I briefly looked though their BFS and a few other WA fertilizer upstarts. The science seems pretty straight forward - collect water, evaporate water, collect salts, concentrate salts in to high quality fertilizer, ship and sell fertilizer. Anyone who lives in WA knows collecting and evaporating water is pretty easy. Collecting the evaporated salts is pretty easy. Concentrating and separating the different salts requires processing equipment that I think is relatively standard or common overseas from a chemical process. No one seems to have built it yet in Australia which is where some issues have crept in (KLL said something like 'complexity of bringing German design to outback' or similar). If they have had building difficulties - then presumably there will be commissioning difficulties.
Without other Australian examples is nearly impossible to estimate the accuracy of their capital costs and operating costs. One would think the transport costs would be massive as trucking that stuff to port wont be cheap. There are so many others doing this, agrimin, SO4, APC, RWD, DNK, but KLL I think is the furthest advanced.
I pulled an order at 13 cents earlier in the week. I was wrong earlier thinking this would not fall below 15 cents, but it did. Obviously some nervous holders, and rightfully so - potash supply has been taken off market lately as prices have not been great, and most of these aspiring producers did all their fancy presentations and feasibility numbers when the outlook was better. Probably some good opportunities in this sector, but need to see more positive results and updates #'s, rather than marketing and self promotion.
