That's the beauty of this play: it doesn't matter that they're drilling 20 KM away. They are drilling on a primo location, with all the right magnetic signatures.
I know there will be folks who say it does matter that they're drilling so far away, but I don't think they quite grasp the geology of the area. Once BMK hits 20 km away, we're off to the races because the majors will really take notice then off just how massive this find is. Unfortunately, then all sorts of scammers will come along and claim to have mineralization as well.
The BMK website is chock-full of goodies for anyone who takes the time to look: go to www.macdonaldmines.com and click below the IMPORTANT LINK on the Macdonald presentation. Pages 6 and 7 where you see the dark purple bits is what BMK has scouted out and snapped up. You'll really understand why they call it the "Ring of Fire " after that.
Just my two bits
