SKY Managing Director & CEO Oliver Davies commented: “With tin and silver prices reaching record highs, this is
an outstanding time to be reporting such impressive early results from our ongoing multi‑rig drilling program at
Tallebung. Tin has surged above US$53,000/t on the LME – more than four times the copper price – highlighting
the exceptional value of high‑grade tin discoveries such as this.
“The high-grade intercepts from the southern and central parts of the deposit reinforce Tallebung’s status as a
premier near‑term development opportunity, particularly against the backdrop of rising tin, silver and tungsten
prices. We look forward to receiving further assay results in the coming weeks as drilling continues with multiple
rigs, and to advancing the Project rapidly toward potential tin‑silver‑tungsten production.”

Sky Metals Limited (ASX: SKY) is pleased to report exceptionally high‑grade tin and silver assay results from the
first batch of drilling completed as part of the ongoing multi‑rig drilling program at the Company’s 100%-owned
Tallebung Tin Project in central western New South Wales.
TALLEBUNG TIN PROJECT (EL 6699, SKY 100%)
TALLEBUNG RC DRILLING CONTINUES TO INTERSECT SHALLOW, HIGH-GRADE TIN-SILVER ZONES
The ongoing multi‑rig drilling program at the Tallebung Tin Project continues to deliver strong results, with the first
batch of assays returning multiple shallow, high‑grade tin, silver and tungsten intercepts across several emerging
zones of the expanding deposit.
In particular, drill-hole TBRC268 has confirmed strong potential along the southern extent of the Tallebung deposit,
where the mineralisation remains open along strike. This hole highlights the presence of persistent high‑grade
silver‑tin mineralisation in this area, extending beyond the limits of the current Mineral Resource outline, with
intercepts including:
TBRC268: 5m @ 103g/t Ag & 0.30% Sn from 76m
This result reinforces the opportunity for further shallow high‑grade discoveries to the south, with further drilling
being planned to step-out along strike and test for additional extensions of this emerging high‑grade extension.
These results continue to validate SKY’s strategy of accelerating drilling across newly identified high‑grade zones
to support a significant upgrade to the Tallebung Mineral Resource Estimate (MRE) in the first half of 2026.
The current drilling program is designed to systematically expand high‑grade mineralisation beyond the margins
of the existing MRE while simultaneously strengthening geological confidence through targeted in-fill drilling.
With assays now received for more than 20 drill holes, a further 40 holes already completed and awaiting results,
and additional drilling planned in the coming months, SKY is rapidly building the extensive exploration and
technical datasets required to support mine design, geotechnical modelling and feasibility‑level studies.
ONGOING DRILLING AND NEXT STEPS
More than 400 drill holes are expected to be incorporated into an updated MRE (compared to just 115 holes in the
existing MRE. The expanded and higher‑confidence MRE to be released over the coming months will form the
foundation for updated open‑pit designs, mine scheduling and ongoing metallurgical and environmental studies.
The combination of high-grade intercepts, shallow geometry, large-scale RC coverage, and new structural data
positions Tallebung as a standout near‑term tin development project capable of delivering significant scale and
exceptionally strong metallurgical performance – as already demonstrated through SKY's bulk ore sorting and
gravity testwork programs.
UPDATED MRE AND MINING STUDIES ON TRACK
The updated MRE remains on schedule for release in the first half of this year and is expected to incorporate data
from more than 400 drill holes, a substantial increase from the 115 holes used in the existing MRE.
This expanded dataset is anticipated to deliver a significant upgrade in both resource size and confidence levels,
supporting the ongoing mining study workstreams.

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.

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.
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.
For RC drilling, assay standards or blanks are inserted at least every 50 samples.
All sample lab received weights show consistency with 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.
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. Where mineralisation has not been logged, 4m Composites have been made by using
a spear to Combine equal amounts of samples from each 1m calico.
The primary metal of interest, tin (Sn) and also tungsten (W) were determined by lithium borate fusion
XRF (method ALS – ME-MS85) – considered appropriate for these elements. Multielement assaying was
completed for 48 elements by 0.25g four-acid digest with ICPMS determination (method ALS – ME-
MS61) or for infill holes, assay of Ag, As, Cu, Pb, Zn with ICP determination (method ALS – ME-ICP61)
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 drilling - high capacity RC rig was used to enable dry samples collected. Drill cyclone is cleaned
between rod changes and after each hole to minimise cross-hole contamination.
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.
10
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.
RC chips, half core (HQ) & ¾ core (PQ) samples are retained in trays for future reference.
A representative sample of each one metre RC interval is retained in chip trays for future reference.
All chips were geologically logged.
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
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. Where 4m Composites have been made, a spear is used to split equal amounts of
each metre into the 4m Composite.
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 50 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.
RC drilling - duplicate samples are collected of re-split intervals. Duplicates generally show excellent
repeatability.
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), were undertaken. Forty-eight
elements Ag, As, Cu, Fe, Pb, S, Zn are digested by four-acid digest then analysed by ICPMS (method ME-
MS61) or for infill holes, assay of Ag, As, Cu, Pb, Zn with ICP determination (method ALS – ME-ICP61)
Sn and W assays were generated by lithium borate fusion XRF (method ME-MS85) – considered
appropriate for these elements.
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

Criteria Explanation Commentary
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, Ag 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
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
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
considered well understood and consistent.

Sample security • The measures taken to ensure sample security Sample chain of custody has been managed by the employees of Sky Metals who Commissioned the
drilling and transport samples from the drilling rig to assay laboratory.
All samples are bagged in tied numbered calico bags, grouped into larger tied polyweave bags, or placed
in a stillage box and transported to ALS in Orange by SKY personnel. All sample submissions are
documented via ALS tracking system and all assays are reported via email.
Sample pulps are returned to site and stored for an appropriate length of time (minimum 3 years). The
Company has in place protocols to ensure data security.
