Survey Description
During July and August, 2008, a helicopter-supported regional stream sediment and water survey was carried out in the Mount Eduni map area of west-central Northwest Territories. The survey covered approximately 16,000 km2 and 1,263 sites were sampled. The data are published in Geological Survey of Canada Open File 6312/NWT Open Report 2009-004.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
Sampling Procedure
NGR stream sediment and water
At each site a pre-labelled Kraft paper bag was two-thirds filled with silt or fine sand collected from the active stream channel. In practice, the silt sample was collected after water samples were collected but before a bulk sediment sample. Handfuls of silt from various points in the active stream channel were collected while gradually moving upstream. A moss mat sample was sometimes collected when a suitable sample was scarce or absent.
At every site, waters were sampled mid-channel, from flowing water where possible. At sites where sediments were taken for heavy mineral concentration (approximately every second site) two water samples were generally collected. Samples were collected in 125 mL Nalgene bottles. The bottles were rinsed two or three times before collecting the sample.
