You start from the surface and follow it down. Which is what we're doing. The magenta area on Figure One starts at about 175m depth. It is the new high grade zone at depth the NR mentions. Systematic drilling finds that.
Systematic drilling yields many holes with unglamorous results but like a painting has foreground and background, the unglamorous holes are background for the main elements in the foreground like this new high grade zone.
I remember Virginia results that had many unglamorous holes as well, and many with no gold at all. We're finding gold everywhere we look.
