ASX Announcement 30 October 2026 ASX: LGM ASX: LGM SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB Page 2 of 16 Management Comment Legacy Minerals CEO and Managing Director, Christopher Byrne, said: “The September Quarter has been an important period for Legacy Minerals, with the delivery of an updated Mineral Resource Estimate for our flagship Mt Carrington Project providing the opportunity to evaluate a larger-scale Project with enhanced economies of scale. The updated Resource totals 1.6 million ounces of contained gold-equivalent metal, with Resource tonnes increased by 39%, silver ounces by 44%, and Indicated Resources up by 69% to 19.3Mt. On the back of the update, Legacy Minerals is now well underway with completing an a larger Scoping Study for Mt Carrington to investigate the merits of increasing plant throughput beyond the original one million tonnes per annum envisaged in the May 2026 Study. We see strong potential to significantly enhance the outcomes of the existing Scoping Study, with the outcomes of the larger study expected to be announced in the December 2026 Quarter. On the exploration front, we completed our initial drilling campaign at the Emu prospect at Mt Carrington, which provided our first modern drill test of two high-priority regional targets, as well as commencing Phase 2 drilling at Mascotte. Assays from both programs were awaited at Quarter-end. Elsewhere, we have engaged WSP Australia to complete an updated Mineral Resource Estimate for our NiCo Young Project in central NSW that will seek to include scandium alongside nickel and cobalt within the Resource, as well as identifying three untested copper-gold targets at our Rockley Project. All of these work programs position Legacy for a very active end to 2026, with plenty of news flow ahead for shareholders.” Mt Carrington Project The Mt Carrington Project sits within the highly prospective New England Fold Belt (NEFB). It is one of several epithermal gold, silver and base metal districts that formed along the Australian east coast during the Permian age as back-arc extensional volcanic basins. Several significant mines and deposits occur within the NEFB, including the Cracow gold mine, Mt Carlton gold mine, Mt Rawdon gold mine and the Mt Carrington Mine. Mineral Resource Update During the Quarter, Legacy announced a significant upgrade to the Mineral Resource Estimate (MRE) for the Mt Carrington Projectxiv , with the updated MRE comprising 47.9 million tonnes grading 1.0g/t AuEq for 1.6 million ounces of contained gold equivalent metal (714koz Au, 35Moz Ag, 164kt Zn, 40kt Cu and 37kt Pb). This includes a high-grade component of 493koz AuEq grading 3.1g/t AuEq (cut-off >1.9g/t AuEq). The updated MRE is summarised by deposit group in Table 1, and Resource growth since 2022 is shown in Table 2. Table 1.

Importantly, all deposits present significant opportunities to further grow the Resource base, remaining open along strike and at depth. Full details of the MRE update were provided in the Company’s ASX Announcementxiv . Larger Scoping Study Following the release of the updated Mineral Resource Estimate on 30 July 2026, the Company engaged globally recognised engineering, consulting and project delivery firm Ausenco Services Pty Ltd (Ausenco) and leading global advisory firm WSP Australia Pty Limited (WSP) to work together to deliver the Larger Scoping Study for the Mt Carrington Projectxvi . The Study will update the following key inputs relative to the May 2026 Scoping Studyxvii : • the updated MRE, including a 69% increase in Indicated Resources to 19.3Mt; • plant throughput, assessing options above the 1Mtpa base case; • metal prices and concentrate payabilities; • processing costs and plant ramp-up assumptions; and • capital and operating cost estimates and financial metrics. Mine optimisation and mine scheduling work is underway with WSP, incorporating the updated MRE. Process engineering, cost estimating and financial modelling will be undertaken by Ausenco. The processing strategy is unchanged, with batch flotation of gold-dominant and silver-dominant deposits followed by concentrate blending to produce a saleable precious metal concentrate. The final product and marketing strategy also remain unchanged from the May 2026 Scoping Study. The Larger Study is expected to be completed in the December 2026 Quarter. Emu Prospect: Phase 1 Drilling Program Legacy completed a Phase 1 eight-hole diamond drilling program at the Emu Copper-Gold Prospectxviii during the Quarter. The Emu Prospect is a priority regional target identified as a discrete porphyry-epithermal target through the integration of historical geological mapping, surface sampling and recent airborne Mobile Magnetotelluric (MT) geophysics. The Emu target area contains the historical Emu Creek copper mine, originally worked as a shaft before an open cut was operated between 1966 and 1971. The completed program comprised eight diamond drillholes for a total of 1,600m across five drill pad sites. It provided the first modern drill test of the two targets defined by the airborne Mobile MT ASX: LGM SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB Page 4 of 16 survey: the Emu Porphyry Core, a deep, low-resistivity feature interpreted as a potential porphyry- style intrusive body; and the Emu Alteration Halo SE, a shallow zone of elevated resistivity interpreted as a silicified alteration halo. Copper is the primary target at Emu, where copper was mined historically. Core has been logged and samples have been submitted to the laboratory, with results awaited at Quarter-end. Further follow- up drilling is planned. Figure 1. Plan view of the Emu Copper-Gold Prospect showing drilling over soil geochemistry (Ag ppm) Mascotte Silver-Gold Prospect: Phase 2 Drilling A ten-hole Phase 2 diamond-cored drilling program commenced at the Mascotte prospect during the Quarterxix . The Mascotte Prospect is located approximately 3.5km south-east of the village of Drake within EL6273 and is defined by an area of significant historical workings, with the primary mineralised trend interpreted over approximately 1.3km of strike. The Phase 2 program will comprise an initial ten diamond-cored drillholes for a total of approximately 2,000m. Additional drill pads have been approved, providing flexibility to extend the program if warranted. Phase 2 steps out from the maiden Phase 1 program and is designed to test the structural and depth extensions of the Mascotte mineralised system, which remains open along strike and at depth. The program targets extensions of previously reported intercepts, including 40m at 1.0g/t Au from 151m, including 9m at 2.7g/t Au from 180m (MSDD001) and 18.3m at 237g/t Ag from 3m, including 9.1m at 394g/t Ag (PDMS005A).xx ASX: LGM SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB Page 5 of 16 Figure 2. Section view of the Mascotte Silver-Gold Prospect - MSDD001 drill hole showing completed and planned drill holes. Induced Polarisation (IP) Geophysics Survey Fender Geophysics undertook induced polarisation (IP) surveys at the Mascotte Prospect during the Quarterxxi , with data processing and 2D and 3D inversion modelling completed by Mitre Geophysics. The Mascotte survey comprised both Gradient Array IP (GAIP) and Dipole-Dipole IP (DDIP) configurations. The GAIP resistivity data defined a southwest-to-northeast-trending resistivity high (approximately 2,000 Ωm) through the middle of the survey area, with the historic Mascotte mine located on the southern edge of this resistive zone. The higher resistivity may reflect a lithological change or increased silicification. The GAIP chargeability data mapped several southwest-to-northeast-trending chargeability highs (>15mV/V) located primarily along the northern and southern margins of the resistive zone. The transition from the resistive corridor to less resistive rocks (~200 Ωm) along these margins may indicate structures or fluid pathways, with the elevated chargeability interpreted to reflect sulphide alteration along those structures. The DDIP results agree closely with the GAIP, with the chargeability highs mapped in the GAIP also imaged in the DDIP inversion sections. Two main chargeability zones were modelled on Lines 10700E and 10500E. The northern zone, centred at approximately 21200N, is the largest and strongest, with an amplitude exceeding 30mV/V in the 2D inversion model and a core at approximately 100 to 120m depth. The southern zone, at approximately 20900N, is also very strong at up to 30mV/V, but is smaller and shallower, with a core at approximately 60 to 80m depth. Both zones remain open to the northeast and continue to the southwest onto Line 10500E. Three-dimensional inversion of the DDIP lines confirms the continuity of these chargeability ASX: LGM SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB Page 6 of 16 zones between lines. Figure 3. Oblique 3D view (looking northeast) of the Mascotte DDIP 2D inverted chargeability sections with 3D chargeability iso-shells (26mV/V and higher). Drill holes shown are the 2025-2026 LGM drilling. The IP surveys have identified a northeast-trending resistive corridor flanked by several strong chargeability anomalies interpreted to reflect sulphide-bearing structures along the margins of the resistive zone. These anomalies are spatially associated with and extend beyond the known gold-silver mineralisation at Mascotte. Previous drilling returned intercepts including 40m at 1.0g/t Au from 151m (including 9m at 2.7g/t Au) in MSDD001 and 57m at 0.3g/t Au from 81m (uncut) (including 8m at 1.3g/t Au from 129m) in MSDD002. Comparison against previous drilling results indicates that none of the chargeability highs defined by the IP inversion models were drill tested. The strongest Mascotte chargeability anomalies, which exceed 30mV/V, therefore represent high-priority, untested targets for sulphide-hosted gold and silver mineralisation. Notably, several of the strongest chargeability targets do not appear to reach the surface and are interpreted to be “blind”. Targets of this kind cannot be found by surface rock sampling and can be easily overlooked, which is part of why they remain untested. Finding blind targets typically requires geophysics of this kind followed by drilling. The chargeability targets defined by the GAIP and DDIP surveys will be drill tested as part of the Company’s approved drilling program at Mascotte where drilling is currently underway. Drilling will aim to test the strongest, untested chargeability zones for sulphide-related and sulphide-hosted gold- silver mineralisation and to extend the known Mascotte mineralisation along strike and at depth.

ASX: LGM SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB Page 8 of 16 NiCo Young Project WSP Australia Pty Limited (WSP) has been engaged to complete an updated Mineral Resource Estimate (MRE) for the Company’s 100%-owned NiCo Young Nickel-Cobalt-Scandium (Ni-Co-Sc) Project in central New South Wales (NSW).xxii The updated MRE will include nickel and cobalt and, for the first time, will incorporate discrete, near- surface scandium domains which will be reported in accordance with the JORC Code 2012, producing a single combined Ni-Co-Sc Mineral Resource. The work program comprises compilation and validation of the historical scandium assay data and drillhole database, geological, weathering and scandium domaining, grade estimation and classification, and the derivation of updated cut-off grades and reasonable prospects for eventual economic extraction parameters. The current Inferred Mineral Resource, which reports nickel and cobalt onlyxxiii , is summarised in Table 3 below and remains current until the updated MRE is reported. Table 3.

Rockley Project During the Quarter, an Induced Polarisation (IP) survey was completed over the Crystal Hill Prospect at Legacy’s 100%-owned Rockley Projectxxv , 25km west of Oberon in NSW. Two-dimensional (2D) and three-dimensional (3D) inversion modelling of the survey data has defined three discrete zones of elevated chargeability (Table 4). The most significant of these is a north-north- west trending zone of approximately 800m strike extent that is coincident with the Crystal Hill soil geochemistry anomaly. None of the three zones has been drill tested. Table 4. Summary of the modelled chargeability targets defined by the 2026 Rockley IP survey. Positions are given in the local survey grid.

East 21050N 12200E ~200m 35mV/V Hosted within a resistive zone, unlike the other two targets. Chargeability in millivolts per volt (mV/V) measures the ability of the ground to hold an electrical charge and can be elevated in response to disseminated sulphide minerals, alteration, graphite, clay ASX: LGM SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB Page 9 of 16 or other lithological variation. North-West target: a strong chargeability anomaly of more than 40mV/V centred at approximately 200m depth at 10800E on Line 21950N, where the resistivity model also shows a change from resistive in the west to conductive in the east that is interpreted to reflect the schist and metabasalt contact mapped in the regional geology. Central target: a north-north-west trending linear zone of approximately 800m strike extent defined across Lines 21500N, 21050N and 20600N, with modelled chargeability of up to 45mV/V from approximately 100m depth. The zone is coincident with the Crystal Hill soil geochemistry anomaly and is considered the most prospective target defined by the survey. East target: a 35mV/V chargeable zone at 12200E on Line 21050N at approximately 200m depth. This target is distinguished from the other two by sitting within a resistive rather than a conductive zone. The Company is integrating the 2D and 3D inversion models with its geological mapping, structural interpretation, soil and rock chip geochemistry to refine and prioritise the three targets for drill testing. Drill testing of the three chargeability anomalies is under consideration and remains subject to drill planning, landholder access, statutory approvals and funding. Figure 5.
