A former underground Pb-Cu-Ag-Zn-Au-Mo-Bi-perlite mine and group of 132 unpatented claims located in the NW¼ sec. 26, and the NE¼ sec. 27, T4S, R15E, about 1½ miles east of the 79 Mine, 3-4 miles NW of Hayden, on the NW side of Toronado Peak, ½ mile S of Chilito, on federal land. Discovered by Mr. Watson in 1880. Closed 1950. Claims extend into sec. 27. In 1913 the London-Arizona Consolidated Copper Co. merged London-Range, London-Arizona, and the O'Carroll & Ball shafts, and the Curtin (Humphrey) shaft, but some were later split. Other operators included the Toronado Gold Mining Co.; David Hartley; and J.W. Wright. Additional names that apply to this property: O'Carroll claims; Humphrey property; Reagen property; D.H. claims.

Mineralization is an irregular ore body hosted in Percha Shale and the Martin Formation. Ore control was the Chocolate fault and the base of the Martin Formation. Ore concentration was the oxidation process. An associated rock unit is rhyodacite.

The London-Arizona ore deposit probably represents the outer peripheral zone of a major ore body with the portions towards the main intrusive contact being eroded away.

Workings include a 180 foot deep shaft on London-Range; the 325 foot deep Curtin shaft; and some shallow shafts. Over 1500 feet of drifts, tunnels, and crosscuts. Production was some $1,050,000 between 1912 & 1928 (period values).

Serpukhovian - Early Cambrian
323.2 - 541 Ma
Mississippian, Devonian, and Cambrian sedimentary rocks

Age: Paleozoic (323.2 - 541 Ma)

Stratigraphic Name: Tapeats Sandstone; Bright Angel Shale; Muav Limestone; Temple Butte Formation; Redwall Limestone; Bolsa Quartzite; Abrigo Formation; Martin Formation; Escabrosa Limestone

Description: Brown to dark gray sandstone grades upward into green and gray shale, overlain by light to medium gray or tan limestone and dolostone. This unit includes the Tapeats Sandstone, Bright Angel Shale, Muav Limestone, Temple Butte Formation and Redwall Limestone in northern Arizona, and the Bolsa Quartzite, Abrigo Formation, Martin Formation, and Escabrosa Limestone in southern Arizona. These rocks record intermittent sea-level rise and inundation in early Paleozoic time. (330-540 Ma)

Lithology: Major:{sandstone,shale,limestone}, Minor:{dolostone,quartzite}
