SnapshotThe Centurion mine (formerly known as North Goonyella, renamed in December 2023) was in operation until September 2018, when a fire halted operations in the mine.

During the third quarter of 2022, Peabody initiated the redevelopment of the mine. Development coal in April 2024 and sale of product coal targeted for H2 2024 (~100kt). Longwall operations are expected to commence in 2026. As of December 31, 2023, all required licenses and permits are in place for all activities for the operation of Centurion.

Centurion Mine will extract coal from the Goonyella Middle seam with future plans to extend into the Goonyella Lower B2 (GLB2) seam. Centurion Coking coal is a premium Hard Coking Coal (PHCC).

Summary:

The Centurion Mine lies on the Collinsville Shelf on the western margin of the Bowen Basin in Central Queensland. The regional stratigraphy of the area comprises the Permian Blackwater Group which comprises three coal bearing sequences, the Moranbah Coal Measures (MCM), the Fort Cooper Coal Measures (FCCM), and the Rangal Coal Measures (RCM, it also contains the Triassic Group sediments (Rewan and Clematis) and Tertiary sequences. The Centurion Mine lease covers the subcrops of the Moranbah and Fort Cooper Coal Measure sequences. The Permian strata were overlain by Triassic Rewan Group and Clematis Group sediments, however in the Centurion area the Triassic sediments have all been removed and a large unconformity exists between the Permian and Tertiary sediments. The main seams of economic interest are the Goonyella Middle and Goonyella Lower B2.

The coal seams of interest (GM and GLB2 seams) occur within the Permian Moranbah Coal Measures in a structurally complex zone on the Collinsville Shelf in the northern Bowen Basin in central Queensland, Australia. The stratigraphy gently dips between 4 and 5 degrees towards the northeast and the GM seam averages 6.1m thick. The GM and GLB2 seams are considered medium volatile bituminous by the ASTM Classification of Coal.

The Moranbah coal measures occur within a cyclic fluviatile clastic depositional system, that consists of regular fining up sequences of lithic sandstones, siltstones, and mudstones to coal, then coarsening up sequences in the opposite manner.

The coal deposit type of the Centurion mine is considered to have a moderate geologic complexity based on the following factors:
• The Goonyella Middle and Goonyella Lower B2 seams are laterally continuous and can be correlated across the property with the use of geophysical logs, interburden thicknesses, and seam thicknesses.
• The seams are gently dipping with some seam splitting experienced within the Goonyella Lower seams.
