Gümüşhane Silvers
In his work Seyahatname, the famous Traveler Evliya Çelebi says that he visited Gümüşhane in 1646, named after the Turkish word gümüş (silver) and Persian word hane (household). And he says “that there are about 70 silver mines in Gümüşhane City, and these silver mines from seven arms, have satiated veins, and it’s a pure silver ore without lead.”
