Regional Stream Sediment and Water Geochemical Data Golden, Brazeau Lake, Canoe River and Mount Robson, Southeast BC (NTS 82N, 83C, 83D, 83E)
- Chris Naas, CME Managing Consultants

Geochemical Survey Area A stream sediment and water survey within map sheets 82N, 83C, 83D and 83E completes the coverage within the southeastern portion of the province. The program will report analytical data for an estimated 1,353 sites from approximately 19,600 square kilometers. Sample coverage does not include areas that lie within a local, regional, provincial or federal park.

Survey analysis on sediments include 37 elements by ICP-MS, 35 elements by Neutron Activation, Fluorine and LOI. Water analysis includes pH, conductivity and Fluorine. Field observations regarding sample media, sample site and local terrain were recorded during the collection process.

In order to monitor the integrity of the geochemical database and to provide a measure of precision, accuracy and confidence, a quality control program was implemented for all samples.

Geoscience BC Report 2006-5/ MEMPR Geofile 2006-12 reports results of regional geochemical drainage sediment - water surveys in the Golden (NTS 82N), Brazeau River (83C), Canoe River (83D) and Mount Robson (83E) map sheets. This digital release consists of reports in PDF format, and appendices in a ZIP format file.

Most of the known base and precious metal occurrences are in the Golden map sheet although much of the remaining survey area has a higher potential for metallic and industrial mineral deposits. During 2005 stream sediment and water samples were collected from 1409 sites covering 21 560 square kilometres in southeastern BC. The samples were analysed for trace and minor elements by instrumental neutron activation and by aqua regia digestion - inductively coupled plasma mass spectrometry (ICP/MS), for loss on ignition (LOI) and for fluorine. Water samples were analysed for pH, conductivity and fluoride. Gold values up to 357 ppb and silver up to 1747 ppb were detected in sediment samples from the surveys.
