OB18 Luano / Chingola - Zambian Copperbelt (sitios de interés)

The largest rock dump at Luano, OB18, comprises mineralized overburden of the Lower Roan Group sediments which comprise mineralized arkose sandstones, grits and schists. Given the synclinal nature of the ore bodies that were stripped, and the pervasive nature of the copper mineralisation throughout the stratigraphy, there is extensive oxide copper mineralization in the overburden dump. Visual inspection of the rocks comprising the dump confirms the presence of copper oxide minerals including extensive malachite as the dominant copper mineral and chalcocite as the sulphide coppermineral.
