Fluid inclusions were studied in quartz from economic ores of the Svoboda area, which is one of the main economic areas of the Malmyzh Au–Cu porphyry deposit. The economic Au–Cu mineralization of the deposit formed mostly from chloride fluid. The main physicochemical parameters of the ore-forming include a temperature of 250–350°C, a salinity of 0.8–48.0 wt % NaCl equiv., and a pressure of 15–62 MPa. The calculations of the pressure of ore-forming fluid indicate the depth of the formation of ore mineralization in a range of 1.5–2.4 km and a 900 m ascent of the ore-hosted block during ore deposition. Our data can be used during prospecting and exploration works at Au–Cu porphyry deposits.
