The Skouries mine is a high-grade gold-copper porphyry deposit located in the Chalkidiki peninsula in northern Greece.

[1] Skouries is a gold-copper porphyry deposit centred on a small, pencil-porphyry stock that intruded schist and gneiss of the Paleozoic Vertiskos Formation of the Serbo-Macedonian Massif in northeastern Greece.

The porphyry is characterized by at least four intrusive phases that are of monzonite to syenite composition, but contain an intense potassic alteration and related stockwork veining that overprints the original protolith.

The Skouries project is permitted under the same Environmental Impact Study (EIS) as the Olympias and Stratoni assets.

This environmental permit was challenged but was upheld by the Council of State, Greece's highest administrative court, in 2012 citing Eldorado's "investment was particularly advantageous for the national economy".
