Mardie Salt & Potash
The Mardie Salt and Potash Project (Mardie or the Project) is 100% owned by Mardie Minerals Pty Ltd, a wholly owned subsidiary of BCI Minerals Limited (BCI). The Project represents a rare, sustainable opportunity to develop a large-scale, multi-generational solar evaporation operation on the Pilbara coast of Western Australia (WA).
About The Project
