Province / Territory: Newfoundland & Labrador
Funding Source: Federal and Provincial (1977 and 1992)
Year of Collection: 1977

The regional lake survey for eastern Labrador (NTS 13I West, 13J, 13O South) was conducted during the summer of 1977.
This report presents analytical and statistical data for gold and 25 other elements obtained by re-analyzing lake sediments from 865 sites, collected at an average density of one sample per 17.9 km². Original analytical data selected from Open File 513 (published 1978) 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 NTS 13O and parts of NTS 13I and 13J, 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).
