Impact Minerals yet again as lowest-cost global HPA producer - Lake Hope's PFS released
Impact Minerals has once again confirmed its position as the lowest-cost global HPA producer with its recent release of a Pre‑Feasibility Study (PFS) for its Lake Hope High‑Purity Alumina (HPA) project in Western Australia. According to the PFS, the Net Present Value (NPV₁₀) is no less than AUD 1.165 billion (USD 746 million), a flat‑line CapEx of AUD 259 million (USD 167 million), and operating costs of ~USD 5,860 per tonne. However, it shows a potential of sliding below USD 4500 with the byproduct credits.
Strategy meets scale: Impact Mineral’s vision for HPA growth
Pilot plant & government-backed innovation
A pilot plant is underway with CAD 2.87 million (USD 2.07 million) in UK‑PCRC funding, partnered between CPC Engineering and Edith Cowan University. The plant is focused on membrane research and process optimisation, and the pilot will deliver HPA samples to support offtake negotiations.
