This aeromagnetic survey was carried out by Novatem Inc. from February 23, 2019 to April 2, 2019. The data were recorded using split-beam cesium vapour magnetometers mounted in the tail booms of two Piper Navajo aircraft. The nominal traverse and control line spacings were 400 m and 2400 m, and the aircraft flew at a nominal terrain clearance of 150 m. Traverse lines were oriented N45°E with orthogonal control lines.

This map of the residual total magnetic field was derived from data acquired during an aeromagnetic survey carried out by Goldak Airborne Surveys during the period May 16, 2009 to July 1, 2009. The data were recorded using a split-beam cesium vapour magnetometer mounted in the tail boom of a Piper Navajo aircraft. The nominal traverse and control line spacings were 400 m and 2400 m, respectively, and the aircraft flew at a nominal terrain clearance of 150 m.

Reprocessing of magnetic data for Yukon was performed between November 2016 and March 2017. Aeromagnetic data were compiled, data of different resolutions were merged, and a series of images individually levelled for each map sheet were produced. For each 250k-scale map, the following magnetic derivative maps were produced: 1. Residual Total Magnetic Field; 2. Reduced-to-Pole Magnetic Field (RTP); 3. First Vertical Derivative of the Reduced-to-Pole Magnetic Field (RTP_VD); and 4. Tilt Derivative of the Reduced-to-Pole Magnetic Field (RTP_TDR). These maps are provided as pdfs, geotiffs and Geosoft grid files. Colour ramps/legends are provided for each map.

This aeromagnetic survey was carried out by Geo Data Solutions GDS Inc. from January 12, 2018 to March 16, 2018. The data were recorded using split-beam cesium vapour magnetometers mounted in the tail booms of a Beechcraft King Air and a Piper Navajo. The nominal traverse and control line spacings were 400 m and 2400 m, and the aircraft flew at a nominal terrain clearance of 150 m. Travers lines were oriented N45°E with orthogonal control lines.

This aeromagnetic survey was carried out by Goldak Airborne Surveys from February 17, 2014 to March 21, 2014. The data were collected using split-beam cesium vapour magnetometers mounted in each of the tail booms of 2 Piper Navajo aircraft. Nominal traverse and control line spacings were 400 and 1400 m, and the nominal terrain clearance was 125 m.
