Most mining activities depend on the grade and tonnage of ore reserves; therefore, it is significant to know the validity of estimating the grade and reserve of ore deposits. A key parameter in determining the quality of grade estimates in modeling the reserves is the block size. The main purpose of this research is to estimate the grade of …

Mineral resource classification plays an important role in the downstream activities of a mining project. Spatial modeling of the grade variability in a deposit directly impacts the evaluation of recovery functions, such as the tonnage, metal quantity and mean grade above cutoffs. The use of geostatistical simulations for this purpose is becoming …
