Institut Teknologi Bandung (ITB)

1. Introduction
Since geostatistics developed by Prof. George Matheron in 1960, it has been applied greatly in mining industry for mineral resources evaluation and reserves modeling. Geostatistical method considers the spatial structure which is represented by variogram model in estimation. Therefore it is leading compared to the conventional reserves estimation methods such as polygonal, triangular grouping, inverse distance square, nearest point, etc. Moreover, parameters of variogram model can be drawn on to optimize the drilling pattern or the influence area of sampling points.
Kriging is the most famous geostatistical method used for reserves estimation, and it has been known as BLUE (best linear unbiased estimator). Kriging variance can be applied to assess the uncertainty (error) of estimation result.
Beside kriging, there are any other geostatistical methods employed for spatial characterization and modeling of natural resources such as conditional simulation and multivariate geostatistics. Geostatistics can also be utilizing to evaluate mineral reserves classification.
