Snapshot	The Kuansing Inti Makmur (KIM) concession consists of the following 2 coal Pits: - KIM East Pit; - KIM West Pit. Only KIM East is being mined currently.

Deposit type

• Sedimentary

Summary:

The Kuansing Inti Makmur (KIM) concession area is found on the northern edge of the South Sumatra Basin. The South Sumatra Basin was formed due to back-arc extension which began in the late Palaeocene. This extension resulted in an approximately north-trending graben structure which is filled with an Eocene to mid-Miocene age transgressive sedimentary sequence culminating in the deepwater sediments of the Gumai Shales in the mid-Miocene.

The local geology of the area is comprised of a Miocene aged ignimbrite unit (Tmr) which unconformably overlies the Oligocene aged coal-bearing sediments belonging to the Sinamar Formation (Tos).

The Sinamar Formation is of an equivalent age and sedimentary setting to the Oligocene Talang Akar Formation, seen elsewhere in the basin. The ignimbrite unit varies in thickness between 50 m and 60 m and appears to have been deposited on an erosive paleo-surface which has been incised into the coal-bearing sediments of the Sinamar Formation.

The coal-bearing sediments dip gently (less than 10 degrees) to the north-northeast. The area appears to be structurally relatively benign, with no evidence of significant displacement of the coal seams in the area.

The coal quality in the KIM concession area can be summarised as sub-bituminous coal with moderate total moisture and moderate ash.
