Feasibility study, page-5

Got a price from my supplier this morning.

KCL Fertiliser grade - muriate of potash, current retail price in Perth is about A$790 / ton

K2SO4 (SOP) is A$ 1040 / ton

Those prices exclusive of GST but include delivery of about $30 / tonne

Its the difference that's relevant here, so about A$250 more for the SOP.

Also need to consider amount of each my supplier sells, value of $A when he bought it,

whether grades are comparable etc.

Anyway the claimed difference of $300 - 350? is probably correct.

Regards to all STB holders.

Big year ahead methinks!
