AbstractAs a result of the 1973 international energy crisis, the Canadian government introduced the Federal-Provincial Uranium Reconnaissance (URP) Program in 1974. The objectives of this program included establishing and maintaining high-quality databases of fi eld observations and geochemical data for stream and lake sediments and waters, and airborne gamma-ray survey data, to aid uranium exploration. Technological advances in analytical methods and computing since then have led to improvements in effi ciency, presentation, and the amount of information derived from each site. Counterbalancing these improvements have been steady decreases in funding and staff. Large-scale regional surveys managed by the Geological Survey of Canada (GSC) and carried out by contractors as stand-alone projects for mineral exploration, ceased in 2004. Since then, regional geochemical surveys have been undertaken within larger projects with multiple objectives including environmental evaluation and surfi cial and bedrock mapping, in addition to supporting mineral exploration.
Summary(Plain Language Summary, not published)
Regional geochemical surveys managed by the Geological Survey of Canada and carried out by contractors as stand-alone projects for mineral exploration have become smaller, more focussed activities within larger projects with multiple objectives. Technological advances have led to improvements in efficiency, presentation and the amount of information derived from regional geochemical surveys.
