Critical Minerals Group signed a technology license agreement with Lava Blue, enabling detailed investigation and development of high purity alumina and other value-adding co-products at the Lindfield Project in Queensland.

The project's JORC resource estimate includes the aluminium oxide required for HPA production.

Recent successful beneficiation test work utilising Lava Blue technology produced 3N and 4N grade HPA.

The collaboration allows the mining company to optimise the HPA production stream and explore other value-adding co-products.
