There are several classification systems for the economic evaluation of mineral deposits worldwide. The most commonly used schemes base on the International Reporting Template, [1] developed by the CRIRSCO - Committee for Mineral Reserves International Reporting Standards, like the Australian Joint Ore Reserves Committee - JORC Code 2012, [2] the Pan-European Reserves & Resources Reporting ...
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.
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.

A Mineral Reserve is the economically mineable part of a Measured or Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can ...
Quantitative mineral-resource assessments are defined as the numerical estimate of the amount, quality, and in some cases, value of undiscovered minerals (that is, metal or industrial mineral) present within a specified area (tract). Their purpose is to provide a framework for making decisions by governments or institutions concerning mineral ...
Diagram as published by McKelvey in 1973 [1] Diagram as published by McKelvey in 1976 [2]. A McKelvey diagram or McKelvey box is a visual representation used to describe a natural resource such as a mineral or fossil fuel, based on the geologic certainty of its presence and its economic potential for recovery.
QEMSCAN is the name for an integrated automated mineralogy and petrography system providing quantitative analysis of minerals, rocks and man-made materials. QEMSCAN is an abbreviation standing for quantitative evaluation of minerals by scanning electron microscopy, and a registered trademark owned by FEI Company since 2009.
National Instrument 43-101 is comparable to the Joint Ore Reserves Committee Code (JORC Code) which regulates the publication of mineral exploration reports on the Australian Securities Exchange (ASX). It is also broadly comparable with the South African Code for the Reporting of Mineral Resources and Mineral Reserves (SAMREC). [1]
