“…Similar reconnaissance in Alaska (White, 1952;Wedow, 1954) revealed several Precambrian and Paleozoic black shales containing 0.001 to 0.003 percent uranium, but only the phosphatic black shale near the base of the Calico Bluff formation of Mississippian age was found to contain more, generally between 0.003 and 0.006 percent uranium.…”

In 1948, White (1952a conducted a brief reconnaissance for radioactive deposits during which he found traces of uraniferous minerals, one of which was tentatively identified as clarkeite, in stream-concentrate and bedrock samples from a tributary of the Rapid River (6, fig. 38) and from Sunaghun Creek (7, fig.…”
