Description:
The Arizona Department of Mines and Minerals operated from 1940 to 2011 to promote the development of Arizona's mineral resources through technical and educational processes. This collection consists of various reports, maps, records and related materials acquired by ADMMR regarding mining properties in Arizona. At times, property owners supplied information, ADMMR staff performed field visits or staff clipped articles from periodicals and publications. Each record's title refers to the primary name of a unique mineral locality. Alternate names of mines will be included in the fully cataloged records. Since the former index (the Arizona Mineral Industry Location System) included not only mineral localities for which the Department had a report, but included all mineral localities in Arizona, some files listed as "missing" may never have had a report.
