Hi, the beauty of this is that CHK hold all of the cards; drill, partner, sell, it's up to CHK.
A deep drill is not expensive when you know what's down there. The drill cost will pale into insignificance when you hit this sort of quantity and grade. Mining is another story, but that's what the economic assessment will work out.
Biggest point, bhp drilled deeper than anyone has before and struck gold! (Actually copper). All tenements could be sitting on a gold mine (copper mine) but if you ask me, I'll take the tenement next door.
