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 New Hope Group operates an open cut, multi thin-seam mining operation at Jeebropilly. The Jeebropilly Mine is adjacent to the Amberley Air Base, 23 kilometres west of Ipswich and 92 kilometres from the Port of Brisbane. The mine has a long, rich history and association with Ipswich, having commenced operations in 1982.
