Management comment Legacy Minerals CEO & Managing Director, Christopher Byrne said: “Legacy Minerals is pleased to see the results of the great work completed to date by Earth AI in unpacking the palladium, platinum, gold and copper potential of the Fontenoy Project. The latest results build Earth AI’s confidence in the continuity, scale and overall potential of this mineralised system. The known mineralised footprint is now 2km2 in size and has geochemical and geophysical indicators that suggest strong potential for this to further grow and potentially host higher grade zones similar to those identified in the last round of drilling. Importantly, the drill rig is again on site and drilling with three holes planned for completion before the end of the year. Combined with the drilling now commenced at Bauloora, for the Company it is an exciting end to the year with multiple discovery opportunities underway.” Diamond Drilling Earth AI completed two diamond-cored holes for a total 1,196 metres earlier this year. The holes were drilled at the Fontenoy Project to test the interpretation of a mafic intrusive complex with the potential to host magmatic related PGE and nickel-copper sulphide related mineralisation. Initial observations of the assay data indicate PGE mineralisation is dominantly occurring within and immediately underlying a high MgO core zone (>33% MgO) and sulphide development within this lower zone. This lower zone may reflect a favourable zone for PGE development. This is encouraging as it is consistent with the general model for magmatic Ni-Cu-PGE type mineral systems such as the Norilsk deposit iii. 2F Figure 2: Drill hole cross-section and geological interpretation of recent drilling (*no cut-off grade).

Drill hole EFO10D was drilled to target beneath the large 3E PGE in soil anomaly. Drilling intercepted ultramafic and mafic units having out-of-sequence emplacement with texitic appearance as a result of intermingling of the mineral phases and/or variations in mineral compositions and grain size, indicative of a complex magmatic process. Ultramafic units are variably altered to serpentinite, and PGE mineralisation is mostly confined to the fine-grained dunite cumulate units. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 4 of 16 Significant drilling intercepts included: • 360m at 0.12g/t 3E PGE from the surface (no cut-off grade), including; o 44m at 0.15g/t 3E PGE from surface, o 14m at 0.35g/t 3E PGE from 72m, o 22m at 0.29g/t 3E PGE from 116m, o 28m at 0.16g/t 3E PGE from 142m. Drill hole EFO9D was drilled to target beneath elevated 3E PGE soil anomalism on the interpreted contact of the Moonbilleen Gabbro and undifferentiated serpentinites. Drilling again intercepted an ultramafic–mafic magmatic complex showing distinct zonation with PGE mineralisation generally occurring within and at the base of the ultramafic units. Significant drilling intercepts included: • 100m at 0.13g/t 3E PGE from 64m (no cut-off grade), including; o 20m at 0.27 3E PGE from 128m. While NSW is known to host major laterite deposits, hosting nickel-cobalt and scandium, magmaticrelated nickel-copper-PGE sulphide systems are a newly recognised system. This style of deposit is rare and greatly prized for potentially higher grades, a potential suite of valuable metals and lower extraction costs. The Fontenoy Project has been drilled historically with companies targeting the potential for shallow nickel-laterite deposits. Historical explorers had not tested the potential for PGE’s or magmaticrelated nickel-copper sulphide mineralisation. Earth AI implemented its artificial intelligence deposit targeting system at Fontenoy, successfully generating a range of drill targets across the tenement. Through ground-truthing, the potential for magmatic-related nickel-copper-PGE mineralisation was identified. Earth AI’s subsequent drilling was focused on testing this hypothesis at the Project. The identification and confirmation of this style of mineralisation in drilling, including wide zones of disseminated PGEnickel-copper mineralisation, is the first in the district and it is believed that this represents the discovery of a new style of mineralisation in the Lachlan Fold Belt of NSW. Historical drill intercepts at the Project include v: 4F 1-2-10D: WRC9: WRC21: WRC3: 1-2-15D: 79m at 0.27% Cu 22m at 0.67g/t Au and 0.34% Cu 24m at 0.17g/t Au and 0.24% Cu 26m at 0.44g/t Au and 0.11% Cu 14m at 0.72g/t Au and 0.37% Cu from 1.5m from 20m from surface from surface from 108m Earth AI Exploration Strategy Earth AI is a vertically integrated metals exploration company based in San Francisco, USA. Its NSW based operations are located at Young, 15km from Legacy Minerals’ Fontenoy tenement. Earth AI plans to implement its artificial intelligence deposit targeting system to generate drill targets across the tenement. Once identified, Earth AI will follow up with on ground geophysical and geochemical work before drill testing. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 5 of 16 About Fontenoy The Fontenoy Project contains a number of prospective units within the Project area which include the Yandilla Volcanics, Warrenoy Diorite and ultramafic rocks of the Wambidgee Serpentinite for copper-nickel and cobalt. Stratabound manganese mineralisation occurs in the Cambro-Ordovician Jindalee Group, while the Wambidgee Serpentinite contains a number of chromite deposits, and this differentiated ultramafic sequence is prospective for both chromite and PGE mineralisation. Disseminated and veined copper-gold mineralisation hosted within the Yandilla Volcanics has a strike length of approximately 8km. Recent diamond drilling has returned magmatic-related PGEs: EFO7D: 120m at 0.3g/t 3E PGE from 298m including: 10m at 1.2g/t 3E PGE, 0.2% Ni and 891ppm Cu from 388m. Historical drilling has confirmed that Au-Cu soil anomalism is associated with broad gold-copper mineralisation intersected along the entire 8km strike and provides encouragement for several drillready target zones. Historical drill intercepts at the Project include vi: 5F 1-2-10D: WRC9: WRC21: WRC3: 1-2-15D: 79m at 0.27% Cu 22m at 0.67g/t Au and 0.34% Cu 24m at 0.17g/t Au and 0.24% Cu 26m at 0.44g/t Au and 0.11% Cu 14m at 0.72g/t Au and 0.37% Cu from 1.5m from 20m from surface from surface from 108m Nickel and PGE’s in New South Wales There are numerous nickel occurrences located in three main NSW ultramafic belts vii. These occurrences are predominantly in the form of residual nickel-cobalt laterites, less commonly hydrothermally-enriched nickel sulphide deposits, and rare magmatic nickel sulphide deposits in layered mafic and ultramafic bodies. 6F Figure 4: Significant projects, joint ventures, and nickel occurrences within the major ultra-mafic and mafic belts of NSW 2023 viii, ix, x 7F 8F 9F SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 6 of 16 Approved by the Board of Legacy Minerals Holdings Limited.

All intercepts are down hole widths only, true widths are not calculated. Appendix 1 – JORC Code, 2021 Edition Table 1 Section 1 Sampling Techniques and Data Criteria JORC Code Explanation Commentary 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. Diamond drilling was used to obtain HQ (diameter: 63.5) and NQ sized (diameter: 47.5mm) drill core for geochemical sampling. Interval spacing was 2 m with rare variance to adhere to geological contacts and alteration. Diamond drill core provided a high-quality sample that was logged for lithological attributes. 0.6m - 2m sample intervals were collected from the core trays. DD core samples have been half cut with an automatic core saw. Sampling Techniques Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. 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., Samples were submitted to ALS Geochemistry Pooraka SA for laboratory analysis. Sample preparation used industry standard methods of drying, jaw crushing and pulverizing to -75 microns (85% passing) (ALS code PUL-21 and PUL-22). Samples were analysed by ALS methods PGM-ICP23 and ME-MS61R. No other measurement tools have been used in the holes. The hole was not surveyed. The core was unoriented. Sampling was undertaken using sampling protocols and QAQC procedures in line with industry best practice. Due to the earlystage nature of exploration, no field duplicates or certified reference standards were submitted. The drill core was unoriented. The drill core was cut by Earth AI staff and trained staff of RME Geological Services Pty. Ltd., NSW. Diamond drilling was used to obtain drill core for geochemical sampling. After cutting, half core sampled in 0.6m-2m intervals were sent for analysis. Samples were submitted to ALS Geochemistry Pooraka SA for laboratory analysis.

Samples were analysed by ALS methods PGM-ICP23 and ME-MS61R. Assay standards, blanks and duplicates were analysed as part of the standard laboratory analytical procedures. Drilling techniques Drill type (e.g., core, reverse circulation, open‐hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g., core diametre, triple or standard tube, depth of diamond tails, facesampling bit or other type, whether core is oriented and if so, by what method, etc). Method of recording and assessing core and chip sample recoveries and results assessed. Drill sample recovery 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. 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. Logging Sub‐sampling techniques and sample Diamond drill techniques were used to obtain HQ sized core (diameter: 63.5mm) on average for the initial 100 m and NQ sized core (diameter: 47.5mm) for the remainder of the hole. Drill recovery was conducted by measuring core lengths and comparing rod string lengths during drilling. Core blocks were used to mark measured rod intervals. Meter marks were measured against core blocks and sampling intervals were taken according to the meter marks. Various diamond drilling additives (including muds and foams) have been used to condition the drill holes to maximise recoveries and sample quality. Drill core samples were cleaned at the drill site to remove drilling fluids and cuttings to present clean core for logging and sampling. There was no significant loss of material reported in the mineralised parts of the diamond core that was considered to bias samples. All drill holes undertaken have been logged in full, from a visual basis, recording lithology, texture, alteration and mineralisation. Systematic geological logging was undertaken. Data collection where appropriate included: • Nature and extent of lithologies. • Relationship between lithologies. • Texture, alteration and mineralisation • Amount and mode of occurrence of minerals. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Logging was both qualitative and quantitative capturing downhole depth, lithology and features of the sample. The total length and percentage of the relevant intersections logged. All drill holes were logged in full. If core, whether cut or sawn and whether quarter, half or all core taken. Diamond drill core was cut using conventional automatic core saw in ½ for NQ and HQ core. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 11 of 16 preparation The diamond core was consistently sampled ½ for NQ and HQ core with remaining ½ retained/stored in core trays. A sample size of 0.6m to 2m intervals, weighing between 3 and 5 kg were collected. If non‐core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. This size was considered appropriate, and representative of the material being sampled given the width and continuity of the intersections. Not applicable as results were from core drilling. Drill core was cut in half along the length and the total half core submitted as the sample. This procedure meets industry standards where 50% of the total sample taken from the diamond core is submitted. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Samples were dried, crushed and pulverized to produce a homogenous representative sub-sample for analysis. Samples undergo a dry crush of 90% passing 2mm with additional pulverising to a grind quality of 85% passing 75μm (ALS code PUL21 and PUL-22). Sample preparation was of industry standard. Core sample intervals were based on a nominal, 0.6m to 2m spacing. Quality control procedures adopted for all subsampling 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. All samples were dried and pulverised before analysis. Pulverisers were washed and fineness checks were routine, to ensure grind size as per the QAQC undertaken by the external laboratory. To ensure adequate preparation at the pulverisation stage samples were split to weigh less than 3kg. The remaining half-core was stored and allowed assay values to be viewed against the geology; and, where required, further samples may be submitted for quality assurance. Quarter core resampling may be completed in zones where appropriate. The sample size was considered appropriate for the mineralisation style and analytical techniques used. Samples undergo a spectral scan using the TerraSpec® 4 HR spectrometer. Samples were analysed for a Multi-Element Suite (48 element) Analysis by ICP-MS (MEICP61) following a four-acid digest. The Pt, Pd, Au analysis was carried out via standard lead fire assay with ICP-AES finish. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 12 of 16 Fire Assay is an industry-standard for Pt, Pd, Au and it is considered appropriate as a first-pass analysis.

Whether sample compositing has been applied. Certified Reference Materials/standards, blanks and duplicates were inserted to assess the assaying accuracy of the external laboratory for QAQC protocol. Techniques used for the early-stage nature of the Project were considered total. No geophysical tools were used to determine any reported element concentrations. No pXRF results are reported for drill hole samples. Laboratory internal procedures were to ensure grind size of 85% passing -75μm was being attained. Laboratory QAQC for assay analysis involved the use of internal lab standards using standards, blanks, and duplicates. All samples were analysed by an independent laboratory and verified by Earth AI staff and reviewed by Legacy Minerals personnel. No twinned holes have been completed in this drill program. Primary results certified by ALS Geochemistry were saved within a Company database. Raw data files were saved separately. Reviews of the data which encompasses geological logs, sample details, QA/QC insights and general geological interpretation of data was saved locally and uploaded to a database. No adjustments to assay data were undertaken. Drill hole collars were located using an iPhone dual frequency GPS with an accuracy of +/- 5m. No down hole surveys were undertaken. Downhole depths were in meters from surface. The grid system used was GDA94, zone 55 Elevation was recorded using an iPhone dual frequency GPS with an accuracy of +/- 10m. The spacing and distribution of holes was not relevant to the drilling programs which are at the exploration stage rather than definition drilling. Drill holes were preferentially located at those areas considered most prospective. Data spacing and distribution was appropriate for this stage of exploration. No Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied to exploration data being reported. Core was cut in ½ sections using a core saw and sampled in 0.6m-2m intervals. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 13 of 16 Whether sample compositing has been applied. Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. Orientation of data in relation to geological structure 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 Audits or reviews The measures taken to ensure sample security. The results of any audits or reviews of sampling techniques and data. No sample compositing was applied to diamond drill core. Drillholes were oriented between 60 - 75o from horizontal and 98 - 258 true north azimuth. No orientation tool was used during drilling and, as such, structural orientation was not completely possible. The orientation of key structures may be locally variable and any relationship to mineralisation has yet to be identified. If orientation of drilling relative to key mineralised structures or lithology has introduced sampling bias is unknown. Orientation of the mineralisation and structural trends was interpreted by previous drilling and outcrop. The orientation of sampling was considered approp
