Snapshot	The Rocglen Mine was an open cut mine producing high-quality thermal coal from 2008 to 2019. Since late 2019, rehabilitation activities at the Rocglen site have focused on transitioning the previous mine to its post-mining landform. During FY24, Rocglen completed all major bulk earthwork required to establish the approved final landform. Work will now involve ongoing postrehabilitation monitoring and maintenance of the area, with site relinquishment expected to take at least 15 years until monitoring demonstrates the site is safe and stable. Rocglen is Whitehaven’s fifth previously mined site where rehabilitation activities have been completed.
