• Project ID:

  1742

• Nickname/Abbreviation:

  Kuskokwim Ganes Creek MAG

• Parent Project:

  Geophysics Program

• Status:

  Complete

• Description:

  The Ganes Creek airborne magnetic and radiometric geophysical survey covers part of the Kuskokwim Mountains west of McGrath, Alaska. The survey area includes parts of the Ophir, Medfra, Iditarod, and McGrath quadrangles. EON Geosciences Inc collected magnetic and radiometric data with a Eurocopter AS350 B2 helicopter from June 21 to September 7, 2024, and a Eurocopter AS350 B3+ helicopter from June 16 to 25, 2025. A total of 25,731 line kilometers were collected, covering 8,197 km2. Magnetic data were collected with a Scintrex CS-3 cesium-vapour split-beam sensor. Radiometric data were collected with two Radiation Solutions RS-500 series multi-channel gamma-ray spectrometers, model RSX-5, with 512 channels, for a total crystal volume of 33.6 liters downward-looking and 8.4 liters upward-looking (for atmospheric radon detection).
