Geology and Mineralization

The deposit is a silver-lead-zinc carbonate replacement deposit that is hosted within marble of the Kerdilya Formation. The deposit is localized along the south dipping Stratoni Fault, a major structural feature and important mineralizing corridor in the centre of the Stratoni region. The fault separates the Kerdylia Formation to the north, host to the carbonate replacement deposits, from the Vertiskos Formation to the south, host to the Skouries porphyry gold-copper deposit. Mineralization extends for at least 8km along the fault with the historically mined Madem Lakkos deposit to the east of Mavres Petres, and Piavitsa, the focus of Eldorado Gold’s current exploration activity, to the west.


Exploration at Stratoni is focused on testing the open western and downdip extensions to the deposit.
