Cosa Reports Anomalous Uranium in Sandstone at Darby Joint Venture with Denison Mines
Cosa Resources reported anomalous uranium intercepts at the Darby project, a joint venture where Denison Mines holds a 30% working interest. Drilling at the Charlie trend intersected weak basement mineralization of 0.04% U3O8 over 0.5 metres and strongly anomalous sandstone content over broad intervals. The results significantly upgraded the geological potential of three trends at the property, with the Gamma trend revealing a 100-metre-wide graphitic corridor and favorable unconformity relief. Assays are pending for additional holes, and Cosa plans to resume drilling in June following work at Murphy Lake North.
