Abstract
Reserve modeling is one of the essential aspects of exploration activity. Reserve modeling of
ore commodities has classic challenges such as grade distribution and quantity of the ore
reserve. This study introduced a novel reserve modeling protocol incorporated kriging
methods for nickel laterite deposits. The study parameters consist of geological modeling and
statistical analytic using the ordinary kriging method and nearest neighbor polygon. This
study shows that the ordinary kriging method has a conservative estimation compared to the
nearest neighbor polygon. Besides, the rectangular drilling pattern is the most suitable
drilling pattern for the exploration activity of this study.
