Wuudagu B and C Mineral Resource Estimate

• 51% increase in Wuudagu B and C Measured and Indicated Mineral Resource Estimate
• Expected to support a material extension of the Wuudagu Project mine life
• 95.8 Mt Measured and Indicated Mineral Resource Estimate at 39.5% Al2O3 and 13.7% SiO2

VBX Limited (ASX: VBX) announced a 51% increase in the Measured and Indicated Mineral Resource Estimate for the Wuudagu B and C (including CNN) plateaus, from the 2025 infill drilling program. The updated Mineral Resource Estimate is 95.8 Mt at 39.5% Al2O3 and 13.7% SiO2, including 21.0 Mt at 39.4% Al2O3 and 13.3% SiO2 for Wuudagu B and 74.8 Mt at 39.6% Al2O3 and 13.8% SiO2 for Wuudagu C (including CNN). The increase in size and confidence of the Wuudagu resource is expected to support a material extension of the Wuudagu Project mine life as part of the upcoming Definitive Feasibility Study (DFS), based on the 6 Mtpa mining rate outlined in the 2025 Pre-Feasibility Study (PFS). The Mineral Resource Estimate was completed by independent consultant, Rod Brown from SRK, a leading expert in the estimation of Mineral Resources relating to lateritic bauxite deposits. An initial Mineral Resource Estimate for the Wuudagu D, E and F plateaus is expected to be completed in February, which will further inform the potential production profile and mine life at Wuudagu as part of the DFS.
