The reconnaissance surveys were undertaken 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.

The provincial funding was financed through the Canada - Newfoundland Development Subsidiary Agreement (1976 - 1982). This agreement was sponsored by the Departments of Regional Economic Expansion and Energy, Mines and Resources and the Province of Newfoundland.

Fisheries and Environment Canada provided funds for the determination of mercury.

E.H.W. Hornbrook directed the Geological Survey of Canada activities.

N.G. Lund was responsible for data management and open file production.

F. Williams of the Cartographic Section supervised map preparation.

Direct photo-head plotting facilities were made available by the map production directorate, surveys and mapping branch, E.M.R.

Provincial liason was with P.H. Davenport and B.A. Greene, Department of Mines and Energy, Newfoundland.
