Previous OF publication(s): 1107
Province / Territory: British Columbia
Funding Source: Federal and Provincial (1984); Provincial (1985)

NTS Sheet(s): 093H
The regional stream sediment and water survey of the McBride, British Columbia map sheet (NTS 93H) was conducted during the summers of 1984 and 1985.
The east half of 93G and west half of 93H were sampled in 1984 and the data was released as Open File 1107 (published 1985). Additional sampling undertaken in 1985 covered the remaining portions of 93G and 93H.This report presents analytical and statistical data for up to 17 elements (V for 1984 samples only) in stream sediments from 1,119 sample sites, collected at an average density of one sample per 13.2 km². Loss-on-ignition in sediments (1984 only), and uranium, fluoride, and pH values in waters from these sites are included in this report.

The reconnaissance surveys were undertaken by the Geological Survey of Canada in conjunction with the British Columbia Ministry of Energy Mines and Petroleum Resources. The initial survey was under a "letter" of understanding for a cooperative project while the 1985 survey was under the auspices of the Canada - British Columbia Mineral Development Agreement (1985-1990).
W.M. Johnson directed the British Columbia Ministry of Energy Mines and Petroleum Resources activities (1984, 1985).

Additional sampling undertaken in 1985 to cover the remaining portion of 93H mapsheet.
Analysis was in 1984 and 1985 for all elements with the exception of V and LOI which were not done in 1985.
