3D Modeling of some copper deposits in the Republic of Macedonia

This paper aims at presenting the 3D models of respective geological settings, deformation structures and geochemical distributions, in terms of better understanding of the related ore-genetic processes and exploration potential. Since the beginnings of mining industry the challenge of mineral exploration is to approach new exploration targets. In that direction, 3D and 4D modelling are the new exploration tools that can help the mineral explorers to visualise, interpolate and interpret geological data, which are critical timeand money-saving methods. In this study 3D-models had been constructed for several Macedonian CuAu polymetallic deposits Kadiica, Plavica, Kazan Dol and Borov Dol. Our 3D models were built by mapping geochemical variations in the Move software by Midland Valley for Kadiica Cu-porphyry deposit and Borov Dol Cu-Au porphyry deposit (gives the opportunity to the user to create slices of the 3D grid and take a closer look to the spatial variation of an assay) as well as in Target 3D for ArcGIS system for Cu-Au high sulphidation epithermal Plavica deposit and Cu vein type deposit Kazan Dol
