Much more than $0.69 but it is difficult to quantify. I think CUU will need to do some heavy reoptimization of the BFS before a construction decision can be made. Someone needs to demonstrate concrete synergies in this mining district in regards to infrastructure (i.e. reduce capex). And more exploration is needed to prove up the inferred and add other zone that can improve the grade in the earlier periods (i.e. reduce opex/improve economics).
Greater feats have been done (look at KGN and adjust for its cash - the company had an EV of nearly zero post a disasterous PFS but was able to come back quite nicely with a reoptimized mine plan).
