Uranium in the Poison Basin area, Carbon County, Wyoming - a preliminary report

Uranium minerals were found on October 15, 1953, about seven miles west of Baggs in the Browns Park formation of the Poison Basin area, Carbon County, Wyo. The occurrences extend over an area of at least several square miles in secs. 4 and 5, T. 12 N., R. 92 W., and secs. 32 and 33, T. 13 N., R. 92 W. Uranophane-bearing sandstones contain as much as 3.21 percent uranium in select samples. The occurrences cannot be evaluated because their dimensions and average grade have not been determined. The presence of uranium, however, is significant because it indicates that uranium deposits may be present in the Browns Park formation and also in the underlying formations unconformably overlapped by the Browns Park.
