Tallebung is uniquely placed to provide secure tin supply, to feed irreplaceable and rapidly expanding tin demand, essential in semi-conductors, 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 tinoxide (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.

Results include: TBRC118: 6m @ 1.01% tin from 52m, including: 2m @ 2.54% tin from 54m. TBRC116: 13m @ 0.33% tin from 70m, including: 5m @ 0.74% tin from 76m. TBRC117: 2m @ 1.10% tin from 69m. • These holes have widened the newly discovered zone of high-grade tin intersected last year to the south of the current MRE: TBRC078: 11m at 1.02% Sn from 54m • Importantly, Tallebung ore sorting variability studies completed last year1 showed the potential to achieve a significant and consistent upgrade of high-grade tin mineralisation: TBD006 (25-35m): – 1.15% tin upgraded 4.6x to 5.31% tin with 99% recovery of tin. • A stream of results will continue over the coming months as the current drilling program targets further shallow extensions and in-fills the existing Tallebung MRE. • In light of the success of the ongoing drilling, the current RC program has been more than doubled in size with the addition of ~80 RC holes to continue to build on these excellent results. Over 100 holes have now been permitted ready for drilling. • In parallel, SKY is advancing the bulk sample metallurgical program to optimise the process flowsheet and produce marketable tin concentrates to aid in off-take marketing. SKY Managing Director & CEO Oliver Davies commented: “We have made a cracking start to the RC program, with shallow, high-grade tin returned in each of the first three holes. The initial drilling has expanded the high-grade zone immediately south of the MRE, adding substantial momentum to our current exploration program. The tin price is maintaining levels of 3-3.5x the copper price at current LME spot prices and demonstrates the very high value nature of these intercepts., reinforcing the strategic importance of the shallow extensions we are finding to the south and east of the current deposit. This is an exciting time for our shareholders as we begin to uncover the true potential of this extensive tin field.” Watch a video summary of this announcement & engage with SKY here 1 For further details on the ore sorting variability testwork 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 Sky Metals Ltd (ASX: SKY) (‘SKY’ or the ‘Company’) is pleased to report initial 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 Assay results have been received for the first three (3) holes (TBRC116-118) of the large ongoing Reverse Circulation (RC) drilling program with high-grade tin intersected in the first three holes completed. All three holes were located in the newly discovered high-grade zone to the south of the current MRE (see Figure 1). Figure 1: Plan showing the location of the drill-holes in the latest program as well as the new extensional drillholes added to the program with existing highlight drill intercepts. The boundary of the existing Tallebung MRE is also shown over the surface geology map. The first three (3) RC holes (TBRC116-118) were designed to expand the newly discovered high-grade southern extension to the Tallebung deposit (figure 1). The results have confirmed significant extensions to this strategically important high-grade zone, with results including: 2 TBRC118: 6m @ 1.01% Sn from 52m, including: 2m @ 2.54% Sn from 54m. TBRC116: 14m @ 0.31% Sn from 70m, including: 6m @ 0.62% Sn from 70m. TBRC117: 2m @ 1.10% Sn from 69m. Drilling has continued to target extensions to the southern area of the existing MRE, aiming to expand Resources and increase Resource confidence with shallow RC holes. 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. Drilling next proceeded to the eastern margin of the deposit to explore for further extensions of shallow, highergrade mineralisation that can be incorporated into the early stages of the mine plan to bolster the Company’s goal of achieving a faster payback of project CAPEX. The program continues to make excellent progress, with a total of 42 holes completed to date. Given the exciting results already being generated, approvals have now been submitted to further substantially expand the drilling program with an additional approximately 80 holes planned, 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 the historic workings, suggesting that the best parts of the deposit may yet to be found. A steady stream of results are expected over the next few months as the drilling programs advance. The Company will continue to provide regular updates as assay results are received. This announcement is authorised for release by the Board of Sky Metals Limited.

Drilling techniques • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, facesampling bit or other type, whether core is oriented and if so, by what method, etc) Drill sample recovery • • • Method of recording and assessing core and chip sample recoveries and results assessed. RC drilling - high capacity RC rig was used to enable dry samples collected. Drill cyclone is cleaned Measures taken to maximise sample recovery and ensure representative nature of the samples. between rod changes and after each hole to minimise cross-hole contamination. 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. 6 Criteria Logging • • • Explanation Commentary Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography 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. Sub-sampling techniques and sample preparation • • • • • • If core, whether cut or sawn and whether quarter, half or all core taken If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry For all sample types, the nature, quality and appropriateness of the sample preparation technique Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples 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.
