Assays pending The grades of Tb & Dy in all of ABx’s rare earth resources are the highest of any ionic adsorption clay deposit in Australia and amongst the highest globally The lightweight rig is designed to have no impact on the cleared grazing land where these rare earths occur near surface, typically starting at 0.5 metres depth Pursuant to approvals from government and landholders, ABx Group Limited (ASX: ABX) has commenced drilling to expand the high grade T8 rare earth elements (REE) mineralisation that ABx’s scout drill campaign discovered in May 20251 - see Table 1, Figures 1 to 4. The first 3 holes have encountered the target horizon at surface, within 0.5 metres depth. Table 1: REE discovery hole TB008 in tenement EL27/2025. Hole ended still in the mineralised layer ABx’s Tasmanian rare earth projects are suited to early low cost production because they are shallow, ionic absorption clay type of rare earth resources enriched in the most critical rare earths dysprosium (Dy) and terbium (Tb). ABx has strong relationships with planned processing operations in the USA, such as Ucore.2 Dr Mark Cooksey, Managing Director and CEO of ABx Group, commented: “ABx is excited to be finding extensions of this shallow target horizon that hosts the T8 high grade rare earth mineralisation. ABx’s REE mineralisation in northern Tasmania is exceptionally high grade in Dy & Tb, which is potentially globally significant and unmatched in Australia. ABx is investigating a low cost, low impact method of rapidly developing this rare earth province. “China’s restriction on exports of critical heavy rare earths, especially Dy & Tb, sends a clear message to the global market and ABx is in a unique position with its Dy & Tb-rich shallow clay- hosted rare earth deposit in a stable jurisdiction. Dy & Tb are vital for many products including modern cars, phones, military technologies and offshore wind turbines. This is recognised by the industry, for example our MoU to supply rare earth feedstock to Ucore, which is planning a Strategic Metals Complex in Louisiana with the support of the US Government.” 1 ASX Announcements, 5 & 7 May 2025 2 ASX Announcement, 4 September 2024 ASX Announcement 12 November 2025 ASX: ABX TB008 East 530787 Nth 5395777 From (m) To (m) TREO ppm TREO- CeO2 ppm Perm Mags ppm Dy+Tb TREO % Nd2O3 ppm Pr6O11 ppm Tb4O7 ppm Dy2O3 ppm Other REE ppm 0 1 276 165 57 3.2% 39 10 1 8 219 1 2 5,318 3,113 1,218 2.9% 849 213 22 134 4,100 2 3 1,404 1,045 322 4.6% 206 51 8 56 1,082 Permanent Magnet REE ASX announcement 12 November 2025 page 2 Figure 1: Location of T8 Drilling campaign in November 52 km east of the ABx’s REE Resources Figures 2-4: Commencing new drill program along strike from TB008 in EL27/2022 Temple Bar This shallow mineralised layer starts immediately below the thin grey soil Further reports: ABx looks forward to updating shareholders about the progress of its rare earths business, including the quality of the first mixed rare earths carbonate sample to be produced by ANSTO from the Deep Leads bulk sample in the near future, which is eagerly awaited by potential customers.3 This announcement is approved for release by the board of directors.

Competent Persons Statement The information in this report that relate to Exploration Information and Mineral Resources are based on information compiled by Ian Levy who is a member of The Australasian Institute of Mining and Metallurgy and the Australian Institute of Geoscientists. Mr Levy is a qualified geologist and a director of ABx Group Limited. Mr Levy has sufficient experience, which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of exploration Results, Mineral Resources and Ore Reserves. Mr Levy has consented in writing to the inclusion in this report of the Exploration Information in the form and context in which it appears. Table 2 - Summary of resource estimation information of 20 November 2023 referred to above, in accordance with LR 5.8.1 Geology and geological interpretation REE mineralisation occurs in clay layers that overlie a Jurassic age dolerite basement in a district with some residual weathered Tertiary age alkali basalt. Jurassic age tholeiitic dolerite and Tertiary age bauxite-laterite are the main bedrock geological units. Paleochannels host thicker clay zones which host the rare earth element mineralisation. Sampling and sub-sampling techniques Sampling was at 1 metre intervals. Subsampling for assaying is by quartering the clay samples twice and each time, mixing diagonally opposite quarters. Assay results from resampling correspond satisfactorily. Drilling techniques Auger drilling Criteria used for classification, including drill and data spacing and distribution. Not applicable for this report on a test of exploration technology. Sample analytical method Assay samples are analysed by standard NATA-approved induction coupled plasma analytical methods for rare earth elements at ALS labs in Brisbane (method ME-MS81) and LabWest in Perth (method MMA04). Interlab comparisons proved satisfactory. Estimation methodology Not applicable for this report about a scout drilling campaign Cut-off grade Not applicable for this report about a scout drilling campaign Mining and metallurgical methods and parameters, and other modifying factors Not applicable at this initial discovery stage.
