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.
