Indonesia state-owned PT Bukit Asam (Persero) Tbk. is looking to acquire coal mines already in production to increase its total production, The Jakarta Post reported Aug. 9, citing President Arviyan Arifin.

Arifin did not disclose details on the potential acquisitions but said potential purchases should significantly increase its production, which stands at 3.33 billion tonnes per year, and produce medium calorie grade goal.

"We do not want green fields and we want large mine sites that can produce 1 [million] to 2 million [tonnes per annum]," Arviyan was quoted as saying during a public exhibit at the Indonesia Stock Exchange in Jakarta.

According to the report, 65.8% of Bukit Asam's coal production is medium calorie grade coal, which is mainly fed to state-owned electricity company PLN to fuel its power plants.
