Mineral resource classification is the classification of mineral resources based on an increasing level of geological knowledge and confidence. Mineral deposits can be classified as: Mineral resources that are potentially valuable, and for which reasonable prospects exist for eventual economic extraction.; Mineral reserves or Ore reserves are valuable and legally, economically, and technically ...
The Possible Reserve have the following characteristics:- A. The grade estimate of a possible reserve is a broad indication of the likely quality. B. The possible reserve contains only very general information on the mode of occurrence of geological structure and ore behavior. C.

Dec 31, 2000· Estimating Tail Development Factors 3.1 Equalizing Paid and Incurred Development Ultimate Losses This method is the first method discussed with a full theoretical background. It is most useful when incurred loss development essentially stops after a certain stage (i.e., the link ratios are near to unity or unity).
The method of estimation is called deterministic if a single best estimate of reserves is made based on known geological, engineering, and economic data. The method of estimation is called probabilistic when the known geological, engineering, and economic data are used to generate a range of estimates and their associated probabilities.

The JORC committee. The JORC Code is produced by the Australasian Joint Ore Reserves Committee ('the JORC Committee'). The JORC Committee was established in 1971 and is sponsored by the Australian mining industry and its professional organisations.
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.
Jul 13, 2016· 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.

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.

A PFS is a comprehensive study of the viability of a mineral project that has advanced to a stage where the mining method, in the case of underground mining, or the p configuration, in the case of an open p, g g, pit g, p pit, has been established, where an effective method of mineral ...
Nov 23, 2003· this is the practicality of the mining and processing methods proposed for the deposit. Best practice includes the use of peer reviews to test various aspects of the Mineral Reserve estimate including the inputs, methodology, underlying assumptions, the results of the estimate itself, and the test for economic viability.
Metallurgical ContentORE RESERVE CALCULATIONSMINERAL ORE RESERVE Case 1MINERAL ORE RESERVE Case 2MINERAL ORE RESERVE Case 3 The usual method of sampling mineral deposits is to drill holes and assay the sludge or core. Though the results thus obtained may not represent the true average value of the deposit, it is on these results that estimates of practically all .

actuarial literature. We propose to define the best estimate by describing a set of "best practices" -- many already found in the actuarial literature -- that a reserving actuary should follow, while minimizing the number of arbitrary judgments. Central to this paper is the recently introduced Generalized Cape Cod method. Many of these best ...
naturally occurring deposits in such forms and amounts that economic extraction is currently or potentially feasible (Wood et al., 1983). Coal reserve is a more restrictive term describing the part of the coal resource that can be mined economically, at the present time, given existing environmental, legal, and technological constraints (Wood et al., 1983).

Estimates of the tonnage and average grade of ore deposits (ore-reserve estimates) are made for various purposes. They may be made by examining engineers as a basis for placing a value on a mining property in connection with reports on behalf of owners or vendors, on the one hand, or for prospective purchasers or lessees, on the other.
