Ann: Company Presentation-SO4.AX, page-6

I guess the only comparable is both claim to be the leading supplier of potash for the future. who will get there first with the infrastructure remains to be seen but Salt Lake also have many Lakes untested not just there golden goose in Lake Wells and the scarceness of stock in s04 gives it the nod over RWD for me and the quantities of Potash it should be able to produce.
I did read that the boys @ SO4 were tipping a SP in the future of $5.70 which doesnt seem far fetched seeing what prices other SP's are around the globe of supplying Potash up in the $20+ bracket whether it be Africa, Germany or Canada. I got in at $0.15 and have seen it up to $0.55 so still has a long run yet when production occurs should soar high this one.
its found support @ $0.40 tracking sideways which is positive as last support was down at $0.33 so yeah positive.
