How does Elga coal threaten the environment? The Elga coal deposit in the Sakha Republic (Yakutia) is one of the world’s largest reserves of high-grade coking coal . In 2020, the assets of the Elga Coal Complex were sold to A-Property, a company owned by billionaire Albert Avdolyan. Since then, coal production at the Elga deposit has increased fivefold , reaching 36 million tonnes in 2025. Last year, the Pacific Railway was also launched , connecting the deposit to the Port Elga coal terminal.
