FURTHER EXPANSIONS OF TIN MINERALISATION
AND HIGH-GRADE TIN INTERCEPTED AT TALLEBUNG
Two groundwater monitoring bores have been completed to commence the mine
permitting process at Tallebung and were drilled outside of a ‘conceptual open pit’ and
over 140m from any previous drilling.
One of these groundwater bores intercepted strong tin mineralisation, results include;
TBRC072:
18m @ 0.12% Tin from 14m, including;
1m @ 1.27% Tin & 0.03% Tungsten from 24m.
These results significantly expand the footprint of the tin mineralisation at Tallebung.
Outcropping quartz veins approximately 200m from the current extent of drilling have
been discovered with visible cassiterite-tin*, rock chip samples have been collected
- Assays are pending for these samples.
Additionally, assay results for 3 of the 4 diamond drillholes completed in the Resource
Expansion Program for a total of 947.8m show high-grade tin mineralisation; results
include;
TBD005:
13m @ 0.48% Tin from 2m, including;
1m @ 3.18% Tin from 11m.
TBD006:
2.4m @ 2.88% Tin & 0.07% Tungsten from 28.8m, including;
1m @ 7.73% Tin & 0.17% Tungsten from 29.65m
TBD007:
4.1m @ 0.50% Tin & 0.06% Tungsten from 33m, and;
2.5m @ 1.35% Tin & 0.04% Tungsten from 82.5m
Results of the Resource Expansion Program have now been provided to SKY’s
resource geologists at H&SC. An updated MRE is expected imminently.
* 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 late-December 2023.

The Board of Sky Metals Limited (‘SKY’ or ‘The Company’) is pleased to announce the following exploration results
which substantially expand the extents of the known tin mineralisation at the at the Tallebung Project.
TALLEBUNG PROJECT (EL 6699, SKY 100%)
RESOURCE EXTENSIONS
Two groundwater monitoring bores were drilled to commence recording data for mining and environmental
permits to progress the Tallebung Tin Project. The bores were designed to be drilled well outside of any known tin
mineralisation and outside of any potential future open pit area.
One of these groundwater monitoring bores intercepted strong tin mineralisation which substantially expands the
extents of the tin mineralisation at Tallebung; results include:
TBRC072:
18m @ 0.12% Tin from 14m, including;
1m @ 1.27% Tin & 0.03% Tungsten from 24m.
This hole was drilled over 140m further west from the nearest drillhole, adding over 140m of width to the 300-400m
wide mineralisation discovered at Tallebung.
In addition to this substantial extension, quartz veining with visible cassiterite nuggets has also been discovered
in the base of the historic central lead open pit where alluvial tin resources were extracted in the 1960s - 1970s.
Three rock chip samples, OD20231020-1 – OD20231020-3, have been taken of these outcrops and assays are
pending for these samples (Figure 2 & Table 3).
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 late-December 2023.
RESOURCE EXTENSION DIAMOND DRILLING
All holes were completed by early October for a total of 4 holes for 947.8m, holes TBD005-TBD008. All holes
intercepted the characteristic coarse cassiterite-hosted tin mineralisation at Tallebung and assay results have
now been received for 3 of the 4 holes completed, TBD005-TBD007.
TBD005 was drilled to target tin lodes at depth and intercepted strong veining with visible coarse cassiterite
(Figure 1). TBD005 intercepted three (3) tin lodes, beginning at the top of the hole from 2m DH. Results included:
TBD005:
13m @ 0.48% Tin from 2m, including;
1m @ 2.01% Tin from 5m, and;
1m @ 3.18% Tin from 11m.
7m @ 0.18% Tin, 0.37% Tungsten & 11.4g/t Silver from 51m.
26.1m @ 0.10% Tin from 206.9m, including;
1m @ 0.70% Tin & 0.04% Tungsten from 215m, and;
5m @ 0.22% Tin from 228m

Figure 2: Tallebung Tin Project – Rock chip samples pictured next to the outcropping quartz veins sampled.
TBD006 was then drilled on the southern extent of the maiden MRE near hole TBRC042 (11m @ 0.81& Tin from
27m). TBD006 intercepted very coarse cassiterite demonstrating the consistent nature of the tin mineralisation at
Tallebung as being hosted in coarse cassiterite, results included:
TBD006:
2.4m @ 2.88% Tin & 0.07% Tungsten from 28.8m, including;
1m @ 7.73% Tin & 0.17% Tungsten from 29.65m
TBD007 targeted down dip and along strike extensions to the strong tin mineralisation intercepted in the vicinity
of TBRC034 (43m @ 020% Tin from 5m). Multiple high-grade lodes were intercepted, results included:
TBD007:
4.1m @ 0.50% Tin & 0.06% Tungsten from 33m, and;
2.5m @ 1.35% Tin & 0.04% Tungsten from 82.5m
TBD008 was then drilled to test extensions to tin mineralisation in the north of the central area of the Tallebung Tin
Mining Field (Figure 1 and 2).
These holes were also logged for detailed geotechnical studies to aid in future mine planning and mine open pit
designs for any future mining excavation. These diamond drillholes are being drilled with wide diameter PQ drill
core to over 150m downhole to provide material for bulk samples for further representative metallurgical testing.
These holes have now also been sampled for metallurgical testwork which will aim to improve on the current
simple processing methods available for the Tallebung mineralisation due to the coarse nature of the cassiterite4
hosted tin. The samples have already been delivered to TOMRA Ore Sorting to confirm, and possibly improve, the
excellent results achieved to date showing a low-cost processing pathway for the Tallebung tin mineralisation.
UPDATED MINERAL RESOURCE ESTIMATE
All assays for the RC drilling component of the resource expansion program and the diamond drilling assays
received to date have now sent to SKY’s resource geology consultants at H&SC. These new results will be
included in a new Mineral Resource Estimate (MRE). This will aim to increase SKY’s maiden MRE of 10.2Mt @
0.18% Tin for 18.4kt at a 0.10% Tin cut-off grade and convert the estimated Exploration Target of 16 – 21Mt at a
grade ranging between 0.16 - 0.20 % tin at 0.1% Tin cut-off, into additional resources (SKY ASX Announcement
22 March 2023).
Following the new estimate of the mineral resources at Tallebung, if required, SKY plans to undertake an
additional drilling program to increase confidence in the resources, in particularly resources around high-grade
areas such as those identified surrounding hole TBD003 (60.55m @ 0.36% Tin from 23m), increasing the resource
confidence in these areas to indicated resources. The surrounding resource is planned to be drilled to inferred
resources and this aims to achieve a ‘critical mass’ for mine scoping studies to be undertaken and released.

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 SGS 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.

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 SGS in Orange by SKY personnel. All sample submissions are
documented via SGS 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.
Audits or reviews
The results of any audits or reviews of sampling techniques and data
The Company does not routinely have external consultants verify exploration data until resource
estimation procedures are deemed necessary. Further details for the maiden MRE can be found in SKY
