resource estimate is the critical fundamental foundation of all mining projects. All work done must be compliant with the relevant code i.e. SAMREC or JORC etc. Reserve estimates The reserve estimate gives an indication of the viability of the mineral resource.

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.
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.
In this document, we illustrate how to use statistical methods to estimate unknown values and create confidence intervals in the context of setting reserves for health (other than disability) insurance claims that have been incurred but not reported (IBNR). Two general statistical approaches used in developing estimates and corresponding confidence
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).
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.
