In 2015, the ore reserves and mineral resources were audited in accordance with the guidelines of the JORC Code. The Probable reserves were estimated at 26.2 tonnes of gold; Indicated resources, at 28.2 tonnes of gold and Inferred, at 8 tonnes.
The gold processing plant at the Ryabinovoye deposit was built in 2 years and commissioned in 2017. The design processing capacity of 1 million tonnes of ore per year was increased to 1.6 million tonnes per year. In 2021, a decision was made to gradually increase the plant's capacity to 1.8 million tonnes of ore per year. In 2021, a semi-dry tailings storage facility was put into operation at the Ryabinovoye deposit. This facility will significantly reduce capital expenditures for the construction and maintenance of the tailing dam, as well as reduce the impact on the environment.
