TALLEBUNG TIN PROJECT, NSW – DRILLING UPDATE
FURTHER HIGHER-GRADE TIN INTERCEPTS IN SOUTHERN
EXTENSION DRILLING PROGRAM
Shallow, higher-grade tin intersections returned from southern extension drilling, with
highlights including:
TBRC105:
7m @ 0.58% tin from 62m, including:
2m @ 1.82% tin from 62m.
TBRC110:
6m @ 0.59% tin & 28.8g/t silver from 50m, including:
3m @ 1.02% tin & 22.3g/t silver from 53m, within:
27m @ 0.24% tin & 16.9g/t silver from 47m.
Results show strong continuity of mineralisation surrounding the high-grade extension
discovered in the recent 150m step-out hole to the south, which returned:
TBRC078:
11m @ 1.02% tin, 77.9g/t silver & 0.13% tungsten from 64m
The continuity shown in these latest results demonstrates a coherent higher-grade
zone of shallow tin mineralisation extending well beyond the boundaries of the current
Mineral Resource Estimate (MRE)1 at the Tallebung Project.
These areas of shallow, higher-grade tin mineralisation being discovered and
expanded in recent drilling will be a key focus for potential future early mining at
Tallebung to facilitate rapid payback of Capex.
Assays have now been received for 10 holes of the 13-hole RC program, with results
for the remaining three holes anticipated over the coming weeks.
SKY CEO Oliver Davies commented: “These latest higher-grade intercepts from Tallebung are highly encouraging,
a tin grade of 0.58% is equivalent to around 2% copper, with the tin price maintaining strong levels of ~3.5x the
copper price on the LME and before beneficiation via TOMRA ore sorting. The growing continuity of the shallow,
higher-grade tin mineralisation discovered at Tallebung is expected to strongly enhance the project economics,
with this mineralisation ideally suited to be exploited in the early phase of a future mining operation to generate
early cash flow and enable rapid payback of project Capex.
“The strong tin price, combined with the growing continuity of shallow higher-grade tin mineralisation in recent
drilling and our extraordinary success with recent ore sorting testwork all highlight the excellent progress and
unique opportunity developing at SKY’s Tallebung Tin Project.”

The Board of Sky Metals Limited (‘SKY’ or ‘The Company’) is pleased to report initial assay results from the southern
extension Reverse Circulation (RC) drilling program as well as final diamond drilling results from the Tallebung Tin
Project, NSW.
TALLEBUNG PROJECT (EL 6699, SKY 100%)
RC DRILLING PROGRAM
A program of 13 Reverse Circulation (RC) drill-holes (TBRC103-TBRC115, Figure 1) has successfully confirmed the
continuity of recently discovered high-grade tin mineralisation, well beyond the southern margin of the current
MRE. The program was completed to expand this southern extension where the southernmost drillhole, TBRC078,
intercepted high-grade tin mineralisation including:
TBRC078:
11m @ 1.02% Sn, 77.9g/t Ag & 0.13% W from 64m
Holes TBRC103-110 were drilled to infill these results and continue to expand the deposit to the south. Best results
were from holes TBRC105 and TBRC110 which were drilled approximately 50m along strike to the southeast and
down dip from TBRC078, respectively. Highlights from these drillholes include:
TBRC103:
14m @ 0.22% Sn & 27.1g/t Ag from 59m; including:
1m @ 1.74% Sn & 296g/t Ag from 60m.
TBRC104:
6m @ 0.21% Sn, 0.03% W & 5.39g/t Ag from 59m; including:
1m @ 1.74% Sn & 296g/t Ag from 60m.
TBRC105:
7m @ 0.58% Sn from 62m, including:
2m @ 1.82% Sn from 62m.
TBRC106:
3m @ 0.18% Sn & 8.81g/t Ag from 15m.
TBRC108:
23m @ 0.21% Sn. 0.07% W & 10.2g/t Ag from 82m; including:
1m @ 0.96% Sn, 1.09% W & 92.3g/t Ag from 82m; and
1m @ 1.17% Sn from 90m.
TBRC109:
2m @ 0.44% Sn, 190.5/t Ag, 0.07% W & 0.05% Cu from 68m.
TBRC110:
6m @ 0.59% Sn & 28.8g/t Ag from 50m, including:
3m @ 1.02% Sn & 22.3g/t Ag from 53m, within:
27m @ 0.24% Sn & 16.9g/t Ag from 47m.
Future work will focus on building the Company’s geological understanding of this newly discovered area and
continuing to expand this zone of tin mineralisation delineated beyond the southern margin of the current MRE.
DIAMOND DRILLING PROGRAM
A program of five diamond drill-holes (TBD009-TBD013, Figure 1) was completed to in-fill the current Tallebung
MRE of 15.6Mt @ 0.15% Sn for 23.3kt of contained Sn (SKY ASX Announcement 23 January 2024). Assay results for
the first four holes (TBD009-TBD012) were reported in SKY ASX Announcement 28 August 2024.
Assays have now been received for the final hole in this program, TBD013, successfully confirming further tin
mineralisation well outside of the current MRE and effectively doubling the width of the known mineralisation
footprint on the northern margin of the Tallebung deposit (Figure 1, Table 2). Results include:
TBD013:
9.4m @ 0.21% Sn & 0.04% W from 9.5m, including:
0.5m @ 1.72% Sn, 0.28% W & 9.55g/t Ag from 9.5m.

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%

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

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

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.
Audits or reviews
The results of any audits or reviews of sampling techniques and data
The Company has external consultants to verify exploration data for the resource estimation process.

Acknowledgment and appraisal of exploration by other parties
The Tallebung Project area was subject to a modern, large-scale alluvial/colluvial mining by the Tullebong
Tin Syndicate in the period 1963-1972. The Tullebong Syndicate Completed a program of 24 short
diamond holes in 1968-69 designed to test the lode mineralisation at Tallebung.
Pruessag Completed a large-scale assessment of the alluvial tin deposits in 1984-85, including RC drilling,
identifying the potential for a large, low grade alluvial deep lead.
In recent exploration, YTC Resources (now Aurelia Metals Ltd) Completed trenching, diamond drilling,
aircore drilling of tailings, and resistivity geophysics (EH4) at the Tallebung tin field. YTC recognised the
