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

Survey Type:  Regional Lake Survey

The regional lake survey for eastern Labrador (parts of NTS 13I, 13J,13K, 13N and 13O) was conducted during the summers of 1977, 1978 and 1983.

This report presents revised data for gold and 25 other elements obtained by re-analyzing lake sediments collected at an average density of one sample per 13 km². Original analytical data selected from Open Files 513, 558 and 997 for up to 16 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) and Canada - Newfoundland Cooperative Mineral Program (1984 - 1989).

Analyses of remaining archive samples were undertaken under the Canada - Newfoundland Mineral Development Agreement (1984 - 1989).

E.H.W. Hornbrook directed the survey and archived analysis program.
