Mineralization is the Stonewall vein and its junction with the Dime and Arizona veins (faults), hosted in Troy Quartzite and Martin Limestone. The ore zone strikes N68E and dips 55NW to vertical. The deposit lies in fault fissures in quartzite over a diabase sill. The ore occurs in both the diabase and the quartzite. The main fissure strikes N68E but intersecting fissures are also mineralized. The outcrop of the Stonewall fault is similar to that of the Buckeye vein, consisting mainly of quartz, specularite, cuprite, and copper carbonates and silicates. Mineralization was probably associated with an Early Tertiary, post-diabase intrusion period, although the nearest outcrop of Early Tertiary Schultze Granite is at the Old Dominion Mine to the W.
A substantial amount of ore has been extracted from shallow workings on the Stonewall fault near its junction with the Dime and Arizona faults.
Workings include a 2-compartment shaft 855 feet deep with cross cuts at the 500 foot levels, called the Clark and Faugh shafts. The developments total 91.44 meters in length and 260.6 meters in depth. Any production after 1921 was included in Old Dominion figures in ABGMT-USBM file data.
