The project is located on the north-western flank of the Bowen Basin, a sedimentary basin comprising Permian to Triassic age geology.

The majority of coal is mined from the German Creek Formation, which contains five coal seam intervals known as the German Creek, Corvus, Tieri, Aquila and Pleiades seams.

In these areas, the creeks are typically incised into the landscape exposing the underlying rock in the creek bed and banks. Where present, there is typically less than 5 m of alluvium in the creek beds. Floodplain alluvial deposits are localised to the inside of meander bends and areas where the creek is less incised. In these areas the floodplain alluvium typically ranges from a few centimetres to 4 m thick. Alluvium is not present outside this localised area of creek and floodplain deposits.

Capcoal comprises opencast operations at Lake Lindsay and Oak Park.
