Barbara B – Lower Kittanning Seam. Barbara B property is in Somerset County, Pennsylvania, within the USGS Berlin 7.5- Minute quadrangle. Barbara B, an underground mine which operated in the Lower Kittanning seam, is permitted but has been closed. The former leased property has been relinquished yet the owned coal resource remains; however, the face up area has been backfilled. Since the leased property has been dropped, there is no longer direct access to the remaining controlled coal and therefore this mineral property has been excluded from resource estimates. Average seam thickness is 4.6 feet. |
