DRILLING UPDATE – TALLEBUNG TIN PROJECT
Additional holes added to the ongoing resource expansion program following broad
visual tin mineralisation* intercepted in new southern-most hole, TBRC078.
Twenty-four (24) holes for a total of approximately 4,500m have been added to the
ongoing 25 holes – 5,000m resource expansion program, with the program aiming to:
Quickly expand on the southern extension to the deposit discovered in
TBRC078, with the aim to include this extension into a future updated MRE,
Further increase this new expansion of the deposit to the south and,
Test northern strike extensions to the Tallebung deposit.
Drillhole TBRC078 represents a 150m step out of the mineralisation along strike to the
south, extending tin mineralisation well beyond the previous southern-most drillhole,
TBRC065**, where results included:
TBRC065:
42m @ 0.20% Tin & 40g/t Silver from 40m, including;
6m @ 0.67% Tin & 68g/t Silver from 67m.
Assay results for the first drillholes are anticipated in the coming weeks.
Additional diamond drilling rig mobilised to bolster the ongoing drilling campaign.
The Board of Sky Metals Limited (‘SKY’ or ‘The Company’) is pleased to provide an update to the ongoing drilling
programme at the Tallebung Tin Project, NSW
TALLEBUNG PROJECT (EL 6699, SKY 100%)
RESOURCE EXTENSION AND INFILL DRILLING PROGRAM
RC resource expansion drilling program has successfully intercepted visual tin mineralisation well beyond the
current extent of the MRE and Exploration Target. The program is aiming to increase the MRE towards the
Exploration Target of 23 – 32 Mt at a grade ranging between 0.14 - 0.17 % tin estimated from the drilling completed
prior to this latest program (SKY:ASX Announcement 23 January 2024). The potential quantity and grade referred
to above as the Exploration Target is conceptual in nature, as there has been insufficient exploration to estimate
a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
*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 June 2024.

SKY CEO Oliver Davies commented: “This is a great start to our resource expansion drilling program and highlights
the significant potential at Tallebung for continuing resource growth. The SKY exploration team have done an
excellent job in targeting additional tin mineralisation in this program, continuing to expand the known tin deposit
footprint beyond of the historic workings and well beyond SKYs current MRE and Exploration Target at Tallebung.
We eagerly await the assay results for this large extension.
“The new additional planned drillholes to follow up this significant result demonstrate how positive this result is
to the ongoing resource expansion at Tallebung. Follow up drilling will mean these new intercepts can quickly be
included in future resource estimates, building the resource towards a ‘critical mass’ for mining studies to be
released.”
SOUTHERN EXTENSION DRILLING
The drilling program started on the southern extent of the Tallebung deposit to target further extensions to the
south. The previous southern-most drillhole, TBRC065, intercepted broad, strong tin mineralisation beyond the
footprint of any historic mining and significantly expanding the potential size of the MRE (SKY:ASX Announcement
24 October 2023), results included:
TBRC065: 42m @ 0.20% Tin & 40g/t Silver from 40m, including;
6m @ 0.67% Tin & 68g/t Silver from 67m, including;
1m @ 2.85% Tin, 0.03% Tungsten & 353g/t Silver from 67m
Hole TBRC078, 150m further along strike to the south from TBRC065, has intersected strong visual tin mineralisation
as cassiterite (tin-oxide) between 64m and 73m (refer Figure 1) and strongly indicates that this program has
successfully achieved the aim of expanding the deposit scale.
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 June 2024.
An additional 10 holes have been added to the current program with the specific intent to infill around this new
discovery. These drillholes are designed to quickly incorporate the new mineralisation intercepted in this drilling
into any new MRE and test for further southern extensions to the deposit.
Drilling is currently continuing towards the eastern area around the historic south lead open pit, adjacent to the
central mining area, where higher-grade intercepts have been recorded in previous drilling (SKY:ASX
Announcement 5 December 2019 & SKY:ASX Announcement 1 November 2021), results included:
TBRC071: 7m @ 0.35% Tin & 25.8g/t Silver from 29m,
17m @ 0.36% Tin & 24.8g/t Silver from 164m, including;
4m @ 1.02% Tin, 86.9g/t Silver, 0.08% Copper & 2.61% Zinc from 174m.
TBRC009: 44m @ 0.21% Tin from 69m, including;
5m @ 1.33% Tin, 0.04% Tungsten & 16.1g/t Silver from 69m.
The successful discovery of tin beyond the extents of the Exploration Target and MRE demonstrates that tin
mineralisation is still open in all directions at Tallebung. Further revealing that the current Exploration Target and
MRE are only limited by the drilling completed to date

Target is outlined in the dashed red line. Highlight intercepts from past drilling are also shown with new holes designed to quickly test around these extensions.

DIAMOND DRILLING PROGRAM
The diamond drilling component has now commenced as of late last week. This program will be using wide
diameter PQ drill core to obtain a large sample for geological and metallurgical studies.
Importantly, the diamond drilling is designed to increase the geological understanding of the deposit to improve
geological models and increase confidence in the expansions of the MRE and Exploration Target. The wide
diameter PQ core is also able to provide material for bulk samples to use in metallurgical testwork, as required.
NORTHERN EXTENSION DRILLING
In addition to the southern expansion drilling, 13 holes are planned to extend the Tallebung MRE to the north.
Quartz veining with visible cassiterite nuggets were discovered in the base of the historic central lead open pit
where alluvial tin resources were extracted in the 1960s - 1970s. These tin-bearing veins have not been previously
tested.
Three rock chip samples were taken of these veins, OD20231020-1 – OD20231020-3, and assay results returned
averaged over 2.10% Tin (SKY:ASX Announcement 23 January 2024). This demonstrates the high-grade nature of
these veins with visible coarse cassiterite, characteristic of the Tallebung Tin Deposit. Drilling is approved to test
under these new extensions to the deposit and incorporate this potential extension into a future updated MRE.
Furthermore, historic workings and drilling results on the northwestern side of the deposit show the potential for
extensions as well and are outside of the already large 23 – 32 Mt Exploration Target estimated above as these
results represent a substantial increase in the tin mineralisation footprint at Tallebung (Figure 1).
NEXT STEPS
This drilling program has been designed to achieve a critical mass MRE and propel the Tallebung project towards
mining studies to show the specifics around the potential for a low-cost tin mining operation at the Tallebung Tin
Project.
The additional 24 holes for approximately ~4,500m of drilling added to the ongoing ~5,000m of RC and diamond
drilling is aimed to continue the work to significantly expand the Tallebung MRE. This expanded program is
estimated to take another 8 weeks with the first assay results of the drilling expected to be received next month.
Following the receipt of the results of this program a new MRE can be estimated, to demonstrate the ongoing
growth of the Tallebung Project.

orientated core allows estimates of the true width and orientation of the mineralisation to be made.
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
No sample bias due to drilling orientation is known. The structural controls on mineralisation is
if material
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
