The Kumtor deposit is one of the largest gold deposits in Central Asia. It has been operating since May 1997 and is the concession holder for the Kumtor deposit and is responsible for its entire production cycle. At 13 000 feet, the deposit is the second-highest in the world, behind only after Yanacocha in Peru. The main ore mineral is pyrite. Hematite, native gold, gold-silver compounds, and gold tellurides in small quantities are ubiquitous. Sulfides of copper, zinc, lead, arsenic are very rare. The development at the Kumtor deposit is performed through openpit mining, that is, with the use of standard methods of drilling, blasting, loading and transportation in the open pit.
