Mineral Resource Estimate and Scoping Study iv These encouraging results build on the recently completed Mineral Resource Estimate (MRE) update and Stage 1 Scoping Study (Study), which delivered a substantial increase in resources and robust economics. Scoping Study Using Base Case $4,250/oz Gold Price is approximately v: (pre-tax) NPV at 8% A$290.4 million IRR 112% Free cash flow A$314.1M Total Gold Production 172,600oz Au Mine Life of Stage 1 Study 5.5 Years All-in-sustaining cost A$1,726/oz The Study only evaluated 209.5koz located in the Kylo and Strauss deposits, part of the Mt Carrington area. A potential Stage 2 Study will assess the total 650koz Au and 24.3Moz Ag defined in the recently updated 2025 MRE vi, which was not evaluated in the Study. This MRE contained and open pit MRE of 0.65Moz Au, 24.3Moz Ag, 147kt Zn, 33kt Pb, 20kt Cu forvi: o 0.8Moz AuEq (from gold-rich deposits) plus 35Moz AgEq (from silver-rich deposits). 1 See Section ‘Appendix 3’ page 10 for MRE details, Au/AgEq calculations; 2 See Section ‘Endnotes’ page 20 for references Page 1 of 20 | ABN 43 650 398 897 3/202 Russell Street Bathurst, 2795 www.legacyminerals.com.au ASX: LGM Page 2 of 20 Legacy Minerals Holdings Limited (ASX: LGM, Legacy Minerals or the Company) is pleased to report assay results from new sampling of historic diamond drill core at its Drake Project (EL6273, EL9616, EL9727, and ALA75) in NSW, Australia. Management comment – Legacy Minerals CEO & Managing Director Christopher Byrne said: “The Drake Project continues to impress with these latest results, highlighting the clear untested potential for resource growth and discovery across the Project. These diamond drill holes were completed historically to assess the geotechnical characteristics of the open pit walls in preparation for a definitive prefeasibility study. As such, they were not targeting mineralisation and were not sent for assay despite large zones of visible sulphides. Results from drillhole GT005 of 95m at 0.9g/t Au and 0.35% Zn from 2m including 10m at 6.0g/t Au from 69m and drillhole GT001 of 18m at 1.4g/t Au and 3.8% Pb+Zn from 0m highlight the scale and demonstrate the strong potential to expand the resource which is open in all directions, in particular at depth where minimal drilling has occurred. These results build on previous high-grade drilling including 12.82m at 48g/t Au and 2,589g/t Ag from 16m and 118m at 1.71g/t Au and 1.12% Zn from 2m; demonstrating the scale and potential of the system which was confirmed in the recently announced Mineral Resource Estimate and the Stage One Scoping Study at Drake (April 2025). This Study showed the potential to deliver significant value for shareholders as a low-margin asset with an "all-in sustaining cost" ("AISC") of A$1,709/oz at an assumed base case gold price of A$4,250/oz. This base case has a significant upside, with 24.3Moz of silver and 450koz of gold remaining outside the Stage 1 Scoping Study. Impressively, the pre-tax NPV increases to A$404 million and the IRR to 151% at a gold price of A$5,000/oz. The airborne mobile-magnetotelluric geophysical survey is also now complete at Drake. The results will provide the first systematic look at the broader region in 30 years, and we’re excited by the potential insights it will deliver near the current Mineral Resource and regionally.” New Diamond Drilling Assay Results In 2021 Thomson Resources drilled seven diamond drill holes as part of work for a proposed DFS on the Mt Carrington Gold First Project which was part of the earn-in obligations under the Earn-in and Joint Venture Agreement with White Rock Minerals Ltd vii. Samples of the core from each hole were to be sent for geotechnical compression and shear tests to assist with open-pit stability studies, but these tests were not completed. Of the seven drill holes completed in 2021, six could be recovered at the Drake core yard and their quality could be verified. 6F The drilling was done within the Strauss and Kylo deposits as well as testing adjacent areas. Three of the short diamond holes were drilled on the margins of the optimised Kylo open pit (GT001-3), two were drilled on the margin of the Strauss open pit (GT004-5) and two were drilled at Kylo West (GT0067). A number of intervals were unable to be located including 28-75m of GT001. 36-40m of GT002, entire drill hole GT003, 65-95m of GT004, 0-30m and 45-70m of GT006, and 0-13m of GT007. The Company is working towards locating and validating these missing sample intervals, which present the potential to extend the known mineralisation further. These historical drill holes have confirmed that mineralisation extends beyond the current pit shells that were optimised for gold-silver resources as part of the recently completed Stage 1 Scoping Study.

Strauss cross-section highlighting recently returned assays from GT004 and GT005. Future work program The Company is awaiting the results of the completed Airborne Mobile MT survey and will incorporate this data into the Project database. This will aid the geological understanding of the Project and potentially to deliver a new generation of greenfield and brownfield drill targets. Final results are expected within the next few weeks. Airborne Mobile MT has been successfully used by companies, including K92 Mining Inc., to define targets in a gold-copper epithermal setting similar to Drake and supported K92’s Kainantu growth from 0.88Moz AuEq in 2015 to 18Moz AuEq in 2024iii. The exploration approach has three clear strategic goals: 1. Resource extension assessment: Test the brownfield targets at depth and along strike of highgrade gold, silver, and copper zones that target substantial Resource growth. 2. Discovery drilling - drilling to explore new greenfield epithermal-porphyry discoveries within the Drake Caldera. 3. Increase resource confidence by confirming historical drill results within existing Inferred Resources. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 5 of 20 Figure 5. Drake Project showing deposits and major Prospects. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 6 of 20 Geological Overview The Drake Project sits within the highly prospective New England Fold Belt (NEFB), one of a number of epithermal gold, silver and base metal districts that formed along the east coast of Australia during the Permian age as back arc extensional volcanic basins. A number of major mines and deposits occur within the NEFB, including the Hillgrove Mine (1.0Moz Au, 93kt Sb viii), Cracow gold mine (2.5Moz Au @ 4.97g/t) ix, Mt Carlton gold mine (1.2Moz Au, 12Moz Ag) x, Mt Rawdon gold mine (2.5Moz Au xi), and Mt Morgan (8Moz Au xii). 1F7F 2F8F 3F9F 4F10F 5F1F The Lunatic Field lies along a north-south zone about midway between the Demon Fault and the western margin of the Clarence Moreton Basin and may be structurally related to either of these features. The Lunatic Field comprises a western belt of antimony and eastern belt of gold deposits with mineralised veins hosted by Emu Creek Formation sediments and at Ottos lode (Pretty Gully) by Jenny Lind Granite. The Drake epithermal deposits are hosted by the Drake Volcanics, a NW-trending 60km x 10km Permian bimodal volcano-sedimentary sequence within the Wandsworth Volcanic Group near the north-eastern margins of the Southern New England Fold Belt. The Drake Volcanic sequence and associated intrusions are host and interpreted source to the volcanogenic epithermal Au-Ag-Cu-Pb-Zn mineralisation developed at Mt Carrington. The majority of the Drake Volcanics and associated mineralisation are centred within a large-scale circular caldera with a low magnetic signature which is 20km diameter. Previous exploration is limited to regional geophysics and surface geochemical sampling including stream sediment sampling, rock chip sampling, soil sampling and drill testing. The Project is centred on a poorly understood but regionally important, low-sulphidation, epithermal, gold, silver, zinc and copper mineralised system. The Porgera Goldfield provides a good analogy to Drake in that gold-silver associated with galenasphalerite forms marginal to felsic-intermediate domes. Many recent discoveries feature settings where veins occur only in competent host rocks, which have fractured well but are obscured by overlying incompetent host rocks (El Penon, Chile; Palmarejo, Mexico; Hishikari, Japan). About the Drake Project The Drake Project contains three granted exploration licenses covering 390km2 and an Assessment Lease Application (ALA75) covering 0.46km2 over the Mt Carrington Area. An assessment lease authority exists as a ‘bridge’ between exploration and mining, where progression to mining status is reasonably foreseeable. The Project encompasses substantial infrastructure on the granted exploration licenses, including a tailings dam, grid easements, a 750ML water source, a site office, accommodation, a core shed, and core processing facilities. This Study covers resources and infrastructure contained across ALA75 and Exploration License EL6273. The Drake Project has combined resources of 34Mt containing 0.8Moz of contained AuEq metal and 35Moz of contained AgEq metal. Gold and silver are the dominant contained metals in the Resource (653koz Au, 24.3Moz Ag), with significant zinc content (147kt Zn) and lesser amounts of copper (20kt Cu) and lead (33kt Pb). The Drake Project’s total resource consists of three components: the Red Rock Mine (8.6mt at 0.84g/t AuEq), the White Rock Group (6.2mt at 92g/t AgEq), the Mt Carrington gold rich resource (14.5mt at 1.2g/t AuEq) and Mt Carrington silver rich resource (5.1mt at 106g/t AgEq)iv. The 2025 Scoping Studyiv evaluated the potential development of 209.5koz at the Mt Carrington Group. The Scoping Study demonstrated the potential for the Project to produce ~31,400oz of gold per annum for a total of ~172,600 ounces of gold, at an "all-in sustaining cost" ("AISC") of ~A$1,726/oz over an initial five-and-a-half-year production period generate strong free cashflows averaging ~A$52.8 million pre-tax per annum during its first five years of operation, an IRR of 112% and a robust NPV of ~A$290.4 million.

Refer to the following sections of this release and Appendix B, ‘JORC Table 1’, for further details on the Mineral Resource Estimate. Please refer to the compliance statements for details on parameters used to calculate metal equivalents. Metal Equivalent Calculations For Red Rock and Mt Carrington, AuEq is calculated using the formula: AuEq = Au + 0.00986xAg + 1.237237xCu + 0.3493xZn + 0.2784xPb. Recoveries applied are 83.1% (Au), 68.6% (Ag), 85% (Cu), 80% (Zn) and 85% (Pb). For White Rock, AgEq is calculated using the formula: AgEq = Ag + 84.0712xAu + 93.2167xCu + 36.0156xZn + 27.0117xPb. Recoveries applied are 72% (Au), $71.7% (Ag), 66% (Cu), 85% (Zn) and 85% (Pb). Mt Carrington Silver Deposit Ag + 82.4186xAu + 63.0108xCu + 27.0046xZn + 21.5193xPb, Recoveries applied are 83.1% (Au), 68.6% (Ag), 85% (Cu), 80% (Zn) and 85% (Pb). Formulas calculated using silver price of A$43/oz, gold price of A$3,600/oz, copper price of A$14,000/t, zinc price of A$4,200/t and lead price of A$3,150/t. In the opinion of the Company, all elements included in the metal equivalent calculation have a reasonable potential to be sold and recovered based on current market conditions and metallurgical test work up to 2017. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 12 of 20 Appendix 4 – JORC Code, 2021 Edition Table 1 Section 1 Sampling Techniques and Data 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. Commentary The diamond drill core sampled and assayed is from a historical geotechnical drilling program completed by Thomson Resources in 2021. The core has been securely stored since the completion of the drilling. The core was sampled by Legacy Minerals representatives. Core size was HQ3 core (diameter: 63.5mm) to end of hole (EOH) for all drill holes. Thomson Resources used a reputable drilling contractor, BG Drilling, with a suitable rig. Diamond drill core provides a high-quality sample that is logged for lithological, structural, geotechnical, and other attributes. Subsampling of the core was carried out as per industry best practice. Single shot downhole surveys were taken every 15 m, utilising a Reflex-EZ. Surveys were listed on drill plods and then passed onto geologists to record in the database. Recording in the database was not completed at the time and as such it has not been possible to locate the survey files at this time. The drill hole collar locations were initially set out with a handheld GPS and were later picked up with a Trimble DGPS. Sampling Techniques Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. The drill core was orientated using core orientation tool by the drilling contractor with Thomson staff supervision. These orientations are extended onto the remainder of the core and meter marks for logging. The visible structural features (veins, bedding, foliation, faults) are measured against the core orientation marks. Drill core was cut in half along the axis line, and assayed at a certified assay laboratory, ALS Laboratories, Brisbane. Sampling was done at a 1m nominal interval, unless historical sampling was done in the metre. A certified sample standard was inserted a minimum of 1:20 samples. 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 1m 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. The drill core was cut by TMZ related staff and sampling intervals verified by LGM personnel. Samples were transported to ALS Laboratory in Brisbane for assaying. Samples are crushed to 6mm and then pulverized to 85% passing 75 microns. A 50g split of the sample was fired assayed for gold. The lower detection limit for gold is 0.002 ppm, which is believed to be an appropriate detection level. All other elements including copper and base metals (total 48 element suite) are analysed using a 4-acid acid digest and an ICP finish (ALS code: ME-MS61 + Au-AA21). Assay standards, blanks and duplicates were analysed as part of the standard laboratory analytical procedures. Company standards were introduced into the sampling at a ratio minimum of 1 standard for every 20 samples and laboratory duplicates every 30 samples. Sample length: Core was SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 13 of 20 sampled in 1m sample interval lengths except for where historical Geotech sampling removed core. Pulps are retained by LGM for any follow-up analysis. Drilling techniques Drill sample recovery 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). Diamond drilling using industry standard techniques. HQ3 core (diameter: 63.5mm) to end of hole (EOH). Method of recording and assessing core and chip sample recoveries and results assessed. Core recoveries were recorded during drilling and reconciled during the core processing and geological logging. Measures taken to maximise sample recovery and ensure representative nature of the samples. Core was measured and marked after each drill run using wooden blocks calibrating depth. 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. No sample recovery issues have been identified that would impact on potential sample bias in the competent fresh rocks that host the mineralised intervals. During the Geotechnical drill program, geological information collected included: • Lithology • Weathering • Alteration • Mineralisation • Structure + structural orientation 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. Geological logging was undertaken prior to geotechnical logging. Geotechnical logging included: • Weathering • Alteration • Field Estimated Strength Logging • Core recovery • RQD • Fracture Count • Joint sets/thickness/shape/roughness/alteration and infill Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Geological logging recorded lithology, weathering, Alteration, mineralisation, structures and other noticeable features. This is generally qualitative. Geotechnical logging was based on intervals defined by common geological characteristics or geotechnical features such as jointing/alteration, to a maximum length of three metres. All core trays were photographed The total length and percentage of the relevant intersections logged. All drill holes were geologically and geotechnically logged in full by Thomson Resources SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 14 of 20 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. Sub‐sampling techniques and sample preparation Not applicable For all sample types, the nature, quality and appropriateness of the sample preparation technique. Drill core was cut in half along the length and the total half core submitted as the sample. This procedure meets industry standards where approximately 50% of the total sample taken from the diamond core is submitted. All mineralised intervals and surrounding wall rock were submitted for assay. Sample weights are recorded by the lab. Samples were delivered by Legacy Minerals personnel to ALS Minerals Laboratory, Brisbane NSW. Sample preparation will comprise of an industry standard of drying, jaw crushing and pulverising to -75 microns (85% passing) (ALS cod
