The firm based its financial modeling on a 4 million tonne a year run of mine operation producing 2.2 million tonnes of saleable coking and thermal coal.

This generated a net present value of $662m and an internal rate of return of 79.5% under a 11.5 year mine life.

The project capital costs are estimated at $166m, or reduced to$18m using the Group’s build, own, operate model.

Currently, the project has a JORC mineable reserve of 42.65 million tonnes, including a marketable reserve of 23.46 million tonnes, of which 8.72 million will be coking coal.
