In 2013, the Corporation in collaboration with Cameco Corporation (Cameco), QFIR, and Environmental BioTechnologies Inc. (EBT), completed a multi-faceted surface geochemical sampling program over the Centennial uranium deposit (Centennial Survey), located on the Virgin River structural trend within the south-central portion of the Athabasca Basin, Saskatchewan. The Centennial deposit is a high-grade unconformity-type uranium deposit occurring at a depth of approximately 800 m that is currently in the drill-developed stage by Cameco and its joint venture partners, AREVA Resources Canada Inc. (AREVA) and Formation Metals Inc. (Coronation Mines).
The Centennial Survey was an applied research study that capitalized on our cumulative knowledge obtained from previous surface studies, including the Cigar West Study and other surface geochemical surveys conducted over five (5) of Uravan's active exploration projects. The objective of this survey is to advance our remote sensing geochemical technology by (a) determining if we can identify unique geochemical and isotopic signatures in the surface environment (soils and trees) that support element migration from a high-grade uranium deposit at depths >800m; and (b) investigating if these elements and isotopic signatures can be characterized as distinct, deposit-sourced geochemical signals or derived from the natural geochemical variations related to surficial geology and/or environmental effects.
The survey was completed in June 2013 and managed by Uravan’s technical group. The combined anomalous surface geochemical signals obtained from the various surface media analyzed (tree-cores, clay-sized fractions of soils, and MET samples) have clearly defined the surface projection of the Centennial uranium deposit, which occurs at depths greater than 800 m. The spatial relationship and surface distribution of certain pathfinder elements, lead (Pb) isotopic ratios (207Pb/206Pb), and MET microbial values in the media analyzed, provide a compelling, coincident surface anomaly that, when displayed with other known geophysical survey data and interpreted structural patterns, would certainly vector drilling to a deposit at 800 meters depth in a ‘green-fields’ exploration setting.
