This project describes the analysis and processing applied to the Nechako Basin 2-D data set. The processing is aimed at better defining the regional structure of the Nechako basin, which is largely covered by volcanic rock of variable thickness. The processing is based on a joint inversion technique using different geophysical domain such as seismic, […]

Magnetotelluric (MT) data collected in the Nechako Basin during 2007 have previously been inverted to produce 2D conductivity sections along seven profiles through the region. In the work reported here, these conductivity sections were used to assess the ability of z-axis tipper electromagnetic (ZTEM) data to determine and resolve the conductivity structure of the Nechako […]

This project was a 15 month study that combines an expert project team and a wide range of techniques to determine and assess the distribution, nature and thickness of Eocene volcanic rocks, and to evaluate the regional Eocene structural regime in the southern Nechako basin of south‐central British Columbia. This project compiles and integrates a […]

Geochemistry is an essential tool in mineral exploration. Research in the development of techniques and the understanding of geochemical processes and resultant exploration applications in Canada has lagged behind other parts of the world, particularly Australia. The purpose of this project and these results was to provide the mineral-exploration community with easy access to surficial […]

QUEST-South applies the QUEST and QUEST-West Project approach to British Columbia’s southern interior. The project created new geoscience information over an area of 130,000 square kilometers from Williams Lake to the USA border, and aid mineral exploration companies in their quest to make new discoveries. QUEST-South includes a new airborne gravity survey which covers 45,000 […]

Geoscience BC’s QUEST project was designed to stimulate mineral exploration in the Quesnellia Terrane of British Columbia. During 2007, about 2100 new lake and stream sediment samples were collected, and almost 5000 older drainage sediment pulps were re-analyzed, to improve the geochemical data base in the project area. One of the programs initiated by QUEST […]

Update April 2019: This information in this report has been superseded by Geoscience BC’s Earth Science Viewer online mapping tool, where you can view geochemical and other data.  Earth Science Viewer Geoscience BC has invested considerable time, effort and money in providing mineral exploration groups with a wealth of new geoscience data in the central […]

CSIRO Exploration & Mining has used a Self-Organizing Map approach to analyze a database of stream and lake sediment geochemical analytical results compiled and collected as part of the Geoscience BC’s QUEST Project. The study’s objective was to use CSIRO’s implementation of the Self-Organizing Map (SiroSOM) to identify patterns and establish relationships amongst the various […]
