For reserve estimation volume and density parameters must be included into calculations. To include the volume parameter into calculations the width of a block (on XY plane) must be obtained. Therefore, in order to obtain the influence area borders of cross-sections the same method, which was applied to the drillings, was applied to the cross-section paths.

The chapter reviews the non-geostatistical estimation methods, the most common of them, are polygonal, triangulation, cross-sectional and estimation by the panels (blocking). Another method which also described here is inverse distance weighting (IDW) technique.

The Statistical-Geostatistical model is a part of resource and reserve appraisal system. The traditional methods of ore reserve estimation developed based on the characteristics and value of the surrounding ground. The procedures do not consider any valid way to measure the reliability or uncertainty of the tonnage and grade. The chapter reviews the non-geostatistical estimation methods, the most common of them, are polygonal, triangulation, cross-sectional and estimation by the panels (blocking).

Reserve estimation is one of important work in evaluating a mining project. It is 2.1 Geostatistical Ore Reserve Estimation (By: MICHEL DAVID and ROGER A. BLAIST): Matheron's geostatistical method (the estimation of ore reserves) has been developed to the point at which real-life problems may be handled effectively. The steps involved in the method are as follows: i. Obtaining the variogram, ii.

Ore reserve and mineral resource estimation methods - current practices and comparisons September 2003 Conference: Mineral Management Information Centre, Ministry of Land and Resources A method of ore reserve estimation based on the assumption that a linear relationship exists between grade difference and the distance between all drill holes. Krumlauf Source: Dictionary of Mining, Mineral, and Related Terms The chapter reviews the non-geostatistical estimation methods, the most common of them, are polygonal, triangulation, cross-sectional and estimation by the panels (blocking). Another method which also described here is inverse distance weighting (IDW) technique.

reserve estimation process. Results indicate that the new approach used in reserve estimation process gives ~1.6% closer tonnages to the actual numbers and the grades are both ~1.6% closer to the actual values numbers when compared with the old system.

Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
