Agrimin Limited has reported an updated Mineral Resource estimate for the Mackay potash project in Western Australia.


  • Drainable Mineral Resource upgraded to 123 million t of sulfate of potash (SOP) (based on drainable porosity).
  • In-situ Mineral Resource exceeds >1 billion t of SOP (based on total porosity) and confirms Lake Mackay as Australia’s largest SOP deposit.
  • Mackay Potash Project is de-risked by an industry leading hydrogeological dataset, including over two years of trench pumping tests.
  • Ore Reserve scheduled for completion in 1Q20.

Mark Savich, CEO of Agrimin, said:

“We are delighted to announce a very significant upgrade to the Mineral Resource for the Mackay Potash Project. This is the culmination of several years of data collection and extensive hydrogeological modelling, which we believe to represent an industry leading level of rigour in de-risking the project. Importantly, the outcomes exceed the parameters used in the 2018 Pre-Feasibility Study. Lake Mackay is a world-class SOP project and we look forward to providing regular updates as we finalise the Definitive Feasibilty Study over the coming months.”
