I'm not sure where you are getting the $.60 - $0.70 cost numbers from...  I doubt if those numbers have been updated for the new Operating costs numbers that we were just released 2 weeks ago.

If I used the old operating costs of $13.25 (not the updated one of $8.66) and those $1400 Au, 18$ Ag, 10$ Mo numbers.  Then I get $0.84 / pound.

But I wanted to estimate what the numbers would be based on new operating costs and more current metal pricing.
