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.
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 ...

Mineral Reserves are subdivided in order of increasing confidence into Probable Mineral Reserves or Proved Mineral Reserves. 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 ...
The technical information required in a Reserve declaration under NI 43-101 exceeds that within the JORC Code, primarily by stipulating that certain geological parameters of the mineral reserve must be presented within a report, published in full, and presented in a particular way.
