St. John’s, Newfoundland, November, 2023

The Makkovik River West airborne survey covers parts of six 1:100 000 scale map areas. For each map area, the survey results are presented as 10 thematic maps – 2 maps from the magnetic data and 8 maps from the radiometric data. This release consists of sixty full-coloured maps in pdf format.
