• Project ID:

  1730

• Nickname/Abbreviation:

  Kuskokwim Kilbuk-Bucks GP

• Parent Project:

  Geophysics Program

• Status:

  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 km² 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.
