In order to achieve the objective of maximum sustainability when the ML42 mining licence expires in 2020, Namdeb is considering adding the Sendelingsdrif deposit to the current mine plan to extend the life of mine along the Orange River. This will enable Namdeb to fulfil its strategic goal of sustaining carat production from Orange River mines beyond 2012, i.e., the life of the mines (hence 'Life of Mines Extension'). The ore deposit consists of ancient Orange River gravels. The intention is that these are to be treated from the surface of bedrock at selected sites, and for the treatable material to be transported to Daberas for further processing and recovery.
