Survey Description


During the summer 2004, stream sediment and water samples were collected from 122 sites in northern and southwestern Buffalo Head Hills, northern Alberta.  The northern survey area lies south of the community of La Crete.  Access to sample sites was mainly by helicopter.  The southwestern survey area is located west of the community of Red Earth Creek.  Samples were collected by helicopter.  The data are published in Geological Survey of Canada Open File 5057.

This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.

Sampling Procedure

NGR stream sediment, water and HMC

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.

Material for heavy mineral concentrates was collected from the upstream points of mid-channel bars, at a single point where possible.  Material was wet-sieved through a 12-mesh stainless steel sieve into a 5-gallon plastic pail lined with a heavy-duty plastic bag until a sample weight of 10-15 kg was attained.
