We mine coal using the standard truck-and-shovel open-pit mining method commonly used in Indonesia; however, we are exploring the possibility of other open-mining methods and underground mining, which are not commonly used in Indonesia, in all our current concession areas. Our open-pit mining method consists of eight major steps: (1) exploration; (2) mine planning; (3) overburden removal; (4) coal mining; (5) coal hauling and processing; (6) coal barging; (7) transshipment/Coal Terminal loading and (8) environmental and social activities

The coal production chain that we use is illustrated below:
