The Kis-Kuel Fe-Cu-Au ± (Ag, Mo, Bi) Deposit, Eastern Yakutia (Russia) — A Link between Iron Oxide Copper-Gold and Intrusion Related Gold Systems
The iron oxide copper-gold (IOCG) deposit class includes a number of loosely related deposits with a pool of common characteristics. The Kis-Kuel intrusion-related IOCG deposit in Eastern Yakutia (Russia) with a wide range of mineral styles has a direct genetic link with a cooling intrusion during i...

The iron oxide copper-gold (IOCG) deposit class includes a number of loosely related deposits with a pool of common characteristics. The Kis-Kuel intrusion-related IOCG deposit in Eastern Yakutia (Russia) with a wide range of mineral styles has a direct genetic link with a cooling intrusion during its formation. The IOCG and the Kis-Kuel have common features for this style—an abundance of iron oxides and a low presence of sulfides. Magmatic contribution to the Kis-Kuel deposit is significant.
