Good points RBradley.
Guess you'd also have to take into account - grades, PGE content and other precious metals. I don't have comparisons between POS and SGQ, maybe you could provide them? Depth and mining technique would also play a part and so will nickel prices. If they rise to the heights we hope, all miners will be making cash.
If I was SGQ's CEO another tricky question I'd be asking myself is - do I drill out and JORC up the areas already known, or do I press on for the motherlode? I'm sure it was JP that said, "it's the first discovery that you're remembered by". This leads me to believe, for the moment anyway, he'll be pressing on.
If I was thinking about buying this stock, I'd be happy to know that there's an unquantified resource already found - of high quality - and that there's a fair chance of finding a whole lot more.
Good luck
