Ref::www.wma-minelife.com/uranium/papers/karnes.htm; Cherepon, Alan J., Minerals of the Karnes Uranium District - The Franklin of Texas; Smith, A.E. (1991), Texas Mineral Locations Index, Rocks & Min.: 66(3). This district is located about 45 miles South of San Antonio. The uranium deposits of this district are overlain by tuffaceous sandstone. Mineralization occurs within the uranium ore bodies and within concretions in the overlying sediments. Virtually all, if not all, of the open pit mines are now reclaimed.

Both sides of Farm Road 791 east from county line to Falls City.
