Impact Minerals has reported significant technical progress regarding high-purity alumina (HPA) production for advanced technology applications. 

Through its associate Alluminous, the company achieved a milestone in a joint development program with Charge CCCV, successfully processing HPA to meet particle-size specifications required for lithium-ion battery separator coatings. The project is advancing toward battery-architecture development and electrochemical testing.

Separately, testing at the Lake Hope Project in Western Australia demonstrated that the company's low-temperature leach process can produce HPA with ultra-low levels of uranium and thorium. These results meet industry standards for "zero-alpha" and "low-alpha" alumina, which are essential for semiconductor packaging and thermal management materials.
