SKY Managing Director & CEO Oliver Davies commented: “These latest results continue to show the strength of the Tallebung system, with multiple broad, shallow, high‑grade tin‑tungsten‑silver intercepts returned from within the central resource area. Importantly, this drilling has successfully targeted shallow, high-grade zones for early mine life production, where we see the opportunity to access higher‑grade shallow material in the early years of operations. SKY is building a highly robust dataset that will support the upcoming Mineral Resource update and PFS. The consistency and continuity of these high‑grade zones further builds confidence in Tallebung as a scalable, near‑term development opportunity, with strong potential to optimise early project economics.” 2 Figure 1: Plan showing the location of new drilling results. Drill-hole collars, previously reported highlight drill intercepts and the limits of the existing Tallebung MRE are shown over surface geology. Sky Metals Limited (ASX: SKY) (“Sky Metals” or the “Company”) is pleased to report further strong results from recently completed in-fill drilling at its 100%‑owned Tallebung Tin-Tungsten-Silver Project in central New South Wales, as momentum continues to build ahead of a pivotal Mineral Resource update this quarter. TALLEBUNG PROJECT (EL 6699, SKY 100%) SHALLOW HIGH‑GRADE ZONES SUPPORT EARLY MINE DEVELOPMENT POTENTIAL Recent drilling has returned broad, shallow, high‑grade tin‑tungsten‑silver intersections within the central portion of the Tallebung deposit. These results have been returned from areas that are expected to form a key component of the early mine life production profile at Tallebung. 3 The intercepts define continuous, near‑surface mineralisation with strong grades and widths, reinforcing the suitability of Tallebung for open‑pit mining and supporting an optimised mine schedule that prioritises higher- margin material in the initial years of operations to support rapid capital payback. Importantly, these results are located within the core resource area, where drill density has now increased significantly, enhancing both geological confidence and continuity of mineralisation. Figure 2: Plan showing the location of the new drilling results in the central in-fill drilling pattern. Drill-hole collars, previously reported highlight drill intercepts with highlight new drill-hole intercepts are shown over surface geology. STRONG DRILLING RESULTS REINFORCE RESOURCE QUALITY The latest results demonstrate consistent high‑grade mineralisation across multiple zones, including: • Thick intervals of >1% tin from shallow depths, including TBRC395 (23m @ 1.14% Sn from 19m); • High‑grade sub‑intervals exceeding 2-9% tin, supporting strong grade continuity; and • Associated tungsten and silver credits, significantly enhancing overall project economics. 4 These results continue to confirm the presence of robust, laterally continuous mineralised zones, supporting both resource growth and potential optimisation of early mine scheduling. Figure 3: Cross‑section showing new drilling results from TBRC377 alongside previously reported drill‑hole intercepts. The surface positions of historical workings are also displayed, with the mineralisation hosted in stacked vein packages that extend to surface. UPDATED MRE AND PFS ON TRACK The Company confirms that these results will be incorporated into an updated Mineral Resource Estimate (MRE) and Pre-Feasibility Study (PFS), both on track for release in the current quarter. The updated MRE will incorporate the expanded drilling database now comprising more than 500 holes, representing a substantial increase in data compared to the current resource. This expanded dataset is expected to deliver improved resource confidence and support detailed mine planning as part of the PFS. FURTHER RESULTS AND ONGOING MOMENTUM A significant number of additional assays from both in-fill and extensional drilling remain pending and are expected to be released in the coming weeks. These results are expected to further strengthen the resource base and support ongoing growth of the deposit. Sky Metals remains focused on systematically advancing Tallebung through exploration, resource definition and development studies, positioning the project as a near‑term tin, tungsten and silver production opportunity. 5 This announcement is authorised for release by the Board of Sky Metals Limited.

Mr. Oliver Davies is an employee and director of Sky Metals Ltd and has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.’ Mr. Davies consents to the inclusion in this report of the matters based on his information in the form and context in which it appears. About the Tallebung Tin Project (100% SKY) Tallebung stands as an open-pit, technology enabled, near-term tin development project. 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 tin-oxide (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. 6 Previously Reported Information The information in this report that references previously reported exploration results is extracted from the Company’s ASX market announcements released on the date noted in the body of the text where that reference appears.

TABLE 1 Section 1 Sampling Techniques and Data – TALLEBUNG PROJECT (Criteria in this section apply to all succeeding sections) Criteria Explanation Commentary Sampling techniques • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. 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. All samples were submitted to ALS Orange for preparation and assaying. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Assay standards or blanks are inserted at least every 50 samples. All sample lab received weights show consistency with recovery and interval length. • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual Commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. Each sample was dried, crushed and pulverised as per standard industry practice. 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 mineralisation has not been logged, 4m Composites have been made by using a spear to Combine equal amounts of samples from each 1m calico. The primary metal of interest, tin (Sn) and also tungsten (W) were determined by lithium borate fusion XRF (method ALS – ME-MS85) – considered appropriate for these elements. Multielement assaying was completed for 48 elements by 0.25g four-acid digest with ICPMS determination (method ALS – ME- MS61) or for infill holes, assay of Ag, As, Cu, Pb, Zn with ICP determination (method ALS – ME-ICP61) Pulps were also pulverised to ensure the sample is homogenised. Multielement assaying was completed for 48 elements by 0.25g four-acid digest with ICPMS determination (method ME-ICP61). Sn & W were analysed at ALS via ME-MS85 by lithium meta-borate fusion and ICP-MS. Overlimit samples are analysed via ME-XRF30 fusion. 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, face- sampling bit or other type, whether core is oriented and if so, by what method, etc) Reverse circulation (RC) drilling using 110mm rods, 144mm face sampling hammer. Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • 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 RC drilling - high capacity RC rig was used to enable dry samples collected. Drill cyclone is cleaned between rod changes and after each hole to minimise cross-hole contamination. Sample weights are recorded for each sample. Recoveries were generally excellent and consistent, however, if samples were wet the recoveries were less consistent. 15 Criteria Explanation Commentary 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. Logging • 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. Both qualitative and quantitative data is collected. All rock chips were digitally photographed. 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. 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. Sample sizes are industry standard and considered appropriate. No field duplicates are taken for the rock chip samples. The sample was crushed and pulverised to 90% passing 75 microns. This was considered to appropriately homogenise the sample. The available data suggests that sampling procedures provide sufficiently representative subsamples for the current interpretation. 16 Criteria Explanation Commentary Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established Standard assay procedures performed by a reputable assay lab, (ALS), were undertaken. Forty-eight elements Ag, As, Cu, Fe, Pb, S, Zn are digested by four-acid digest then analysed by ICPMS (method ME- MS61) or for infill holes, assay of Ag, As, Cu, Pb, Zn with ICP determination (method ALS – ME-ICP61) Sn and W assays were generated by lithium borate fusion XRF (method ME-MS85) – considered appropriate for these elements. No geophysical tools were used in the determination of assay results. Certified reference material or blanks were inserted at least every 50 samples. Standards are purchased from Certified Reference Material manufacture Companies: Standards were purchased in foil lined packets of between 60g and 100g. Different reference materials were used to cover high grade, medium grade, low grade, and trace ranges of elements, with a primary focus on Sn, Ag and W. Verification of sampling and assaying • The verification of significant intersections by either independent or alternative Company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data Drill data is Compiled and collated and reviewed by senior staff. External consultants do not routinely verify exploration data until resource estimation procedures are deemed necessary. The intersection calculations were viewed by >1 geological personnel. Twinned holes have been used by past explorers to v
