The history of the discovery, development and study of the Kirovskyi gold ore deposit in the Priamur gold-bearing province is considered. The deposit is attributed to the gold-bismuth type of vein deposits of the gold-sulfide-quartz formation. Gold mineralization is genetically related to the formation of the Dzhalinda intrusion of Early Cretaceous granitoids or a series of later dikes of «variegated» composition. The isotopic age of gold mineralization, determined by the Rb-Sr method, is in the fork 131-126 Ma. Further prospects of the deposit are associated with the search for large-volume deposits with stockwork type ore bodies.
