A former lode Cu-Ag occurrence/mine located in the NE¼ sec. 3 and the NW¼ sec. 2, T26S, R29E, MDM, 0.8 km (0.5 mile) SSE of Woody, N of Howling Gulch. Production years 1890 - 1900 , 1918. MRDS database accuracy for this location is not stated. Idle since 1918.
Mineralization is hosted in granodiorite. The ore body is lenticular in form with a depth-to-top of 18.29 meters. The area is underlain by biotite-hornblende granodiorite which contains inconspicuous quartz veins and narrow aplite dikes. Both aplite dikes and veins are cut and displaced along mineralized shears. A sheeted zone is parallel to joint systems in the granodiorite. There are 6 veins. The principal Cu vein is 5 feet wide, strikes N5E and dips vertically. It appears that an ore shoot was formed at the intersection of the 5 foot vein and the sheeted zone that is 6 feet wide, strikes N70E and dips variably 42-60NW, based on near-surface evidence. Limonite gossan 16 inches (40 cm) thick occurs along the hanging wall of the sheeted zone. Both walls of the 5 foot vein are marked by slickensided surfaces with spare (sparce ?) mineralization extending into the wall rock. Massive sulfide ore on the dump is primarily composed of chalcopyrite with minor pyrite cut by veinlets of sooty chalcocite. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).
Workings include surface and underground openings with an overall depth of 73.15 meters and comprised of a 200 foot, single-compartment, inclined shaft with levels driven NW at 95, 135 and 185 feet of depth. 250 feet N of the inclined shaft, 2 vertical shafts were sunk on the continuation of the same (?) vein. One shaft is 240 feet deep with levels at 100, 140 & 200 feet. A 200 foot winze was sunk from the 200 foot level into the main ore shoot at an inclination of 45 degrees. Other workings include 5 small prospect pits and a caved adit.
Production data are found in: Troxel and Morton (1962).
Production statistics: Year: 1900 (period = 1890-1900): ore (accurate): ^19.4% (19 weight percent) Cu, 5.7 ounces 443 grams) Ag/metric ton.
Mill ore ranged from 2 to 8% Cu, and 2 ounces Ag/ton.
