Agrimin Limited has provided an update on the pilot evaporation trial and product development activities for its 100%-owned Mackay potash project in Western Australia.


  • Definitive feasibility study (DFS) process design confirms targeted sulfate of potash (SOP) and sulfate of potash magnesia (SOPM) product specifications with an 80% overall process recovery (brine extraction to product)
  • DFS pond model validated by a full year of data collection from the pilot evaporation trial
  • Larger batches of SOP and SOPM product samples dispatched to several potential off-takers
  • DFS on schedule for completion in 2Q20

Mark Savich, CEO of Agrimin said: “We are delighted to announce the excellent results achieved from the first full year of operations at our long-term pilot evaporation trial on Lake Mackay. This trial has successfully validated the Definitive Feasibility Study pond model and process assumptions, which is another major de-risking milestone for the project.”

“We have now harvested over 50 t of raw potash salts which continue to produce SOP and SOPM samples from pilot tests that exceed the targeted specifications outlined in our product specification sheets. These samples have been progressively distributed to potential off-takers and project partners.”
