SnapshotThe Isaac River project, once operational, will produce high-quality, high-yielding metallurgical coal. Similar to the Bluff Mine, the project aims to use third-party processing and infrastructure facilities to fast-track the development of the mine once all approvals have been obtained.

Isaac River was granted a site-specific Environmental Authority from the Queensland government and holds an approved Progressive Rehabilitation and Closure Plan. At the end of May 2023, the Project was formally granted approval under the EPBC. The EPBC approval requires Bowen Coking Coal to offset potential impacts to ornamental snake habitats and to monitor surface and groundwater.

In 2023, Bowen Coking Coal announced it is investigating the potential sale of Isaac River as it focuses on its low-cost, longer-life Burton complex assets.

The Isaac River Project resource is located in the northern part of the Permo-Triassic Bowen Basin containing principally fluvial and some marine sediments. The Bowen Basin is part of a connected group of Permo-Triassic basins in eastern Australia which includes the Sydney and Gunnedah Basins. The economic coal seams are contained in the Late Permian Rangal Coal Measures which are approximately 100m thick. The Rangal Coal Measures are underlain by the Fort Cooper Coal Measures and overlain by the Late Permian to Early Triassic Rewan Group.

The Isaac River project area lies within the Permo-Triassic Bowen Basin. The Bowen Basin consists of 10 kilometre (km) thick sequences of volcanic, shallow marine and terrestrial sediments and is categorised back-arc to foreland basin.

The general stratigraphy of the project area includes (oldest to youngest):
-Coal seams occur within the Rangal Coal Measures and underlying Fort Cooper Coal Measures which are Late Permian in age. These seams dip to the east at approximately 7 - 25 degrees;
-The coal seams of interest found within the Project area are as follows – Leichhardt and Vermont Upper;
-Additional seams were intersected and in part analysed these were plies of the Vermont Lower and Girrah Seams.

The target seams have a cumulative thickness ofapproximately 7 m across the deposit. The underlying additional Vermont plies and Girrah seams have and additional 12m cumulative thickness.

The LHD target seam(s) extends approximately 1.8 km along strike and ranges from 300 to 600m across strike with an approximate average cumulative thickness of 4.4 m.

The VU2 target seam(s) extends approximately 2.1 km along strike and ranges from 400 to 700m across strike with an approximate average cumulative thickness of 2.4 m.

The depth of first coal ranges from between 25m in the south of the MDL, and 260m in the North at the hinge of the syncline.
