The Stewart Subdistrict comprises mines that were developed along the Stewart and Barnett Fault Zones. The Stewart Fault Zone is a series of parallel high-angle normal faults that strike N25°–30°E. The fault zone is about three-fourths of a mile wide along its northern limits and widens to nearly 1.5 miles to the south, where the eastern segment aligns with a bend in the Ohio River. The northern extent of this fault zone cannot be accurately traced north of the community of Eichorn, but it may merge into the Hobbs Creek Fault Zone to the north. The Stewart Fault is the eastern fault, and most of the mines have been dug along this fault. However, to the south at the Barnett and Parkinson Mines, the mineralization seems to be better developed along the western Barnett Fault Zone.
