Hole effect model, usually means your deposit has
alternating high and low grade zones. Sorry I'm not
familiar with the geology of this deposit but examples
of this could be pods of high grade spaced apart from
each other with waste or low grade halos between
them. If only the high grade zones are

Dear Rajive:
I cannot conclude with only 328 pairs that the feature is "wavy" because I do not know how those pairs are distributed for each point in the variogram. Try different lag spacings, or create an "equal-n" lag variogram where each lag has the same number of pairs. If that shows th
