A scoping study into the Galalar silica project, in far north Queensland, has estimated a price tag of A$24.4-million to develop the project into a 750 000 t/y project with an initial mine life of 15 years.
ASX-listed Diatreme on Monday reported that the project was estimated to have a pre-tax net present value of A$231-million and an internal rate of return of 150%, with an estimated capital pay-back of only eight months.
