Abstract
The composition, structure, and conditions of formation of the tentatively rich Fedorovskoe-1 primary gold deposit are considered. The deposit was discovered at the site where a gold placer had been exploited for 165 years in a gold-rich Siberian province. It was revealed and investigated using complex geologo-mineralogical, geophysical, and geochemical methods. We have first studied the mineral composition of ores and the structure of the ore field and determined the deposit formation parameters. Based on the results obtained and the earlier established regularities of the composition of gold-ore mineralization and its distribution in the regional ophiolites, new primary gold deposits are predicted in the South Siberian province.
