Abstract Detailed field mapping and drill core description was undertaken at the Kvemo Bolnisi prospect located in the Bolnisi ore district, of the Lesser Caucasus, in Southern Georgia. This study facilitated the distinction between the main host rock facies units and understanding of the lithological control to copper-gold mineralization. The base of the oxidation zone controls the distribution of supergene gold and underlying copper mineralization in upper non-welded permeable ignimbrite, while the lower welded fiamme ignimbrite hosts copper ore mostly within the cross cutting the polymictic breccia pipe. The columnar jointed, post-ore dacite body represents the final volcanic event in this area.
