CLS was established in 2009, the company was dedicated to being the mining contractor of PT Arutmin Indonesia (AI) for Senakin, Satui and Mulia which strategically located near Arutmin’s port facility – North Pulau Laut Coal terminal (NPLCT) in the north shore of Pulau Laut. Senakin mine produces bituminous coal. Senakin coal is crushed and, apart from a small portion, washed to lower the ash content and heighten marketability. Satui mine produces bituminous coal that requires crushing but does not require washing due to its low ash content. Mulia mine produce eco-coals mainly used as fuel for domestic and foreign steam-energy power stations. The mines produce sub-bituminous coal with extremely low ash and sulphur contents and therefore are environmentally friendly. We are committed to deliver our best service and the communities surrounding our operations, and place sustainable development as integral to the way we do business.
