I have not looked into the value of Cs, but we must remember, a good percentage for the final value in any mineral is wiped out by mining/processing cost. If say we do get $20,000 per tonne of Cs, expect say $18,000 have already been burnt in producing the stuff.
Having said this, if we find many tonnes, then big money is to be made. We really need to find a super big deposit.
I see no reason in this area why we can not find a big orebody, and the grades are looking interesting, which is a major factor.
I think PIO are on a smart direction here.
