NGR surveys were originally conducted in the Glenlyon map area in 1988. Stream sediment and water samples were collected from a total of 1378 sample sites. A total of 1096 original samples were selected for reanalysis. Representative 2 gram splits were successfully recovered from 1095 samples. Samples were analysed by an ultra-trace aqua-regia digestion ICP-MS package for 53 elements.

A stream sediment and water survey was carried out in the Coal River area of southeastern Yukon during the summer of 2005. This survey was carried out under a Joint Research Agreement between the Yukon Government (Oil & Gas and Mineral Resources Division of the Department of Energy, Mines and Resources) and the Federal Government, acting through the Earth Science Sector's Metals in the Environment Program. Analytical data accompany this document for 50 elements in stream sediments and 60 variables in waters from a total of 174 sites sampled in 2005. National Geochemical Reconnaissance protocol was used for the collection, preparation and analysis of waters and silts. Samples were collected in the Yukon Territory portion of NTS map sheet 95E, west of the height of land that marks the boundary between Yukon and Northwest Territories and separates the Coal River and Flat River drainage basins.

This product contains stream sediment geochemical data from regional geochemical surveys (RGS) in Yukon.

NGR surveys were originally conducted in the Dawson map area in 1976 and 1977. Stream sediment and water samples were collected from a total of 1738 sample sites. A total of 1129 original samples were selected for reanalysis. Representative 2 gram splits were successfully recovered from 1091 samples. Samples were analysed by an ultra-trace aqua-regia digestion ICP-MS package for 53 elements.

NGR surveys were originally conducted in the McQuesten map area in 1987 and 1988. Stream sediment and water samples were collected from a total of 841 sample sites. A total of 841 original samples were selected for reanalysis. Representative 2 gram splits were successfully recovered from 840 samples. Samples were analysed by an ultra-trace aqua-regia digestion ICP-MS package for 53 elements.

Geochemical Assessment Report Data Extracted database (GARDEd) includes geochemical data from assessment reports (ARs), describing over 350,000 surficial samples. Data are mostly from assessment reports in the Dawson Range submitted since 2005. Samples described in the database belong to one of four categories: rock, soil, stream sediments (referred to in GARDEd as silt), and vegetation. The initial release contains approximately 10% of the geochemical data in Yukon ARs.
