(requires an Internet connection)
Helicopter-supported sample collection was carried out from July to September 2005 in the Anahim Lake and Nechako River map areas in central British Columbia. A total of 2070 sediment and water samples were collected from 1957 sites at an average density of 1 site per 9.9 km 2 throughout the 19 500 km 2 survey area. Lake sediment and water samples were collected from 1855 sites in low lying areas in both map sheets. In the Anahim Lake map sheet, stream sediment was collected from 102 sites in areas of greater relief. Tweedsmuir and Itchallgachuz Provincial Parks were excluded from the sampling.
The data are published in British Columbia Ministry of Energy, Mines and Petroleum Resources GeoFile 2006-11/Geoscience BC Report 2006-4. Geoscience BC refers to the surveys in NTS 93C and 93F as Project 2005-47 and Project 2005-14 respectively.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
Lake sediments were collected with a torpedo style sampler. Lake water samples were collected approximately 15 cm below the lake surface before deploying the torpedo.

The geographic extent of the survey is defined by the following polygons:
Covers parts of NTS 93C (Anahim Lake), 93F (Nechako River), a very small area in the northern part of 92N (Mount Waddington), a very small area in the southern part of 93K (Fort Fraser) and a very small parts of the westernmost parts of 93B (Quesnel) and 93G (Prince George) in central British Columbia. It is bounded to the west by Tweedsmuir Provincial park. Itchallgachuz Provincial Park is found in the middle of 93C.
