A former W-Mo-Cu-Au-Ag-Bi mine located in secs. 30 & 31, T6S, R30E, MDM, and in secs. 19 & 20, T6N, R31E, MDM, 4.1 km (2.5 miles) WNW of Scheelite, along the North Branch Morgan Creek, about 21 miles NW of Bishop, at 11,000 feet of altitude, in the Sierra Nevada, on private (patented) land (private lease), in a National Forest area. Discovered in 1916. First operated in 1918. Owned by Avocet Ventures Inc. (50%), Canada (1995), and by the U.S. Tungsten Corp. (50%), California (1995). Operated by the Pine Creek Tungsten Mining LLC (100%), Australia (1995). Owned & operated by Union Carbide Nuclear Corp. (1981-1995). MRDS database stated accuracy for this location is 10 meters.

Located in sec. 8, T7S, R30E, MDM: Owned & operated by Avocet Tungsten Inc. (Subsidiary of Avocet Ventures Inc.) (100%), California (1995); owned & operated by U.S. Tungsten Corp. (Subsidiary of Strategic Minerals Corp.) (50%), California (1989 to 1995); Owned by Avocet Ventures Inc. (owner of Avocet Tungsten Inc.) (50%), Canada (1995); Owned & operated by Union Carbide Corp., Mining and Metals Division (100%), California (1981 to 1995).

Mineralization is a Late Cretaceous W ore body in marble with tactite (skarn), hosted in the Tungsten Hills Quartz Monzonite and associated rocks (marble/tactite) (Pine Creek Pendant). The North ore body is irregular, strikes N-S and dips steeply E, at a thickness of 30.48 meters, a width of 18.29 meters, ans a length of 762 meters. The South ore body is 400 feet long, 400 feet wide and 60 feet thick.

The multiple USGS MRDS files present data regarding the ore bodies in a disjointed and at times confusing format. The above data were presented for the North & South ore bodies. The following data were presented without specifying which ore body(ies) they apply to. The dimensions provided indicate that they may pertain to the both ore bodies taken together: thickness: 1,036 meters; width: 23 meters; length: 4,572 meters; area: 50 HA. Ore body No. 1 is disseminated & irregular. Ore body No. 2 is a replacement body. Ore body No. 3 is other (not specified). The primary mode of origin was contact metasomatism. The secondary mode of origin was metamorphism. Primary ore control was a contact zone and the secondary ore control was lithology. Wallrock alteration is slight (carbonitization; silicification). Controls for ore emplacement include the contact of marble beds in the Pine Creek Pendant with quartz monzonite. The scheelite ore body is in metamorphic rocks and is 7 miles long and 1 mile wide. The Pine Creek Pendant marble density in situ is 3.2, deformed in Jurassic (period ?). Skarn (tactite). Local alteration included metamorphism to skarn, ore in fractures, and some replacement by ore. Local rocks include Carboniferous marine rocks, unit 7 (Bishop).

Workings include underground openings with a length of 52,500 meters, developed from 8,000 to 11,500 feet of elevation. The mill is at 7,800 feet.
The overall depth is 300 meters. There are 4 adits at elevations of 10,750 feet, 11,052 feet, and 11,371 feet, plus a large open cut. The plant type is beneficiation (mill) - flotation method.

Reserves and resources data: Type: in-situ; year: 1941; WO3: 0.5 weight percent; year: 1945: demonstrated: 774,748 metric tons ore, indicated 310,262 metric tons ore, measured 464,486 metric tons ore, total resources: 774,748 metric tons ore.

Year: 1945: Mo: 0.823 weight percent.

Estimate year: 1995: demonstrated: 1,360,777 metric tons of ore; total resources: 1,360,777 metric tons ore (WO3: 0.51 weight percent - 1995).

Production at the mine was expected to resume in 1996 according to then competent officials.
