A Systematic Approach To The Appraisal Of National Mineral Supply

A comprehensive knowledge of the availability of mineral resources to evaluate and assure a dependable supply is a prerequisite in establishing and maintaining a viable national economy. Since no nation is self-sufficient in all its mineral needs, its prosperity depends to a great degree upon its developing and maintaining an effective national minerals policy. This must be preceded by a systematic inventory of mineral resources that may be available to that nation. The U.S. Bureau of Mines is implementing a mineral deposit inventory program of domestic and foreign mineral occurrences, with initial emphasis on the domestic. In order to provide an in-depth appraisal of minerals availability, the approach includes not only realistic estimates of quantity and quality, but other essential factors such as costs, technology, environmental constraints, and development-time requirements. Analysis of this information provides usable relationships of quantity, price, time, and associated degrees of confidence of the occurrence of identifiable mineral resources. Keeping pace with a changing minerals industry and handling the large volume of information required in this undertaking demands that computer methods be employed.
