Mardie Minerals Pty Ltd proposes to develop a high volume salt and Sulphate of Potash project at Mardie, approximately 80 km south west of Karratha, in the Pilbara Region of Western Australia. The proposal would utilise seawater and evaporation to produce a concentrated salt product and other associated products.
The proposal includes a seawater intake, evaporation ponds, processing plant, bitterns disposal pipeline and outfall, desalination plant, freshwater supply bores and associated infrastructure. The only waste product would be approximately 3.6 GLp/a of bitterns.
The proposal would include disturbance of up to 9,365 hectares on shore, and up to 40 hectares of marine environment.
