Coal mining activities ceased in April 2013 and all mining equipment was removed from site. No coal mining was undertaken during the 1 November 2020 – 31 October 2021 reporting period or is planned during the next reporting period.
Donaldson remains on care and maintenance and technical work remains ongoing to assess potential future mining operations. Based on the latest available technical information, with development commencing in 2025, and adopting a 14% discount rate, the recoverable amount exceeds the book value. |

Summary:
Limited coal extraction has been conducted from the Fassifern Seam where it is exposed around the hillside of the Tasman deposit.
The 30m to 110m thick Tomago Measures include the previously mined Great Northern Seam which lies from 7m to 30m above the proposed workings and by the West Borehole Seam that lies approximately 150m beneath the Fassifern Seam.
The overburden typically comprises several conglomerate units with interbedded siltstone, claystone and sandstone overlying the Great Northern Seam, the Awaba Tuff and Fassifern Seam and dip at <5° towards the south-east.
Summary:
Donaldson’s coal operation was moved to a “care and maintenance” phase and feasibility studies have been commenced to explore potential future mining options including the introduction of a longwall mining method.
Mining ceased at the Abel underground mine in June 2016.
No further mining will be undertaken.
All rehabilitation works have previously been completed. Any rehabilitation works during the 2020/2021 reporting period will relate to ongoing maintenance, principally erosion and sediment control, weed management and vegetation establishment, as required.
