Approximately 108,000 tonnes of contained SOP pumped as at end June 2021108,000 x $500 = $54,000,000

Confirmed reserve = 1,650,000
Probable reserve = 3,490,000
Total probable = 5,130,000
Total confirmed worth = 1,650,000 x $500/t = $825m
Total probable worth = 5,130,000 x $500/t = $2.565b

This is my current evaluation, if you would like to add or correct please do.

I have used $500/t as a good estimated price on potash even though it is saying it's currently being traded at $600/t.
