The regional stream survey for southeastern Yukon (NTS 105G) was conducted during the summer of 1987.

This report presents analytical and statistical data for 20 elements in stream sediments from 913 sample sites, collected at an average density of one sample per 13 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.

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.

Other information:

Gold usually determined on 10-gram sample, allowing a detection limit of 1 ppb; sample weights less than 10 grams resulted in a detection limit of 2 ppb. Sample weights less that 5 grams not analyzed.
