The state-owned Kumtor Gold Company, Kyrgyzstan’s largest gold mining asset, has announced the high efficiency of its new underground mining operations. According to the company, up to 5 grams of gold can be extracted from each ton of ore mined using the underground method. Experts believe this yield is sufficient to ensure the long-term viability of the deposit.
Although underground mining was officially launched in August 2025, actual excavation began in February. In a response to The Times of Central Asia, the company reported that geological reserves in the underground zones of Kumtor are estimated at 147 tons of gold, enabling the mine to remain operational for at least another 17 years.
“Two tunnels are currently being developed. Poor ore is being mined at the moment, and the system is reaching its design capacity. Full-scale production will be achieved in the coming years,” the company stated.
To date, over 1.5 kilometers of underground tunnels have been excavated at Kumtor. Operations continue around the clock, with special equipment transporting ore out of the mine every ten minutes. To maintain a safe working environment in the high-altitude, cold conditions, warm air is pumped into the tunnels to ensure worker comfort and safety.
Kumtor was nationalized in 2022 after nearly 30 years of operation by the Canadian company Centerra Gold. The previous operator had planned to complete mining operations in 2024 and begin land reclamation. While underground mining was explored in 2015, it was deemed unprofitable at the time, in part due to low global gold prices.
Today, gold is trading at approximately $4,280 per ounce, around $1,000 more than five years ago. This price increase has significantly improved the profitability of underground extraction, making the project economically viable.
