The Pishtene ore occurrence is situated north-northeast from the Pishtene paleovolcanic center in the western part of the Srednogorie zone. The occurrence is hosted by altered basaltic trachyandesites. The styles of alteration are advance argillic, argillic, sericitic and propylitic. Ore mineralization is in quartz-sericite zone and is represented by quartz-pyrite and quartz-polymetallic. The ore minerals are pyrite, chalcopyrite and sphalerite. Pyrite from quartz-polymetallic stage is with high concentrations of Cu, Se and Co. Au with low contents is also detected.
