The Shumny area is dominated by the disseminated mineralization of pyrite in the dike of trachybasalts, trachyandesites, andesites, dacite, granodiorites, and sandstones. On the SW flank, the dike is basic to medium, acidic on the NE, and has a mixed composition in the center. The host rocks are sandstones and siltstones of the Middle Upper Nyakunyinskaya formation of the Upper Triassic. The apparent thickness of the dike is up to 30 m, and the length is about 4.5 km. sulfidization zone can reach up to several tens of meters. The content of sulfides usually does not exceed 1–3%; in local areas it increases to 10%.
