I don't concur with Alex Cowie's deductions. I reckon the surface tests for Potash grade will be fairly accurate and could be below 30% let alone 35-37%. Regarding the 'thickness' he doubts the wording. I am not basing my decision re buy/hold/sell on one recent drillhole. Instead I'm using info from the 10-20 drillholes from 20+ yrs ago.
