Survey Description

Helicopter-supported sample collection was carried out during the summer of 1997 in the Mesilinka River map area, British Columbia.  A total of 1068 stream sediment and 1055 stream water samples were collected from 1008 sites.  Average sample site density was 1 site per 13 km2 throughout the 13,000 km2 survey area.  Field duplicate samples were routinely collected in each analytical block of twenty samples.  The data are published in British Columbia Regional Geochemical Survey RGS 47.

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

Sampling Procedure

Primary and secondary drainage basins with catchment areas of less than 10 km2 were sampled.  Sediment samples weighing 1 to 2 kg were obtained from the active stream channel.  Samples were primarily fine-grained material mixed with varying amounts of coarse sand, gravel and organic material.  Surface water samples were collected in 250 mL bottles and suspended solids were excluded where possible.
