An economic analysis of the Dolphin tungsten mine, in Tasmania, has estimated that the project would cost some A$65-million to bring into development.
ASX-listed King Island Scheelite on Tuesday reported that based on the currently planned opencut operation, which is projected to produce some 20 t/y of tungsten over an eight year mine life, would have a net present value of some A$153-million and an internal rate of return of 46%, with a capital pay-back period of just under three years.
