The Bučim porphyry copper deposit (41.7° N, 22.3° E) is located country of North Macedonia, about 120 km southeast of the capital Skopje and 15 km west of the town of Radoviš. The deposit itself contains four ore bodies: Vršnik, Čukar, Central ore body and Bunardžik. The main ore mineral is chalcopyrite, which is associated with pyrite, magnetite, hematite and rutile, while the main tailings mineral is quartz. Seven types of fluid inclusions were determined based on their petrological appearance and the presence of phases: vapour, liquid, salt phase and ore mineral. High-temperature (418 - 643 °C) and high-salinity inclusions (30.72 - 59.95 wt. % NaCl equiv.) are believed to be ore-bearing. Fluid inclusions of the Bunardžik ore body are typical for porphyry copper deposits, with the exception of about 10 measurements of inclusions that homogenize at temperatures between 1200°C - 1300°C. The analysis of fluid inclusions in the Bunardžik ore body revealed three types of fluids: Fluid 1 is characterized by high temperature and high saility. The FIAs composed of coexisting two-phase and multiphase inclusions reflect a fluid immiscibility. Determined salt phases are halite and sylvite. Th ranges between 513 and 1292°C. Fluid 2 is represented by multiphase inclusions which, in addition to vapor and liquid phases, may also contain one or more salt crystals (L+V and L+V+S). The salt crystal represents halite, this fluid does not contain an ore-bearing mineral. Th range is 288 - 643°C while salinity range is 15.70 - 59.95 wt. % NaCl equiv.). Fluid 3 is represented by two-phase inclusions (L+V) of moderate salinity. Th ranges between 288 and 525°C while salinity ranges between 15.70 and 47.77 wt. % NaCl equiv.
