This is Mining Lease ML70378 which is for the Grosvenor Coal mine which is owned by Anglo American and built with an initial 1.95bn investment. The mine is estimated to produce seven million tonnes of run-of-mine coal per year. This coal will be processed to produce around five million tonnes of coking coal per year for export and the Life of Mine (LOM) is expected to be at least 26 years.

The coal seams in Bowen Basin resemble deposits of the Permean, Triassic, and Jurassic periods. They extend 600km-long and 250km-wide. There are estimated to be 139 million tonnes of metallurgical coking coal reserves at Grosvenor Mine. The Grosvenor Mine is being developed using the longwall method. Mining will mainly occur at the Goonyella Middle coal seam.

For access to the mine a 980m-long conveyor has been built to transport the coal to the surface. Coal will then be transferred to the handling and preparation plant at Moranbah North Mine for processing, where it will be crushed, sized, and washed at the coal handling and preparation plant (CHPP).

Construction started in July 2012 and the first developmental coal batch was shipped in 2015. The conveyor tunnel boring was completed in 2014, while the person and equipment tunnel was completed in February 2015. The first phase consists of developing an underground longwall mine, which is scheduled to be commissioned in 2016. The second phase will involve the addition of a second longwall. Prefeasibility studies are being carried out on the second phase.
