Cardea 3 Bauxite Project
Overview
Cardea 3 (E70/6727) is located approximately 17.5km east of Julimar West. This project expands Western Yilgarn’s footprint in the high-grade bauxite terrain within the Darling Range Mineral Field of Western Australia.
In July 2025, Western Yilgarn announced its maiden Inferred Mineral Resource Estimate (MRE 2012 JORC) of 3.78Mt at 35.8% Available Al2O3 & 3.7% Reactive SiO2 as part of a larger 16.57Mt at 34.2% Total Al2O3 & 30.2% Total SiO2 (cut-off: ≥25% Al2O3) for its Cardea 3 Bauxite Deposit.
The resource is 3.78Mt at 35.8% Available Al₂O₃ and 3.7% Reactive SiO₂ (cut-off: ≥25% Available Al₂O₃) represents the high-grade portion of the 16.57Mt Global Resource, based on 139 drillholes out of a total of 422 completed to date.
The MRE zone at Cardea 3 extends approximately 3km in length and averages 1km in width, with mineralisation occurring from surface to a depth of 7 vertical metres.
Exploration Potential
Western Yilgarn believes a strong foundation exists for further resource growth at Cardea 3 on the western portion of exploration licence E70/6727, where a 3km strike by 1km wide area remains untested for bauxite mineralisation, in addition to the western portion of exploration licence E70/6702, with a 3.8 km strike by 1.2km also remains untested.
Bauxite from the Darling Range plateau is highly suited to Direct Shipping Ore (DSO) export, owing to their high-grade, gibbsitic composition and low reactive silica content (<5%). Cardea 3 demonstrates significant potential to host an economic bauxite resource of sufficient size and quality to support a small- to medium-scale DSO operation, targeting established alumina refineries in China and the Middle East via seaborne export.
