A former surface and underground Au-Cu mine located about 1½ miles North of Cherry at 5,400 feet of altitude. Started in 1907 and closed in 1910. Owned by the Verde Inspiration Co.
Mineralization is a 4 foot wide vein (at the shaft), averaging 18 inches (45 cm) wide, striking N.35ºE. and dips 45ºW with ore in lenses and pods. Comprised of sheared granite with bunches of quartz. There appears to be 3 veins on the property. Ore control was faulting and shearing. Ore concentration was oxidation at near surface. No alteration noted. An associated rock unit is the Cherry Creek Quartz Diorite (informal).
Workings include a 400 foot incline at 35º with 375 feet of drift on one vein. A stamp mill and cyanide plant were erected on the site.
3 valid minerals.

1600 - 2500 Ma
Age: Proterozoic (1600 - 2500 Ma)
Description: Medium- to medium-coarse-grained hornblende-biotite diorite to granodiorite containing phenocrysts of hornblende (Anderson and Creasey, 1967). Includes tonalite of Cherry (DeWitt, 1989), and part of Cherry batholith (Anderson, 1989a). Newly named herein for exposures near Cherry. Type area is designated where main mass exposed from north of Cherry to far southeastern part of map area. Smaller bodies exposed along east side of Lonesome Valley. Prominent north-trending zone of high magnetic intensity along eastern Lonesome Valley probably marks western contact of Cherry Tonalite with metavolcanic rocks (Langenheim and others, 2002). Most mafic along western margin of main mass and in southern Lonesome Valley. Exposed in erosional highs beneath Tertiary basalt from Interstate 17 to southern margin of map area. Cuts Bishop Spring Granodiorite (unit Xbp) northwest of Rugged Mesa. Cuts Bland Tonalite (newly named, unit Xbl) east of Perry Mesa and south of map area, along Squaw Creek. Undeformed in most outcrops, but mildly to strongly flow foliated in places. Strongly deformed along Shylock fault and Shylock high-strain zone in southwestern Black Hills. Hosts gold-bearing quartz veins in Cherry district that are genetically related to the tonalite (Clements, 1991). Chemically is calc-alkalic, sodic to very sodic, and very Mg rich to Fe rich. Age of sample from near Cherry, from U-Pb zircon analyses, is 1,740 Ma (Anderson and others, 1971). K-Ar hornblende dates of 1,694 and 1,690 Ma obtained from samples near Cherry (Lanphere, 1968; Dalrymple and Lanphere, 1971). 40Ar/39Ar total fusion date of 1,709 Ma obtained from one hornblende (Dalrymple and Lanphere, 1971). K-Ar biotite dates of 1,689–1,693 Ma also obtained from same samples. Conflicting age (cuts 1,720-Ma Bland Tonalite but has U-Pb zircon age of 1,740 Ma) may be due to more than one tonalite body within a composite pluton (Anderson, 1989a)

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
