The tenement is 18 km2 and is located between the existing Rubble Mound and Wind Break deposits, which form part of the Company’s resource estimate of 89 million tonnes1 averaging 844 ppm total rare earth oxides (TREO). The resource contains 31 ppm dysprosium (Dy) and 5.2 ppm terbium (Tb), and the proportion of Dy+Tb (4.3% of TREO) is the highest of any ionic clay deposit in Australia and among the highest globally.2 The resource has been demonstrated to host ionic rare earths, which can be extracted using a salt solution at ambient temperatures and pressures in less than 30 minutes. In securing the tenement, ABx excluded areas that it considered not prospective for rare earths, and areas of high-value agricultural land. This is in accordance with ABx policy to strive to leave land and environment better than we find it, and to only operate where welcomed. ABx has recently worked with the Australian Nuclear Science and Technology Organisation (ANSTO) to produce the Company’s first mixed rare earth carbonate (MREC) product from a bulk sample extracted from Deep Leads.3 The ABx MREC contains 4.0% dysprosium (Dy) and 0.7% terbium (Tb) as a percentage of total rare earth oxides (TREO), more than twice that of any other peer MREC. Using recent rare earth oxide prices, the ABx MREC basket price is up to 51% higher than peer MRECs, due to the higher proportion of Dy, Tb, yttrium (Y) and other valuable heavy rare earths. ABx is discussing these results with prospective customers. 1 41 Mt inferred, 42 Mt indicated and 6 Mt measured 2 ASX Announcement, 2 May 2024 3 ASX Announcement, 2 December 2025 ASX Announcement 12 December 2025 ASX: ABX ASX announcement 12 December 2025 page 2 ABx Group Managing Director and CEO Mark Cooksey said: “We’re very pleased to increase our highly prospective tenure in northern Tasmania, which provides ABx with further potential to expand our globally significant ionic rare earth project. “The production of our first MREC, which was produced from a bulk sample extracted from Deep Leads, highlights that our ore contains very high levels of valuable heavy rare earths with low impurities, and that high extractions can be achieved at ambient temperatures and pressures in a short time. “This combination of qualities are exceptionally valuable and unusual, and with the addition of this licence we will continue to expand our activities across the region.” Figure 1: Location of EL25/2022 in northern Tasmania Exploration Update ABx Group has recently completed an exploration campaign to expand the high grade T8 Rare Earths discovery, located across the Company’s eastern tenements (EL27/2022 and EL28/2022).4 Assays from this campaign are pending with results anticipated before year-end. 4 ASX Announcement, 12 November 2025 ASX announcement 12 December 2025 page 3 This announcement is approved for release by the board of ABx Group Limited.
