In 2021, ASL completed a project for the Greenland Ministry of Mineral Resources (MMR) to process and analyze a large amount of airborne hyperspectral data over Gardar Province in south Greenland. The airborne data was collected over the Ilímaussaq intrusion and Igaliku Igneous Complex. The survey area is known to be rich in rare earths, but also contains underexplored segments of interest to mineral prospectors.
ASL generated mineral maps for high priority areas which in turn are to be used to support revision of geological knowledge and geoscience information for the mineral exploration industry.
Project services included:

• Radiometric calibration of survey lines to surface reflectance using field spectra
• Quality assessment of dataset (artifacts, atmospheric effects, geometric accuracy)
• Hyperspectral mineral mapping of high priority areas of the Gardar Province, identified by MMR as being rich in rare earth elements.
