ore reserve estimation methods

METHODS OF ORE RESERVE ESTIMATION_EXAMPLE Basic

Value and extent of a mineral deposit can be estimated using classical methods or geostatistical methods. The simple yet accurate ore reserve estimation technique used is classical methods. Classical methods employ simple geometric function and rules that are easily applied to simple uncomplicated orebodies.

Geostatistics and resource estimation techniques

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 (see below) used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.

Geostatistical Ore Reserve Estimation Tutorial Geology

Jul 15, 2017· The development of geostatistics as an ore reserve estimation methodology emerged in France in early 1960 from the work of Matheron (1962) and was based on original studies by D.G. Krige functioning the optimal assigning of weights to the neighbouring sample values used in estimating the grade of blocks in South African gold mines.

Reserves estimation AAPG Wiki

Feb 17, 2016· Estimating hydrocarbon reserves is a complex process that involves integrating geological and engineering data. Depending on the amount and quality of data available, one or more of the following methods may be used to estimate reserves: Volumetric Material balance Production history Analogy These methods are summarized in Table 1.

when combined, cause significant uncertainties in the reserves estimate. As production and pressure data from a field become available, decline analysis and material balance calculations, become the predominant methods of calculating reserves. These methods greatly reduce the uncertainty in reserves estimates;

Ore reserve estimation using localized trend analysis

Jul 01, 1988· The techniques used in ore reserve estimation vary from the simple method of polygons through heuristics such as distance weighting methods to quite sophisticated kriging procedures of geostatistics. The results from the method of polygons are usually inferior to those of both the heuristics and geostatistics.
