Snapshot	Minim Martap is a tier-one bauxite asset, ranking among the world’s highest-grade deposits. The Minim-Martap Bauxite Project involves Extraction of DSO Grade Bauxite from the Minim Martap Deposit, transportation of Bauxite through haul road from the mine stockyard to the Inland Railway Facility (IRF) in Makor for bauxite evacuation, and the establishment of a port terminal at the Autonomous Port of Douala (PAD) for bauxite export. Project construction commenced in July 2025. Canyon has commenced early works for the Project, including the construction of the Inland Rail Facility (IRF), the upgrade of the haul road and the procurement of long lead items such as locomotives for rail haul. Mining, ore haulage and road upgrade contracts placed, and mining equipment scheduled to arrive on site Q1, 2026.

Deposit type

• Bauxite

Summary:

The project area is located within the Central Cameroon Shear Zone (CCSZ), which is a major northeast–southwest trending structural feature that separates the North-West Cameroon Domain to the north from the Adamawa Domain to the south.

The bauxites were formed from the lateralization of the Cambrian granites. Subsequent erosion has resulted in the current landform of flat-topped plateaus separated by deeply incised valleys, with the bauxites occurring within remnant laterites on the plateau tops. The plateaus are very irregular in shape and, especially those in Minim Martap, are significantly elongated subparallel to the structural trend of the CCSZ. The plateau tops are generally quite flat, but the flanks are usually relatively steep.

The laterite profile typically comprises a thin soil covering, an iron-rich capping, a leached horizon where the removal of silica and iron has resulted in the residual enrichment of bauxite minerals, and a kaolinitic basal clay horizon. Most of the bauxite Mineral Resource is contained within the leached horizon, which is typically several meters thick.

The dominant mineral in the bauxite horizon is gibbsite, with an average concentration of approximately 75%. The other major minerals in order of abundance include goethite, and hematite, with lesser amounts of anatase, kaolinite, quartz, rutile. Boehmite and organic carbon concentrations are very low.

• The mineralisation in the project area is described as plateau-style lateritic bauxite. The deposits have formed from the intense weathering of Cambrian granites and the surrounding Proterozoic meta-sediments, as well as some Tertiary basalts;

• Bauxite development is understood to have commenced during the Miocene Epoch. The intense weathering of feldspathic minerals resulted in the removal of silica, the remobilisation of iron, and the formation and residual concentration of the bauxite minerals (mainly gibbsite);

• The current landform is characterised by broad plateaux separated by deeply incised valley. The bauxite is largely confined to the plateau tops, and the profile typically comprises a thin soil/ clay cover, an iron rich duricrust, a gibbsitic horizon and the underlying basal clays.

Mining Methods

- subscription is required.

Comminution

Crushers and Mills

Processing

Summary:

The bauxite recovered from the surface mining process does not require any additional processing. The surface miner crushes the ore to the required size as a part of the mining process and this ore is then exported as DSO.
