Open File 2475
Previous OF publication(s): 0560, 0903
Province / Territory: Newfoundland & Labrador
Funding Source: Federal and Provincial (1979 and 1993); Federal (1983)
Year of Collection: 1978
# Lake sites: 1724
# Stream sites: 0
Survey Area: 23360 km²
NTS Sheet(s): 023H, 023G
The regional lake survey for western Labrador (NTS 23H and part of 23G) 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 1724 sites, collected at an average density of one sample per 13.6 km². Original analytical data selected from Open File 560 (published 1979) and Open File 903 (published 1983) for 13 or 15 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 and under the terms of 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 the Canada - Newfoundland Cooperation Agreement on Mineral Development (1990-1994).
