Mineral resource estimation - Wikipedia

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.

Mineral resource classification - Wikipedia

Mineral resource classification is the classification of mineral resources based on an increasing level of geological knowledge and confidence. In an effort to achieve a standard set the classifications, representative bodies from Australia, Canada, South Africa, the USA and the UK reached a provisional agreement in 1997 on the definitions of each of the various mineral classifications.
