The mining operations are segregated into three mining areas; Bukit, Kintap and Mulia. The mining areas of Bukit and Kintap cover a bituminous coal formation across 35km of strike with the southern area of Mulia in sub-bituminous coal formations.

Satui mine has been operating since the early 1980’s and as a result there are several old open cast mining areas across their large mining lease.

The Satui mine produces bituminous coal with the process includes breaking the coal chunks into smaller pieces, separating them by the desired sizes, no cleansing process because of its already low ash content.

Coal processing at Satui Site is done at Muara Port with production capacity up to 10 million tons/ year. Muara Port is equipped with several facilities such as metal detectors, magnet tramps, automatic cross belt samplers, laboratories, continuous infrared temperature sensing, and dust suppression systems.
