Field station locations and magnetic susceptibility data for the Chena-Pogo and Mount Harper projects, Big Delta and Circle quadrangles, Alaska, collected June-September 2023
Description
Field station locations and magnetic susceptibility data for the Chena-Pogo and Mount Harper projects, Big Delta and Circle quadrangles, Alaska, collected June-September 2023, Raw Data File 2023-27, provides field station locations and magnetic susceptibility data for the Chena-Pogo and Mount Harper projects, Big Delta and Circle quadrangles, Alaska, collected June-September 2023, Raw Data File 2023-27, provides locations, field descriptions of rocks, and magnetic susceptibility measurements from rock outcrop and/or hand samples from the Mount Harper and the Chena-Pogo project areas. The field area for the Mount Harper project is north of Delta Junction and northeast of the Alaska Highway and extends southeast to 40-50 miles northwest of Tok. The Chena-Pogo project area is 0-200 miles south and east of Chena Hot Springs. During the 2023 field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted 1:100,000-scale bedrock geologic mapping of ~5,700 mi2 (~15,000 km2) within the Big Delta and Circle quadrangles, Alaska. The project areas are of current and historical interest for potential mineral resource development, including quartz vein gold (Au) systems, placer Au deposits, granite-hosted tin mineralization, and intrusion-related copper (Cu)-Au deposits. The Chena-Pogo and Mount Harper areas include the Pogo lode gold mine and the Healy, Lucky 13, Eagle, and many other prospects. The DGGS Mount Harper and Chena-Pogo projects aim to produce more accurate and integrated modern geologic maps and supporting datasets to promote mineral resource exploration in eastern Interior Alaska.
