Open File 0520
Previous OF publication(s): 0418
Province / Territory: Yukon Territory
Funding Source: Federal (1976 & 1977)
Year of Collection: 1977
# Lake sites: 0
# Stream sites: 1738
Survey Area: 23890 km²
NTS Sheet(s): 116B, 116C, 116F, 116G
The regional stream survey for Central Yukon (NTS 116B, C, F and G) was conducted during the summers of 1976 and 1977.
Open File 520 contains previously reported data from the 1976 surveys as well as new data from the Keno Hill area, sampled in 1964. This report presents analytical and statistical data for 13 elements in stream sediments from 1,738 sample sites, collected at an average density of one sample per 13.8 km². Uranium, fluoride, and pH values in waters from these sites are included in this report.

Samples were collected in 1976 (reported in OF 418) and 1977.
Sediments collected in 1977 (Open File 520) were analyzed for Hg in addition to 12 other elements.
Stokes Exploration Management Co., Vancouver, BC provided a cook and subcontracted from Viking Helicopters Ltd. for helicopter services in 1977.
