From the 11th till the 15th century the ores were exploited even by the monasteries of Agion Oros. In the 15th century, the Ottomanans` state organized the exploitation of the ores, so the village was economically developed. In the 16th century a mint was inaugurated and there was built of Fort. In the 18th century, the Turks gave the exploitation of the ores to a group of villages, Mantemochoria, which were obliged to give to the sultan a concrete quantity of silver each year. The general supervision had taken over Madem Pasha, who served the sultan, who was living in the Fort of Stagira. In the end of the 19th century the exploitation was taken over by a company.
