## Minestarters Atlas summary

VBX Limited released a corporate presentation detailing the advancement of its Wuudagu Bauxite Project in Western Australia. Key highlights include a 108% increase in the Measured and Indicated Mineral Resource to 131.9 Mt and successful metallurgical test work demonstrating improved beneficiation recoveries up to 72.9% while maintaining a high-quality, low-silica product. The company is progressing towards a Definitive Feasibility Study \(DFS\) completion in Q1 2027, with a clear pathway to first production in 2028.

Reasoning: The company presented a corporate update highlighting a substantial 108% increase in its Measured and Indicated Mineral Resource for the Wuudagu Bauxite Project, alongside successful metallurgical optimization test work showing improved beneficiation recoveries and maintained product quality, positioning the project for future development.

- Positive factor: Significant increase in Measured and Indicated \(M&amp;I\) Mineral Resource by 108% to 131.9 Mt.

- Positive factor: Improved beneficiation mass recoveries achieved in DFS test work, reaching up to 72.9% at a +3.35mm screen size.

- Positive factor: Maintained attractive low silica product grade \(3.2% SiO2 at highest recovery\).

- Positive factor: Strong Preliminary Feasibility Study \(PFS\) results demonstrating a pre-tax IRR of 136% and NPV of A$821M.

- Positive factor: Clear pathway to project approvals in 2027 and first production in 2028.

- Negative factor: Delivery of the Definitive Feasibility Study \(DFS\) has been extended to Q1 2027.

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 66

## Classification and evidence

**JORC Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard.

Why it applies: The resource estimate is explicitly stated as 'JORC \(2012\) Mineral Resource Estimate' on page 21.

Evidence · text

> JORC \(2012\) Mineral Resource Estimate

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: The compliance statement confirms that 'the form and context in which the Competent Person’s findings that are presented have not been materially modified' for both the Mineral Resource and Ore Reserve estimates.

Evidence · text

> The Company confirms that the form and context in which the Competent Person’s findings that are presented have not been materially modified.

**Measured Resource**

Polarity: positive

Definition: Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves.

Why it applies: The resource table on page 21 includes a 'Measured' category with 41.9 Mt at 39.8% Al2O3.

Evidence · table

> Measured

Context: 41.9

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: The resource table on page 21 includes an 'Indicated' category with 90.0 Mt at 40.5% Al2O3.

Evidence · table

> Indicated

Context: 90.0

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: The resource table on page 21 includes an 'Inferred' category with 11.3 Mt at 36.7% Al2O3.

Evidence · table

> Inferred

Context: 11.3

**Tonnage Growth**

Polarity: positive

Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved.

Why it applies: The summary states '108% increase in M&amp;I Resource from 2025 drilling program'.

Evidence · text

> 108% increase in M&amp;I Resource from 2025 drilling program

**Contained Metal Growth**

Polarity: positive

Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.

Why it applies: The summary states '108% increase in M&amp;I Resource from 2025 drilling program', and grades are maintained, implying a proportional increase in contained metal.

Evidence · text

> 108% increase in M&amp;I Resource from 2025 drilling program

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The resource table explicitly states 'Based on a 22.5% SiO2 upper cut-off grade'.

Evidence · text

> Based on a 22.5% SiO2 upper cut-off grade

**Recovery Improving**

Polarity: positive

Definition: Recovery improved versus a like-for-like prior test program on the same domain and route.

Why it applies: Mass recovery improved from 59.5% \(PFS 2025\) to 72.9% \(DFS Test Work\) at +3.35mm screen size.

Evidence · table

> 72.9

Context: 55% Solids / 2.0 Min

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: The metallurgical test work involves 'scrubbing and screening parameters' for beneficiation, which is a mill-based processing route.

Evidence · text

> optimise scrubbing and screening parameters

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 2 distinct composites were tested

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
