Minerals Availability and Industry Locator System Files (MAS / MILS)

MAS / MILS also provided for the systematic storage, timely update, and rapid retrieval of comprehensive information on mining operations, mineral deposits / occurrences and processing plants throughout the world. This series consists of data from two inter-related minerals data systems, the Minerals Availability System (MAS) and Minerals Industry Locator System (MILS).

The MAS files contain data on worldwide known mining operations, mineral deposits / occurrences and processing plants. There are as many as 12 inter-related MAS data files for each geographic area: states, the District of Columbia, and foreign areas. The available data files, or "tables", are: Bibliography (BIB Table, reference material relating to the mineral property); Comments (CMT Table, evaluator's comments or remarks relating to the mineral property); Commodity (CMO Table; identifies the numerous products that can be recovered from a mineral deposit); Geometry (GEO Table; identifies the formation characteristics, overall shape, and relative dimensions of the ore body); History of Production (HP Table; historical production figures in tons); History of Exploration (HX Table; includes data on the method of exploration, year of work, and year of information); Lithology (LIT Table; used to describe when and how mineralization occurred among the rock formations associated with the deposit); Lithology - Rock (ROC Table; provides a description of individual rock types that comprise the lithology of this mineral formation); Minerals (MIN Table; describes the mineralogy of the deposit including geologic age, name, and grain size); Name (NAM Table; contains all of the alternate or secondary names associated with the mineral property); Ownership (OWN Table; owner / operator identification information); and Resources (RES Table; contains published resource information relating to the mineral deposit ).
