Management comment Legacy Minerals CEO & Managing Director, Christopher Byrne said: “The Thomson Project presents a rare, unexplored belt-scale gold and copper search space across 5,500km2 with a multitude of high-quality and untested ‘bullseye’ magnetic and gravity targets. As part of our plans to fast track a potential discovery we are excited to implement Fleet Space’s end-toend mineral exploration solution driven by space and 3D artificial intelligence ExoSphere modelling. “Fleet Space’s real-time 3D ANT surveys have rapidly become an important new exploration tool that is being utilised by major miners, including Barrick and Anglo Gold Ashanti, to target undercover discoveries. It provides a systematic dataset that when combined with regional gravity and magnetic surveys helps prioritise areas for drill testing.” “Based on our consideration that the Southern Thomson region is one of the most under-explored orogens in Australia, we staked a significant position in line with the belief that the next major new mineral province will be undercover and is yet to be found. “Using this latest cutting-edge technology, Legacy Minerals is attempting to make a major discovery in the district and we are moving quickly with the survey planned to commence in November with results expected within this quarter.” Thomson – Belt scale Intrusion-Related Gold and Copper Project Figure 2: Project overview showing EL9190, EL9194, ELA6777 and examples of “bullseye” magnetic targets (inset). SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 3 of 7 Located west of Bourke, the Thomson Project covers 5,500km2 of tenure under granted and pending exploration licenses, securing a belt-scale exploration opportunity for Legacy Minerals shareholders. Legacy Mineral’s is now exploring across nine projects in NSW, with four under farm-in and joint venture agreements covering more 8,000km2 of tenure. The Thomson Project is located near the southern margin of the Thomson Orogen nearby the interpreted contact with the Lachlan Fold Belt and the Delamerian Orogen. The Thomson Orogen covers a large area of Queensland and north-western New South Wales, mostly under cover of the Mesozoic Eromanga Basin. The dominant basement rocks are interpreted to consist of Cambrian to Ordovician volcanics, metamorphosed turbidite, siltstone, and slate that are intruded by Silurian to Devonian felsic and mafic igneous rocks. • • • Several deep stratigraphic drillholes, such as Tongo1, Laurelvale 1, completed by the NSW Geological Survey (GSNSW). Historic drillholes completed by previous exploration companies. The incorporation and interpretation of regional geophysical data (aeromagnetic, gravity and seismic) conducted by the GSNSW with geology logged in drill holes. The Thomson Project is covered by younger sediments that ranges up 280m thick. These sediments are part of the Eromanga and the Surat Basin cover sequences. This cover has historically, in part, deterred exploration and has limited the realisation of the Thomson Orogen’s mineral potential. Importantly, historical work indicates that this cover sequence is geophysically transparent with a number of the key geophysical targeting methods such as magnetics and gravity providing highly useful and important data sets. The GSNSW has suggested that the basement rocks within the Thomson Orogen have the possibility to hold similar mineral potential to the adjoining belts, including the base metal and gold endowment of the Lachlan Orogen to the south which is over 80Moz gold and 13Mt copper viii. A series of major, belt-scale faults are observable that may act as major fluid flow conduits during both early extensions and later deformation of the belt. 7F The survey is expected to start quarter four this year with interpretation expected within a few weeks of completion. This interpretation and 3D model will be used in conjunction with existing geophysical, drilling, and geochemical datasets to define drill targets for testing. About Fleet Fleet Space Technologies, Australia’s leading space exploration company based in Adelaide, is revolutionizing critical mineral discovery with its end-to-end mineral exploration solution, ExoSphere, which combines the company's proprietary satellite network, 3D multiphysics, and AI to image mineral systems in real-time. Over 40 leading exploration companies like Rio Tinto, Barrick Gold, and Core Lithium have used ExoSphere’s real-time 3D subsurface imaging on projects across five continents. ExoSphere’s vertically integrated technology stack has unlocked hyper-scalable, predictive, and lowimpact exploration capabilities worldwide. Recently, Fleet Space conducted the world’s largest realtime 3D ANT survey with Inflection Resources across 1800km2 in the Macquarie Arc, announced plans to deliver the world’s highest real-time 3D ANT survey between 3900-4700 meters above sea level at Salares Norte in Chile with Gold Fields, and delivered real-time 3D imaging on copper porphyry complexes across 1,150km2 of Barrick Gold’s Reko Diq project. Building on its exponential growth and sustained innovation in space technologies, Fleet Space was named “Australia’s Fastest Growing Company” by the Australian Financial Review in 2023, winner of the Innovation category at the 2024 Mining Technology Excellence Awards, and received the Climate Impact Technology Award at the Banksia Foundation’s 35th National Sustainability Awards. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 4 of 7 Example of Thomson Project Targets F1 Anomaly ix 8F A fence line of three Reverse Circulation and Diamond core holes was completed at the F1 anomaly. Drilling intercepted an I-type intrusive granodiorite with hydrothermal alteration was noted as occurring with pyrrhotite, minor chalcopyrite and molybdenite intergrown with coarse muscovite, interstitial to igneous quartz, feldspar and biotite, within granodioritic host rocks. The easternmost drillhole (F1DD01), passed through anomalous molybdenum (up to 0.2% Mo) as well as other IRG pathfinders including Bi, As (up to 1%) and Au (up to 0.24g/t). The overall pattern between the three drillholes suggests a pathfinder zonation in the F1 anomaly, pointing to potential for high gold zones in association with magnetic high responses, outside the centre of the intrusion. Modelling indicates the historical drill holes did not test the discrete magnetic high anomaly. H1 Anomalyix A discrete magnetic high where regional aeromagnetics suggests the anomaly is underlain by a large intrusive. Drilling intersected significant fluorite in veins indicating the influence of igneous fluids and hydrothermal mineralisation. Disseminated magnetic pyrrhotite becomes more abundant towards the bottom of the hole corresponding to increasing Zn anomalism. Modelling indicates the magnetic target was not tested. CUT-B Anomalyix The coincident gravity high and magnetic high anomaly shows the close spatial relationship between magnetic material and dense material located in a favourable structural position. Historical drilling appears to have missed the magnetic anomaly however mineralised veins were noted with assays up to 113g/t Ag, 0.5% Cu and 4.2% Zn. These veins are within a 300 m zone of strong carbonate and silica alteration indicative of a large, metalliferous, hydrothermal system which the Company interprets to have not been tested.
