NTS 92F - Alberni / RGS 25 / GSC OF 2183 / GBC R2011-4

The Alberni (NTS 92F) reconnaissance-scale stream sediment and water survey was completed in 1989 and the resulting field and analytical data were released in 1990. A total of 962 sediment and 863 water samples were collected from 908 sample sites. Moss-mat sediment and stream water samples were collected from 806 sites on Vancouver Island. Stream sediment and water samples were collected from 102 sites on the mainland.


Geoscience BC Report 2011-4 contains results of the 2010 Vancouver Island Reanalysis project plus previously published data for gold, fluorine and loss on ignition in stream sediments and fluoride, uranium and pH in stream waters. This information has been provided in a variety of digital formats. PDF files include survey descriptions and details regarding methods, field and analytical data listings, summary statistics, sample location map, geology map and maps for individual metals. Raw digital data of original field and analytical information plus new reanalysis results are included in Excel (XLS) format.

The 1989 survey was conducted by the British Columbia Ministry of Energy, Mines and Petroleum Resources (MEMPR). Funding was supplied in part by the Canada-British Columbia Mineral Development Agreement (1985 - 1990).


Program activities were managed by P.F. Matysek, J.L. Gravel and W. Jackaman. Contracts were let to the following companies for sample collection, preparation and analysis.
