Announcement PDF ASX Release 18 September 2024 RareX review of Mt Mansbridge Project shows highly promising heavy rare earth potential Engage with this announcement at the RareX investor hub. Highlights • Assessment of RareX portfolio project, Mt Mansbridge, uncovers significant heavy rare earth potential • Mt Mansbridge Project comprises one granted tenement and two applications which are now in the final process of granting following the completion of heritage agreements • RareX completed the Mt Mansbridge tenement package application in 2023 due to similarities to Browns Range Heavy Rare Earths Project and access to the Killi Killi Formation • Outcropping xenotime mineralisation with historical pit samples up to 6% yttrium have been identified at the Sigma prospect on the Project; yttrium is a proxy element to heavy rare earths • Sparse drilling confirmed hydrothermal xenotime mineralisation with 4m at 0.48% TREO including 1m at 1.06% - significant exploration upside due to the sparsity of previous drilling • 2km long untested heavy rare earths soil anomaly on unconformity provides the basis of the upcoming field program which has elevated in priority RareX Limited (ASX: REE – RareX, the Company) is pleased to announce a significant update to the 100% owned Mt Mansbridge tenement package (Mt Mansbridge, the Project) following re-assessment of data and the completion of heritage agreements which have been reached with the Tjurabalan native title holders. Given the significance of the outcomes of the re-assessment, exploration will commence in the coming months. Mt Mansbridge is one of the RareX portfolio projects which are being re-assessed and re-prioritised following detailed data analysis and geological reinterpretation. Cummins Range is the flagship engineering project and Khaleesi is the flagship exploration project within the RareX project portfolio. Recent work has been on assessing and prioritising the portfolio exploration assets which has resulted in Mt Mansbridge being escalated in priority. Red Dragon, another RareX portfolio project, has been de-escalated in priority. Mt Mansbridge Heavy Rare Earths (HRE) Project is located 40km from the Browns Range heavy rare earths deposits 10.8Mt at 0.76% TREO with 88% HRE (Northern Minerals Ltd ASX announcement, 10 October 2022) in the Kimberley region of Northern Australia. A review of Mt Mansbridge has confirmed the presence of hydrothermal xenotime (dysprosium-terbium mineral) mineralisation within a larger HRE soils anomaly proximal to an unconformity, very similar to Browns Range. RareX Managing Director, James Durrant, commented “The geological setting and mineralisation style is uncannily like the Browns Range heavy rare earths deposit. RareX has been presented with a wonderful opportunity to find a high value dysprosium-terbium deposit. We are looking forward to exploring the number one location in Australia for heavy rare earths. The Mt Mansbridge Project is just down the road from our Cummins Range deposit and we look forward to a productive relationship with the Tjurabalan people.” For more information, please contact: Investors: James Durrant, Managing Director Engage and Contribute: Investor Hub RareX Limited ASX:REE ABN: 65 105 578 756 RareX HQ Level 1, 338 Barker Road Subiaco WA 6008 Australia P +61 (0) 8 6383 6593 W ree.investorhub.com/welcome P +61 (0) 8 6383 6593 E info@rarex.com.au ree.investorhub.com/welcome rarex.com.au RareX Limited (ASX:REE) @rarex_asx Figure 1- Regional geology and surrounding TREO occurrences.

Showing all known heavy rare earth occurrences in the area. Northern Minerals have discovered several heavy rare earth deposits in the Browns Range complex, 40km to the north east as shown in Figure 2. The deposits can be classified into hydrothermal quartz-xenotime breccia vein deposits such as Wolverine (6.4Mt at 0.96% TREO, Northen Minerals Ltd ASX announcement 10 October 2022), and unconformity related deposits such as Dazzler (0.21Mt at 2.33% TREO, Northern Minerals Ltd ASX announcement 7 April 2020). At Mt Mansbridge, the Killi Killi Formation has an unconformity contact with the Pargee Sandstone to the north and an unconformity contact with the Marraba Basin to the south. In the middle of the Killi Killi Formation is Mt Mansbridge which is an island of Marraba Basin sitting unconformably on the basement Killi Killi Formation. The classification of the Marraba Basin by GSWA is an area of contention, as surrounding age dates suggest the basin is significantly older than Neoproterozoic and more likely Mesoproterozoic. In 1982, Sigma Resources discovered a clay alteration zone with xenotime quartz veins over 300m of strike, 0.4km south west of Mt Mansbridge. Seven pits were dug along the clay altered zone and returned numerous elevated yttrium results with assay values up to 6% yttrium (Figure 3 and Table 2). Sigma confirmed the mineralized trend corresponds with a broad surface uranium-yttrium anomaly and an aerial electromagnetic (EM) anomaly. The aerial EM anomaly was confirmed by a ground electromagnetic survey. In 2021-22, Red Mountain drilled 6 RC holes along the strike of the outcropping horizon (Figure 3) and the two central holes intersected the heavy rare earths mineralization with 5m at 0.31% REO from 51m in hole MMRC002. Hole MMRC007 was drilled down dip and slightly to the south of hole 2 and intersect a broader mineralised zone of 16m at 0.28% TREO from 77m with a stronger mineralised zone of 4m at 0.48% TREO from 87m including 1m at 1.06%. The heavy rare earth content for this mineralised zone is averaging 63%.

This rotation provides some evidence to explain why three of the drill holes MMRC001, MMRC003 and MMRC008 missed the xenotime horizon. Recent drilling from the partly government funded (Critical Mineral Development Program) drill program on the Wolverine deposit at Browns Range has shown these structurally controlled HRE hydrothermal veins extend to over 500m below surface and can thicken with depth. The HRE hydrothermal veining at Sigma is poorly understood and structural modelling supported by surface structural mapping, soil geochemistry and geophysics will lead to a more informed targeted drilling campaign. Soils geochemistry completed by Quantum in 2011 and Red Mountain in 2021, shown in Figure 4, has confirmed and produced substantial HRE anomalies, and has highlighted two sets of HRE anomalous structures in the Killi Killi basement outcrops. The Sigma prospect structural trend at 310o-320o and a conjugate set at 50o-70o. This hydrothermal systematics is very similar to the Browns Range mineralisation and the most mineralised areas are at the junction of these structures as shown in the below geological model Figure 5. The Sigma HRE prospect has a 700m strong HRE-Y-U geochemical signature, suggesting the HRE mineralisation is open along strike. The geochemistry and radiometric readings indicated that, in addition to the Sigma HRE occurrence, there are at least two other lode structures in the Killi Killi that require follow up. 400m to the north of the Sigma HRE vein, at the base of Mt Mansbridge, is a 2km HRE-Y-U surface geochemical anomaly that traverses the unconformity contact between Mt Mansbridge and the basement Killi Killi Formation. The soils suggest there is anomalism coming from the base of Mt Mansbridge sandstone and from the underlying Killi Killi Formation. This target will be a priority for RareX to establish the origin of the HRE anomalism. The RareX team are looking forward to getting boots on the ground and testing the hydrothermal xenotime veining and unconformity targets.
