A former underground Ag-Cu-Pb mine located on 14 claims in the SW¼ sec. 33, T3N, R16E, about 3.6 miles N of Chrome Butte. Unsurveyed, approximately 15 miles N of Globe. Discovered in 1876 by McMillan. Produced 1878-1947. Previous owners/operators include the McMillian Mining Co. (W.F. Holmes Jr, 1947); McMillian-Stonewall Mining Co. (1937); the Apache Mountain Development Co; the McMillan Silver Mining Co. (1881); and, Mr. William Langford (1947).

Additional names for this property include: Old Owen McMillan Mine; Little Mc Gen No. 97 Mine; Hannible MS 1209 claim; Stonewall Jackson Gen No. 95.

Mineralization includes a very large vein of chlorides and native silver with a 1 to 2 inch (2.5 to 5 cm) thick horizon of nearly pure native silver.

No detailed geologic map or detailed geologic description of this mine is available.

Workings include a 600 foot deep main shaft and over 700 feet of drifts (1881). There were at least two old shafts connected at the 170 foot and 440 foot levels, drifts on the 130 foot, 230 foot, and 360 foot levels. The main workings are on the Stonewall Jackson claim. A 5-stamp mill and steam hoist were installed on the property (before 1881). The dump was reworked in 1947 by J.A. Alexander. No appreciable production after 1916.
