The Golets Vysochaishy gold deposit is located 175 km from Bodaibo. The Vysochaishy Mine includes three processing mills, a fire assay laboratory, an open pit mining site, a placer gold mining site, and a mine camp. The deposit development is carried out with two open pits — the Western and the Eastern.
Balance ores with a gold grade >1.9 g/t are delivered to Mill 2, balance ores with a gold grade ranging from 1.0 to 1.9 g/t — to Mill 3, and off-balance ores — to the off-balance ore stockpile.
The total processing capacity of the Vysochaishy Mine’s mills is c. 4.5m t p.a. Mill 2 applies the gravity and flotation processing scheme with the flotation concentrate cyanidation. Mill 3 consists of gravity processing with further treatment of the gravity concentrate in the Mill 2 cyanidation plant.
The Ykanskoye gold deposit is located 130 km from Bodaibo. The deposit is developed with the open pit mining method. .
Balance ores with a gold grade >1.0 g/t are delivered to Mill 4, off-balance ores — to the off-balance ore stockpile.

Ugakhan is a development project of the Company in the Irkutsk Region. The deposit is located in the Bodaibo Area of the Irkutsk Region, 25 km west of the Golets Vysochaishy deposit. The Mine was launched on October 23, 2017.
The Ugakhan deposit has an extensive mineral resource base, which, together with the shallow bedding of the ore body and favourable physical and chemical properties of the ore, substantially offsets the low average grade (1.07 g/t). In accordance with the updated JORC-compliant statement, the Proved and Probable reserves are estimated at 824k oz of gold and the Measured, Indicated and Inferred resources — at 1,376 koz of gold. In the reference period, since the processing plant start-up date, the mine produced 14.8k oz of gold./p>
In 2019, the Ugakhan Mine produced 75.6 koz of gold owing to a significant growth of the throughput, higher grades and recoveries. Improved performance of the processing plant in the second half of the year was achieved at the expense of stabilization of its operation and application of the crushing complexes./p>
