The Simandou iron ore project in Guinea contains one of the world’s largest known undeveloped high-grade low-impurity iron ore deposits, demand for which is increasing as steelmakers look to reduce carbon emissions.
The Simandou site is divided into four mining blocks, broken up into two projects: Simandou North (blocks 1 and 2) and Simandou South (blocks 3 and 4). The two northern blocks (blocks 1 and 2) are owned by SMB-Winning Consortium.
Rio Tinto and its Simfer joint venture (JV) partners have determined key agreements with the Republic of Guinea and Winning Consortium Simandou (WCS) on the trans-Guinean infrastructure for the Simandou project. |

The Simandou project operates under the Simfer joint venture where the Government of Guinea holds 15% and Simfer Jersey holds 85%. Simfer Jersey is owned by Chalco Iron Ore Holdings (CIOH) (47%) and Rio Tinto (53%). Rio Tinto and CIOH, own 45.05% and 39.95% of Simandou, respectively.

Summary:
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 ........
Summary:
The proposed mining operation will be open cut mining with a large annual tonnage (after initial production and ramp up). The proposed bench height is 12 m and this has been taken into account for the selection of the resource model block size.
