A former underground Ag-Cu-Au-Pb-Zn mine located on 19 claims (9 patented & 10 unpatented), 2 miles SSW of Crown King at 6,100 feet of altitude. Reopened 1910 and closed 1911. Owned by the Yavapai Consolidated Gold-Silver-Copper Co. Discovered by Mr. D.C. Moreland. Claims extend into the W½NE¼ and the E½SW¼ of sec. 27, and the E½NW¼ and the E½SW¼NW¼ of sec. 34; and, the SWSENE of sec. 22.
Mineralization is a vein deposit. The principal vein outcrops boldly about 100 feet below the shaft collar in a small gulch. It is here a composite quartz lode 20 feet wide with a body of quartz 4 feet thick on the hanging wall. The strike ranges from N.10ºE. to N.15ºW. and dips 60º to 70ºW. Ore several feet wide consists almost exclusively of white quartz, in places rather dense and flinty. Ore control was faulting and shearing. Ore concentration was oxidation of near surface ores. No alteration noted.
Local rock is the Crown King Granodiorite (informal name) which is in contact with Yavapai Schist a short distance south of the mine. Also present are rhyolite dikes.
Area features include veins that trend N20-25E, parallel to the foliation in Precambrian metamorphic rocks.
Workings feature a 3-compartment, 300 foot deep shaft, plus a shaft at least 100 feet deep (1881). Later, a vertical shaft 750 feet deep with several levels with drifts several hundred feet long on each side of the shaft. A 10-stamp mill and roaster was erected. Production was an estimated $750,000, mostly silver (period values).
8 valid minerals.

66 - 100.5 Ma
Age: Late Cretaceous (66 - 100.5 Ma)
Description: Stocks at Copper Basin, Walker, Poland Junction, and Crown King, and dikes throughout Bradshaw Mountains. Smaller stock at Pine Flat, south of Big Bug Mesa. Areally moderate-size gravity lows of about 6 mGal associated with Poland Junction and Walter stocks (Langenheim and others, 2002, fig. 8). East-west zone of low magnetic intensity corresponds with outcrop of Poland Junction stock (U.S. Geological Survey, 1972). Northeast-southwest zone of high magnetic intensity associated with Walker stock (U.S. Geological Survey, 1972). Possible buried stock suggested by boulders of granodiorite in sedimentary rocks at base of Hickey Formation along Verde fault, east of Cherry. Stock would extend to the south, toward Interstate 17. An areally moderate-size gravity low extending across Interstate 17 may support the interpretation of a buried stock (Langenheim and others, 2002, fig. 8), but also could be caused by an underlying, low-density Early Proterozoic stock. Aeromagnetic data are equivocal (Langenheim and others, 2002, fig. 5b). Texture and mineralogy of igneous rocks from one stock to another are very similar. Groundmass of fine-grained quartz, feldspar, and biotite containing phenocrysts of biotite and hornblende. Ranges in composition from calc-alkalic monzodiorite to calc-alkalic granodiorite and averages alkali-calcic to calc-alkalic tonalite. Average tonalite is metaluminous to mildly peraluminous, very sodic to sodic, and Mg rich to average in Fe/Mg ratio. K-Ar biotite and hornblende dates of Copper Basin stock are 73 Ma (Christman, 1978). K-Ar hornblende date of Walker stock is 64 Ma. K-Ar biotite date of Poland Junction stock is 70 Ma. K-Ar biotite date of Crown King stock is 65 Ma. Extensive hydrothermal alteration, veining, and mineralization associated with most stocks. Base- and precious-metal vein deposits spatially associated with most stocks (Keith and others, 1984; Welty and others, 1985; Welty and others, 1989). Breccias localized along rhyolite dikes and margin of stock at Crown King (Ball, 1983; Ball and Closs, 1983). Gold-rich breccia pipes localized in stock at Copper Basin (Johnston and Lowell, 1961). Silver-rich veins localized along granodiorite porphyry dikes and in stock at Poland Junction (Sturdevant, 1975). Zonation of base- and precious-metals common at Walker and Poland Junction stocks (O’Hara and others, 1991)
