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.

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
- Open pit waste stripping of Stage 3 & 4 and Stage 5 continues in 2018, accessing ore for processing in 2019.
- Development of two underground Declines to access first ore from the 395mRL and 380mRL is in progress and is expected in H2 2018. First ore production from long-hole open stopes are planned for H2 2018.
- Processing projects are focused on automation of pH control, automation of cyclone feed and adsorption columns on thickener overflow.
- Regional exploration is focused on the Khaikta area.
