Mardie Minerals Pty Ltd has approval to develop a greenfields high quality salt and SoP project and associated export facility at Mardie, approximately 80 km south-west of Karratha, in the Pilbara region of WA. The project will produce a high purity salt product, Sulphate of Potash (SoP) and other products that can be derived from sea water.
The Proposal includes the expansion of the approved Mardie Project (Ministerial Statement [MS] 1175) including expanded concentrator and crystalliser ponds, an increased salt and SoP production rate, new secondary seawater intake option, a port facility laydown area, a quarry, and minor changes to the dredge channel.
The Proposal is a significant amendment to the Original Proposal approved under MS 1175, specifically to:
-
Increase the Terrestrial Development Envelope by 3,978 ha.
-
Increase in disturbance within the Terrestrial Development Envelope by 2,334 ha.
-
Increase in project throughput, which includes:
-
Increase in seawater intake to 180 GL/a.
-
Increase in brine discharge to 5.5 GL/a.
-
Increase in export volumes to 5.35 Mtpa of salt and 140 ktpa of SoP.
-
Inclusion of another secondary seawater intake option within Mardie Creek.
-
Minor alteration of the dredge footprint and methodology within the Dredge Channel Development Envelope (10-ha increase in dredge disturbance footprint but no change to dredge volume).
-
Increase the Dredge Channel Development Envelope by 3.5 ha.
-
A quarry adjacent to Mardie Road.
