AbstractThis report summarizes the key activities completed under the uranium ore systems project of the Targeted Geoscience Initiative Four (TGI-4) program operated by the Geological Survey of Canada. This collaborative project between government, academia and industry examined unconformity-related uranium systems in the Proterozoic Athabasca (Phoenix, Millennium and McArthur River deposits and Dufferin Lake zone), Thelon (Bong deposit) and Otish (Camie River deposit) basins in order to refine genetic models and exploration techniques for the deposits. Significant to the Canadian economy, high-grade unconformity-related uranium deposits remain prime exploration targets given their potential for large tonnage, high-grade ore. As the depths of discoveries increase in the established Athabasca Basin and geological settings hosting the ore diversify, a variety of new exploration methods are required to allow for efficient target identification and successful discovery of deeply buried ore deposits. The results of the project clearly illustrate that deeply buried ore, ore-forming fluids, structural-fluid controls and precipitation mechanisms produce diagnostic signatures that can be identified and modelled over the entire fluid pathway through fertile fault systems, including post-mineralization dispersal of elements into subsurface and surficial environments.
