Abstract: Harşit - Köprübaşı (Tirebolu) volcanic associated ore deposit which situated in the Pontid belt, is a pollymetallic massive sulphide deposition hawing its own characteristics.By the geochemical method regional backgraund, treshold and anomaly values ofCu, In, Pb elements were determined and relation between the existing anomalies and known ore lenses are examined.The resulted moddeling can be used as target definition for the similar but unexplored Pontid type deposits.
