So if EMH sell Carbonate at the same price as SQM instead of the PFS price, keeping the tonnage the same at 20,800t/pa They'd have an extra $136,614,400 in the bank......
Of course it's risky. That's the whole point in investing in small market cap AIM shares. Bigger risks equal bigger reward. Why don't you go invest in Apple or Facebook mate. You're in the game.
