A former W mine located in sec. 21, T7S, R30E (MDM), 3/6 km (2.2 miles) W of Scheelite and 2.5 km (1.5 miles) S of Broken Finger Peak (coordinates of record), (E side of small lake on West Fork Gable Creek), E of Lower Morgan Lake, on National Forest wilderness land (John Muir Wilderness). MRDS database stated accuracy for this location is 10 meters.

Mineralization is hosted in limestone, hornfels, and granite. The ore body is lenticular in form, strikes N10W and dips 80W at a width of 15.24 meters and a length of 38.1 meters. The ore zone within the tactite averages 12 feet in width. Local rocks include Carboniferous marine rocks, unit 7 (Bishop) and/or pre-Cenozoic metasedimentary and metavolcanic rocks undivided.

Workings include surface and underground openings comprised of a 15 foot deep shaft and an open cut 20 feet long, 12 fet wide and 8 feet deep on the oputcrop, and a 20 foot adit, 100 feet below the outcrop.

Production data can be found in Norman and Stewart.

production information: Total production was less than 100 tons of ore, of which 59 tons averaged 5% WO3 and 30 tons averaged 2½% WO3.
