Western Yilgarn Limited (ASX: WYX) ('Western Yilgarn' or 'the Company') is pleased to announce a JORC (2012) Inferred Mineral Resource Estimate of 39.27Mt at 22.7% Available Al2O3 and 12.8% Reactive SiO2 for its New Norcia Bauxite Project situated along the Darling Range Region north of Perth, Western Australia.
The Mineral Resource area is situated in the Central Bindoon region of Western Australia. The tenement is held 100% by Western Yilgarn under Exploration Licence 70/6705, covering over 76.6km2 ,and can be accessed from Perth via the Great Northern Highway or Bindoon-Moora Road approximately 120km north.
The Project is well supported by the Highway with the Millendon Junction Narngulu Railway line located to the west of the Project area.
Western Yilgarn Non-Executive Director Mr Pedro Kastellorizos commented: 'We are extremely pleased with the outcomes of our Bauxite Resource Estimations at the New Norcia Project. The results highlight strong scalability and significant potential to increase tonnage through further exploration. Importantly, the current resources are located within trucking distance of a multi-user railway - an advantage that comes at a time of record alumina and bauxite prices'. 'The New Norcia Bauxite Project, together with our extensive Julimar West Bauxite Project and Cardea 2 and 3 Projects, represent a compelling opportunity to deliver shareholder value, create jobs in local communities, and establish Western Yilgarn as a new, independent, and highly profitable supplier of high-quality bauxite. Our technical team is confident that the bauxite deposits offer substantial upside potential, with room for further resource growth along strike and at depth. Planning is already underway for the next phase of drilling across untested zones within the Company's bauxite portfolio, aimed at expanding the current mineralised footprint.
New Norcia Bauxite Project
The New Norcia Bauxite-Gallium Project is part of the Darling Scarp Bauxite Province of Western Australia which centres on Pinjarra, Waroona and Worsley aluminium production 80km to 150km south of Perth. In the early 2010's the New Norcia Project was systematically explored by Iron Mountain Mining Ltd and Alpha Bauxite Ltd. Based on 187 drillholes, the New Norcia Bauxite Project has returned Historical High-Grade Vacuum & Aircore (ASX Announcement 26 March 2025: WYX Secures Prospective Gallium-Bauxite Project - Clarification) Drilling Results includes
This method is specifically employed to assess the composition of bauxite by determining the concentrations of soluble alumina and reactive silica. Notably, only sample intervals containing >25% Total Al2O3 were selected for bomb digest analysis. The Darling Range is comprised of granite and gneiss of the Yilgarn Craton, with minor areas of metasediment and greenstone lithologies. Archaean granite and gneiss units are affected by the weathering process creating bauxite enrichment in the form of gibbsite. Furthermore, these geological units underlie the laterite which is prospective for subsequent bauxite mineralisation and exploration.
Mineral Resource Estimate
The New Norcia Bauxite Project MRE currently stands at 39.27Mt @ 22.7% Available Alumina (Al2O3) and 12.8% Reactive Silica (SiO2) using >25% Al2O3 cut-off. The current estimation extends down to 7 vertical metres from surface. The MRE has been independently estimated by Odessa Resources Pty Ltd (Perth). The estimate has been produced by using Leapfrog Edge software to produce wireframes of the various mineralised lode systems and block grade estimation using an ordinary kriging interpolation. Top cuts were applied to individual lodes as necessary to limit the effect of high-grade outliers. The reporting is compliant with the 2012 JORC Code and Guidelines. With the addition of the 39.27Mt Inferred Mineral Resource at New Norcia, Western Yilgarn's total JORC (2012) bauxite Mineral Resource Estimate has increased to 244Mt.

Forward Plan and Next Steps
The Project has exceptional growth potential with untested bauxite zones within the western and southern portion of the Exploration Licence area. Regional mapping and interpretation of the Western Australia Geological Survey has delineated laterite and pisolitic gravels in which the bauxite occurs. These areas will be systematically targeted as first pass exploration.
