Open-Pit Mine
Khan Altai Deposit
Located at an elevation of 2,600 meters above sea level, it is currently the highest-altitude open-pit mine operating in Mongolia.
Mine Introduction
The mining site of Khan Altai Resource LLC is located in Naran bagh of Yesönbulag soum, Govi-Altai Province, approximately 1,000 km from Ulaanbaatar and 100 km from the provincial center. According to an internationally compliant JORC resource report, the deposit contains an estimated 86.73 tonnes of gold.
National company
“Khan Altai Resource” LLC is a national company that actively implements advanced technologies and innovation in the mining sector, applying the principles of sustainable development by ensuring a balance between environmental, social, and economic factors. All of the company’s operations are carried out entirely based on the knowledge, skills, and experience of Mongolian engineers and professionals.
Phase I operation
In the first phase of the project, a processing plant with an annual capacity of 3 million tonnes of oxidized ore was constructed, with construction works, equipment installation, and all required engineering infrastructure implemented as an integrated комплекс.
With the commissioning of this plant, mining operations commenced on a stable basis, enabling efficient ore processing and successfully laying the foundation for the future development of a primary ore processing facility.
Phase II operation
In the second phase of the project, a processing plant will be constructed to treat 5 million tonnes per year of primary ore using flotation, oxidation, and CIL technologies, with environmentally friendly and advanced technologies introduced in stages. As part of this phase, a 6.3-km energy-generating conveyor system and stationary crushing plants are being commissioned.
Once the plant is fully operational, the mine’s overall capacity will increase, ensuring stable and long-term mining and production operations, while creating tangible conditions for a significant improvement in production efficiency and output.
