Forward-looking Statements This document contains “forward-looking information” and “forward-looking statements” which are based on the assumptions, estimates, analysis and opinions of management made in light of its experience and its perception of trends, current conditions and expected developments, as well as other factors that management of Westgold believes to be relevant and reasonable in the circumstances at the date that such statements are made, but which may prove to be incorrect.

Any such historical information is not represented as being, and is not, indicative of Westgold’s view on its future financial condition and/or performance, nor the future financial condition and/or performance of the merged group. 2 Important Notices and Disclaimer Ore Reserves and Mineral Resources The information in this presentation that relates to the Ore Reserves and Mineral Resources of Westgold has been extracted from the ASX announcement titled “2025 Mineral Resource Estimate and Ore Reserves " released to the ASX on 3 September 2025 and available at www.asx.com.au. Westgold confirms that it is not aware of any new information or data that materially affects the information included in that announcement, and that all material assumptions and technical parameters underpinning the estimates in that announcement continue to apply and have not materially changed. Westgold confirms that the form and context in which the Competent Persons findings are presented have not been materially modified from that announcement. The information in this presentation that relates to Westgold’s Exploration results and Mineral Resource Estimates is compiled by Westgold technical employees and contractors under the supervision of Mr. Jake Russell B.Sc. (Hons), who is a member of the Australian Institute of Geoscientists and who has verified, reviewed and approved such information. Mr Russell is a full- time employee of Westgold and has sufficient experience which is relevant to the styles of mineralisation and types of deposit under consideration and to the activities which he is undertaking to qualify as a Competent Person as defined in the Joint Ore Reserves Committee’s 2012 Australasian Code for Reporting of Mineral Resources and Ore Reserves (JORC Code) and as a Qualified Person as defined in the CIM Guidelines and National Instrument 43-101 - Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators (NI 43-101). Mr. Russell is a full-time employee as General Manager – Technical Services of Westgold and, accordingly, is not independent for purposes of NI 43-101. Mr Russell consents to and approves of the inclusion in this presentation of the matters based on his information in the form and context in which it appears. Mr Russell is eligible to participate in short and long-term incentive plans of Westgold. The information in this presentation that relates to Westgold’s Ore Reserve is based on information compiled by Mr. Leigh Devlin B.Eng. FAusIMM and who has verified, reviewed and approved such information. Mr. Devlin has sufficient experience which is relevant to the styles of mineralisation and types of deposit under consideration and to the activities which they are undertaking to qualify as a Competent Person as defined in the JORC Code and as a Qualified Person as defined in the CIM Guidelines and NI 43-101. Mr. Devlin is full-time senior executive of Westgold and, accordingly, is not independent for purposes of NI 43-101. Mr. Devlin consents to and approves of the inclusion in this presentation of the matters based on his information in the form and context in which it appears. Mr. Devlin is a full-time senior executive of Westgold and is eligible to and may participate in short-term and long-term incentive plans of Westgold as disclosed in its annual reports and disclosure documents. Mineral Resources, Ore Reserve Estimates and Exploration Targets and Results are calculated in accordance with the JORC Code. Investors outside Australia should note that while Ore Reserve and Mineral Resource estimates of the Company in this announcement comply with the JORC Code (such JORC Code-compliant Ore Reserves and Mineral Resources being "Ore Reserves" and "Mineral Resources" respectively), they may not comply with the relevant guidelines in other countries. The JORC Code is an acceptable foreign code under NI 43-101. Information contained in this release describing mineral deposits may not be comparable to similar information made public by companies subject to the reporting and disclosure requirements of US securities laws, including Item 1300 of Regulation S-K. All technical and scientific information in this release has been prepared in accordance with the Canadian regulatory requirements set out in NI 43-101 and has been reviewed on behalf of the Company by Qualified Persons, as set forth above. This presentation contains references to estimates of Mineral Resources and Ore Reserves. The estimation of Mineral Resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral Resources that are not Ore Reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral Resource estimates may require re-estimation based on, among other things: (i) fluctuations in the price of gold; (ii) results of drilling; (iii) results of metallurgical testing, process and other studies; (iv) changes to proposed mine plans; (v) the evaluation of mine plans subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals and licenses. Investment Risk As noted above, an investment in shares in Westgold is subject to investment and other known and unknown risks, some of which are beyond the control of Westgold. Westgold does not guarantee any particular rate of return or the performance of Westgold, nor does it guarantee the repayment of capital from Westgold or any particular tax treatment. Prospective investors should have regard to the risks outlined in this presentation when making their investment decision and should make their own enquires and investigations regarding all information in this presentation, including but not limited to the assumptions, uncertainties and contingencies which may affect future operations of Westgold and the impact that different future outcomes may have on Westgold. These risks, together with other general risks applicable to all investments in listed securities not specifically referred to, may affect the value of shares in Westgold in the future. There is no guarantee that the Westgold shares will make a return on the capital invested, that dividends will be paid on the Westgold shares or that there will be an increase in the value of the Westgold shares in the future. Accordingly, an investment in Westgold should be considered highly speculative and potential investors should consult their professional advisers before deciding whether to subscribe for Westgold shares. Effect of Rounding A number of figures, amounts, percentages, estimates and calculations of value in this presentation are subject to the effect of rounding. The actual calculation of these figures may differ from the figures set out in this presentation. Disclaimer Neither Westgold nor any of its advisers, affiliates, related bodies corporate, directors, officers, partners, employees or agents, have authorised, permitted or caused the issue, submission, dispatch or provision of this presentation and, except to the extent referred to in this presentation, none of them makes or purports to make any statement in this presentation and there is no statement in this presentation which is based on any statement by any of them. To the maximum extent permitted by law, Westgold and its advisers, affiliates, related bodies corporate, directors, officers, partners, employees or agents exclude and disclaim all liability, for any expenses, losses, damages or costs incurred by you and the information in this presentation being inaccurate or incomplete in any way for any reason, whether by negligence or otherwise.
