Province / Territory:  Newfoundland & Labrador
Funding Source:  Federal (1983); Federal and Provincial (1993)
Year of Collection:  1982

The original regional lake survey for southwestern Labrador (Parts of NTS 22P, 23A and 23B) was conducted during the summer of 1982.

This report presents analytical and statistical data for gold and 25 other elements obtained by re-analyzing lake sediments from 1 406 sites, collected at an average density of one sample per 13.6 km². Original analytical data selected from Open File 902 (published 1983) for 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 under the auspices of the Canada - Newfoundland Cooperative Mineral Program (1982-1984).

The reanalysis program was 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.

M.McCurdy edited open files and coordinated production.

H. Gross and S.W. Adcock provided computer processing support.

C.C. Durham, S.J. Day, S. Carberry and R. Balma provided technical assistance.
