Actually, holes 5, 6 and 7 were the three holes from this program that twinned historical hole locations (to confirm suitability of the historic holes for inclusion in the new JORC compliant model) and thus you'd expect those 3 holes to pretty much match the expected seam thicknesses.
6 and 7 were pretty much smack on the expected, but interesting to note a 46% increase at 5. Surprise increases are always nice I suppose. :)
