An optimisation of the prefeasibility study (PFS) for the Mardie salt and potash project, in Western Australia, has improved the project economics, with a definitive feasibility study (DFS) now targeted for late 2019.
ASX-listed BCI Minerals on Friday reported that the optimised PFS estimated a pre-tax net present value of A$560-million, which compared with the A$335-million estimated in the 2018 PFS, while the internal rate of return has remained unchanged at 20%.
