INITIAL RESOURCE GROWTH DRILLING RETURNS HIGH-GRADE TIN-
TUNGSTEN-SILVER AT TALLEBUNG
• Major 150+ hole drilling program underway, targeting resource growth and increased
Measured and Indicated Resources to support potential mine-life extensions
• First assay results received from new diamond drilling program identifying new shallow,
wide and high-grade tin-tungsten-silver mineralisation, including:
TBD022: 17m @ 0.70% Sn, 0.03% WO₃ & 14.8g/t Ag from 26m, including:
- 4m @ 2.44% Sn, 0.06% WO₃ & 28.0g/t Ag from 28m
• These results add to significant shallow, high-grade tin-tungsten-silver mineralisation
identified since the recent MRE cut-off, highlighting strong potential for further resource
growth for future mine-life extensions at Tallebung.
• Latest diamond drilling has intersected coarse wolframite-hosted¹ tungsten mineralisation,
with assays pending, highlighting favourable mineralogy for processing, while testing along
strike and adjacent to previously intercepted high-grade tungsten mineralisation, including:
TBRC218: 6m @ 1.66% WO3, 0.10% Sn & 20.2g/t Ag from 21m; and:
10m @ 0.76% WO3, 0.10% Sn & 80.6g/t Ag from 53m
• Drilling is also planned to commence shortly at the Theirman Mines Prospect, targeting
high-grade tungsten mineralisation identified in recent rock-chip sampling, which returned
assays of up to 7.44% WO₃ across more than 500m of prospective strike.
SKY Managing Director & CEO Oliver Davies commented: “These latest results provide further evidence of the
significant growth potential we see at Tallebung, with another broad, shallow and high-grade tin intercept adding
to the growing inventory of significant mineralisation identified since the cut-off for our recent Mineral Resource
Estimate update.
“The identification of coarse wolframite (tungsten) in our latest diamond drilling is also an encouraging
development for Tallebung. Combined with the high-grade tungsten already intersected nearby, this highlights the
potential for tungsten to become an increasingly important part of the Tallebung story. The coarse nature of the
tungsten mineralisation intersected further highlights the exceptionally favourable mineralogy of the deposit and
its amenability to simple, low-cost processing, adding to the processing advantages already demonstrated for the
coarse cassiterite (tin) mineralisation.

In relation to the disclosure of visible mineralisation, the Company cautions that visual estimates of mineral abundance should never be
considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest.
Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. The
Company will update the market when laboratory analytical results become available, expected from October 2026.

“With our PFS establishing a clear development pathway for Tallebung, we have now commenced a major new
150-hole drilling program targeting further resource growth and potential mine-life extensions.
“At the same time, we are preparing to drill the high-grade tungsten targets at Theirman Mines, just 20km away.
Together with resource growth drilling at Tallebung, pending assays from the remaining diamond drill-holes and
upcoming drilling at Theirman, this continues the exciting period for SKY as we continue to demonstrate both the
quality and growth potential of Tallebung and the potential of the broader Tallebung region.”

Sky Metals Limited (ASX: SKY) (“Sky Metals” or the “Company”) is pleased to report new shallow, high-grade tin-
tungsten-silver results from its recent diamond drilling program at the 100%-owned Tallebung Tin- Tungsten -
Silver Project in NSW. The recent drilling has also intersected coarse wolframite-hosted tungsten mineralisation
in at least two diamond holes, with laboratory assays pending.
The latest results come as SKY commences a major new Reverse Circulation (RC) drilling program comprising
more than 150 RC holes targeting further growth in the Tallebung Mineral Resource to support future potential
mine life extensions.
In parallel, the Company is preparing to drill test the new Theirmans Mines high-grade tungsten-tin-gold prospect,
located approximately 20km from Tallebung, with drilling set to commence in the coming weeks.
TALLEBUNG PROJECT (EL 6699, SKY 100%)
DIAMOND DRILLING RETURNS NEW HIGH-GRADE TIN-TUNGSTEN-SILVER INTERCEPTS
The latest drilling results continue to demonstrate the significant growth potential of the Tallebung Tin-Tungsten-
Silver Project as SKY advances the Project towards development. The first assay results from the recent diamond
drilling program have returned further broad, shallow and high-grade tin-tungsten-silver mineralisation, while
visual observations of coarse wolframite in separate diamond holes provide an encouraging indication of the
potential for additional tungsten-rich mineralisation, with assays for these intervals pending.
The first results have now been received for the latest diamond drilling program, including hole TBD022 which
returned:
TBD022: 17m @ 0.70% Sn, 0.03% WO₃ and 14.8g/t Ag from 26m, including;
4m @ 2.44% Sn, 0.06% WO₃ and 28.0g/t Ag from 28m.
The shallow depth, width and grade of this intercept reinforce the continuity and quality of the mineralisation being
defined at Tallebung and add further drilling information to expand the substantial mineralised system already
established at the Project.
Importantly, recent drilling continues to identify significant mineralised positions that were not included in the
latest Mineral Resource Estimate (MRE). These include:
TBRC427: 9m @ 0.54% Sn, 0.14% WO₃ and 205g/t Ag from 67m, including;
1m @ 2.45% Sn and 1.11% WO₃ from 75m.
TBRC468: 1m @ 5.45% WO₃ and 0.08% Sn from 66m, and;
3m @ 1.16% Sn, 0.19% WO₃ and 10.6g/t Ag from 75m.
These results form part of an expanding body of post-MRE drilling that highlights opportunities to further grow and
enhance the Mineral Resource in future updates.

The growing contribution from tungsten and silver alongside tin is particularly encouraging. Recent drilling has
demonstrated locally very high tungsten grades as well as significant silver mineralisation.
The diamond drilling is also crucial in providing geological and structural information that can improve SKY's
understanding of the controls on these higher-grade mineralised positions and assist the targeting of future drilling
as well as vital for ongoing geotechnical studies for the open pit mine designs.
COARSE WOLFRAMITE HIGHLIGHTS FURTHER TUNGSTEN POTENTIAL
The recognition of coarse wolframite-hosted tungsten in the latest diamond drilling is a very important
development which highlights how amenable the Tallebung mineralisation is to simple processing given the
incredibly favourable coarse wolframite-hosted tungsten mineralogy at Tallebung.
This is a particularly encouraging development from the newly completed 12-hole diamond program with the
identification of coarse wolframite-associated tungsten mineralisation in at least two drill holes. Assay results are
eagerly anticipated for these new intercepts.
MAJOR RESOURCE GROWTH DRILLING UNDERWAY
With the recent PFS establishing a development pathway for Tallebung, SKY has now commenced a major new
RC drilling program comprising more than 150 planned holes. The program is designed to systematically test
opportunities for additional resource growth and potential mine-life extensions while development activities
continue in parallel.
This next phase of drilling represents a progression from the successful drilling campaigns completed over the
past 18 months to continue SKY’s successful growth of the Mineral Resources at Tallebung. These programs
progressively expand the known mineralised footprint and identify new shallow, high-grade tin-tungsten-silver
positions, this includes a growing inventory of mineralisation identified after the cut-off date for the latest MRE
(ASX Announcement 13 July 2026).
The scale of the new program therefore provides a significant opportunity to test how much additional
mineralisation can be defined beyond the resource base used in the recent development studies. In particular,
further shallow mineralisation has the potential, subject to successful drilling, resource estimation and subsequent
mine planning, to provide additional development optionality through resource growth and potential mine-life
extensions.
THEIRMAN MINES DRILLING TO PROVIDE ADDITIONAL EXPLORATION UPSIDE
In parallel with the major Tallebung drilling program, SKY is preparing to drill test the Theirman Mines Prospect,
where recent surface sampling returned exceptional tungsten grades of up to 7.44% WO₃ and confirmed more
than 500m of prospective strike across at least two mineralised trends. These results also validate historical high-
grade sampling from the area and have rapidly advanced Theirman to drill-ready status.
Importantly, Theirman Mines represents a new, high-grade exploration opportunity rather than simply an
extension or analogue of the Tallebung deposit. Its location approximately 20km from Tallebung nevertheless
provides a significant operational advantage, allowing SKY to undertake initial drill testing using exploration
personnel, contractors and infrastructure already operating in the area.
Together, the major resource-growth program at Tallebung, pending assays from the recently completed diamond
drilling and near-term drill testing at Theirman provide SKY with a substantial pipeline of drilling and exploration
catalysts while the Company continues to advance Tallebung along its development pathway towards future tin-
tungsten-silver production

About the Tallebung Tin-Tungsten-Silver Project (100% SKY)
Tallebung is an advanced tin-tungsten-silver development project in central western New South Wales. A
recently completed Pre-Feasibility Study outlined robust, high-margin economics, low development capital
requirements and a pathway to first production in 2028, while utilising only part of the current Mineral Resource.
Ongoing drilling continues to expand the deposit and identify new high-grade tin, tungsten and silver zones
beyond the current resource, including the drill testing of the new proximal Theirman Mines Prospect 20km
north of the Tallebung site with high-grade tungsten up to 7.44% WO₃ from surface rock chip results.
Bulk sampling and pilot-scale metallurgical testwork at Tallebung have successfully demonstrated a low-cost
processing pathway combining ore sorting and conventional gravity recovery, reinforcing Tallebung's potential
to become a significant new Australian producer of tin, tungsten and silver and an important future supplier of
critical minerals to global technology, electrification and defence markets.

JORC CODE, 2012 - TABLE 1
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.
Drill core sampling is by sawn quarter core PQ & half core HQ core. Nominal sample intervals are 1m with
a range from 0.3m to 2.0m.
All samples were submitted to SGS or ALS Orange for preparation and assaying.
• Include reference to measures taken to ensure sample representivity and the appropriate
calibration of any measurement tools or systems used.
For diamond drilling standards are insert every 30-50 samples.
All sample lab received weights show consistency with core recovery and interval length.
• 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.
Diamond drilling - core samples were taken at nominally 1m, but with a range between 0.3-2m. PQ core
samples are cut in quarters with ¾ retained for reference and metallurgical test work and ¼ submitted
for assay - dried, crushed and pulverised to 90% passing 75 microns.
ALS Orange - Forty-eight elements including Ag, As, Cu, Fe, In, Pb, S, Zn are digested by four-acid digest
then analysed by ICPMS (method ME-MS61). Sn and W assays were generated by lithium borate fusion
XRF (method ME-MS85) – considered appropriate for these elements and by XRF fusion for +1% ore
grade assays.
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)
Diamond Drilling completed by drilling PQ. PQ was drilled to approx. 150m to produce the largest
sample then cased down to HQ.
PQ and HQ core was orientated.
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 weights are recorded for each sample. Recoveries were generally excellent and consistent,
however, if samples were wet the recoveries were less consistent.
There is no known relationship between sample recovery and grade. Where samples recoveries are less
than 95% there is no relationship observed between grade and sample recovery. Relationships between
sample recovery and grade are not considered significant where recoveries exceeded 95% in fresh rock.
11
Criteria Explanation Commentary
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
Systematic geological and geotechnical logging was undertaken when the holes were originally drilled.
Data collected includes:
• 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.
Half core (HQ) & ¾ core (PQ) samples are retained in trays for future reference.
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
Drill core sampling is by sawn quarter core PQ & half core HQ core. Nominal sample intervals are 1m with
a range from 0.3m to 2.0m.
Samples were dried crushed and pulverised to 90% passing 75 microns. This is considered to
appropriately homogenise the sample to allow subsampling for the various assay techniques.
SKY: Certified Reference Material (CRM) and blanks were inserted at least every 30 samples to assess the
accuracy and reproducibility of the drill core results. The results of the standards were to be within ±10%
variance from known certified result. If greater than 10% variance the standard and up to 10 samples
each side were re-assayed. SGS conducted internal check samples every 20 for multielement assay.
Sample sizes are industry standard and considered appropriate
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 - Forty-eight elements
including Ag, As, Cu, Fe, In, Pb, S, Zn are digested by four-acid digest then analysed by ICPMS (method
ME-MS61). Sn and W assays were generated by lithium borate fusion XRF (method ME-MS85) –
considered appropriate for these elements and by XRF fusion for +1% ore grade assays.
No geophysical tools were used in the determination of assay results.
Certified reference material or blanks were inserted at least every 50 samples. Standards are purchased
from Certified Reference Material manufacture companies: Standards were purchased in foil lined
packets of between 60g and 100g. Different reference materials were used to cover high grade, medium
grade, low grade, and trace ranges of elements, with a primary focus on Sn and W.
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 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.
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

Criteria Explanation Commentary
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.
W is converted to WO3 for reporting via multiplication of WO3/W or 231.84/183.84 = ~1.2611 factor to
provide assays as WO3. Other 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
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.
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. 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
At this stage, drilling of the MRE area of the project has been drilled to at least approximately 80m x 80m
down to 40m x 40m for inferred and indicated resources respectively. Outside of the MRE are, data
spacing is variable as the focus is on geological mapping and identifying new zones of mineralisation.
The maiden MRE was estimated to inferred and indicated and increases in resource confidence will
require tighter spaced drilling, such as some of the drilling completed in this program.
Sample Compositing is not applied.
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 sampling bias, this should be assessed and reported
if material
Drilling was orientated to cross the mineralisation trend at moderate to high angles, perpendicular to
mineralisation. The use of orientated core allows estimates of the true width and orientation of the
mineralisation to be made accurately.
No sample bias due to drilling orientation is known. The structural controls on mineralisation is
