 Recent exploration of the Borov Dol copper porphyry deposit has made a significant contribution to understanding the geological composition of the deposit and determining the ore bodies. Significant geological explorations have been carried out in the area of the Borov Dol ore deposit, and during 2019, open pit exploitation has started. Along with extensive geochemical and geophysical investigations, a drilling program has been implemented at the site and provided decent exploration results. For this 3D model, all 100 drill holes made in the period from 1966 to 2013 were used. The drill holes have a total length of 23 435 m. Four professional software packages were used in the preparation and production of 3D models at the Borov Dol site. Surfer models of surface halos of copper, gold, lead and zinc ores have been developed, which jointly define the space of the possible feeding channel for copper mineralization and associated metals. The most detailed 3D model of the Borov Dol ore deposit was completed with the professional software package MOVE, which provides the surface visualizations and variants of the 3D model to the depth. Comparison was done with the MineSight software package, which also included compatibility of the geochemical data. Confirmation of 3D modeling was obtained using the professional Vulcan software package, which gave a morphological shape of the complete ore body in 3D visualization and a view of the ore body down to a level of 300 m.
