Trans-Tasman Resources will head to court to appeal the Environmental Protection Authority's decision to decline its consent to mine iron sands in the South Taranaki Bight.
TTR told the Chronicle yesterday morning that it was still considering its options but by that evening had announced it would be appealing.
"We have now studied the decision in detail with the assistance of our advisers and experts, and are confident that there are strong grounds for a successful appeal," TTR chief executive Tim Crossley said.
"We are not in a position to disclose the basis of our appeal as these will be sent to the EPA and submitters before being released by the EPA."
He said he would not be commenting further as the matter was being dealt with via a court process.
