The regional lake survey for west central Labrador (parts of NTS 23I, 23J, 23O) was conducted during the summers of 1978 and 1982.
This report presents new data for gold and 25 other elements obtained by re-analyzing lake sediments from 1 553 sites, collected at an average density of one sample per 13 km². Original analytical data selected from Open Files 560 and 904 (published 1979 and 1983 respectively) for 16 elements in sediments, and uranium, fluoride, and pH values in concomitant waters are also included in this report.

The original reconnaissance surveys were managed by the Geological Survey of Canada in conjunction with the Newfoundland Department of Mines and Energy under the Canada - Newfoundland Agreement on a Uranium Reconnaissance Program (1976-1982) and the Canada - Newfoundland Cooperative Mineral Program (1982-1984).
The reanalysis program was undertaken under theCanada-Newfoundland Mineral Development Agreement (1984-1989).
