A former W occurrence/mine located in secs. 27 &34, T18S, R29E, MDM, 1.6 km (1.0 mile) SE of Grouse Peak (coordinates of record), on National Forest monument land (Sequoia National Monument). Operated 1949-1955. MRDS database stated accuracy for this location is 10 meters.
Mineralization is hosted in limestone. The limetone is massively bedded, strikes N10 to 35W, dips 22 to 30S, and is in contact with a medium-grained hornblende-biotite granodiorite. Slivers of fine-grained schistose hornblende-quartz diorite are found at places along the sheared contact. A small, completely silicated, metamorphic body lies just N of the limestone pendant. This body is roughly divided longitudinally into 2 mineralogical assemblages with a garnet-epidote tactite on the NE side and diopside-wollastonite rock on the SW side. Associated rocks include diorite. 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 comprised of 2 exploratory adits, 1 crosscut access adit, 2 glory holes, an open cut, and stopes from the upper workings connected by raises.
