Relevance of the research is conditioned by insufficient knowledge of the internal structure of deposit Severnoe which is a part of the Elkon ore region (Republic of Yakutia). Interpretation of the internal structure of ore-localizing texture of the deposit will allow selecting more accurately blocks with rich complex gold-uranium mineralization and forming more targeted system of exploration work, avoiding losses during the development of the deposit. Despite the uniqueness of the objects, geographic and economic conditions, complex ores make uranium mining profitable at sufficiently high price for metal. The investigations will allow locating the areas of complex ores and properly gold ones, and significantly increasing the reserves of useful components that can positively influence the situation, as the current internal demands of the country are not replenished by exploiting native deposits and they are compensated by stores, as well as by importation. As a result of investigations there is a possibility to improve the profitability of deposit development and to make safely the import substitution in uranium industry. This technique can be successfully used at the objects with similar geological and structural conditions of mineralization localization. The aim of the research is to study structural localization conditions of complex gold-uranium mineralization at the deposit Severnoe (Elkon uranium ore region) for identifying the patterns of ore localizing tectonic deformation formation and studying their behavior in space and placing complex gold-uranium ores inside. Methods. The authors have studied and processed field geological data using the core photo-documentation. Micromine and Corel Draw software were used in structural sections construction. Results. The authors determined the internal structure of the ore localizing zone Severnaya, selected the feathering tectonic structures (shear, fault) which formed a complex block-mosaic structure of ore zone and built the deposit structural model.
