Zinc and Lead from the carbonate-hosted deposits of Kabwe, within the prospecting area, containing 40% combined zinc and lead, ranks as one of the high-grade Zn-Pb deposits of probable Mississippi Valley – type in the world. The strata bound mineralization comprises massive, breccia and replacement sulphides within carbonate rocks marking the transition from Lower Roan to Upper Roan
In excess of one billion
tonnes of ore (c.2.7% Cu) have been mined from the mines of the Copperbelt and
conservative estimates suggest that a further two billion tonnes await
exploitation. The copper-cobalt mineralization is stratabound within arenites,
shales and carbonate rocks of the lower-Katanga Mine Series Group. Copper
resources have also been identified in the thrust zones of north-western Zambia
which represent zones of detachment between Basement and Katanga sequences, and
in western and central Zambia where shearing and intrusion emplacement through
the lower Katanga succession have generated a considerable number of lode,
stockwork, breccia and skarn deposits. Other types of deposit include the
disseminated copper mineralization in the granites and aplites of the Mkushi
area and copper-bearing stratiform sulfides in the Lusaka area.
Zambia has a history of gold mining on a relatively small scale, with the twenty larger deposits having produced slightly more than 2t of gold since modern mining began in 1902. The largest past producers are Dunrobin (990kg gold), Sasare (390kg), and Matala (225kg); Dunrobin has recently been re-opened by Reunion Mining and is scheduled to produce 500-600kg gold per annum.
Numerous gold occurrences have been reported to be prevalent within the prospecting area which is currently being-re-evaluated.
Aquamarine and tourmaline are prevalent within the prospecting area and occur in pegmatites that were broadly synchronous with the c.486Ma Sinda batholith.
Substantial occurrence as tabular, probably stratiform exhalative, deposits within Basement and Muva sequences, and as supergene enrichments, either capping low-grade sedimentary accumulations or concentrated within sub-vertical fractures of limited vertical extent.
Substantial resources of iron have been identified, occurring primarily as sedimentary ironstones in the lower-Katanga Mine Series successions of central and western Zambia. Total resources of more than 900Mt with an iron content around 50% have been provisionally estimated, with some individual deposits up to 200Mt in size. Small, high-grade skarn and replacement deposits are associated with Pan-African felsic and mafic intrusions that have penetrated the lower Katanga succession in western Zambia, particularly around the Hook Granite Complex, but such deposits have rarely been fully evaluated.
