Geophysics - Program Information

Geophysical survey areas

The Airborne Geophysical/Geological Mineral Inventory (AGGMI) program is a multi-year investment to expand the knowledge base of Alaska's mineral resources and catalyze private-sector mineral development. Products resulting from airborne geophysical surveys generally include: 1:63,360-scale aeromagnetic and airborne electromagnetic maps, 1:63,360-scale geologic maps; and various other geological, geochemical, and geophysical data compilations.

Questions relating the geophysics program or to geophysics publications should be directed to: Laurel Burns

Request for proposals: Tanacross region

DGGS, in partnership with the U.S. Geological Survey (USGS), is soliciting proposals for collecting fixed-wing airborne magnetic data in the Tanacross region of Alaska. The survey area includes parts of the Tanacross and Eagle 1:250,000-scale quadrangles, and encompasses parts of the Goodpaster and Fortymile mining districts. The area has gold and copper-gold-molybdenum prospects and significant potential for new discoveries. Additionally, there is very active exploration and several newly-identified gold and copper-gold-molybdenum resources immediately east of the Alaska border in Yukon Territory, Canada. Resulting data will be processed into a variety of maps and digital files, which will be published on the DGGS website. The Request for Proposals (RFP) can be found on the State's Online Public Notice site.
