A series of prospective ore occurences (Yuzhnoe, Bureminskoe, Magdokokskoe) has been detected for the first time within the eastern underexplored part of the Yenisei Ridge. The paper discusses geological characteristics of the ore occurences, their forecasting and prospecting features are distinguished. The ore occurences are characterized by a number of features (substantially disseminated gold mineralization, conformable and subconformable gold-bearing mineralized zones-deposits, wide low-contrast concentrate and lithochemical halos, low average gold content), allowing to regard them as a group of largetonnage gold-sulphide type deposits. The reference deposit for prospective deposits is distinguished. A comparative analysis of the main prospecting features is carried out.
