Project location

The project site is located 1500 – 2500 meters above sea level in territory of Durvuljin soum, Zavkhan province. It’s approximately 1,200 km from Ulaanbaatar city, 150 km from Uliastai city, and 20 km from the center of soum in the western outskirts of Khangai Mountains. The project area has a harsh climate with very low precipitation all year around. In summer, the temperature reaches up to +40°C and in winter it goes down to -40°C. In a semi-desert area of the project, dust storms are regular during summer and snowstorms during winter time.

Operations

Bayan Airag mine uses open-pit mining techniques. Open-pit is a surface mining technique where gold is extracted by cutting the pit open, crushing, heaping, and leaching ore. In the first phase, ore and surrounding waste rocks are removed from an open-pit. Then ore is hauled for less than 1km to a stockpile area. Lastly, the stockpiled ore is then crushed, leached and processed.
