The paper presents the S isotopic composition of sulfdes from the Ak-Sug Au-Cu-porphyry deposit hosted by Early Proterozoic magmatic rocks. The S isotopic composition of sulfdes varies from +1.0 to +3.2 ‰: +2.5 to +3.2 ‰ for molybdenite-I, +1.0 to +3.1 ‰ for pyrite-III, –2.3 to – 0.9 ‰ for chalcopyrite-III–V,–2.9 to –2.4 ‰, for chalcopyrite-VI and –1.0 ‰ for pyrite-V. The close-to-zero S isotopic ratios of sulfdes from the Ak-Sug deposit indicate magmatic (from –5 to +5 ‰) or mantle (from –3 to
