RE: Nash FeasibilityThat's a fairly good question, cause I've been brooding about that too back in March when there weren't any glimpse of hope for an upside swing in the SP. One would thing that with $700 mil+ of stuff in the ground all you need is to get some agreement with the mill and smelter owners, bring in some heavy digging machinery and start whacking. And then use proceeds to fund further exploration efforts.
The only apparent reason I could come up with was that even an open-pit mining still requires a good deal of capital expenditures and the only way to get that capital is to issue more shares or to borrow from the bank. And the bank would only lend after seeing a 'bankable feasibility study'...
Would be interesting to see the insights on this matter of those who have seen a few progressions of deposits into working mines throughout their investing career.
Cheers!
