AMIS0246 Cu 1.75%, Co 1973 ppm, oxide, Kinsevere, DRC

Origin of Material: AMIS0246 is a commissioned CRM made from material supplied by SGS Minerals Services from the Kinsevere Copper Mine, 27 km north on Lubumbashi, in the Katanga Province of the Democratic Republic of Congo (DRC). Kinsevere, formerly owned by Anvil Mining Limited, is now 95% owned by Minmetals Resources.

The Kinsevere Project is host to three known copper deposits: Tshifufia, Tshifufiamashi and Kinsevere Hill. Mineralisation extending northwest from Kinsevere Hill is sometimes referred to separately as Kilongo. All of these deposits are hosted by interbedded calcareous siltstones and silty dolomites of the Mines Group sediments. This sequence is overturned and dips steeply eastwards. The main deposit, Tshifufia is an example of a structurally modified, stratiform copper

deposit. Deep weathering extending to approximately 100 m below surface has led to the development of a large oxide Mineral Resource hosted by highly altered dolomitic and argillaceous sediments. at Tshifufia comprises chalcopyrite in crosscutting veins and stringers, produced during the Lufilian Orogeny (approximately 550 Ma).

Mineral and Chemical Composition: Oxide ore mineralogy at Tshifufia, Tshifufiamashi and Kinsevere Hill is composed predominantly of malachite and pseudomalachite, with minor chrysocolla and rare intergrown heterogenite. These occur as disseminations and/or in veins and veinlets, which sometimes coalesce into prominent "clots". Underlying sulphide mineralisation comprises chalcopyrite, chalcocite, and bornite; typically occuring as finely disseminated, bedding parallel layers, stratiform veins or as replacement of pyrite nodules. Lesser cross cutting quartz-carbonate- sulphide veins are also observed. Sulphide remobilisation during faulting has also led to the development of variably mineralised breccias.
