Location and History
The Berezitovy gold mine is located in the Amur region of the Russian Federation, approximately 50 km north of Urusha (a town of 5,000 people) and is accessible via an all-season road, most of which is paved. The mine is located just 50 km from the Trans-Siberian railway and 100 km from Skovorodino railway station.
Commercial production began at the Berezitovy mine in 2007. The Berezitovy was acquired by Nordgold in late 2008, as part of the controlling interest in High River Gold. Nordgold currently holds a 100% interest in High River, which in turn holds a 99.91% interest in Berezitovy.
In 2015, Berezitovy had a record year, increasing gold production by 2% YoY to 125.3 koz including approximately 4.5 koz of gold doré produced and unrefined at the end of 2014, which was refined in Q1 2015

The Berezitovy mine is a well-established open pit. The Berezitovy processing plant contains crushing, SAG and ball milling and CIP circuits, a tailings water filter plant and a dry tailings storage facility, a water reservoir and potable water wells located on the Khaikta River, sanitary landfills, a sewage treatment plant, mine water settling ponds. Berezitovy has recently expanded to include a heap leach operation to treat low-grade ore.
Milling and Classification
Cyanide leaching and sorption
- Berezitovy will slightly decrease gold production due to processing lower grade ore (c. 2.0 g/t) as the mine completes mining from the Stage 1 and starts ore production from Stage 3, with mill throughput supported by ore supply from historical stockpiles.
- The mine plans to launch a 4th heap leach pad in H2 2016.
- Feasibility Study for underground mining operations at Berezitovy will be designed and submitted to the authorities.
- Sampling, mapping and a LIDAR survey are planned for the large Khaikta licence north of Berezitovy. An initial drilling programme is also envisioned should the results be encouraging.
