QUEST-South: Catchment Basin Analysis and Stream Sediment Exploration (NTS 82E, 82L, 82M, 92H, 92I, 92J, 92O, 92P)
- Dennis Arne and Britt Bluemel, ioGlobal Solutions Inc.
This project is designed to add value to Regional Geochemistry Survey (RGS) data from the QUEST-South project based on an analysis of catchment size and levelling of the data for catchment bedrock geology. Data levelling will be based on exploratory data analysis (EDA) and ground proofing of the results against known mineral deposits and occurrences using an approach that is methodologically proven. In this respect the project represents an enhancement of the geochemical atlas provided by Lett et al. (2008), rather than a duplication of this work, as it seeks to identify true geochemically anomalous catchments within the data set by levelling the data for the effects of sediment dilution in catchments of variable size. An expert interpretation of the RGS geochemistry data will generate new validated exploration targets, and thus stimulate exploration using an existing dataset that has cost both the Federal Government and the Province of British Columbia a considerable amount of effort to obtain. In addition, catchment analysis will allow an assessment of the adequacy of the existing RGS data coverage for future in-fill and follow-up surveys.
Although the methodology proposed is well established and documented, it is beyond the capacity of most small to mid-tier exploration companies to undertake as it requires a competent level of geochemical expertise to process the data effectively. This project will provide all companies exploring in the QUEST-South project area with access to a high level interpretation of the RGS data done by the largest global consultancy group of applied geochemists. The products provided will be of immediate use to industry, and will be made available in a variety of formats to facilitate this (pdf maps, geoTIFF gridded images, GIS shape files and a spreadsheet of levelled and regressed data).
