The earliest methods used were all variants of the polygonal estimator, and typically, dilution and recovery were built into the estimation process to define an Ore Reserve without first progressing through the resource stage. As the importance of planning and scheduling of an opera- Ore Reserve Estimation of Saprolite Nickel Using Inverse Distance Method in PIT Block 3A Banggai Area Central Sulawesi Muhammad Khaidir Noor Mining Engineering Department, Universitas Pejuang Republik Indonesia, Makassar, 90234 E-mail: ipungnoor70@gmail.com Abstract. 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.

Se hela listan på wiki.aapg.org To estimate IBNR, with separate amounts estimated for pure IBNR and for IBNER or development on known claims, using methods similar to traditional triangle methods . Results. We applied several methods to our sample data set to calculate estimates that ultimately proved to be more accurate than traditional triangle methods. Conclusions 12 Dec 2017 Ore reserve estimation and grade determination is a significant phase In the triangular method, all sample points are joined to form a group of and no ore reserve estimate, no matter by what method it is achieved, is any better than the quality crucial to ore reserve estimation and is the raison d'etre of many methods. is expressed as a cross-sectional area i.e. thick 2.1 INTRODUCTION.

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 standard method of making these estimates is to find the cubic contents of triangular prisms, in the apexes of which the drill holes are placed, by multiplying the surface area by the average depth of the ore in the three drill holes and then multiplying the cubic contents by the specific gravity of the ore or rock to find the tonnage.

While the distribution used for the approximation might be a normal distribution, this is not always so and, for example a triangular distribution might be used, depending on the application. In three-point estimation, three figures are produced initially for every distribution that is required, based on prior experience or best-guesses: 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.

Using GIS, 3D model of the studied region, most suitable section planes and grade distributions were obtained and reserve estimation by cross-section method was approached. 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. Ore reserve and mineral resource estimation methods - current practices and comparisons September 2003 Conference: Mineral Management Information Centre, Ministry of Land and Resources resource estimation methods (e.g. polygonal, triangular, random stratified grids (RSG), or cross-sectional methods) rely on a few simple parameters, such as area, thickness and grade (based on chemical assay data).
