A total of 581ha of rehabilitation has been assessed as meeting completion criteria, representing more than 40% of the site's rehabilitation work.

The latest certification is across three areas and includes the Bootes Creek Diversion, the first time a Glencore site has achieved sign-off on this type of rehabilitation.

Rolleston operations manager Paul Sear said Rolleston submitted 60ha of land that would support cattle grazing, 45ha of native grassland and 88ha of the Bootes Creek diversion work, which would also be used for grazing.

"Meeting closure criteria on more areas of our rehabilitation is the culmination of years of effort," he said.

"Our employees really do take enormous pride in this aspect of mining. Many of them are from rural backgrounds and they appreciate the importance of returning land to productive and sustainable uses once mining activity is complete."

The latest certification represents the tenth successful application for sign-off by a Glencore coal operation and the eighth at a Queensland site, following previous certification for 211ha at Newlands, almost 400ha at Rolleston, 99ha at Collinsville and 565ha at Oaky Creek.

NSW sites Westside and Ulan also achieved sign-off on areas of rehabilitation.

Glencore environment & community director John Watson said a number of sites in both Queensland and New South Wales were preparing submissions for further certification.

"We place high importance at all our sites on completing rehabilitation as soon as possible on land no longer needed for mining activities," he said.

"The latest achievement by Rolleston underlines the value of that approach.

"We've been able to achieve completion criteria - such as landform stability, water management, established vegetation and sustainability - while the site is still operational.

"In fact, some of the certification applies to areas that were being mined less than 10 years ago."
