The reconnaissance surveys were undertaken by the Geological Survey of Canada in conjunction with the Department of Indian Affairs and Northern Development and the Government of Yukon under the Canada-Yukon Mineral Development Agreement (1985-1989).

E.H.W. Hornbrook directed the survey.

P.W.B. Friske coordinated the operational activities of contract and Geological Survey of Canada staff.
