Zambia Economic Brief, June 2016, Issue 7

“…Nevertheless, there are good reasons for optimism about the potential for additional investment to unlock new increases in Zambia's copper production. A recent United States Geological Survey study of undiscovered copper resources in the region shows a significant quantity of undiscovered copper in Zambia (Zientek et al 2014). The study estimates that 8,400,000 tonnes of undiscovered copper lie in the Roan arenite tract, which extends through the Copperbelt and Central provinces.…”

“…The U.S. Geological Survey (USGS) recently assessed undiscovered resources in sedimenthosted stratabound copper deposits in the Roan Group in the Katanga Basin, Democratic Republic of the Congo and Zambia (Zientek et al 2014). The part in Zambia is named the Zambian Copperbelt.…”

Mineralogical variations with the mining depth in the Congo Copperbelt: technical and environmental challenges in the hydrometallurgical processing of copper and cobalt ores

“…The Kimpe ore deposit is located in the southwestern part of the Haut-Katanga region in geological settings that are rich in the mixed copper ores [25,55]. This deposit together with those of Kinsenda and Lubembe, currently mined by the Kinsenda Copper Company, belong to the transition zone separating the Congolese and the Zambian facies [25,55]. The copper mineralization goes in with the mining depth with a slope varying between 65 and 70 .…”

Non-cylindrical parasitic folding and strain partitioning during the Pan-African Lufilian orogeny in the Chambishi–Nkana Basin, Central African Copperbelt

“…1). It hosts over 80 deposits with more than 152 million metric tonnes of contained Cu (Zientek et al, 2010) or approximately 200 million metric tonnes according to Hitzman et al (2012), as well as the largest Co reserves in the world ( > 60 %). Metallogenesis in the Central African Copperbelt is generally seen as a multistage and often deposit-specific process with at least some of the following: diagenetic mineralisation pulses are followed by multiple remobilisation stages (including potential new mineralisation) related to basin inversion and compressional deformation, and by later supergene enrichment (e.g.…”
