For transparency the development concept for Karinga Lakes Potash Project, which is the only project example that has been made public that I am aware of, does not show the total elimination of the evaporation ponds.

Upstream Operations

• 1 - Brine Harvest – extraction of raw brine from trenches and pumping to evaporation ponds.

• 2 - Brine Concentration – the raw brine is concentrated, through a i) pre-concentration pond, then pumped to, ii) a Halite crystallisation pond, where waste sodium salts are precipitated, and then pumped to the, iii) final potassium salts crystallisation pond, where the potassium enriched mixed salts are harvested.

• 3 - Salt Stockpile - the harvested potassium enriched mixed salts, are then transported a short distance to a stockpile, near the processing plant, ready for processing in the SOP processing plant.

• 4 - Process Plant – the aMES™ based process plant, then processes the potassium enriched mixed salts, to produce SOP, which is then packaged on-site.

• 5 - Site Logistics – packaged SOP is then transported to key domestic markets, via the proposed access road leading to the Lasseter Highway to the north of the project area.
