Survey Description

Stream sediment and water samples were collected at 95 sites in 2003 in the Buffalo Head Hills area, northern Alberta

The data are published in GSC Open File 4735.  This publication also contains kimberlite indicator mineral data from heavy mineral concentrates.

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.

The geographic extent of the survey is defined by the following polygons:

  • Covers part of NTS 84G (Wadlin Lake) in the northern Buffalo Head Hills area, northern Alberta.  The Wabasca River cuts north-south through the western part of the study area.

  • Covers parts of NTS 84F (Bison Lake) and 84K (Mount Watt) in the northern Buffalo Head Hills area, northern Alberta.  It is located approximately 20 km south of the village of La Crête, AB.
