"The TCM project had a mineral resource estimate of about 129.16-million tonnes, and was expected to deliver 1.5-million tonnes a year of saleable coal product over a 30-year mine life.

A 2012 feasibility study estimated that the base case production would require capital expenditure of $179-million, excluding mine closure and ongoing maintenance costs. The feasibility study estimated that the project would have a net present value of some $124-million, and an internal rate of return of 20.85%."
