the continuity of mineralisation at surface and highlight additional
high‑priority targets for immediate drill testing.
Follow‑up drill holes are permitted and approved, ready to be drilled, and will be added to the current multi‑rig
drilling schedule.

drill‑hole intercepts. The surface positions of historical workings are also displayed, with the mineralisation
hosted in stacked vein packages that extend to surface, trending towards these historical workings. Note: faults
strike obliquely to the section, and some drill holes lie off section centre, which may limit the precision of
representing the geology in two dimensions.

The current exploration program continues to proceed with strong momentum at Tallebung with two RC rigs
operating continuously, as SKY systematically advances both extensional and in-fill drilling to:
1. Expand newly defined high‑grade zones along strike and down‑dip; and
2. Complete the in-fill coverage required to support the upcoming Mineral Resource Estimate (MRE) and
mine planning.
Geological logging, structural interpretation and growing geotechnical datasets from the program are feeding
directly into mine design and mining studies, keeping the development workstreams closely aligned with
exploration.

APPROVALS & PERMITTING UPDATE – SSD PROCESS INITIATED
SKY has initiated the NSW State Significant Development (SSD) approvals process for Tallebung, with
environmental consultants engaged to prepare and submit the Scoping Report in the coming months. The Company
has also appointed a new Environmental Manager to support Executive Director Scott Todd and the leadership
team, ensuring dedicated capacity to coordinate baseline studies, community and stakeholder engagement, and
to advance the Environmental Impact Statement (EIS) work program on schedule.
The initiation of the SSD process represents an important milestone that runs in parallel with SKY’s multi‑rig
drilling, metallurgical testwork and mine design activities. This integrated approach is designed to compress
timelines between exploration success, resource growth and development readiness.
Work is now underway to integrate these new target areas into the active drilling schedule, ensuring that both
extensional and in-fill drilling components progress simultaneously. The significant datasets being generated –
5
including detailed geological logging, structural interpretation, and expanding geotechnical coverage – will
directly feed into ongoing mine design, mining studies and metallurgical modelling, maintaining SKY’s strong
momentum toward development readiness.
NEXT STEPS
– Integrate permitted follow-up drill holes testing the southern rock-chip targets into the current multi-rig
program.
– Continue RC step-outs and in-fill across high-grade tin-tungsten-silver positions to support the upcoming MRE
update.
– Continue building geotechnical and structural data collection (from diamond, geotechnical holes as required)
to advance mine design.
– Progress SSD approvals workstreams: SEARs, specialist baseline studies, EIS scope and schedule, and
community engagement.
– Provide progressive assay updates as results are received.

About the Tallebung Tin Project (100% SKY)
Tallebung stands as an open-pit, technology enabled, near-term tin development project. Tallebung is uniquely
placed to provide secure tin supply, to feed irreplaceable and rapidly expanding tin demand, essential in semi-
conductors, electronics and solar PV technologies.
The Tallebung Tin Project is located at the site of large-scale historical tin mining in central Western NSW
where tin was first discovered in the 1890s. SKY is progressively defining a large-scale hardrock tin resource
with recent higher-grade tin zones discovered on the margins of the known deposit and exceptional
metallurgical performance demonstrated across the entire known deposit.
The shallow, open-pit tin veins combined with the ideal nature of the tin, hosted as large, discrete grains of
simple tin-oxide (cassiterite minerals), all ideally lends itself to low-cost tin production advantages, including
exceptional X-ray based ore sorting performance, demonstrated to upgrade the tin up to 44x, prior to low-cost
gravity separation to produce a saleable tin concentrate.

Section 1 Sampling Techniques and Data – TALLEBUNG PROJECT
(Criteria in this section apply to all succeeding sections)
Criteria 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.
Rock chips and grab samples taken with a geological hammer and collected into labelled calico bags.
All samples were submitted to ALS Orange for preparation and assaying
Soil samples were collected from holes approximately 15cm in depth and sieved to 100% passing 2mm, a
50-100g sample was collected for assay and analysis via pXRF.
RC Drilling – the total sample (~20-30kg) is delivered via cyclone into a large plastic bag which is retained
for future use if required. 1m intervals are split using a cone splitter on the rig into a separate calico at
the time of drilling.
• Include reference to measures taken to ensure sample representivity and the appropriate
calibration of any measurement tools or systems used.
Soil samples were initially sent for assay via standard assay procedures performed by a reputable assay
lab, (ALS Orange). Multielement assaying was completed for 48 elements by 0.25g four-acid digest with
ICPMS determination (method ME-ICP61). Sn & W were analysed at ALS via ME-MS85 by lithium meta-
borate fusion and ICP-MS. Overlimit samples are analysed via ME-XRF30 fusion.
Laboratory assays were the assessed with in-field pXRF analysis via an Olympus Vanta pXRF handheld
device. Results were found to be sufficiently comparable for the purposes of soil sampling.
Subsequent soil sampling results were obtained via handheld Olympus Vanta pXRF analysis and these
results are report herein.
• 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information.
Each sample was dried, crushed and pulverised as per standard industry practice.
Rock chip and RC drilling samples were dried, crushed and pulverised to 90% passing 75 microns –
assays are pending.
Soil samples analysed via handheld Olympus Vanta pXRF.
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)
Reverse circulation (RC) drilling using 110mm rods, 144mm face sampling hammer.
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
RC samples were weighed for each metre and assessed for recovery, contamination and effect of water if
present. Sample quality is assessed by the sampler by visual approximation of sample recovery and if the
sample is dry, damp or wet. A high capacity RC rig was used to enable dry samples to be collected. Drill
cyclone is cleaned between rod changes and after each hole to minimise cross-hole contamination.

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
Samples were geologically described at the time of collection. The descriptions were of sufficient detail to
support the current work.
All rock chips and soil samples were described at the time of collection.
Both qualitative and quantitative data is collected. All rock chips and RC chip trays were digitally
photographed.
Systematic geological logging was undertaken, with data collected including:
• Nature and extent of lithologies.
• Relationship between lithologies.
• Amount and mode of occurrence of ore minerals.
• Location, extent, and nature of structures such as bedding, cleavage, veins, faults etc.
Structural data (alpha & beta) are recorded for orientated core.
• Geotechnical data such as recovery, RQD, fracture frequency, qualitative IRS, microfractures,
veinlets and number of defect sets. For some geotechnical holes the orientation, nature of
defects and defect fill are recorded.
Both qualitative and quantitative data is collected for all RC drilling.
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
No field duplicates are taken for the rock chip samples. The sample was crushed and pulverised to 90%
passing 75 microns. This was considered to appropriately homogenise the sample.
The available data suggests that sampling procedures provide sufficiently representative subsamples for
the current interpretation.
RC drilling - the total sample (~20-30kg) is delivered via cyclone into a large plastic bag which is retained
for future use if required. 1m intervals are split using a cone splitter on the rig into a separate calico at
the time of drilling.
RC samples were dried, crushed and pulverised to 85% passing 75 microns. This is considered to
appropriately homogenise the sample to allow subsampling for the various assay techniques.
Duplicates are taken for RC samples.
Sample sizes are industry standard and considered appropriate.
Soil samples were collect from 1015cm deep hand dug holes and sieved to -2mm before 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
• 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
Standard assay procedures performed by a reputable assay lab, (ALS Orange), were undertaken.
Multielement assaying was completed for 48 elements by 0.25g four-acid digest with ICPMS
determination (method ME-ICP61). Sn & W were analysed at ALS via ME-MS85 by lithium meta-borate
fusion and ICP-MS. Overlimit samples are analysed via ME-XRF30 fusion.
Handheld pXRF was used in the determination of soil sampling assay results.
Internal laboratory checks confirm assay precision and accuracy with sufficient confidence for the
current results. Certified Standards and blanks are used in RC drilling and soil sampling assaying.

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
Drill and surface sampling data is compiled and collated and reviewed by senior staff. External
consultants do not routinely verify exploration data until resource estimation procedures are deemed
necessary. The intersection calculations were viewed by >1 geological personnel.
Assay data was provided by ALS via .csv spreadsheets or downloaded from handheld Olympus Vanta
pXRF and compiled by SKY Geologists.
Twinned holes have been used by past explorers to validate the results achieved and have confirmed
these historic results.
Drill Hole Data including: meta data, any gear left in the drill hole, lithological, mineral, survey, sampling,
magnetic susceptibility was collected and stored as physical and electronic copies or entered directly into
an excel spread sheet using drop down codes. When Complete the spreadsheet was Combined into a
master excel spreadsheet as the drill hole database.
Assay data was provided by ALS via .csv spreadsheets. The data was validated using the results received
from the known certified reference material. Hard copies of the assay certificates were stored with drill
hole data such as drillers plods, invoices, and hole planning documents.
Assay data is not adjusted.
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
SKY has used handheld GPS to locate rock chip & soil sample locations (nominal accuracy ± 5m).
All coordinates are based on Map Grid Australia Zone 55E, Geodetic Datum of Australia 1994.
Historic drill hole collars were located using either a licenced surveyor or on a local imperial or metric
grid. Conversion of the local grid co-ordinates has been undertaken by previous exploration Companies.
SKY has used DGPS surveying of drillholes (± 0.1m) to accurately locate them.

Historic drill hole collars were located using either a licenced surveyor or on a local imperial or metric
grid. SKY has used DGPS surveying of drillholes (± 0.1m) to accurately locate them, or handheld GPS (+/-
3m). Where handheld GPS has been used, SKY will DGPS them at a later date.
Data spacing and
distribution
• Data spacing for reporting of Exploration Results
• 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
Soil sampling conducted on close spacing is based on geological knowledge of the deposit and due to the
proximity of a large known Resource, hence, it has been determined to select very close space sampling
to aid in best targeting of follow up work as the body of the ASX Announcement support, this has results
in the success in identifying further potential mineralisation in the drilling logs provided.
At this stage, drilling of the MRE area of the project has been drilled to at least approximately 80m x 80m
