At present, an urgent task is to increase the country’s mineral resource base. Since almost the entire territory of the Republic of Kazakhstan to one degree or another has been studied, it is advisable to carry out additional study of previously discovered sites and ore occurrences. From the point of view of the geological structure and stages of ore formation, the East Atabay site located in the Karaganda region is interesting for study. A low state of knowledge of copper ore at the East Atabay site is associated with an insufficiently complete set of geological exploration work performed earlier. In addition, copper mineralization is not dip-detected and has very uneven thicknesses of ore undercuts along the profiles. The above factors were the main reasons for a detailed study of the East Atabay site. According to the results of the entire complex of work performed, the site was recognized as economically inefficient for introduction into development and requiring more detailed additional study. Taking into account how much the approach has changed in the economic justification of the prospects of the territories in the Soviet period and today, it is necessary to re-evaluate and recalculate reserves and predicted resources within the East Atabay site. Since the first two stages of prospecting works in this area have already been completed by the predecessors (regional geological study of the subsoil and prospecting), it is necessary to complete the next stage: Prospecting and evaluation works. Based on the data of predecessors and new data obtained, the database on ditches and boreholes has been developed, and a wireframe model has been built for ore zones, bodies and lenses, and criteria for prospecting and evaluation works for copper and polymetallic ores have been identified.
