Nimba (Yekepa) [Nimba] is ArcelorMittal's Liberia operations that include four deposits, Nimba, Mount Tokadeh, Mount Gangra and Mount Yuelliton. The deposits are approximately 111 kilometres north-east of the capital Monrovia ArcelorMittal has been mining DSO at Yekepa since 2011 and rails its product 250 km to the port at Buchanan. Production commenced at Mt Tokadeh but the high grade DSO product from this site is depleting and in Q4 2017 ArcelorMittal started transitioning mining to their nearby Mt Gangra deposit. ArcelorMittal had originally planned to build a concentrator to process the lower grade ore and increase production to 15 Mtpa but this was put on hold in favour of extending the current DSO operation. A feasibility study to identify an optimal concentration solution as been launched with results of the study expected at the end of 2018.
