Name of the Project
Cabinda phosphate project.

Cabinda, Angola.

Project Owner/s
Minbos Resources.

Project Description
A definitive feasibility study has shown the project to have robust economics, with relatively low capital-expenditure requirements.

The project includes the Cácata phosphate deposit and the Futila fertiliser plant.

The phosphate deposit has proven and probable reserves of 4.72-million tonnes at 30.1% phosphorous pentoxide. The mine supporting the ore reserve is based on the openpit mine using a conventional truck-and-shovel mining methodology.

The fertiliser plant will have a capacity of up to 187 500 t/y in a one-plant scenario, expanding to two plants in supporting an estimated 20-year project life. Each train will have a production capacity of about 187 500 t/y.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
In the base case, the project has an after-tax net present value, at a 10% discount rate, of $203.2-million and an internal rate of return of 39%, with a payback of 4.8 years.

Capital Expenditure

Planned Start/End Date
First production is expected in the fourth quarter of 2023.

Latest Developments
Minbos is engaging with its syndicate of investors on the potential yellow phosphorous project development and technical review to develop a new energy material business, with the syndicate confirming the Cabinda phosphate rock will be suitable for yellow phosphorous production.

The study into the potential production of yellow phosphorous is expected to take ten weeks to complete.
