• Assay results from 65 holes show consistently thicker, higher Al2O3 and lower SiO2 bauxite profile than previous drilling
• No historical drilling at Wuudagu D, outside existing resource estimate of 95.9Mt at 39.4% Al2O3 and 13.4% SiO2
• VBX targeting increase in Wuudagu resource estimate from over 6,000m of exploration and infill drilling in H2 2025

VBX Limited (ASX: VBX) is pleased to provide an update on progress towards development of the Wuudagu bauxite project in northern Western Australia. Assay results have been received from 65 holes of exploration drilling on a 150m by 150m spacing at the Wuudagu D plateau, which is a 1.8km2 bauxitic plateau located within the company's exploration and mining licences. The results indicate the presence of a consistently thicker, higher Al2O3 and lower SiO2 bauxite profile than has been seen in previous drilling at the Wuudagu A, B, C, CN and CNN deposits. Significant intersections include 5m at 48.2% Al2O3 and 7.7% SiO2 from surface, 6m at 46.2% Al2O3 and 4.3% SiO2 from 1m, and 4m at 50.9% Al2O3 and 8.8% SiO2 from surface. There has been no historical drilling at Wuudagu D, and the entire plateau area is outside of the existing Wuudagu Indicated and Inferred Mineral Resource Estimate of 95.9Mt at 39.4% Al2O3 and 13.4% SiO2. VBX is targeting an increase in the size and confidence of the Wuudagu resource estimate from over 6,000m of exploration and infill drilling that has been completed in the second half of 2025. The remaining exploration drilling assay results from the 2025 Wuudagu drilling program are expected to be received in the coming weeks.
