NTS 104K - Tulsequah / BC RGS 20 / GBC R2012-5

The Tulsequah (NTS 104K) reconnaissance-scale stream sediment and water survey was completed in 1987 and the resulting field and analytical data were released in 1988. A total of 896 sediment and 880 water samples were collected from 847 sample sites.


Geoscience BC Report 2012-5 contains new ICP-MS analytical results generated by the QUEST-Northwest Project which have been provided in the Microsoft(r) Excel (XLS) file GBC REPORT 2012-05.XLS.

The 1987 survey was undertaken by the British Columbia Ministry of Energy, Mines and Petroleum Resources (MEMPR) in conjunction with the Geological Survey of Canada (GSC).  Funding was provided by the GSC under a "Letter of Understanding" for a co-operative project and by the Canada - British Columbia Mineral Development Agreement (1985 - 1989).


E.H.W. Hornbrook and P.W.B. Friske directed and coordinated the activities of the GSC staff. P.F. Matysek directed and coordinated the MEMPR activities. 

The following contracts for collection, sample preparation and analysis were supervised by the MEMPR staff.
