The only colours that pertain to Kodiak are the pink/green/blue. The red are the old original stopes (? I have no idea if that is the correct term or not) from the Red Lak Mine. You can see that they continue down until just past the 1335 level. Actually, Goldcorp was stumped at this point becuase they lost the trail of the gold. That's when McEwen did the "who can solve this problem" test to the general public. They stepped the drills over to the left a few hundred meters and boom, the rest was history.

Brian Maher went over this in detail at PDAC.
