Located due west of the United Verde orebody on the opposite (western) side of the gabbro. Acquired from the Jerome Mines Development Co. by the Haynes Copper Co. in 1904. Later successively owned by the Monarch Copper Co., Jerome Victor Extension Copper Co., and the West United Verde Copper Co. In October, 1919, the West United Verde Copper Co. deeded the claim to the United Verde Extension Co. A decision was made to explore the ground under the Haynes shaft and this was done by means of a drift driven on the 3000 level of the United Verde Mine. This drift was started July, 1930, and reached the Haynes massive sulfide pipe in June, 1931.
The Haynes pipe is a steeply-plunging body of massive sulfide and quartz that is relatively small in cross section compared with the length along the axis. It extends from a short distance above the 2700 level downward to an undetermined point between the 3450 and 3700 levels of the United Verde Mine. On the 3000 level the pipe is triangular shaped with each leg at about 120 feet long. The cross sectional area seems to diminish upward and downward from there. With depth the sulfide pipe elongates parallel to the gabbro contact. The bearing of the axis and the plunge vary.
Shaft sunk to 700 feet between 1907 and 1911; subsequently deepened to 1,200 feet, with about 1,700 feet of drifts and crosscuts on the 700 level and 700 feet on the 1200 level.

|Cenozoic volcanic rocks|
Age: Pliocene (2.588 - 5.333 Ma)

1600 - 2500 Ma
|Tuffaceous metasedimentary rocks|
Age: Proterozoic (1600 - 2500 Ma)
Description: Fine-grained felsic to intermediate-composition tuff and interbedded metasedimentary rocks. Numerous exposures in zones 2–6; particularly abundant in zone 4 where referred to as part of Spud Mountain Formation (Anderson and Blacet, 1972a) and in zone 6 as part of Grapevine Gulch Formation (Anderson and Creasey, 1967). Thickness difficult to estimate because of variable intensity of folding. South of Slate Creek in zone 2, unit contains much tuff of dacitic composition and discontinuous beds of iron-formation. Tuff extends past west edge of map into Zonia mine area, where it is interbedded with felsic to intermediate-composition flows. West of Lynx Creek in zone 3A, unit is a mixture of andesitic to rhyolitic tuff and minor chemically precipitated metasedimentary rocks. Along and south of Chaparral high-strain zone, from Spud Mountain on the north to past Big Bug Mesa on the south, in zone 4A, dacitic tuff is interbedded with minor andesitic tuff. Farther south, west of Battle Flat, this tuff is present on the side of dacite crystal tuff (unit Xd2). Southeast of Iron King mine, and extending between Big Bug Mesa and Little Mesa, in zone 4A, dacitic to rhyodacitic tuff contains minor andesitic material. On west side of southern part of Brady Butte Granodiorite in zone 4A, dacitic to rhyodacitic tuff is interbedded with minor sedimentary rocks. South of Crown King to Silver Mountain in zone 4C, tuff contains much sedimentary material and thin beds of iron-formation and chert. A large exposure of tuff extends from east of Humboldt on the north to east of Mayer on the south (zones 4C and 5B). Predominantly volcanic in the north, the tuff contains an increasing percentage of wacke material to the south. Apparently, tuff grades into wacke (unit Xw) southeast of Blue Bell mine. Much of Grapevine Gulch Formation in southwestern Black Hills (zone 6A) is fine-grained siliceous sedimentary rocks and tuff. Fine-grained siliceous tuff is exposed along east side of Lonesome Valley
Comments: Early Proterozoic plutonic rocks are widely exposed throughout map area. In order to aid in the discussion of these rocks, the exposures of plutonic and metavolcanic rocks are divided into six zones (zones 1–6, from west to east). These zones are roughly parallel to regional foliation and contain rock units that are similar to one another. The zones are not crustal blocks nor are they necessarily separated from one another by discrete tectonic structures

1600 - 1800 Ma
|Early Proterozoic granitic rocks|
Age: Statherian (1600 - 1800 Ma)
Description: Wide variety of granitic rocks, including granite, granodiorite, tonalite, quartz diorite, diorite, and gabbro. These rocks commonly are characterized by steep, northeast-striking foliation. (1600-1800 Ma)
Comments: ~ 1.6 - 1.8 Ga
