The relevance of the research is based on the need to enhance the efficiency of geophysical work in the search for zones of sulfide mineralization in the Northwestern Balkhash region, Kazakhstan. The aim of the study is to analyze, summarize and interpret geological and geophysical materials in order to identify promising areas. A comprehensive set of geological and geophysical methods has been applied, including high-precision gravity and magnetic surveys as well as electrical exploration. As a result of 2.5D volume modeling, taking into account various prerequisites and signs of mineralization, we have identified geological and geophysical criteria for detecting gold mineralization. It has been found that ore mineralization is associated with two types of deposits: terrigenous deposits of carbonates and terrigenous rock masses of the Famennian stage of the Upper Devonian. Geophysical criteria for distinguishing ore zones have been defined for these areas. It is found that non-ore areas show a widespread increase in all parameters of geophysical fields. The conducted research allows forecasting supplementary gold mineralization zones, facilitating future geological exploration for gold and associated metals.
