Endeavour is ideally positioned as the major pure West-African multi-operation gold mining company, operating 5 mines in Cote d'Ivoire (Agbaou and Ity), Burkina Faso (Karma), Mali (Tabakoto), and Ghana (Nzema). In 2017, it expects to produce between 600koz and 640koz at an AISC of US$860 to US$905/oz.

The development of the Hounde project is expected to lift Endeavour's group production +900kozpa and decrease its average AISC to circa $800/oz by 2018, while exploration aims to extend all mine lives to +10 years.
