The Alaska Resource Data File or "ARDF" was developed in the 1990's as a searchable collection of information about mines, mineral prospects, and occurrences throughout Alaska for metallic and some non-metallic resources. The information included in the database was gathered from published reports as well as unpublished information from industry, the U.S. Geological Survey, the Bureau of Mines (no longer in operation), the Bureau of Land Management, and other government and private sources. For each site or entry in the database a description of the geologic setting, workings and exploration, production (if any), reserves and other relevant information is provided.

The information collected in this database is fundamental to many types of minerals-related research and land-use issues. The USGS uses the ARDF to conduct mineral resource assessment studies and mineral deposit research. It is also used by the public, in particular the minerals industry, as one of the guides for mineral exploration.


The Alaska Resource Data File website presents multiple ways to access published reports and data relating to mines, prospects, and mineral occurrences in Alaska. Quadrangles can be selected from either a map or a table. Reports for each quadrangle including a bibliography are downloadable in various digital formats including, FileMaker Pro, and comma-separated-value (.csv). Alternatively the data for the entire state is available as a single download. Users may also access the data via the Mineral Resources On-Line Spatial Data website for use with Google Earth.

The initial stage of compiling data and database construction is complete, but periodic updates to information and the addition of entries are made on a regular basis. The latest update was made available in June 2016.
