Origin of Material: AMIS0358 was made using Copper-Cobalt oxide ore from the Mashitu
project, owned by the Camrose Resources joint venture and operated by Eurasian Natural
Resources Corporation (Africa) (ENRC). The Mashitu project is in the Kolwezi District of Katanga Province in the Democratic Republic of the Congo, 204km North west of Lubumbashi and 48km East of Kolwezi. It is hosted by sedimentary rocks of the Neo-proterozoic Katangan sequence developed within the Lufilian Arc in the Central African Copperbelt. Mineralisation is generally hosted within dolomitic shales and argillites of the Lower Mines Series.
Mineral and Chemical Composition: The main economic mineralogy comprises chalcocite, and malachite with subordinate carrollite, chalcopyrite, bornite and heterogenite.
