Magnetic and radiometric data were collected with a helicopter between June 4 and 17, 2024, by EON Geosciences Inc. The survey contains a single block covering 1,975 km2, which includes an infill block with tighter line spacing located in the northcentral portion of the block. A total of 6,459 line-kilometers were collected. The magnetometer was installed inside the stinger attached to the helicopter nose. The airborne gamma-ray spectrometer was mounted on the interior floor of the helicopter cabin. The block was flown with a line spacing of 400 m and the northcentral infill block was flown with 200 m spacing. Tie-lines for magnetic leveling were flown at 1,600 m spacing.
