4m @ 0.80% tin from 16m.
TBRC127:
32m @ 0.23% tin from 65m, including:
1m @ 2.23% tin from 65m, and
2m @ 0.73% tin from 73m, and
3m @ 0.59% tin from 84m.
TBRC139:
24m @ 0.24% tin from 6m, including:
6m @ 0.42% tin from 11m.
TBRC140:
18m @ 0.24% tin from 42m, including:
4m @ 0.60% tin from 50m.
• Results significantly expand the deposit to the east and west, demonstrating Tallebung
remains open in all directions and higher grades continuing to be discovered off the margins
of the existing MRE.
• Results will continue over the coming months as the current drilling program targets further
shallow extensions and continues infill of the existing Tallebung MRE.
• Assay results received for only 25 holes of the 75 holes completed to date, with a further 85
approved holes remaining to be drilled in the coming months.
SKY Managing Director & CEO Oliver Davies commented: “The SKY geological team has done a brilliant job in
discovering extensions to the existing deposit, particularly in delivering these new, shallow, broad and highergrade zones beyond the eastern margin of the existing Resource.
“The tin price is maintaining strong levels, trading over 3 times the copper price, demonstrating the high value
nature of the near-surface tin delineated in this latest drilling. We look forward to reporting the next batches of
results over the coming weeks as we continue to progress through this exciting ongoing drilling program.”

Sky Metals Ltd (ASX: SKY) (‘SKY’ or the ‘Company’) is pleased to report the second 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
Additional extensions to the Tallebung deposit have been encountered in the second batch of assay results from
the large, ongoing Reverse Circulation (RC) drilling program. The results expand the central part of the deposit to
both the east and west, demonstrating that the deposit remains open in all directions (see Figure 1).
The latest batch of RC holes (TBRC119-131) were designed to infill and expand known zones of mineralisation at
the southern end of the existing deposit (Figure 1). The results have confirmed higher-grade zones and identified
that the deposit extends to the west and east of this existing zone and remains open.

mineralisation intercepted near surface and on the eastern margin of the existing MRE, open to the east, down
dip and along strike. NB: Depth scale on RHS border in metres from surface.

This southern area has been an important focus of the RC drill campaign because this zone is likely to be targeted
in the early stages of a future mining operation to extract higher-grade, shallow tin mineralisation to facilitate a
rapid capital payback.
Hole TBRC132 was drilled approximately 150m west of the existing Tallebung MRE, with this hole successfully
intercepting tin mineralisation and demonstrating that the deposit remains open to the west.
Holes TBRC133 - TBRC140 were completed beyond the eastern margin of the existing MRE at Tallebung. Results
from this area significantly expanded the deposit and include a number of high-grade, shallow intercepts such as
12m @ 0.39% tin from 16m, including 4m @ 0.80% tin from 16m in hole TBRC138. Further drilling has already been
planned in this area to build on these excellent, early results.
The new tin mineralisation intercepted on the eastern margin of the deposit provides further extensions of shallow,
higher-grade mineralisation that can be incorporated into the early stages of the mine plan to bolster the
Company’s goal of achieving a fast payback of project CAPEX.
Excellent progress continues to be made in the ongoing drilling program, with a total of 75 holes completed to date.
Approvals have now been received to substantially expand the drilling program, with a further approximately 80
holes now planned in addition to the initial 70 holes, increasing the overall program to approximately 150 holes.
The additional 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.
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.

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.

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.

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.

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 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.
