A former Pb-Zn-Ag-Cu-Au-Hg-Sb mine located in sec. 20, T24S, R58E, MDM, 5.8 km (3.6 miles) WNW of Goodsprings, E of Shenandoah Peak, on private land within a Bureau of Land Management administered area. Discovered in 1892. Owned by J. F. Kent. Owned by the Security 1st National Bank and F. Nay and N. Meehan, California. Operated by the Yellow Pine Mine, Nevada (1964). Operated during the period 1906 to 1928. MRDS database stated accuracy for this location is 10 meters. The Prairie Flower and Yellow Pine Mines are now connected underground and are operated as one mine.
Mineralization is a polymetallic replacement deposit (Mineral occurrence model information: Model code 72; USGS model code 19a; Deposit model name: Polymetallic replacement; Mark3 model number 47), hosted in the Monte Cristo (Yellow Pine) (Bullion) Limestone. The ore bodies are breccia-filled and pipelike, and tabular replacement in form, strike NE and dip NW at a thickness of 15.24 meters. a width of 91.44 meters, and a length of 609.6 meters. The primary mode of origin was hydrothermal activity. The primary ore control was faulting and the secondary was fracturing and bedding planes. Wallrock alteration is moderate (dolomitization and silicification). The Yellow Pine Limestone is a member of the Mississippian Monte Cristo Formation. Hydrozincite is the most abundant zinc mineral. There is also some stibnite and cinnabar present. Local rocks include limestone and sparse dolomite, siltstone, and sandstone.
Regional geologic structures include regional normal faults, which are numerous and have attitudes which vary greatly, plus a thrust fault. Locally, there is a fault zone.
Workings include underground openings with an overall depth of 213.36 meters. Surprisingly, no further data regarding workings are provided in the MRDS files.
Analytical data results: Crude Pb ore contained 47-63% Pb, 5-13% Zn, and 17 to 22 opunces Ag/ton. Mixed Pb-Zn ore contained 13-16% Pb 27-30% Zn and about 11 ounces Ag/ton. Crude Zn ore contained 34-45% Zn, 3.5-6.5% Pb, and 1 to 6 ounces Ag/ton. The insoluble matter (mostly silica) composed 5-15% of the bulk.

66 - 145 Ma
|Felsic phaneritic intrusive rocks|
Age: Cretaceous (66 - 145 Ma)
Description: Granodiorite, granite, and related rocks make up the largest group of granitic intrusions exposed in Nevada. They are present in every county, and are especially abundant in west-central Nevada in an arcuate belt along the border with California extending north and eastward towards Idaho.
