Field station locations and magnetic susceptibility data collected in 2022 for the Mount Harper project, Eagle, Big Delta, and Mount Hayes quadrangles, Alaska
Description
Field station locations and magnetic susceptibility data collected in 2022 for the Mount Harper project, Eagle, Big Delta, and Mount Hayes quadrangles, Alaska, Raw Data File 2023-6, provides locations, field descriptions of rocks, and magnetic susceptibility measurements from rock outcrops and/or hand samples throughout the Mt. Harper project area. During the 2022 field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted 1:100,000-scale bedrock geologic mapping of ~2,600 mi2 (~6,700 km2) within the Eagle, Big Delta, and Mount Hayes quadrangles. The field area for the Mount Harper project covers an area from 50-60 miles northwest of Delta Junction, Alaska, and extends eastward into the Eagle Quadrangle 40-50 miles west of Chicken, Alaska. The project area is of current and historical interest for potential mineral resource development, including quartz vein gold (Au) mineralization, placer Au deposits, granite-hosted tin mineralization, and intrusion-related porphyry copper (Cu)-Au deposits. Mineral sites in and around the Mount Harper project area include Healy, the Pogo gold mine, Lucky 13, Eagle, and others.
