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.
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.

Mineral Resources are further sub-divided, in order of increasing geological confidence, into inferred, indicated and measured as categories. Inferred Mineral Resource is the part of a mineral resource for which quantity, grade (or quality) and mineral content can be estimated with a low level of confidence. It is inferred from geological ...

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 ...
It reviews the mineral and material industries of the United States and other countries. The Minerals Yearbook contains statistical production data as well as information on economic and technical trends. First published in 1933, it was preceded by The Mineral Resources of the United States. [1]
