Slide 11: Mineralization
9.0 Mineralization The main economic minerals present at Tenke and Fungurume are malachite, chrysocolla, bornate, and hetrogenite with minor amounts of pseudomalachite, libethenite, bornite, chalcopyrite, carrollite, plancheite, diginite, covellite and manganese wad. Trace amounts of native copper,
Slide 12: Copper-cobalt mineral associations
The primary copper-cobalt mineral associations are homogeneous in both mineralized zones and any variations are due to the effect of oxidation and supergene enrichment. Consequently the mineral assemblages can be grouped into three main categories dependent upon the degree of alteration – oxide, mix

Slide 18: Delineating limits of mineralized zones
For delineating limits of mineralized zones when interpreting from assays, a 1% equivalent copper cut-off was used. To determine equivalence between copper and cobalt, a factor of ten was used, i.e. 0.1% cobalt was accepted as being equivalent to 1% copper. A total of 41 sections were interpreted ac
