Kolmar operations are located in the Far Eastern Federal District in the Neryungri Region of the Republic of Sakha (Yakutia).
The company holds coal mining licenses within the ancient geological formation — AldanoChulman Plateau, in which the South Yakutia coal basin is located. The official data published by the Federal Agency for Subsoil Use of the Russian Federation suggest that the region has 25 separate coal deposits with 24-37 coal beds, the average thickness of which ranges from 2 to 6 meters.
The thickness of the beds developed by Kolmar operations varies from 1.8 to 6 meters, the stratification depth is 140–200 meters. An important feature of South Yakutia coals is extremely low methane content, which is beneficial to production safety.
The geographical location of South Yakutia gives a strategic superiority to Kolmar operations. Developed infrastructure in the region, good transport access and proximity to the federal highways, railway lines and sea ports allow optimum logistical schemes to be developed both for the internal market and export trade. The population of the regional center, Neryungri city, amounts to more than 50,000 people. There are two power plants in the region — Chulman Power Plant and Neryungri State District Power Plant. There is an airport in Chulman settlement capable of receiving large-tonnage and jumbo jets. Transport access is via Amur-Yakutskaya Highway. The railway connects Kolmar operations with the Baikal-Amur and Trans-Siberian Mainline. The transport terminal in Muchke Bay allows coal to be shipped by sea to the Asian-Pacific region countries.
