USING REMOTE SENSING TO DELINEATE AU-PLACER DEPOSITS IN THE EAGLE A-2 QUADRANT, FORTYMILE RIVER DISTRICT, ALASKA


CURTIS, Daniel, Geology/Geography Department, Eastern Illinois University, 600 Lincoln Avenue, Charleston, IL 61920, BURNS, Diane M., Department of Geology/Geography, Eastern Illinois University, 600 Lincoln Avenue, Charleston, IL 61920 and VIERTEL, David C., Geology and Geography, Eastern Illinois University, 600 Lincoln Avenue, Charleston, IL 61920, drcurtis@eiu.edu

This study sought to explore the use of satellite remote sensing in detecting or verifying mineral deposits in remote areas, by adding Color/Infrared and Hyperspectral data to existing geological maps, to create a map that better defines the location of known gold placer deposits. This procedure might allow for better maps to be made before field teams are sent to remote or dangerous sites.

The Fortymile River district of Eastern Alaska has produced placer gold since the late 1900’s; the gold located within Tertiary gravel deposits within the banks of the river channel. This site was chosen due to its remote nature, and the known presence of a specific, detectable economic mineral close to the surface.

Mapping results are optimistic but incomplete, as processing of entire hyperspectral data set is unfinished at the time of submission.
