A former underground Au-Ag-Pb-Zn-Cu mine located on the West side of Turkey Creek, about 15 miles from Mayer at 3,000 feet of altitude. Discovered 1900 by Theising. Reopened 1933 and owned by H.C. Mitchell & Associates (1934). Produced 1923-1949.
Mineralization is a vein deposit a few inches to more than 1 foot wide with a tabular ore body hosted in the Spud Mountain Volcanics. In places, a branching lode several feet wide. Ore control was faulting and shearing. Ore concentration was oxidation at near surface.
Precambrian schist strikes Northward and dips almost vertically. The vein strikes NE-ward and ranges in dip from 30º to less than 10º SE. It occupies a fissure zone, proably the result of thrust-faulting. Vein filling consists of a very coarsely-crystalline, milky to clear, glassy quartz with rather abundant, irregular masses and disseminations of sulfides. Vein walls are intensely sericitized and silicified, and in places, contain disseminated metacrysts of practically barren pyrite. The oxidized zone extended to the 250 level on the incline.
Area structures include low-angle (less than 40 degrees) veins that cut across foliation. Foliation and transposed bedding in metavolcanic rocks trends N-S.
Workings include a 100 foot deep shaft; later a 500 foot deep inclined shaft and approximately 2,000 feet of workings.

1600 - 2500 Ma
|Rhyolitic flows and pyroclastic rocks|
Age: Proterozoic (1600 - 2500 Ma)
Description: Fine-grained, porphyritic rhyolite containing phenocrysts of quartz and minor feldspar. Includes small bodies of breccia and tuff, as well as silicified and veined rhyolite that is not included in the hydrothermally altered rhyolite related to massive sulfide mineralization (unit Xrh). Some flows have extensively brecciated flow tops and margins, and are difficult to distinguish from bodies of breccia. Exposed throughout zones 1 through 6. Particularly abundant in zone 5A along eastern margin of Crazy Basin Granite and in zone 6B in southern Black Hills. Flows and minor tuff east of Climax mine in zone 2 are interbedded with dacite and more mafic rocks. Bodies north of Spruce Mountain in zone 3A are mostly flows, but include some hypabyssal intrusive masses that cut basaltic andesite. Limited data suggest that flows and hypabyssal bodies are calc-alkalic rhyolite to rhyodacite that is mildly peraluminous, very sodic, and Mg rich. Thin flows and minor bodies of tuff north of Chaparral high-strain zone and near Lynx Creek in zone 3A range from calcic rhyolite to rhyodacite that is strongly peraluminous, very sodic, and very Mg rich to alkali-calcic rhyolite that is mildly peraluminous, very sodic, and Fe rich (Vance, 1989; this study). South of Chaparral high-strain zone, along Big Bug Creek, in zone 4B, bodies of rhyolite are interbedded with rhyodacite and minor tuff. Least altered bodies of rhyolite range in composition from calcic rhyodacite to alkali-calcic rhyolite that is mildly peraluminous, ranges widely in K/Na ratio, and is average to Fe rich (Vance, 1989). North of Big Bug Creek, near Mt. Elliott, limited data suggest presence of alkali-calcic rhyolite to alkali rhyolite that is mildly peraluminous, average in K/Na ratio, and Fe rich. Large bodies of rhyolite, breccia, and tuff are exposed from north of Crown King stock to southeast of Humboldt in zone 4C. The largest bodies, near DeSoto mine and southeast of Round Hill, are silicified. Limited data from smaller bodies north and west of Mayer suggest rhyolite is alkali-calcic, mildly peraluminous, sodic, and average in Fe/Mg ratio. Largest concentration of rhyolite flows, tuffs, and variably silicified rhyolite in map area is along Black Canyon and within the Black Canyon high-strain zone, from near Cordes to past southern boundary of map area (Jerome, 1956; Anderson and Blacet, 1972c). Silicification and loss of alkali metals make original composition of rhyolites difficult to ascertain. Bodies of rhyolite near Cordes in zone 5A are fine-grained flows interbedded with andesite and basaltic andesite. Rhyolite is calc-alkalic, mildly peraluminous, very sodic, and average to Fe rich. Numerous bodies of rhyolite from southeast of Round Hill to west of Yarber Wash in zone 5B range from flows to hypabyssal intrusive masses. Data are too limited to assess the chemistry of these rhyolite bodies. Fine-grained to aphanitic flows and hypabyssal bodies are interbedded with tuff west of northern Black Hills, along Coyote Wash (zone 6A). Limited data suggest that high-silica rhyolite is calc-alkalic, mildly peraluminous, very sodic, and Fe rich. Porphyritic rhyolite containing quartz and minor plagioclase phenocrysts at Willow Spring, east of Dugas in zone 6A, is alkali-calcic, mildly peraluminous, very sodic, and average to very Fe rich. The Buzzard Rhyolite in southern Black Hills (zone 6B) is a flow-banded rock that contains phenocrysts of plagioclase and quartz. Fragments of felsic volcanics are common in rhyolite, and breccia beds that lack matrix material are noted (Anderson and Creasey, 1958). This high-silica rhyolite ranges from calcic to alkali-calcic and is mildly to strongly peraluminous, very sodic, and Mg rich to Fe rich. Cleopatra Formation (previously referred to as Cleopatra Quartz Porphyry) and Deception Rhyolite at Jerome are suggested to be as old as 1.76 Ga (Anderson and others, 1971). Newer determination of 1,738±0.5 Ma (S.A. Bowring, supplementary data in Slack and others, 2007) is preferred age of rhyolite
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

|Early Proterozoic metavolcanic rocks|
Age: Statherian (1600 - 1800 Ma)
Description: Weakly to strongly metamorphosed volcanic rocks. Protoliths include basalt, andesite, dacite, and rhyolite deposited as lava or tuff, related sedimentary rock, and shallow intrusive rock. These rocks, widely exposed in several belts in central Arizona, include metavolcanic rocks in the Yavapai and Tonto Basin supergroups. (1650 to 1800 Ma)
