clueless
try some sophisticated mining software such as microsoft excel...you may have it..do a column for easting and one for northing and go to charts i think..then do an x y plot (not me that is ..get it xy..ha ha)..that gives you the basic 30m x 30m map where all the action is.
I think PP's maps may be a bit misleading as i think there are a lot more holes in those tiny blue circles.
