The Gross mining cluster is a highly promising world-class cluster located in the southwest of the Sakha Republic (Yakutia), which includes the operating Nordgold Gross and Tabornoe mines, as well as the Tokko development project. The cluster provides more than 2,000 jobs.
Gross Cluster has a processing plant with crushing and heap leach extraction capabilities. Operations at Gross Cluster utilize the simplest heap leach extraction method available, due to the highly oxidized low-grade ore. Production at Gross Cluster is subject to significant seasonal variations due to harsh winter temperatures. The majority of crushing and stockpiling of ore occurs from May to September, and the majority of gold production occurs from July to December, as the cyanide spray used in heap leaching cannot penetrate frozen ore.
