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]
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 ...
This so-called three-part form of quantitative mineral resource assessments has been widely used. Among the places where they have been applied are the United States, Venezuela, [ 6 ] parts of Canada, [ 7 ] South America, Australia, [ 8 ] Finland, [ 9 ] and the Urals as part of a global assessment [10].
A Mineral Reserve includes diluting materials and allowances for losses that may occur when the material is mined. [3] Probable Mineral Reserve. A probable mineral reserve is the economically mineable part of an Indicated and, in some circumstances, a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study.
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. [6]
A mining feasibility study is an evaluation of a proposed mining project to determine whether the mineral resource can be mined economically. There are three types of feasibility study used in mining, order of magnitude, preliminary feasibility and detailed feasibility. [1]
GEOEV – geochemical evaluation report; GEOFO – geological and formation evaluation report; GEOL – geological surveillance log; GEOP – geophone data log; GEOPN – geological well prognosis report; GEOPR – geological operations progress report; GEORE – geological report; GGRG – gauge ring; GIIP – gas initially in place; GIH ...
