• Thicker, higher Al2O3 and lower SiO2 bauxite discovered outside of existing Wuudagu resource areas
• Assay results from 96 holes indicate consistently high-grade bauxite profiles
• No historical drilling at Wuudagu E and F, with entire plateau areas outside existing resource estimate

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 96 exploration drill holes on the Wuudagu E and F plateaus, indicating 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. The Wuudagu E plateau covers an area of 0.7 km2, while the Wuudagu F plateau covers 1.9 km2, both located within VBX's exploration and mining tenements. Significant intercepts include 5m at 47.5% Al2O3 and 6.7% SiO2 from surface in WE019, and 6m at 50.7% Al2O3 and 6.9% SiO2 from surface in WF036. Importantly, there has been no historical drilling at Wuudagu E and F, and the entire plateau areas are 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 completed in the second half of 2025, with updated resource estimates for the Wuudagu B, C, CN and CNN deposits expected in the coming weeks, and initial resource estimates for the Wuudagu D, E and F plateaus to follow shortly after.
