In 2022, the Arizona Historical Society’s Library and Archives acquired a selection of records from the Arizona Department of Mines and Mineral Resources (ADMMR). Our archivists are actively working on inventorying the materials, and will post updated inventories here as they are completed. These materials are available to view by appointment at our Tucson location.

If you have questions, or would like to schedule an appointment to view these collections, please email [email protected]. To learn more about these collections, check out the recording of our Digging Deeper program.
