The relevance of this research is determined by the increasing complexity of geological conditions and the depth of exploration works, as well as the need to optimize exploration costs for solid mineral deposits. Thus, the application of effective geophysical methods for studying geological structures and predicting deposits has become a critical task. The objective of this study is to evaluate the effectiveness of a complex of geophysical methods using the example of the Atasu ore district in Central Kazakhstan, aimed at improving the accuracy of exploration work while reducing drilling costs. The study includes the collection and analysis of prior geological information, addressing the geological and geophysical knowledge of the area, the characteristics of its geological structure, and the petrophysical properties of the rocks. A complex approach was implemented, utilizing gravity, magnetic and electrical exploration using the audio-magnetotelluric sounding (AMTS). Gravimetry and magnetometry were particularly effective in mapping geological structures, identifying faults, and distinguishing rock types based on their composition.[2] AMTS proved successful in identifying ore horizons and host rocks, enabling the construction of a detailed geoelectrical model. The results confirm the high informativeness and accuracy of the selected geophysical methods, facilitating the determination of geological structures and the identification of ore zones. The scientific novelty of this work lies in applying a comprehensive approach to evaluating geophysical methods under the specific conditions of the Atasu region. The practical significance of the research is evident in its potential application for the effective exploration of mineral deposits in Central Kazakhstan.
