SnapshotMahakam Sumber Jaya (MSJ) produces high-quality termal coal, having a calorific value of between 5,400 and 6,400 kcal, that is primarily used for raising steam in power plants for electricity generation, as well as in the process of manufacturing cement.

Mining activities are carried out by implementing open pit mining methods, which include the process of stripping layers of soil and overburden to access mineral reserves.

MSJ operation is supported by the relatively close proximity of the mine area and the processing facility with the approximate distance of 45 km. Coal barge loading through MSJ's port in Separi can also be accessed via a special hauling road managed by MSJ.
