I think Flying Fox mine in Australia has ridiculous grade at depth but I am fairly sure there is almost no tonnage.

Bottom line is although Mucker made several factual errors (Kidd being a copper mine as opposed to a nickel mine being a major one), s/he (although I doubt there are to many women who have been in mining for 40 years). He was right about one thing unless the size of the lenses (either width or along strike) increase with depth (i.e the deposit gets a lot bigger as it goes down) there is not a huge likely hood of this deposit being mine at Creighton/Kidd depths. There would just be too much capital put in for 3,000,000 to 4,000,000
