Brazil Potato and Tomato Crop Study Results

The Directors of Sirius Minerals Plc (AIM: SXX, OTCQX: SRUXY) ("Sirius" or the "Company") provide an update on the latest results from its ongoing global crop study programme.

This update provides results from independent studies undertaken in Brazil on tomato and potato crops at the University of Sao Paulo. The Brazilian market for tomatoes accounts for 66% of a US$4.79 billion South American tomato crop market. Brazil also supplies 22% of the US$6 billion South American potato crop. Highlights from the trials include:

-- Polyhalite applied as a straight fertilizer improved tomato yield by 6% over the control and 15% as a blend component;

-- Tomato quality measured as Brix, pH and fruit firmness indicated improved taste and shelf life potential;

-- The potatoes grown using a polyhalite blend achieved the same yield using 68% less product than the local commercial option; and

-- A polyhalite blend option offers a lower cost, higher nutrient content and is a more efficient product than a commercial alternative.

Chris Fraser, Managing Director and CEO of Sirius, commented:

"Tomatoes and potatoes are two very large markets globally and these results further demonstrate that polyhalite provides the farmer with an economical option to lower input costs, increase yields and get an overall better quality product."
