Still reckon they need to follow down at depth the near surface high grade Copper zones already identified. That copper has risen from somewhere below so surely the logical step is to follow it down to have more chance of finding the motherlode rather than a wild-cat single deep hole based solely on gravity/magnetics. at depth. It was long shot. There is a 3-D graphic I saw where the gravity/magnetic body appears to be some distance away from the near surface copper hits. It struck me as rather odd at the time in regard where they then planned the deep hole. Back to basics..... follow the copper zones down deeper.
