Kuskowkim Kilbuck and Buckstock Mountains magnetic and radiometric geophysics
Project Details
Project ID:
1730
Nickname/Abbreviation:
Kuskokwim Kilbuk-Bucks GP
Parent Project:
Geophysics ProgramStatus:
Complete
Description:
The Kilbuck and Buckstock airborne magnetic and radiometric geophysical surveys cover parts of the Russian Mission, Sleetmute, Bethel, and Taylor Mountains quadrangles, 80-260 kilometers east of Bethel, Alaska. New Resolution Geophysics USA collected magnetic and radiometric data with a helicopter from May 20th to July 31st, 2025. A total of 49,565 line kilometers were collected, with 24,246 line kilometers collected in block A (Buckstock) and 25,319 line kilometers collected in block B (Kilbuck). In total, this survey covers 15,926 kmē in this region. NRG makes use of the Scintrex CS3 Cesium magnetometers in both the aircraft stinger and ground base stations. The radiometric crystals were located in the aircraft cabin; 33.6 liters of downward-facing and 8.4 liters of upward-facing crystals were used for this survey. The Kilbuck and Buckstock Mountains survey was flown with a line spacing of 400 meters (m) and a nominal ground clearance of 100 m. The data from this survey will improve the understanding of geology and mineral potential and promote resource exploration of the Kuskokwim River region.
