A former Cu-Ag-gypsum-Au occurrence/mine located in the E½E½ sec. 34, T13N, R24E, MDM, 0.9 km (0.6 mile) SSE of Ludwig (site) (3.5 miles E of Artesia Lake; 1 mile SW of the Ludwig Mine), on private land. Operated prior to 1914 and during the period 1916 to 1919. MRDS database stated accuracy for this location is 10 meters.
Mineralization is a Cu deposit (Mineral occurrence model information: Model code: 59; USGS model code: 18b; Deposit model name: Skarn Cu; Mark3 model number: 8), hosted in quartz monzonite porphyry and limestone. The ore body is a lenticular, large skarn body that dips 70NW. The major structural control is a N50 shear zone with a width of 45.72 meters and a length of 121.92 meters. The ore occurs at the contact between garnetized meta-sediments and limestone that has been intruded by granodiorite and monzonite. Controls for ore emplacement included a shear zone. This deposit is in a fringe position relative to the andradite-chalcopyrite skarns with many similar characteristics to the Mason Valley Mine (https://www.mindat.org/loc-15785.html). Secondary enrichment includes chalcocite, covellite, chrysocolla and copper carbonates. Associated rocks include Yerington Batholith volcanic rock (rhyolite). Local alteration includes albitic, sericitic, propylitic, and weak potassic, Local rocks include alluvial deposits.
Regional geologic structures include the Yerington Batholith. Local structures include a fault trending N50E and dipping 70NW.
Detailed geologic and alteration maps of the Casting Copper Mine, along with a good summary bibliography for the skarns in the Yerington district, can be found in Einaudi (2000).
Workings include surface and underground openings with an overall depth of 106.68 meters and comprised of a glory hole and a shaft down to 350-foot level. A railroad bed passes right through the dumps.
Production statistics: Year/period: up until 1914: ^5 weight percent Cu.
29,000 tons of ore were shipped prior to 1914; however, there are no details, with the major production between 1916 to 1919. Production was reported to total $4,265,942.00 (period values).
