    Thegooch,

    I downloaded an ebook suggested on HC in which the author said underground mining (which I think is the only viable method at this depth) required grades >5g/t. These intersects are less than that? Or is the rule of thumb in the ebook to be applied if the strike is underground with no open pit above....that is, you need to tunnel down hundreds of meters to START mining gold?

    The ebook I read is called Understanding Gold by Jason Barnett.
