The original regional lake survey for southwestern Labrador (Parts of NTS 22P, 23A and 23B) was conducted during the summer of 1982.
This report presents analytical and statistical data for gold and 25 other elements obtained by re-analyzing lake sediments from 1 406 sites, collected at an average density of one sample per 13.6 km². Original analytical data selected from Open File 902 (published 1983) for 15 elements plus loss-on-ignition in sediments, and uranium, fluoride, and pH values in concomitant waters are also included in this report.
