On the basis of an actual material by the author have been studied typomorphic features of native gold in Dagkesaman gold-polymetallic deposit. At mineralogical study of ores of the given deposit it is established, that gold is in accretion with chalcopyrite and sphalerite, and also in cracks galena, faded ore and quartz. This shows, that according to sulphidic minerals, gold in all cases has subordinated character, i.e. it was allocated after all sulphidic minerals. Forms of allocation of native gold are various (lamellar, angular, thread, isometric).
After etching in Сr2O3 . HCl under a microscope monogranular, unclear zonal and self seldom spotty internal structures were observed in gold grain. All our data of typomorphic features of native gold let to conclude that auric ores of the Dagkesaman deposit were generated in two stages of a mineralization in conditions of small depths.
