Mayskoye, a high-grade refractory gold deposit, is one of the top five deposits in Russia in terms of gold resources. It comprises an underground mine operating since 2010 and a 850 ktpa on-site flotation concentrator started up in 2013.

Primarily the refractory ore is processed by conventional flotation on site, the concentrate produced is then shipped to third-party off-takers or to Amursk POX plant where gold dore bars are produced using pressure oxidation and cyanidation technologies.


Chaun district of the Chukotka Autonomous Territory in north-eastern Russia.

The deposit is accessible all year round via 187 km of improved unpaved road from the town of Pevek which is a major seaport operating from July to early November.

* GE = gold equivalent. Ore Reserves and Mineral Resources are in accordance with the JORC Code (2012). Mineral resources are calculated in addition to ore reserves
