Mineral Estimates Reserves vs Resources — New Pacific

Mineral Reserves are sub-divided in order of increasing confidence into Probable Mineral Reserves and Proven Mineral Reserves. Mineral Reserves are those parts of Mineral Resources which, after the application of all mining factors, are the basis of an economically viable project after taking account of all relevant processing, metallurgical, economic, marketing, legal, environment, socio

Mineral resource estimation Wikipedia

Mineral resource estimation. Jump to navigation Jump to search. 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

Errors and Uncertainty in Mineral Resource and Ore

An Ore Reserve statement generally contains a single set of grade and tonnage figures without a discussion of the potential inherent errors in these estimates. Some sensitivity studies may be run, but confidence limits are rarely quoted and, if they are, often do not take into account many of the factors that cause uncertainty in the grade and tonnage estimates.

ASPECTS OF EVALUATING MINING PROJECTS

Mineral resources and ore reserves have been classified in vari­ ous ways and phrases such as 'possible', 'probable', and 'proven' or 'measured', 'indicated' and 'inferred'.have been used for many years (U.S. Bureau of Mines, 1980). Evaluations will normally be undertaken on indicated and infer­ red 'reserves'. The indication of continuity between samples allows the e valuator to estimate
