ASX-listed Australian Pacific Coal on Tuesday expressed its disappointment in the Independent Planning Commission’s (IPC’s) decision not to extend the mine life of the Dartbrook coal mine, saying it would "carefully review and consider" the reasons for the decision, and evaluate its available options. The IPC at the end of last week gave the green light for Australian Pacific Coal to restart underground operations at Dartbrook, in New South Wales, using bord and pillar mining.
