The Bakyrchik gold ore district, located in Eastern Kazakhstan, represents one of the most promising areas for gold reserve expansion. This paper examines the geological structure of the district, with a particular focus on the Kyzylovskiy compression zone as a key element of the ore-bearing structure. Special attention is given to gold deposits hosted within black shale formations, including the type locality—Bakyrchik. The study analyzes the lithogeochemical conditions governing the formation of gold-carbon-sulfide ores, which are associated with Carboniferous-age carbonaceous marine formations that played a crucial role in ore-forming processes. Prospective ore localization zones have been identified, encompassing the Bakyrchik ore field, which hosts both large deposits (Bakyrchik, Bolshevik) and medium to small-scale occurrences (Sholabay, Kholodny Klyuch, Promezhutochnoye, Goluboy Log, Sarbas). The structural characteristics of ore-hosting rocks and their influence on gold concentration are described. The study also explores the role of tectonic deformations, hydrothermal processes, and metamorphism in the redistribution of gold within ore-bearing zones. Specific recommendations for geological exploration aimed at expanding the resource base are provided. Methods of structural-geological and geochemical analysis are suggested for predicting new ore occurrences. The paper also discusses the potential for discovering additional deposits within the studied area and the applicability of these findings to other ore-bearing regions in Kazakhstan. The results of this study hold significant theoretical and practical value for gold deposit forecasting and exploration in black shale complexes, as well as for assessing the potential of analogous structures in other regions. The findings can be utilized to optimize exploration strategies and the development of gold ore deposits.
