The Company’s vast ~7,000 km² Overland Uranium Project in South Australia shows strong uranium discovery potential, with initial drilling identifying opportunities for substantial near-surface and deeper deposits. Simultaneously, AR3's Koppamurra Rare Earths Project in South Australia and Victoria has secured important government support through a $5 million grant to accelerate development. With support from global advanced industrial materials manufacturer, Neo Performance Materials, AR3 is progressing toward a Pre-Feasibility Study and a demonstration facility, solidifying its role in diversifying global rare earth supply chains for the clean energy transition. With strategic projects and strong government support, AR3 is poised for significant growth in the critical minerals market. AR3 | Tribeca Future Facing Symposium | August 2026 1 Koppamurra: A new Australian source of Rare Earths Tribeca Future Facing Symposium AUGUST 2026 ASX: AR3 Disclaimer & Important Information The information in this announcement is in summary form and does not purport to be complete nor does it contain all the information in relation to the Company. It should be read in conjunction with the Company's other periodic and continuous disclosure announcements lodged with the ASX at www.asx.com.au. The Company does not purport to give financial or investment advice. No account has been taken of the objectives, financial situation or needs of any recipient of this document. The information in this announcement does not take into account the investment objectives, financial situation or needs of any recipient and does not constitute financial product advice. To the fullest extent permitted by law, the Company and its associates or any of its directors, agents, officers or employees do not make any representations or warranties, express or implied, as to the accuracy or completeness of any information, statements, opinions, estimates, forecasts or other representations contained in this presentation. No responsibility or liability for any errors or omissions from this presentation arising out of negligence or otherwise is accepted. Each party to whom this announcement is made available must make its own independent assessment of the Company and the announcement after making such investigations and taking such advice as may be deemed necessary. Any reliance placed on the announcement is strictly at the risk of such person relying on such announcement. All references to $ in this announcement are to Australian dollars unless stated otherwise. Some of the statements contained in this announcement are forward-looking statements. Forward looking statements include but are not limited to, statements concerning estimates of expected costs, statements relating to the advancement of the Company’s investments and other statements which are not historical facts. Although the Company believes that its expectations reflected in the forward-looking statements are reasonable, such statements involve risk and uncertainties, and no assurance can be given that actual results will be consistent with these forward-looking statements. Various factors could cause actual results to differ from these forward-looking statements include the potential that the Company’s projects may experience technical, geological, metallurgical and mechanical problems, changes in product prices and other risks not anticipated by the Company or disclosed in the Company’s published material. The Pre-Feasibility Study referred to in this announcement is a preliminary technical and economic assessment of the potential viability of producing a mixed rare earth oxide (MREO) product to support Mineral Resources and Ore Reserve of the Koppamurra Project. Those estimates have been prepared by a competent person in accordance with JORC Code 2012 and all production targets are based on those Mineral Resources and Ore Reserves and all material assumptions relating to those production targets and related forecast financial information are set out in the relevant market announcement (ASX announcement dated 25 June 2026). The production targets, related forecast financial information and other forward-looking statements referred to are based on information available to the Company at the time of release and should not be solely relied upon by investors when making investment decisions. Material assumptions and other important information are contained in this announcement. The Company cautions that mining and exploration are high risk and subject to change based on new information or interpretation, commodity prices or foreign exchange rates. Actual rates may differ materially from the results or production targets contained in this presentation. Further evaluation is required prior to a decision to conduct mining being made. Mineral Resource and Ore Reserve estimates are necessarily imprecise and depend on interpretations and geological assumptions, minerals prices, cost assumptions and statistical inferences (and assumptions concerning other factors, including mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors) which may ultimately prove to be incorrect or unreliable. Mineral Resource and Ore Reserve estimates are regularly revised based on actual exploration or production experience or new information and could therefore be subject to change. In addition, there are risks associated with such estimates, including (among other risks) that minerals mined may be of a different grade or tonnage from those in the estimates and the ability to economically extract and process the minerals may become compromised or not eventuate. The Company’s plans, including its mine and infrastructure plans, and timing, for the Project, are also subject to change. Accordingly, no assurances can be given that the production targets, financial forecasts, other forecasts or other forward-looking statements or information will be achieved. To achieve the development outcomes outlined in this announcement, AR3 estimates that funding of at least A$178 million will be required. There is no certainty that AR3 will be able to raise the required funding when needed, and any such funding may only be available on terms that may be dilutive or otherwise adversely affect shareholders. Cautionary Statement The Pre-Feasibility Study (“PFS” or “Study”) referred to in this presentation has been undertaken by Australian Rare Earths (“AR3” or the “Company”) in conjunction with various independent consultants, to determine the viability of the development at the Koppamurra Rare Earths Project in South Australia (“Project” or the “Koppamurra Project”). The PFS is based on technical and economic assessments of a level of accuracy commensurate with a prefeasibility study. The total Life of Mine Production Target (and forecast financial information derived from the Production Target) referred to in this announcement is underpinned by approximately 71% by Probable Ore Reserves and the remaining approximately 29% by Inferred Mineral Resources and have been prepared by Competent Persons in accordance with the requirements of the JORC Code (2012). There is a low 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 (or the forecast financial information) will be realised. The Company has satisfied itself that the Inferred Mineral Resources included in the Life of Mine Production Target are not the determining factor in project viability. The Project economics modelled without any Inferred Resources and only based on Ore Reserves retains a robust Post-Tax NPV8 of $652 million. The Inferred Mineral Resources included in the Life of Mine Production Target are allocated across the 12 year mine life with an average of 23% Inferred Mineral Resource across the first 10 years ranging from 2% to 33%. The expected payback period for the Koppamurra Project is less than one year. The Life of Mine Production Target and associated forecast financial information are based on assumptions and modifying factors which may prove to be inaccurate, and there is no certainty that the forecast outcomes will be achieved. The Company confirms that the Ore Reserves estimates, and Mineral Resources estimates have been prepared by Competent Persons in accordance with the requirements of the JORC Code. This presentation has been prepared in compliance with the JORC Code 2012 Edition (JORC 2012) and the ASX Listing Rules. All material assumptions on which Life of Mine Production Target and the forecast financial information have been provided in the relevant market announcement (ASX announcement dated 25 June 2026) and outlined in the JORC 2012 table 1 disclosures in the ASX release “Maiden Ore Reserves positions Koppamurra for development” 25 June 2026. This document contains forward-looking statements, including statements regarding production targets, forecast financial information, development plans and project economics. Forward-looking statements are subject to risks, uncertainties and assumptions, many of which are outside the control of the Company. These include, but are not limited to, commodity prices, exchange rates, regulatory approvals, funding availability and operating performance. While the Company considers all the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct or that the production target or estimated outcomes indicated by the PFS (such as the financial forecasts) will be achieved. The production target and estimated outcomes indicated by the PFS (such as the financial forecasts) are also subject to various risk factors. Given the uncertainties involved and detailed in this announcement, investors should not make any investment decision based solely on the results of the PFS.
