The information in this presentation is published to inform you about Zeotech Limited (“Zeotech” or the “Company”) and its activities based on information available to it as of the date of this presentation. Some statements in this presentation regarding estimates or future events are forward-looking statements. They involve risks and uncertainties that could cause actual results to differ from estimated results. All reasonable efforts have been made to provide accurate information, but we do not warrant or represent its accuracy, and we reserve the right to make changes to it at any time without notice. Hence, no representation is made as to the accuracy, completeness or reliability of the information.

ASX Listing Rule 5.23 The information in this presentation relating to exploration results for the Toondoon Project is extracted from the following announcements entitled ‘ZEO Acquires High-Grade Kaolin Project within Approved ML’ released to the ASX on 23 August 2021, ‘Notice of General Meeting/Proxy Form (Part 2 of 2) Ausrocks Mineral Estimates Report’ released to the ASX on 27 July 2022 and ‘Land Purchase Agreements signed Accelerate Toondoon Project’ released on to the ASX on 8 December 2022 and AusPozz Project Preliminary Feasibility Study released to the ASX on 24 June 2025, which are all available on the Company's website www.zeotech.com.au The Company confirms that it is not aware of any new information or data that materially affects the information included in the original market announcements, and that all material assumptions and technical parameters underpinning the estimates in the original market announcements continue to apply and have not materially changed. The Company confirms that the form and context in which the competent person’s findings are presented have not been materially modified from the original market announcements. Cautionary Statement The PFS referred to in this presentation was undertaken to assess the technical and economic viability of the AusPozz Project. The study aims to identify the preferred mining, processing, and infrastructure requirements, but it is not final. Further evaluation work, including a Definitive Feasibility Study (DFS), is required before the Company can provide assurance of an economic development case. This PFS is more than a preliminary technical and economic study given the work undertaken for the study, but it is not advanced sufficiently to support the estimate of Ore Reserves, and further technical work, including additional drilling and feasibility-level assessments, is planned to resolve the outstanding Modifying Factors and support a future Ore Reserve classification or provide any assurance of an economic development case. The Production Target referred to in this presentation is based on this PFS and supported solely by Measured and Indicated resources and not an Ore Reserve. Zeotech has concluded that it has reasonable grounds for disclosing a Production Target; however, there is no certainty that the Production Target or the economic assessment will be realised. The information in the PFS that relates to metallurgical results and processing assumptions is based on preliminary test work and should not be considered definitive. Additional test work, including vendor testing, is required to confirm the technical and economic viability of the proposed process flowsheet and product specifications. The PFS is based on the material assumptions described in the announcement on 24 June 2025 entitled “AusPozz Project Preliminary Feasibility Study” and summarised in the Summary of Material Assumptions and Summary of Modifying Factors in Appendix 1. These include assumptions about the availability of funding and the pricing received for the Company’s AusPozz and Kaolin DSO products. 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 PFS will be achieved. To achieve the range of outcomes indicated in the PFS, funding in the order of $95 million, plus working capital, will likely be required. Investors should note that there is no certainty that the Company will be able to raise the 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 the Company’s existing shares. It is also possible that the Company could pursue other ‘value realisation’ strategies such as a sale, partial sale, or joint venture of the project. If it does, this could materially reduce the Company’s proportionate ownership of the Project. Given the uncertainties involved, investors should not make any investment decisions based solely on the results of the PFS. DisclaimerFor personal use only
