The Çöpler deposit is located about 120 km west of the city of Erzincan in central eastern Turkey, and it consists of a subeconomic porphyry-type Cu-Au mineralization overlain by paragenetically later low-sulfidation epithermal-style Au mineralization. The porphyry-epithermal mineralization is spatially related to middle Eocene intrusive rocks, which have been emplaced into a succession of Permian-Cretaceous metasedimentary and carbonate rocks within an ENE-WSW-trending structural window exposed in the northeastern part of the Tauride-Anatolide orogenic block. The intrusive suite at Çöpler consists of different phases of diorite porphyry which contain phenocrysts of plagioclase and hornblende±biotite, set in a groundmass of quartz and plagioclase. Major and trace element data suggest an I-type calc-alkaline magmatic affinity for the diorite porphyries with strong resemblance to magmatic rocks formed in continental arc settings.
