Wheeler River is the largest undeveloped high grade uranium project in northern Saskatchewan. According to the 2016 preliminary economic assessment, The Phoenix and Gryphon deposits have indicated resources of 166,400 tonnes at an average grade of 19.14% uranium oxide containing 70.2 million lb. of U3O8. The inferred resource is 842,000 tonnes averaging 2.37% U3O8.­­­­ The Phoenix deposit will be mined by jet boring, and the Gryphon by longhole stoping. The project has an estimated pre-production capex requirement of $560 million.
