Andromeda Metals Limited (ASX: ADN) provides an update on its High Purity Alumina (HPA) project, which aims to commercialize the production of high-quality alumina using Great White kaolin as feedstock. The HPA pilot plant has been assembled, with commissioning underway and testwork expected to continue through Q3 2026. This milestone marks the transition toward continuous process production of HPA and the generation of commercial samples for customer qualification in H2 2026. The project builds on the 99.9985% HPA purity achieved at laboratory scale and the strong economics confirmed in the 2025 Scoping Study. Additionally, the pilot plant testwork will generate by-product materials for further analysis, potentially providing additional value streams.
