Supergene enrichment of the Kitumba IOCG deposit, Zambia
Iron oxide copper-gold (IOCG) deposits host Cu and Au, as well as numerous other potential
by-products such as U, Ag, Co, and rare earth elements. The Kitumba IOCG deposit in
Zambia has undergone multiple stages of alteration and sulfide formation and subsequent
supergene enrichment, with Cu reaching up to 30% in supergene zones down to depths of
several hundred metres. Quantitative mineralogy characterised five styles of mineralisation.
Stage 1 hypogene chalcopyrite and pyrite, is progressively replaced by Stage 2, a …
