| Summary: | The description of the geological structure and composition of Albyn gold ore deposit of Harginskyi ore and placer gold node of Amur province is shown. The ore bodies are shown to be located among the Late Paleozoic weakly metamorphosed formations, to have the shape of tabular deposits and to be consisted mainly of quartz-sericite-albite metasomatic rocks (albitites). The ore minerals are pyrite, arsenopyrite and native gold. Number of sulphides in the ores is less than 2%. Gold is occurred to be both small and dispersed and small and large, its fineness is 880-895 %. The deposit is classified as low-sulfide gold-quartz formations. Spotted paragenetic relation of gold mineralization with dikes and small intrusions of Early Cretaceous age is revealed. The oxidation zone is manifested very weakly. Ore can be processed easily by direct cyanidation. |
