Snapshot	West Moreton Operations consisted of Jeebropilly, New Oakleigh and Chuwar. New Hope Group previously operated a number of coal mines at West Moreton, near Ipswich in South East Queensland. Following the closure of the last of these operations (Jeebropilly) in 2019, the Company progressed with rehabilitation activities and divested some of the land and mining leases. During 2024, the Company progressed towards divestment of the remaining West Moreton land assets and subsidiary companies, including the former Jeebropilly mine and its associated mining leases.

Summary:

Coal mined in the West Moreton area occurs in the central to upper part of the Walloon Coal Measures (primarily Jeebropilly Series) and contains locally named coal seams referred to as the Boughen, Butler, Cowell, Passe, Kathage, Wass and Haenke seams. These occur over an interval of approximately 120 metres and 43 individual plies are modeled in this sequence. The plies have an average thickness of 0.06-0.48 metres, with partings of up to 2.7 metres average thickness.

The rehabilitation area consisted of approximately 100 ha with a significant fall of approximately 100 m (average ˜10% slope) from the top of the catchment to the discharge point. During bulk earthworks, final profiling and the early stages of revegetation a number of erosion and sediment controls were implemented with a sediment basin required prior to the discharge point to capture sediment mobilised from the rehabilitation area and prevent non­compliant discharges. Using a traditional approach to sediment basin sizing, a basin volume of approximately 80 ML would have been required, which due to its size, would need to be a permanent feature of the final landform.

A HES basin was considered as an alternative to a traditional sediment settling basin and modelling found that it offered a much smaller volumetric requirement, with an improved proportion of stormwater treated and allowed a flow­through approach rather than batch capture and treatment of stormwater.
