Queensland protestors fighting the reopening of the Ebenezer mine by Zedemar Holdings are considering an appeal after the Supreme Court dismissed their claims.
The Queensland Times reports the group sought to overturn the decision by former QLD mines minister Stirling Hinchliffe to renew the mine's lease.
The challenge previously claimed Hinchliffe had no right to approve the mine because it hadn't been operating for almost ten years and there had been no community consultation.
Local man Graham Turner lead the battle, and said the community would be "adversely affected" by Ebenezer's reopening.
He also said the mine "could lead to the extinction of the local koala population".
According to QT News Turner said protestors had 28 days to appeal the decision and they were seeking talks with new Minister for natural resources and mines Andrew Cripps.
Zedemar Holdings is currently looking to sell Ebenezer and the nearby Bremer View coal project to OGL Resources, which wants to restart production.
