I feel it is also important to consider that the 2 main DSO deposits are QUITE different in composition and so the final product/s sold to the market could be A, B or A+B or A+b or a+B.
I suspect (based on nothing but gut) that A is cheaper to get but not as attractive in composition B costs more to get but is an easier product to flog to the market.
My question is......Is A+B a better bussiness call (next 3 years till the port expands) or is the desire to get something to the port in order to create cash flow so strong that the blended option will be passed over?????
