Warkworth Mining Ltd. v. Bulga Milbrodale Progress Ass’n Inc.  NSWCA 105
New South Wales Court of Appeal
A mining company applied to expand an existing open-cut coal mine, the Warkworth Mine, located in the Hunter Valley of the state of New South Wales. The company sought to mine areas that had previously been deemed uneconomical due to lower coal prices. These areas had been designated previously as “non-disturbance” areas under prior authorizations.
