Lake Hope
Lake Hope - High Purity Alumina (HPA) Project
WESTERN AUSTRALIA | IPT 80%
HPA development project acquired to produce 99.99% 4n HPA, a technology sector material and on Australia’s critical mineral list.
Geology And Mineralisation
- High grade aluminous clays in salt lakes.
- 1.5-2 m thick, mineralised at surface, no overburden.
- Exceptional material characteristics for mineral processing.
- Heritage clearance obtained.
High Purity Aluminia
- High Purity Alumina is aluminium oxide (Al2O3) with a purity exceeding 99.99% and superior brightness, hardness and resistance.
- HPA is a technology sector material used in LED’s, Lithium battery separators, catalysts, and synthetic semiconductors.
- 4N HPA commands prices of US$15,000 to US$25,000 per tonne.
- Industry research expects significant demand growth.
Mineral Resources
- 350+ drill holes used to define maiden mineral resource.
- Lake Hope contains JORC 2012 compliant resource of 880,000t Al2O3 at 25.1% Al2O3*.
- Multi-decade source of HPA, with heritage and POW clearance.
- Significant exploration upside across 238 km2 of tenements.
Metallurgy
- Novel hydrometallurgical process has produced 4N HPA from lake clays.
- Meets chemical purity benchmarks of typical HPA.
- Unique material with competitive advantage over kaolin.
Development Pathway - Preliminary Feasibility Study Underway
- Novel hydrometallurgical process has produced 4N HPA from lake clays.
