SnapshotThe Gregory Crinum coal mine was originally an open-cut mining operation that later added underground mining at Crinum Mine.

Gregory Crinum is proposing to continue mining to M-Block, an area west of the existing mining area. Open cut methods will be used for the first three years before going underground. The extension will extend operations for up to 20 years.

As of September 1, 2023, Sojitz Blue Pty Ltd has won federal environmental approval for the M-Block project to extend Gregory Crinum coal operations.

Summary:

The Bowen Basin in Central Queensland contains most of Australia’s high quality metallurgical (coking and pulverised coal injection (PCI)) coal reserves, as well as significant deposits of thermal coal.

Bituminous coal is mined from the Permian German Creek Coal measures.

The Gregory Crinum Mine is located within the Early Permian to Middle Triassic structural framework of the Bowen Basin foreland. Deposition in the Bowen Basin commenced during an Early Permian extensional phase, with a thick sequence of coals and non-marine clastics being deposited to the west. Rifting was followed by a phase of thermal subsidence from mid-Early to Late Permian, during which a basin-wide transgression allowed deposition of extensive coal measures.

The regional stratigraphy surrounding the M Block supports three dominant geological formations. The east and south-east are dominated by the Permian Fair Hill Formation, Fort Cooper Coal Measures (Pwt). This is a composite unit consisting predominantly of sedimentary rocks with a lithology of sandstone, conglomerate, mudstone, carbonaceous shale, coal and cherty tuff. To the west and north is the Late Permian German Creek Formation (Pbd), a laminated unit consisting dominantly of arenite mudstone with a lithology of quartzose to sublabile, locally argillaceous sandstone, lithic and feldspathic sandstone, siltstone, mudstone, carbonaceous mudstone and coal. The site is underlain by the stratified Late Permian McMillan Formation (Pbn), which is predominantly arenite mudstone with a lithology of mudstone, siltstone and sandstone.
