Ann: Positive Scoping Study for the Mackay SOP Project-AMN.AX, page-15

Sorry DDZX, you must be a politician. The question raised is in the presentation - you have simply given the same information presented a different way. Does anyone know why RWD quote an in brine and an in situ measure and why one is half the other? As a FURTHER example please see the results table at http://rewardminerals.com/index.php/investors/asx-announcements 12 November 2015 Aooendix 2: In-Situ Assay Results.
The rule of thumb with SOP is K grade x 2.23. Do your own calcs on the K grades in this results table and see what you come up with. The derived K2SO4 grades are NOT K x 2.23, but K x some other factor. This is why it is reasonable to say that RWD use a different measure (NOT UNIT) to measure their SOP grades.
