Snapshot	Cabinda is a world-class phosphate project that will produce Beneficiated Phosphate Rock. It consist of the Cácata phosphate deposit and the Subantando (Cabinda) Fertilizer Plant (between Cácata mine and Cabinda City). Construction Update (June 2025): Civil works advanced at the Subantando site, with 80% of earthworks, foundations, and drainage systems completed. Ongoing rehabilitation of haul roads. Accelerated Production Strategy (Nov 2025): • Export and domestic opportunities have been identified for unprocessed phosphate rock; • Stockpile dewatering technology from Moisture Reduction Systems will be used to accommodate early start product; • Minbos not having to install and commission crushing, drying and dust extraction at the Subantando factory, from the outset. • Existing screening equipment and civil installations at Subantando can be used to screen and store the product. All the activities for accelerated start can be utilised for the full development strategy.

Deposit type

• Sedimentary

Summary:

The Phosphate deposits of Cabinda are of the Florida/Morocco sedimentary type and structurally simple, located in structures formed as part of the Atlantic rifting. The area is comprised of a series of broad, gentle folds and grabens trending southeast-northwest, sub parallel to the coast with the phosphate deposits preserved within the grabens. The folds and grabens are cut by steep transverse faults and shear zones perpendicular to main faults in places. Sedimentary cycles can be correlated between grabens based on rock chemistry and sediment characteristics in the phosphatic units.

The deposits are Maastrichtian or Eocene age and locally referred to as the Upper Phosphate Member (UPM), Pebbly Foraminiferal Clay and Limestone Unit (PFCL) and the Lower Phosphate Member (LPM).

Mineralisation at Cácata varies within the sedimentary layers from very high-grade gravels with coprolites, pellets, teeth, and bones to silty fine grained phosphorite low grade zones and is preserved in a narrow graben approximately 400m wide and 4.5km long. The phosphorite beds consist of three (3) main mineral phases, a phosphate phase of mainly apatite/francolite/crandillite, a sand phase of predominantly silica/quartz and a clay phase of primarily iron-potassium rich clay minerals. These phases are clearly seen in the assay results and show grouped distributions of Fe2O3-Al2O3, SiO2 and CaO-P2O5. Except for MgO and K2O, other oxides have very low grades. In the lower grade layers the distributions are more complex and dolomite is a major component of most of these sediments. Contaminants such and Cadmium, base metals and uranium are low (where analysed).
