Impact Minerals (ASX:IPT) is advancing its Lake Hope high purity alumina (HPA) project in Western Australia, positioning itself to meet growing demand for this crucial material in the energy transition. HPA, which is aluminum oxide with at least 99.99% purity, is essential for LED lighting, lithium-ion batteries, and sapphire glass applications used in smartphones and military equipment.

The Lake Hope project stands out for its remarkably simple mining approach. The resource consists of aluminous clay material located in a salt lake bed, requiring only shallow mining to a depth of 1-2 meters. This "dig and deliver" model eliminates the need for crushing or explosives, significantly reducing operational complexity and costs.

The company plans to process the mined material at a facility in Perth, strategically located next to a hydrochloric acid plant. This proximity ensures ready access to key reagents, including hydrochloric acid and potassium hydroxide. Impact's team has developed an innovative processing circuit that addresses one of the main challenges in HPA production – acid consumption. Their solution cuts acid usage in half compared to competing projects, making the process more economical and sustainable.

Preliminary economic assessments show promising results, with an estimated NPV exceeding A$1 billion, capital expenditure of A$250 million, and operating costs around US$4,000 per tonne of HPA. The company is progressing toward key milestones, including completion of a Pre-Feasibility Study in Q2 2025 and the commissioning of a pilot plant by mid-2025. The pilot facility will produce kilogram-scale quantities of HPA for potential customer testing.

Looking ahead, Impact is considering various scale-up options, potentially targeting 10,000 tonnes per annum of HPA production. However, management is contemplating a staged approach, possibly building multiple smaller plants rather than one large facility, to manage technical risk and capital requirements effectively.

The global HPA market, currently estimated at 70,000-80,000 tonnes annually, remains relatively opaque with only a handful of suppliers. Impact Minerals' success will depend on proving its technology, securing offtake agreements, and attracting capital investment. The situation mirrors the lithium market a decade ago, with rising demand but limited transparency in supply and pricing. Companies that can successfully navigate these challenges while maintaining cost discipline and meeting development timelines will be well-positioned to capture the growing market opportunity.
