A former surface and underground Ag-Pb-Au-Cu-silica mine located in sec. 31, T9S, R5E, about 2 miles W of Tat Momoli (Jackrabbit) and about 4 miles directly N of Prieta Peak, on private land. Discovered in 1881. Produced 1881-1937. Previous owners and operators include John D. Walker; W.C. Smith and John Moran (1890); Casa Grande Copper and Gold Mining Co. (1892); Tuba City Mining and Milling Co. (1904); F. and Ramone Andrade (1935, 1937). Owned by the Tuba City Mining Co. (1961). Additional names which apply to this property: Agua Mine; Agwa Mine; Tuba City Co.; Sahuarro Mine; Keystone Mine; Casa Grande Cu and Au Mining Co., Agwa MS 2441 Patented claim; Tuba City Mining and Milling Co.; Sahuarro MS 2441 Patented claim; Keystone MS 2441 Patented claim; and Jack Rabbit silica.

Mineralization involves a NE-striking normal fault at a contact between limestone and porphyry. Ore is mostly in veins, some small replacement bodies. The host rock units are the Escabrosa Limestone and quartzite. Fault contact with andesite on the south (downthrust) side and limestone on the north (upthrown) side. The vein may continue N and S of the terminating faults. The limestone bedding has an ENE strike, 25NW dip.

Workings include 3 inclined shafts; 1 vertical shaft of 420 foot depth with stoping at 165 feet, coming off of the 3 inclined shafts. Extensive drifting and crosscutting at 250 feet, coming off of 1 of the inclined shafts. Underground workings are inaccessible. Production was $1 million produced in 1883 (period values); subsequently, a few sacks of high grade ore were produced to 1912. Quartzite was produced for copper smelter flux.
