SnapshotGrande Côte mineral sands operation (GCO) is the world’s largest mining dredge operation. Using this mobile mine, Grande Côte Opérations produces mostly ilmenite and zircon, as well as rutile and leucoxene.

The dry mining unit was commissioned at the end of 2022. The dry sand mining unit feeds the floating concentration unit in parallel with the dredge. This makes it possible to increase production capacity and ore reserves.

Deposit type

  • Mineral sands
  • Sedimentary

Summary:

The extensive Senegal-Mauritanian Basin covers most of Senegal and is composed of Mid-Jurassic to Recent, poorly cemented marine sands, marls, limestones and shales overlain by continental lacustrine and marine sediments.

The GCO project is within the belt of coastal dunes that lie along the current shoreline. The dunes, recent in age, are mobile or semi-fixed, pale yellow in colour and overlie older Late Quaternary white marine sands. The dunes range between 5m and 35m in height and the mineralised zones, which are essentially flat-lying, average around 15m in thickness.

The GCO deposit comprises a linear series of Aeolian sand dunes containing an HM assemblage concentrated by wind action. The Aeolian or mobile dunes overlie a substratum of former beach sands representing a recessive littoral environment. These sands also contain a lesser HM concentration. The natural water table generally occurs close to the interface between the mobile dune and littoral sand together with occasional peaty materials preferentially located at the dune-littoral sand interface.

The deposits include: Mboro, Lompoul, Diogo, Fass Boye, Yodi, Mboro Hotel and Noto. The deposits extend over a length of about 70km. There is potential for additional deposits beyond the limits of present drilling, both to the south–west and north–east for a total strike length drilled of 75km.

Dimensions
The resource extends for 75km north–east and averages 2km wide. The average depth of mineralisation is 15m.
