Previous OF publication(s):  1354, 2691
Province / Territory:  Newfoundland & Labrador
Funding Source:  Federal and Provincial
Year of Collection:  1986

Survey Type:  Regional Lake & Stream Survey
# Lake sites:  1244
# Stream sites:  
Survey Area:  12634 km²
NTS Sheet(s):  014M, 014L, 024I, 024P, 025A

The regional lake and stream survey for northern Labrador (NTS 14M and parts of 14L, 24I, 24P and 25A) was conducted during the summer of 1986 .

This report presents analytical and statistical data for gold and 25 other elements obtained by re-analyzing lake sediments from 1244 sites, collected at an average density of one sample per 10.2 km². Original analytical data selected from Open File 1354 (published 1987) for 20 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 managed by the Geological Survey of Canada in conjunction with the Newfoundland Department of Mines and Energy.

The survey was undertaken under the auspices of the Canada - Newfoundland Mineral Development Program (1984-1989) and the reanalysis program was 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 provided computer processing support.

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

Other information:

The data presented for the southern portion of the area is a combination of lake and stream sediment and water surveys .

Whereas the northern part of the survey area is simply a regional stream sediment and water survey.
