Name of the Project
Cabinda phosphate project.

Location
Cabinda province, Angola. 

The Cabinda phosphate fertiliser plant is being developed in the Subantando commercial precinct, about 36 km from Cácata and 16 km from Cabinda port.

Project Owner/s
Minbos Resources, through its subsidiary Phobos and the Angolan project companies Soul Rock Lda and Minbos Resources Lda. 

Project Description
The integrated phosphate mine and fertiliser project comprises the Cácata openpit phosphate mine and the Cabinda phosphate fertiliser plant at Subantando. The plant was originally planned for the Futila Industrial Zone. Minbos subsequently relocated it to Subantando. 

The Cácata deposit has proven and probable ore reserves of 4.72-million tonnes grading 30.1% phosphorous pentoxide. Mining is planned using conventional openpit truck-and-shovel methods.

The 2022 definitive feasibility study (DFS) envisages staged production from an initial 187 500 t/y plant train, with expansion to two trains. Average fertiliser production over the estimated 20-year project life is forecast at about 236 000 t/y.

Minbos is also pursuing an accelerated-start strategy under which uncrushed phosphate rock could be dewatered at the mine, screened and stored at Subantando, and sold before the full beneficiation and granulation circuit is commissioned. Full-scale beneficiation and granulation remain part of the longer-term development strategy.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The October 2022 DFS estimates 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 period of 4.8 years. 

Capital Expenditure
The October 2022 DFS estimated capital expenditure at $48.5-million. This estimate predates the relocation and redesign of the plant and the accelerated-start strategy, which Minbos has said could defer about $20-million of initial capital expenditure. The Phase 2 construction contract, the scope of which covers activities until dry commissioning is valued at $13.8-million.

Planned Start/End Date
Phase 1 civil construction has been completed. Phase 2 construction will advance the plant through structural, mechanical, electrical and instrumentation installation to dry commissioning. 

Latest Developments
On June 22, 2026, Minbos signed a $13.8-million Phase 2 construction contract with Grupo Arliz for all the remaining works required to advance the fertiliser plant to dry commissioning. The scope includes structural steel, mechanical installation, electrical and instrumentation works, and process-control systems.

Grupo Arliz also completed Phase 1 comprising the project platform, roads, drainage, slabs and foundations. The plant and equipment, which were designed by FEECO International and shipped to Angola in 2023, are in Cabinda and ready for assembly.

Minbos received the first $4.8-million drawdown under its $16-million Industrial Development Corporation of South Africa (IDC) facility in June 2026 and ordered long-lead items. 

A $5.48-million Banco de Fomento Angola term sheet was signed in May 2026. 

Minbos has said that the IDC facility and proposed BFA funding are sufficient to complete construction of the fertiliser plant.
