Hello
subscribers
I am interested in some of
the issues in dealing with using a cutoff grade on a conventionally kriged
block model which is significantly above the mean grade of the underlying sample
distribution and also the smoothed kriged block grade
distribution.
I would appreciate any
theoretical comments or practical information based on experience with using
cutoff grades which are above the average grade of the grade
distribution.
Issues such as incorrect
domaining, implications on mining selectivity spring to mind, however I am
unsure as to the full ramifications.
Best
regards
Mark
Sweeney
