Name of the Project
Cadoux kaolin and Kwinana high-purity alumina (HPA) project.

Location
Western Australia.

Project Owner/s
FYI Resources.

Project Description
The project has a proven and probable reserve of 3.2-million tonnes grading 24.8% aluminium oxide. The ore reserve is based on the eco­nomically mineable portion of the measured and indicated mineral resource, which is estimated at 11.3-million tonnes grading 22.5% aluminium oxide.

The definitive feasibility study (DFS) is modelled on a 25-year mine life from a potentially long-term mine life of more than 50 years.

Eighteen separate mining stages have been planned for the life-of-mine schedule. The average life of each stage is three years, with a total mine life of 51 years. The DFS has noted that the processing of this ore, in the mine plan, continues potentially for another ten years until Year 62.

HPA production is estimated at 5 600 t/y in the first year and thereafter at 8 000 t/y.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has an after-tax net present value, at a 10% discount rate, of $543-million and an internal rate of return of 46%, with a payback of 3.6 years, including ramp-up.

Capital Expenditure
The project is estimated at $198-million, compared with the prefeasibility study estimated cost of $179-million.

Planned Start/End Date
The DFS is targeting production of HPA in the second quarter of 2022 through a beneficiation plant, in Cadoux, and a hydrochloric acid leach and precipitation plant, in Kwinana.

Latest Developments
FYI Resources has completed an HPA production trial at its pilot plant in Western Australia.

The objective of the trial was to produce stipulated end-production specifically tailored to the requirements of targeted potential customers and to incorporate several previously noted process design modifications into the production flowsheet.

Samples of the HPA product from the trial will be submitted for analysis to EAG Laboratories, in the US, for independent, high-accuracy confirmation of HPA grades.
