DGGS Staff2022geodatabaseDigital Data SeriesDDS 18Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys2 p.https://doi.org/10.14509/30873DGGS 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 The full, unpublished database contains information about significant mineral occurrences in Alaska, including industry activity by year, mineral resource estimates, mine production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.This data supports multiple data products developed by Alaska Division of Geological & Geophysical Surveys (DGGS), including the Alaska Mineral Industry Report series (https://dggs.alaska.gov/pubs/minerals).

Data are merged with USGS ARDF records, assembled into a relational database, pertinent records are flagged for confidentiality, and the mineral system type is interpreted using the classification scheme of Hofstra and Kreiner (2020). DGGS symbolizes the non-confidential, publically available records to display in a statewide interactive map, which is accessible through the DGGS ArcGIS portal. This work is ongoing and expected to continue throughout the source data's useful lifespan.Hofstra, A.H. and Kreiner, D.C., 2020U.S. Geological Survey, 20182020pointGS_1984_Web_Mercator_Auxiliary_Sphere0000coordinate pair0.000000010.00000001metersD_WGS_1984WGS_19846378137.000000298.257223563mineral_prop_occurrenceMineral property information including name, commodities, and deposit type.DGGS, USGS, and publically available industry datamineral_prop_occurrencePropertyIDPrimary key; relates to tables mineral_activity, mineral_prod_stats, mineral_prop_resource, and mineral_prop_ardf_xrc.this reportint4PropertyName of property.this reportvarchar(255)Major CommoditiesMajor commodities roughly in order of economic significance.this reportvarchar(255)Critical MineralsCommon critical minerals from ARDF and public data sources; in alphabetical order.this reportvarchar(255)Commodity GroupCommodity group with which the property is associated.this reportvarchar(255)Deposit TypeDeposit type with which the property is associated.this reportvarchar(255)Public ResourceFlag for whether the property has public resource information; can be either modern or historical resource.this reportvarchar(10)Past ProducerFlag for whether the property has produced a resource; small production noted in ARDF may not be included.this reportvarchar(10)mineral_ activityMining activity year and property status.DGGS and publically available industry datamineral_ activityActivityIDPrimary key of mineral_activity table.this reportnumberPropertyIDForeign key to mineral_prop_occurrence table.this reportnumberMining YearMining year that the activity took place; generally equates to calendar year.this reportnumberProperty StatusStatus of the property during the mining year.
