DGGS Digital Data Series 18, Alaska Minerals Database, is a working, internal database that supports multiple data products developed by the Alaska Division of Geological & Geophysical Surveys (DGGS), including the Alaska Mineral Industry Report series (https://dggs.alaska.gov/pubs/minerals) and a web service of significant mineral industry occurrences and industry activity in 2020. DGGS anticipates developing additional products from the database in the future. This abstract and data dictionary will be updated as more of the database becomes publicly available over time. The full, unpublished database contains information about significant mineral occurrences in Alaska, including industry activity by year, mineral resource estimates, mine production statistics by year, and an interpreted mineral system type using the classification scheme of Hofstra and Kreiner (2020). The database also associates records in Alaska Resource Data File (ARDF; U.S. Geological Survey, 1996) with significant mineral occurrences, as interpreted by DGGS. DGGS annually compiles mineral industry information from past-year statements issued by companies, including press releases and corporate annual and financial reports, as well as phone interviews, replies to questionnaires, and news media articles. Only publicly available data compiled by DGGS are visible; confidential data are incorporated into statewide figures. The database is actively updated as new mineral activity data become available each year. Property information and previous years' data will be updated to resolve errors, reflect new geologic interpretations, and display newly available data. Consequently, products developed from the database may change over time as information and figures are updated. DGGS encourages members of the public to contact DGGS' Mineral Resources Section staff to discuss potential changes to the data or errors to be resolved in our derivative products. The data are available from the DGGS website: http://doi.org/10.14509/30873.
