The regional lake survey for eastern Labrador (NTS 13N) was conducted during the summer of 1978.
This report presents analytical and statistical data for gold and 25 other elements obtained by re-analyzing lake sediments from 764 sites, collected at an average density of one sample per 13.9 km². Original analytical data selected from Open File 558 (published 1979) for 13 elements plus loss-on-ignition in sediments, and uranium, fluoride, and pH values in concomitant waters are also included in this report.

The original reconnaissance surveys were carried out by the Geological Survey of Canada in conjunction with the Newfoundland Department of Mines and Energy under the terms of the Canada - Newfoundland Agreement on a Uranium Reconnaissance Program (1976-1982).
Open File 1636 (published 1989) included reanalysis data for part of NTS 13N and was funded under the Canada - Newfoundland Mineral Development Agreement (1984-1989).
Analyses of remaining archive samples were undertaken under the Canada - Newfoundland Cooperation Agreement on Mineral Development (1990-1994).
P.W.B. Friske coordinated the activities of contract and Geological Survey of Canada staff under the reanalysis program.
E.H.W. Hornbrook directed the original survey.
