Announcement PDF ASX: SKY ASX ANNOUNCEMENT 22 April 2024 TALLEBUNG TIN PROJECT RESOURCE EXPANSION DRILLING PROGRAM COMMENCES  Drilling program of approximately 23 RC drillholes and 2-3 diamond drillholes for a total of ~5000m has commenced at Tallebung.  The program will target significant increases to the size and confidence of the current MRE at Tallebung, with the aim to expand the current MRE of 15.6Mt @ 0.15% tin towards the estimated Exploration Target which is only limited by the drilling completed to date*.  SKY continues to consolidate Tallebung as a rare opportunity to establish low-cost tin production, with increasing deposit scale and ideal mineralogy which provides an average of a 5x increase in grade with TOMRA Ore Sorting across the entire deposit, increasing the resource grade of 0.15% tin, to over 0.70% tin*.  The Tallebung tin deposit remains open in all directions and has continued to expand with each drilling program. SKY CEO Oliver Davies commented: “With tin prices rising to the highest levels in almost 2 years, underpinned by growing tin supply uncertainty, this program to increase the MRE at Tallebung represents a vital step towards developing tin resources to meet the growing global demand for tin. Tin demand has remained strong due to its critical role as a solder, holding all electronics together, as well as in solar cell PVs and semiconductors, among many other applications. Supply shortages and uncertainties are pushing the tin price higher as the need for tin is increasing rapidly with global electrification and AI technology. Tallebung’s potential to be a low-cost, Australian tin producer represents an important move to building stable sources of tin to supply the growing demand. This drilling program is key to building a ‘critical mass’ for mining studies and potential future mining at Tallebung.” Figure 1: Tallebung Tin Project – RC drilling rig onsite at the Tallebung Tin Project. * For further details on the MRE for the Tallebung Tin Project please see SKY ASX Announcement 23 January 2024. SKY METALS LIMITED +61 2 6360 1587 2 HAWTHORN PLACE, ORANGE NSW 2800 WWW.SKYMETALS.COM.AU ABN 46 098 952 035 The Board of Sky Metals Limited (‘SKY’ or ‘The Company’) is pleased to advise of the commencement of RC drilling at the Tallebung Tin Project, NSW with a diamond drilling component to begin in the following weeks. TALLEBUNG PROJECT (EL 6699, SKY 100%) RESOURCE EXTENSION AND INFILL DRILLING PROGRAM The drilling program aims to increase the MRE towards the estimated Exploration Target of approximately 23 – 32 Mt at a grade ranging between 0.14 - 0.17 % tin defined from the drilling completed to date and remains open in all directions (SKY ASX Announcement 23 January 2024). This program will also aim to increase the confidence in the resources at Tallebung and convert further resources into indicated resources. Increasing the confidence in the Exploration Target and MRE is the only remaining step before SKY can release mining studies for Tallebung. This drilling program will be designed to propel the Tallebung project towards announcing mining studies to show the specifics around the potential low-cost tin mining operation at the Tallebung Tin Project. Figure 2: Tallebung Tin Project – Plan showing existing drillhole collars and the planned drillholes in red. An outline also shows the extent of the current estimated area for the Exploration Target. Strong intercepts are highlighted to the east and south which will be further drilled in this latest drilling program to expand the MRE in these higher-grade areas of the Tallebung deposit. 2 The program will target the southern and central areas of the historic Tallebung Tin Mining Field where the majority of the historic hardrock workings are located (Figure 1). This program will focus on converting a further portion of the Exploration Target into a ‘critical mass’ MRE of inferred and indicated resources. Drilling will focus on the eastern area, adjacent to the central mining area, where higher-grade intercepts have been recorded in previous drilling, including: 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 program will also target further extensions to the south, where TBRC065 intercepted exception broad, strong tin mineralisation beyond the footprint of any historic mining and significantly expanding the potential size of the MRE, 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 The diamond drilling program is scheduled to begin in a couple of weeks. The diamond drillholes will be drilled with wide diameter PQ drill core. 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, as required. This program of ~5,000m of RC and diamond drilling at Tallebung is estimated to take approximately 6 weeks with the first assay results of the drilling expected to be received in the next 1-2 months. 3 This report has been approved for release by the Board of Directors.
