Survey Description


During the summer of 1979, fourteen areas (Anomalies 1 to 14) in Labrador were selected for detailed follow-up geochemical lake sediment and water sampling, and in three instances, airborne gamma ray surveying.  The areas were chosen from the coverage region of the 1978 Labrador Uranium Reconnaissance Program.  A total of 868 lake samples were collected at an average density of 1 sample per 3.2 km2.  Airborne gamma ray surveys were flown over all or portions of anomalies 9, 10 and 11 for a total of 890 line kilometres.

The data are published in Newfoundland and Labrador Department of Mines and Energy Open File LAB/0224 and are also part of a geochemical lake survey compilation, Open File LAB/1465.

Sampling Procedure

Sampling was carried out using a float equipped helicopter with a permanently mounted manual winch to raise the sampler from the lake bottom.
