Summary(Plain Language Summary, not published)
Currently, all of Canada's uranium production comes from the Athabasca Basin. The McArthur River and nearby Millennium deposits are spatially associated with a regional fault system termed the P2 structure. At McArthur River, high-grade mineralization is bound by the regional P2 and the local VQ fault systems. The spatial relationship implies that the structures played a role in focusing ore-forming fluids during creation of the deposit. This study aims to build on that hypothesis by documenting subtle mineralogical, geochemical and isotopic changes in the fault systems as they approach the deposit.
