This period of prolonged decline resulted in some metal reserve levels of less than half of the known ore reserves reported at the end of 1980. Reserves in 2010 were 64 of 1980 reserves for copper, 37 for nickel, 46 for molybdenum, 15 for zinc, 4 for lead, and 20 for silver. Gold reserves saw an increase of 178 over that same period.

Oct 20, 2020 The ore in copper porphyry deposits is usually located between the potassic and phyllic alternations. There is a pyrite halo surrounding the ore. Chlorite, calcide, epidote, and adularia are commonly present in the propylitic alteration. Pyrite is commonly found in the phyllic alteration.
KCM has mines at Konkola, Nchanga and Nampundwe. At Konkola, we have the flagship Konkola Deep Mining Project KDMP, which involves expanding the production of copper ore at the Konkola mine by accessing the rich ore body that lies beneath what the current operations have been exploiting.
The Toromocho ore body outcrops on the surface at elevations of 4,600m to 4,800m. The copper ore body extends downwards to a flat bottom 500m to 600m below the surface. The highest grade part of the ore body lies within a 1.0 km by 2.0 km body of brecciated skarn, surrounding a cupola-like 7-million year old feldspar porphyry and ...
