Mineral resources and ore reserves of the Samolazovskoye deposit were audited in accordance with the guidelines of the JORC Code. The Probable reserves were estimated at 5,278 kg of gold; Indicated resources, at 6,826 kg of gold and Inferred, at 110 kg.
The ore thermal treatment facility was put into operations at the Samolazovskoye deposit in 2020. The facility permits to control the longitudinal temperature distribution and carry out thermal pre-treatment of refractory ores in accordance with the specified technological parameters. This allows increasing extraction of gold at cyanidation from 20-30% to 90%. The facility proved to be cost effective compared to other technologies for recovering gold from refractory sulphide ores. In October 2021, this project received the ‘Mining Oscar from Breakthrough Technologies nomination at MINEX Russia 2021.
