The Lugokan ore cluster is located in the southeastern part of Transbaikalia within the Aga–Borzya structural–formational zone of the Mongol–Okhotsk orogenic belt. The 40Ar/39Ar dating of K-bearing minerals of syngenetic to ore parageneses has been carried out applying stepwise heating technique: it has been demonstrated that the earliest gold-ore mineral associations are Au–pyrite–arsenopyrite (163 ±1.9 Ma) and Au–chalcopyrite (160 ±2 Ma). The later parageneses encompass the Au–polymetallic (156.3 ± 1.8 Ma) and Au–Bi (155.9 ± 4.5 Ma) one. By their ages and position in the general scheme of the Late Jurassic magmatism of Eastern Transbaikalia, the Lugokan’s ore cluster gold-bearing mineral associations corresponds to the time of intrusion of the Shakhtama pluton (161 Ma) and the Porphyry Complex (159–155 Ma).
