People did the same calculations as you are doing with CMM -SPR - CYL - OBM - and a dozen more with multi -billion dollar market caps -yep multi billion caps all in the short space of only months -a year or two maybe -- NMG will have a similar market cap like those I mentioned quicker than you can say Jack Robinson mate not a market cap of $200 million once mining as you propose. Well at least you are on board but throw away your calculator -it simply doesn't work like that -why I love WA gold plays once on a roll it happens mighty fast - You have to stick your neck out in this game - most of these ore systems deliver -look at Meeka -why did Alan Kelly walk away from that He thought he only had a small ore system - Or all the oz's GBR are finding if only they had the smarts to do what NMG are doing and negotiate toll milling. Ironbark alone huge cash flow if Patto would mine the stuff.
The Abbots greenstone belt and all its shear related gold -Crown Prince is just the tip of the iceberg -it's a huge belt of country and better still things like Lydia are screamers to replicate Crown Prince.
