RE: shallow drillingKingbear, multiple drills are not the issue as I see it, but rather drill size. It would be problematic and prohibitively expensive at this juncture if EC were to reach for a large, powerful drill. The man-portable rig used in Phase I at Rio Z. used in conjunction with the MD-2 shallow diamond drill, which is basically just going to pinprick the area (to 200M), shouldn't cause any conflict.
