Its starting to make more sense now to me with this revised modelling. Given there is a "casual" or more likely a "formal" relationship between the Central Zone mineralization and that at the Eastern Mafic ( ie same origin of sorts) I previously had difficulty understanding how the feeder zone to the intrusion neck could be feeding the Central zone as well which is quite a distance away. Now that the revised model points instead to an underlying deeper nickel/copper source its not hard to visualize this being the primary source of both the Eastern mafic and Central Zone.
