:
–
• New high-grade, shallow tin intercepts from ongoing Reverse Circulation (RC) drilling further
enhance the scale and tenor of the Tallebung deposit, with results including:
TBRC153:
15m @ 0.68% tin & 77.2g/t silver from 64m, including:
5m @ 1.22% tin & 219g/t silver from 72m.
TBRC159:
20m @ 0.41% tin from 8m, including:
8m @ 0.66% tin from 8m.
TBRC151:
12m @ 0.56% tin from 58m, including:
4m @ 1.04% tin from 58m.
• Results demonstrate the deposit remains open in all directions, while adding new high-grade
zones within the existing MRE.
• More results will be released over the coming months as the drilling program continues to
target shallow extensions and infill the existing Tallebung MRE.
• Assay results now received for 45 of the 93 holes completed to date, with a further 60
approved holes remaining to be drilled in the coming month.
SKY Managing Director & CEO Oliver Davies commented: “These excellent results provide new, high-grade zones
that will continue to grow our Resources at Tallebung, with these intercepts both expanding and improving the
Tallebung deposit. They reinforce Tallebung’s credentials as an ultra-low-cost potential source of tin supply
thanks to the unique nature of the mineralisation being well-suited to open pit mining and very low-cost
processing.
“Tin continues to trade at more than three times the copper price, accentuating the high-value nature of the nearsurface tin being delineated in this drilling program. Results will continue to flow over the coming months as the
drilling continues, building on the great success the program has already delivered to date.”
Sky Metals Ltd (ASX: SKY) (‘SKY’ or the ‘Company’) is pleased to report the third batch of assay results from the
large Reverse Circulation (RC) drilling program that commenced in mid-April at its flagship 100%-owned Tallebung
Tin Project in central NSW.
TALLEBUNG PROJECT (EL 6699, SKY 100%)
EXTENSIVE RESOURCE GROWTH-FOCUSED RC DRILLING PROGRAM
Assay results for the third batch of samples from ongoing RC drilling at the Tallebung deposit have returned new,
high-grade intercepts in the central area of the deposit, while also expanding the deposit to the east and north.
The deposit continues to remain open in all directions (see Figure 1).

Figure 1: Plan showing the location of the drill-holes in the latest program, including new assay results, new
extensional drill-holes with assays pending, and selected previously reported highlight drill intercepts. The
boundary of the existing Tallebung MRE is also shown over surface geology.
The latest batch of RC holes (TBRC141-160) were designed to expand the deposit beyond the north-eastern end of
the existing MRE and infill areas of known shallow, high-grade mineralisation.
Drilling successfully discovered shallow extensions to the deposit well beyond the north-eastern margin of the
existing MRE. This demonstrates the deposit remains open and also presents an exciting area to target further
mineralised extensions beyond these drill holes to continue to expand the deposit footprint.
Infill drilling of the south-central zone of the deposit, south and adjacent to the southern open pit, represents a
vital step to increase confidence in the existing MRE. Infill holes have successfully intercepted higher than
anticipated grades of tin in this zone, identifying additional shallow, higher-grade mineralisation, which is likely to
be targeted in the early stages of a future mining operation to facilitate rapid capital payback.

The major drilling program continues to rapidly progress, with 91 holes completed to date. A further approximately
60 holes are approved to be drilled over the coming month, with the overall program of approximately 150 holes to
be completed in the next month.
Figure 2: Cross-section of TBRC152 and TBRC153 with previous drilling, showing the shallow dipping
mineralisation near-surface and mineralised vein packages are projected onto the section. Where no intercepts
are shown in the section, the vein packages have been projected from adjacent intercepts. NB: Depth scale on
LHS border is metres from surface.
The remaining holes are designed to further explore the extensions of the Tallebung deposit as new zones continue
to be discovered. Significantly, many of the new zones are located in areas away from historical workings,
suggesting that the best parts of the deposit may be yet to be found. Assays are pending for more than 45
completed holes, with approximately 60 holes yet to be drilled.
A steady stream of results is expected over the next few months as the drilling programs advance. The Company
will continue to provide regular updates as assay results are received.
This announcement is authorised for release by the Board of Sky Metals Limited.

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 semiconductors, 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.

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.

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.

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.
