Summary

This open file contains the results of a pilot study utilizing WorldView-3 satellite data to evaluate the alteration mineralogy of a portion of the Long Harbour Group, within the Avalon Zone (NTS map areas 1M/10 and 11) of Newfoundland, which is, locally, host to both high- and low-sulphidation-style epithermal mineralization. The contract report related to the acquisition and interpretation of the satellite data, in addition to 177 ground-based follow-up short wavelength infrared (SWIR) spectral measurements, collected utilizing a TerraSpec® Halo spectrometer, are included within this database. Whole-rock geochemical results for 28 samples collected from select alteration zones highlighted by the satellite study are also included.
