Impact Minerals (ASX: IPT) reported progress across its high purity alumina (HPA) strategy and exploration portfolio during the December 2025 quarter, with development work advancing at Lake Hope and downstream commercialisation initiatives gaining momentum. Work under a grant from the Cooperative Research Centres progressed the Lake Hope project, with successful bench-scale membrane crystallisation of potash by-product generated from Stage 1 of Impact’s patented HPA process. Impact continued to assess the integration of Lake Hope with HiPurA assets acquired through its 50% interest in Alluminous, which the company believes could materially accelerate entry into the HPA market. Broken Hill Exploration RestartedImpact announced the resumption of exploration at its 100%-owned Broken Hill project in response to higher metal prices, new internal exploration concepts, and renewed regional interest. Impact ended the quarter with $3.37m in cash on hand to support its continued advancement of priority projects.
