Currently, porphyry copper deposits are the main source of non-ferrous metals, and they are distributed on a global scale. Kazakhstan occupies one of the leading places in the world in terms of reserves and production of copper ores. Ore minerals are mainly represented by copper and molybdenum sulfides. Mineralogical studies of copper-molybdenum deposit ores are important for replenishing their resources. The main method for identifying new porphyry copper deposits is the prediction of promising areas associated with the Paleozoic structures of Kazakhstan. The prediction of such promising areas is based on a new geological model created using the principles of geotectonics and geodynamics of Paleozoic structures based on the plume-tectonic position. The characteristics of the selected promising areas are based on the data from field geological studies and sampling of ores and ore-bearing rocks for laboratory research. According to the analysis of the geological material of the geodynamic model of the Paleozoic structures and the geological structure scheme, we have identified promising areas for deposits of priority metals. Field geological and geophysical studies made it possible to identify anomalies, the nature of which is associated with porphyry copper deposits, by analogy with those available in the neighboring ore region. Drilling mapping and exploration wells made it possible to identify new copper-molybdenum ore occurrences. The prospects of the identified new area have been confirmed by field geological-geophysical and laboratory-mineralogical studies. An analysis of the geological structure of ore occurrences in the new area shows that a blind intrusion of Paleozoic granitoids lies at depth, overlain by loose Cenozoic formations. The host rocks of the intrusion have undergone hydrothermal alteration and sulfide mineralization. It can be assumed that endogenous ore occurrences of priority metals, which are associated with blind intrusion, can be expected on the territory of the promising area.
