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 ...
The Bureau's Minerals Information functions were transferred to the U.S. Geological Survey (USGS) in early 1996. The "Mineral Industry Surveys", "Mineral Commodity Summaries", and the "Minerals Yearbook" continued to be published.
