Summary:

Geologically there is a dome structure (the Pinang dome) in the centre of the property. Overburden is mainly sandstone, siltstone and mudstone. Early mining focused on the edges of the dome and virtually all coal seams dip away from this region.

A total of 13 seams range in thickness from 1 to 15 m; typically in the range of 2.4 to 6.5 m. Seam dips vary from 3º to 20º at the outcrop. The coal occurs in the Balikpapan and Pulubalang Formations and the three main coal seams are called Kedapat, Pinang, and Sangatta. The coal is generally lowash and low-sulfur and has low in-situ moisture content. In some parts, the coal rank has been increased, by igneous intrusion, to a high volatile bituminous coal.
