Frank, you might not beleive this but I was contemplating asking views on the same thing and was just about to post.
I figured 2b t from Karara and say 1b t 'possibly' from Lodestone, giving the 3b t you mentioned, and what peoples thoughts were in regard to what sort of market cap they would expect GBG to have if they actually state similar to the above mentioned resources.
Looking at it another way and going on GBG's figures, this would make GBG the equivalent of a Hematite mine 5-600k from the coast with a hematite resource of approx. 1.2b t.
What market cap should GBG be running at based on that?
