The Pic de Fon and Ouéléba iron deposits comprise the Simandou South project.
The Ouéléba and Pic de Fon supergene-enriched itabirite iron ore deposits are located in the southern part of the Simandou Range in south-eastern Guinea. The Simandou Range is part of the Kénéma-Man Domain of the West African Craton. The deposits are hosted within the Simandou Group with the Itabirite Formation overlying the Phyllites and Schist Formations. The deposits have undergone intense multi-phase deformation and are deeply weathered.
The Simandou Range is the result of multi-phase ductile deformation represented by tight synformal fold keels and sheared antiformal structures. The ridge consists of a formation of itabirites (metamorphosed BIF) and phyllites within the Simandou Group overlying basement gneiss and amphibolite. The itabirites and phyllites have been deeply weathered and identifying stratigraphy is difficult, with the only discernible contact being that between the itabirites and phyllites.
The following domains have been interpreted for the itabirites: laterite, carapace, transitional mineralisation, friable haematite goethite mineralisation, friable enriched itabirite, friable poor itabirite and compact poor itabirite.
Phyllite domains have been interpreted for very weak phyllite, soil strength phyllite, weak phyllite, compact pyritic phyllite, weak quartzite and compact quartzite.
Laterite and carapace are sub-horizontal ........
