Cadoux’s HPA Project Progress: Can It Meet Growing Market Demands?

Government Backing Fuels Cadoux’s HPA Ambitions

Emerging critical minerals producer Cadoux Ltd has taken a decisive step forward in its high purity alumina (HPA) project, securing a $600,000 milestone payment from the Western Australian Government’s Investment Attraction Fund (IAF). This payment represents the second tranche of a $3 million grant awarded to support the development of Cadoux’s small-scale demonstration and production plant (SSP) in Kwinana.

The IAF grant is designed to accelerate innovative projects that diversify Western Australia’s economy and create new jobs. Cadoux’s achievement of the Technology Development – Engineering key performance indicator under the grant’s phased schedule underscores the company’s technical progress and commitment to commercialising its HPA technology.

From Pilot Plant to Commercial Reality

Cadoux’s HPA project is notable for its innovative processing design, which has already demonstrated the ability to produce alumina of 99.999% purity at economically sustainable costs. The SSP, the first of three planned construction stages, will produce up to 1,000 tonnes per annum, enabling Cadoux to supply bulk product and samples to prospective customers for testing and qualification.

This phased approach allows Cadoux to optimise processing and downstream product development while positioning the company to scale up to a full commercial plant with a capacity of 10,000 tonnes per annum. The Kwinana location offers strategic advantages for modular expansion, aligning with the company’s vision of becoming a sustainable, integrated HPA producer.

Strategic Importance Amid Growing Demand

High purity alumina is increasingly critical in high-tech applications, including LEDs, sapphire glass, and notably, electric vehicle batteries and static energy storage. Forecasts predict the HPA market to grow at over 33% annually, driven by its role as a separator material enhancing battery performance and safety.

Cadoux’s project aligns with Australia’s broader critical minerals strategy, aiming to establish sovereign supply chains for essential materials. Alongside its HPA ambitions, Cadoux is advancing rare earths processing through its Minhub project in the Northern Territory, further cementing its role in the electrification supply chain.

Looking Ahead

With government support and demonstrated technical viability, Cadoux is now focused on proving the commercial potential of its HPA technology. The milestone payment not only provides financial momentum but also validates the company’s innovative approach in a competitive and rapidly evolving market.
