Blackwater mine one of the longest coal mines in the Southern Hemisphere, with a strike length of 80 kilometers.
In February 2023, BHP announced together with Mitsubishi Development Pty Ltd, intention to pursue options to divest the Daunia and Blackwater mines. The process for this potential divestment is progressing in line with plans. |

Summary:
Bituminous coal is mined from the Permian Moranbah and Rangal Coal measures. Products range from premium quality, low volatile, high vitrinite, hard coking coal to medium volatile hard coking coal, to weak coking coal, some pulverised coal injection (PCI) coal and medium ash thermal coal as a secondary product.
Rangal Coal Measures of Late Permian age, dipping 3-5° to the east. Three major coal seams are present: Top (Aries) - 0.8-1.5m; Middle (Castor) - 2-3.5m; Main Lower (Taurus/Argo) - 5-7m. Complex seam splitting occurs along the 35km strike length of the mine.
