Abstract: 

Reducing the estimation error in reserve estimation of mineral deposits is of vatial importance for the commericial and technical future of a mine. In traditional ore reserve estimation in addition to low level of precise estimation, deriving error distribution function is impossible, whereas in geostatistical assesment methods using variability modeling, precision of estimates rises, error declines to minimum and error distribution function calculation is feasible. In this article the CaO value datum has been evaluated spatially in all of the mine (sampled and not sampled locations) through classic statistics, proper transformations, calculating variability of data, modeling variabilities and ultimately calculating estimates and corresponding errors related to every mineral block estimation and related maps were drawn.
