Investors should seek advice from their own financial, legal, tax and other independent advisers. The Company has prepared this document based on information available to it at the time of preparation. No representation or warranty, express or implied, is made as to the fairness, accuracy or completeness of the information, opinions and conclusions contained in this Presentation. Disclaimer ■ No party other than the Company has authorised, permitted or caused the issue, submission, dispatch or provision of this Presentation, or takes any responsibility for, or makes or purports to make any statement, representation or undertaking in this Presentation and there is no statement in this Presentation that is based on any statement by any other party.

Investment and Other Risks ■ There are a number of risks specific to the Company and of a general nature which may affect the future operating and financial performance of the Company and the value of an investment in the Company, including and not limited to the Company's capital requirements, risks associated with the reporting of resources and reserves estimates, development risk, construction risk, permitting risk, commodity price risk, operational risk and general market and economic conditions. ■ An investment in shares is subject to known and unknown risks discussed previously which impact the accuracy of Forward Statements. The Company does not guarantee any particular rate of return or the performance of the Company. Investors should have regard to these risk factors when making their investment decisions. Currency ■ All dollar values are in Australian dollars ($ or A$) unless otherwise stated. Authorisation ■ This Presentation has been authorised for release by the Board. Production Targets This Presentation includes production targets and forecast financial information derived from production targets. The production targets and forecast financial information are extracted from the Company’s ASX announcement dated 8 July 2026, titled “Bullabulling PFS Confirms High-Margin, Large-Scale Gold Mine” (PFS Announcement), which is available on the Company’s website www.minerals260.com.au The Company confirms that all material assumptions underpinning the production targets, and the forecast financial information derived from those production targets, in the PFS Announcement continue to apply and have not materially changed. Any potential future expansion of the Project's production capability is theoretical or conceptual only. The Company has not undertaken or completed sufficient work to determine whether any potential expansion of production outcomes detailed in the Pre-Feasibility Study referred to in this Presentation could be achievable or realised in the future. Cautionary Statement The PFS outcomes referred to in this Presentation assumes construction of a Stage 1 processing plant which has been designed and costed to support a 5Mtpa mining and processing operation. As such, all forecasted production and financial information presented in the PFS is based on the Company's anticipation of mining operations at that level of capacity. In addition, while the PFS considers some components being designed and constructed in Stage 1 with a 7.5Mtpa nameplate capacity, the Company has no present intention to operate the broader processing plant or undertake mining activities at the Bullabulling Gold Project at a production rate beyond 5Mtpa. Minerals 260 does not have reasonable grounds to determine that a potential expansion of the Project's operations are economically or technically viable. Any potential future expansion of operations beyond 5Mtpa would be subject to positive outcomes being reached under an expansion study. See the Company's indicative development timeline for further details as to its present estimation of commencement of such studies. There can be no guarantee by the Company that such expansion studies will result in the determination of the economic viability with respect to any potential future expansion of the Project, including the aspirational statement referred to above. JORC Code differs from reporting requirements in other countries It is a requirement of the ASX Listing Rules that the reporting of ore reserves and mineral resources in Australia comply with the JORC Code. Investors outside Australia should note that while ore reserve and mineral resource estimates of the Company in this document comply with the JORC Code, they may not comply with the relevant guidelines in other countries and, in particular, do not comply with (i) National Instrument 43 101 (Standards of Disclosure for Mineral Projects) of the Canadian Securities Administrators or (ii) Item 1300 of Regulation S-K, which governs disclosure of mineral reserves in registration statements filed with the US Securities and Exchange Commission. Information contained in this Presentation describing mineral deposits may not be comparable to similar information made public by companies subject to the reporting and disclosure requirements of other countries. You should not assume that quantities reported as “resources” in this Presentation will be converted to reserves under the JORC Code or any other reporting regime or that the Company will be able to legally and economically extract them.

Non-IFRS Financial Information ■ This Presentation includes certain financial measures and metrics that are not defined or recognised under Australian Accounting Standards (AASB) or International Financial Reporting Standards (IFRS) (collectively, Non-IFRS Measures). The Non-IFRS Measures used in this Presentation include, but are not limited to NPV (Net Present Value), IRR (Internal Rate of Return), Payback period, EBITDA (Earnings Before Interest, Tax, Depreciation and Amortisation), AISC (All-In Sustaining Cost), C1 cash cost, Operating cost per tonne processed. ■ These Non-IFRS Measures are used by the Company as supplementary measures of financial performance and project economics. They are provided to give investors additional insight into the potential economics of the Bullabulling Gold Project as assessed in the Pre- Feasibility Study (PFS) and should be read in conjunction with, and not as a substitute for, financial information prepared in accordance with AASB/IFRS. ■ Investors should note the following: ■ Not audited or reviewed: The Non-IFRS Measures set out in this Presentation have not been audited, reviewed or calculated in accordance with AASB/IFRS and have not been subject to review by an external auditor or independent accountant. ■ PFS-based estimates. The Non-IFRS Measures presented in this Presentation are derived from PFS-level financial modelling prepared by Snowden Optiro and the Company's technical advisers. They are estimates only and are subject to the material assumptions, qualifications and risks described in this Presentation and in the PFS Announcement released on 8 July 2026. They do not represent actual or forecast financial results. ■ Not comparable: The Non-IFRS Measures used in this Presentation may not be comparable to, or calculated in the same manner as, similarly labelled measures used by other companies, and accordingly should not be used as a basis for comparison between companies. ■ No reconciliation to IFRS: As these Non-IFRS Measures are derived from PFS financial modelling rather than historical financial statements, a reconciliation to AASB/IFRS financial measures is not practicable and has not been provided. ■ Gold price and exchange rate sensitivity: The NPV, IRR, payback period and EBITDA figures presented in this Presentation are based on the gold price and foreign exchange rate assumptions stated in this Presentation. They are sensitive to changes in those assumptions and actual outcomes may differ materially from those presented. ■ The Non-IFRS Measures should be considered in conjunction with the Forward Statements disclaimer set out in this Presentation. To the extent any Non-IFRS Measure constitutes prospective financial information, it is subject to the same qualifications and assumptions set out in that disclaimer. Forward Looking Statements This Presentation may contain forward-looking statements, guidance, forecasts, estimates, prospects, projections or statements in relation to future matters that may involve risks or uncertainties and may involve significant items of subjective judgement and assumptions of future events that may or may not eventuate (Forward Statements). Forward Statements can generally be identified by the use of forward-looking words such as “aiming”, "anticipates", "estimates", "will", "should", "could", “currently”, "may", "expects", "plans", "forecast", "target" or similar expressions. Forward Statements including references to updating or upgrading mineral resource estimates, future or near-term production and the general prospectivity of the deposits at the Bullabulling Gold Project (Project), likelihood of permitting the Project and taking a financial investment decision, among other indications, guidance or outlook on future revenues, distributions or financial position and performance or return or growth in underlying investments are provided as a general guide only and should not be relied upon as an indication or guarantee of future performance. In addition, these Forward Statements are based upon certain assumptions and other important factors that, if untrue, could materially affect the future results, performance or achievements expressed or implied by such information or statements. There can be no assurance that such information or statements will prove to be accurate. Key assumptions upon which the Company’s forward-looking information is based include, without limitation, assumptions regarding the exploration and development activities, receipt of timely approvals and permits, ability to obtain timely finance on reasonable terms when required in the future and contracting for development, construction and commissioning of any future mining operation on terms favourable to the Company, the current and future social, economic and political conditions and any other assumption generally associated with the mining industry.
