Our lead and zinc mining started in 1964 and continues to grow with new investments. 1.5 million tons of lead, zinc and silver ore were extracted in our Kayseri and Niğde areas until 2006. 70% of the produced ore was sold to Çinkur İşletmeleri A.Ş. and 30% was exported. Oxide production in Kayseri-Aladağ region and sulfur production in Çadırkaya region. In 2008, 90,000 tons of sulfur and oxidized ore will be produced. While the high grade portion of the produced oxidized ore is sold as a minimum of 25% rich zinc ore; low grade fraction and all of the sulfuric ore are enriched and exported from our flotation facilities in Çadırkaya since the end of 2006. In the drilling works carried out in Balikesir / Balya and Gümüşhane / Kırkpavli regions, more than 5 million tons of lead-silver ore has been detected and the studies for increasing the reserves are continuing rapidly.
