A Probable Mineral Reserve is the economically mineable part of an Indicated Mineral Resource, and in some circumstances, a Measured Mineral Resources. It includes diluting material and allowances for losses which may occur when the material is mined. A Probable Mineral Reserve has a lower level of confidence than a Proved Mineral Reserve but ...
Mineral 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 used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
Classification and management of natural resources such as minerals and petroleum are classified using differing schemes. [4] [5] In 1997, UNECE published the United Nations Framework Classification for Reserves and Resources of Solid Fuels and Mineral Commodities (UNFC-1997) as a unifying international system for classifying solid minerals and fuels.

Logo of the PERC - PAN-EUROPEAN RESERVES + RESOURCES REPORTING COMMITTEE . The PERC Standard for Reporting of Exploration Results, Mineral Resources and Mineral Reserves (the ‘PERC Reporting Standard’) [1] sets out the minimum standards, as well as additional guidelines and recommendations for the Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves within Europe.
An ore deposit is an economically significant accumulation of minerals within a host rock. [9] This is distinct from a mineral resource in that it is a mineral deposit occurring in high enough concentration to be economically viable. [4] An ore deposit is one occurrence of a particular ore type. [10]
The study is primarily focused on metallic mineral deposits and mineral resources. The techniques employed by other Earth science disciplines (such as geochemistry , mineralogy , geophysics , petrology , paleontology and structural geology ) might all be used to understand, describe and exploit an ore deposit.
Money market funds earn higher base returns, starting above 1%, with some funds paying up to 4.00% or more. With a fund, you risk losing money if the market takes a severe downturn.
Vogely has stated that the development of a mineral resource occurs in five stages: (1) The current operating margin (rate of production) governed by the proportion of the reserve (resource) already depleted. (2) The intensive development margin governed by the trade-off between the rising necessary investment and quicker realization of revenue.
