The definitive feasibility study (DFS) into ASX-listed Alpha HPA’s high purity alumina (HPA) First project, in Queensland, has found that it could generate free annual cash flows of A$280-million a year from the production of 10 000 t/y HPA.
The project is expected to require a capital investment of A$308-million, and would have a capital intensity of A$30 800/t of HPA with unit costs estimated at A$8 730/t HPA after by-product credits.
