Wuudagu Project Advances Amid Environmental Advisory and Resource Expansion

New Bauxite Discoveries at East Kalumburu A

VBX Limited has announced a significant update on its Wuudagu bauxite project in northern Western Australia, revealing the discovery of low-silica, ferruginous bauxite mineralisation at the East Kalumburu A plateau. Assay results from 32 exploration holes confirm encouraging grades, with aluminium oxide content ranging from 32% to 39% and silica levels consistently low, around 4% to 7%. This new deposit lies within close proximity to the existing Wuudagu resource, offering attractive blending opportunities that could extend the mine life beyond the current 10-year plan.

Strategic Appointments Bolster Project Development

In a move to accelerate project advancement, VBX has appointed Ausenco Services Pty Ltd as the Definitive Feasibility Study (DFS) Manager. Ausenco brings global engineering expertise in bauxite and alumina industries, focusing on optimising beneficiation processes and logistics to enhance mass recovery and reduce operating costs. The DFS is targeted for completion in the first quarter of 2026. Additionally, Dr Paul Vogel AM, a respected environmental regulation specialist with extensive experience in mining approvals, has been engaged as a Strategic Advisor to guide the environmental assessment and stakeholder engagement processes, underscoring VBX’s commitment to responsible development.

Extensive Drilling and Sampling Programs Underway

VBX’s exploration efforts are robust, with over 436 drill holes completed across various Wuudagu deposits and East Kalumburu A. This includes 65 holes at Wuudagu D, 257 holes at Wuudagu B, and additional infill and hydrogeological drilling designed to increase resource confidence and support mine planning. Bulk sampling programs are also in progress to facilitate metallurgical test work, critical for refining processing techniques. The company expects to complete these field activities by October, feeding into an updated resource estimate and optimised mine plan for the DFS.

Project Outlook and Market Context

Wuudagu’s flat orebody with a low strip ratio, combined with its strategic location 30km from the coast, positions VBX well to meet growing global aluminium demand driven by decarbonisation and technological innovation. The project currently holds a 59 million tonne Probable Ore Reserve, with significant upside potential as 52% of target areas remain undrilled. VBX’s focus on low-silica bauxite aligns with market preferences for higher quality feedstock, potentially enhancing its competitive advantage.

Commitment to Responsible Development

VBX emphasizes a socially and environmentally responsible approach, working closely with Traditional Owners and local communities on Balanggarra country. The appointment of Dr Vogel and the transparent management of potential conflicts of interest, such as the dual chairmanship of George Lloyd at VBX and Ausenco, reflect the company’s governance standards. As the DFS progresses, VBX aims to balance commercial objectives with sustainable practices and stakeholder benefits.
