Since geo-statistics developed by Prof George Matheron in 1960, it has been applied greatly in mining industry for mineral resources evaluation and reserves modeling. Geo-statistical method considers the spatial structure which is represented by variogram model in 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 geo-statistical method used for reserves estimation, and it has been known as BLUE (Best Linear Unbiased Estimator). Krigging variance can be applied to assess the uncertainly (error) of estimation result.

Beside kriging, there are any other geo-statistical methods employed for spatial characterization and modeling of natural resource such as conditional simulation. Geo-statistics can also be utilizing to evaluate mineral reserves classification.


  1. To give knowledge about the concept of regionalized variable that is the principle of geo-statistics method, analysis and interpretation of variogram.
  2. To give understanding about the principle of kriging method and its application for resources modeling and reserves estimation.
  3. To give introduction about the principle of geo-statistical simulation, uncertainly analysis, and their application in natural resources evaluation.
