The target areas include Nathace and Tundulu hills (Figures 1 & 2, & Table 1) • Gallium mineralisation is open at depth (Figure 4). Though some of the elevated Ga2O3 responses occur within the saprolite clays (TU014: 0-30m; 30m @ 94.63ppm Ga2O3), others occur at depth within fresh rock (TU043: 72-146m; 74m @ 93.26ppm) or TU043: 89-103m; 14m @ 202.79ppm Ga2O3. Deeper gallium potential has not yet been assayed for. • Gallium prices have materially increased in recent years, primarily driven by growing demand in the electronics and semiconductor industries. Raw gallium supply is overwhelmingly dominated by China • Preliminary metallurgical testwork on bulk samples from Tundulu is ongoing, with results due in coming weeks DY6 Metals Ltd (ASX: DY6, “DY6” or “Company”) is pleased to announce that a review of historical drilling at the Tundulu Rare Earth and Phosphate project, Malawi, has uncovered high-grade gallium mineralisation. Significant gallium mineralisation has been identified from surface. Registered Office Level 8, 99 St Georges Terrace Perth WA 6000 P: +61 8 9486 4036 E: info@dy6metals.com dy6metals.com Figure 1. Tundulu Project Location Map and Historical Drill Hole locations over Nathace Hill High Grade Gallium Potential at Tundulu Historical diamond and RC drilling, conducted during 2014 by Mota Engil Minerals & Mining was assayed for gallium. A total of 4901 assays for gallium were completed with 27.7% of the assays containing >40 g/t Ga2O3. Samples from drillholes JMT01 to JMT024 (Figure 2) from previous drilling by Japanese International Cooperation Agency (JICA) in 1980 were not analysed for Gallium. Significant intersections have been calculated from the significant TREO intersections of grade of >5,000ppm over 5 metres in DY6 announcement of 27th May 2024, and the Ga2O3 results in conjunction with the TREO intersections are shown in Appendix 1. dy6metals.com | ASX:DY6 2 Figure 2.

Refer to Appendix 1 for values. Preliminary Metallurgical Testwork As announced 17 October 2024, DY6 has commissioned preliminary metallurgical testwork to be undertaken on a select bulk sample from Tundulu to determine the suitability of the Tundulu deposit to produce a separate rare earth and phosphate concentrate, which is being undertaken by Auralia Metallurgy in Perth. Further testwork is ongoing and will be announced in due course. -ENDS- dy6metals.com | ASX:DY6 5 This announcement has been authorised by the Board of DY6. More information Mr Daniel Smith Mr John Kay Non-Executive Chairman Director & Company Secretary dan.smith@dy6metals.com john.kay@dy6metals.com Competent Persons Statement The Information in this announcement that relates to exploration results, mineral resources or ore reserves is based on information compiled by Mr Allan Younger, who is a Member of the Australasian Institute of Mining and Metallurgy. Mr Younger is a consultant of the Company. Mr Younger has sufficient experience which is relevant to the style of mineralisation and type of deposits under consideration and to the activity that he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the `Australian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves’ (the JORC Code). Mr Younger consents to the inclusion of this information in the form and context in which it appears in this announcement. Mr Younger holds shares in the Company. Mr Younger has not yet visited the site or conducted an in-depth due diligence of the data presented in this announcement. Mr Younger confirms the information in this market announcement is an accurate representation of the available data for the exploration areas mentioned herein, but that further investigation is ongoing. Cautionary Statement Information is this release is considered as historical by nature, and while all care has been taken to review previous reports and available literature, ground testing and confirmation work is yet to be completed by the Company. The historical laboratory analysis was conducted on a range of drill core by reputable laboratories in South Africa. However, there is no guarantee that these results are representative of the Tundulu deposit until further sampling, drilling, assaying and processing test work is conducted by the Company. The Company confirms that it is not aware of any new information or data that materially affects the information included in the announcement. As the historical data was used by the operating company of the time to complete internal resource work and scoping studies, this indicates their confidence in the data quality. As such, DY6 believes the data to be of good quality and reliable. dy6metals.com | ASX:DY6 6 Appendix 1 Table 1: Significant Gallium Intercepts, 40ppm Ga2O3 Cut over 5m, or equivalent to.

767.135 -87 0 120 RC Annexure A: JORC Code, 2012 Edition – Table 1 report Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.) Criteria JORC Code explanation • 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 down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Sampling • Aspects of the determination of techniques 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. Drilling techniques • Drill type (e.g. core, reverse circulation, openhole 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). Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results asses • 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. Commentary • • • • • • • • Reverse Circulation and diamond core drilling samples from 2014 were sent as 1m intervals or were composited to either 2m or 3m intervals based on their radiometric character and HHXRF contents. All procedures were claimed to be industry standard. Drilling was sited on a radial basis around the circular intrusion to best obtain representative samples of geology and mineralisation. No recent drilling is utilised on this program or reported in this announcement. Previous exploration included 2874m of diamond and 6172m of RC drilling. Specifics of hammer type and core diameter is not recorded within available information. Not recorded in historic data. The Company is not able to verify sample recoveries and hence if any bias exists. 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. Subsampling 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. 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. 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. • Qualitative geological logging of core and RC samples was completed in the field. • Specific sampling procedures were not recorded in available information. The core is understood to have been halved and the RC samples riffle split based on personal communications with field staff present. • • • • • Historical analyses are defined only as being ICP; digestion methods are not specified in available data. Additional research is required. Control duplicates, blanks and standards were inserted every 20 samples and comprise 12% of samples analysed. The control samples indicate acceptable levels of accuracy and repeatability. Historical drilling data has been reported in this announcement. • Discuss any adjustment to assay data. 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. • • • Data spacing and distribution • Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. Orientation of data in relation to geological structure • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. Sample security • The measures taken to ensure sample security. Audits or reviews • The results of any audits or reviews of sampling techniques and data. • • • • • • No recent drilling is utilised on this program or reported in this announcement. Historic RC and Diamond collars were DGPS located. The drilling was sited on radial sections to a circular intrusion; at the point of collaring holes are nominally on sections 35m apart and 30m apart on section. This allows coherent correlation of lithological units and mineralisation. Mineralised samples were not composited. Samples were composited over 2m or 3m intervals if their radiometric response and HHXRF contents indicated them to be barren or low-grade material. Not recorded. The historic core is reportedly missing and presumably destroyed. The drilling was sited on radial sections to the circular intrusion, the drilling approaches being perpendicular to the known igneous layering and mineralisation. • Security procedures are unknown but assumed to be in line with industry standard. • No audit of data has been completed to date. Section 2 Reporting of Exploration Results (Criteria listed in the preceding section also apply to this section.) Criteria Mineral tenement and land tenure status JORC Code explanation • Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. Commentary • The Tundulu Exploration Licence, Reference No: EL0731/24 was granted on 27th May 2024 and valid for 3 years with an option to renew. The licence is held under Green Exploration Limited, a wholly-owned subsidiary of DY6 Metals. There are no known impediments to operation in the project area. • • Exploration done by other parties • Acknowledgment and appraisal of exploration by other parties. • • • Geology • Deposit type, geological setting and style of mineralisation. • 9 drillholes, ANG01 to ANG09 (Figure 2) with a meterage of a total meterage of 260m were drilled by M.S. Garson of the Geological Survey Department of the then Nyasaland. These were drilled on behalf of Anglo-American Corporation. Historical exploration is known to have been conducted by JICA (Japanese International Cooperation Agency) from 1988-91. JICA drilled 27 vertical diamond drillholes JMT01 to JMT027 (Figure 2) with a total meterage of 1350m and were drilled to a maximum of 50m. These holes were not analysed for gallium mineralisation. Full details are being researched. The Tundulu licence area was explored for REE and phosphate potential by Mota Engil Minerals & Mining during 2014/15. Most of the known exploration data has been obtained by DY6 however further review and investigation will be required. Small scale phosphate mining also is understood to have been undertaken by Optichem Malawi Ltd in and around 2014. A full literature search continues to be undertaken by DY6 staff to acquire all relevant data. Tundulu is a carbonatite ring complex forming part of the Chilwa Alkaline Province in southern Malawi. The geological structure of the Tundulu Ring Complex comprises of three igneous centres. The first comprises a circular aureole of fenitization about a 2 km diameter plug of syenite. The second carbonatite ring structure centred on Nathace Hill has a diameter of 500600m. Wrench faulting prior to emplacement of the third centre displaced the western half of the Nathace Hill ring structure 250m to the north. The third centre comprises small plugs and thin sheets of metanephelinite and beforsite. • Drill hole Information • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. • Data aggregation methods • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The
