The relevance of the discussed issue is caused by the need to detect new gold ore deposits within the Yenisei ridge to replenish mineral resources of gold ore in Russia. The main aim of the study is to explore the features of geological structure and gold ore mineralized zones of ore occurrence Yuzhnoe in order to forecast gold ore bodies, and to substantiate the continuation of geological exploration. The methods used in the study. The exploration is implemented by the express method of prospecting gold ore deposits in difficult mountain-taiga landscapes using a complex of lithogeochemical sampling for secondary dispersion halos, schlich, point and trench sampling; spectrochemical analysis for determining gold content, ICP-MS, atomic-and-absorption, X-ray phase analysis and isotope-geochemical methods were used. The results. The complex of prospecting methods allowed the author to reveal ore-controlling zone of fold-discontinuous deformations and localize within it the ore occurrence Yuzhnoe. The latter is located in the south-eastern part of Sredne-Ishimbinskaya area in the zone of dynamic influence of Ishimbinskiy deep fault system. The gold ore mineralized zones were revealed within the ore occurrence. They are presented by a series of lode gold stockwork subparallel bedding zones with low average gold content. A detection of gold ore bodies is forecasted within the most wide and lengthy zone Centralnaya, where the geological exploration is recommended to be continued. The author hascompared the ore occurrence with model objects and determined a set of common criteria and indicators of the ore occurrence with lode gold-sulfide deposits of the Yenisei ridge - Olimpiadninskoye, Veduginskoye, etc. and with «carlin» type deposits. Conclusions. For the first time in the region the gold ore mineralized zones in carbonate-terrigenous carbonaceous sediments of kartochki and aladyinskaya series of the Middle Riphean were detected. The perspectives of gold-bearing mineralization of the eastern slope of the Yenisei ...
