| Deposit | Deposit consists of at least 67 separate workings (see Clardy and Bush, 1976) along a 26 mile long by 6 mi wide fault controled band mostly in Pike County. This area is in the Athens Plateau south of the Ouachita Mountain region. (Moved the location to be along this belt instead of 10 miles south of it.) |
