Announcement PDF Gold, Silver, and Copper - Mt Carrington NSW, Australia Webinar Update Discovery and Development 21 May 2026 ASX: LGM Important Information The May 2026 Mt Carrington Scoping Study has been prepared to ascertain whether a business case can be made before proceeding with more definitive studies of Mt Carrington’s development viability. The Scoping Study is a preliminary technical and economic assessment of the potential viability of mineral extraction at Mt Carrington. The Scoping Study is based on low-level technical and economic assessments that are not yet sufficient to support the estimation of Ore Reserves. Further exploration and evaluation work, and appropriate studies, are required before any estimate of Ore Reserves can be made, or before any assurance of an economic development case. The Scoping Study is based on the material assumptions outlined in this announcement. These include assumptions about the availability of funding. While the Company considers all of the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the Scoping Study will be achieved. The Company has reasonable grounds to disclose a Production Target, which includes an amount of an Inferred Mineral Resources. For the Life of Mine, approximately 71% of the Life of Mine Production Target is in the Indicated Mineral Resource category, and 29% is in the Inferred Mineral Resource category. Legacy Minerals considers that Mt Carrington’s financial viability does not depend on the inclusion of Inferred Resources; the maturity of the project and historical production; the history of past Mineral Resource Estimations converting from inferred to indicated; and therefore, reasonable basis exists for disclosing a production target including Inferred Resources. There is a lower level of geological confidence associated with Inferred Mineral Resources, and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources, or that the Production Target itself will be realised. Investors are cautioned that the Scoping Study is at a scoping-level of confidence (-30% to +45% accuracy). Further study work is required to develop all project-modifying factors, including but not limited to mining dilution, ore loss, metallurgical recoveries, geotechnical parameters, hydrology and dewatering, closure, cost estimates, and environmental and social impacts. The Scoping Study is based on the material assumptions outlined in this announcement, including assumptions about the availability of funding. While Legacy Minerals considers all material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the Scoping Study will be achieved. To achieve the range of outcomes indicated in the Scoping Study, funding in the order of approximately A$220.5M (maximum expected cash drawdown, including working capital and contingency) will likely be required. The Scoping Study is based on the material assumptions outlined in this announcement. These include assumptions about the availability of funding. Legacy Minerals has a strong track record of raising funding as required on attractive terms, and a significant combined professional track record in the and development of resources projects. However, while Legacy Minerals considers all of the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the range of outcomes indicated by the Scoping Study will be achieved. To achieve the range of outcomes indicated in the Scoping Study, funding in the order of ~A$220.5 million will likely be required (inclusive of all capital, owners, and other costs associated with an Engineering, Procurement and Construction (EPC) contract, and all factored contingencies). This funding may take the form of debt and/or equity. Investors should note that there is no certainty that Legacy Minerals will be able to raise that amount of funding when needed. It is also possible that such funding may only be available on terms that may be dilutive to or otherwise affect the value of Legacy Mineral’s existing shares. It is also possible that Legacy Minerals could pursue other ‘value realisation’ strategies such as a sale, partial sale or joint venture of Mt Carrington. If it does, this could materially reduce Legacy Mineral’s proportionate ownership of the project. Given the uncertainties involved, investors should not make any investment decisions based solely on the results of the Scoping Study. This announcement has been prepared in compliance with the JORC Code 2012 Edition and the ASX Listing Rules. All material assumptions on which the forecast financial information is based have been included in this announcement.
