This project is part of the State of Alaska's Airborne Geophysical/Geological Mineral Inventory (AGGMI) program, a special multi-year investment by the state to expand Alaska's geologic and mineral resources knowledge base, catalyze future private-sector mineral exploration and development, and guide state planning. AGGMI was funded by the Alaska State Legislature and managed by the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys. Geologic mapping in the northern Fairbanks mining district was funded in part by the U.S. Geological Survey National Cooperative Geologic Mapping Program under STATEMAP award number 07HQAG0076, 2007 (fieldwork), and G20AC00367, 2020 (GeMS conversion). Additional funding was provided by the State of Alaska General Fund.

The northern Fairbanks mining district map area lies within the Yukon-Tanana Uplands in rocks that we interpret to correlate with the Cambrian to Late Proterozoic Fairbanks schist and the Wickersham Grit unit. These rocks are intruded by several phases of plutonism, of which two occur in the map area: Tertiary and Cretaceous plugs, dikes, and sills with differing characteristic geochemical signatures. The Cretaceous intrusions are regionally associated with placer- and lode-gold mines and occurrences. The age data in this report, when combined with other regional DZ data, will help to build a more robust detrital zircon record in the Yukon-Tanana Uplands.
