A former Cu occurrence/mine located in secs. 20 & 21, T24S, R58E, MDM, 5.1 km (3.2 miles) WNW of Goodsprings and E of Shenandoah Peak, on private land within a Bureau of Land Management administered area. MRDS database stated accuracy for this location is 10 meters.
Mineralization is hosted in Mississippian limestone. Controls for ore emplacement included a shear zone. The ore occurs along fractures in the shear zone. Ore minerals are associated with iron-stained chert lenses. Local rocks include limestone and minor amounts of dolomite and shale.
Local geologic structures include local shear zone probably associated with the NE extension of the Alice Fault.
Workings include underground openings with a length of 38.1 meters and an overall depth of 10.67 meters.
Production data are found in: Hewett (1931).
Production information: Produced 75 tons of ore averaging 15 to 20% Cu.

|Holocene - Pleistocene|

Age: Pleistocene (0 - 2.588 Ma)
Description: Unit is present in all counties. Some counties divided the alluvium into younger and older units, and some did not. For those that did not, or used other generalized terms for Quaternary rocks, the unit Qal has been used for the general undivided alluvium. Additionally, when polygons have been edited and changed to alluvium, Qal was used as the general value; hence it now is present in all counties. Qya-Younger alluvium: Map unit is used in Churchill, Elko, Esmeralda, Eureka, Humboldt, Lander, and Lincoln Counties where geologic information suggests better-defined younger versus older alluvium. It is mostly interchangeable with Qal, except that it implies some specifically younger Quaternary deposits.
