The occurrence of Cu 3 (As,Sb)S 4 minerals, i.e. the enargite and luzonite-famatinite series, is poorly known in Neogene Baia Mare metallogenic district, NW Romania, with few records no analytical data. This study provides first EPMA XRD data on enargite/luzonite from Cisma ore deposit Băiuţ field, Herja deposit. Vein-type bodies bearing minerals are hosted by Paleocene–Eocene flysch successions, while host rock enargite-bearing unknown. series as "exotic" low sulphidation epithermal deposits, "typical" high deposits association tennantite, "sometimes common" small amounts intermediate deposits. district suggests need to update interpretation for several partly at scale relation other deposit/mineralogy features, e.g. vuggy silica, hypogene argillic alteration.
