Summary(Plain Language Summary, not published)
Currently, all of Canada's uranium production comes from the Athabasca Basin. One of the premier recent discoveries is termed the Phoenix deposit, in which high-grade ore is bound by two regional fault systems. This study is the first to outline the geochemical and mineralogical alteration patterns associated with the deposit and is examining the potential for significant remobilization of 'pathfinder elements' along these reactivated faults. While a suite of pathfinder elements has been identified in past studies, analytical advances leading to lower detection limits and acquisition of a regional dataset establishing background values permit refinement to the current state of knowledge. The goal is to characterize any subtle mineralogical, geochemical and isotopic signatures that could facilitate deep exploration and link these to a parallel study examining similar expressions in surficial media.
