The Arizona Geological Survey (AZGS) has a new website for mining data. This is a culmination of consolidation of the now defunct Arizona Department of Mines and Mineral Resources (ADMMR) with the AZGS.
Over the past several years, AZGS has performed a comprehensive inventory of the 30 archival collections, creating finding aids for the more than 10,000 folders, 6,000 maps, and 7,000 photographs.

On July 2, 2014, the James Doyle Sell collection, which include more than 800 Arizona mine file records, was added to the Arizona Geological Survey Mine Site. The Sell mining collection comprises over 1,800 folders containing geologic reports and mineral exploration data from around the world, but primarily from Arizona and other states in the Southwest.
James (Jim) Sell was a native Arizonan, born in Casa Grande in 1930; he passed away on 18 Feb. 2011. For 32 years, Jim worked for ASARCO, where he served for some years as Southwest Exploration Manager. During his long career, Jim engaged in 100s of exploration and mining projects. A meticulous fellow, Jim kept records of most of these endeavors and donated his entire collection to the Arizona Dept. of Mines and Minerals Resources (ADMMR).
