Announcement PDF ASX ANNOUNCEMENT 6 SEP 2023 Artificial Intelligence Partner Earth AI Drilling Nickel-Copper-PGE Targets at the Fontenoy Project Legacy Minerals Holdings Limited (ASX: LGM, “LGM”, “the Company” or “Legacy Minerals”) is pleased to announce the commencement of diamond drilling by its exploration alliance partner, Earth AI at the Fontenoy Project, NSW. Rig Mobilised and Onsite • • Earth AI’s diamond drill rig has arrived onsite at Fontenoy and drilling is underway. 3,600m of diamond drilling has been approved by the Resource Regulator (NSW Government) • This includes up to six diamond holes at approximately 600m per hole. Significant Drilling Campaign Underway • • • • Earth AI has been implementing its artificial intelligence deposit targeting system at Fontenoy and has generated a range of drill targets across the tenement. Drilling will be targeting the recently identified nickel-copper sulphides at the Project i,1 with the identification of nickel sulphides at surface the first known occurrence in the district. NSW is known to host nickel laterite deposits, however nickel sulphide systems are rare and are greatly prized for their potentially higher grades and lower extraction costs. The drilling will also follow up on historical copper and gold intersections including ii: • 79m at 0.27% Cu from 1.5m and 22m at 0.67g/t Au and 0.34% Cu Drilling Timeframes The drill program is expected to run for two months with results expected later in the year.

Following the identification of nickel-iron sulphide mineralisation in fresh rock in June by Earth AI, the team has moved rapidly to get drilling underway to test this newly identified mineral style. The ultramafic belt that hosts Fontenoy is widely known for is nickel laterite systems which are some of the biggest nickel and cobalt deposits in Australia. Earth AI’s new search for nickel-copper sulphides and PGE’s (platinum group elements) is frontier exploration in this part of NSW. Excitingly this potential for nickel-sulphides has remained untested until now with little previous exploration or drilling in the priority target areas. In addition to the imminent drilling at Bauloora, this drill campaign at Fontenoy provides Legacy Minerals shareholders with another fully funded exploration front and discovery opportunity.” Planned Diamond Drilling Figure 22: Fontenoy map showing the recent rock chip locations and historic drilling iii SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 3 of 8 The Earth AI team have steadily worked on building a greater understanding of the Fontenoy geology. Diamond drill testing is now underway to test the new geological thinking and targets that have been defined across this project. Detailed mapping, petrographic studies and soil and rock chip analysis have been completed in the latest field campaigns. In following up indications of anomalous copper, nickel and platinum group element mineralisation, pentlandite (nickel-iron sulphide) has been identified for the first time in fresh rock. Figure 3: Earth AI field team conducting soil sampling at Fontenoy (left), and rock sample 5996 (top right), and nickel sulphides (pn - pentlandite), copper sulphides (cpy - chalcopyrite) confirmed in serpentinite/gabbro through SEM and petrographic analysis (bottom right)i. Ni-laterites have been previously identified at Fontenoy and were the focus of previous nickel-cobalt exploration drilling. These residual deposits were thought to have been formed as a results of serpentinite weathering solely and as such the exploration for nickel-iron sulphides did not occur. The recognition of Ni-sulphides in association with copper and PGEs (platinum group elements) however highlights the prospectivity of the Fontenoy Project for Ni-Fe sulphide deposits and presents an opportunity for the Company to be the first to apply exploration methods and systems thinking for this style of mineralisation. Nickel in New South Wales There are numerous nickel occurrences located in three main NSW ultramafic belts iv. These occurrences are predominantly in the form of residual nickel-cobalt laterites, less commonly hydrothermally-enriched nickel sulphide deposits, and orthomagmatic nickel sulphide deposits in layered mafic and ultramafic bodies.

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 platinum group element (PGE) mineralisation. Disseminated and veined copper-gold mineralisation hosted within the Yandilla Volcanics has a strike length of approximately 8km. Mineralisation here is interpreted to represent McPhillamys-style volcanogenic hosted massive sulphide (VHMS) mineralisation, however the potential for intrusion related copper-gold mineralisation is being investigated. The Project has had a significant amount of surface geochemical work completedii with extensive soil sampling focused on the Yandilla Volcanics and a bulk cyanide leach stream sediment survey conducted across the tenement. Rock chip sampling has also been conducted across the tenement for Mn and Talc assessment and for Au-Cu mineralisation in the Yandilla Volcanics and Warrego Diorite. This work defined an 8km long Cu and Au soil anomaly centred over the Yandilla Volcanics with rock chips grading up to 0.73g/t Au and 0.47% Cu. A dipole-dipole induced polarisation (DDIP) survey has been completed at 200m and 800m line spacing along the length of the Yandilla Volcanicsii. Further to this, ground electromagnetic (EM) survey traverses and airborne EM at 150m line spacing has also been completed by earlier explorers. Induced polarisation (IP) surveying highlighted several known zones of Cu and Au mineralisation with a number of anomalies yet to be drilled. SIGN UP TO LEGACY MINERALS’ INTERACTIVE INVESTOR HUB ASX: LGM Page 5 of 8 A total of 16 diamond core holes for 4,014 metres and an additional 28 reverse circulation percussion (RC) drill holes for 1,667m were historically completedii. Drilling has confirmed soil anomalism is associated with broad Au-Cu mineralisation intersected along the entire 8km strike and provides encouragement for a number of drill ready target zones. Historical Drill intercepts at the Project includeii: 1-2-10D: 79m at 0.27% Cu from 1.5m WRC9: 22m at 0.67g/t Au and 0.34% Cu from 20m WRC21: 24m at 0.17g/t Au and 0.24% Cu from surface WRC3: 26m at 0.44g/t Au and 0.11% Cu from surface 1-2-15D: 14m at 0.72g/t Au and 0.37% Cu from 108m The large amount of historical data has provided Earth AI with significant base of information to utilise in their artificial intelligence and machine learning software for the delivery of compelling drill targets in a data rich environment. Earth AI Exploration Alliance Legacy Minerals signed an Exploration Alliance Agreement (Agreement) with Earth AI covering its Fontenoy (EL8995) tenement (Strategic Alliance) viii. The Strategic Alliance allows for a co-funding model, whereby Earth AI will contribute up to $4.5M AUD of total exploration costs across the tenement over a two-year period, with an option to extend for a further year. Subject to a qualifying drilling intersection (as defined within the Agreement) being subsequently identified, Earth AI Pty Ltd is entitled to a net smelter return royalty (Royalty) up to 3% in connection with a to be agreed upon area surrounding the discovery (Area of Interest). Legacy Minerals will retain 100% ownership over the tenement covered under the Agreement. Legacy Minerals is under no obligation to explore, develop or mine the tenement during the period of the Strategic Alliance. However, whereafter the second anniversary of the Royalty Trigger Date, if no mineral resource has been defined and the combined annual exploration development and mining expenditure in the Area of Interest falls below $250,000 USD, Earth AI will have the option to assume operational control and buy the Royalty Tenement that overlaps with the single Area of Interest under the Minerals Royalty Deed, for a cash purchase price equal to $1,000,000 USD plus a 2% net smelter royalty granted to the Legacy Minerals. Earth AI Exploration Strategy Earth AI is a vertically integrated metals exploration company based in San Francisco, USA. It’s 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.
