Till sampling survey, NTS 92L/12, northern Vancouver Island, British Columbia, 1991.  


British Columbia Ministry of Energy and Mines, Energy and Minerals Division, Geological Survey Branch

Survey Description

183 till samples were collected in the Quatsino area on northern Vancouver Island, British Columbia. In addition, an orientation survey was carried out near the Island Copper Mine during the regional sampling program. The orientation survey covered an area extending 8 km down ice (west) of the deposit. Samples from the orientation survey collected in map sheet 92L/12 were incorporated into the regional data set presented here. The data are published in British Columbia Geological Survey Open File 1992-21.

Data Description: Paper report; report can be downloaded.

Quantities Analysed: 0.250-0.125 mm (after pulverization), 0.125-0.63 mm, and <0.063 mm fractions by INAA for 27 elements and by ICP-AES after aqua regia for 29 elements.

Geochem Plots Available: Proportional symbol map show dispersal of elements.

Project History

1991-1992 Quatsino, south central British Columbia drift exploration project, 1991.
  The Quatsino project is part of the British Columbia Geological Survey’s Drift Prospecting Program. This project evaluates drift sampling as a regional mineral exploration tool. It is designed to demonstrate the applicability of combined surficial geology-exploration geochemical methods in the search for drift-covered mineral deposits in areas of glaciate terrain. The data are published in British Columbia Geological Survey Open File 1992-21.
