PT Anugerah Alam Manuhing (AAM) is a PMA company with an ownership structure comprising Cokal 75% and Indonesian owners 25%. A total of eleven coal outcrops were recorded during a geological mapping survey investigation which discovered coal seam thicknesses ranging between 0.42m and 4.20m.

The field descriptions and photographic evidence are supportive of a high rank coal. These higher coal ranks are characterised by very low volatile matter content, very high carbon content and high specific energies. At this stage, AAM is interpreted to consist of thermal and metallurgical coals of export quality.
